FROM THE EDITOR

FROM THE EDITOR TECHNOLOGY IS CHANGING EQUIPMENT PURCHASING DURING COVID-19

T

he process of buying equipment has been steadily evolving through recent years. There is still a strong appreciation for walking into the dealership, sitting in the operator’s seat and discussing the benefits of a new piece of machinery with a dealer expert, of course, and that’s not likely to go away any time soon. However, our last year of lockdowns, closures and disruption to the way we do things has meant shifts in many peoples’ approaches to purchasing.

Manufacturers have reported slowdowns in the purchase of new equipment through 2020, but the construction industry has maintained a steady level of operation with new health and safety requirements in place. Equipment still needs to be replaced, new machines are needed, and work needs to continue. That seems to have driven an interest in the secondary market for heavy equipment – and driven further development of online purchasing.

Here’s a good example of how equipment purchasing seems to be shifting: the auction market. Ritchie Bros. runs auctions across several continents on a regular basis that draw thousands of buyers to bid on machines of all kinds. Their auctions are huge events – and they slammed to a halt in the wake of the coronavirus pandemic.

While one might think that would impact sales, the fact is that while live auctions have ceased for the time being, they were quickly replaced with online bidding, something Ritchie Bros. had been working with prior to the pandemic. The company had been investing in technology for quite some time, and had focused in on it with online auction events and similar activities over recent years, so it was immediately decided to move all of their activities to 100 percent online, using mobile apps, timed auction systems and other approaches to keep the sales channels open.

I think it has been well established that the construction industry has traditionally been somewhat resistant to adopting technology, but that the past few years have seen a greater acceptance. That was immediately obvious to Ritchie Bros., which saw a significant increase in bidder registrations and users taking advantage of various online tools the company has established. The company also noted an increase in used equipment prices – about two percent in the three months ending in December of 2020.

With uncertainty remaining surrounding COVID-19 and continuing lockdowns around the world, Ritchie Bros. says

Equipment still needs to be replaced, new machines are needed, and work needs to continue. That seems to have driven an interest in the secondary market for heavy equipment – and driven further development of online purchasing. it is planning to stay 100 percent online for the foreseeable future. With buyers willing to purchase heavy equipment online that’s no real surprise, and I suspect we’ll see more moves to increase online purchasing options for heavy equipment moving forward.

I would not be surprised to see many other moves to shift heavy equipment purchasing – both used and new – toward remote purchasing. The construction industry is becoming faster to accept technology, and this year’s pressures may just accelerate that acceptance. This year could bring even more changes in how construction equipment is purchased.

heavyequipmentguide.ca | FEBRUARY 2021

eveloped in response to evolving customer needs and expectations, John Deere has launched its Performance Tiering Strategy, delivering a range of products at different levels of capability and user experience.

Available first on the wheel loader lineup, the Performance Tiering Strategy supports customers by providing machine solutions built for various applications and jobs to enhance profitability and efficiency. Moving away from the traditional series letter designations, the Performance Tiering Strategy provides three tiers of machines – G tier, P tier and X tier.

“Every job site is unique, and customers want machine solutions that can be personalized to meet their diverse needs, including performance, price and comfort,” said Jason Daly, global director, production systems, technology and marketing, John Deere. “By offering three tiers, customers can move up or down the spectrum to find the right mix of features, performance and innovation for their business and application.”

The Performance Tiers are defined as: X-tier models built with innovative John Deere technology and features, delivering high levels of productivity, efficiency and customer experience.

P-tier models include advanced features that deliver exceptional performance, efficiency, comfort and service life in demanding, high-production applications.

G-tier models are practically equipped and economical, providing proven capabilities with the reliability and ruggedness expected from John Deere. These machines are ideal for customers in need of a reliable machine to complete common light- to medium-duty tasks.

MACK TRUCKS INTRODUCES NEW PARTS STORE AND FUEL SAVINGS CALCULATOR

M

ack Trucks has made a series of additions to their website that aim to help customers easily find, order, and decide on parts.

The new PartsASIST platform provides a one-stop online solution that gives Mack truck owners a more efficient service and support option to help improve uptime. Knowing that fleets and dealers often identify trucks differently, whether by VIN or fleet unit number, the new PartsASIST platform connects fleet unit numbers to individual VINs, resulting in quicker and easier tracking and documentation.

Integration of Mack’s Genuine Parts and All Makes catalogs simplifies searching for model-specific components, while real-time data cross-referencing provides instant insight into inventory availability, helping to ensure that what customers see in the catalogs and purchase is what they will receive.

Registering for PartsASIST and transitioning from the current Mack SELECT Part Store will allow for quick parts selection from the Mack Trucks dealer network in the U.S. and Canada as dealers join the program throughout 2021.

In addition to the newly launched parts store, Mack Trucks has introduced a fuel savings calculator to clearly show fleet owners and owner-operators how much fuel savings could be realized if their trucks were spec’d with the next-generation Mack MP8HE+ powertrain package.

The fuel savings calculator allows Mack website visitors to select fleet size, number of trucks in their fleet and the average cost per gallon of diesel fuel. The information is used to calculate the average amount a customer could save over one, three or five years with the Mack MP8HE+ powertrain package.

The savings are in part attributed to the next-generation MP8HE engine which captures waste energy from the engine’s exhaust and converts it back to mechanical energy delivered to the engine crankshaft as additional torque. Mack engineers designed an updated wave piston to help evenly distribute the air-fuel mixture within the cylinder to burn fuel more completely and consistently than other piston designs.

RITCHIE BROS. OFFERS FREE ONLINE INVENTORY MANAGEMENT SYSTEM TO CUSTOMERS

N

o matter how many assets a company has, proper fleet management is necessary to keep track of usage, condition, deployment, remarketing. However, many companies are tracking this information through individual spreadsheets, which can lead to problems with document sharing and version control.

Ritchie Bros. Asset Solutions’ cloud-based inventory management system is designed to modernize asset management and disposition. With the free version of the inventory management system, users can upload their entire fleet with photos and detailed equipment info into a mobile-friendly dashboard.

Once their fleet is in the IMS, customers will be able to easily request inspections, appraisals, pricing data, and more. The entire organization will then be able to see the fleet, where assets are deployed, research equipment values, and more. Users can also send equipment to a Ritchie Bros. sales channel with the click of a button.

FPT INDUSTRIAL LEADS PROJECT FOR ALTERNATIVE FUEL FOR HEAVY-DUTY ENGINES

MORE NEWS

F

PT Industrial is developing a way to use DME (dimethyl-ether) as a fuel in order to help meet European carbon emission targets in 2025 and 2030.

Experimental data is showing promising results in terms of CO2 reduction, along with minimal emissions and similar engine efficiency to diesel.

Suitable for compression ignition engines and produced from several renewable sources, its chemical properties allow for very low particle emissions while still maintaining engine efficiency.

Since DME combustion produces almost no particle emissions, a simple SCR system without the need for a particle filter may be enough to comply with strict emission standards.

The overall goal of the project is to advance the understanding of using DME as an alternative to diesel in the industrial goods sector and to demonstrate clean combustion at comparable efficiency levels.

TADANO 80-4 ALL-TERRAIN CRANE

Tadano

Eighty-tonne all-terrain crane The Demag AC 80-4 is an 80-tonne crane that features a main boom that is 60 metres long. With some configurations it is possible to have the longest main boom reach in the class of up to 120 tonnes, Tadano states.

The AC 80-4 can lift 5.4 tonnes at a radius of 14 metres.

If the main boom length of 60 metres is not enough, the reach can be expanded with a 6.5-metre main boom extension that can be offset by 25 degrees and 50 degrees. Its capacity is 23.8 tonnes, meaning that it can be used to lift heavy loads over obstacles. Since the extension can be folded and carried on the main boom, it can be quickly ready for use.

On the full electric, lithium-ion battery powered compact rough terrain telehandler, the Snorkel SR5719E/SR626E, the open cab is also now available, in addition to a fully enclosed cab with heat.

The open cab version features the same spacious design and layout as the enclosed version, and includes an adjustable suspension seat and adjustable steering column as standard, delivering enhanced operator comfort. A mesh grid protects the operator while maintaining excellent visibility of the work area.

Liebherr VÖGELE S800I SCREED

Vögele

Small extending screed The new extending screed from Vögele, with a basic width of just 1.1 metres, is the smallest screed from the manufacturer.

Ideal for paving narrow paths, paving between tram rails or paving in milled tracks, the AB 200 extending screed has a basic width of 1.1 metres and extends hydraulically up to 2 metres.

