Editor’s Overview

Parlez-Vous Français? by Ricia Sturgeon-Hendrick Brush up on your high-school French — we’re off to Montreal in the Canadian province of Quebec for the once-every-four-years United. Montreal, next to Paris, has the second-largest Frenchspeaking population in the world. I once spoke to the Canadian Elevator Contractors Association (CECA) convention and wanted to use a few words of French. Andre Belanger coached me for two days, and I struggled through, but the welcome was so warm because I tried. We have a special section in this issue that celebrates the United convention, the coming together of members of the National Association of Elevator Contractors, CECA and the International Association of Elevator Consultants, along with a full complement of visitors. The section includes a floor plan, exhibitors list and travel guide. Montreal is an exciting venue, and the convention promises to be well attended. Our cover story is Crystal Clear Vision by Jan Steeger. Schindler’s beautiful elevators are in the LVM Insurance Co. headquarters in Mßnster, Germany. The building boasts three stylish glass-and-steel elevators with visible ropes and pulleys, using Schindler’s PORT system for traffic. There is also a panoramic elevator to the sky lobby. We covered a number of events in the past month. Our Caleb Givens went to Elevator U in Quincy, Illinois, hosted by HollisterWhitney and Illinois State University. With more than 172 attendees (many of them new), this proved to be a good venue for the extensive educational program. All enjoyed visits to both of the hosts. After Elevator U, Givens zipped over to the Building Owners and Managers Association International Convention near Washington, D.C. We attend this event only sporadically but found more elevator people than we had in the past. There were 10-12 elevator companies there, including all the OEMs. We appreciate SnapCab sharing its booth with us. Another event we seldom attend is the Hanover Fair in Germany, but Undine Stricker-Berghoff offered to attend for us, and she found quite a number of elevator component suppliers, as well as thyssenkrupp. President Barack Obama also attended and was greeted by German Chancellor Angela Merkel. Your editor was privileged to attend and cover Liftex 2016 in London. I had help from Bßlent YĹlmaz, Elevator World Turkey’s managing director, and my good friend Martha Hulgan. After three years in the making, this was the best-attended Liftex ever. A day of sightseeing gave us breathtaking views of the city that always seems to host a sea of cranes. London is a visual dichotomy with very ancient buildings standing side by side with very modern edifices.

8 • September 2016

Our Focus Topic this month is Safety and Inspection. First up is Why PESSRAL Is Not PESS by Tijmen Molema. This is an Elevcon paper that examines codes in Europe. Molema suggests that “cherry pickingâ€? between codes can lead to unsafe systems, and he urges using risk analyses. Two articles on new apps also piqued our interest. Breakthrough in Safe and Cost-Effective Elevator Hoistway Control by Stephan Rohr promotes the use of an absolute positioning system and iDiscovery supervisory unit to take over all safety functions in the hoistway. Another article, Speeding Up Elevator Inspections and Reporting by Sanjay Kamani introduces UpVate, a web-based mobile app that could reduce inspection time in a building by a significant amount and time in reporting even more. Speaking of inspectors, our Hanno van der Bijl profiles a longtime friend in Best Bureaucrat: Mike Chavez, chief elevator inspector of Miami-Dade County. Chavez started as an Otis mechanic but now battles condominium boards with one arm and elevator companies with the other. Your editor is always grateful to hear from Chavez, who likes to make sure ELEVATOR WORLD knows what is going on in (his territory). Finally, under our Focus Topic is a Readers Platform from a second-generation union mechanic from the northeast. Something Has to Give by Justin Robert is a passionate plea for safety in a world of too many jobs and too little time or training. He has some great advice for those handling elevator maintenance contracts. We’ve never had an article quite like this — it bears witness from the field. We have two excellent articles on hydraulic elevators. They seem to be making a comeback! The first is a Continuing Education article, Making Hydraulic Elevators Heat Resilient by Parag Mehta of Blain Hydraulics GmbH. The causes of heat generation are explored — too-small tanks, not enough ventilation and poor valve control, to name a few. Mehta suggests solutions and ways to optimize the system. The second article, Smart Hydraulics Guarantee Lowest Cost of Ownership, comes to us from Tony Aschwanden of Bucher Hydraulics AG. This article takes a different tack, discussing how decision-makers now are savvier about not just the up-front installation costs, but also the long-term operating and maintenance costs. We hope you enjoy this issue before you get to Montreal, so when you get there, you can tell everyone you were warned about the “French thing,â€? and you are ready to let the good times roll — or, laissez les bons temps rouler.  đ&#x;Œ?

A Bit More Rope on Ropeless Systems It was interesting to read Robert S. Caporale’s comment in the April edition of ELEVATOR WORLD on “Lifts Without Ropes: How Many Shafts and Cars are Needed?� by Stefan Gerstenmeyer and Dr. Richard Peters (EW, January 2016). I understand and agree that this new technology is difficult to comprehend in the beginning. However, less than 10 years from now, we will likely be experiencing this and other technologies that will radically change the concepts of pedestrian transportation. For example, new technologies such as ropeless elevators, high-speed moving walks and other systems driven by linear drive (LD) technology (magnetic levitation), will appear on the market and become common transportation systems for the next generation of users. It is a known fact that conventional elevator technology of one car per shaft operated by a roping system is no longer suitable for megatall and supertall buildings due to space inefficiency and long travel times. For many years, the simple concept of the conventional elevator has provided reliable and efficient transportation of passengers to their destinations. However, with increased heights, steel ropes are reaching their limits, and building populations are dramatically increasing with heights, resulting in the need for more shafts taking up more building space. The solution to reduce shafts and still move people quickly and efficiently is, at this time, to put more cars into one shaft. This can only be achieved either by employing innovative technology, such as two cars in one shaft (TWINŽ or a double-deck system), or replacing conventional roping systems with newer technologies, i.e., LD without ropes. LD technology has been safely used in many applications, including the high-speed Shanghai Maglev Train System operating at speeds up to 431 kph, for more than 10 years. While breakdowns may occur, LD technology provides a safe, reliable drive system that offers a level of compensatory technology. Should one LD motor fail, it can be supplemented by other, adjacent motors and replaced during the regular maintenance program, allowing the system to remain in service. Therefore, unless a major failure occurs, the system will continue to operate, which is not the case with conventional lifts. Also, in the unlikely event a car needs to be withdrawn from service, it can be moved from the main shaft to a storage or maintenance area similar to that of a metro rail network, allowing immediate resumption of service and causing only minimal delay. With a conventional lift, on the other hand, 100% of the shaft is unusable until an engineer arrives and repairs the fault.

16 • September 2016

In conclusion, the ability of a ropeless lift system to be able to travel both horizontally and vertically allows optimal use of space and the building footprint to continually provide the handling capacity and quality of service in taller and more densely populated buildings, as mentioned in the original article. The below schematic may also assist in demonstrating the working operation of a typical ropeless elevator system:

This schematic originally appeared on page 73 of EW, February 2015, “A Paternoster for the Future.�

NYC Buildings rise from Manhattan to Queens, and a safety campaign is introduced.

3 WTC Tops Out Three World Trade Center (3 WTC) topped out on June 23. Located at 175 Greenwich Street, 3 WTC reached its final height of 1,079 ft (80 stories). New York YIMBY reported that other construction and glass installation still need to be completed prior to the building’s anticipated 2018 opening. It will join 7 World Trade Center, which opened in 2006; 4 World Trade Center, which opened in 2013; One World Trade Center (1 WTC), which opened in 2014; and the World Trade Center Transportation Hub, the main concourse of which opened in March.

worth of public transit improvements to the Grand Central transit hub. When complete, the building is expected to be the secondtallest office tower in the city at 1,401 sq. ft., behind One World Trade Center, also built by Tishman. Kohn Pedersen Fox designed the building to pay homage to the Grand Central Terminal and fit into the skyline alongside the Chrysler Building, located only a block away from the site. The developers are aspiring to Leadership in Energy & Environmental Design v4 Gold certification. Primary construction is scheduled to begin soon, with completion expected in 2020.

One Vanderbilt Progresses Business Online has reported on the One Vanderbilt development slated for East Midtown. In a construction deal worth approximately US$1 billion, SL Green Realty Corp. chose Tishman Construction to manage the construction of the 58-story office development located adjacent to Grand Central Terminal. Additionally, New York YIMBY noted in June that demolition at the site had begun. The high rise will contain 1.6 million sq. ft. of class-A commercial space, a public transit hall and a 14,000-sq.-ft. public plaza. The development will also include US$220 million

The New York City (NYC) Department of Buildings issued a public service announcement on elevators as part of its “Stay Safe. Stay Put.” campaign to reduce deaths and injuries. Advertisements are being run in print, bus-shelter spaces, radio spots and in video form. As run in the New York Daily News in July, they stress for entrapped passengers to not leave a stalled elevator until being assisted by emergency responders. They also instruct them to ring the alarm, relax and refrain from attempting to pry open the doors. An announcement also stated that five people died, and 51 were injured in 56 elevator accidents across the city last year. This is a significant reduction in injuries since 2007, when the figure was 105.

51-Story Building Plans for Upper West Side Released The 666-ft.-tall 200 Amsterdam Avenue for the lower blocks of Manhattan’s Upper West Side was revealed in June. To become the neighborhood’s tallest building, the former synagogue site was acquired for US$275 million in 2015 by SJP Properties. The developer has since gained US$160 million in financing from Mitsui Fudosan. New York YIMBY reports Elkus Manfredi Architects is designing the exteriors, while CetraRuddy is being contracted for the interiors. The building will house 400,000 sq. ft. over 51 floors containing 112 residences averaging in excess of 3,000 sq. ft. each. The site sits on the west side of Amsterdam Avenue between West 68th and 69th streets, bridging the taller buildings of the southern bounds of the Upper West Side (Lincoln Square) and the rest of the Upper West Side, where towers are much shorter. The newly completed 160 West 62nd Street stands as the tallest building in Lincoln Square at 598 ft., while on the Upper West Side proper, the San Remo is the tallest at 400 ft. No completion date has been announced.

Canada Potential industry crisis is highlighted as plans for more high rises develop.

Canada’s Elevator Availability Called “Crisis” The Canadian Press published a report in July after investigating the poor service availability of elevators across Canada. Though some problems are blamed on more elevators (such as Ontario’s 10% increase in installations over the past five years), the source states “insiders” point to aging equipment and structural issues. Last year, in Ontario alone, firefighters responded to 4,461 entrapment calls. That makes an average of more than a dozen a day and double the number from 2001. Among cities, Toronto led the way last year with 2,862 elevator-rescue calls to 911. Next was Montreal with 1,532 calls and Vancouver (in 2014) with 428. Rob Isabelle of KJA — Vertical Transportation Consultants said, “I don’t think we’re heading toward a crisis, I believe we’re already there. If we look at the reliability of a large number of pieces of equipment, it’s really the worst it’s ever been.” He told the source that “companies have been in a race to the bottom in their efforts to grab market share.” Isabelle compared the service maintenance route of approximately 30 years ago, when a mechanic would service 35-45 elevators for approximately CAD$1,000 (US$761) per elevator per month, with today, when that same contract might be worth only CAD$600 (US$456) with each technician responsible for 100 elevators. Likening it to a “downward spiral,” Isabelle said, “Service technicians are getting loaded up more and more, having less time to do preventive maintenance. The less preventative maintenance you do, the more problems you’re going to have.” Compounding the problem is older buildings, in which parts and technicians familiar with the aging equipment are either hard to find or nonexistent. Approximately 1,550 of Ontario’s 18,000 residentialbuilding elevators are more than 50 years old, and another 10,000 are 25-50 years old. As concerns safety, the source stated eight people were “permanently injured,” and another 119 were “slightly hurt” in Ontario elevators last year. Such injuries have been rising by 6% a year for the past eight years.

CRYSTAL-CLEAR VISION At LVM Kristall in Münster, Germany, Schindler designed a verticaltransportation system that blends style, technology and efficiency.

by Jan Steeger


chindler Deutschland AG & Co. KG is justifiably proud of the verticaltransportation system it delivered to client Landwirtschaftlicher Versicherungsverein Münster A.G. (LVM), an insurance firm, for its headquarters in downtown Münster, Germany, in 2014. Consisting of a trio of energy-efficient, stylish elevators, along with a panoramic lift to a sky lobby that offers an “experience in itself,” the system is distinguished by PORT destinationdispatch technology, custom interiors that artistically reflect LVM’s brand and seamless

integration into the striking design of HPP Architects of Düsseldorf, Germany, and South Korean firm Duk-Kyu Ryang.

Project Description With approximately 4,600 employees, LVM is one of the leading insurance groups in Germany. The company laid the foundation for another office building at its Münster headquarters in July 2011. Completed in 2014, the building offers 450 additional workplaces with custom interiors. The project was originally called LVM5, but, due to its tapered, sloped glass façades Continued

and 63-m-tall tower, it is now referred to as the “LVM Kristall.” Despite its distinctive shape, it is not a freestanding building: at approximately 40 m up, the new building connects to the existing LVM tower via a 20-m-long pedestrian bridge, creating a harmonious building complex. Between the two skyscrapers, a city square comprising various elements of art and nature provides an urban link to Münster’s city center.

Interior Concept In the interior, LVM placed great emphasis on an open spatial concept. Instead of a static layout with fixed offices, there are workplaces, meeting and multifunctional rooms on each floor. The color scheme of the office floors reflects the interaction of the seasons, thus ensuring diversity and orientation. The top-floor sky lobby features a glass roof. Here, training rooms and an auditorium span three open levels.

46 • September 2016

Ecology and Sustainability The project was characterized by ecological construction methods and sustainability from the start. The LVM Kristall is one of the first energy-plus buildings in Germany, generating more energy than it consumes annually. The double façade with triple glazing provides for heat insulation. Technical measures and appliances, such as a geothermal energy system for air-conditioning and heating, a photovoltaic system, rainwater recycling, as well as a biogas-fueled combined heat and power generator, contribute to the building’s sustainability. LVM also contributed to sociocultural sustainability by installing an underground parking lot for some 360 bicycles. This is frequently used, as Münster is known to be Germany’s bicycle capital. More than 100,000 people travel the roads by bike every day, and there are twice as many bicycles as residents —500,000.[1]

During the building’s planning phase, the German Sustainable Building Council awarded it with a pre-certificate in its then-highest category, Gold, for its outstanding sustainability features.

The Vertical-Transportation System The lift systems of the Kristall were customized by Schindler and its supplier partners. The three elevators in the heart of the building, which features a firefighter lift, vertically interlace the flexible office concept. Another panoramic lift with a round, glazed cabin operates exclusively on the upper floors of the sky lobby. For the trio of main elevators, Schindler provided the controls, operating system and inverters; Ziehl Abegg, the drives; Pfeifer Drako, the ropes; MEILLER Aufzugtüren GmbH, the doors; Metallbau Burkard, the hoisting cages; and Sautter Lift Components, the safety catches. The panoramic skylobby lift has custom Schindler controls; a Schaefer operating system; Bucher drives;

and doors, hoisting cages and shaft frames by GBH Design GmbH. The lifts of the main building stop at all 19 floors and travel at 2.5 mps. They include two identical passenger lifts that each feature a capacity of 1050 kg. as well as a unit with a capacity of 1250 kg. for firefighters. Since the building was planned as an energy-plus structure, the lifts have not only been comprehensively designed for energy efficiency, but also feed power

back into the supply network of the building via energy recovery using an inverter.

