project. Technology has come a long way, propelled by demand for solutions to the problems we as a society face. Construction has certainly seen its share of problems the past couple years, with a plethora of technologies emerging to try to solve them. Of course, the technology developments started well before the pandemic. But the challenges of COVID-19 accelerated both its entrance into the industry and its adoption. While pandemic concerns eased on jobsites in 2021 (at least to a point), other challenges became increasingly prominent. We’re all well aware of the global supply chain disruptions that emerged early in the year and steadily worsened. Bottlenecks piled on top of bottlenecks have held up equipment and materials needed to complete projects, driving costs skyward and even causing some jobs to be delayed or cancelled. The source of the problem isn’t simply the inability of suppliers to ramp up production quickly enough to meet demand. It’s also the same problem this industry faces: lack of people. Worker shortages at ports, lack of drivers, insufficient workers to staff warehouses, etc., have made it difficult to get equipment and materials when and where they’re needed. Likewise, workforce shortages in construction have compounded the challenge of ensuring on-time, on-budget project delivery. And unfortunately, the struggle to fill positions is expected to worsen in 2022 given expectations of more construction activity with the infrastructure bill. Can technology solve the problems this time? Well, there are those who believe it can at least help. For example, technology such as grade control can enable inexperienced equipment operators to be trained more easily and become productive faster. And it can allow skilled operators to be even more efficient, meaning more gets done with the same machines and staff. So, while tech can’t offset the demand for workers, it could offer opportunities for companies to better utilize those they have by allowing them to get more done using the same equipment or by focusing more on project-critical tasks. Technology is, after all, a tool. And as Tyler Parker, business optimization manager, Black & Veatch, noted in a recent podcast (www.ForConstructionPros. com/21965055), “It’s a bit of a misconception that you can replace a human being with a tool... you need people to make these tools function well and provide value. Our focus is on training and educating our professionals on how to best utilize these tools and then let them tell us how... to really add value with them.” The goal? “We want to maximize the potential of everyone on a jobsite,” he said, “so that we can do more work with the trained professionals that we have.” ET

nderstanding how to use load capacity charts is crucial for proper selection and safe application of a number of machine types, but perhaps none more so than telescopic handlers. These versatile units are used to transport, lift and place materials and tools of varying weights, shapes and sizes using a selection of different attachments, often while operating on or over uneven or rough terrain. “Since telehandlers also have the unique potential to extend those materials away from the vehicle with the telescoping boom, it is up to the operator of the machine to assure the material it’s lifting, placing or carrying is within the rated capacity of the unit,” says John Boehme, senior product manager, JLG Industries. Each telehandler comes equipped with a load chart that outlines the different attachments it can support, as well as the machine’s operating range and operating envelope. But what goes into developing the charts and why is adhering to the recommended parameters so critical to proper, and safe, operation?
WHAT LOAD CHARTS ARE BASED ON AND HOW THEY’RE APPLIED “Load charts for all roughterrain telescopic forklifts used in North America are created per the ANSI/ITSDT B56.6 Standard. This design standard provides a consistent load chart development process for the industry,” notes Steve Kiskunas, product manager - telescopic handlers, Manitou Group. “Specific engineering tests are conducted with each machine to determine the correct capacity for the machines in various positions. Load charts indicate the maximum capacity of