This gives the new screed a basic width 10 cm narrower than the existing AB 220 and facilitates high-precision paving projects in extremely cramped conditions. Using a special system for pave width reduction, users can also implement pave widths of just 0.5 metres, as well as achieve a pave width of up to 3.2 metres using bolt-on extensions.

Brake Assistant and Incident Map features for wheel loaders Liebherr has developed two new assistance systems for wheel loaders: brake assistant and incident map.

Brake Assistant’s automatic speed reduction reduces stopping distance. Active personnel detection visually alerts the machine operator via the display screen and sounds acoustic signals if there is danger in the wheel loader’s rear area. The moment the active personnel detection system identifies a source of danger, the brake assistant slows the wheel loader down to a standstill.

Incident Map displays danger zones. Each time the assistance system detects a danger and a warning signal is issued, the system transmits a GPS signal to LiDAT, Liebherr’s in-house transfer and location system. On the basis of this signal, and for each operator of a wheel loader with active personnel detection, Liebherr provides a Google map in LiDAT showing these GPS points. The result is an incident map displaying the risk zones and potential sources of danger on the site.

SUSTAINABLE

POWER

IN-DEPTH REPORT

ELECTRIC EARTHMOVING EQUIPMENT

BY KAITLYN TILL, EDITOR IN CHIEF

JCB 19C-1E E-TECH MINI EXCAVATOR

IN-DEPTH REPORT: ELECTRIC EARTHMOVING EQUIPMENT

B

attery power has been one of the most exciting areas of development in construction equipment over the last several years, with multiple factors contributing to the growth in R&D and end-user interest. Advances in lithium-ion batteries; the need to reduce CO2 emissions in the construction industry; the demand for quiet, clean equipment for work in urban and sensitive areas; and the potential for increased utilization of electric-powered construction equipment are all factors driving this development. So in early 2021, where do we stand in the development of battery-powered earthmoving equipment?

APPROACHES TO BATTERY-POWERED CONSTRUCTION EQUIPMENT There is no one-size-fits-all approach to delivering low- or no-emissions equipment solutions for the construction industry, and there are several different OEM approaches to battery-powered equipment development for machines, which so far include compact excavators, compact wheel loaders, compact track loaders, backhoe loaders and now some mid-size machines.

JCB has had an engineering department devoted to developing electric construction equipment since long before the introduction of its first available fully autonomous electric mini excavator in 2019, according to Chris Lucas, excavator product manager for JCB. JCB introduced the E-TECH 19C-1E 1.9-tonne electric mini excavator to North America at the Rental Show in 2019, and the machine has since been updated to include a cab option.

Gathering operator feedback on machine performance and ease of operation will be critical in proving out the concept and ultimately the [E-Power] program’s direction.

According to Brian Hennings, product manager at John Deere Construction & Forestry, their approach to electric-powered equipment is similar to that of any other program at John Deere.

“It begins with gaining an understanding of customer needs, pain points and value drivers. Translating this input into solutions that unlock value for customers is essential to development direction and eventual sale of new products.”

John Deere’s approach to electric power, a program called E-Power, targets the operation and performance level of the company’s diesel-powered 100-hp 310L backhoe loader. With the E-Power prototype, Hennings said that the electric-powered model is designed to provide substantially lower daily operating costs, lower job site noise, enhanced machine reliability and zero tailpipe emissions.

CASE Construction Equipment unveiled the world’s first production-ready battery-powered backhoe loader at CONEXPO-CON/AGG 2020. The company partnered with Green Machine and Moog on the electrification and prior to launch had tested the 580 EV backhoe loader with utility companies on the east coast of the U.S. “The backhoe loader is perfectly suited for electrification as the varied use cycles, from heavy to light work, provide an excellent opportunity to convert wasted diesel engine hours into zero consumption battery time – yet provide the operator with instantaneous torque response when needed,” said Eric Zieser, director – global compact equipment product line for CASE Construction Equipment.

In addition to partnering with OEMs on electrification, Green Machine partners with manufacturers to sell some machines as Green Machine–branded equipment, including mini excavators in 1.7-, 2.6-, 3.5- and 4.5-tonne sizes. Green Machine directly sells, rents or leases this equipment and provides support for end users and dealerships to grow their battery-powered fleets.

In mid-2020, Bobcat announced that it has partnered with Green Machine on battery retrofits for its mini excavators, and the company is also working with Green Machine on the development of an electric compact track loader.

Brian Hennings Product Manager, John Deere Construction & Forestry

Volvo Construction Equipment now offers two electric compact machines – the ECR25 electric compact excavator and the L25 electric compact wheel loader. In 2019, Volvo CE announced that it would cease new R&D for its compact equipment powered by diesel engines and has committed to transitioning all new development in the compact segment to battery-powered machines.

Volvo CE’s ECR25 compact excavator and L25 compact wheel loader, which were unveiled at bauma 2019, are now on customers’ job sites, and according to Ray Gallant, vice president product management and productivity for Volvo Construction Equipment, those customers really like them.

“What they particularly focus on is the fact that it’s quiet, it’s clean and there’s no vibration, but the performance and the characteristics of the machine are exactly the same as a diesel [machine],” he said.

WHO WILL BENEFIT FROM ELECTRIC CONSTRUCTION EQUIPMENT?

While the cost of an electric machine is substantially more than the diesel counterpart, there are several benefits. While the most obvious advantage is the elimination of fuel consumption costs, electric machines are also typically easier to maintain and have lower maintenance costs.

These machines are also able to work in sensitive environments, such as near hospitals or indoors, due to their low noise levels and zero emissions. These advantages open up opportunities for contractors and rental houses to expand to scope of the work that their machines can do.

Utilities operations are a major market opportunity for electric equipment. CASE, John Deere and Green Machine have all worked with utility companies to test their equipment and that market is key. CASE’s first models of the 580 EV have gone to two utilities operations.

According to Hennings, utility providers and governmental entities see value in backhoes with zero tailpipe emissions. Other potential customers include those that value lower job site noise,

especially when working around sensitive populated areas or in enclosed buildings or tunnels.

The rental industry is also getting on board with electric compact equipment. Cooper Equipment Rentals was the first North American customer for JCB’s electric mini excavator.

According to Rod Lentino, rental fleet manager, one of the things that they liked about the JCB excavator is that it is approved for underground use and meets Canadian safety standards for underground applications. This has enabled Cooper Equipment Rentals to work with mining companies in northern Ontario where the JCB machine is used with breakers to recover ore from more delicate parts of older mines, such as pillars. The electric excavators are also ideal for carrying out minor cleanup of debris underground.

Cooper Equipment Rentals has also had its JCB excavators work in indoor applications, such as installing moving sidewalks at Vancouver International Airport, as well as interior and renovation work in B.C. and Ontario.

The technology is still in its early days and, like any technology, Gallant from Volvo CE expects that as supply chains develop and demand increases, the sticker price will come down. For now, the key is to identify the applications and customers that will derive the most benefit from an electric machine.

HOW DO ELECTRIC MACHINES STACK UP AGAINST THEIR DIESEL-POWERED COUNTERPARTS? While there are many obvious benefits to operating a battery-powered machine, the ultimate test is whether the machine can deliver the same performance as its diesel counterpart while providing a contractor or rental house with the ability to take on new jobs that may not be suited to diesel machines.

“What may surprise you, and it surprises a lot of people, is that the electric product actually delivers more torque, on immediate output, than the diesel variant. So as far as power and performance, there is no sacrifice,” said Lucas.

With a diesel machine, whenever the operator goes to dig, the engine has to gear down to get the horsepower to pull through, whereas an electric product has continuous power. The same voltage and the same power surges through the machine regardless of the task.

Referencing the CASE 580 EV, Zieser said, “At low idle a diesel engine has reduced torque and requires time for the engine to ramp up to meet the load demands. Electric motors, on the other hand, have instantaneous torque and peak torque available at every operating speed.”

According to Leandro Lecheta, head of CASE Construction Equipment North America, “The CASE 580 EV is equal in breakout force to diesel-powered backhoes in the CASE product line.

It provides lower daily operating costs while also producing zero emissions. This allows it to work in tight spaces and enclosed working conditions.”

Battery-powered machines cost roughly double their diesel counterparts, so factoring in the long-term savings when making a purchasing decision is key. Something else to factor in, if you work in enclosed environments, is the cost of renting exhaust extraction equipment. Other benefits include low noise levels, which may allow you to work after-hours in noise-sensitive environments.

Lucas had one customer who worked in highway construction, which he noted is not an industry that he had thought would be a target for electric products. This contractor was putting in culverts underneath a highway and to do one job cost over $3,500 in

rental fees for exhaust extraction equipment. Utilizing an electric machine eliminates that cost.

