SafeLine MX2

SMALL, INTELLIGENT AND POWERFUL

Short installation time with little disruption to the building during installation.

SafeLine MX2 is probably the world’s smallest EN81-28 and EN81-70 compatible emergency telephone. Despite its size it is both intelligent and powerful; perfectly suitable for most types of installations. SafeLine MX2 uses a 10-30v supply separate from the telephone line. This makes the quality of the MX2 unaffected by reductions in line quality. Test alarms can be sent to a separate telephone number on a configurable interval. SafeLine MX2 can be configured in five different ways: Using the built-in keyboard, remote with a cell/mobile telephone, connected to a computer using SafeLine Pro software, from remote with a standard analogue telephone or from remote using a ProLink unit connected to a computer running SafeLine Pro software.

SafeLine GL Change from telephone line to GSM in minutes

The unit replaces a standard PSTN landline and can be installed in the machine room, lift shaft or on the car roof. It can also be placed in a central position in the building in order to be connected with multiple telephones, either parallel or in a daisy-chain (serial wiring).

Guest Editor’s Overview Focus on Safety, Quality Key To Sustainable Growth by Marcello Personeni Let’s go back a few years, to 2009. In that year, Italian company Sematic started its direct operations in India. As a company, we were ready to open our automatic doors to Indian customers and discover a country that we had been curious about for years. What we found was astonishing: history, culture, natural beauty, quality of life, hospitable people and an industry with all the components necessary to make our investment worthwhile – a dynamic economy, strong urbanization rate and growing demand for elevator equipment and services. The years following our Indian launch have been spent planning and developing our local manufacturing and commercial presence, creating structures that allow us to compete in an ever-morecompetitive market, meeting professionals during fairs, events, debates and conferences, and listening to our customers about their needs. We deepened our knowledge of the nation, the market and its dynamics. At the same time, we came to understand the great challenges India will face in coming decades and realized that in order to sustain rapid demographic growth, the population’s quality of life (in large urban centers, as well as in rural areas) must be improved by making infrastructure, connections, resources and services available. Everyone, in every sector, may provide possible answers to fundamental questions that are still unresolved. The questions we must ask ourselves are, “What can the lift industry do?” and “What can Sematic do?” Our answer is that we can focus on quality and safety in an effort to provide ever-more-reliable vertical transportation services, in turn, improving the daily mobility of people in buildings. With the spread of urbanization across India, the use of elevators in everyday life has become increasingly common. Even though elevators are one of the safest forms of transportation, we still experience too many accidents due to lack of safety devices or improper installation and maintenance. Elevator-component producers must be active in this sense, and adequately reinforce the value and importance of safety devices. Safety awareness is key to accident prevention. For an elevatordoor manufacturer such as Sematic, this means communicating the importance of fire-rated doors. Failing to do so can result in serious consequences in terms of structural damage, not only for an elevator system, but also for an entire building. Worse, it can put Continued people in danger.

We will never forget the experience of visiting the Punarvasu Building in the Tarangan Complex, Thane, where an October 2009 fire took the lives of six firemen who were trapped in the high rise’s fire elevator. It is necessary to remember such tragedies in order to avoid them in the future. We think we are on the right track, but we must insist on it. Thanks to higher safety and quality standards, continuing professional development and debate about safety issues, the Indian elevator market is steadily improving. If we focus on safety and quality in all the aspects of our work, from manufacturing to employee training, we will be ready to face any challenge the vertical-transportation industry brings our way, in India or anywhere else in the world. At Sematic, a commitment to design and manufacture increasingly reliable, safe and efficient solutions through excellent production processes and products has always been our top priority. Making this a priority in India means we are contributing to improving services here and, in however small a way, repaying the debt we owe to a country and industry that has welcomed us with open doors. Marcello Personeni is Sematic Group Marketing manager, in charge of the company’s strategic and operational marketing activities, as well as its business development in India. He holds a bachelor’s degree in Management & Engineering and a master’s degree in Business Strategy.

Comments I must object to the views expressed by Amit Maitra in his Guest Editor’s Overview, “Looking Forward to Brighter Days,” in ELEVATOR WORLD India, 4th Quarter 2013 issue. He writes that the number of inspectors for licensing elevators, which is controlled by the statutory authorities, falls far short of what is needed. However, readers should be well acquainted with our efforts to bring down accident rates in the state of Maharashtra. We have, occasionally, made firm decisions regarding user safety.

For example, we have made installation of automatic rescue/overload devices mandatory, implemented specifications regarding car-apron length and encouraged awareness programs by lift manufacturers and contractors. We are adopting best practices, and the licensing process is conducted under existing acts and rules. Following the high court’s orders, we strove to recruit engineers to perform periodical inspections, and we succeeded. The total numbers of lift inspectors in our offices are two electrical inspectors, 12 assistant electrical inspectors and 120 Junior Engineers and Application II Engineers. Statements such as Maitra’s may create fear and discomfort among elevator users.

Escalators, Elevators Help Ease Rail Commutes

New Units at Ranchi Ranchi Station is scheduled to receive two escalators to help its 70,000 daily passengers cross smoothly from one platform to another. This would make Ranchi the first railway station in the state of Jharkhand to get escalators. Platforms 1 and 4/5 are targeted for the units. The equipment, which is to come from China, is to be installed by May.

Escalators Part of Improved Coimbatore Junction By late November 2013, escalators had been installed and infrastructure testing was underway at Coimbatore junction, heralding an anticipated December 2013 opening of a new, second subway, The Times of India reported. The escalators were to link all platforms to the new subway. A commuter remarked the facility will be extremely useful, particularly for senior citizens. Coimbatore is one of several major stations in India having recently received or undergoing upgrades.

Kozhikode Station Welcomes Upgrade In October 2013, the Kozhikode railway station welcomed four new escalators and nine elevators, bringing the station closer to being a world-class facility, The Hindu reported. The upgrades make Kozhikode’s railway station the first in South India to have either elevator or escalator access to every platform.

Mumbai Monorail Riders to Wait for Escalators While, as of January, Mumbai’s monorail was expected to open in approximately a month, riders will likely have to wait a while longer for escalators, The Times of India reported. A Mumbai Metropolitan Region Development Authority spokesman said the escalators have been procured and will be installed by March. They were not part of the original contract. Each of seven stations in the line’s first phase, between Chembur and Wadala, will have four escalators – two from ground level to concourse and two from concourse to platform.

Commuters Doubtful of Proper Upkeep The approximately 80,000 passengers who use stations within the Mass Rapid Transit System (MRTS) each day between Chintadripet and Perungudi doubt that lifts and escalators in 13 stations will be properly maintained, The Hindu reported in December 2013. Although MRTS made repairs, commuters said they worry that damaged facilities will not be repaired in the future, noting that many lifts and escalators were out of service in 2013. Railway officials said issues with contractors over pay led to lapses in maintenance work.

Delayed project delivery, mainly owing to improper management, lack of capital and land-acquisition disputes, is seen as a major hurdle across the country. Nationwide, up to 25% of housing projects are said to be impacted, leading to an increase in inventory.

The Indian residential real-estate market is marked by a: • Decline in the launch of new projects • Housing shortage, estimated at 18.78 million units across India • Lagging luxury segment • Healthy Bangalore

Overall demand for luxury properties registered decline across India, and project launches in the luxury segment have also witnessed significant decline compared with the previous year. Bangalore, followed by Chennai and Pune, has been rated as the leading business destination in a recent research report including such factors as connectivity, talent pool, living standards and availability of office space. Information Technology/Information Technology enabled Services (IT/ITeS) followed by the banking, financial services and insurance (BFSI) sector, leads in space absorption across key cities. However, according to a recent report by Knight Frank, the segments are expected to witness a role reversal during 2014. With recent efforts to ease bank-licensing policies, the BFSI sector is forecast to drive demand for commercial properties ahead of the IT/ITeS sector during 2014. Demand for commercial space from the manufacturing and services sector is expected to grow moderately, at 12-15%. Micromarkets in central Mumbai, including Parel, Lower Parel, Dadar and Prabhadevi, are expected to lead annual returns to investors at close to 20%. Returns in other areas in the Mumbai Metropolitan Area hover around 12-15% per year which is higher than those for other metropolitan cities. While return on investment in the NCR is around 8-12% per year, the Bangalore and Chennai markets yield around 12-13% annually. Among Tier II cities, Indore, Bhubaneswar, Kochi and Coimbatore lead in the demand for office space. The commercial real-estate market in Hyderabad has taken a hit during recent months.

India-entry strategies. With further efforts to relax requirements, retail real estate is expected to expand considerably during 2014. The total mall supply across India expanded considerably during 2013 and is estimated around 12.7 million sq. ft. The NCR, followed by Chennai, witnessed the launch of projects that added

According to a recent report by Tophotelprojects.com, approximately 300 new branded hotels are expected to come on line in India by 2016. up to 5.3 million sq. ft. and 2.23 million sq. ft., respectively. Mall supply in other metropolitan areas, such as Mumbai, Bangalore and Kolkata, stood at around 1 million sq. ft. each during 2013. Several multinational and domestic retailers intend to enter new markets in Tier II cities and are trying to consolidate their positions in their current cities of operation before expanding further. Tier II cities expected to witness considerable growth in the retail segment include Jaipur, Kochi, Ludhiana, Indore, Nagpur and Udaipur. On the hospitality real-estate front, notwithstanding the current lull in economic activity, new hotel construction is expected to pick up steam during 2014. Multinational hospitality majors such as Accor, Carlson Rezidor, Hyatt, Hilton and InterContinental Hotels Group PLC have all planned to expand their presence. According to a recent report by Tophotelprojects.com, approximately 300 new branded hotels are expected to come on line in India by 2016. Reported by e-Research & Publications India Pvt. Ltd.

Tokyo Earthquake Preparation for Elevators According to The Japan Times, local governments in the Tokyo area are taking precautions for elevators in the case of an earthquake in the city. Stockpiling drinking water in elevators and equipping them with portable toilets are among the measures being taken to aid the estimated 17,000 people who could be entrapped in the city’s units if a magnitude-7 earthquake struck the area. At least 84 of the city’s 150,000 elevators entrapped passengers as a result of the March 2011 Tohoku Pacific Earthquake (ELEVATOR WORLD, May 2011). Some were not rescued until at least 9 hr. had elapsed. At least one ward has begun equipping elevators with water, blankets and “emergency boxes,” and another plans to equip 160 units with the boxes by April 1. Finally, a government panel anticipates many people could be stranded near the tops of high rises without water and electricity if elevators cease functioning in a natural disaster. It recommends the stockpiling of food and drinking water for these, whom it has dubbed “upper-floor refugees.”