the machine at various lifting ranges.” The three main aspects of operation taken into account within load charts are the overall weight of the load, the height and distance at which the load needs to be placed or picked up and the load capabilities of the machine. “The load capacity chart highlights two key elements: a telehandler’s operating range and its operating envelope,” says Boehme. “The operating range of the telehandler reflects minimum and maximum boom angles, as well as fully retracted and extended boom positions.” Attachments are also taken into account, with the operating envelope located relative to the load center position of the attachment being used, says Boehme. “The most common load chart will be for the standard factory-supplied forks with the load positioned no more than 24 in. from the carriage backplate,” says Brian Hatch, AMS-Merlo territory manager and tech trainer. “However, attachments other than forks can possibly have a load center greater than 24 in. from the backplate.” He adds that load charts for forks, grapples, jibs, buckets, etc., are permanently mounted on all Merlo models. Other manufacturers have also chosen to provide separate charts to match approved attachments. “Each Skyjack telehandler has its own capacity charts for the various carriages, forks and attachments that can be used with each machine to ensure safe operation,” says Rafael Bazzarella, product manager. “These options allow operators to use the machines in various types of applications, making the telehandler a very versatile and productive machine.” Additional criteria go into the development of load charts, as well. “As a manufacturer, when we create load charts, we have to factor in the weight of attachments and forks, load center of the loads, stability of the machine in all directions, stresses generated in all components, maximum forces in hydraulic cylinders and potential dynamic and wind loads exerted on the machine,” says Jeff Eckhardt P.E., vice president, chief engineer, Xtreme Mfg. “We generate
L IF T EQU IPMENT
load charts based upon the stability criteria in ANSI B56.6, as well as the stresses and loads in all the components used in the equipment. “The loading zones we subsequently supply to our customers on these load charts can be easily translated into what capabilities a particular project will need in terms of height, reach and load,” he adds. Load charts provide the guidance required to select the right telehandler for the task. “For general use, customers often first determine the maximum weight of the materials they will be using on a project,” says Kiskunas. “Then, they check that weight vs. the approved working ranges for that weight range on the machine load chart.
If the customers’ maximum material weight is equal or below the load chart weight for the areas they need to reach with the materials, that machine should do the required work.”
FOLLOW THE CHARTS TO MINIMIZE MISHAPS Load charts are also used to maximize the chances of safe, successful load placement. “That is essentially the function of the load chart — to provide the operator with the information regarding a machine’s operating range and envelope for the various carriages and attachments available for the specific unit they are using,” says Bazzarella. “By working within the load chart, the operator ensures the safe operation of the telehandler
Manitou’s MRT 2260 has a preloaded attachment load chart database that helps ensure the correct load chart is applied when an attachment connects to the machine.
If the maximum material weight is equal to or below the load chart weight for the areas the operator needs to reach with the materials, that particular telehandler should be capable of successfully completing the lift.
and protects the equipment from damage due to overloading.” “Understanding load charts and especially load centers of a particular lift project is one of the most important aspects of operating a telehandler safely,” Eckhardt emphasizes. “Operation of a telehandler beyond the scope of the load chart can and will directly affect safety of the operator and nearby personnel or property, safety of the load — which could have considerable value itself — as well as can shorten the life of a machine by causing early structural failures, component and hydraulic overloads and even dropped loads.” Using the wrong load chart can also have negative repercussions. “If you are using the wrong load chart with the wrong attachment, it could cause the machine to go into anti-overturn protection mode, prematurely slowing down jobsite progress,” says Hatch. “Wind speed and fork load center are also important.” Merlo offers an anti-overturn protection system that provides a safety factor to keep the machine from overturning even if the operator makes a mistake in applying an attachment load chart reference. “The length sensor, angle sensor and weight sensor provide the machine’s computer with a constant equation that calculates the safety factor and capability of the machine,” Hatch explains. Lack of or incorrect calculation of the load center of the material to be lifted can also hinder machine efficiency. “The load center can greatly affect the capacity of a machine,” says Eckhardt, “and often complaints of lack of ability to properly lift a load are actually a result of grossly underestimated load centers or complete lack of attention and understanding of the load center at all.” Misjudging the center of gravity, particularly for larger loads, and mispositioning the load on the forks is a common mistake, Bazzarella agrees. “Another mistake would be using the higher of two capacity values when there are intersections in the capacity regions,” he adds. Training on how to properly read and apply load charts is essential to avoid these and other common misapplications. “It’s extremely important to train

telehandler operators on the proper use of load charts,” says Bazzarella. “Understanding the importance and working within the load chart limits for the various approved carriages and attachments helps prevent accidents and abuse of equipment.”
SET YOURSELF UP FOR PROPER LIFTING Before using a telehandler for
a particular lift, it’s important to identify: ˜ the weight of the load and its center of gravity to ensure that it is correctly positioned on the forks; ˜ the height it will need to reach; ˜ the forward reach required; ˜ and the model’s load capabilities. Once equipped with this information, the load chart offers guidance that will allow the operator to confidently utilize the machine. “For example, once you have successfully paired the weight and telehandler model, you can use the load chart to assess the load placement or retrieval position,” says Boehme. “Because boom angles and extensions are an integral part of every load capacity chart, you will use boom angle and extension information to place or retrieve the intended load at the required height and reach.” “With this information, the operator can reference the load chart to determine the maximum boom angle and extension