Technicians at JCB dealers go through high-voltage training, but on the whole, Lucas noted that electric machines need far less servicing than machines with diesel engines – another significant long-term cost savings.

What may surprise you, and it surprises a lot of people, is that the electric product actually delivers more torque, on immediate output, than the diesel variant. So as far as power and performance, there is no sacrifice.

Chris Lucas Excavator Product Manager, JCB According to Lucas, a study that compared the E-TECH mini excavator with the diesel equivalent machine found that over a three-year span the electric machine saved 48 percent on the cost of servicing. With a JCB electric machine a daily inspection involves walking around the machine to make sure that there are no tears in wires and that hydraulic levels are right, but there is otherwise no checking of oil, changing oil filters, or maintenance of a diesel engine. “From the operator’s perspective, it’s really quick and simple,” he said.

WHAT DO CONTRACTORS NEED TO KNOW ABOUT BATTERIES, CHARGING AND MAINTENANCE OF AN ELECTRIC MACHINE? As is the case with adopting any new technology, contractors are going to have a few concerns about battery-powered construction equipment.

According to Aaron Kleingartner, product and dealer marketing manager for Doosan Infracore North America, the customer typically has two questions about electric equipment. The first is how the performance of the electric machine compares with the diesel equivalent machine – does the machine provide the same, or better, breakout force and lifting capability, and are you able to use the electric machine in the same fashion as the diesel equivalent? The second concern is over how long the battery lasts – can the machine be used for a typical full work day?

Doosan is designing its first electric machine to address both of these concerns. Kleingartner noted that the second question is the harder one to answer. The machine can be designed to meet the criteria, but the run time is dependent on the environment that the machine will be used in. He added that the goal is what would be considered a traditional eight-hour workday. Doosan’s DX17Z-5 electric prototype has been designed to have two charging modes, a normal charging mode with a 110-volt input or a faster charge with a 220-volt input.

IN-DEPTH REPORT: ELECTRIC EARTHMOVING EQUIPMENT

JOHN DEERE E-POWER ELECTRIC BACKHOE PROTOTYPE

With a diesel machine, as long as it’s maintained and you’re putting fuel in it, it can run 24 hours per day. Like Kleingartner, Lucas noted that extending the run time is a key challenge. JCB’s 19C-1E can run for a typical full day’s work, but the challenge is making machines that can run for that full day regardless of application.

Lucas added that another challenge is having the right power source at the job site for recharging the machine – JCB offers three different options for charging its lithium-ion battery pack based on where you are and what power sources you have available. JCB’s power options for E-TECH equipment are: standard 110 volt, like you would find in your house; a 220-volt faster charge, but not everywhere is wired for that voltage; and 480volt fast-charge option. The fast charge is an external unit that requires specific wiring and can fully charge a machine in two hours. Charging at 110 volts takes ten hours and charging at 220 volts takes around eight hours.

DEVELOPING AND TESTING PROTOTYPES There has been a flurry of new development announcements over the last few years, and while the first electric earthmoving machines available or in development were mostly compact excavators, OEMs are branching out into other types of machines and larger size classes.

John Deere will be testing its E-Power backhoe loader prototype with National Grid, an electricity, natural gas and clean energy company that serves 20 million customers in the U.S. northeast. According to Hennings, the testing will be done on several job sites to gain a robust, representative composite of their machine tasks and applications in varying weather conditions.

National Grid uses backhoe loaders for the development, maintenance and repair of their underground delivered utilities. Daily tasks performed in testing the E-Power backhoe could include self-transport to job sites, trenching, digging around utilities,

22

heavyequipmentguide.ca | FEBRUARY 2021

truck loading, backfilling, site clean-up and more. Hennings noted, “Gathering operator feedback on machine performance and ease of operation will be critical in proving out the concept and ultimately the program’s direction.”

Bobcat is developing an electric compact track loader, which the company displayed at CONEXPO-CON/AGG in 2020. The concept machine include components from Moog and Green Machine and Bobcat says that a major innovation in the T76e is controllability of horsepower and performance through electronic mechanics instead of the traditional hydraulic and diesel system.

Doosan is testing the electric equivalent to its 1.7-tonne DX17Z-5 mini excavator. It is estimated to be available in North America in early 2023. Takeuchi and Hyundai (in partnership with Cummins) are also developing electric compact excavators, and Gehl demonstrated an electric skid-steer loader concept at CONEXPO-CON/AGG 2020.

Volvo CE has been providing insight into testing new propulsion technologies for years, including the development of the prototypes for its first electric compact excavator and electric compact wheel loader. Now the company has unveiled another prototype – an electric wheeled excavator with a unique feature that goes beyond its propulsion system. In addition to being electric, the mid-size EX03 features a video screen on the rear of the machine which delivers safety messaging to pedestrians and drivers.

In early 2021, Komatsu announced that it has partnered with Proterra to use Proterra’s high-performance battery systems for development of mid-size electric machines. A proof-of-concept electric excavator is expected to be completed in 2021, with commercial production expected to start between 2023 and 2024.

The Proterra battery system powering the electric excavator will feature high energy density and fast charging technology. According to Proterra, the packaging flexibility of its battery platform allows for optimal placement within a mid-size excavator and will replace the need for a normal counterweight.

If you look to what society is doing, the drive for sustainable power is becoming quite widespread.

Ray Gallant Vice President Product Management and Productivity, Volvo Construction Equipment

IS THE FUTURE ELECTRIC? While it’s still early days, the activity in development and introduction of electric-powered earthmoving equipment has come a long way in just a few years. As we move into a future where there are greater demands for emissions reduction, battery power is here to stay as a key part of the construction industry – and there are more alternative propulsion technologies in development.

At the launch of CASE’s 580 EV backhoe at CONEXPO-CON/ AGG 2020, Hubertus Mühlhäuser, CNH Industrial chief executive officer at that time, commented that the world of diesel, as we know it, will come to an end. Whether that happens 100 years from now, in 50 years, or in 20 years or less, diesel will eventually be replaced by different forms of propulsion.

Ziesler from CASE has noted that the 580 EV is just the start of the company’s approach to low- or no-emissions equipment.

“We’re proving the viability of electrification at the larger end of the compact and light equipment spectrum,” Zieser said. “Our goal now is to further expand electrification and alternative

DOOSAN DX17Z-5 ELECTRIC MINI EXCAVATOR PROTOTYPE

propulsion into other product lines and markets that will also see the benefits from these advances related to sustainability and performance.”

According to Gallant, Volvo CE is looking at more lines of its equipment that can be outfitted with battery technology, and he anticipates that other technologies, like hydrogen fuel cells, will come into play for some of the larger equipment.

Gallant also anticipates that laws will require that contractors make sure their construction equipment is clean and quiet for work in urban areas and populated areas. “If you look to what society is doing, the drive for sustainable power is becoming quite widespread.” HEG FEBRUARY 2021 | heavyequipmentguide.ca

AGGREGATES & QUARRIES

VOLUMETRIC MEASUREMENT OF MATERIAL MOVING ON A CONVEYOR IS MORE PRECISE AND ACCURATE THAN LOAD CELLS OR OTHER OPTIONS.

VOLUMETRIC SCANNING WITH OPTICAL BELT SCALES IMPROVES AGGREGATE OPERATION EFFICIENCY

BY LEE TOOP, EDITOR

M

easuring and managing the flow of aggregates has always been a challenge for quarry operators. Keeping track of how much product is moving from a crusher or screener is frequently difficult to do with precision – and causes a hit on the bottom line.

The use of conveyor weighing tools has become more popular, giving operators a better look at what’s being moved on any particular unit.

However, physical weighing of material moving across conveyors has its own potential problems.

A solution that is gaining in interest for aggregates operations is the use of laser technology to measure material using 3D imaging technology. An easy add-on to conveyor systems, optical belt scales provide a far more detailed look at the amount of material being moved while providing head office or remote personnel more data to fine-tune

24

budgets and improve profits.

Optical belt scales developed by manufacturers like H-Sensortechnik offer a range of benefits over traditional scale systems, especially in the busy environment of an active quarry. Traditional units rely on load cells that are placed on the conveyor; these often have issues with declining quality over time. In addition, load cells need to be recalibrated when conveyors are moved around – and with mobile machines growing in popularity, that means more time spent fiddling with calibration rather than producing material.

Optical belt scales, in comparison, require far less calibration and are more wellmatched to mobile equipment than load cells. These units are mounted above the belt and use lasers to volumetrically measure material moving beneath them, with no moving parts to be knocked out of calibration through vibration or conveyor movement. Wind,

heavyequipmentguide.ca | FEBRUARY 2021

dust, temperature and other factors have no effect on these types of tools, either, making them more efficient and more precise than load cells, according to H-Sensortechnik.