Engineering

Vertical-Transportation Design Planning What manufacturers and architects should be aware of in the planning stages of a building’s elevatoring by Samson Rajan Babu Elevator contractors are quite familiar with their specialty tasks – they do sales engineering, negotiate and sell elevators, produce shop drawings, procure materials, install elevators and carry out maintenance. However, the background information (i.e., how a verticaltransportation solution is selected for a new building project) and the factors that govern elevator selection (i.e., how the original elevator layout and specifications came into existence) remain somewhat hidden. This article provides an insight into understanding the essential design efforts that go behind the verticaltransportation planning of any new construction project. It also intends to help architects formulate a scientific method of developing, integrating and verifying a vertical-transportation system design within their projects. It is hoped the information presented in this article will also help elevator contractors understand tender specifications and drawings in a better way and be informed and decisive, while complying with or deviating from a project requirement. It is also intended to help elevator contractors properly estimate their costs and liabilities on a new project and present attractive value engineering options to their clients, while increasing their chances of winning a project.

Applicable Codes There are applicable building-design codes for projects based on their geographical location. These include (but are not limited to) international-building, life-safety, fire-protection, seismic, accessibility and local-municipality/ civil-defense codes. While these are mandatory requirements, the consultant and/or owner

26

ELEVATOR WORLD India • 1st Quarter 2014 •

might choose to exceed the minimum requirements and provide additional/superior features, such as evacuation communication systems, evacuation elevators, etc.

Performance Targets Any new project has owner requirements, and most established brand owners have their own vertical-transportation design and performance requirements. Design requirements include average interval, average waiting time, average time to destination, car capacities, and car and door sizes. While starting a new design project, consultants should check with the owners for their published design guidelines. If this is not available, the consultant should propose standards based on the international best design practices and the project’s brand positioning at the geographical location. This becomes the “design criteria” for the project. Continued

Analyzing Population and Vertical Circulation

Elevator Sizes/Capacities

For each type of building project, the population and vertical circulation of people and material inside the building must be elaborately studied. This includes types of users, populations on each upper floor, parking spaces on parking floors, loading docks, arrival/exit patterns, access-control concepts, bulk arrival (including transportation for both the public and staff ) scenarios, interfloor circulation patterns and peak traffic estimation. Main lobby floors should be identified for arrival. Exit scenarios and the volume of peak traffic should be estimated using practical and working knowledge on each building type. Similarly, high-traffic floors that are not main lobby floors should be identified, and peak traffic to/from these floors is to be estimated.

Depending on user space requirements, comfort levels and various code requirements, the most suitable car sizes/capacities and door sizes should be identified for each elevator group. Even though an elevator analysis might minimally require smaller elevators, an architect might select larger elevators to serve the above requirements. The option to provide a machine room at the top of the building should also be discussed with an architect in reference to machine-room-less (MRL) elevators, which may have different capacities, speed and range.

Elevator Traffic Analysis

Various traffic patterns and peak traffic identified throughout the day at the building can now be analyzed via calculations or a Traffic Segregation simulation. A typical elevator traffic analysis involves assuming To realize the elevator systems’ maximum efficiency, it is ideal various elevator operating parameters (door times, passenger to have dedicated elevator groups for each user type. It also helps movement times, acceleration, etc.), and such assumptions must in improving user comfort, access control of protected areas and match desired car and door sizes. All such assumptions made at exclusivity for VIP users. However, it may not be economical or this stage must be practically achievable by any elevator viable commercially.

circumstances as building plumb deviations, seismic designs, fire-rated entrances, wind-shear noise, piston effects, special safety features, etc.) should also be considered, and the core sizes increased as necessary. Type of construction for the elevator core walls is then finalized, considering the structural and fire-code requirements. For quick reference, all the elevator groups should be consolidated onto a spreadsheet showing all relevant dimensions and specification data. This spreadsheet could be used as a cross-reference, while verifying the elevator tender response for the project. Elevator contractors are required to confirm their compliance or noncompliance to each item on this summary sheet.

Core Layout Based on the final core dimensions, the elevator cores should be laid out on the plan drawings. Structural support requirements for the guide rails, separator beams, trimmer beams, entrance frames, machines and controllers should be identified, and suitable provisions should be made for the size and type of construction. Door structural openings should be approximately shown on the plans. It is important to note that the location of door structural openings and front-wall dimensions are approximate. This must be finalized and constructed based only on the elevator supplier’s shop drawings.

An elevator core drawing

Machine-Room Layout For each elevator core, the machine-room layout should be finalized, taking the requirements for easy access and safe working conditions into consideration. Machine-room heights include joist beams/lifting hooks for maintenance. For heavy machinery, where possible, a trap door should be included on the machine-room

floor in order to drop the machine to a floor with elevator service, then move it to the ground floor for future maintenance/ replacement. For MRL elevators, the location of an emergency rescue panel outside the hoistway should be identified.

Structural Coordination The structural loads on the guide-rail support system, impact loads on the pit buffer, reaction loads at the machine room and lifting-hook capacities should be reviewed, and the structural frame (reinforced cement concrete (RCC) beam/column/slab/ wall) should be designed to meet the requirements. The structural fixing (anchoring) requirements for the guide-rail brackets, machines and other steel elements should be reviewed, and a suitable substructure (RCC or similar) should be provided. The size of structural door openings, trap doors and rope holes are to be compiled, and their impact on the structural stability of the core wall system should be reviewed by the structural design engineers.

Mechanical Coordination The mechanical requirements for efficient functioning of the elevator equipment should be reviewed, and suitable provisions should be made by the mechanical designers to remove the heat generated by the elevator equipment and provide suitable ambient conditions within the machine room. These provisions can include heating, ventilation, air-conditioning, ducting, routing and diffusers. Special requirements, such as air-conditioning for the elevator car, pressurization, stack effect, smoke mitigation and noise reduction requirements should also be reviewed, and a matching mechanical design and additional equipment provided to prevent any detrimental effect on the elevator systems’ performance. Acoustics and vibration characteristics of the elevator equipment should be reviewed, and suitable coordination and adjustments may need to be carried out to reduce such undesirable effects generated by the elevator system.

Electrical Coordination The electrical requirements for efficient functioning of elevator equipment should also be reviewed, and suitable provisions (suitably rated isolators, fuses, fire protection, and cable sizes, shields, routing and containment) should be made by the electrical designers to supply the power required by the elevator equipment. Standby-power requirements should be identified for specific elevators and suitable provisions made in this stage through automatic transfer switches to provide generator power to specific elevators, as well as other building services. The requirement of a battery-operated automatic rescue device and regenerative drives for specific elevators should then be reviewed and finalized. Equipment sensitive to electromagnetic interference (EMI) at the site should be identified, and the elevator power-supply circuits should be suitably designed to prevent EMI with such equipment.

Lighting Coordination Normal lighting requirements for the machine room and emergency-lighting requirements should be reviewed. Suitable lighting fixtures can then be provided to achieve desired brightness inside these spaces. Special elevator-car interior lighting and lighting effects should be reviewed and incorporated.

Architectural and Interior Design Coordination Related elevator spaces (shaft, lobbies and machine rooms) should be reviewed in parallel with the interior design concepts and appropriate alignments carried out. Suitable lobby widths are necessary to achieve international standards in user comfort. Elevator-door handing (which side they open) is to be reviewed in relation to the surroundings and elevator approach, after which the most suitable should be selected. Depending on the front-wall cladding thickness and floor-finish thickness, suitable adjustments can be made to the architectural positioning of each door opening. Special attention should be paid to aligning the elevator-door openings opposite to each other. Placement of hall-call stations, lanterns, indicators, firefighters’ switches, emergency control panels (for MRL elevators only) and related equipment regularly installed at the landings should be reviewed, adjusted and aligned to achieve the best-looking lobby possible.

Accessibility Design Coordination Every passenger elevator should be reviewed for compliance with accessibility codes and features. Elevator car sizes that allow full rotation of wheelchairs, auxiliary car control panels for the handicapped, maximum height of push buttons from floor level, and Braille and tactile features on push buttons are examples. Special accessibility features such as induction loops for the hearing impaired, voice announcements in the local language and tactile pavements in the elevator lobby may be reviewed on a case-to-case basis and adopted as deemed necessary. Riser Diagram Colored.xlsx

Tender Documents Traditionally, manufacturers estimate their tender price based on the elevator specifications (and elevator drawings, if any). However, it must be noted that elevator specifications always cross-reference various other specifications within the master specifications. It is recommended that elevator manufacturers read all relevant codes and specifications to understand how the elevator system is required to coordinate and work with other project equipment and design concepts.

Lift

Doors The importance of choosing liftdoor characteristics per application

by Marcello Personeni Which is the best automatic lift door for a freight lift? Which one best suits the needs of a super-fast lift in a high-rise building? Which is able to withstand vandalism and high passenger traffic? Which is the ideal product for a modernization project in a historical building? Each installation requires lift doors with distinctive, well-defined features and technical characteristics, to satisfy specific expectations and needs. Those involved in choosing the right doors include those who designed the lift system, those who designed the whole building and, above all, building users. The functional and aesthetic characteristics of automatic lift doors are always combined with essential product requirements described by the international standard for the lift sector. In many cases, this fact significantly contributes to the definition of the distinctive characteristics of a door component. In this article, some of the solutions that Sematic can offer to customers, architects, designers and installers will be

38

ELEVATOR WORLD India • 1st Quarter 2014 •

presented. Each Sematic product is specially designed and manufactured to offer customers the best possible solution for each specific application and requirement. The company’s products range from standard to tailor-made automatic doors for any type of elevator, both for people and goods transportation. They have been installed in skyscrapers; residential, civil, commercial and industrial buildings; hotels; hospitals; and cruise ships.

High-Speed Lifts High-speed applications are the most advanced in the lift industry. Typically installed in residential and commercial high-rise buildings with high traffic flows, super-fast complete lift systems and all

their components must guarantee top performances, together with maximum safety and comfort. Usually, automatic lift doors for high-speed lifts feature high adjustability, and reinforced and highperforming components, panels and headers, which are designed to move heavy panels in short times and with low noise emissions. Door-specific variables to be considered during product design and manufacturing are: ♦♦ Performances required (in terms of opening/closing cycles), which significantly affect travel time ♦♦ Perceived quality (noise and vibration levels, and profile smoothness) ♦♦ Reliability (call-back rates and performance preservation and quality over time)


♦♦ Energy savings and aesthetics (design and flexibility to suit different claddings and executions, together with the ability to master glass, for example) To satisfy all these requirements, door manufacturers have developed a complete range of solutions, such as the Sematic 2000 B-HR, comprising such door drive controller special features as adjustable opening and closing speed profiles, real-time moving-mass calculation algorithms, speed-profile automatic downgrade, standby mode and battery backup. Specific mechanical devices are also used to seal the cabin and landing doors during the lift travel to increase comfort.