Traffic Management Schindler’s PORT traffic-management technology ensures smooth lift operation, as well as optimum utilization of the system, thereby saving energy and reducing wait times. PORT functions as a modern hall-call, destination-dispatch system for the lift groups. A destination is selected via a small wall-mounted terminal with a touchscreen, microphone,

loudspeaker and card reader in the elevator lobby. An activity sensor activates the system as soon as someone approaches. The traffic-management system not only operates with a programmed database, but also records user habits independently. The personalized screen displays frequently used destinations, according to relevance. The PORT system works even more efficiently if each passenger has an identification medium — such as a card — containing specific user data. At LVM in Münster, for instance, staff members have identification cards that activate special functions. The status of the system can be visually monitored 24/7 in the office of the technical manager. Modernization that includes PORT is possible without restricting capacity. During construction of the new building, three lift systems in the adjacent LVM tower were modernized. There, PORT controllers were connected with the existing control unit as part of a comprehensive modernization. The result stands out: wait times were significantly reduced.

An exemplary solution was found for the windows in the hoistway doors of the firefighter lift. They were designed as special, door-high, vertical window rows.

Design and Technology The lifts of LVM Kristall were harmonically integrated into the architecture. The lobby areas and cabins of the main building were equipped with a checkered plate that is a characteristic of the LVM brand and can be found elsewhere in its buildings. Wall coverings made of slotted wooden panels, combined with polished stainless steel, follow the interior design of the building up to the lift cabins and impart a warm and friendly ambiance. The windows in the hoistway doors of the firefighter lift, which are compulsory in Germany and usually regarded as distracting, were designed as door-high, vertical-window rows. This special construction combined the safety requirements of the firefighters with the design requirements of the architects.

Machine rooms could not be installed above the shaft to the building’s specific design. In line with the belief that “the rooftop is the fifth façade,” the aim was for no technical facilities to mar the smooth exterior surfaces of the glass building. To this end, the engine rooms of the passenger lifts were installed in the third, lower level. The gearless drive of the firefighter lift is located on the 15th, upper level, adjacent to the shaft. Additionally, inclined shaft heads were required. As a special highlight, the color coding of the floors was continued in the lift cabins. The glazed rear panel faces a white-painted and colorfully illuminated shaft wall. Only the firefighter lift has a closed rear panel. Concealed LED headlights, operated via the lift control, adapt to the color code of the respective floor when passing by and impart an individual touch to each of the 19 floors.

Visible ropes and pulleys enhance the diversified experience. Another challenge was the panoramic sky-lobby lift. The lift runs directly through the training rooms on the upper floors. The building’s geometry rendered the installation of shaft pits impossible. The round, free-standing shaft; hoisting cage; and cabin ceiling are made of glass. Thus, each ride is a special event for visitors to the spacious sky lobby.

Making Hydraulic Elevators Heat Resilient The dangers of heat in hydraulic systems and how to guard against them

by Parag Mehta One of the biggest technical challenges a hydraulic engineer faces is designing a heatresilient hydraulic elevator system. Such a challenge becomes even more difficult when the system has to work in an environment with high ambient temperature, a humid climate, poor ventilation and very high usage. A hydraulic elevator is typically made up of components sourced from different manufacturers. Every component manufacturer, a specialist in its own domain, optimizes the design and performance of its own product. Much of the energy and focus during component design is on tolerances, production techniques, minimizing pressure losses, fulfilling elevator safety norms, quality control and overall functionality of the product. It is the job of the system designer to optimize the working of the complete assembly, keeping in After reading this article, you mind its application should have learned about: and operating ♦♦ Understanding the effects of conditions.

how to get this process right, focusing on minimizing heat generation.

Effects of Heat on a Hydraulic Elevator Heat alters the viscosity of the hydraulic fluid, which triggers the problems. Hot (thin) oil results in: ♦♦ Increased leakage within the system (pumps, valves etc.), reducing the volumetric efficiency of the system ♦♦ Erratic hard start-and-stop travel characteristics, over traveling of the floor level, and increased wear and tear of oil seals and components ♦♦ Oxidation of oil accelerates its degradation by changing its properties and reducing its lifespan. A simple checklist sums up everything that can help deliver a heat-resilient elevator system: ♦♦ Source of heat generation ♦♦ Ways to minimize heat generation ♦♦ Calculating and analyzing heat load ♦♦ Optimizing the hydraulic elevator system to naturally dissipate the generated heat ♦♦ Sizing coolers if forced convection is necessary

Source of Heat Generation The hydraulic power unit is made up of a tank, oil, motor, pump, control valve and related accessories connected to the hydraulic cylinder with a hose pipe or a metal pipe. This driving unit is usually located in the machine room or, in some machine-room-less (MRL) units, in the elevator shaft itself.

Figure 1: Schematic of a hydraulic power unit

The following practices can contribute to heat generation of the power unit: ♦♦ Power unit too small for the elevator it is driving ♦♦ Placement within a poorly ventilated or unventilated place, such as too close to a wall ♦♦ Very small machine room ♦♦ Tank made of (nonmetallic) material that cannot dissipate heat effectively ♦♦ Inadequate piping, causing turbulent flow, pressure losses and heat generation As a general rule, the size (volume) of an oil tank should be at least 2.2 X pump flow, with at least 10 cm of space still left from the tank cover to the oil surface when the elevator is on buffer. The unit should be located in a room with cross-ventilation, which can help the heated air dissipate quickly. If the installation is an MRL type, place the power unit in a wall closet with an opening into the shaft. This helps cool the tank automatically as the car movement in the shaft pushes air on the tank with its movement (Figure 2). Metallic tanks are preferred, as they can dissipate heat much more easily than fiber and plastic tanks. Adequate piping size should be selected, and the usage of reducers, unnecessary bends and adapters should be avoided.

Figure 3: Oil viscosity grade table

Oil Using the correct oil type can significantly contribute in keeping oil temperature under control. Hydraulic fluid best suited for elevator application is one that has a relatively low change in viscosity when its temperature changes. The temperature and viscosity of hydraulic oil is inversely related: oil viscosity decreases with increase in temperature. The viscosity index (VI) is a single-number representation of the viscosity temperature characteristics of a fluid. The greater the value of the VI, the smaller the variation in viscosity for a given change in temperature or vice-versa. Hydraulic lifts consistently used in warm ambient temperatures (above 30°C) and running in heavy traffic should use an ISO VG 68 type of oil. Oversizing the tank for it to contain oil volume three times the pump flow should be used when temperature of the oil during the working cycle of the elevator rises by 25-30°C.

Control Valve

Figure 2: MRL hydraulic elevator system


A flow control valve regulates the flow of oil by letting the excess oil flow back to the tank during the bypass, acceleration, deceleration and leveling stages, giving passengers a smoother ride experience. Many different types of flow control valve specifically designed for hydraulic elevators are available. These range from the simplest and most widely used mechanical valves, servo electronic valves with proportional solenoids, to variable-voltage, variablefrequency (VVVF)-driven valves. A wrongly adjusted control valve can contribute to heating of the oil. Improperly set pressure-relief valve, longer bypass and leveling times can impact the oil temperature on every run. Undersizing the valve, especially at high operating pressure, can also contribute to unnecessary temperature increase. Using the Continued • September 2016

wrong valve type in a heavily used hydraulic elevator, like installations in public places or hospitals, for instance, can contribute to the heating of the system. Correct valve adjustments are critical for trouble-free operation and minimizing wear and tear of the components and oil seals. A wrongly adjusted valve during the installation phase not only results in erratic travel characteristics, but also keeps heating the oil for the rest of the time. For example, Figure 4 shows a wrongly adjusted valve with unnecessary longer leveling time; whereas Figure 5 shows the travel with optimum leveling time. Table 1 shows optimum bypass, acceleration, deceleration and leveling timings of valve adjustments.

Figure 4: Valve adjusted for longer leveling time

Undersizing Using the control valve at or more than the full flow capacity causes high pressure losses and turbulence, which heat the oil quickly. High operating pressure (more than 65 bar) adds to the heating problem. Manufacturers’ recommended operating flow range for the given size should not be ignored in the interest of minimizing pressure losses Figure 5: Valve adjusted to correct leveling time at maximum flow.

VVVF valves with inverters are the best option when temperature and pressure compensation are desired with dynamically changing operating conditions beyond the scope of simple mechanical control valves. An inverter-based system not only minimizes heat generation, but also energy consumption by up to 60%.

Calculating and Analyzing Heat Load The first law of thermodynamics says that energy cannot be created or destroyed, simply transformed from one type to another. Thus, in a hydraulic elevator system, energy must be added to the hydraulic oil to elevate the car to its destination. An energy source such as an electric motor is needed to drive a pump to convert the mechanical energy into flow. Resistance to flow in the hydraulic system creates pressure, the energy of which actuates the cylinder of the elevator system. Hence, the complete hydraulic elevator system is actually an energytransfer system. As the energy is Continued

Figure 6: Effects of motor and valve types on thermal balance temperature: Z: starts per hour; MV: mechanical valve; EV: electronic valve[1]

simultaneously transformed from one type to another, some of the energy in the system is converted into heat and is no longer available for useful work. The lost energy that gets converted into heat increases the temperature of the oil in the tank. The heat in the oil is then naturally dissipated to the environment until the temperature gradient between the oil and ambient temperature equalizes. Heat dissipates from a hydraulic system mainly in two ways: natural convection and forced convection. Natural convection takes place as heat moves from the various system components to the surrounding air because of the temperature gradient. It is good when natural convection dissipates all the heat generated by the elevator system. If not, system temperature will continue to rise, thereby necessitating a heat exchanger, which is the second heat-dissipation mode (forced convection). A third heatdissipation mode, radiation, is in action, too, but its effect is essentially negligible. In principle, the heat generated by the system needs to be effectively dissipated to maintain the oil temperature. When heat generated is in excess of the heat that can be dissipated, the oil temperature will rise, and an oil cooler will be necessary as an additional method by which to maintain oil temperature. An oil cooler can be installed to maintain the oil temperature within a specified range; however, it comes with an increase in cost and power consumption. As a general rule of thumb, a temperature rise of 0.5°C can be considered for every 10-bar pressure drop across a flow passage. One of the main objectives of the power-unit design is to balance heat losses at an acceptable oil temperature by natural transfer from the oil to pipes, actuators and a reservoir, and subsequent dissipation into the air. The hardest calculation is the heat balance, which requires a true mathematical summation of heat entering and leaving the hydraulic system. In practice, some empirical formulations are used in the industry to decide the necessity and the size of the oil cooler. The performance characteristics of a hydraulic power unit highly depend on the working temperature range, type of hydraulic oil and oil cleanness level, air bubbles and water. To obtain a detailed and realistic estimate, many internal and external factors are to be considered simultaneously. Ultimately, it

56 • September 2016

is the equilibrium of heat energy entering and leaving the hydraulic system that has to be factored in the calculation. A true formulation should consider: ♦♦ Ambient temperature ♦♦ Average trips per hour ♦♦ Average load per trip ♦♦ Average travel height ♦♦ Speed of the elevator ♦♦ Total travel, bypass and leveling times ♦♦ Motor and pump sizes and their efficiencies ♦♦ Pressure drop in valves and piping ♦♦ Air ventilation in the machine room and shaft ♦♦ Location of the tank in the machine room ♦♦ Internal tank design and tank size All these factors have to be evaluated in each elevator design before establishing the heat balance equation. Calculation for heat balance is performed at a critical limit where the oil temperature and ambient temperature are selected at their limit values, such as 55°C (130°F) and 30°C (86°F). At that critical situation, the amount of generated and dissipated heat power is calculated with respect to number of round trips in 1 hr. This calculation, however, does not consider the time until the critical limit has been reached. Moreover, the calculation is not cumulative. When the duration to reach the critical level may be long enough, the cooler may not be needed at all. Therefore, a better assessment method that considers the time parameter may give more realistic results. A very general equation for calculating the heat generated is as follows: Heatgenerated (kW) = 5.9 * λ * Totalweight * stroke * Motor starts per hour * 10–6

(Equation 1 [metric]) where λ is the average factor for the value of the product of weight, stroke and motor starts 0.5 is considered an average value (0.8 in extreme cases). Totalweight is the summation of all weights (payload, car weight, etc.) in kilograms. Stroke is the stroke of the piston in meters. Motor starts per hour is the number of times an elevator gets up calls in 1 hr. Heatgenerated (hp) = 0.81 * λ * Totalweight * stroke * 1.34 * Motor starts per hour *10–6

(Equation 1 [Imperial]) where λ is the average factor for the value of the product of weight, stroke and motor starts. 0.5 is considered an average value (0.8 in extreme cases). Totalweight is the summation of all weights (payload, car weight, etc.) in pounds. Stroke is the stroke of the piston in feet. Motor starts per hour is the number of times an elevator gets up calls in 1 hr. A general equation for calculating the heat dissipated is as follows:


Heatdissipated (kW) = 10473.5 * ∂ ∗


TankArea + Pipearea + Cylinderarea + Pistonarea * Difftemp * 10–6

(Equation 2 [metric]) where Tankarea, Pipearea, cylinderarea and Pistonarea are the surface area in square meters. Difftemp is the temperature difference the oil is subjected to in degrees Celsius. (1.0 to 1.3) is the factor used for the tank size. A lower value should be used for a small and light-colored tank; a higher value should be used for a large and dark-colored tank. Heatdissipated (hp) = 4.87 * ∂ ∗


TankArea + Pipearea + Cylinderarea + Pistonarea * Difftemp * 10–6

(Equation 2 [Imperial]) where Tankarea, Pipearea, cylinderarea and Pistonarea are the surface area in square inches. Difftemp is the temperature difference the oil is subjected to in degrees Fahrenheit. (1.0 to 1.3) is the factor used for the tank size. A lower value should be used for a small and light-colored tank; a higher value should be used for a large and dark-colored tank. If heat generated is less than heat dissipated, no forced cooling is required. Formulations and equations mentioned are generic and should only be considered as reference. Details specific to the elevator installation, application and power-unit design should be factored in to get more accurate results before arriving at any conclusions. For more details, refer to “Importance of Thermal Balance for Hydraulic Elevators.”[1]

Optimization Apart from the aforementioned options on reducing heat generation, the design of hydraulic elevator systems can be further optimized to dissipate heat more effectively in a short duration of time by: ♦♦ Using metal tanks with a larger vertical surface area, effectively exposing a larger area for optimum heat dissipation ♦♦ Elevating the tank so as to have good air circulation below it

58 • September 2016

Figure 8: Cooler types; courtesy of Seim S.r.l.

♦♦ Placing the power unit in a proper ventilated area or shaft closet for natural cooling with every run of the elevator ♦♦ Avoiding concealed piping, if possible, to dissipate heat effectively ♦♦ Using an oversized tank, which can contain more oil volume for a time-to-heat advantage ♦♦ Not exposing the power unit to direct sunlight or any other heat-generating source ♦♦ Using a VVVF control-valve system where elevator usage is high so as to generate much less heat ♦♦ Selecting system components with low pressure losses ♦♦ Using the correct oil type appropriate for the elevator application ♦♦ Sizing coolers if forced convection is necessary In a true balance, what goes in must be accounted for, either as a temperature increase or transfer of heat out of the system. Thus, if generated heat is higher than that dissipated, a heat exchanger with a cooling capacity of that difference is selected. When designing a new hydraulic elevator system, a good rule of thumb is that a cooler should be sized to remove approximately 25-30% of the input power. Cooler manufacturers have selection charts that make the selection of coolers relatively easy. The size of the cooler is based on the amount of heat (in kilowatts) that needs to be neutralized with respect to a temperature difference (△T) in accordance with ambient temperature. Figure 7 shows a typical selection chart of oil cooler sizes from a cooler manufacturer. An oil cooler (heat exchanger) typically operates with the help of a thermostat switching the cooling circuit on and off. The operating temperature of the thermostat contact can be set from outside by means of a hand wheel. The sensor element is immersed into the oil. The thermostat of the oil cooler should be adjusted so it comes into operation after a 10-12°C increase from the ambient temperature. A pump is used to deliver hot oil from the tank to a heat exchanger. Oil is cooled there by a motor-driven fan – a process similar to the water-cooling system in an automobile. The cooled oil is then pumped back into the tank for use by the elevator system. The exchanger is installed on the wall of the machine room such that it blows warm air out. The calories (amount of heat transfer) depend on the size of the cooler.