allowed and then determine if it’s safe to continue with the lift or if the machine will require repositioning for safe operation,” Bazzarella adds. It’s important to ensure load charts are available on the machine for all attachments the operator may use, and that the proper chart is applied as attachments are changed out. “Operators must be sure that the load chart that they are using is correct not just for the machine, but also for the machine with that attachment,” says Kiskunas. To make this easier, Manitou’s MRT 2260 has a preloaded attachment load chart database that helps ensure the correct load chart is applied when an attachment connects to the machine. Merlo offers a built-in/onboard weighing screen on its telehandlers that “eliminates all the calculations and guesswork of the load charts for the operator,” says Hatch. “This screen will give you three readouts that help the operator stay informed of what the machine
is capable of and what is currently being lifted,” he notes. Readouts include the current weight on the forks/attachments; the maximum capacity of the machine at that particular moment in time; and the maximum capacity of the machine. Yet, even when such technology is available, it’s still important that telehandler operators know the basics. “Training helps operators understand the basic assumptions used to develop the load charts. The load is centered in a 4’ x 4’ x 4’ homogenous cube — a 24-in. load center or the center of 48-in.-long forks,” says Kiskunas. “Loads which do not have this load center, or loads that are unbalanced, can result in load and/or machine instability.” It’s also good to have a plan in place. “A proper plan for a lift is essential as one needs to understand the load weight, size of load and the specific worksite dimension,” says Eckhardt, “including any obstacles that may be encountered when performing the lift.” ET

High power density requirements and long run times make hydrogen an attractive source to eliminate carbon production.
T
he drive toward zero emissions is a complex undertaking for the heavyduty truck and large earthmoving machine markets. It will require innovative product solutions backed by a stable infrastructure that is cost comparative to running existing diesel-powered machines. During an April 29, 2021, press conference on driving a hydrogen future, Martin Daum, CEO, Daimler Truck, and Martin Lundstedt, CEO, Volvo Group, shared their visions of the future. “The road to zero emissions is like a multiplication problem,” Daum stated. “We need an attractive vehicle offering, we need a working infrastructure and we need cost parity. Those three factors are combined like multiplication. You know from high school in multiplication if one factor is zero, it doesn’t matter how big or how large the other factors are, the product is always zero.” All three factors need to be present in order for the solution to work. Meeting regulatory requirements and fleet goals to de-carbonize large construction equipment and heavy Class 7 and 8 trucks is going to require customized solutions. While there has been a lot of progress on battery electric vehicle (BEV) technology in compact construction machinery and light automotive applications, the power densities required by large earthmoving machinery and Class 7 and 8 trucks coupled with long work shifts may favor other solutions. If the goal is to simply reduce greenhouse gas emissions,
renewable fuels can provide a cost-effective option. According to Alastair Hayfield, Interact Analysis, carbon neutral fuels such as biodiesel are a good choice because they’re achievable and don’t require a big investment. “They are definitely an option because, practically, it is going to be very difficult to electrify everything. There are certain applications where it makes no sense from a cost perspective or an operational perspective,” he points out.
HYDROGEN DEBATE RESURFACES Lately, hydrogen has reentered the discussion as a promising solution for heavy earthmoving and other applications that require extreme power densities over long periods of time. In July 2020, JCB announced it had developed a hydrogenpowered excavator. The 20-tonne 220X excavator prototype is powered by a hydrogen fuel cell and has been undergoing testing at the company’s quarry proving grounds. “JCB will continue to develop and refine this technology with advanced testing of our prototype machine, and we will continue to be at the forefront of technologies designed to build a zero-carbon future,” says Lord Bamford, JCB Chairman. In March 2021, SANY shared that two hydrogen fuel cell-powered vehicles had rolled off its production line: a dump truck and a mixer truck. The company asserts that heat and water vapor are the only emissions from these hydrogen-powered vehicles. In addition, SANY says these new vehicles provide increased power due to the high-power fuel cell