Freight Lifts Freight lifts are used to transport goods in airports, underground passages, railway stations, shopping centers, hospitals (e.g., for stretchers), industrial premises and parking lots. Resistance and durability of all the components are crucial in these contexts. In particular, automatic doors for freight lifts must withstand heavy loads and potential hits (i.e., from forklifts), so they

need to be not only robust, but also able to guarantee a high level of service and reliability in all operative conditions, even in the extreme ones. Sematic 2000 B-G automatic lift doors, the openings of which can reach 6,000 X 5,000 mm, satisfy these requirements, thanks to a set of such constructive solutions as reinforced clutches, frames, panels, bigger rollers, and upper and bottom tracks made of high resistance materials, specially designed for this application. Installation techniques such as the partial installation of door posts on the floor also contribute in enhancing the stability of the entire door systems.

Modernizations Lift modernization projects aim to improve safety, accessibility, reliability, efficiency, performance and comfort in existing systems, while simultaneously lowering maintenance activities and energy consumption. Door manufacturers are able to offer a wide range of solutions for the complete replacement of old lift doors (both manual and automatic), as well as of some of their key components. Sematic offers its 2000 C-MOD in this

market segment. It is suitable for an extensive range of existing installations and customized according to specific markets and their characteristics, such as shaft dimensions or local regulations. Space saving of components is one of the most important aspects of maximizing cabin capacity and accessibility. Bottomtrack packages with a minimal amount of space (approximately 115 mm), frameless doors and recess installation are a few examples of solutions that can be adopted to reach those goals.

Panoramic Lifts Lifts aren’t always just about moving people; sometimes, they can be a distinctive, iconic feature of the building itself. Aside from their functional ability, panoramic lifts can be a focal point of any building, providing a combination of elegant finishes and all-around visibility. These can make the most of, for example, an open hotel foyer or a shopping-center atrium. Each panoramic lift can be tailored to suit a particular architectural requirement or design concept, and its components must be customized in order Continued

reinforced panels with adequate thickness and made of anti-scratch materials. In addition to these safety measures, attention has to be paid to prevent forced openings of car doors. Special car-door locking devices are implemented to help present this action, which can cause serious hazards.

Inclined Lifts

to guarantee the best possible aesthetic and functional performances. For automatic lift doors, these requirements are satisfied through material selection (full or framed glass panels), panel shape (round doors) and special executions, such as doors with hidden bottom tracks or doors with under-driven operators, which include exclusive design advantages, such as reducing the visible size of the car-door operator from the floor hiding the lift-door mechanisms under the floor level. All these characteristics can be found in the Sematic 2000 R.

stations, schools, universities and public parking, are often subject to vandalism. Even if it is quite impossible to develop a 100% vandal-proof system, the lift industry’s efforts to improve lifts’ resistance to vandals’ destruction have already achieved significant results. Component manufacturers have developed a wide range of solutions that contribute to the improvement of lifts’ overall safety. For doors, these instances are translated into a series of precautions, which make the system more robust and resistant to damage and breakage. For the landing doors, these precautions include, for example, a mechanism cover plate, protected emergency unlocking device, corrosive-fluid-resistant bottom track and

Inclined lifts allow the overcoming of slopes and guarantee transport between different levels on an oblique path. The lifts used for this purpose include high-tech solutions and must guarantee a high degree of adaptability to different jobsite conditions. This precludes mechanical coupling of car and landing doors, one of the fundamental working aspects of this specific component. To overcome this problem, some door manufacturers have developed doors with optical coupling. Here is an example of how the Sematic SWS® for this special application works: car and landing doors are both equipped with linear belt traction operators (each one with its own engine) and couple through an optical device, which should allow only a minimum misalignment between the centers of the emitter and the detector. Optically coupled doors for inclined lifts must guarantee perfect functioning of the systems on levels with inclinations. Usually, 15-75° are allowed. For complex installations, it is even possible to have different inclinations from floor to floor. Additionally, since these lifts are often installed outdoors, protecting the components is fundamental (i.e., for a fully covered operator with a high IP rating and materials that guarantee satisfactory performances, even in extreme weather conditions).

Safety Requires Quality How to choose the correct brake by Hermann Bestle The global effects of competition in the elevator industry have repeatedly caused price to play a major role, even for components closely tied to safety. The price/performance ratio for these products is very similar internationally. Therefore, performance and reliability are frequently economized on low-price products. Taking safety brakes as an example, this article is intended to show how a well-founded selection of reliable products can be made in spite of the intense competitive market and explains what to take into account to avoid unpleasant surprises. Its suggestions and recommendations are, of course, also applicable for other safety-relevant components. The globalization of the elevator-drive market, the enormous competitive intensity and the resulting problems of reproduction or production in countries with low production costs have caused an enormous amount of competitive pressure, even with safety-critical elements. Years ago, a clear commitment to reliability and the best quality could be observed. Nowadays, when talking to market participants, it becomes more and more obvious that price has the top priority. Most major global elevator manufacturers have the ability to compile detailed requirement specifications based on very detailed product knowledge and intensive market experience. The required components -- for example, safety brakes -- can be adapted to the application very quickly and evaluated through tests. However, this is not applicable for the supplier industry in its entirety. For example, motor manufacturers that do not obtain the corresponding feedback via field data and do not have the necessary resources to employ a large engineering team

Gearless drive with a Mayr ROBA-stop®-silenzio® safety brake

normally work with simpler means to specify and test a brake. Most elevator components are launched by medium-sized companies with a lot of experience. The accident and malfunction statistics with regard to passenger lifts confirm that technically high-quality products are used here, which have been tested beforehand in an appropriate and reliable manner. Passenger elevators are among the safest means of transportation. Nevertheless, each accident and breakdown should be considered an incentive for further improvement. Up to now, only a few experienced elevator-brake manufacturers have been active on the market. Quality and reliability were guaranteed due to the respective competence. However, the rapid development harbors an enormous danger potential. The situation has fundamentally changed because of young market participants who do not have a lot of experience. Which criteria can a manufacturer of elevator motors – especially in the field of gearless technology – apply in order to choose a reliable brake? First, the possible supplier should be considered thoroughly, just as in general purchasing. A company does not only qualify itself by being able to manufacture brakes; well-founded experience of brakes for elevator drives must be available. Furthermore, the company has to have had a large selection of brakes on the market over a number of years. Only then is it capable of knowing the risks and able to provide reliable products. Responsible handling of safety-relevant components also means a “state of the art“ quality system, an Continued


The cooperation with globally operating elevator manufacturers has shown that those large-scale enterprises go to considerable lengths to accurately specify the requirements for safety-relevant components and adjust them in elaborate testing procedures. Furthermore, due to practical day-in/day-out field experiences, these enterprises have a corresponding Each Mayr elevator brake has a “Type” tag with an article number and unambiguous serial number market input that makes it easier to intended to guarantee complete traceability and continuous quality assurance for each delivered brake. consistently add detail to and work on the products or product requirements, and unambiguous traceability of the parts and further requirements for absorb critical points into the qualification process. a modern quality business.

Smaller elevator manufacturers also do solutions meet the requirements of all existing and modern drive not have the same scope and often only have regional application concepts. During our work with non-European customers, we areas in which certain problems may not occur very often. This realized that these quality criteria are not often demanded and that means that if such a drive manufacturer needs reliable brakes, it application-relevant certifications essential in Europe are not will orientate itself on points with which it is familiar. However, in always required. The purchasing agents often rely on the supplier, the course of business development into other markets, it might ascribing to the motto, “He knows what he is doing.” For well be confronted with different conditions that bring new customers who install safety-relevant components (especially in problems. markets in which the quality philosophy is less established and On compact direct drives, which can be subject to high external quality systems even less so), it is necessary to find a reliable temperatures (for example, in elevators in hot regions under glass partner. The customer’s goals should be to pursue ceaseless roofs), the maximum operational brake temperatures can reach development with regard to quality improvements and produce more than 70°C. The increase in temperature causes the material to their own regulations and procedures in order to guarantee the expand, which can have fatal consequences. If, for example, a continuous quality and reliability of the products. microswitch stops functioning correctly due to the heat convection, a service operation might become necessary. The costs for such an operation (especially if the machine is installed in foreign markets) can quickly amount to several thousand euros. The assumed cost reduction achieved by selecting a cheaper product is quickly lost, as the additional expenditure for service operations rapidly far exceeds the costs saved. But, this is only the lesser evil. If such occurrences also lead to liability cases, the consequences are considerably more serious. In addition to the costs, there are safety problems, which, if severe enough, can threaten the existence of the manufacturer of the complete systems. Not long ago, an accident in Japan and its related news coverage caused considerable image damage for the affected company. This made it clear to the entire branch how a single event can drastically affect a company overnight. This shows how important it is to rule out safety risks at all costs by applying highly reliable components. When selecting a brake supplier, the evaluation of the company in regard to quality and reliability is important, but the product specifications and their adjustment to the required criteria are of the utmost importance. Here, it is especially important to ensure not only that the specified values are achieved in new condition, but also that the running behavior over the system’s entire service lifetime is taken into consideration. Internal tests at our site of manufacture, together with renowned elevator manufacturers, have shown that the noise behavior of brakes in operation, for Continued example, can fundamentally deteriorate.

It is extremely important that the performance values achieved in new condition are maintained over longer operating periods. If an elevator machine is located close to living space, distracting noises can cause complaints and follow-up costs. The people concerned will hardly accept the elevator becoming considerably louder after a relatively short operating period, when the agreeable noise behavior of the new condition is lost. For example, safety brakes with simple elastomeric damping can easily be mounted so they achieve acceptable noise values in new condition; however, these values are not constant over an adequate service lifetime. On standard market brakes, a substantial increase in noise value can occur after only 100,000 switching actions. This service lifetime is utterly unacceptable in the field of elevator technology.

Two brake circuits working independently hold the load on the ROBA-stop®-Z dual circuit brake. Even in case of a total breakdown of one of the brake circuits, the other circuit fulfills its safety function without restrictions.

And Introducing ... ART Gate®, the in‑home elevator gate designed to slide around the side of the cab.