Refrigerated oil coolers are uncommon but can also be found in installations where the ambient temperature is very high and the elevator is used frequently, such as in shopping malls, hospitals, exhibition centers, etc. A refrigerated oil cooler works very much on the same principle as a refrigerator. The warm oil from the tank, which is circulated by means of a pump, exchanges its heat with the coolant, being circulated in the refrigerator by a compressor. Thus, the oil is quickly cooled and delivered back to the hydraulic tank.

Cranes are prevalent throughout London.

Best show in 28-year history held in London. by Ricia Sturgeon-Hendrick and Bülent Yılmaz When arriving in London, one cannot avoid the bevy of construction cranes. They are everywhere in the city and in the villages surrounding it. Two recent mayors of London approved almost any kind of building – some 80% luxury apartments – and much of it speculative. This bubble may eventually burst, but, in the meantime, it is good news for the lift industry, which is booming. In this atmosphere of plenty, Liftex 2016, organized by the Lift and Escalator Industry Association (LEIA), was assured a good reception. Held once every three years, Liftex is the U.K.’s leading event for the lift, escalator and access industry. This

year’s event took place on May 25-26 at ExCeL London. More than 100 companies (including associations and press organizations) from 14 countries attended the exhibition, including ELEVATOR WORLD and EW Turkey. The countries represented at (and the number of companies taking part in) the expo are as follows: U.K. (75); Italy (nine); Germany (eight); Spain (four); Turkey, U.S. and France (two each); and Greece, Croatia, Switzerland, Finland, Netherlands, Austria and South Korea (one each). While exhibiting companies made strong impressions in their booths, the activities of both companies and organizers became

the center of attention. Every day, traffic in the expo area was quite heavy, and visitors spent time looking at equipment and asking questions. LEIA reported that Liftex 2016 was officially the best event in the show’s 28-year history. Exhibitor feedback also supports this assertion. Onsite research revealed exhibitors rated visitor quality as the highest ever, with 97% planning to exhibit at the next Liftex. The show also saw a 20% increase in exhibitors and 15% increase in visitor numbers. Nick Mellor, LEIA technical director, said the event organizers were delighted with the quality of this year’s Liftex in

inquisitiveness can lead them into a little bit of trouble. The campaign includes a little boy named Liam, who is a character of a delightful storybook that gently teaches children to be safe around lifts. The campaign will continue online, via social media, throughout the summer to coincide with the busiest family time of the year. The book, which already won recognition at the LEIA booth, is also freely available on It is also possible to join campaign talks on @liamloveslifts or www.

terms of visitors and exhibitors. He also called the show visually striking, adding: “The exhibitors put a huge amount of effort into creating unique and distinctive stands. We are also delighted to have achieved our objective of attracting new audiences to the show. Through an extensive marketing and public-relations campaign, we have widened its appeal to those working in facilities management and local authorities, as well as welcoming our traditional visitors back.” LEIA asked exhibitors and dignitaries to cocktails after the first evening’s close. This event was so packed that it was difficult to take photos. Taking place in the expo space, the event atmosphere was quite lively. Also on the first day of the exhibition, Elevation, the British magazine for the elevator industry, treated its guests to a spectacular dinner at Tapa Restaurant. Among the guests were your authors; Martha Hulgan, Elevator World board member; Zhang Lexiang, China Elevator Association secretary; Dirk Schoeffler; and several guests from the industry and Elevation family. Your authors would like to take this opportunity to thank the owner of Elevation, Ish Buckingham, for his hospitality and special attention to each guest. LEIA launched a safety campaign at the exhibition named, “Little Fingers,” which encourages children and their families to use lifts safely. The campaign acknowledges and celebrates the fact that small children love lifts and that sometimes, their

The events taking place concurrently with Liftex 2016 were also welcomed with interest. Starting at 11:30 a.m. on both fair days and launched by fair organizer LEIA, the free CPD-certified seminar program ran as follows.

The Lift and Escalator Industry Association (LEIA) is a trade association and advisory body for the lift and escalator industry. It was formed in 1997 by the merging of two longstanding associations, the British Lift Association and the National Association of Lift Manufacturers (which have histories dating back to the early 1930s). With membership covering some 85% of the lift and escalator industry, LEIA provides a single voice for the sector. LEIA members supply passenger and goods/ service lifts, stairlifts, home lifts, lifting platforms, escalators, passenger conveyors and a range of components and services for such products. Members also handle the maintenance of more than 250,000 products that fall within the scope of the association.

It was lucky that Elevator World, Inc. Board Member Martha Hulgan was able to get away from her own consulting practice to come to London with me and help in the Liftex booth. We were shorthanded, and Martha sells Elevator World products wherever she goes. Since we were going to be there anyway, we took a few days before Liftex to see the sights. In one day, we managed to tour the Tower of London, visit London Bridge, ride on the London Eye and eat an extravagant English dinner of roast beef and Yorkshire pudding. The next night, we saw the play “Beautifulâ€? in a theater that was well over 100 years old. We wanted to have a real English tea with Pat Gale, but couldn’t work it in. We were so glad she came to visit us in our booth at Liftex. Of course, the main thing that interested Martha were the elevators at our hotel (Royal Horseguards). When the doors opened and closed, a red or green light appeared alongside the opening, and a voice announced the doors were opening or closing — and gave a safety warning. We spent much of the Liftex expo looking for those door lights. Once an elevator woman, always an elevator woman!  đ&#x;Œ?

A Feast for the Senses Awaits Visitors to Historic, ForwardThinking Montreal.

by Kaija Wilkinson The selection of Montreal as the host city for United 2016 is sure to please lovers of art, history, architecture, shopping and fine dining. The city offers a wealth of all of these things, and members of the Canadian Elevator Contractors Association (CECA), International Association of Elevator Consultants (IAEC) and the National Association of Elevator Contractors (NAEC) and their guests will have the opportunity to gain a good feel for the city through both activities planned by NAEC and on their own. For some visitors, the opportunity to explore will begin as soon as they debark their planes. The recently expanded Montréal–Pierre Elliott Trudeau International Airport, itself an architectural jewel located approximately 20 min. from downtown, offers a taste of what’s to come. A 65,620-sq.-ft. expansion boasts 8,611 sq. ft. of retail (including a long list of local restaurants), three large art installations and four display cases showcasing the city’s

major art and history museums. Hundreds of millions of dollars were spent infusing the airport with a Montreal flavor. Montreal is a land of natural beauty, located on a 499-km2 island in the St. Lawrence River with the lushly landscaped Mont Royal Park serving as a backdrop. Approximately 80 different kinds of food are served in 6,000 restaurants with a variety of price points. Montreal is a city known for excellent French cuisine, and, if you opt for a French restaurant, chances are you can try out your French on the staff. More than half of Montreal’s residents speak French, making it the second-largest French-speaking city in the world after Paris. Montreal’s Metro serves areas unreachable by foot, and the weather in September is typically lovely, with high temperatures in the low 70s (Fahrenheit) and lows in the 50s. The city’s downtown and various neighborhoods are considered safe, clean and pedestrian friendly. Continued

United will be held at the Palais des Congrès de MontrĂŠal convention center in the Quartier International district downtown. While its most striking feature is the nearly 400 brilliantly colored and transparent glass panels that make up its façade, the facility is an expression of Montreal itself, integrating three centuries of history that includes: ♌♌ The façade of the Rogers and King Foundry, built in 1885 ♌♌ The façade of Fire Station No. 20, constructed by Louis-Roch Montbriand in 1908 ♌♌ The Art Deco Tramways Building, built in 1928 and preserved in its entirety ♌♌ The Palais de Congrès’ original building, designed in the 1970s by architect Victor Prus ♌♌ The 2000-2002 expansion overseen by architect Mario Saia, which includes remarkable features such as The Lipstick Forest art installation by landscape architect Claude Cormier; it consists of 52 hot-pink concrete “treesâ€? near the venue’s Hall Place Riopelle. Host hotels are the Le Westin Montreal Downtown, which opens onto the cobblestone streets of Old Montreal; InterContinental Montreal, connected to the shopping destination Underground City, and the Hyatt Regency, which boasts direct underground access to the Palais des Congrès, Chinatown, Old Montreal, Place des Arts and the metro. United organizers plan optional activities to provide visitors an opportunity to get to know the city. For sporting types, there will be golf on enchanting Ile Bizard Island located minutes from downtown. A walk/run is planned that will take participants through Old Montreal and along the promenade overlooking the St. Lawrence River at the Old Port. A bus/walking tour will give visitors insight into Montreal’s history, architecture and attractions, including Underground City, Place des Festivals, Le Plateau-Mont Royal boroughs and Old Montreal, which has one of the largest concentrations of 17th-, 18th- and 19th-century buildings in North America. An extended stop will allow participants the time to take in the grandeur of Notre-Dame Basilica, built over several decades in the 1800s in a dramatic and colorful Gothic Revival style. Instead of religious scenes, its intricate stained-glass panels depict scenes from the city’s religious history. So whether one is dining, shopping or taking in the artistic and historic sights, a visit to Montreal is sure to result in lasting memories.   đ&#x;Œ?

The American Safety Code for Elevators and Escalators, Part Two Explaining the focus and construction of the important American standard between its inception in 1921 and 1931 by Dr. Lee Gray, EW Correspondent The first three editions of the American Safety Code for Elevators and Escalators employed the same organizational scheme: one or more introductory sections followed by a section titled “Definitions” followed by the code’s core content, expressed as a series of “rules” organized into seven “parts.” The introductory sections explained the code’s purpose and provided general guidance on its use. These sections increased in content and complexity with each subsequent edition. The definitions section also steadily increased in size, growing from 40 terms in 1921 to 82 terms in 1931. And, although the text of some of the rules was modified from edition to edition, its overall focus remained largely unchanged in these early code editions. However, these rules cannot be understood without first understanding the editorial development of the introductory and definitions sections.

First Edition The first edition, A Code of Safety Standards for the Construction, Operation and Maintenance of Elevators, Dumbwaiters and Escalators: 1921 provided a minimal introduction, which was simply titled “Application of the Code.” This was divided into three paragraphs (each identified by a lowercase letter) and included one note: “a. This code of safety standards is intended as a guide for the construction, maintenance and operation of elevators, dumbwaiters, escalators and their hoistways except as stated in the following paragraph. “b. This code does not apply to belt, bucket, scoop, roller or similar inclined or vertical freight conveyors, tiering or piling machines, skip hoists, wharf ramps or apparatus in

kindred classes, amusement devices, stage lifts or lift bridges, elevators of capacity exceeding 30,000 pounds and platform area exceeding 300 square feet when suspended by cables near each corner of the hoistway and at additional positions, nor to elevators used only for handling building materials and mechanics during the building construction. “NOTE: The types of apparatus listed above should be made subject to suitable specifications for each type. “c. The code recognizes the deteriorating influence of wear, rough usage, and the atmospheric conditions under which elevator apparatus, particularly door locks, interlocks and electric contacts, are required to operate. In the design and installation of such apparatus, due regard must be given to these conditions and to the construction upon which such apparatus is mounted.” This series of statements reflects, perhaps, the relative newness of the idea of a national code: it was intended as a guide, rather than a set of prescriptive rules, it had a specific application, and it recognized the realities of elevator usage. It is also important to note that these statements did not, in fact, provide any guidance on the actual application or use of the code.

Second Edition The second edition, Engineering and Industrial Safety Standards: A Safety Code for Elevators, Dumbwaiters and Escalators: Rules for Construction, Inspection, Maintenance and Operation: 1925, included an introduction and a section titled “Scope and Purpose.” The introduction offered a more fulsome description of the code’s proposed application: Continued

“This Code is intended as a guide to state and municipal authorities and may be adopted by them in whole or in part. It is also intended for use as a standard reference for safety requirements for the use of elevator manufacturers, architects, and consulting engineers. For this purpose it may be used to advantage in connection with the Standards for Elevator Construction now in preparation under the American Engineering Standards Committee procedure. It is also intended as a standard for use by hotels, department stores, office buildings and other users of elevators through voluntary application.” The “Scope and Purpose” section began with a revised version of the first edition’s three-paragraph introduction. The opening sentence, now labeled “Scope,” read as follows: “This Code of safety standards covers the construction, inspection, maintenance, and operation of elevators, dumbwaiters, escalators, and their hoistways except as stated in the following paragraph.” (The paragraph on elevator types not covered by the code remained the same.) An additional subsection titled “Purpose, Interpretation and Exceptions” expanded the introduction’s explanation of the code’s proposed application and use: “The purpose of this Code is to provide reasonable safety for life and limb. In case of practical difficulty or unnecessary hardship the enforcing authority may grant exceptions from the literal requirements or permit the use of other devices or methods, but only when it is clearly evident that reasonable safety is thereby secured. Note: It is suggested that in cases where exceptions are asked for, the enforcing authority consult with the Committee on Elevator Safety Code, care of American Engineering Standards Committee.” Although these statements retained the use of the term “guide,” they also added the concept of inspection and provided recommendations regarding the code’s use by municipal and state authorities, architects, engineers and the elevator industry. The description of the process for requesting “exceptions” appears to somewhat contradict the idea that the code “may be adopted. . . in whole or in part” and, perhaps, expressed the authors’ desire

for stricter implementation and interpretation of the code’s contents. The reference to the development of a parallel document – “Standards for Elevator Construction” – is also intriguing. However, thus far, these standards have not been found (although the search continues, and they may be the topic of a future article).

Third Edition The third edition of the code, American Standard Safety Code for Elevators, Dumbwaiters and Escalators: Rules for Construction, Inspection, Maintenance and Operation: 1931, included a forward and an introduction, the latter of which was divided into two sections: “General” and “Scope and Purpose.” These sections contained much of the same text found in the second edition with a few editorial modifications and additions that responded to the ongoing implementation of the code. This was reflected in the forward, which noted: “The application of this Code in the formulation of various state and municipal codes emphasized the need for its further development and extension. Accordingly, the American Society of Mechanical Engineers requested the

American Standards Association to authorize the organization of a Sectional Committee to undertake this revision.” While this serves as a general indication of the code’s usage, it raises questions regarding the degree to which, by the late 1920s, the code had been adopted and/or used to formulate local and state elevator codes. This aspect of its use was also reinforced by a subtle shift in language. The sentence “This Code is intended as a guide to state and municipal authorities and may be adopted by them in whole or in part” was revised to read, “It is intended as a guide to state and municipal authorities in the drafting of their regulations and may be adopted by them in whole or in part.” This statement was followed by specific advice on the development of new codes: “It is suggested that before adopting this Code for state or municipal use or drafting a code with this as a basis, a careful survey be made of the state or municipal regulations providing for prior publication, public hearings, or similar means of bringing such regulations before the public. Whether required by law or not, public hearings are beneficial in that they permit building owners to voice their objections to particular rules and at the Continued

The new terms primarily addressed cars and gates. The definitions section of the third edition reflected the Table 2: “Modified and New Defined Terms,” second edition ongoing development of the code (the number of same time provide an opportunity for the terms increased from 62 to 82), as well as authorities to explain the reasons for such rules, and the public is thus informed of the dynamic nature of code writing.