Longer driving distances are possible, as well, using hydrogen cylinders with a combined capacity of 443.8 gal.(1,680 L), which ensures a driving range of over 310.7 mi. (500 km). Hyundai Construction Equipment recently decided to join forces with Hyundai Motor Group to develop hydrogenpowered construction machinery. Hyundai Motors and Hyundai Mobis will design and manufacture hydrogen fuel cell systems, including power packs,
while Hyundai Construction Equipment will design, manufacture and evaluate the performance of excavators and forklifts. The target date for mass production and distribution has been set to 2023. Unlike conventional diesel engine-based equipment, hydrogen fuel cell-based electric construction equipment uses electricity produced through the chemical reactions between hydrogen and oxygen as its power source, meaning no emission of toxic gases into the air. Given the rapidly rising demand for eco-friendly equipment

around the world in recent years, hydrogen-based construction equipment is expected to help Hyundai Construction Equipment compete in the global construction market moving forward. Furthermore, compared to lithium batteries, which have been marred by structural issues limiting various attempts to increase battery capacity, hydrogen fuel cells are much easier to expand, making them a much more logical choice for large forklifts or excavators. There are many different solutions for electrifying fleets,

IS THERE LIFE LEFT IN INTERNAL COMBUSTION? There are two ways hydrogen can be utilized as a fuel source. It can be burned in a conventional internal combustion engine or it can be used to produce electricity through a fuel cell. The attraction of burning hydrogen is that it utilizes much of the existing diesel engine technology infrastructure. It simply requires that the internal combustion engine be modified to burn hydrogen instead of diesel. Since the infrastructure for the internal combustion engine already exists, alternate fuels that use this technology can reduce initial investment. “It’s expensive to get an electrified product offering,” notes Hayfield. “Just recently there have been a number of manufacturers reviving this concept of hydrogen internal combustion engines,” he continues. “It is not something new. It’s been around for a number of years. But it is getting a little traction now because certain applications within off-highway, in particular, are very difficult to decarbonize. Clearly, there will be pressure to do that somehow. “Battery electric is not going to be suitable for a large excavator. You have to decarbonize, so what do you do? Obviously, a fuel cell is one option. Biofuels or carbon neutral synthetic diesel is another. A hydrogen internal combustion engine is another alternative,” Hayfield states. Fuel storage design on the machines is one of the biggest challenges if the machine is
going to burn hydrogen. “You have to add compressed storage tanks to the vehicle and that adds quite a bit of cost which you obviously wouldn’t have with a diesel-powered engine,” says Hayfield. While burning hydrogen does eliminate carbon emissions, there are still emissions produced. “Primarily it’s water and nitrous oxide. From a greenhouse gas perspective, it is great,” says Hayfield. “Because of the high temperature, you do get nitrous oxides produced. Those are the particulate matters that cause respiratory problems for people. Those can be minimized. You can’t get rid of it completely. If legislators choose to focus on that as something that is going to be banned, that’s a problem.” The cost/benefit ratio of burning hydrogen also remains a question. “It’s going to continue to be expensive to produce hydrogen, particularly if it is green hydrogen,” Hayfield comments. “I am not sure the best use is to burn it. The efficiency of a fuel cell is much higher so it would make more sense to use a fuel cell.”
THE TRANSITION TO FUEL CELLS Many companies have built prototypes that utilize hydrogen fuel cell technology. “The hydrogen fuel cell is gaining quite a bit of traction in very heavy applications,” says Hayfield. “I would expect to see fuel cells being quite an important part of the product mix for that area.” The hydrogen fuel cell solution has the advantage in that it can be a true zero-emissions technology, depending upon how the hydrogen is produced. “We see hydrogen fuel cells and battery electric power as complimentary technologies in a portfolio of zero-emission powertrains,” says Jeremy Harsin, off-highway business director, Cummins Ltd. “There is no one-size-fits-all universal solution. Hydrogen makes sense for larger equipment with high utilization and energy demands due to the charging infrastructure limitations and the size of batteries needed.” Battery charge times are a consideration when it comes to larger equipment. “The long recharging times required by larger equipment can be a
deterrent,” says Harsin. “For heavier duty cycles, fuel cells would offer more flexibility and higher machine utilization. Battery electric power is more suited to compact, lighter duty machines, particularly in the rental sector.” Large machines need to carry enough energy to complete their mission. “Onboard storage is a critical component of hydrogen power to store enough to meet duty cycle requirements of a machine,” says Harsin. “Cummins is investing in storage technology with joint venture
www.ForConstructionPros.com
NPROXX, a world leader in high-pressure hydrogen storage for stationary and mobile applications.” The performance of the hydrogen fuel cell vs. the conventional diesel engine it replaces will be determined by the efficiency of the system design. “The interaction between fuel cells, batteries, powertrain and fuel storage will determine this,” says Harsin. He adds, “Understanding and adapting the overall powertrain system will be crucial going forward. The battery size and fuel