As material moves through the scanner, Sensortechnik tools detect the level of product by measuring the cross-profile of the material on the conveyor belt and the feed rate of the belt, providing data on the material flow in cubic metres or yards which can be converted to tonnage with the use of bulk density factors.

The Sensortechnik unit has a measurement accuracy of 1 mm variance and is precise on both stationary or tracked machines.

Volumetric measurements collected by the optical belt scale are transmitted to users in multiple ways. For immediate use, the data is sent wirelessly to the operator’s handheld device or computer; the operator can configure their scan settings as needed

OPTICAL BELT SCALE MEASUREMENTS ARE EASILY ACCESSED ON MOBILE DEVICES SO OPERATORS CAN TRACK EQUIPMENT PERFORMANCE.

including changing the material types or customer profile.

In the office, Sensortechnik optical belt scales interface with SensorTrack, a data management system that provides real-time visibility based on scale, site and material types,

LASER MEASUREMENT SYSTEMS CAN BE MOUNTED ON MOBILE EQUIPMENT WITHOUT THE NEED FOR CONSTANT CALIBRATION.

providing metrics and performance indicators at a glance.

Those measurements give managers a wealth of data that can be analyzed to determine a range of factors such as how much material is processed daily and any trends that are arising and causing problems with overall operations. Use of

this data allows operators to understand when operational issues are cropping up and respond quickly to save money and time from downtime or other factors.

“Through visualizations and an easy-to-navigate dashboard, SensorTrack provides owners and operators increased

visibility into their business in real-time,” said Charles Arnot, sales manager of Frontline Machinery, North America distributor for H-Sensortechnik.

“In many aggregate operations, producers rely on traditional material measuring tools such as loader scales and stockpile reporting which can be inaccurate, dated, and can result in inventory discrepancies.

Instead, the optical belt scale provides accurate and timely data ensuring producers never miss any critical information needed to take action.”

OBS systems can be easily integrated with operations that use programmable logic controllers (PLCs) or other in-house reporting tools, providing flow rate control and continuous monitoring. This connection is available both hardwired or can be configured via wireless networks. All information is available to be downloaded into internal data-

bases for data management.

With precise measurements being recorded by the optical belt scale, operators are able to track the flow and loading of material far more effectively.

For example, one operation loads aggregate barges via conveyor and has traditionally relied on a physical measurement of the loaded material to determine when the barge was filled. With an OBS, the system loads the barge to a precise measure and then stops, ensuring the customer gets precisely what was asked for.

“Beyond being a practical measurement application, Sensortechnik Optical Belt Scale is truly an operations management tool. From verifying equipment and crew productivity, to centrally monitoring multiple sites and equipment, the Optical Belt Scale saves time, reduces costs and improves overall site management,” said Arnot.

AUTONOMOUS TRUCKS TAKE STEP FORWARD IN AGGREGATE OPERATION

A

Norwegian stone quarry will be the focus of a new approach to remote operation as Steer AS brings its technology to a fleet of autonomous dump trucks.

Steer, which has previously developed remote control construction equipment for use in areas where health and safety issues have been a concern, such as clearing of artillery ranges or dangerous geography, will be developing a system that adds efficiency and

cost-effectiveness to the autonomous fleet.

“This is a milestone for Steer. With this contract, we are taking a giant step from our first contract in 2009 which involved clearing a large artillery range in the Norwegian mountains,” said Steer CEO Pål Ligård.

Steer will be developing a system in which autonomous trucks are loaded with stone, then follow a set route out of the quarry to a dump site leading down into a crushing plant. From

The Ultimate in Separation™ Our WALKER™ and JAVELIN™ brands of durable and powerful industrial magnets are capable capturing metal from mining, aggregate, scrap and recycling operations of any size and capacity.

there, the product will be shipped by boat to markets around the world.

The trucks’ movement will be repetitive, making the site an ideal location to develop autonomous operations even more, according to company officials.

The wheel loader operator loading stones onto the fleet of trucks will also be able to oversee and direct the trucks using an iPad from their seat in the cabin.

“At the start of the project, we will

place drivers in the remote-controlled trucks as a precaution to ensure that the technology is working correctly and meeting expectations,” said Steer co-founder Njål Arne Gjermundshaug.

Testing is currently underway in Oslo, Norway, using small trucks, Gjermundshaug noted.

“This is to test the technology so it’s meeting the expectations we have for precision, safety, usability and operation time.”

Q&A SMS EQUIPMENT’S RAY TREMBLAY TALKS PREPARATION FOR THE PAVING SEASON

BY LEE TOOP, EDITOR Asphalt paving season is coming soon, and it’s time for contractors to think about preparing their equipment to hit the job site. What are the best ways to prepare asphalt paving equipment for the busy season? Heavy Equipment Guide spoke with Ray Tremblay, SMS equipment manager, Road Construction Tech Support, about how paving companies can get the season off to a good start.

Lee Toop

What is the best way for contractors to think about getting ready for paving season? What should they keep in mind when they’re coming into that busy period?

Owners should do a proper inspection to get ready for the season, then do any needed repairs and other preparation so the machine is in good operating condition.

That way, they don’t have to touch it for the three or four months of the paving season.

If they have a really good inspection report and maintenance program; go through the sprockets, wear items and all of those points; clean and make sure everything is up to speed with the engine, final drives and other components, they should have a trouble-free season.

heavyequipmentguide.ca | FEBRUARY 2021

LT

RT

What are the key points that paving companies should look at when they’re prepping for the season?

Usually, it’s wear items. Especially with pavers, you need to look at your auger flights, your auger bearings, the supports, the screed plate, the screed, your floor plates and your slat chains.

Anything that moves material is your main concern. You want your auger motors, gearboxes, the drive chains, you want all that at 100 percent so you don’t have to do anything mid-season when you get into higher production. Say you’re on a high-production job, and all of a sudden you break down. Now, you need to get that paver out of there. You’ve created an interruption on your mat. Plus, you have trucks and the plant – everything’s all aligned.

LT

RT

What are the areas that the contractor should be looking at in their shop and what should they come to you guys for?

If they have a mechanical department then they’ll get training and their guys will go through it. When it gets to more modern machines with newer technology and electronics in the engines or machine software, then you’re more reliant on the OEM and the dealer. If it’s older equipment, they probably have lots of experience and knowledge in house. For a small paving company that can’t afford to hire a mechanic 100 percent, then they will reach out to the dealer. It all depends on how big a company they are, how many pieces of equipment they have, and so forth. If they have just one machine, they probably won’t have a mechanic unless it’s an owner-operator who does the work themselves.

LT What are the biggest issues that paving companies come to the dealer for in terms of pre-season preparation?

RT

LT

RT

It can be large repairs. If it’s a new machine, anything warrantable, they’ll use the dealer because that’s covered. . .if the company gets extended warranty or long-term, four years or five years, then they’ll utilize the dealer. That way they protect themselves if anything technical that goes wrong with final drives, the engine or hydraulics that are covered under special warranty.

There’s different types of warranty plans you can get.

Some customers feel they can look after themselves.

So, you just reach out. And what we do is, come the fall, our product support guys will ask if they want an inspection. And then we’ll provide recommendations on what’s worn and what should be repaired.

What areas do owners sometimes miss in their service that should be considered as they’re coming into the season?

I’ve seen where a customer will work late into October, November, maybe into December, depending where they’re at, and then the season will be over. They’ve had a hard season, they’ve beaten the weather, and then they’ll just park the machines and not do anything with them. They’ll wait until the spring, and then they’ll bring their crews in and try to go through the machines at that time.

What could happen is, if there were any problems that haven’t been documented or addressed at the end of the season, they could get missed. As they start paving, they have to go in and address the problems.

LT It’s important to consider that post-season wrap-up then?

RT

If they develop a program and a policy where they do everything post-season, it’s better because then the machine is parked. But it all depends on how good a season they had, what their finances are like. Maybe the owner has, every year, left it for the spring and that’s just how he operates.

If you do a good inspection, then they have the report for the spring, they can refer to it and go on that way – and it gives them time to bring parts in on a standard stock order. Some customers do a winter program where they will bring a machine in and work at that time, so it’s not a rush.

LT How much is telematics and emerging technologies around service changing and improving these pre-season maintenance plans?

RT

A lot of the bigger companies are utilizing it because that way they can manage where the machines are.

They also have operating hours, so they can see when a machine’s due for scheduled service and address that. They can manage their equipment a lot better; they’re not running double services or missing a service the whole season.

LT

So, you have the machine prepped and ready to go.

What should contractors and their operators be watching for to make sure they stay in good condition through the season?