♦♦ 1925: “A passenger elevator is an elevator that is designed to carry persons to its rated capacity.” ♦♦ 1931: “A passenger elevator is an elevator that is designed to carry persons to its contract capacity.” The first revision simplified the definition, whereas the second – changing “rated capacity” to “contract capacity” – represented an attempt to clarify the code’s intentions. The term “rated load” had been defined as “the load in pounds which the elevator is designed and installed to carry in accordance with this code.” This term was deleted and replaced in the third edition by “contract load,” which was defined as “the load specified in the contract for the purchase of the elevator, or in the application for permit.” The changes to the definition of “hoistway door interlock” included the modifications noted above, in addition to other changes in the text: ♦♦ 1921: “A hoistway door interlock is a device the purpose of which is: First, to prevent the movement of the car: a. Unless only that hoistway door, opposite which the car is standing, is closed and locked (Door Unit System); or b. Unless all hoistway doors are closed and locked (Hoistway Unit System); and Second, to prevent the opening of a hoistway door from the landing side: a. Unless the car is standing at rest at that landing; or b. Unless the car is coasting past the landing with its car control mechanism in the STOP position. A hoistway door or gate shall be considered closed and locked when within four (4) inches of full closure, if at this position and any other up to full closure the door or gate cannot be opened from the landing side more than four (4) inches. Interlocks may permit the starting of the elevator when the door is within four (4) inches or less of full closure, provided that the door can again be opened up to four (4) inches from full closure from any position within this range except that of full closure. (Note: The interlock shall not prevent the movement of the car when the emergency release hereinafter described is in temporary use or when the car is being moved by a car-leveling device.)” Continued • September 2016

(Note: The “closed positionâ€? for landing doors and gates for various types of elevators is specified under Rules 121c, 121d, and 121e.) These changes appear to illustrate an editorial process that sought increased clarity and avoided unnecessary information.

IGV Group: A 50-Year Passion Italian manufacturer celebrates golden anniversary in style.

submitted by IGV On June 25, IGV Group celebrated its 50th anniversary with a party at its headquarters in Vignate, Italy. More than 600 guests, from sector operators to representatives of authorities and employees, enjoyed entertainment that included cooking demonstrations, live music and corde lisse rope acrobatics on the side of the building. Eng. Giuseppe Volpe, who founded IGV in 1966, was joined by his son, Matteo, IGV general director; his daughter, Maria, journalist; and her two children, Lucia and Giuseppe. The story of the family goes on and keeps on spreading the IGV brand worldwide. The company is intimately connected to its founder, who, 50 years ago in a small office with three people, gave rise to the IGV adventure. Today, IGV is a leading company in the lift sector, with 200 employees and an ever-growing market. During his speech, Giuseppe Volpe drew attention to the need to never give up and keep on innovating. He thanked family, employees, customers and suppliers for taking part in the celebration and remarked how IGV has survived tough times, such as the 2009 financial crisis. Observing the life of a company is similar to that of a man, he reflected on milestones in IGV’s 50 years, such as the debut of its signature product, DomusLift. Giuseppe Volpe stated he has no intention of retiring and ended with: “I am sure you will never leave the IGV brand, because you know that this company is supported by passion, responsibility, heart and mind, innovation and tradition, care for details and technology, quality and flexibility, research and professionalism, and loyalty. This will never change. I promise you. And as you know, I keep my promises.” Continued

Matteo and Maria Volpe then introduced the new DomusLift Art — Limited Edition line, a new version of the lifting platform enriched with Italian art masterpieces. They pulled back an ivory satin sheet to reveal lifts decorated with fine art by Francesco Hayez and Michelangelo. This is the concept of the new line: to provide the opportunity to enjoy art, genius and harmony at home. The 50th-anniversary party was a great success. Guests mingled and enjoyed the flavors of gourmet Italian hors d’oeuvres and the music of a saxophone player. Children were treated to face painting and balloon sculpting. The warm and informal atmosphere was a welcome reward for the hard work of these last 50 years.   đ&#x;Œ?

EU Conference The small town of Quincy, Illinois, welcomes a big crowd.

by Caleb Givens This summer, 172 industry professionals from across the country joined together in Quincy, Illinois, for the 19th annual Elevator U (EU) Conference. The small town is home to Hollister-Whitney Elevator Corp.’s factory, which, along with Illinois State University (ISU) in Normal, was the generous host of this year’s conference that took place on June 20-23. The Holiday Inn & Conference Center served as the venue for the 47 vendors, speakers and attendees. As always, the first day began with a golf outing. This year’s took place on the beautiful course at Spring Lake Country Club. That evening, the EU Board of Directors held its meeting, while the early arrivers gathered for dinner, drinks and conversation.

industry. He emphasized the crucial task of taking control of the car when performing any maintenance or inspection. Shepherd said to always keep safety in mind by remembering your loved ones who are counting on you to return home at the end of the day. He also stressed how elevator people should always take an opportunity when discussing their jobs to tell those loved ones about the proper and safe way to ride elevators and escalators. Following Shepherd was Dr. Clemense Ehoff, assistant professor in the Department of Accounting at Central Washington University, who presented on “Maintenance from a Business Perspective.� Dr. Ehoff wrote his PhD dissertation on the elevator industry, and, in his own words, might be the only person who is not an engineer to have done so. “I tried to apply some business models to some of the problems the elevator [industry] was facing,� said Ehoff. It was not long before much discussion and debate erupted in the audience, proving the importance of this issue and the networking value of the EU conference.

figured out that we all have a lot of the same challenges. And part of this conference is to work together to try to solve problems and provide input and experience.â€? This year’s conference once again proved to be highly educational for all types of professionals with varying years of experience. Next year, EU will be in Charlottesville, Virginia, hosted by The University of Virginia (UVA). Neil “Eddieâ€? Morris, Elevator Maintenance senior supervisor at the university, is looking forward to it already. He stated: “[EU] provides an avenue for colleges/ universities to share elevator-industry information, such as new technology, safety guidelines, best practices and networking. I’ve been a proud member since 2010, and it’s exciting to have the opportunity to host the [EU] Conference in June 2017 at [UVA]. Charlottesville is rich in history and education, with the homes of past presidents Thomas Jefferson and James Monroe being only about 15 min. from campus. The locals enjoy the cultured aspect of the region, including museums, golf courses, and wineries/ breweries, to name a few. I believe it would be safe to say that there is something here for everyone!â€? For more information about EU, how to get involved and the upcoming conference, visit    đ&#x;Œ?

Hanover Fair in Germany Global companies and SMEs display products with many technological innovations.

by Undine Stricker-Berghoff The Hanover Fair in Hanover, Germany, is the world’s largest industrial fair and Industry-4.0 platform. (The term “Industry 4.0,” or the “fourth industrial revolution,” was first used at the Hanover Fair in 2011 to describe the use of cyber physical systems in manufacturing and products.) The fair took place over five days on April 25-29. More than 190,000 technical participants visited more than 5,200 exhibitors in 16 halls and open-air space. Approximately 5,000 visitors came from the partner country, the U.S. Thirty percent of the visitors were from abroad, while 58% of the exhibitors were from abroad, representing 75 countries. Elevator component companies were present from around the world, with more than 30 exhibitors and more than 130 products.

Vertical and Horizontal Transportation at the World’s Biggest Fairgrounds

Facility Manager Mathias Dorsch has a three-person team exclusively dedicated to elevator and escalator maintenance. They make sure approximately 220,000 visitors, tens of thousands of exhibitors and staff are safely moved through 466,100 m2 of halls, 58,000 m2 of outdoor space, 26 pavillions and a 35-room convention center. The team brings units into and out of service, deals with disturbances, and performs most repairs and maintenance.

Elevator Component Exhibitors

Elevator components, mainly machines, were displayed at the fair. Most of the companies came from Germany and Europe. Some examples are: ♦♦ Danfoss provided an overview of its products and kept close contact with its (potential) customers. It displayed a frequency converter with the VLT® Lift Drive software specialized for elevators. Torsten Harders, sales engineer, Drives, stated this solution with high clocking

frequencies guarantees low motor noise. The company also has a patent for load detection, which is approved by the Institute of Electrical and Electronic Engineers. Lafert displayed one gearless elevator machine. The company said it received questions from around the world concerning its products during the fair. Most people came from builders and buyers asking for product specifications in great detail. Dr. Daniel Wojtkowiak, Senior Sales Manager at Switch, presented the new LED shaft light for elevators with emergencylight function, exceeding the new European safety regulation EN 81-20 The LED strip, with a maximum length of 50 m, consists of two separate electric circuits. The majority of LEDs are connected to the shaft light for common operation, while every 10th LED is connected to the emergency path. Thus, a part of the LEDs can be fed with low-voltage power provided by rechargeable batteries. Sales Manager Doris Pilz of TÜV Nord explained the company’s expertise on elevators. At the booth, she provided extensive information and gave advice mainly on user duties, operational safety according to new German and European rules and regulations, inspection in general, and the new accompanying TÜV Nord services, to different customers. The visitors came to the fair and the booth primarily for the use of Industry-4.0 technologies. With approximately 3,000 employees, VOL-Stahl produces special steel profiles, for example, for elevators. The company services about 40% of the Russian elevator market. In Germany, it is represented by a daughter company with 15 persons with a large warehouse from which it delivers to the European Union. It has contacts in the U.S. and delivers small quantities there, too. The company made its first appearance at the Hanover Fair eight years ago in a Russian common booth. This year, it had customers visiting its booth, and it won a few new customers. Dr. Sergey Voloskov, CEO of Omutninsk Metallurgical Plant, said, “We are here to understand the market. In the beginning, we came to build up new contacts. Nowadays, we just represent our already known products.” Ziehl-Abegg displayed a compact 1050-kg-capacity elevator machine that runs at 1.6 mps with 2:1 suspension for use with plastic-coated ropes. Dieter Rieger explained this contributes to lower noise emission. With regards to the fair, he said, “We don’t expect customers to visit all by themselves as they do, for example, at Interlift. So, we invited the regional customers to come by.”

U.S. Partner Country Surpasses Expectations

Dieter Rieger with the latest Ziehl-Abegg product

German companies export more to the U.S. (EUR114 billion [US$128.6 billion]) than the other way around (EUR60 billion [US$67.6 billion]). Being a partner country of Hanover Fair 2016, U.S. companies hoped for an export surge. With approximately 650 exhibitors, Germany, China and the U.S. were the top three nations presenting their goods and services. The 465 U.S. exhibitors dealt mainly with the digitalization of production — 60 with innovative energy technologies. Some of them gathered in “TechnologyPavilions,” such as “Research & Technology,” with almost 20 exhibitors, including Georgia Tech; the Massachusetts Institute of Continued

Technology; the University of California, Los Angeles; and the National Institute of Standards and Technology. Others, from U.S. states such as Florida and Texas, and cities such as Chicago and Los Angeles, used the common booths of these regions. Due to the terror attacks in Brussels, many single U.S. companies downsized their appearance. Both U.S. elevator companies on the preliminary list of exhibitors in February were not present. For the first time ever, a U.S. president opened the Hanover Fair. On Sunday evening, President Barack Obama and German Chancellor Dr. Angela Merkel attended the opening ceremony in the Hanover Congress Centrum. Obama’s topic predominately dealt with the Transatlantic Trade and Investment Partnership (T-TIP). On Monday morning, both leaders took a 2-hr. tour together to visit several U.S. and German exhibitors. Security during these times was extremely tight.

T-TIP aims to create the world’s largest free-trade zone with 800 million people on both sides of the Atlantic Ocean. Since July 2013, there have been 12 negotiations. Talks behind the scenes at the fair pushed toward finishing the trade deal in 2016 from the U.S. side. At the same time, in front of the fairgrounds and in Hanover, about 35,000 people demonstrated against T-TIP. They fear it would result in sinking prices in the agricultural sector, and reduced standards in food quality and consumer protection. A German study in May asked for the opinion of the building industry. Approximately 60% of interviewees expected no or nearly no impact of the trade deal on their companies.

Are New Industrial Trends Reaching the Elevator Industry? Four trends were presented at the fair: integrated energy, additive manufacturing, predictive maintenance and workforce development. Two of these dealt with elevator specifics.

Internet of Things platform. Eric DeShazer, Product Lifecycle Management, said that, in the future, elevators will “communicate” with service technicians. For example, by counting the opening of doors, the system calculates the number of trips. Using algorithms on cloud big data, it then predicts when repairs or maintenance is needed, and service staff are informed. MAX cuts downtime in half and increases safety and availability. During the 18-month introductory phase, mainly in the U.S., Germany and Spain, the new system will connect approximately 180,000 units. Before the official fair opening, Otis President Philippe Delpech and MS CEO Satya Nadella invited the media to a briefing at the MS booth. They discussed an enhanced strategic alliance using MS technology for smart buildings to save energy and raise the productivity of elevators.

Sustainability For the first time, innovative combined-heat-and-power (CHP) units, with 93% efficiency and 50 to 550 kW for singular electricity supply, were offered in the fair catalog. Inge Maltz-Dethlefs, Sokratherm sales engineer for Northern Germany, said, “They can help to span the time of a grid failure or deliver electricity in remote places.” The next Hanover Fair will take place on April 24-28, 2017. Undine Stricker-Berghoff was the managing director of VFA-Interlift e.V. in Hamburg, Germany.

Focus on Safety and Inspection

Best Bureaucrat Miami-Dade County has a chief elevator inspector it won’t want to lose in Michael A. Chavez.

by Hanno van der Bijl In 2006, an elderly Miami couple in their 80s were stranded in their apartment. The lady was battling cancer and could not get to her doctor, because the elevator in their building was broken. The shaft was on the outside, connected to the building via a breezeway. So, they called for help. “Help Me Howard” with Patrick Fraser of WSVN-TV, a local Miami television station, contacted Chief Elevator Inspector for MiamiDade County Michael A. Chavez on their behalf. Chavez went to take a look at the elevator. It was his day off. When he got there, he saw that the elevator door was rusted through, and the guide on the bottom was missing. He recalls, “I kind of chewed on the elevator company for not coming up with an innovative idea of splicing on a piece of metal temporarily until they could get the permanent door built.” It was not a fire-rated door, so this was a feasible solution. The company

took his advice and got the elevator running that day. The lady could now go see her doctor. A couple years later, Miami New Times picked up the story and awarded Chavez with the “Best Bureaucrat” award. Chavez laughs at the thought, “I didn’t know whether to be complimented or insulted, because I don’t normally view ‘bureaucrat’ as a good word. But I guess that’s what I am.” Chavez credits his staff for actually communicating with him and moving on that case before WSVN-TV had contacted him. “It really doesn’t matter if it’s the citizen calling or someone else,” Chavez says. “We deal with it with the same expediency.”