depending on machine size and application. “Hydrogen is an important part of the whole equation,” says Volvo Group’s Lundstedt. “It is a very important answer as energy storage where we cannot rely on electric generation where it happens in a green form, but also to be able to store it and complement the battery electric execution.” Fuel cells are just a different way to power an electric vehicle vs. a battery. “Both of them will play a very important role, where fuel cell electric vehicles have clear advantages in certain areas and battery electric vehicles have clear advantages in other areas,” says Lundstedt.

DESIGN FOR EFFICIENCY Overall efficiency of the machine design plays into the emissions and energy required. Off-road machines are typically hydraulically intensive. “Hydraulics, historically, have been quite inefficient,” says Alastair Hayfield, Interact Analysis. “There’s a big push at the moment to really improve the efficiency of those hydraulic systems.” There are a few emerging technologies such as digital hydraulics and hydraulic replacement with electrified components. “They can bring out some pretty impressive efficiency and emissions reductions,” says Hayfield. So, there is a transition on the powertrain, and that is probably fuel cells, but then there are a lot of technologies that could be applied to the machine to improve overall efficiency quite substantially. “Hydraulics is one area that gets overlook, particularly for off-highway,” says Hayfield. “There are some really neat things that Danfoss and Bosch are doing. We have done a couple of projects with the universities where they are working on the next-generation hydraulics. They are seeing very impressive gains in system efficiency.”

Europe is leading the charge when it comes to driving a hydrogen economy, with European policymakers, the scientific community and manufacturers committing significant resources. The Volvo Group and Daimler Truck formed a 50:50 joint venture, cellcentric, to become a global manufacturer of fuel cells. cellcentric has been tasked with the development, production and commercialization of fuel cells in heavy-duty trucks and other areas. The joint venture has been up and running since March 2021. “We have been talking about hydrogen and the potential of hydrogen for quite some time,” says Lundstedt. “I have been in this industry 30 years and we have always said it is about 10 years away. But now we are really getting here. We see a clear roadmap for execution both when it comes to technology and commercialization. It’s very promising.” Electrification is the way forward. “To put it into perspective, we are talking a lot about electric vehicles — batteries, fuel cells, etc.,” says Lundstedt. “It’s important to put into context that all of those are electric vehicles, with the outcome of electric vehicles that we want to achieve with fossil-free executions, with much lower noise, with reduction of NOx and particulate matter.” Battery electric technology is better suited for shorter distances and lower payloads. “There is an overlap obviously, but when we talk about longer distances and more heavyweight applications, fuel cell electric vehicles will be very well suited, and in particular for demanding long haul applications with a high level of flexibility, long range, forced refueling and high payload,” Lundstedt states. That’s why Volvo Group joined forces with Daimler Truck to create cellcentric. “It will build upon the strengths, to scale faster, to show a clear direction moving forward and make sure