RT

The biggest thing is training operators to understand the machine, understand the operation of the machine. A lot of customers, their people are seasonal, they stay with them. So, they have a good idea. But with new product lines, it’s always good to get training – there are always things that change.

And you always bring new people in. Over the winter, people can get complacent and then you have to start again. With the new season, you need to start thinking about the product and the application.

So, yeah, training in operation to understand the machine helps everyone get along and makes the job go a lot smoother. It’s better for the operators, for the supervisors, the owners, everybody – even for the machine, because the machine isn’t abused and it’s run more correctly. HEG

he KMA 240(i) cold recycling mixing plant produces mix/ cold mix that can be paved immediately and is ideally suited to producing different types of bound base layers. In addition to cement-treated base layers (CTB) and roller-compacted concrete (RCC), the machine can also be used to produce bituminous bound base layers (with emulsion or foamed bitumen).

The cold recycling mixing plant is mounted on a flatbed semi-trailer and has its own engine unit. This mobile design allows the system to be flexibly moved to different locations and set up rapidly. In its new cold recycling mixing plant, Wirtgen has combined the advantages of its earlier model, the KMA 220(i), with improved mixing performance and an innovative cement metering system with automatic self-calibration via static weighing.

The six-cylinder diesel engine is designed for the machine’s high mixing capacity of up to 240 tph.

Thanks to an efficiently insulated housing, it also emits very little noise. The engine can be operated for up to two days on one tankful. Its low emission values also allow it to be used in urban areas.

With a capacity of 240 tph, the machine produces a full truckload of 20 tons of mix every five minutes. As a result, sections of a cement-treated or bituminous bound base layer with a working width of 4 m and a paving thickness of 15 cm can be completed over a length of 1,400 m every day.

The KMA 240(i) has the ability to process a large variety of non-cohesive base materials, making it possible to produce mixes/cold mixes from a wide variety of new granular mixtures or various milled materials and binding agents.

Silos or tank trucks supply the cold recycling mixing plant with binding agents, such as hot bitumen, bitumen emulsion, and cement. Precise metering of the input materials and binding agents is monitored by a proven micropro-

TECHNOLOGY IMPROVEMENTS ON CONCRETE SCREEDS MEET TIGHT TOLERANCES

oncrete is an ubiquitous part of construction projects and often provides the base upon which many other aspects of construction rely upon for strength and support. Whether it’s a new road or the structure of a high-rise building, concrete slabs need to provide strength and, to work as a base for construction, it must also be poured with precision.

While concrete pads have previously been levelled with extensive help from surveyors, hand measurements and other tools, today’s concrete tools are leaning into the growth of measurement technology.

Laser measuring equipment tied in with total stations and other precision instruments are bringing greater quality to concrete construction.

In fact, laser screeds have been available for more than three decades, according to Andy Werdin, sales manager at screed manufacturer Ligchine.

The technology has steadily developed over the years since that introduction, with regular improvements that have constantly added precision to the concrete finishing process.

“Screeds have been around since the late 1980s. . .obviously it’s grown in leaps and bounds,” he said. “We’re using lighter, more robust materials, and machine programming has come a long way in that time. A lot of early machines had basic PLC controllers on

them – now they have microprocessors that will run with your computer. With the development of smarter systems, different laser technologies and positioning systems, that has all contributed in producing a better, tighter product.”

Myron Hillock, sales director with screed manufacturer Somero, noted that while the screed itself has changed little over time, the technology itself has changed greatly.

“I’ve been with the company since 1998, and when I came onboard they had just entered the second generation of the technology that controls elevation of the screed. The framework of the machine, the engine, the hydraulic propulsion. . .it’s very solid as construction equipment. Where the technology lies is in how we control the screed head,” Hillock said.

Precision measurement on job sites can be a challenge because of the surroundings and the situations in which screeds are being used, Hillock noted.

Something as simple as a stiff breeze can cause a challenge, Hillock noted.

“If a compactor or dozer happens to be working in the vicinity of the tripod, well, that vibration can be transmitted through the legs to the transmitter, and send out a shaky beam. Or, if the laser transmitter is mounted on a clamp and attached to a wall, if that wall is being buffeted by

winds on the outside, you can have inaccuracies,” he said.

“Then you have interior slabs – most every interior slab has columns supporting the roof, but the further you get away from the laser sending you the beam, each of those columns starts to cast a shadow.”

Somero screeds operate with laser receivers on mast poles at either side of the machine to allow for the system to make adjustments independently on either side as the pad is levelled. Those receivers can often fall into the shadow of a column and lose the beam – and precision. That’s where smarter technology helps out, Hillock said. “If one side goes blind, the other side automatically mirrors what the good side is doing – that’s our first default,” he explained. “Then, the minute it receives two signals again, they return to totally independent.”

In addition, Somero measures elevation in both vertical and horizontal directions. If the screed starts to twist and push off the contact point with the concrete due to buildup of material or other occurrence, the company’s Self Leveling Head technology recognizes that and makes adjustments to ensure there’s no interruption of the concrete mat.

Advancements in technology have focused on improved laser and machine control systems to ensure that the product is as smooth as possi-

ble, Werdin noted.

“The use of positioning systems and GPS have allowed screeds to perfectly match a plan for a parking lot. I think in meeting specifications, they are so much tighter now than they were 10 or 15 years ago – the use of machinery and technology is almost required to get the numbers that contractors need to be profitable and put out a product that is of quality to meet that specification,” he said.

For Ligchine that means partnerships with key technology manufacturers for products that use automatic machine control, telematics and other systems to ensure the high levels of performance that operators need. Wireless technology allows Ligchine machine operators to use their equipment remotely, allowing

MACHINES LIKE LIGCHINE’S SCREEDSAVER ELITE USE LASER MEASUREMENTS TO ENSURE A SMOOTH, PRECISE SLAB SURFACE.

LARGE SLABS CAN BE PAVED TO CLOSER TOLERANCES WITH SCREEDS LIKE SOMERO’S S-640 WORKING WITH TOTAL STATIONS.

them to observe the entire pour more closely, Werdin said.

In addition, screeds are also benefitting from increased awareness of remote diagnostics and monitoring that give owners a better understanding of how their machines are working and when they need maintenance or repairs. Somero’s equipment will tell an operator that a fault has occurred on the machine and saves it for later review, allowing the company’s service technicians to understand any issues that are recognized through the course of the day, Hillock said.

“Once, if you had an electrical issue, you’d be going through the entire machine to look for a loose wire or something.

Now it tells us exactly what’s wrong,” he said. “Same with the engine. . .as long as the engine is running, we are monitoring engine function, hydraulic and electrical functions all multiple times a second. If there are any glitches, the diagnostics will give us a code.”

Other technologies making inroads in concrete screed use include 3D control

systems, which allow contractors to input prepared designs into the computer and work with those plans to get the job done.

For example, telescopic machines equipped with 3D systems can handle tasks that would have been considered a challenge in years past. Hillock gave an example of paving over a ditch as a difficult task that is easier thanks to 3D controls.

“We can screed on a downhill slope of five percent or whatever it may be, transition through the valley at the bottom, and then that changes from positive slope to negative slope and we can screed the uphill face of that ditch,” he said. “Not only are we controlling the up and down,

we’re pitching and rolling the head to the desired location simultaneously as well.”

With contractors of all sizes taking more advantage of these high-technology additions to concrete screeds, there is a growing interest in the use of concrete construction where there might have been asphalt or other surfaces in the past, Werdin said.

“If contractors and business owners are looking at replacing an asphalt parking lot, they look at the maintenance costs and initial cost of asphalt versus the longevity and reliability of concrete, and that’s driving a switchover,” he said. “And the need for having tight tolerance slabs is always growing.” HEG

CONCRETE EQUIPMENT

UNIQUE TRACKED MIXER TARGETS OFF-ROAD CONSTRUCTION

A

unique tracked mixer has been developed by Prinoth and McNeilus to meet challenges of placing concrete in off-road projects.

An increased demand for off-road concrete identified by Prinoth dealer Multi Machine Inc. led to the partnership.

The dealer wanted to add a concrete mixer to its national rental fleet that would allow contractors access to hardto-reach locations, plus add opportunities for projects that would not be accessible to traditional mixers.

The main benefits of this collaboration are time and cost considerations. Concrete is a perishable product so

time is of the essence once you start mixing. A tracked mixer allows vehicles to quickly and easily move through soft soils or rugged terrain to get to job sites almost or entirely inaccessible by a standard vehicle, saving time. Access to these job sites can require a helicopter to move concrete in; this mixer makes that cost unnecessary.