Battling the Race to the Bottom

Chavez began his career straight out of college as an Otis mechanic in July 1972 when he was 22 years old. He had studied at Miami Dade College and Florida Atlantic University. He transitioned into sales in the late 1970s, and, for Continued

Here, he was instrumental in putting together the verticaltransportation system for Providence Hospital. In 1985, he moved back home to serve as Miami-Dade County’s elevator engineer until he became its chief elevator inspector and manager of the Office of Elevator Safety in 2002. In 1993, his office received an award from the National Association of Counties for an elevator contract-management system it had designed and set up. On its 125th anniversary in 2009, the American Society of Mechanical Engineers (ASME) recognized Chavez for his service Chavez with the love of his life, Robin Webb, at a Christmas party last year. Webb previously worked as the Miami-Dade to the Code and Standards County Procurement Officer and had been assigned to the elevator maintenance contracts, over which Chavez is the Committee.

examine them. “Keeping those records on a computer system in the office doesn’t do anybody any good unless someone can access it.� But Chavez is neither anti-technology, nor nostalgic for the past. He believes virtual testing of equipment can be helpful if the results can be reviewed: “I see the computerization of maintenance and performing some functions remotely through computer systems is probably going to be the technological leap that will enable companies to do a better job of maintenance, I think.� This will still be a challenge to implement, because some jurisdictions do not allow for the privatization of inspections, and the trust issue of “sharing screens� would have to be dealt with on an information-technology level. “There’s no substitute for having hands on and eyes on,� Chavez says with a knowing chuckle. He maintains escalators and moving walks, for example, should not be virtually tested. “There is no one simple solution,� he says. “It’s going to be a complex thing to resolve a lot of these issues.�

Safety, First and Last

The mission of Chavez’s Office of Elevator Safety reads, “Safety is the last word in our name but is first in our actions, and is the core of what we do.� Chavez’s dedication to safety is reflected in his heroes, George Gibson and Bob Shepherd. Both men are dedicated to the industry and take safety seriously. Coupled with his passion for safety is Chavez’s deep respect for both formal and informal education. He advises young people in the industry to “get an education and apply it to this field. Do the best you can and try to learn as much as you can from the older generation before they leave the industry.� This is critical when it

comes to repairing equipment. Elevator technology has made for lighter, more energy-efficient units, but planned obsolescence has crept into an industry that once prided itself on making elevators that lasted longer than the buildings they serviced. Now, equipment is designed to be replaced, not repaired, when something breaks. Chavez says the knowledge to replace parts on old equipment, such as oil-bath sleeve bearings (which have been replaced with roller bearings), has been mostly lost with the older generation. “It’s just gonna be a challenge for young people to learn the business,� he says. “It’s been very rewarding for me all these years. But, I took the time to learn the code and learn as much as I could from the guys who were willing to teach it.�

The Future Looking to the future, Chavez says he will probably open a consulting company when he retires from the county next year. As one of three remaining siblings, “I’m the only one in the family still working,â€? he says with a laugh. Chavez enjoys his job very much. His technical and professional approach is balanced by a personal concern for the welfare of the citizens of Miami-Dade County. When Miami New Times made its own call concerning the elevators in a pair of condominium towers in 2008, it found Chavez “candid, responsive, and, apparently, personally troubled by the report.â€? Reflecting on his own work, he says the most rewarding aspect is to see people benefit from his efforts. “The thanks is really all the gift that we need,â€? he says. If Chavez is the best bureaucrat, what kind of consultant will he make?   đ&#x;Œ?

Focus on Safety and Inspection

Breakthrough in Safe and Cost-Effective Elevator Hoistway Control Together, APS and iDiscovery provide an array of benefits.

by Stephan Rohr This paper was presented at Madrid 2016, the International Congress on Vertical Transportation Technologies, and first published in IAEE book Elevator Technology 21, edited by A. Lustig. It is a reprint with permission from the International Association of Elevator Engineers (website: www.elevcon. com). The century-old elevator hoistway safety control system has had its day. More and more safety-related functions are necessary to maintain the level of safety, while more features for convenience, maintenance and premaintenance are additionally installed. The contactless, very robust and precise absolute positioning system (APS), in combination with the position supervisor unit (iDiscovery), takes over all safety-relevant functions in the hoistway and triggers a motor brake via the safety chain, or directly using the electric safety gear. Detection of overspeed or unintended car movement, as well as pre-opening of doors, leveling and releveling with open doors, and retardation control are covered by iDiscovery. Virtual limit switches, virtual inspection limit switches and virtual shelter spaces are all covered by iDiscovery. APS and iDiscovery, in combination, significantly reduce the cost and complexity of elevator equipment, as well as installation time.

Introduction What is going on in different technology branches? In terms of automation technology, a new era has begun. It is called “Industry 4.0.� Sensors are getting more intelligent and can

114 • September 2016

calibrate themselves and trigger events in case of abnormalities. Control systems are getting more features for pre-maintenance to supervise themselves or increase efficiency. Looking at the automobile industry, trucks are using steer-by-wire technology, changing from hydraulic to electric systems. Cars learn to communicate with other cars to help prevent collisions and avoid traffic jams. By comparison, looking at the elevator industry might suggest it is a big, old dinosaur using contactor technology and electric circuits to fulfill codes and standards. There is, of course, a reason for that. The past has proved that this technology is reliable and safe. Therefore, a change to new technology, which has yet to be proven by the market, needs to be as reliable as the technology currently in use, and needs to be as simple for installation and maintenance that technicians can handle it with the same precision and care as they can the proven technology. The task of an elevator is very simple. It has to vertically transport a person safely, quickly and without any interruptions, and it needs to be available 24/7. Furthermore, if unexpected events like power breakdown or loss of traction occur, an elevator must take care that no unsafe situation for the passenger can result. The proposal is to use an APS in combination with iDiscovery to separate the safety-related functionality and the travel-related functionality. This means that a safety control supervises the hoistway in a safe manner to stop the elevator should any unsafe condition arise, and generate status information for the elevator control to allow easy and more efficient maintenance, pre-maintenance and comfort travel.

Figure 1: iDiscovery and APS

Functionality of iDiscovery If intelligent sensors are introduced, the cost increases if no other tradeoffs are possible. A mechanical contact is still one of the safest and most cost-efficient solutions for reading back information of, for example, a door contact. There must be other tradeoffs, which allow a reduction in cost and complexity: ♦♦ Door circuit (car and shaft door) ♦♦ Speed governor (tensioning device, speed governor, rope and safety gear) ♦♦ Retardation control (standard buffers are replaced by reduced buffers, safety switches and a travel pattern control device) ♦♦ Inspection (recall panel, inspection control pit and car, and mechanical installations to protect the technician) The above-mentioned hardware needs to be replaced by electronic means to gain a greater system benefit. Figure 1 shows iDiscovery in combination with the APS. APS produces contactless Safety Integrity Level 3-rated position and velocity information from the code tape, which is mounted in the elevator shaft. This information is transmitted to iDiscovery, which processes the position and velocity information together with the other shaft information to ensure a safe shaft environment for the passengers, as well as the technicians. What is meant by shaft information? Figure 2 shows the elevator car together with three shaft doors and the “virtual” inspection and extended inspection limits. In the gray-dotted box, the virtual limit switches are shown, the positions of which are stored in the iDiscovery by safe means and are always monitored. The

116 • September 2016

Figure 2: Overview of the virtual switches in an elevator shaft

functionality is briefly explained immediately below the figure, and, more precisely, in the following sections.

Door Circuit The most cost-effective solution for monitoring the door status is a mechanical contact. There is no other solution available on the market yet, which comes within the cost range of a pure mechanical contact. In the case of an express elevator with a long travel distance and few floors to service, or an elevator system with two cars in one shaft, where two virtual door circuits are needed, or such a system requiring more than two virtual door circuits, the complexity can be reduced if intelligent hoistway and car door contacts are used. The reduction of electric complexity means also that system reliability is increased, which leads to a cost benefit due to reduced maintenance. EN 81-20: describes automatic bridging in the case of pre-opening doors. The iDiscovery bridges a shaft door automatically within the door zone if it is

commanded to do so by the elevator control and if the speed limit and position of the car are within the given boundaries. EN 81-20: and 81-2: require that bridging of the car and shaft doors is allowed in inspection mode to avoid the use of bridging cables, which can be easily forgotten in an elevator system and lead to an unsafe situation. The iDiscovery has separate door circuits for the shaft and car doors. If the car is operated in normal mode, each car door and shaft door movement is supervised by iDiscovery, which ensures the shaft and car-door safety chains operate as they should. Any unauthorized bridging of a shaft or car door will be detected during normal operation. Pre-opening of doors and releveling of the car are supervised in each door zone to ensure: ♦♦ Bridging commanded by the control and car is within the right door zone ♦♦ The speed is within pre-opening or releveling limits

♦♦ No unintended car movement can occur (in accordance with EN 81-20:6.3.13) The customer can choose if this is combined with an A3-certified motor brake, with an electronic safety gear (eSafety) or with Figure 3: Door operation indicators the electric pre-trigger signal of a standard speed governor. The iDiscovery guarantees a deterministic reaction time, which can be used for the unintended-car-movement (UCM) calculation. Figure 3 shows the door operation indicators together with the system operation indicators of the iDiscovery: ♦♦ ERR: This means that a system error has occurred, which may be reset by switching the iDiscovery off and on again. ♦♦ APS: If lit or flashing, there is no communication with the APS or the APS is not mounted accordingly and, therefore, no absolute position is available. ♦♦ OS: Overspeed has been detected. ♦♦ RC: Retardation control has occurred. ♦♦ UCM: UCM has occurred. ♦♦ RST: Reset button to switch back to normal operation. ♦♦ FLT: Final limit top has been reached. ♦♦ DZ, UP, LEVEL, DOWN: Indicates firstly if the car is in the door zone (DZ), if it is leveled (Level) or if it is above (Up) or below (Down) the door zone ♦♦ DZ: Door zone over-bridging activated. ♦♦ FLB: Final limit bottom reached. The status information can also be read via proprietary CAN or CANopen (DS417) by the elevator control.

Retardation Control At the upper and lower ends of the elevator shaft, the iDiscovery always checks if the travel speed and deceleration are below the maximum allowed. If this is not the case, firstly, the safety chain is opened to brake using the motor brake, and, secondly, the safety gear is triggered.


Figure 4: Maximum travel curve for retardation control

This functionality is also used in accordance with reduced buffer stroke (EN 81-20: The maximum possible speed limit curves are shown in Figure 4. If the car, for some reason, is accelerated to reach these limits, the safety chain is first opened (black curve), and the safety gear is then triggered (gray curve) to avoid the car hitting the buffer with more kinetic energy than allowed.

Speed Governor The conventional speed governor, as shown in Figure 5, has proven its reliability over many years. With old elevator installations, the requirements of the overspeed governor are to stop at a predefined overspeed and activate the safety gear by means of a rope. With today’s installations, it is useful to have an adapted stopping speed for UCM. If the speed within a door zone exceeds 0.8 mps or the end of a door zone is approached too quickly, the safety gear is triggered if, in leveling or releveling mode, the supervised speed can be lowered to 0.3 mps. If a maximum acceleration occurs when leveling with open doors, the UCM can be detected even earlier. If inspection mode is switched on and the elevator is commanded into the inspection shelter spaces (if the elevator travels over the inspection or extended inspection limits), the safety chain is first opened to activate an A3-certified motor brake. If the car travels 50 mm beyond this limit, the safety gear is activated to protect the technician from collision. A conventional speed governor cannot handle the described modes accordingly, because it is built for one (or, maximum, two) different speeds without any position information. These

Figure 5: Conventional speed governor (Source: Internet Wikipedia)

Figure 6: Cobianchi PC24GO electric activated safety gear

functions can be substituted if the conventional speed governor is replaced by an APS and iDiscovery. In this case, the level of safety increases dramatically. The iDiscovery can trigger a conventional speed governor by using the pre-trigger signal of the speed governor or by directly triggering any electronic safety gear. Figure 6 shows the Cobianchi PC24GO electronic safety gear. The diagram in Figure 7 shows the triggering of the safety gear. The top diagram shows position over time, while the second shows speed over time. The safety gear is triggered by iDiscovery at 2 mps. The overall reaction time is about 117 ms. The iDiscovery has been configured to 50 ms of reaction time. The reaction time needs to be chosen very Continued • September 2016

Figure 7: Example of an electronic safety gear triggered by the iDiscovery at 2 mps (Source: Cobianchi)

carefully. If it is too short, robustness is lost, and the safety gear may be activated unexpectedly. If the reaction time has been set at over 100 mps, the system itself may be very robust against unexpected activation. However, the time where the car is still being accelerated becomes too long for adequate system behavior. Tests showed that the trigger time should be between 50 ms and 100 ms. The maximum speed, in this case with an activation speed of 2.0 mps, is 3.15 mps.

Inspection The EN 81-20: and 81-20: standards feature a big change in the function of recall panels and inspection controls. If recall panels and inspection controls are connected to iDiscovery, it prioritizes the use of recall and inspection in accordance with the standard. Independent of the inspection panel (car or pit) and access-door switches (headroom or pit), iDiscovery switches on the virtual inspection limits and extended inspection limits to ensure enough shelter clearance and prevent unsafe situations for the service technician. The signaling of the inspection module is shown in Figure 7. The signaling is: ♦♦ RP: Recall panel switched on. ♦♦ CIC: Car inspection control switched on. ♦♦ PIC: Pit inspection control switched on. ♦♦ ST: Headroom-access door top has been opened. ♦♦ SB: Pit-access door bottom has been opened. ♦♦ ILT: Inspection limit top activated. ♦♦ ILB: Inspection limit bottom activated. ♦♦ ILTE: Inspection limit top extended activated. ♦♦ ILBE: Inspection limit bottom extended activated. Even if the car has broken one of the virtual limits, and the iDiscovery is reset, it prevents the car from being moved further in the wrong direction by keeping the safety chain open, even in the event of a reset. Clear visualization helps the technician easily understand which part of the safety chain may be causing the trouble, without the need for bridge safety chain contacts. This simplifies troubleshooting and avoids unsafe situations.

on software with Industry 4.0 functionality, algorithms and customer features. There is a clear separation of safety-relevant data processing and non-safety-relevant data processing. With its modularity, the iDiscovery system can also be used for high-rise installations in combination with a door safety chain with intelligent door contacts. The overall safety functionality stays the same and makes it simple for the technician to install and maintain an iDiscovery. The author regards this as key to Figure 8: Inspection making a system safe, and means having a clear operation of the and simple system and installation process. iDiscovery This applies to each elevator installation, whether it is low-rise or high-rise. Stephan Rohr has been employed as senior product manager at CEDES AG since November 2015. He previously spent six years with thyssenkrupp Elevator Innovation GmbH, where he managed the frequency-inverter department before taking over management of the product development center Central/Eastern/Northern Europe in 2010. Prior to entering the elevator industry, he developed control strategies for frequency inverters for the solar energy and mobile power industries. His current focus is on innovative solutions for shaft information systems and SIL-3-rated devices.

Results The iDiscovery has been developed on a modular basis. Several test installations show that modularity is key.

Focus on Safety and Inspection

Speeding Up Elevator Inspections and Reporting Introducing a timesaving mobile app years in the making by Sanjay Kamani Improving operations is an evergreen topic. Several years ago, proposed a common electronic-data management platform (ELEVATOR WORLD, September 2012). The idea was to modernize operations, while ensuring code compliance. Since the industry still struggles with slow inspections and late reports, UpVate Anywhere, a web-based mobile app, has been developed by a company of the same name. Per our testing in a 44-elevator tower, it has led to 33% less time spent in a building and 50% less time writing up the report.  

Target the Delays The app has two purposes. The first is to reduce the amount of time spent onsite (taking photos, making notes, etc.). The second is to reduce the amount of time spent generating a report that is correct and makes good sense. Today, digital cameras, laptops and tablets have begun to displace printed forms and written notes. New technologies often remain separate from each other and the reporting process. That lack of continuity builds delays into what already is a limited timeframe. Those delays accumulate onsite, as the clock begins ticking upon arrival. They also impact the write-up phase. Reports are often already backlogged. What inspectors need is a way to collect data that makes it easier for them or their teammates to write up later. The following is a hypothetical walkthrough of an inspection with a mobile app that streamlines the process.

How It Works Before the day starts, you will have first created a list of inspection sites. This list includes the names of buildings, property managers, number of stories, etc. Upon arriving at the first site, click on the appropriate inspection. Once inside, you can add an elevator bank, car number, government identification (if available) and device type. You can also add a service company and other notes. Next, a checklist is selected for the specific inspection you are about to perform. This is done via a dropdown of preestablished custom checklists. Clicking on “Start” takes you to

“Bank 1” and allows you to select your location. This could be the machine room, hoistway, lobby, pit or car. In a designated location, you can add data, record audio or take a picture. You might photograph worn ropes or missing guards, or make a voice note associated with the images. You can view the image, edit tags, take another photo, delete the photo and delete audio. As you move through your inspection, take more pictures and add voice notes. When done, you can view inspections or add a new one. The “View” page gives you the option to continue or delete an inspection. Only after the app has synchronized data with the online site can you delete it from your phone. 