Among other things, it is not common knowledge that temperature influences the damping and noise behavior. If the brake is energized over a long period of time, an operating temperature of approximately 60°C is produced. This causes the rubber elements used for noise damping to expand, which improves the noise behavior. Therefore, a brake at operating temperature does not cause problems during noise measurement. This also makes it easier to present the noise behavior of brakes at product presentations as being considerably better than it probably will be in reality. Often, it seems that cost of the elevator components is the most important factor. While reducing cost in elevators is an extremely strong driver, it should not be top priority. Instead, that should be safety and reliability. Brakes play the central role of passenger safety in elevators. In selecting the right brake, not only technical specifications should be considered. Reliability, experience, quality procedures and references should also be looked at before a supplier is selected. Hermann Bestle is advertising manager for Chr. Mayr GmbH + Co. KG.

Performance Analysis Planning groups of elevators for optimal performance and efficiency

by Pieter J. de Groot

Group Configurations Define Group Efficiency and Performance All groups with large cars are inefficient. During periods of heavy traffic, large cars make many time-consuming stops to distribute and/or collect high numbers of passengers. This implies long round-trip times (RTTs). Their performance and efficiency is worst during periods with heaviest traffic. During average traffic conditions, RTTs are short, and few passengers enjoy abundant car space. This article’s aim is to prove that the configuration of groups (and, particularly, the relationship between the number of cars and the number of floors served) defines the performance potential of groups. Until now, the theoretical performance potential of groups was not known. This has been a major handicap for the planning of groups that deliver optimal performance and efficiency under all traffic conditions. The discovery of the inherent relativity of group characteristics has solved this problem, because it makes the performance potential of groups transparent. Subsequently, it has enabled the design of intelligent destination group controls. These developments enable elevator contractors, consultants and architects to control all aspects of groups, including service qualities, and space and energy requirements.

The Inherent Relativity of Group Characteristics To appreciate the logic of relativity, consider a building served by one large elevator, and compare its performance with a group of two elevators. The cars of the two-car group can be much smaller – particularly so if we also consider

48

they will make fewer stops (i.e., reducing their RTTs). Consequently, their contract loads can be less than 50% of the large single car they replace. Passengers in the smaller cars will benefit from shorter waiting and travel times. Each increase of the number of cars of a group allows the use of smaller cars and improves time-dependent service qualities. This logic is true for any group and any type of group control. It is an inherent characteristic of groups. A six-car, 800-kg-capacity traditional group (with up/down buttons in the lobbies and floor buttons in the cars) will outperform and deliver far better time-dependent service qualities than a four-car, 1600-kg-capacity traditional group. Their space requirements are identical, and the energy consumption of the six-car group is approximately 25% less. Increasing the contract load of a traditional six-car group with small cars does not affect its time-dependent service qualities. Larger cars will only enhance passenger comfort. If we increase the contract load to increase transportation capacities for the purpose of serving additional floors, RTTs and all timedependent service qualities will be worse. Existing traditional groups with six large cars usually serve three or four more floors than the number a four-car group does. These six-car groups deliver worse performance than four-car groups, although their capital and maintenance costs are much higher.

Traffic Simulation The facts of the relativity of group characteristics can, of course, be confirmed with traffic simulation. Although traffic simulation could have been used for the systematic

comparison of groups with different configurations, it seems this possibility was overlooked. Presently, traffic simulations are primarily used to analyze the timedependent service qualities of specific groups. For more information on traffic simulation and/or comparisons of groups with different configurations, refer to chapters 10 and 8 of your author’s book at website: elevatorgroupcontrols.com.

Elevator Group Controls Traditional group controls with up/ down buttons on landings are still well known as a relic of the past. They have been succeeded by destination group controls. Destination group controls require passengers to register their destinations; the group control reacts by assigning each passenger to a specific car. This concept was invented during the 1960s by Leo Weiser Port. During the 1980s, these controls were reintroduced by Schindler on the basis of modern technology. Afterward, all major elevator

RTTs are equalized and minimized, all time-dependent performance parameters will reflect this quality (i.e., bandwidths will be as narrow as possible, and average parameters will be as short as possible). Minimized RTTs maximize transportation capacities and, consequently, minimize average car loads and their bandwidth. The discovery of the inherent relativity of group characteristics and the development of intelligent destination group controls has disclosed that the values and quality of group performance parameters can be controlled by a single criterion: the permitted number of stops relative to up and down traffic densities.

The Essence of Intelligent Destination Group Controls We can envisage the cars of a group of elevators as a string of cars that rotate in a building or building zone. Although the cars move independently in their own hoistways, they do form a virtual string of cars. An intelligent group control is the

transportation capacities, the string of cars will rotate faster, reducing travel times in the cars. Even for the most extreme up and down traffic densities, intelligent groups will ensure the shortest possible equitable time-dependent service qualities for all passengers. Fortunately, most of the time traffic is not heavy, enabling intelligent groups to concentrate on shortest possible consistent waiting times, in combination with shortest possible average times to destinations.

Direct Communication Between Passengers and Intelligent Controls Intelligent group controls will greatly benefit from direct communication between individual passengers and group controls. They will enable the control to welcome each passenger and identify the assigned car and the time period until it departs to the usual destination of a specific passenger. The passenger (i.e., an authorized building user) can change the destination and immediately get a revised

...the values and quality of group performance parameters can be controlled by a single criterion: the permitted number of stops relative to up and down traffic densities. companies have introduced proprietary destination group control systems. Unfortunately, the present generation of proprietary destination group controls is not intelligent, because they are not based on the inherent relativity of group characteristics.

Intelligent Destination Group Controls The preceding paragraphs should not leave any doubt that the values of group performance parameters depend on group configuration. The quality of these parameters depends on the artificial intelligence of group controls. This requirement enables defining the essential function of intelligent destination group controls to minimize and equalize the RTTs of all cars at all times. The quality of time-dependent performance parameters is defined by their consistency. For example: waiting times that vary from 0-100 s. do not signify high quality. This bandwidth is too wide. When

flexible virtual string that connects the cars, controls their positions and minimizes and equalizes RTTs relative to momentary traffic densities. Minimizing and equalizing of RTTs is achieved by control of the number of permitted stops relative to momentary up and down traffic densities. The total number of permitted stops for each round trip is defined by the total of momentary up and down traffic densities. This total number of permitted stops is divided pro rata to the momentary traffic densities and assigned to the up and down segments of the next round trip to control the travel times of up and down trips as required to satisfy momentary traffic densities. During periods of heavy traffic, intelligent controls must prioritize shortest possible average times to destination, and balance up and down transportation capacities. Although waiting times increase when permitted numbers for up and/or down stops must be reduced to increase

car assignment. Occasionally, a passenger may have to be informed of a change of the assigned car. Visitors must go to the reception/security desk for building entry. Early in the 20th century, this type of communication was the task of elevator attendants and supervisors. Presently, mobile phones enable a much better solution. Direct communication with individual passengers implies that intelligent group controls have complete data, in respect of the momentary requirements of all passengers (i.e., traffic conditions) at all times. It is obvious that building security systems can be greatly enhanced by intelligent group controls.

Interdependent Efficiencies of Vertical Transportation Efficient car operations imply that cars that complete their up trips earlier also ensure earlier service to down passengers. It is obvious that service qualities for up and down passengers are interdependent. Continued

The method to balance service qualities with the numbers of permitted stops for up and down trips also explains why intelligent destination groups can guarantee the best possible and most equitable service qualities for passengers in both directions under all traffic conditions. It also explains why intelligent groups can increase up and/or down transportation capacities at any time by reducing the number of permitted up and/or down stops. These control decisions increase the average waiting time; however, the travel time in the cars will be shorter, and the average time to destinations will be reduced, except for very few permitted stops.

Configurations of Groups with Intelligent Destination Controls Groups with intelligent destination controls are likely to have more and smaller cars. In-line car configurations will be attractive, because they save space and make it easier to plan groups with, for example, five or seven cars. All passengers will be aware of their assigned car and its time of departure. Consequently, their behavior will be relaxed. Short departure intervals and waiting times imply low numbers of waiting passengers, who distribute themselves throughout the lobby in accordance with car assignments. Car size does not affect time-dependent service qualities. If, for example, one or more cars of a six-car group must have a contract load of 1000 kg or more for requirements other than passenger transportation, this is completely unproblematic for intelligent group control. More and smaller cars may cause extra costs; however, efficient groups and exact planning of a new building will usually allow a building project to increase its rentable floor area and/or number of floors. Consequently, exact group planning is likely to make a building project more attractive and more profitable.

The Remarkable Efficiency of Intelligent Six-Car Groups Simultaneous up and down traffic is the most demanding situation for any group. The following example will demonstrate the performance of an intelligent six-car group for up and down traffic densities of 7% of the population per 5 min. This group serves a low-rise zone with 14 upper floors,

52

ELEVATOR WORLD India • 1st Quarter 2014 •

travel of 56 m, contract load of 800 kg, contract speed of 2.5 mps and population of 1,050 persons (75 per floor). For the assumed extreme traffic conditions, intelligent destination controls will permit only four additional stops during up trips to the top floor and only four additional stops during down trips to floor zero. This implies that during up trips, the cars serve five destinations, including the top floor. During down trips from the top floor, the cars serve four intermediate floors before arriving at floor zero. The top floor may also be read “reversal floor.” Under these conditions, the average car load, up and down, will be approximately six persons. The door-to-door flight time for a direct nonstop trip to the 14th floor and viceversa is 30.4 s. The additional stops during the up and down trips increase the RTT by 8 s. each, for a total of 64 seconds. The time cost for boarding and leaving the car is assumed to be 2 s. per passenger, for a total of 24 s. The average RTT will consistently be approximately 150 s. and the average interval between car departures will be approximately 25 s. During the consistent intervals, an average of 6.1 persons will enter the building (7% of 1050 = 73.5 persons per 300 s.; i.e., 6.1 per 25 s). On the basis of the mathematical formula for probable stops, these passengers have 5.1 probable destinations. This means that approximately 82% of incoming passengers can be assigned to the first departing car. Their average waiting time will be approximately 13 s. The other 18% of incoming passengers will be assigned to the second departing car that leaves approximately 25 s. later. Under these circumstances, upward cars will soon have an average car load of six passengers. Downward passengers have floor zero as their primary destination. We may assume they will experience average waiting and travel times not worse than those of upward passengers. During the extreme traffic conditions of our example, the waiting time bandwidth for all passengers will be approximately 40 s., with the average waiting time less than 20 s. The above data are conservative, because they assume the cars always reverse on the top floor. Also, the number of probable destinations for incoming

passengers is conservative, because the mathematical formula for probable stops assumes all floor populations and their working hours are identical. Consequently, the number of probable stops is most likely less than 5.1, and the time-dependent service qualities will probably be shorter than the calculated averages of this example. They will also be highly consistent.