When Multi Machine Inc. of New Jersey received the offroad concrete mixer request, they decided to come up with a solid, reliable solution that would last and also create additional opportunities. Engineering teams from Prinoth and McNeilus collaborated on

PRINOTH TURNED TO MCNEILUS FOR ITS CONCRETE MIXER EXPERIENCE TO DEVELOP THE OFF-ROAD TRACKED MIXER.

this unique project, adapting their equipment to suit the application and maximize mixer capacities while maintaining stability for an off-road application.

“When I heard about the project, I immediately knew we wanted to be involved. We work hard to provide solutions to our customer’s unique situations, and our team always rises to the challenge.

I knew this would be a unique project they would enjoy and would allow us to see our mixers more off-road than ever before. We’re now ready to build more of these unique vehicles to fill this need in our industry. McNeilus has a real focus on total cost of ownership, and this product can help provide an alternative solution for our customers,” said Bryan Datema, senior director of business development of concrete mixers for McNeilus.

To achieve the appropriate levels, Prinoth developed a special chassis while McNeilus developed a custom mixer body. The Prinoth Panther T16’s dropped frame chassis was a key design element to lower the overall height of the off-road rubber tracked mixer. By reducing the overall height, the centre of gravity is lower, which ensures great levels of stability and off-road performance. These modifica-

tions were necessary to allow moving the vehicle from one job site to another on a trailer without requiring special transportation permits.

McNeilus designed the mixer body for this special project to maximize payload and create an easy mounting process to the chassis. Specifically, special considerations were taken to customize hydraulic components and design routings to fit the new chassis.

The result is a heavy-duty 9-cubic-yard custom McNeilus mixer body that will stand up to the environment the vehicle will operate in.

When asked about the support they received, Multi Machine Service Manager Dan Waisempacher said “Prinoth’s application engineering team was able to use the technology and know-how from the product engineering team, to run tests, calculations and design a proper sub frame to position the mixer where we could be confident it would be safe, and still be able to handle the uneven and hilly terrain a Panther crawler carrier excels in. The team at Prinoth collaborated with the team at McNeilus and we worked together to figure out how many gallons of water and yards of concrete we could safely haul, taking into account the weight of the sub frame and water tank.”

EQUIPMENT MAINTENANCE

12 TIPS FOR EXTENDING EQUIPMENT TOTAL COST OF OWNERSHIP CASE CONSTRUCTION EQUIPMENT EXPERTS OFFER SUGGESTIONS FOR HOW TO GET THE MOST VALUE OUT OF MACHINES

BY LEE TOOP, EDITOR

It’s important to consider the total cost of ownership that comes with the purchase of any piece of equipment. There are many points to consider when it comes to TCO, however. CASE Construction Equipment experts have identified a dozen areas of equipment operation and management to consider, covering points that run the gamut from operating tips to maintenance planning.

REDUCING IDLE TIME While historically machines have spent a lot of time at idle as a normal practice, today’s machines are different and operators need to treat them differently.

“This is probably one of the most common topics you’ll hear referred to because of fuel cost and expense, which is certainly something everyone needs to consider, even with fuel prices as low as they are today,” advised Ted Polzer, CASE director of product and customer support.

“It has a lot to do with the emissions systems on these machines – today with new machine emission systems it’s critical to have higher exhaust gas temperatures to make those function properly.”

4

UNDERCARRIAGE AND TRACKS It's important to understand the condition of the undercarriage, tracks or tires on any particular machine, said Brad Stemper, North American light equipment product lead with CASE. “These components are pretty much the most costly wear item on a machine, so the more you do to be aware of their use and application, and to maintain their life expectancy, the more you’ll save over the life of that machine,” he said.

Stemper advised that a routine of daily walkarounds and pre-operation inspections is important to ensure the machine is clean and ready to run. Remove dirt and debris from the undercarriage or other moving parts to help keep the undercarriage clean and ready to go. heavyequipmentguide.ca | FEBRUARY 2021

5

UNDERSTANDING UTILIZATION It’s important to know how a machine is being used to ensure that it is operating to its full potential as well as receiving the necessary maintenance. There are multiple ways of doing this, including through the use of telematics such as CASE’s SiteWatch system.

“SiteWatch gives you the opportunity to dive in and really look at how that machine is being utilized, where it’s being utilized, when it will need maintenance and, maybe the biggest question, why that machine is being underutilized,” Polzer said.

ATTACHMENTS When a contractor buys a new machine they usually have a primary job in mind, but there’s a good opportunity to expand that use with a variety of attachments, Stemper said. Selecting a range of attachments means the machine can be used for more jobs on each particular site, and in some usages it might extend the time a machine can keep working. Landscapers, for example, generally use their machines mostly from spring through fall; a snow removal attachment can give them an extra few months of potential operation to expand the bottom line.

MAXIMIZING MACHINE OPERATION DURING USE Operating equipment at its peak potential is another strategy that is being supported by updated technology in modern machines, particularly through the use of operator modes, Polzer said.

“Wheel loaders offer different modes and excavators have different settings for throttle as well as pressure and speed,” he said. It’s key to read the operation manual and understand how these modes work; if that doesn’t clear up issues, then connecting with a dealer can be a good idea.

MACHINE CONTROL Precision pays, and machine control helps ensure that precision, noted Stemper. Use of a 2D or 3D blade control or excavation system is key to making a good operator better and improving efficiency through less passes and putting fewer hours onto a machine, while avoiding over-excavation or underdigging. Precision can also be improved by the use of things like payload systems, along with other options.

PLANNED MAINTENANCE INCREASES SERVICE INTERVALS AND IMPROVES UPTIME.

9

RENT, LEASE OR OWN? Ownership provides confidence and allows for operating optimization over time. Renting allows users to supplement their fleet for a specific need; while it’s a short-term cost it can be offset by the money the machine earns in that short time frame.

Leasing is a hybrid of the two – it lets owners get new machines more frequently and generally includes maintenance and support contracts to ensure the equipment stays working.

MACHINE FEATURES Selecting the right features on a new machine is key to good earning potential. Take auxiliary hydraulics, for example; Polzer pointed out that selecting high-flow hydraulics on a skid steer opens up more opportunity for jobs, and adding hydraulic options to run hammers or add thumbs on excavators is also a good consideration.

10

PROPER SIZING OF ATTACHMENTS Buying a bucket that’s too big for the machine is more common than one might think, and another area where advice from the dealer is a good starting point. Polzer explained that in some work conditions smaller buckets may keep things moving more efficiently.

“On an excavator we want to keep the arm and boom and bucket function moving all the time. . .a smaller bucket can actually help you be a lot more productive with the excavator by not overloading the machine and consistently keeping it moving,” he said.

PLANNED MAINTENANCE When purchasing a new machine, it’s a good idea to look into a planned maintenance contract, which adds assurance over the life of a machine that the proper work will be done at the proper time.

Programs like CASE’s ProCare offer a combination of factory warranty, telematics and planned maintenance to offer long-term assurance that machines will be ready to go when needed, and on machines that don’t fall into the program umbrella there are generally options for planned maintenance contracts available.

TELEMATICS AND MACHINE MONITORING ALLOW MANAGERS AND CASE EXPERTS TO CHECK IN ON MACHINE HEALTH.

REMANUFACTURING

On older machines outside their warranty period, remanufactured components are a good way to reduce parts costs, cutting costs in some cases by more than 40 percent over new parts, Polzer said.

“A lot of these components are the ones we’re using on our assembly line as well – the same makes and models. Any improvements that we make on our new machines, these are also benefits and features that we work with our remanufacturing team to include in their rebuilding process,” he noted.

EMISSIONS CONTROLS

New machines have a variety of emissions systems that are integral to their operation, and they can also be a challenge for owners to understand. If they aren’t maintained properly and their usage is misunderstood, they can bring their own costs.

CASE machines are designed to try and eliminate DPF (diesel particulate filters) in as many situations as possible to reduce the need for additional fuel burn and downtime; on lighter machines most have been designed without the need for DPFs or the use of selective catalytic reduction (SCR) or additional fluids, Stemper added.

DIESEL ENGINE DO’S AND DON’TS FOR A TROUBLE-FREE WINTER

BY JULIAN WOOD

T

he best solution to cold weather diesel starting problems in your vehicle is to avoid them by being prepared for cold weather before it happens. Diesel engines are harder to start in cold weather because they depend on high temperatures created by compression to ignite the injected fuel.

In fact, it is five times harder to start a diesel engine at 0° F (-17° C) than it is to start one at 80° F (26° C).

The top reasons for this are gelled fuel, cold cylinder walls and electrical failure. There are, of course, many others but addressing these three is a good place to start getting your diesel engine ready for winter weather conditions.