New technologies often remain separate from each other and the reporting process. That lack of continuity builds delays into what already is a limited timeframe. Compiling the Report On the website, you will see a list of all buildings with synchronized data. By clicking on “View,” you can see each location that contains an image and associated voice note. A voice-transcription feature can turn that recording into a written note, or you may do so manually. You can crop, rotate and annotate the images, as well. From the web app, you can export the file into Microsoft® PowerPoint®, then manipulate the downloaded file. You can also copy and paste into a Microsoft Word® document or whatever format you use for reporting. Everything you need to write the report is in one place. Sharing the report is the next step. We are enhancing the web app to allow the user to invite clients to view the inspection Continued

results. Adding custom checklists, which can be based upon each local authority’s requirements, makes the app even more complete.

Saving Time, Today The only things required are a smartphone and downloaded app, paired with another app in the cloud. The wide variety of formats makes it impractical to automate the entire production cycle. But, even without custom report creation, this kind of tool can deliver impressive results. An end-to-end system that integrates with many stakeholders remains an attractive vision. Applying Internet of Things (IoT) technologies could lead to more efficiencies (EW, September 2014). However, sometimes the perfect is the enemy of the good. Saving time both onsite and in reporting is possible today with a single mobile app. Sanjay Kamani has more than 27 years of elevator-industry experience with a specialty in data collection, analysis and process management.

Why PESSRAL Is Not PESS Important safety ramifications in European standards applications

by Tijmen Molema This paper was presented at Madrid 2016, the International Congress on Vertical Transportation Technologies, and first published in IAEE book Elevator Technology 21, edited by A. Lustig. It is a reprint with permission from the International Association of Elevator (website: www.elevcon. Engineers com). The lift industry is quite old fashioned in electric/electronic/programmable electronic (E/E/PE) safety: it used the electric safety chain for more than 30 years. However, since the EN 81-1/2 A1: 2005 amendment, the standard allows use of The calculation is the electronics theoretical basis; it gives programmable for safety systems (PESS). insight into the weakest Also, when the code points of the system and committee decided to implement a subset of the proves that the system is leading norm (IEC 61508) into EN 81 in order to safe enough. decrease the difficulty and increase the implementation speed, Programmable Electronic Systems in Safety Related Applications for Lifts (PESSRAL) was born. However, due to cherry picking and skipping the basics, the old and even the newest code (EN 81-20/50) makes it possible to create unsafe systems. Where are the potential risks?

Leading Norm The IEC 61508 itself consists of seven different pieces with a total of more than 500 pages. It describes the complete path to follow when creating an E/E/PE safety device. It contains calculations, assumptions, design strategies, risk analyses and descriptions of

quality systems. It results in a safety integrity level (SIL), which is a mathematical number expressing the safety of the system. All of this documentation is needed to end up in a safe system. In contrast, EN 81-20/50 uses 11 pages and claims to be a full package.

Systematic Capability The entire process flow for making a PESS is described in a separate part of the standard, 61508-1. By a clear way of working and project management, we try to minimize systematic failures in a system. There are clear demands, and this results in a systematic capability (SC) value. Techniques that can be used are, e.g., project management, documentation, structured design and modularization, as well as the SC, as these techniques are not demanded or described in EN 81-20. Projects without proper management can contain major mistakes, and these are hard to spot.

Risk Analyses For safety software, SIL is used to measure safety. It is a mathematical number expressing the safety of the system. For example: SIL 3 has an average chance of failure between 10-9 and 10-8 or 10-5 to 10-4 an hour, depending on the demanded rate. Normally, you have to perform a risk analyses in order to determine the needed SIL rate. EN 81-1/2+A3 and EN 81-20/50 have already performed this risk analysis in it and ask for SIL ratings. This way, there is no need for a risk analysis, which creates uniformity in the systems of competitors. However, a risk analysis gives insight into the project and influences the design. This is mandatory in IEC 61508 procedure, but not in EN 81-1/2 and EN 81-20. Continued

Demand So, a SIL level is available, but it is not clear by the standard if we’re working in high or low demand. The difference in demand rate between these, however, is exactly a factor of 10.000 failures/hour. Low demand is explained in IEC 61508-4 as “where the safety function is only performed on demand, in order to transfer the Equipment under Control (EUC) into a specified safe state, and where the frequency of demands is no greater than one per year.” For a lift, we do not use the over speed governor more than once a year, so is it, then, low demand? This is necessary to know, because it gives a difference in the calculated safety by a factor of 10.000. It is not plain set in the standard. However, the IEC-62061 states that machines shall fulfill high demand. Most of the certifying organizations are following this guideline. Unfortunately, it is not set plainly in EN 81-20.

Safe Failure Fraction When building a SIL 3 system, the relevant tables in EN 81-1/2+A3 and EN 81-50 mandate a double-channel system. The main idea of this is “when one channel fails, the other channel will put the system to a safe state.” IEC 61508 has the same principles, but there are some major discrepancies. IEC 61508 describes the model of Safe Failure Fraction (SFF): the fraction of failures which is safe and which is dangerous. For components where the failure mode cannot be predicted (like CPUs and other complex systems), the demands are set higher. Here, diagnostic software also increases the SFF. Due to the fact that EN 81-20/50 demands a twochannel system for SIL 3, it excludes the use of a totally failsafe (SFF = 100%) one-channel system and makes it possible to create a fail-unsafe (SFF < 90%) system. If every possible fault in a channel is directly dangerous (SFF = 0%), and if the fault remains undetected, a second fault causes an unsafe system. This way, PESSRAL solutions can be less safe than the fault tree analyses present in EN 81-20.

Common Cause Due to not performing a risk analysis and the demand for two channels for SIL 3, a new difficulty occurs. By demanding

two channels without further specification, it becomes possible to build two identical channels. These identical channels introduce the risk to fail at the same time due to the same error (common cause). Typical errors are a slightly to very low supply voltage, design faults inside a CPU or temperature. When working with multiple channels, the common-cause errors are the largest part of the total. You can compare it with throwing a die. If by throwing a one, you will lose, your chance of losing is exactly one in six. To decrease this chance of losing, you can add another die. Now, you need two ones to lose the game. When calculating the chance of losing, we use: 1/6 * 1/6 = 1/36. Now, we introduce a common-cause fault in this “system,” a fault that influences both channels (the dice). Due Worldwide to the fact that information the number “6” is represented on about lift the other side of catastrophes do the die, and for not exist related painting six dots, we need slightly to this topic. more paint. More paint also means more weight, and two opposite sides on a die always give a total of seven. Due to this faulty design, the chance of throwing a one is bigger than that of throwing other numbers. The chance of a double one is also bigger than the chance of another double combination. If I have a 5% more chance of throwing two ones, the system is 5% less safe than 1/36: we need to add 1/120 to the 1/36. For this system, the impact is relatively small. However, the fault chance of a PESS channel is a lot smaller: for example, 10-9. Doing the same calculations, the twochannel system has a 10-9 * 10^-9 = 10^-18 chance of failing. Now, we add the 5% common cause: 5 * 10-11. We can see clearly that the common-cause part is much bigger than the single-channel faults. If we have smaller-failing chances in channels, the common cause will become more important and be the dominant part of the safety calculations, as well as the real safety. EN 81 does not tackle this problem; no techniques for common-cause avoidance are described or calculated.

Diagnostic Techniques EN 81-20 cherry picks a number of techniques and states them as mandatory. There is no calculation needed anymore. (EN 81-50 states that IEC 61508-6, which explains the calculations, is not needed for understanding.) IEC 61508 gives a large number of options; the most suitable technique can be chosen for the system. It can happen that completely irrelevant techniques are demanded, where other techniques are quite more useful. For example: there are no demands for sensors in the lift standard, but when we use a complex logic programmable device (CLPD), there are still demands for RAM checks and watchdogs; this is not right, according to IEC 61508. Here, we cannot check if our diagnostics are good enough. Normally, diagnostic coverage (DC) has a direct influence on the safe failure fraction (SFF), and so on, the entire safety calculation of the system.

Calculations The backbone of IEC 61508 is the underlying calculations. By looking at all components’ failure in time (FIT) rates and design, a calculation of the chance of failure can be made. The calculated numbers should be in line with the SIL rate. Failure modes and effects analysis on components and DC in order to improve the SFF ends up in a safer system. IEC 61508 has demands on the SFF which need to be met. The calculation is the theoretical basis; it gives insight into the weakest points of the system and proves that the system is safe enough. This calculation is not needed for EN 81; by fulfilling all demands, the requirements are met. These demands describe techniques only but do not give any numbers. There is no check if the system is “safe enough,” so it is possible to end up with a mathematically unsafe system. For example: two really bad relays can be used in parallel. When they fail every 10 times, they will both fail at the same time every 100 times (excluding common cause). It still fulfills EN 81-20 (double channel with diagnostics): it can be detected that both relays are failing. However, at this point, it can no longer be acted upon. When we calculate the failure rates for the system with IEC 61508, we will directly find that the relays are not Continued

good enough for this system: the FIT values will be devastating for the productfailure-per-hour figure. Due to the calculation, bad components are filtered out.

Testing Every system needs testing after development: there are always unforeseen problems that are filtered out during the test phase. Of course, a PESSRAL system will be tested, but which test strategy is the proper one? Most of the industry has no practical experience with safety software, and there are no test strategies mandatory or even mentioned in the standard. The most commonly known test method is black/white box testing. This basic way of screening a system is usable for both electric and mechanical systems. When creating PESS, the system is a full black box. However, IEC 61508 can also ask for traceability of the requirements, full modeling, software simulation and performance testing. Also, there is no test procedure or awareness for common-cause faults in the lift norm.

Proof Test Interval Again, the lifetime of a system is not considered. Due to the fact that periodic inspection on PESS systems is almost impossible, a lifetime must be specified. Diagnostics in the system also cannot detect every possible fault; the DC is always smaller than 100%. Normally, PESS systems have a “proof test interval” to detect the normally undetected errors. EN 81 does not require this. This allows a system to build up an endless amount of errors and gives the possibility of ending up with a dangerous fault.

Discussion At this moment, only a small amount of lifts work with PESS. For the ones that work, there are no major failures yet. PESS application has been possible since the first amendment of EN 81-1/2 in 2005. We do not know how many installations are in the field today, so we cannot determine why there were no failures. There are some possible explanations that can explain the fact that we did not have any accidents: 1) When making something revolutionary, a company must be absolutely sure it is safe. Otherwise, the product will not be accepted in the market by the customer. For PESSRAL, most lift companies want to be absolutely sure that it still works after several years, so endurance tests will probably be done. This is a powerful testing method. 2) There are not many PESSRAL systems in the world: most lifts have a long lifetime, and controls are not regularly changed. Also, the development of PESSRAL has just started: there are not many PESSRAL systems on the market. Most of them are still in development. 3) The major certification bodies also perform tests on PESS systems. They have their own demands for testing or will ask for a calculation. Certification bodies also want safe systems, and most of them know how to perform the tests properly. 4) There is no guideline for reporting crashes, and we cannot be sure that we will hear about all crashes in the world, especially reports that include the cause. The biggest problems of these possible explanations are the fact that they are not mandatory: there are no demands on test time, and there is no requirement for


experience in PESS for Notified Bodies. Also, worldwide information about lift catastrophes do not exist related to this topic.

The only way to check the system now is by testing, but testing strategies are not described. Conclusion PESSRAL is not PESS, and this is not only due to the absence of a lot of background information. The entire mathematical backbone is gone, so we cannot calculate if the chance of failure of the system is right. This has a huge impact on the common-cause faults. These are the most dangerous faults for a double-channel system. Also, the channels themselves can be made out of unsafe components. The only way to check the system now is by testing, but testing strategies are not described. As of the time of this writing, there have been no fatal accidents yet. However, we cannot explain why they didn’t happen or predict that they won’t happen. In the end, it is possible to build unsafe systems with the rules of PESSRAL. For now, we can only hope that lifts will stay safe; for the future, we need EN 81-20 to change as quickly as possible. Tijmen Molema is a certified product specialist for Liftinstituut.

Something Has to Give This introspective Readers Platform addresses the critical topics of maintenance contracts and route overloads in the U.S. by Justin Robert This article is written from my perspective as an International Union of Elevator Constructors maintenance mechanic. I began working in the elevator business in the early 1980s, initially alongside my father in construction. My father had been in the elevator trade since the early 1950s. He loved this trade Back then, it seemed we and always appreciated the had more time to go slow, friends he made while part of it. Like many of my think things through, and coworkers, we were second- or third-generation there was much less on elevator tradesmen, and in our minds as we the long run, I believe the performed our daily relationships we forged ultimately characterized how responsibilities. we cooperated in the field. When I became a mechanic in the mid 1980s, I was given the opportunity to work a maintenance route consisting of 40 units, all Westinghouse, which gave me the time to learn many of the ins and outs of the trade and specific equipment. Over time, basic problems became much easier to fix, and as for more difficult issues, there were always experienced mechanics close by who were available and willing to assist — not only informing me how to do each job, but how to do it safely, carefully and in a way that was best for my well-being, the customer interest and the company’s bottom line. Safety was, of course, a legitimate concern, but not in the way it is today, possibly due to the increasing frequency of accidents. Back then, it seemed we had more time to go slow, think things through, and there was much less on our minds as we performed our daily responsibilities. Every task and every tool was something with which the worker would be

familiar. Working in pairs and with a large team of people involved, there was a large amount of camaraderie and cooperation in the work environment. Our supervisors consisted of many older, experienced men who were, perhaps, former union mechanics who had performed the job for many years. These supervisors oversaw their workers from a mechanic’s perspective, which certainly helped detail how the position was to be managed. Today’s mechanics meet considerably more challenges. Companies appoint more young supervisors now, typically just removed from college, who attempt to manage the tradesmen with little to no elevator or industry knowledge. Due to labor shortages, help is scarcely available, and the opportunity to sit with a comrade and talk shop is difficult to come across. We maintain many different types of equipment, which makes it more difficult to master. Customers are becoming upset over longer waits for service and increasingly more billable charges. Commutes for workers are worse than ever. The companies scrutinize every working hour, meanwhile searching for every way to avoid us from getting a hangnail, and with more rules, the job is becoming virtually impossible to fulfill, and tasks are becoming harder to complete in a timely manner — with threats of losing our job if we cannot comply. To be fair, I understand that the amount our companies receive per maintenance contract hasn’t changed much in 20 years, yet labor prices continue to rise. Some research into profit percentage shows this to be a healthy, recessionfree industry. Return-on-investment margins and greed for bigger profits go hand in hand. The Continued

Today’s mechanics meet considerably more challenges. Companies appoint more young supervisors now, typically just removed from college, who attempt to manage the tradesmen with little to no elevator or industry knowledge. competitive nature between OEMs is the primary reason for stagnant contract prices. The desire to cut each other has allowed small independents to thrive. It has forced their hands to cut corners at every turn and find new ways to bill charges. The best way they see to cut corners is in labor. As mentioned before, there are fewer and fewer persons with experience, and the union employees are aging faster than we are allowed to train new ones. Large companies continue to downsize those who are actually working and communicating with the paying customers. There is no end in sight. In our servicebased industry, few retiring mechanics are replaced, and there are few helpers in training to become new mechanics, as had been the successful recipe for so many years. This pattern has repeated itself over and over for, perhaps, 10 years now. The quality of new installations has deteriorated as the time allowed or specified by companies has dwindled. Although technology has advanced to decrease labor needs, the current pattern of downsizing labor continues, and the results will show through the shrinking customer base and increasing rates of injury and death, despite an influx of extensive safety measures and rules. The next pattern to develop over the next 10 years could potentially cause more accidents to occur with the riding public. Less periodic maintenance being performed and fewer visits to jobs mean more dangerous conditions or things slipping through the cracks. Major repairs

like cable replacements or machine/motor work is put off indefinitely unless units are shut down. Each year, a route mechanic works about 230 days, including holidays and vacations. Many routes have 200-300 units. The workload continues to increase due to the fact that there are more major repairs. Inspections and call-backs all take priority over actual maintenance. The actual time remaining for preventive maintenance averages one day a year for each unit, which is exactly what the companies want for hydraulics (yearly visits). At some point, something has to give. I sincerely hope this industry/trade continues to thrive for both our union and the signature companies, and that elevators continue to be one of the safest forms of travel. Toward that effort, I’d like to offer some advice to property managers or anyone else in charge of buildings with elevators: 1) Read your contract carefully and understand what it specifically covers. 2) Do not necessarily accept the lowest bidder. 3) Avoid ambiguous contract terminology, such as “periodic maintenance inspection.” Instead, define weekly or monthly visits (for traction inspections), or monthly or quarterly visits (for hydraulics). 4) Hold the company to its responsibilities defined in its contract. 5) Get to know and have a friendly relationship with your maintenance person. 6) Do not wait too long to upgrade your equipment, especially if your equipment has age checks (listed as terms like “obsolete”), as this may imply future additional charges.