Conclusions This article has proved that the configuration of a group defines its performance potential. Controls on the basis of permitted stops enable minimizing and equalizing of RTTs during all traffic conditions. Consequently, all service qualities can be optimized at all times. When a group provides outstanding service qualities to incoming and outgoing passengers during the heaviest upward and downward traffic, as demonstrated by the example, its service qualities during less-severe traffic conditions will not be worse. It should be noted that the inherent relativity of group characteristics makes the evaluation of group efficiency much easier.

Interlift 2013 Expo Biennial international trade fair continues growth in its 11th iteration. by Robert S. Caporale, MSc

As has always been the case in years past,

the most recent Interlift exhibition, held on October 15-18, 2013, at the Messezentrum in Augsburg, Germany, was a grand success for exhibitors and attendees alike. More than 500 exhibits were distributed throughout seven halls comprising 48,000 m2 of floor space, and it was reported that more than 70% of the 18,900 visitors came from overseas to attend the event and visit with their colleagues, make new contacts and take advantage of 48 VFA Forum educational sessions that ran continuously during exhibit hours. As pointed out by AFAG Messen Managing Director and head of the Interlift organizing team Heiko Konicke during the event’s opening session, “The worldwide elevator family sees Interlift as a reliable and indispensable marketing instrument and as an effective hub for qualified [elevator-industry] information and communication.” The activity seen in and around the exhibits, as well as throughout the VFA Continued Educational Forum, certainly bore this statement out. • Issue 1, Volume 7 • elevatorworldindia.com

The Messezentrum welcomes visitors and participants.

Opening Session Interlift 2013 opened with welcoming remarks by Konicke and VFA President Achim Hütter in a packed meeting room on the second floor of the Messezentrum Entry Building. An entertaining mime act was also provided by a very talented pantomime artist, who, along with an assistant from the industry, portrayed a very humorous rendition of a frustrated elevator passenger interacting with a modern high-tech elevator with voice-activated control features.

Innovations Abound The presentation of new technology always gets this reporter’s attention, and much of this was evident in many of the exhibit stands. A completely glass elevator car and hoistway enclosure with little to no supporting structure was a marvel to see. Numerous thin car and hoistway doors, both of a traditional design, as well as those completely made of glass, were brilliantly displayed. Additionally, large screens mounted inside elevator cars gave the impression and the feeling of traveling in an observation elevator, providing another surprising sensation. The next time anyone asks me, “What can be so special about riding in an elevator?” I will immediately direct them to www.elevatorworldindia.com’s Online Extras section, which displays the finely appointed and marvelous-looking elevator-car enclosures shown at this event. The Interlift exhibition has also become known as the place to see the latest technology applied to our industry’s equipment, and this year’s event certainly met this expectation. Large flat screens dominated many of the stands, where they were used to present videos and information on products offered by various exhibitors. Wittur even used vertically positioned screens to replicate an entire elevator entrance with centeropening door panels parting to display its various products. The most dynamic use of this technology inside an elevator car was displayed by DigiGage. Its system consisted of a 40-in. flat screen positioned vertically on the rear of a typical car enclosure interfaced with a mobile phone, from which the screen’s presentation was easily changed to show numerous scenes. For example, a beautiful underwater scene with tropical fish “swimming” outside and around the elevator cab was easily switched to a view of Times Square in New York City. Both scenes were synchronized with the car’s vertical motion as it traveled between two Continued

This system is a true marriage of elevator-industry technology and electronic social media that is so popular and effectively used in industry today. Also on display was a clever device that appeared to be just a conventional stair going up to a platform. In actuality, it was a dual-purpose accessibility device. At the touch of a button or turn of a key switch, the stair was gradually converted into an automated platform lift for use by disabled persons. Another interesting system on display was billed as the Automated Pedestrian Overpass.

The exhibitors and visitors we spoke with all seemed to be in agreement that Interlift 2013 was a grand success. Good business contacts were maintained and new ones made, educational sessions were abundant, and there were plenty of opportunities for attendees to see firsthand the latest technology the elevator industry has to offer. From all reports we received, exhibitors felt their expenditures made to participate in Interlift 2013 were very worthwhile, and the visitors were extremely satisfied with the event, as well. It is difficult for many in our industry to travel great distances to attend an industry event. However, if you can somehow plan enough in advance of the next Interlift expo and work it into your schedule to attend, you will find this event to be extremely worthwhile. The 2015 edition will again be held at the Messezentrum in Augsburg on October 13-16, 2015.

Common Misconceptions Regarding Elevator Traffic Simulations by Theresa Muenkel Christy Elevator professionals and elevator customers look to both traditional, formula-based elevator traffic analysis and sophisticated elevator simulation programs to evaluate potential and existing elevator performance with regard to appropriate traffic handling. Sometimes, the terms and concepts involved in such work are misunderstood or misused. This article discusses five common misconceptions in an attempt to clarify elevatoring concepts, unify terminology and explain tool limitations.

Introduction Elevator traffic simulations are frequently used by elevator professionals to evaluate proposed elevator configurations for new buildings or existing elevator configurations in standing buildings. In addition to building and elevator characteristics, these simulations require knowledge of the type and rate of elevator passengers as input and rely on specialized software to mimic the performance of elevators under the given input conditions. Elevator simulations can produce many types of output, including passenger waiting times and passenger times to destination, which allow the elevator professional to judge whether the elevator configuration can provide acceptable performance in the relevant building. Observation indicates many elevator professionals and customers interested in elevator performance, analysis and simulation do not fully understand the concepts used, and misconceptions are common. This paper describes five common misconceptions in an attempt to clarify various terms and situations related to elevatoring and elevator traffic simulations.

Number One: “‘Handling Capacity’ Is Simply How Many People Are Handled by the Elevator System in a Given Amount of Time.[1-4]” Handling-capacity calculations have been used as key elevator performance criteria for many years. Traditionally, handling capacity is a formula-based metric and calculated under very specific performance assumptions. Handlingcapacity calculations were used to determine how many elevators to put into a new building and to evaluate traffic considerations in existing buildings long before software-based elevatorsimulation programs were available, and they are still used today. Unfortunately, the historical term “handling capacity” has become confused with the newer term “arrival rate,” which is the term applied to the rate of passengers arriving in the elevator lobbies as input to an elevator simulation. Many individuals now use the two terms interchangeably, which can be problematic. Originally, handling capacity referred to the highest percentage of the building population the elevators could move in a 5-min. period, on average, given a specific set of building characteristics (e.g., number of floors in building and height of floors) and elevator characteristics (e.g., speed and size). Traditional handling capacity, due to the way it was calculated, was a steady state value, meaning that, in theory, the elevator system can serve the calculated volume of traffic for an ongoing period of time. Although handling capacity produces a steady state value, the calculated percentage is usually viewed as the peak capacity of the elevator system, and it was generally concluded that the peak capacity would only be reached for short periods of time Continued

each day, when numerous passengers all requested elevator service at the same time. Determining the correct number of elevators was based on determining whether the number of elevators being considered could produce the handling capacity needed to move the volume of people during peak elevator traffic. Elevator traffic simulation studies, which use specially designed software to mimic the performance of elevators in a virtual building, use input data to define how many passengers will request elevator service during the simulation period. The input is determined prior to the simulation execution, unlike traditional handling capacity, which is an output (not an input) of the relevant formulae. If an elevator professional designs a traffic input scenario that has a peak traffic of 10% of the building population, then execution of the simulation will output elevator performance metrics (e.g., average wait time) that can be used to determine whether the elevator system could handle a peak traffic of 10%. However, the results will not tell the professional whether 10% is the maximum the system can handle. If the elevator system can truly only handle a peak of 8% of the population, the simulation results with a traffic input pattern peaking at 10% will indicate that 10% cannot be handled. But, without further studies using different traffic inputs, the simulation only reveals that 10% cannot be handled; it does not indicate the actual maximum handling. Similarly, if the simulation results indicate the elevator system can handle 10% of the population, it does not automatically indicate whether it could actually handle more than 10% (or how much more than 10%). It is easy to see why the term “handling capacity” might be confused with arrival rate, because the goal of defining a handling capacity is often to design a system that can handle the peak amount of traffic. So, if a simulation illustrates that the peak traffic expected in a building can be handled by the elevator configuration design, an individual may be tempted to call that peak amount of traffic the elevator system’s “handling capacity.” The confusion comes into being when multiple individuals are discussing the same elevator configuration but some are using the term “handling capacity” to mean the maximum handling capacity of a system, and others are using it to refer to a rate of traffic expected to arrive at the building. These may not be the same thing. A further point of confusion is whether the expectation is for a calculated handlingcapacity value or a set of simulation results. To avoid confusion, it is recommended that the term “traditional handling capacity” or “calculated handling capacity” be used to mean the value calculated by probability formulae, the term “maximum handling capacity” be used to indicate the point at which an elevator system can no longer successfully handle additional passengers, and the term “arrival rate” or “demand rate” be used to indicate the flow of passengers used as input to an elevator simulation.

Number Two: “Increasing the Elevator Speed Will Provide Better Service.” Increasing the speed of an elevator will sometimes provide better service, but there are many times when it will not. If an elevator frequently travels through a long express zone, it is probable that increasing the speed of the elevator will give passengers a faster ride, and it will take less time to get to waiting

hallway passengers. But, if the elevator makes frequent stops at floors near each other, then changing the speed may have little or no impact on the service. This is because when an elevator moves short distances, it does not have time to get to full speed. Elevators need to accelerate when leaving a stopped position and decelerate when arriving at the target floor. If the distance between the original and subsequent stops is short, the elevator may need to start decelerating before it has completed the full acceleration phase and reached full speed. For example, if an elevator travels 4 m from a stopped position to a stopped position with a motion profile of 2 mps, 1 mps2 acceleration and 1.6 mps3 jerk, it will take the elevator approximately 4.5 s. to move from the first to the second position (assuming no start or machine delays). The highest speed the elevator will achieve is approximately 1.4 mps. If the speed of the elevator is increased to 3 mps, it will still take the elevator approximately 4.5 s. to cover the distance, and the highest speed it achieves will remain at 1.4 mps. Therefore, increasing the speed from 2 to 3 mps offers no performance advantage when the elevator travels short distances. An elevator that travels 8 m with a speed of 2 mps (and other parameters held the same as the previous example) will take 6.4 s. to travel the distance, whereas increasing the speed to 3 mps will allow the elevator to go from start to stop in 6.1 s., a savings of 0.3 s. The distance of 8 m allows the elevator to achieve full speed, if only for a short time, when using a contract speed of 2 mps. When using a contract speed of 3 mps, the elevator starts to decelerate when it reaches a top speed of 2.2 mps and does not reach full speed. However, the longer distance of 8 m is still not sufficient distance to make a difference between elevator speeds if the speeds in question are 7 mps and 8 mps. In this case, neither motion profile would allow the elevator to reach full speed in 8 m, and there would be no performance difference between an elevator traveling 8 m at 7 mps, as opposed to one traveling 8 m at 8 mps. As with the 3-mps case, the elevator traveling at 7 or 8 mps starts to decelerate once it reaches the speed of 2.2 mps and does not have enough acceleration time to reach full contract speed.