TIPS ON FUEL HANDLING FOR YOUR DIESEL ENGINE

• Do use winter blended diesel fuels which is less likely to gel.

• Do store full portable diesel fuel cans in a temperature-controlled area to avoid condensation.

• Do drain the water from the diesel engine fuel filter

• •

• •

•

•

daily, preferably when the machine is shut down for the day so the water does not sit in the filter overnight.

Don’t forget to drain the water separator on diesel fuel storage tanks every day.

Do fill the fuel tank at the end of the working day, as a full fuel tank doesn’t leave room for water to condense overnight.

Don’t neglect the diesel fuel filter – it’s the most common place for fuel to gel.

Do change the diesel fuel filter before winter weather sets in. That makes it less likely to freeze and avoids the need to do the job in the cold.

Do keep a spare diesel fuel filter and/or water separator on hand. It’s often easier to replace a frozen one than it is to thaw it.

Do park your diesel truck and equipment in a sheltered location whenever possible. A heated shelter is best, but simply parking your vehicle where the wind can’t blow snow and ice under the hood can make a big difference when you start the engine.

OTHER IMPORTANT FLUIDS BEYOND FUEL FOR DIESEL ENGINES TIPS ABOUT ENGINE OIL

• Do switch to a lighter weight engine oil in your vehicle during cold weather. A cold engine needs adequate lubrication especially when you start the engine.

• Don’t use engine oil lighter than the diesel engine manufacturer recommends as it may not provide adequate lubrication when the engine is hot.

COOLANT

• Do check your coolant regularly with a hydrometer.

The glycol in your coolant is there for a reason, it doesn’t boil off and it lowers the freezing temperature of the mixture.

• Don’t top off the coolant with some plain water.

Make sure to use a proper water/glycol mix every time.

You do not want water to freeze in your machine or truck engine or radiator.

• Do pay attention to vehicle temperature gauges and

avoid overcooling which can be caused by long periods of idling or excessive airflow.

Overcooling can cause poor combustion leading to white smoke, increased fuel consumption, and inefficient aftertreatment system performance.

DIESEL EXHAUST FLUID

• Don’t store diesel exhaust fluid (DEF) at below freezing temperatures. DEF is about 50 percent water and will freeze.

• Don’t worry about DEF in the tank on the machine; the system automatically circulates engine coolant to thaw it so it’s ready for use when the machine warms up to temperature.

COLD ENGINES

• Do inspect and, if necessary, check glow plug status and change them if needed.

Also review air inlet heaters before cold weather sets in.

It’s another job more easily done in warmer temperatures.

• Do consider using engine block heaters if one is

EQUIPMENT MAINTENANCE installed or installing an aftermarket unit. A warm engine is much easier to start and avoids many of the issues related to cold weather operation.

• Don't use starting fluid unless the machine or truck engine is equipped with a factory installed kit that precisely controls the amount used. Simply spraying starting fluid into the air cleaner carries a high risk of causing a fire or even an explosion.

ELECTRICAL SYSTEMS

• Don’t ignore your battery. After a hot summer that encourages corrosion and fluid evaporation the added strain of a cold weather start can kill a battery.

A battery can lose 35 percent of its power at 32° F (0° C) and as much as 60 percent at 0° F (-18° C).

• Do consider using a battery warmer, either a “hot plate” type that slides under the battery or an “electric blanket” type

that wraps around the battery will help the battery retain its charge.

SOME OTHER CONSIDERATIONS

Parasitic loads Parasitic loads can include: engine and transmission oil viscosity, fan drive, clutch engagement, hydraulic pump engagement, belt drive systems and anything else that’s driven by the engine or consumes some engine power. Any parasitic load during cranking can be a major contributor to the engine’s inability to start.

Warm-up time Always let a cold machine or truck engine warm up for at least five minutes before putting it to work. That gives the coolant, engine oil, hydraulic oil and DEF time to come up to operating temperature so they can function efficiently.

BENEFITS FROM TESTING IN COLD WEATHER ENVIRONMENTS

Diesel engine builders know their products will be used in virtually every environmental condition found on Earth and they go to great lengths to test them under extreme conditions.

Perkins, for example, has completed billions of hours of engine tests across different environments including cold testing at a Perkins facility in Arjeplog, Sweden, 100 km from the Arctic Circle where air temperatures drop to -49° F (-45° C).

A modern diesel truck or piece of equipment will start and run under all extreme conditions with very few things going wrong, but ignoring those challenges in your vehicles can be expensive.

Proactive preventive action may seem like an extra expense or time spent on something that isn’t a problem, now, but it makes economic sense in the long run.

The consequences of ignoring winter diesel fuel problems in your equipment or truck can range from losing all or part of a day’s work to repairing expensive engine damage.

Simple steps like keeping your fuel tanks and cans filled, plugging in heaters, using weather-appropriate fuels, strategic equipment parking and regular battery care can all make a big difference in how winter impacts your business.

LIFT & ACCESS

THE RISE OF LOW-LEVEL ACCESS LIFTS A SAFER, MORE PRODUCTIVE SOLUTION COMPARED TO LADDERS AND SCAFFOLDING

BY CHAD KRITZMAN

T

he history of human innovation for working at height dates back centuries. Scaffolding – first depicted in drawings from ancient Greece in the 5th century BC – was fashioned from wood secured by rope knots. Then, in 1862, American carpenter John H. Basely invented the first patented folding wooden stepladder. While designs have evolved over the years, both scaffolding and ladders continue to be hazardous for workers.

DANGERS OF WORKING AT HEIGHT

According to a CDC report, 20 percent of workplace injuries from falls involve a ladder. That statistic surges to 81 percent in the construction industry. In addition, more than 90,000 people receive emergency room treatment for ladder-related injuries each year. Falls-from-height violations ranked three separate times in OSHA’s Top 10 List of Violations for 2019. Fall protection ranked first with 7,014 citations, scaffolding was third with 3,228 and ladders sixth with 2,766 citations.

COST OF OCCUPATIONAL INJURIES

According to the 2019 Liberty Mutual Safety Index, serious, non-fatal injuries cost $189.81 million each week in the construction industry. The number one cause was a fall to a lower level – accounting for 25.29 percent of construction injuries and totaling $2.5 billion in compensation.

Unfortunately, hundreds of fatal falls occur each year. The National Safety Council estimates a fatal injury at work costs companies over $1 million per fatality.

LOW-LEVEL ACCESS LIFTS – A SAFER SOLUTION

Low-level access lifts offer a safer, more productive alternative to ladders and scaffolding that deliver a maximum work height of 20 feet. OSHA safety guidelines state that three-point (two hands and a foot, or two feet and a hand) contact must be maintained on a ladder when climbing. Low-level access lifts allow operators to use both hands allow for a 360-degree range of motion.

ERGONOMICS, VERSATILITY AND NIMBLE SIZE BOOST PRODUCTIVITY

The ability to carry additional equipment on the platform means fewer trips up and down ladders, which can significantly reduce fatigue – in addition to reducing the possibility of trips or falls. It also enables an ergonomic work position that reduces strain on the body and helps lower musculoskeletal injury risk.

Versatile low-level access lifts can replace multiple ladders, and these lifts are easier to move through doorways or from one

job to the next. With fewer components, low-level access lifts are a cleaner, quieter solution that are less disruptive to sensitive environments, such as schools and hospitals.

These lifts can eliminate the time it takes to assemble scaffolding, and compact footprints make them easier to store.

A SOLUTION FOR EVERY JOB

There are several types of low-level access lifts to support a wide range of industries and applications.

Personal portable lifts can be easily rolled through a facility and assembled or disassembled quickly, allowing workers to access catwalks, landings and other hard-to-reach areas. These lifts are ideal for applications including mechanical and electrical work, HVAC and ductwork, hanging drywall, painting, retail refit and display, construction finishing work and cleaning.

Non-powered vertical low-level access lifts like the JLG EcoLift Series can be used for many of the same applications as personal portable lifts. However, since the EcoLift is an eco-friendly solution with no batteries, hydraulics or oil, it is a completely leak-free machine, making its various models ideal for performing facility maintenance in buildings, including schools, hospitals and data centres. They are also quieter since they can be pushed into place and lifted/lowered with the turn of a handle.

Powered vertical low-level access lifts combine height and reach with low ground bearing pressure, making them optimal for use on sensitive floors and when the need to move them between floors using elevators is required. Where power is required, these lifts help boost productivity during finishing work or routine maintenance in indoor spaces.

REGULATIONS DRIVE NEED FOR SAFER SOLUTIONS As OSHA, ANSI and other regulatory groups continue to implement stricter regulations to enhance worker safety, there will be a greater need for safer solutions.