The new product reflects — J. Isauro Barrutia, how the industry has changed since Barrutia entered it in the president, EEVI early 1980s. He previously served as managing director for EV Elevator Group, responsible for manufacturing and sales in the North American market. He observes: “The product has evolved substantially. First came the evolution in variable-frequency controls in the early 1980s. Then, we had the other big change, permanent-magnet motors, and lately, the MRL products, which are light and energy efficient, have been desired by many customers. In the past five to seven years, I think all elevator companies would agree, MRL equipment has been the biggest trend. Customers like MRLs since there is no longer a

Complementing its plant, it has a 40-ft.-tall test tower that allows for four stops. When the company started, approximately 90% of the units manufactured were hydraulic, with the remainder traction. Today, that is about 50/50. “Whatever projects used to call for a hydraulic system — basically buildings that are three-four stories — are now opting for MRL equipment,” Barrutia states. The EEVI plant manufactures and installs mostly for customers in North America, Puerto Rico and the Caribbean. The remainder go to the domestic (Mexican) market. EEVI has 15

Cabs for custom jobs are often panoramic, and can be flat, faceted or curved. EEVI manufactures elevators for passenger, freight and hospital use. A particularly challenging modernization project took place at a resort on the island of Aruba (ELEVATOR WORLD, October 2003). Heavy equipment was transported by container ship and plane, and an installation crew was flown in. EEVI has done many comparable, challenging jobs since then. EEVI has found the most challenging part of doing business is keeping up with all the different codes. Barrutia says: â&#x20AC;&#x153;Codes are being updated constantly, and itâ&#x20AC;&#x2122;s a challenge for everybody in the industry to keep up with them. Many states, cities and jurisdictions in North America have different codes. One of these days, we may have one single code, like in Europe, but I doubt it will happen anytime soon.â&#x20AC;? Although most customers are in North America, EEVI has exported products to as far away as Saudi Arabia and is willing to work with any customer, anywhere, on a project.

he Reus, Spain-based Fermator Group has seen phenomenal growth over the past few years. While it had enjoyed much recent expansion and high revenue when ELEVATOR WORLD last covered it in detail (EW, October 2007), it has continued on an upward path and now boasts it is “the largest mono-product manufacturer of automatic doors and spare parts for lifts in the world.” The group includes 1,240 employees led by a management team of 67 and had EUR252 million (US$286.4 million) in consolidated net sales in 2015. It is a global leader in the following segments: new installations for residential, commercial and freight applications, and existing installations for residential and commercial applications. Globally, it boasts nine manufacturing hubs, five distribution centers and 33 authorized distributors. There are also four factories under construction. The company graciously invited all Elevcon 2016 attendees to tour its local plants following the conference, including its headquarters. Your author readily accepted and was well taken care of by Jordi Anguela, Xavier Buesa and Samuel López Barrera. Anguela explained that, per Fermator’s international orientation (serving more than 90 countries), employees in contact with customers must be able to speak the customer’s language, making the company linguistically diverse. In addition to Spain, its production facilities are located in France, Italy, Poland, Greece, India, China and Brazil. Distribution centers are in Turkey, the U.K., Sweden, France and Germany. A family-owned company, Fermator manufactures all kinds of lift doors, except vertical freight doors. It produces operators, landing headers, and doors in round, asymmetric, reduced-width and manual configurations. Its under-driven doors are popular for panoramic elevators. Other components include AC permanent-magnet motors, which it designs, develops and manufactures, and electronic circuits, which it designs and develops. Some models are plug-and-play for modernizations or repairs in which other brands and models are replaced. Continued

The drive between factories was picturesque, full of villages nestled among the olive farmland, vineyards and rolling hills.

Fermator Plant Our first stop was a short drive from Reus to Falset, where the Fermator-branded factory, dubbed “DMT,” is located. More modern (approximately 15 years old) and a bit smaller than the company’s original location in Reus, it only produces what Anguela explained as “commodity doors,” which are usually in the form of very large orders from OEMs. These include the VVF 7 door, which conforms to the new EN 81-20 code. The lack of custom work and design here precludes the need for many office workers — only 15 of the approximately 100 employees here hold office jobs. Though many workers (both permanent and temporary) were constantly busy, the modern system has much automation: specifications come in electronic files, there are four tireless robots that operate 24/7, and all packaging and loading is tracked via a barcode system.

Anguela described the four caged Kawasaki robots as “tireless workers.” Their work queue is added to throughout the day, and they endlessly stamp prepared door panels to precise specifications.

The large Tecnolama plant was built in 1977 and later expanded to produce a larger quantity of custom doors. These have been very popular and comply with required international standards, including EN 81-1/2, ASME A17.1, and fire requirements EN 81-58 and UL 10B, among others. Its fire doors are rated for 1 or 2 hr., depending on customer specifications, and can stop both flame and heat. Approximately 280 people work here, with 80 of those being office workers. Anguela stated the employees pride themselves on having only a 15-manufacturing-day lead time for most types of doors. Workload here is sometimes more sporadic due to the custom, smaller-scale orders, so when they are more busy, up to 10% more workers are hired temporarily. All employees were friendly and were reportedly happy to work for the company in an area where few skilled, high-paying jobs are available. â&#x20AC;&#x153;Many of us say we want to retire from here,â&#x20AC;?

Market Trends

Africa Increasing urbanization and a growing retail sector, particularly in South Africa, present opportunities for vertical-transportation companies. by Shem Oirere, EW Correspondent As urbanization continues in Africa, the continent’s cities strive to address issues, such as the need for more space and energy conservation. These issues, along with a robust retail sector in South Africa, create opportunities for vertical-transportation companies, especially those that manufacture machine-room-less (MRL) elevator systems, a technology elevator companies say that, despite The sector’s future in shortcomings, addresses the Africa looks promising issue of inadequate space, since these systems eliminate if the findings and the need for a machine room. projections of various MRL systems are also said to market researchers and utilize 30%-80% less energy compared to other types of analysts come to pass. solutions.

Decreasing urban space in some of Africa’s cities has created an opportunity for real-estate developers to build taller buildings. Yet, there are property consumers in Africa who prefer low- to mid-rise buildings because of their perceived ease of access by users. Other benefits include safety provisions in case of a fire, likely lower cost compared with taller buildings and more land for other uses, such as warehouses and parking lots. With the issues of space and energy efficiency in the backs of the minds of many real-estate developers and contractors, the sector’s future in Africa looks promising if the findings and projections of various market researchers and analysts come to pass. “In almost all of Africa’s markets, demand for high-quality retail, office and industrial accommodation outstrips supply Kampala, the capital of Uganda; photo courtesy of the Kampala City Council

as international and local occupiers respond to the improving economic outlook,” says a report by multinational professional services firm PricewaterhouseCoopers (PwC).[1] This is particularly true in South Africa, where the real-estate sector continues to grow, fueled by an increasing middle class and massive urbanization. Although the country’s economy grew by 1.3%, down

from 1.5% in 2014 and 2.2% in 2013, the drop did not hamper progress in specific economic sectors, which partly accounts for the steady rise in urban population to an estimated 62% of the country’s 53 million people.[2] PwC notes South Africa’s urban population is expected to reach 70% by 2030, triggering a surge in demand for housing. Further, “pressures of increased

urban density will start to present regeneration opportunities, such as in areas within the Johannesburg Central Business District, where old office buildings are being transformed into residential premises with varying levels of success,” PwC states in a report.[2]

OEMs Are Optimistic about South Africa, the “Gateway to the Sub-Saharan Zone” Mall of Africa opened its doors nearly two years after Otis was awarded a vertical-transportation contract for the 65,000-m2 Matlosana Mall, developed by Abacus Asset Management in Klerksdorp, which has since attracted 145 store operators. Matlosana Mall, owned by Redefine Properties, is equipped with four Otis XO-508 escalators, three FO-VF goods lifts and four Gen2® ReGen lifts. Retail tenants served by Otis units include Checkers, Pick n Pay, Woolworths, Edgars and Foschini. Otis, which last year acquired the South African service arm of thyssenkrupp Elevator, said the four Gen2 ReGen lifts replace old rope technology with “flat, polyurethane-coated steel belts.” This, Otis states, is revolutionizing vertical transportation throughout South Africa. “The energy-efficient system delivers smooth, quiet performance, while offering flexible, space-saving configurations and rapid installation,” Otis notes. Otis’ South African footprint cuts across commercial and residential buildings with installations in two of Africa’s 10 tallest buildings — the 732-ft.-tall Carlton Centre in Johannesburg and 492-ft.-tall South African Reserve Bank in Pretoria. Other Otis installations are at the Chris Hani Baragwanath Hospital in Sowito; Sasol Polymers and Clearwater Mall in Johannesburg; Sandton City in Sandton; and the Golden Acre Shopping Center, Groote Schuur Hospital, Houses of Parliament complex and Ritz Hotel in Cape Town. Although the retail market continues to fuel demand for new building-transportation equipment, South Africa also provides a good market for companies keen on maintenance and modernization, especially for systems in the country’s tall buildings such as Marble Towers in Johannesburg, Pearl Dawn in Umhlanga or the 88 On Field building in Durab. These structures are among the top 10 tallest buildings in Africa. In fact, South Africa is home to at least six of the 10 tallest buildings in Africa, including the continent’s long-reigning champion, the Carlton Centre, owned by the country’s largest transport logistics company Transnet. The Carlton office building, which was designed by Chicago-based Skidmore, Owings & Merrill and constructed by Murray & Roberts, has 23 elevators supplied by Otis. Unlike many Sub-Saharan building-transportation markets, South Africa has continued to attract leading verticaltransportation equipment suppliers in recent years because of the perception the country is a safe investment platform and suitable launching pad for those keen on expanding their African foothold. KONE, Mitsubishi Electric and Schindler are among OEMs that have penetrated this market. Mitsubishi Electric opened an office in Johannesburg in May 2015. In announcing the move, Mitsubishi Electric Europe B.V. President & CEO Yoji Saito said:

148 • September 2016

“South Africa is one of the largest markets on the African continent, benefitting from a well-developed business environment and an established infrastructure. It is the gateway into the Sub-Saharan zone, which, with its growing population, promises strong potential for future growth.” Last year, Schindler described South Africa as the largest elevator and escalator market on the continent, after the company was awarded a contract to supply nine 7000 high-rise elevators with PORT technology, six 5500 elevators and two 9300 AE escalators for the PwC tower in Johannesburg.[11] Overall, Schindler estimates it has supplied 90 units, many of them 5500 elevators and 9300AE escalators for buildings such as Discovery Sandton in Sandton, Umlazi Mega City in Durban, and V&A Grain Silo and Netcare Christiaan Barnard Memorial Hospital in Cape Town.[11] The 2014 acquisition of the South African service business of thyssenkrupp Elevator by Otis points to South Africa’s emerging mergers and acquisitions market in the building transportation industry that gives market players an opportunity to leverage their strengths and grow their market share in the region. According to Segren Reddy, managing director, Otis Southern Africa, the acquisition “will increase our operational footprint, connecting us with new customers and increasing the number of units we maintain and repair.”[12] The South African Reserve Bank in Pretoria boasts an Otis verticaltransportation system; image courtesy of RBSA.

South African property market, fueled by a fast-growing middle class with an average disposable income of US$1,100 a month. The South African Council of Shopping Centres (SACSC) observes the country has the sixth-highest number of shopping centers of any country in the world, boasting almost 2,000 centers with a floor area covering 23 million m2.[3] SACSC President Nomzamo Radebe said retail and retail property are the “most exciting and innovative industries” in South Africa,[4] and the two are playing significant and valuable roles in the country’s economy. This is best illustrated by the emergence of new shopping malls in recent months in many parts of South Africa that have become major consumers of passenger elevators, escalators and moving walks.

According to Urban Studies, which conducts feasibility studies for developers, it is estimated South Africa has 1,785 malls with more than 40% of shopping-center space located in Gauteng province, the country’s most urbanized area and home to South Africa’s largest city, Johannesburg; administrative capital, Pretoria; and two of the largest industrial areas, Midrand and Vanderbijlpark.[5] It is not only major metropolises that are seeing activity. Commercial property management company Broll’s Division Director of Research Elaine Wilson says South Africa is “seeing more and more shopping centers in rural areas and towns, and, in Johannesburg, it is not stopping.”[6] Dirk Prinsloo, managing director of Urban Studies, notes that “people are dusting off old plans that were put on the shelves in 2008 when the recession started. . . and there are other new opportunities [for] people [to] move into the rural areas.”[6] The obsession with modern mall construction, especially in major cities such as Johannesburg, Durban and Pretoria, means brisk business for the numerous players in the South African vertical-transportation market. They include Otis, KONE, United Elevators, NESA Elevators & Escalators, Shorts Lifts, Vision Elevators, Mitsubishi Electric and Schindler South Africa. In April, South Africa’s largest shopping mall to be built in a single phase, Mall of Africa, opened its doors in Johannesburg after nearly four years of construction, boasting more than 300 shops. The US$220-million property, developed by Atterbury, provides 130,000 m2 of retail space over 550,000 m2. It has 49 sets of lifts and

hoists with 40 escalators, representing a major boost to South Africa’s buildingtransportation market. PwC notes the entry of Mall of Africa will likely bring South Africa’s retail penetration to 80%, representing its peak.[7]

Overall Growth Yields Mix of High-, Low-Rise Buildings While South Africa leads the way in terms of urbanization, the rest of the continent is not far behind. The increasing demand for high-quality retail, office and industrial accommodation described by PwC has been attributed to the expanding middle-class population in Africa and changes in consumer behavior. The African Development Bank estimates the share of the region’s urban population is likely to increase by 50-60% by 2030, up from 36% in 2010.[8] The United Nations estimates Africa’s population will increase from 414 million in 2012 to more than 1.2 billion by 2050. The continent’s middle class accounted for 34.3% of the population in 2010, up from 26.2% in 1980. In Kenya, this segment of

The obsession with modern mall construction, especially in major cities such as Johannesburg, Durban and Pretoria, means brisk business for the numerous players in the South African verticaltransportation market. the population was estimated at 44.9% of the total.[9] Real-estate developers are embracing a mix of high- and low-rise structures to accommodate this surging urban population in a society quickly becoming conscious of the need to conserve both space and energy. Although there are no precise statistics to confirm the high- or low-rise building trend in Africa, some experts say both types of buildings have advantages that could address the twin issues of diminishing urban space and

inadequate energy supply. Fasil Giorghis, chair of Conservation of Urban and Architectural Heritage at the University of Addis Ababa, observes: “High-rise buildings contribute to increasing (population) density, but the advantages of going higher are relative, and, at a certain point, they are no longer there.”[10] Although PwC says more investors are being drawn to Africa’s real-estate sector by the prospect of 20% returns across the region’s markets,[1] Giorghis gives the example of Ethiopia’s capital city, Addis Ababa, of which he says, “Construction costs are a lot more expensive for high rises and are, thus, unaffordable to lowerincome groups.” Giorghis notes there is a future in low-rise buildings, which Stiftung says are more cost-efficient and allow people of different income groups to remain in the same neighborhoods.[10] Consultancy firm KPMG, however, says Africa presents opportunities for realestate developers with an appetite for building tall. The firm points out that constructing high-rise buildings in Africa is, on average, cheaper than it is in other Continued