Number Three: “The Description of “40-40-20” Tells Everything One Needs to Know about Elevator Traffic Input.[5]” Elevator traffic is frequently described by a series of three numbers, the most common of which are “40-40-20” and “45-4510.” The first number refers to the percentage of passengers traveling up from the lobby, the second number refers to the percent of the passengers traveling down to the lobby, and the third number refers to the percentage of passengers moving “interfloor,” such that neither their origin nor destination is the lobby. The three numbers must sum to 100%. This three-number shorthand is an excellent way to describe the percentages of each type of elevator traffic, but it does not indicate the duration or quantity of the traffic. Therefore, it is easy to misinterpret. Sometimes, individuals, upon being asked to set up a “40-40-20” traffic-simulation scenario, automatically assume the simulation should use a traffic pattern that moves 40% of the building’s population up from the lobby in 1 hr., 40% of the building’s population down to the lobby in 1 hr. and 20% of the building’s Continued

population from one non-lobby to another non-lobby floor in the course of the same hour. While this might seem to be a good guess, “40-40-20” actually refers only to the destination percentages of the people being moved, not to whether the distribution is moving all of the building’s population or some percentage of the building’s population. Neither does “40-40-20” give the timeframe over which those people will use the elevators. In order to accurately depict a traffic distribution to be used for a simulation, the “40-40-20” phrase needs to be used in conjunction with a number of people or a percentage of the building’s population, together with a timeframe. For example, it is appropriate to say, “Move 10% of the building’s population in each of 5 min. for a 45-min. period using a ‘40-40-20’ configuration,” or, “Move 550 people evenly over 30 min. using a ‘45-45-10’ configuration.” The first example means that if you have a building with 1,000 people in it, then in each of nine periods of 5 min. each, there will be 100 people attempting to use the elevator (10% of 1000). 40% of those 100 people (i.e., 40 people) will be attempting to travel up from the lobby, another 40% of those people will be attempting to travel down from the lobby, and 20% of those people (i.e., 20 people) will be moving interfloor. The second example means that if you have a building with 1,000 people in it, then only 55% of the population, or 550 people, will be using the elevator system over 30 min. Dividing 550 by six (the number of 5-min. periods in 30 min.) means that approximately 92 people will desire elevator service in each of those 5 min. Using the “45-45-10” configuration, 45% of those 92 people (i.e., approximately 42 people) want to travel up from the lobby, 45% (i.e., approximately 42 people) want to travel down to the lobby, and the remaining 10% (i.e., approximately nine people) will be moving interfloor.

Number Four: “Automated Elevator Monitoring Systems Are Great, Because They Can Tell You How Long People Wait for Elevators.” This misconception applies mainly to automatic systems used to monitor traditional two-hall-call-button elevator configurations. Automatic elevator monitoring systems can be installed in most modern elevator environments to automatically and routinely collect and tabulate data related to elevator performance. These systems can be very helpful tools, but only if understood and used correctly. Elevator monitoring systems can only track elements that have a mechanical or electronic component that can transmit information to the computer running the monitoring system. The time an elevator reaches a floor, the number of buttons pressed on a car-operating panel, and the time and location of an up hall call button being pressed, for example, can all be monitored. The weight of an elevator car can be monitored and, perhaps, used to estimate the number of people in the car. But, with the exception of destination-entry systems (in which each passenger indicates destination with an electronic device), the number of passengers waiting in the hallway for an elevator car is not monitored. Elaborate camera, video or radio-frequency identification tracking mechanisms that might allow for passenger tracking are currently too expensive for routine use in elevator performance monitoring.

The result of elevator monitoring limitations is that elevator monitoring systems track elevator response time, the elapsed time between a hall-call button being pressed at a floor and the arrival of an elevator to serve the demand at that floor, but cannot track passenger waiting times. A passenger’s waiting time is the time between the passenger’s arrival in the elevator lobby until the elevator that will serve him or her arrives. It is easy to confuse the elevator response time with the passenger waiting time, because the time value is often the same for both the elevator and the person who actually presses the hall-call button. A classic mistake in the use of automated monitoring systems is made when an evaluator looks at the automated monitoring report, sees that the average “wait” time is about 30 s. and assumes the elevator service is good. Although most systems report “wait” time, the systems are not really reporting passenger waiting times, but rather elevator arrival times. Even if the metrics are correctly labeled as “response times,” many evaluators assume that is the same as waiting times. If there is only one passenger waiting, then the elevator arrival time (difference between hall-call button being activated and elevator arriving at the floor) and the passenger waiting time (difference between passenger arriving in hallway and passenger entering elevator) are, basically, the same thing. However, consider a situation where the first person arrives in the hallway and presses the hall-call button, then a second person arrives in the hallway 10 s. later. The elevator then arrives 20 s. later. Elevator arrival time is 30 s., as is the waiting time of the first

passenger. The second passenger, however, has a waiting time of only 20 s. The average wait time of these two passengers is 25 seconds, a bit less than the reported “wait” time, which is actually the car arrival time of 30 s. The waiting-time discrepancy described above overstates the actual average waiting time and may not be seen as a big problem. The real problem occurs when there is queuing, a situation where not all of the people waiting in the hallway can get into the next arriving car. In this case, the elevator arrival times will be reset each time an elevator arrives at the floor, but the actual passenger wait times for those passengers left behind will continue to accrue. This means the reported “wait” time from an automated monitoring system can seriously underreport waiting times during peak elevator traffic when queuing occurs. If the elevator performance is evaluated from the reported wait times under these conditions, the evaluation may be significantly incorrect.

Number Five: “It Is Easy to Figure Out a Building’s Traffic Pattern When You Have an Automated Elevator Monitoring System.” It would be great if this were true, but usually, it is not. As described in section “Number Four,” automated monitoring systems are limited in their ability to track individual passengers, especially in conventional two-hall-call-button systems. In a two-button system, only the first passenger arriving in the hallway going in a specific direction presses the hall-call button. Therefore, the monitoring system cannot know whether there is one person waiting for the elevator or numerous people waiting.

Even after the waiting passengers get into the elevator and press the car-call buttons inside the car, it is difficult to know how many people entered the car and how many were left behind in the hallway because the car was too crowded. Only the first individual going to a specific floor will be registered as pressing the car-call button for that floor, and if that button had already been pressed prior to the car’s arrival, another button push will not be registered. Therefore, the monitoring system has no way to precisely determine how many people entered the elevator or where each of them is going. Arrival rates and passenger-specific origin/destinations combinations are key factors of a building’s traffic pattern. Automated monitoring systems (which count hall calls, car calls and car arrival times, and cannot track per passenger arrival times, car entry times or destinations) cannot easily produce accurate building-traffic patterns. In a destination-entry system, it is more likely that the automated monitoring reports will be more correct. This is because in a destination-entry system, each passenger is expected to use the destination-entry device, and the system will be able to monitor each passenger’s arrival time, origin floor and destination floor at the entry device. However, it has been consistently observed that in actual practice, some people do not enter their destination, relying instead on destinations that have been entered previously or by someone else in their group. Also, some individuals enter their destination multiple times in the hopes of an elevator arriving more quickly and/or a less crowded elevator. In a destination-entry system, the more people who use the system

contrary to its design (i.e., where each passenger enters one and only one destination), the less accurate any traffic pattern determined by monitoring destination entries will be.

Statue of Liberty Upgrades Life and Safety Upgrades for the iconic U.S. structure entail great ingenuity to overcome unique challenges.

by Douglas J. Muttart and TinaMarie Cortina The Statue of Liberty is synonymous with American freedom. When the terrorist attacks of September 11, 2001, occurred, that freedom was visibly shaken. Despite those horrific events, Americans emerged with a sense of resilience and determination reflective in our nation’s history of prevailing under the direst of circumstances. Throughout the chaotic few months that followed, Lady Liberty stood tall as a constant reminder that we would persevere. Due to increased national security following the terrorist attacks, the statue was closed for three years. Only in 2009 was its crown reopened to the public. In an effort to make the statue a safer and more accessible attraction for visitors, Ken Salazar, former secretary of the interior, vowed to continue upgrading the interior systems and bring them up to current code. In 2011, the request for proposal for the Statue of Liberty’s Life and Safety Upgrades was announced. This comprehensive upgrade included wider stairways, upgrades to the fire-suppression systems, and a complete overhaul of the vertical-transportation systems. This included removing the existing doubledeck hydraulic passenger elevator and replacing it with a new machine-room-less (MRL) passenger elevator, installing a new Americans with Disabilities Actcompliant handicapped lift and installing a state-of-the-art emergency rack-and-pinion elevator. All elements of this project were required to adhere to a strict “Buy American” policy. This meant that every nut, bolt and screw had to be derived from facilities in America.