With their ability to provide greater safety to workers and help mitigate the costs of occupational injuries, low-level access lifts will continue gaining popularity on the job site. Available in a variety of configurations, low-level access products offer contractors an alternative to ladders and scaffolding to help minimize slips, trips and falls associated with more traditional methods of working at height.

EQUIPMENT ROUNDUP

DOWEL PIN DRILLING ATTACHMENTS DELIVER PRODUCTIVITY AND SAFETY

BY KAITLYN TILL, EDITOR IN CHIEF

C

ompact machines are for more than just moving dirt.

Today’s machines can be outfitted with specialty attachments that enable them to do more jobs and do them more efficiently – and safer – than ever before. Dowel pin drilling attachments for compact equipment can deliver significant productivity and safety benefits for concrete road repair jobs. I spoke with Rob Minnich president/chief marketing officer and Todd Jurjevic president/chief sales officer from Minnich Manufacturing to get the scoop on dowel pin drilling attachments for compact carriers – here’s what you need to know.

WHAT IS A DOWEL PIN DRILLING ATTACHMENT? A dowel pin drilling attachment can be used instead of hand drilling to insert steel dowel pins into the sides of the old concrete for a full-depth concrete road repair job. A dowel pin drilling attachment mounts onto the front of a carrier, such as an excavator, backhoe loader or skid-steer loader, and will not only drill straight, but has multiple drills that can work simultaneously.

A DOWEL PIN DRILLING ATTACHMENT DELIVERS TIME SAVINGS Hand drilling for one dowel pin takes anywhere from two to five minutes. With a dowel pin drilling attachment, the operator can complete drilling for multiple pins simultaneously, depending on the attachment model, all in under 30 seconds.

A contractor performing a series of patch jobs will typically set up a caravan of equipment to cut out material, pull it out, drill the holes, etc. The carrier machine with the dowel pin drilling attachment mounted on the front can easily move within this caravan.

SIGNIFICANT SAFETY BENEFITS Manual dowel pin drilling is hard labour and challenging to do accurately. The force going into the concrete is also going into the worker’s body – putting the drill on a machine saves wear and tear on the body. And, when outfitted with the optional dust collection system, these drills reduce debris on the job site.

MINNICH A-3SS

WHAT DO YOU NEED TO OPERATE A DOWEL PIN DRILLING ATTACHMENT? In addition to the carrier, the attachment runs pneumatically and requires an air compressor, which will typically be mounted on the back end of an excavator, sit in the bucket of a backhoe or be pulled behind a skid steer. Minnich Manufacturing works with contractors to provide the correct mounting harness to connect the attachment to their carrier and ensure that the attachment choice is right-sized to the carrier and compressor. Operating the attachment requires two people: one operating the attachment on the ground, and the other in the cab of the carrier.

THE MINNICH CONCRETE DOWEL PIN DRILLING ATTACHMENT LINE The line runs from A-2 through A-6; the most common model is the A-3SS (A indicating air-compressor-powered, the number indicating how many drills are on the attachment, and SS indicating that it has side-shift capability). Side shift capability is mostly commonly added to A-2 and A-3 models, but A-4 and A-5 can have side shift capability as well. The A-3SS can drill three holes at once, then side shift to drill three more without repositioning. HEG FEBRUARY 2021 | heavyequipmentguide.ca

Steelwrist Couplers Steelwrist is offering two new coupler solutions for excavators under two tons: the fully casted TCX S30-180 and S30 products. Both types can be delivered with manual locking or hydraulic locking, depending on customer needs. Both the TCX and S30 quick coupler come with a Front Pin Safety Hook. The tilt coupler provides a safe quick coupler solution and a tilt function that makes the excavator far more versatile. Installation is easy and the compact TCX has a low weight. It is available as direct-mounted with S30 coupler, both manual and hydraulic.

Prinoth Mulcher The M450e-1090 mulching attachment suits excavators from 8 to 15 tons, as well as other carrier vehicles with booms, up to maximum 90 hp. The power requirement of this mulcher is reduced by two-stage counter cutting at the material inlet, which prevents the rotor from being blocked if large pieces of wood are drawn in. Thanks to the gear motors used in this model, no leakage oil line is required – it can be attached to any excavator boom without additional conversion measures.

Minnich Manufacturing Dowel pin drilling attachments

The TC36 and TC48 are trencher attachments for lighter-duty tasks. The TC-series trenchers are designed for lower duty cycle customers in agricultural and light construction applications with configurations to match most soil conditions or trench requirements. These trenchers come equipped with a spring-loaded trencher boom that reduces system shock. The carefully designed frame provides easy ingress and egress during use. The crumber boom pulls loose soil into the trenchers, leaving a clean bottom, and an auger removes spoils from trenches, increasing productivity on the job.

A3 through A6 machine-mounted drills maximize productivity and safety on patchwork jobs. Featuring up to six drills, these pneumatically powered units can be mounted to an excavator, backhoe or skid-steer loader for full-depth repair. Available side-shift functionality enables operators to drill a second set of holes without having to reposition the carrier. An optional dust collection system is available.

LAST WORD

LAST WORD FIVE PREDICTIONS FOR AN UNPREDICTABLE 2021

BY PAUL WILSON

W

hat’s in store for the construction industry? How will OEMs and rental companies adapt to better serve their customers? How are customer needs changing? And, in the face of a global pandemic, what does recovery look like? The even bigger question: who will emerge stronger and how will they do it?

No one predicted the onset of COVID-19 and the degree to which the pandemic would impact the industry. But in many ways, it catapulted us forward. Here’s what we predict for 2021:

TOUCHLESS SERVICES WILL DRAMATICALLY INCREASE

The need to adapt and stay connected will be more readily accepted and expected. The COVID environment may persist well into 2022 and the demand for touchless functionality and associated solutions will become more widespread. More data will flow as a result of expanded services including: remote diagnostics, remote control, automated monitoring, enhanced predictive and remote maintenance, and more intuitive and context-driven user interfaces.

Businesses that have already invested in remote connectivity enabled by telematics will emerge from the pandemic even stronger. Those who haven’t invested are going to need to catch up in 2021 and be ready for a different operating future.

OEMS WILL SHIFT FROM SELLING TECHNOLOGY TO UNLOCKING AND PROVIDING VALUABLE SERVICES

Many OEMs understand the importance of technology that translates to the addition of valuable services for the life of the equipment. Some OEMs are starting to recognize that there’s a gap in the technology space that they need to fill. They’ll move beyond the technology sale to capitalize on the greater opportunity for long-term revenue. By leveraging telematics and the power of connection, they’ll provide improved machine design, greater safety, new services and expanded customer support that they couldn’t previously offer.

DATA BROKERAGE, PARTNERSHIPS AND APIS WILL RULE

Businesses that embrace the power of data sharing will achieve greater maturity in their digital evolution – knowing that by doing so, everyone wins. There is a growing need for simplicity, which is possible only if implementation and integration are unlocked.

Increased access to rich data insights is inevitable, and the complexity will demand a simple approach. It will be necessary for businesses to act pragmatically to serve their customers. When the industry works together, effectively combining their individual OEM, rental and general contractor strengths into a collective

purpose, data sharing becomes a key model of what it means to operate stronger together.

SUSTAINABILITY WILL BECOME A CRUCIAL TREND

As we continue to use up more the world’s resources, recognizing our own inefficiencies and identifying ways we can operate with greater efficacy will become a central focus and tenet upon which many companies will operate. Businesses need to embrace a global perception versus a regional one, and they need to create sustainable products that in turn will generate revenue with sustainable services.

Data insights enable proactive equipment maintenance, fleet health monitoring and smarter machine designs. Companies will be looking to leverage telematics to reduce machine idling, better allocate resources, manage transport and service logistics and measure in-field performance data to meet elevated standards.

ONLY THE STRONG WILL SURVIVE

Established companies are moving up the digital maturity curve and face the threat of disruption from innovations offered by smaller technology companies and startups. Mature companies will need to have a team devoted to the new and innovative to stay relevant. Successful businesses will elevate the adoption of their digital strategy and re-evaluate their future technology requirements and the need for a strong provider/partner. Choosing a trusted and capable telematics partner – one that demonstrates both expertise and vision will be crucial.

WHAT IT ALL MEANS

Technology users in construction environments will see it is no longer enough to focus solely on the basics (run hours and location). Enhanced machine data and machine control is driving the future of the industrial IoT. The telematics industry is going beyond simple monitoring and moving faster toward configuration and control, not only to understand what’s happening, but to control it, predict it and serve customers with remote or hands-off protocols. Those who emerge stronger, will do so by recognizing that the importance of technology isn’t just about a tangible product or device, it’s what you do with it that sets you apart.