The major challenge for many African cities (and one with which elevator installers in the region have had to grapple) is Africa’s weak power-generating capacity that the World Bank says shaves off up to 2.1% of the region’s gross domestic product due to frequent power outages. Blackouts leave many elevator systems idle for several hours in cases where the buildings do not have an alternative power supply. Africa’s chronic power problems have escalated in recent years into a crisis affecting 30 countries, taking a heavy toll on economic growth and productivity.[12] The situation has fueled demand for elevator solutions that conserve or use less energy, considering that many property owners have installed expensive diesel-powered generators to ensure elevators remain functional during periods of outages or load shedding. Many suppliers, experts and consumers say MRL elevators fit the bill and that the future looks bright for such systems in the African and Middle Eastern markets if issues related to codes, installation and maintenance are effectively addressed. According to U.S.-based market researcher Freedonia Group, “Space- and energy-saving [MRL] elevators will continue to increase their penetration of the global elevator market through 2017 and will dominate the market in ensuing years.”[7] Freedonia adds that “the equipment market will focus on energy-efficient elevators, escalators and moving walkways.”[7] This focus is evident in the newest high rises being built. In Nairobi, the capital of Kenya, Kings Developers is building the 34-story Kings Prism Tower. Sporting a distinctive, triangularpatterned design, the tower will harvest rainwater to nourish nearby vegetation, have motion sensors that limit unnecessary light usage and boast water-conserving bathroom fixtures.[8] It was designed by A + I Design of New York City (NYC). New equipment being installed is often of the energyefficient variety. At the Otis installation at Mall of Africa, for example, the company’s ReGen technology is being used. By utilizing “energy created by the movements of the lift cabins (down with a heavy load, or up with a light load), and feeding this energy back into the electrical grid,” the regenerative-drive technology could help reduce energy use at the mall by 75% compared with traditional drives, Otis observes. Otis adds: “The Gen2 Switch elevator, suitable for up to seven stories, has the added benefit of being simpler to install, more sustainable and safer during power failures or outages.” Although no precise current statistics can be found on the supply of MRL elevators in the African market, KONE, which launched the world’s first MRL elevator system in 1996 together with its signature EcoDisc® hoisting machine, has recently increased its presence in Africa, particularly in East Africa.

The Finnish elevator firm acquired the elevator and escalator business of Marryat & Scott (Kenya) Ltd. and Marryat East Africa Ltd., its authorized distributor in East and Central Africa, in 2014, saying the move promises to “help KONE. . . improve the availability of KONE’s People Flow solutions in Kenya, Uganda, Rwanda and Tanzania.”[9] Despite the dual challenges of lack of space and energy supply in Africa’s cities, KPMG did a survey two years ago that pointed out an increasing appetite for a share of the region’s market by global construction and engineering firms. “Among the 165 senior leaders in the construction and engineering industry polled, almost 50% are planning to move [into] new geographies [and that the] African continent is the most popular prospect.”[6]

The Gaylord National Resort and Convention Center

by Caleb Givens Just south of Washington, D.C., lies a small development along the Potomac River in Maryland known as National Harbor. On June 25-28, this bustling place was the site of the Building Owners and Managers Association (BOMA) International 2016 Conference, which saw a crowd of more than 3,000 at the Gaylord National Resort and Convention Center for educational sessions and expositions. This show attracts more than just elevator-industry professionals and companies. According to BOMA International’s website (, the organization: “. . . is a primary source of information on building management and operations, development, leasing, building operating costs, energy consumption patterns, local and national building codes, legislation, occupancy statistics, technological developments, and other industry trends.” Elevator companies had solid representation at this year’s expo. As your author made his way around to each of our industry’s booths, he repeatedly heard that attending this show is well worth it, for not only generating new business, but also as a way to meet with current clients in person — a rare opportunity. While Elevator World, Inc. did not have its own booth, we partnered with SnapCab, which had an impressive display. It included a large wall featuring Gorilla® Glass, which is useful as a writing surface and, of course, in elevator cabs (ELEVATOR WORLD, June 2016). Another feature of this technology that caught everyone’s attention was, that by attaching actuators to it,

the glass can become a speaker. The audio, combined with a flush-mounted, flat-screen TV, makes it a solution for media rooms. Also present were the majors: KONE, thyssenkrupp, Otis, Schindler and Fujitec. KONE was showcasing its new virtualreality application that allows clients to stand inside a virtual cab and instantly change its various finishes and components. According to KONE’s Marketing Communications Specialist Paul Jauregui, it is the first elevator company to use virtual reality as a sales tool for cab interiors.

Smart Hydraulics Guarantee Lowest Cost of Ownership Making the case for hydraulic elevators with electronically controlled elevator valves by Tony Aschwanden Bucher Hydraulics AG has developed and manufactured cost- and energy-efficient lift driving packages for decades. Its ability to offer a smooth ride, simple commissioning and fully automatic adaption to different load and temperature conditions is directly related to the electronically controlled lift valve. Cost efficiency is becoming more and more important. Within the elevator industry, there is now a tendency to think beyond the initial investment. The end users recognize that the investment cost is only half the truth. A “cheap” installation could turn into a quite expensive one, considering also the operating and maintenance costs that occur during the entire lifecycle. The typical proprietary systems provided by major elevator companies sometimes entrap building owners. Decisionmakers are now interested to compare not only the initial investment, but also relevant operating and maintenance costs. In addition, they would like to have the freedom to change the service partner whenever they want. This opens a competition that keeps prices for spare parts and services on a healthy level. Within this context, hydraulic elevator drives provide unique advantages, and this is valued in an increasing number of markets. Besides other advantages, this might be one further reason to keep hydraulic elevator drives in demand. Of course, up-to-date cost efficiency may not be reached with old-fashioned hydraulics. To get the full benefit of their physical prerequisites, investments must be made in R&D.

High Technology Is the Key for Low Cost of Ownership Forty years ago, Bucher’s elevator division (at that time under the company name Beringer), in Neuheim, Switzerland, introduced the first electronically controlled elevator valve, LRV. The product is still the benchmark for a highly reliable hydraulic control, providing high riding Continued

comfort at a low cost of ownership. The quality foundation of this electronically controlled lift valve led to several developments within the hydraulic-drive market. Further advantages that contribute to reduced costs of ownership are: ♦♦ Short installation time ♦♦ No wear and tear on moving counterweights ♦♦ Hydraulics are simple and easily accessible – this results in fast and cost-effective repairs

Figure 3: Comparison of an electronic valve and a hydraulic inverter in a downward ride

♦♦ Inexpensive spare parts ♦♦ Drastically reduced maintenance costs compared to traction elevators, since no sheaves and ropes need to get replaced ♦♦ Increased shaft utilization due to no counterweights ♦♦ No expensive headroom designs required The main goal of the LRV’s design is unsurpassed riding comfort independent of load and temperature. In addition, the efficiency of the drive is already remarkably higher than that of Continued

Among vertical transportation devices, escalators and moving walks accommodate the greatest volume of passengers. Today, it is hard to imagine subway stations, airport terminals, malls and other public buildings without them. This much needed book explores escalator safety in detail by studying different types of real-life accidents and providing information on related safety systems and solutions. This book can be helpful to all who need more information on safety codes for escalators and moving walks.

♦♦ No expensive air-conditioning ♦♦ No noise emission or extra energy consumption of cooler fans

Inverter Technology Increases Hydraulics’ Efficiency

Figure 4: Comparison of an electronic valve and a hydraulic inverter’s heat and energy consumption

conventional mechanical valve blocks. Depending on the application, using the electronically controlled valve results in up to 30% less energy consumption compared to mechanical designs. This results, of course, in 30% less heat, which is favorable for all groups involved. As a final benefit, many applications do not require an oil cooler, as they do when running with conventional mechanical valve blocks. Other features include a touchless feedback device showing the current oil flow rate. Due to the touchless “Hall-principle,” it works maintenance free throughout the product’s lifespan. Additionally, a proportional valve controls the bypass oil flow, resulting in the correct flow rate provided to the cylinder. Note in Figure 2 that the motor runtime is shown on the X axis. This means the covered distance for one ride is the same, but, obviously, the runtime may vary drastically when using a mechanical valve. This results in a huge energy-saving advantage for the electronically controlled valve. A further money-saving fact is less downtime due to changing running conditions (e.g., changing ambient temperature or payload). This prevents unscheduled service interventions, which would be necessary on mechanical valves to adapt the mechanical adjustments to new conditions. Figure 2 clearly shows the energy-saving potential of up to 30%, by just being accurate and “on time” at the top floor. This is ensured by the fact the ride curve is maintained, no matter whether the elevator is run with a full or empty cabin, or hot or cold oil. Hence, you just run the installation with the preset parameters, and the installer may set the timing for the deceleration signals at its preferred timing sequences. This ensures there will always be: ♦♦ No deviation due to changing operating conditions ♦♦ The same starting point ♦♦ The same creep speed distance ♦♦ The same acceleration/deceleration slope ♦♦ The same speed ♦♦ A smooth ride without turbulence Furthermore, no oil cooler results in several advantages: ♦♦ No cutout for the hosing/piping to the cooler

166 • September 2016

By using a frequency inverter to control the speed of the hydraulic pump, the efficiency of the hydraulic drive increases remarkably. As a result, the thermal loss gets further reduced, compared to the good values of the electronically controlled valve. The oil flow gets mainly controlled in both directions by the pump speed, which is determined by the individual speed of the attached motor. The right sketch in Figure 3 shows that the heat loss can be dramatically reduced by using inverter techniques. This brings another important advantage: the small amount of remaining heat dissipation can be forwarded by a small cable from the inverter to a brake resistor, which is far less expensive than hosing/piping with required cutouts in the building structure to connect a conventional oil cooler. Additionally, there are fewer noise emissions, and no delays or current peaks when the motor starts.

Conclusion Although energy costs considerations are major, choosing a system with low maintenance costs is even more important. In fact, maintenance costs can typically far outweigh power costs. In case of higher traffic demand, up-to-date hydraulic-drive technologies, such as Bucher’s inverter solutions, meet this request. It provides high energy efficiency without the need to sacrifice the enormous savings in maintenance costs of hydraulics. The following list gives some final arguments why hydraulic lifts are cost effective: ♦♦ Lowest initial investment costs up to five floors ♦♦ Simple commissioning ♦♦ Lower wear and tear than traction applications ♦♦ Twenty percent fewer parts involved for less maintenance ♦♦ Easy and fast access when maintenance is required ♦♦ Electronically controlled hydraulic valves ensure high reliability and guarantee minimum required service. ♦♦ Service partnerships can be procured on the free market. Tony Aschwanden is head of applications at Bucher Hydraulics AG in Switzerland.

Power of a Presence Your author discusses online reputation management for elevator contractors.

by Dean Heasley You’ve been in the industry for years. You’re QEI licensed, which isn’t easy to achieve. Your guys have been with you for a long time, and they get along with your customers. But, if a building owner searched for “elevator repair” in your area online, they’d likely see something that reflects a different history: they would likely find an older website that can’t be used on a mobile phone. They wouldn’t find any ads for your business. And they How do you bridge the definitely wouldn’t find any reviews from other customers. digital gap between This doesn’t reflect the great what your potential business you’ve built. customers see and How do you bridge the digital gap between what your what your business is potential customers see and really like? what your business is really like? The key is establishing credibility online, or, as the marketing industry puts it, “reputation management.” The first and best way to do this is to claim your Google My Business page. This allows you to show up on local searches for the elevator industry. It’s easy to do and takes about 15 min. Just go to and choose “Service Area” type business (because you work at customers’ locations, not your own). Once you create the page, Google will mail you a postcard with your verification code. Then, you verify the page with that code, and you’re ready to be found on Google Maps. This is the key to being found in a local search, which typically occurs on a mobile phone. According to Google, only 33% of small businesses in the U.S. have claimed their page. This alone will set you apart from your

168 • September 2016

competition and make you look more professional. The second way to build your credibility online is to ask your customers to review you. Once you get five reviews on your Google My Business page, Google will show the star rating in orange under your website in searches. This can say to potential customers that you’re reputable and digitally up to date. According to marketing-platform company Vendasta: ♦♦ 92% of customers read online reviews before making a decision. ♦♦ 80% of customers trust an online review as much as a personal recommendation. So, getting reviews online is like getting personal recommendations to everyone who reads your reviews. The third way to boost your online credibility is to regularly post in social media. Some property managers have time on their hands, and they use it to surf Facebook, Twitter and, if they want to look ambitious, LinkedIn. Get your administrative assistant to post a few sentences about your successes a few times a week. This will also help your search engine rankings. Even posting once a week on each platform will help with credibility. And, if potential customers follow you on social media, you get top-of-mind awareness with them. I have a window-covering client that uses Facebook and Instagram to feature before-andafter photos of draperies and blinds. They use these posts not only to gain new business, but show customers when they’re doing a presentation. In the elevator industry, beforeand-after photos of machine rooms are a great way to show your attention to detail to potential customers.


Mobilize Your Safety Program Each Mobile Safety Meeting now has Yes/No questions implemented to help grade weekly understanding.  By using a mobile phone or tablet, Safety Meetings can now be reviewed by mechanics in the field, or at home, and digitally signed and automatically graded verifying that each one has been completed.  The form, and signature, is then transmitted back to the office supervisor, or designated person, for record keeping.  Using a web-based management tool, a supervisor can schedule weekly safety meetings for each mechanic by the desired date they would like each one completed. If any of the meetings are not completed as scheduled the system will flag the supervisor for immediate follow up with the selected mechanic(s). Create more time on the job and less paperwork while maintaining a safe work environment.  Also available: Mechanic, Vehicle and Jobsite Safety Audits, and the ability to track and schedule any required OSHA, Mechanical and Internal certification requirements.

Another way to boost your Another way to credibility online is to post relevant boost your information on your website. This can be as easy or as hard as you make credibility it. The easy way to create content is online is to post to get someone to interview you and record it. Then, get it transcribed relevant and turned into blog posts or information on webpages. This takes very little time. your website. I built an entire website for an elevator consultant from a half-hour This can be as interview; there is enough good easy or as hard information from the interview for about 10 updates. This used to be as you make it. called “blogging,” but now it’s just a regular part of updating your website. (It doesn’t have to be in the “blog” section.) You could also link to an interesting article from your favorite industry magazine. Adding regularly to the “News” section of your website is easy, as well. According to Digital Marketer Pro, you should be adding relevant content to your website two or three times a week. This seems like a lot, but your administrators can do it on a Monday, Wednesday and Friday schedule. A final way to make your online reputation higher is to make sure your name, address and phone number (NAP) are consistent across all the local directories. According to Yext, a leader in local reputation management, “today, four in five consumers search for local businesses online. When consumers find incorrect information about a business online, 73% lose trust in that business.” Your Google My Business page, Facebook page, LinkedIn profile, Yelp page and Twitter NAP should all match exactly. The company name should be exactly the same. The address and phone number have to have the same capitalization, punctuation and spacing. Google looks for consistency. When it sees inconsistency, it ranks pages lower. Consistency is rewarded with higher rankings, because it appears more authoritative. These are all simple, straightforward ways to improve the way you look online to potential customers. You and your team can improve your online reputation very easily.