Joseph A. Natoli Construction Corp. was awarded the project as the general contractor and was overseen by Atkins Construction, North America, which was in charge of the overall construction management by the National Park Service. When choosing its prime elevator contractor, Natoli understood the importance of choosing a company with a reputable history and the required experience needed to construct within the preexisting conditions of a national landmark. Liberty Elevator Corp. was chosen for the job, in part because 25 years prior, Douglas K. Muttart, late father and husband of its current owners, Douglas J. Muttart, Darren Muttart and Janet Muttart, installed the original passenger elevator for the 1986 Liberty Weekend; at the time, this was the largest double-decker hydraulic elevator in the U.S. Liberty faced several challenges in creating and implementing its custom design plan. Advanced computer simulation provided by its engineering and manufacturing groups was utilized to assist with the design of a custom passenger elevator. The entire


monument was also surveyed using precision-based 3D laser technology to ensure no element was overlooked. This high-profile project brought logistical and technical challenges: because Lady Liberty resides on an island, all of the materials had to be delivered by boat. Careful planning and project management were required to ensure the delivery and installation of materials would proceed without disturbance. It also had to be remembered that, although Lady Liberty has stood tall for over a century, the wind stress actually sways the entire structure: with a 50-mph wind, it sways 3-5 in. Not only was it required that every component of the elevator system be American made, they also had to comply with strict specifications that could not be altered. These included the design, manufacture and construction of a passenger elevator that could accommodate a stretcher, without any room to widen the shaft, change the overhead or reduce the interior dimensions. Liberty quickly began brainstorming with Elevator Doors, Inc./Elevator Cabs, Inc. (EDI/ ECI) and Motion Control Engineering. EDI/ECI and Liberty had the unique advantage of having collaborated on the design and implementation of the original 1986 elevator. Together, they were able to design a revolutionary Freedom® MRL elevator package that complied with the guidelines put forth by the U.S. National Park Service and boasted a regenerative drive that performs on 60% less horsepower than the original elevator. The pedestal elevator was only one-third of the entire vertical-transportation work. For the first time in the structure’s history, handicapped visitors would be able to access the observation deck on level 6P. Kamran Shushtarian, owner of Mobility Elevator & Lift Co., comments, “It was a very moving experience

For the second time in 25 years, Liberty, EDI/ECI and VDA had the honor of joining forces to supply Lady Liberty’s verticaltransportation needs. Here, in front of the doors at the monument’s entrance, which illustrate the 1986 installation, are (l-r) Ahmet Tanyeri, VDA; Chris Taukus, EDI/ECI; Hakan Tanyeri, VDA; and Doug Muttart, Liberty.

when I watched a local news program covering a handicapped individual using the wheelchair lift and having access to our most cherished symbol of freedom.” Additionally, a new emergency elevator replaced the existing obsolete elevator to allow injured visitors a safer and more efficient means of being transported out of the statue. The emergency elevator is strictly for emergency personnel and maintenance activities and is the only elevator installed within the body of the statue. The elevator was installed adjacent to the spiral staircases, allowing emergency personnel to reach distressed visitors at four intervals along the route. With a carrying capacity of three people, it provides an enhanced safety feature, which allows the visitor to be transported safely to the main elevator for complete egress from the monument without having to navigate the stairs. Todd Grovatt, president of Tower Elevator Systems, Inc. (TESI), which manufactured the rack-and-pinion lift, explained: “One of the major challenges of the project was the incredibly tight space inside the statue. It required a highly innovative and customized design, making Continued

sure the system attached to the exact same points as the old elevator, with no modifications to the historically protected interior statue structure. Our rack-and-pinion technology allows the flexibility for an elevator to be placed just about anywhere you can mount the hoistway gear rack. The rescue elevator was custom designed specifically for this application and location. It is the only elevator of its kind in the world.” With Van Deusen & Associates (VDA)’s approval and oversight, Liberty chose what it felt were the most motivated, advanced and trusted American manufacturers. As stated by Doug Muttart, Liberty president: “The fact [there] are three different father and son firms with direct association to Lady Liberty, spanning two generations, is a testament to the gift a parent can pass down to [his or her] children and how proud a son can make his dad. All I can say is, ‘Thank you, Dad, I wish you were here to see it completed again, and sorry we had to rip your old elevators out, but Darren and I needed to do the project one more time.’” This comprehensive vertical-transportation project required the thoughtful and creative planning, design and execution by a team of seasoned, yet innovative, elevator professionals. Liberty was able to assemble a team to accomplish this, from start to finish, in 13 months. When Liberty learned of the intent to remove Douglas K. Muttart’s double-decker hydraulic elevator, brothers and current Liberty owners Doug and Darren Muttart understood the significance of their father’s legacy. The end result was three new elevators worthy of allowing visitors to experience Lady Liberty well into the 21st century.

Bottom right: Douglas K. Muttart standing along the National Elevator Corp. vehicle onsite during the 1986 installation of the first elevator in the Statue of Liberty.

The Pedestal (Main Passenger) Elevator The main elevator was replaced with an MRL elevator boasting a regenerative drive and the ability to transport passengers at 200 fpm. As the elevator car decelerates, excess power is filtered and returned to the main power line for use by other electrical loads within the Statue of Liberty. The 2500-lb.-capacity unit travels from levels 1P–5P, a distance of 115 ft., 1-3/4 in. There is an escape hatch in the rear panel of the cabin designed specifically so the interior ventilation equipment for the monument can be accessed for maintenance. The elevator provides for freedom of choice for the U.S. National Park Service, as all parts are nonproprietary, and there are no restrictions on maintenance material or technical support. In addition to all structural steel and hardware materials being U.S. products, all structural-material fabrication was performed in the country.

Handicapped Lift A new handicapped lift was additionally installed. This lift travels from levels 5P-6P and is meant solely for handicapped visitors. This provides a travel distance of approximately 14 ft., 9 in. Most other wheelchair


lifts are limited to 12-14 ft. of rise. This limited-use/ limited-accessibility lift has a 750-lb. capacity.

Emergency Elevator The existing emergency elevator was replaced with a 750-lb.-capacity rack-and-pinion elevator for emergency use. It travels at a rate of 150 fpm and distance of 89 ft., 8 in. to levels 6P, 4S, 5S, 6S and 7S. This system offers unique safety features, including the “Full Height Hydraulic Rescue Lowering System” (U.S. Patent No. 8191689, “Rescue Lowering”). This allows the self rescue of a stranded rider from any height without having to stop to cool the brakes (like old centrifugal systems). Laser positioning, closed-loop feedback and a touchscreen car-operating panel are key elements of this elevator. TESI’s gear-driven rack-and-pinion technology allows for an elevator to be placed nearly anywhere the hoistway gear rack can be mounted and minimizes impact on the support structure. The custom elevator will also be used to provide emergency personnel alternate access without having to use the stairs.

Standardization, Harmonization and IP The prime requirements for Indian micro, small and medium enterprises (MSME) to achieve quality, productivity and competitiveness by Trivedi Pankaj The growth rate of the Indian elevator industry is very high. Every day, change comes to the market, bringing with it new challenges. In earlier days, it was difficult to import elevators and their components from other countries; there were very high cost and border barriers due to transportation and information limitations. Now, however, the world has become so small, and border barriers are diminished, with existing limitations to be abolished soon. Within a very short span of time, the total import/export market will be different than today. A huge opportunity for exportation will be available, and importation will become very easy. There will be very insignificant import/ export restrictions and duty rates for products to enter India, and transportation and exportation will become completive due to the availability of more bulk. The Indian elevator industry is on a smaller scale than that of such countries as China. Are we prepared for quality and service competition against foreign companies, and are we able to continue our exportations with our standards of today? The Indian elevator market has a large list of world-class options from which to choose. Monopolies are no more, and the customer has become very wise, in terms of knowledge for quality and prices. We also can observe that, while in an early age, the customer was looking at only the cost of the product, now, cost, service, quality, reliability, safety and many other factors have become criteria. Also, in early times, the market outlet was a shop or showroom; today, it is a website. This means the market is becoming complex for the Indian manufacturer, and it is going to become very

difficult for manufacturers to sustain if we do not take appropriate steps. India’s business has a different pattern than that of other countries, though there might be similar models in the world facing similar problems. Manufacturing, selling, sourcing, transporting, banking, etc. are divided into very small parts, resulting in a small scale. These challenges are mostly for medium- and smallscale enterprises. Any Indian business has either routed or is dependent on MSMEs. To maintain their product/component share in their home market, Indian manufacturers have work to do in quality, process, establishment, administration and psychological aspects. This means drastic changes are required. The area where India is seen to be lagging behind other countries is product quality. Excellence is a mindset, and we do not have enough of it. We tolerate a lot of nonsense, and it permeates into a lot of what we think is acceptable. We must be unwilling to accept less. The general belief is that we cannot compete with the quality of our foreign counterparts. But, this is not so; normally, an Indian manufacturer makes two types of qualities: one for exports, which is at par or better than its competitions, and the other for local supply, which is very cheap and competes with the junk from China. Everybody knows we have the brains – worldclass software companies are from India. Most of our pharmaceutical companies are U.S. Food and Drug Administration-approved, which is supposed to be the best quality mark. Reliance Chemicals is at the world level. For motorcycles, we have Hero, Bajaj Auto, TVS Motors and Continued other giant suppliers.


Though manufacturers may wonder why they should export products when we have a huge domestic market, since our domestic market is also open to the world leaders, everybody has to be prepared to compete globally. To reach this market requirement, manufacturers should upgrade their present level to the international level to enable their products to compete in both local and international markets. This requires developing and following standards, with each process (regardless of size) having its own quality, testing and safety standard. Each product is required to be harmonized, so that interchangeability, quality standard and testing criteria can be set and followed.

facility centers for standard development, prototype manufacturing and testing of criteria for quality and durability standards.

Though manufacturers may wonder why they should export products when we have a huge domestic market, since our domestic market is also open to the world leaders, everybody has to be prepared to compete globally.

Code Standardization

If we study the supply of foreign machinery, it is composed of various sub-modules or -assemblies outsourced from specialized/ established manufacturers. This system of production ensures product quality, as particular manufacturers have specific products and less variety to dilute their concentration. In addition to promoting expertise, this enables such manufacturers to produce in greater quantity, as everybody will procure a certain material from only a few manufacturers. Producing in bulk allows for planning in advance and the buying of raw material in bulk, which ensures lower production costs. Manufacturers can afford to maintain service staff and provide product guarantees.

Adopting Higher Standards The steps by which to adopt higher standards can be divided into the following different levels: 1) Individual 2) Association 3) Firm 4) Government

Individual All MSME manufacturers should start adopting ethical standards: products manufactured must be safe to sustain, perform the best, be more efficient, last long, consume less energy, not be only for profit, not be falsely promoted, be supported in the field by the sharing of knowledge and many more.

Association All manufacturers that are in the same and similar segments of product manufacturing should be associated. To begin, they should not consider each other competitors; they should associate and provide a common platform for their product or segment. Major activities should be an improvement of product quality; standardization; study of global trends; and quality standards, harmonization of components to reduce costs, set up common

Firm There are many advantages to sustaining a product in the market. These include proving reliability (creating assurance in the market) and branding. Without sustainability, a product will have a presence in only a limited market, both in terms of location and quantity. If a product is branded and registered, the manufacturer will have the legal right to use it across the globe without fear of it being copied by others. This will promote brand identity, providing a consistent, long-lasting benefit of selling in the market. If a firm is following a code like IS 9001-2008 and is certified, its customers will have very good faith in its product, management and records, because they are ensured that the company can provide management-system-related help at any time. This will also help the firm improve management culture and will lead to fewer failures and greater efficiency.

Quality-Assurance Certifications If a product is certified by a third party, agency or government body for compliance to quality standards, customers will have better faith in it. Quality certifications like the National Standards Body of India, Comité Européen de Normalisation, Underwriters Laboratories® and many more can be adopted. This will lead to improvements in product quality at a global level. The product will be able to compete with imported ones, and it will have standings in the export market, too.

Ratings Financial status and other business criteria should be examined by authorized rating agencies, to evaluate companies’ performance capability and financial strength. This will help manufacturers get better financing from financial institutes and also convince customers of their status.

Lean Manufacturing Practice The Lean Manufacturing Practice is a total manufacturing environmental concept, which can lead to a boost in productivity, maximization of space utilization, time management and process modernization. Such methodologies as 5S, Kaizen, Visual Control Management, Material and Employee Movement Reduction, Mistake Proofing and Total Productive Maintenance can change entire identities of a manufacturing unit, benefitting the environment, products and productivity.

Testing Facility An in-house testing facility will lead to very high product confidence. It will minimize failure rates and also make manufacturers able to deliver safe products to the market. To match any Indian or world-quality standards, it is required to have relevant and state-of–the-art testing.

first-generation entrepreneurs in realizing their dream of setting up their own MSMEs. Keeping this objective in view, the Government of India’s Ministry of MSMEs has launched the Credit Guarantee Scheme (CGS) to strengthen its credit delivery system and facilitate credit flow to the MSME sector. To make the scheme operational, the Government of India and Small Industries Development Bank of India have set up the Credit Guarantee Fund Trust (CGFT) for MSMEs. When securing financing, the main objective is that the lender gives importance to project viability and secures the credit facility purely on the primary security of the assets financed. Another important objective is the lender’s guarantee to give composite credit to the borrowers so the borrowers obtain both a term loan and working capital facilities from a single agency. The CGS seeks to reassure MSME lenders that availed collateral-free credit facilities discharge their liabilities to the lender. Otherwise, the CGFT would make good the loss incurred by the lender up to 75%, 80% or 85%.

IP Manufacturers should take advantage of intellectual property (IP) rights. These include patents, copyrights, industrial design rights, trademarks, trade dress and trade secrets. This will strengthen their businesses.

business-to-business exhibitions. Many other governmental departments are helping for raw-material purchase, funding and many more aspects favorable to MSMEs. Recently, Parliament passed a resolution for the MSME segment that all public-sector undertakings and semi-government companies must buy at least 20% of their total purchases from MSMEs. This is going to become a very supportive step from government, because total value of this business will be very big.

Conclusion Ninety-nine percent of the Indian elevator industry is made up of MSMEs. Having recognized this, the central and state governments of India are promoting many activities; arranging road shows and seminars; and providing funds, loans and subsidies for these enterprises. Manufacturers should update themselves by visiting government websites for related topics, and finding where the helping hand is available.

Daily Traffic Profiles The traffic patterns of hotels and residential buildings is examined in this revisiting of Strakosch’s analysis. by Dr. Marja-Liisa Siikonen, Janne Sorsa, Juha-Matti Kuusinen and Henri Hakonen Traffic patterns for morning up-peak, lunch hour and daily traffic are simulated to determine passenger-service levels during traffic peaks and throughout the day. In the latest publications on traffic simulation, attention is mostly paid to elevator traffic performance in office buildings. In 1976, George Strakosch[1] published profiles for 10- to 12-hr. daily traffic in offices, parking structures and garages, shopping centers, hospitals, schools, hotels/motels, apartment buildings and dormitories. His method was to count people entering and exiting elevators in main lobbies. Since then, no new traffic profiles have been published, except for office buildings. This article studies whether the Strakosch profiles are still valid today by comparing them to recent traffic measurements in buildings in Europe, North Africa and the Far East. It also reviews current planning practices of hotel and residential-building elevators against the measured data.

Traffic Measurements The recent traffic measurement used three methods.[5] First, an external device counted the people from photocell cuts on every floor.[2] Each passenger was assumed to produce two photocell cuts, one each when entering and exiting the car. The second method was based on a control system, which counted the number of passengers entering and exiting per floor and direction at every floor throughout the day.[3] It used a car-load weighing device and photocell signals to count the passengers. The first two methods are capable of detecting interfloor traffic. The third method was manual counting of people in and out the elevators at the main lobby.

ELEVATOR WORLD India • 1st Quarter 2014 •

Measurements were conducted in hotels in Finland using method 1, Egypt and the U.A.E. using method 2 and Singapore using method 3. The measured hotels had four- to five-star ratings. The estimated number of hotel guests was 170 in Finland, 490 in Dubai, 700 in Singapore and 1,240 in Egypt. In the population estimation, occupancy per room was assumed to be 1.7 persons. Traffic in residential buildings was measured in Finland and Singapore using method 3, France using method 1 and Hong Kong using method 2. The population was estimated from the rooms by assuming two persons in the first bedroom and one person in each additional bedroom. The estimated number of occupants in Finland was 100, in Singapore 400, in France 500 and in Hong Kong 760. Individual measurements were combined into a worst-case profile. In the profile, the maximum arrival rate of the four measurements and the average of the traffic components were calculated for each 15-minute interval of the day.

Hotel Traffic Profiles The Strakosch hotel/motel profile in Figure 1 shows a traffic peak from 8-9 a.m., when people go to breakfast and return to their rooms. Other peaks occur during the noon lunch hour, when people check in and out in the late afternoon, and in the evening at dinnertime. An accumulated hotel profile based on the original two-way profile is also shown in the figure. According to this profile, the highest traffic peak of 10-11% of the number of hotel guests in 5 min. occurs at 5 p.m., when people check in and out and prepare for dinner. Continued


The measurement results and the Strakosch profile are depicted in Figure 2. In the profile estimated from the measurements, there are two traffic peaks: one in the morning and the other at about 5 p.m. The inter-floor traffic is caused by the common floors, including gyms, restaurants, meeting rooms and businesscenter floors. The maximum arrival rate was 9.5% of the population in 5 min., which is a bit lower than the highest peak in the Strakosch profile. The measured morning peak, however, is a bit higher, since nowadays, people check out mostly in the morning. Otherwise, the two profiles are in line with each other. Figure 1: (Top to bottom) Strakosch traffic profile for hotel/motel and an accumulated profile

Figure 2: Measured daily traffic profile and total arrival rate of Strakosch profile of hotels; traffic stacked in 15-min. intervals

Traffic Profiles of Residential Buildings The Strakosch apartment-building traffic profile is presented in Figure 3. It has three peaks: one at noon during lunch hour, another at 3 p.m. when children return from school and a third at 6 p.m. when people return from work. The peak heights are a bit more than 7% of the population in 5 min. In the morning, there is mainly outgoing traffic: otherwise, the traffic is more or less two way throughout the day. Figure 4 shows the worst-case profile of the measured buildings and Strakosch profile. The measured traffic was two way throughout the day. There is a down peak in the morning and somewhat more incoming traffic in the evening. The portion of inter-floor traffic is almost negligible. The traffic intensity is lower than measured by Strakosch, the maximum being 5.7% in 5 min. The 15 intervals in the measured profile somewhat flatten the peaks compared to the 5 min. interval. The measured profile does not show the lunch and “children home” peaks. “Work over” and “children back from school and hobbies” occur from 4-6 p.m. These timings likely depend on the culture.

Current Planning Practices for Hotels and Residential Buildings

the selection of guest lifts is based on two-way traffic analysis. In the planning, 40-55% of the car-load factor should be used instead of 80%, since guest luggage reduces available space. Handling-capacity criteria is in the range of 12-16% in 5 min. In resort hotels and motels, handling capacity of 10% in 5 min. is acceptable. Hotel population is usually estimated at a density of 1.5–1.9 guests per room.[4] In Figures 2 and 4, the population defined at the planning stage was used to scale the measurement results, since the real population at that time is unknown. The population estimation affects the scaling of the traffic peaks from the absolute number of persons to the percentage of population. The measured traffic peaks were about 9-10% in 5 min. During the measurements, however, the hotels were not fully booked. With maximum occupancy, peak arrival rates can reach well over 10% of the population in 5 min. According to the measurements, there is about 40% incoming and outgoing traffic and about 20% inter-floor traffic. The amount of inter-floor traffic depends very much on the floor arrangement and the culture. The current hotel criteria do not take into account the interfloor traffic but could be considered in the future. In selecting the elevator arrangement for low-rise apartment buildings, the best practice is to follow local standards. The population can be estimated from the number of bedrooms, usually assuming

1.5–2 persons in the first bedroom and 1-1.4 persons in additional bedrooms. Strakosch[1] suggests 20 m2 of net area per person when the residential floor layout and utilization is unknown, or 1.5-2 persons per bedroom. Normally, two-way traffic in apartment buildings is assumed in elevator planning, and handling capacity requirements vary 5–9% in 5 min. These requirements match the measured daily traffic profiles. At the planning stage, the same 40-50% car-load factor could be used (instead of 80%). The extra space is needed for baggage, baby carriages and other objects transported in residential-building elevators. At the moment, there are no specific criteria for the car-load factor in residential buildings.

Conclusion The suggested traffic profiles do not include any measurements from the U.S. The Strakosch hotel/motel profile, however, highly resembles the measured hotel profiles. In the residential traffic profiles, there are differences in the midday traffic, which can be explained by changes in people’s living habits over the last 40-50 years. The measured profiles more represent today’s traffic, and these can be used as templates for hotels and residential buildings if accurate traffic is unknown. Exact figures for the given profiles can be found in “Traffic Patterns in Hotels and Residential Buildings.”[5]

With Xizi Noiseless Brakes, working air-gap noise stays below 58dB, reducing air-gap noise by 50% compared with conventional brakes under the same load. The brakes are attached to the outside of the traction machine for easy service and replacement. The integrated brake-releasing limit ensures operational safety in addition to the application of high-quality noiseabsorbing elements for more than two million times, and vibration-damping materials for over three million times. The air-gap protection level is raised to IP42, up from IP40. Having undergone more than two million energy-absorption tests, the new brakes promise a desirable, long working life for users. www.xizielevator.com

Controls for Escalators

Xizi Escalator Controls (IC/GC series) feature redundancy designs for safety and reliability. The integrated MSC board works by two CPUs and a set of 32-bit memory to achieve eight safety functions, meeting the SIL2 safety perfection level with zero failure rate. The eight functions check against over-speed and respond before the rated speed is exceeded by 20%; against unintentionally reversing travel; whether the braking distance keeps within 1.2 times of the allowed value; whether the secondary brake is functioning properly; against any missing steps and/or comb plates; the handrail belt speed against any deviation greater than 15% from the rated value for more than 15 s.; the opening of the operational brake; and the opening state or removal of any cover plates for service purposes in the truss zone. The control over the secondary brake allows a power-off delay to prevent the escalator from making any emergency stops that are too abrupt for passengers, while the value setting and self-learning ability makes field installation easy. www.xizielevator.com