we are investing here and now to hand over a planet for coming generations,” says Lundstedt. “Fuel cells and cellcentric will play a key role and we are excited to have this opportunity.” cellcentric is focused on heavy truck and other heavy commercial applications to produce the power output, durability and modularity the industry demands. “We are reducing the cost step by step in a very concrete roadmap,” says Lundstedt. There are several advantages to hydrogen fuel cells, which Daum outlined during the April 2021 presentation: “Trucks are often used very flexibly. There are non-predictable routes, surprise transportation tasks where you can’t plan ahead and you need an energy source that gives you reach and dependability and, if you need, immediate recharge like what we have today with diesel.” Hydrogen provides this flexibility. Then there are infrastructure considerations. “It’s always easy for the first 1,000 trucks to run on electric and use an electric power grid, but we are looking to a future where 100,000s, if not millions, of trucks need the electric power grid at the same time when 10 million or more cars also need the same power grid,” Daum pointed out. “So, in this sense, we need a second source for energy. That energy is hydrogen. Hydrogen has one big advantage — it scales nicely. The more people that use it, the cheaper it gets.”
CLEAN HYDROGEN NEEDED Hydrogen is currently not necessarily a clean power source. It really depends on how it is produced. “One of the biggest challenges that you have is that most of the hydrogen produced today is called brown hydrogen,” says Hayfield. “It is made from the by-products of the petroleum industry, so it’s not clean. There are carbon emissions associated with it.” So, you are not really decarbonizing if you utilize it as a fuel source. “You are just moving the problem somewhere else down the supply chain.” But hydrogen does have potential. “To provide a truly zero-emissions solution, hydrogen production needs to be green, i.e., produced without direct emissions of air pollutants or greenhouse gases,” says
EARTHMOVING
Harsin. “Without being green, it cannot be a meaningful part of the solution for a zero-emissions future.” He adds, “Cummins is involved in Electrolyzer production, which is used to generate green hydrogen with renewable energy. A recent project is producing up to 8.2 tons per day of low-carbon hydrogen in Bécancour, Québec.” You need to start somewhere. “There are more realistic plans now to move to things like blue hydrogen or green hydrogen,” says Hayfield. “That potentially brings around the ability to use this as a fuel and it doesn’t have any carbon emissions. It’s much more sustainable. One of the key things here is going to be that ramp up of blue hydrogen or green hydrogen and we’re still a number of years away from that.” You need to look at the entire energy chain. “The hydrogen that we sell needs to be green hydrogen as any energy going into a battery electric vehicle needs to be green energy. Otherwise, burning diesel would still be better for the environment than burning coal someplace and then feeding that either as electricity or hydrogen into a vehicle,” says Daum. “Clearly, using hydrogen has potential, but it is only going to fulfill its biggest potential if it can all be green hydrogen, and we’re a long way off of doing that now,” says Hayfield. “You have to start somewhere, but you cannot fix everything at once.”
specifically at pricing for electrified components for offhighway applications,” says Hayfield. “One of the biggest challenges is low volumes. You cannot get the same pricing for batteries that GM or Tesla does. If you go to the manufacturer and say you need 1,000, the price ends up being
three or four times what it is in automotive. That’s another challenge this industry has to face. It is another thing that is going to make electrification or decarbonization very difficult in this space. How many engineering dollars do you want to invest if you are selling a couple thousand units a year?”
In other words, don’t expect an overnight switch to hydrogen fuel cell technology. “The adoption of fuel cells will be gradual over the next five to 10 years as they become not just environmentally but operationally and economically viable for OEMs and operators,” predicts Harsin. ET
INFRASTRUCTURE CHALLENGES Like most alternative energy solutions, hydrogen also faces an infrastructure challenge. Hydrogen generation, storage and infrastructure are some of the key challenges facing the market. “Even with many projects in place to increase hydrogen refueling, that will take time and resources to develop,” says Harsin. “Adoption of hydrogen will likely begin in markets where fueling can be done centrally, such as at home base operations or close to large hydrogen hubs where there is access to affordable renewable power.” The hydrogen infrastructure is the key challenge holding back mass adoption. During Daum’s presentation last April, he explained, “If we would have a working infrastructure, it would be extremely easy to sell 100,000 fuel cell trucks and we would have 100,000 fuel cell trucks on the road. Unfortunately, we will never have 100,000 trucks out on the road without infrastructure.” This will require support from energy companies and politicians to secure the initial investment. Component cost will continue to be an important factor, as well. “We just did a piece of research looking

MARLBORO MOUNTAIN IS ROCKIN’ WITH SPECIAL ATTACHMENTS Marlboro Mountain Construction (MMC) is an all-purpose excavating company in upstate New York that loves a challenge. So, when owner Steve Bianco was approached about building a 12-ft. retaining wall along a cliff overlooking Dead Man Falls as part of a cliff walk trail, he jumped at the opportunity. Bianco has been doing varied construction projects for as long as he can remember. “I grew up on a backhoe, but this company has been in existence since 2000,” he states. “We try to get unusual kinds of jobs, interesting and challenging jobs.” For this particular project, two excavators were used. One was used to pass the Rosetta Outcropping pieces to the other, which then traveled and set them. Bianco and his team had to drill into bedrock and add rebar and concrete behind the block to anchor and add mass to the gravity retaining wall. The project required creativity, patience, the expertise gained from a lifetime of experience and the correct, often specialized tools — an Engcon Tiltrotator and a Werk-Brau Power Grip Bucket.

QUICK COUPLERS ENABLE CORRECT DEMOLITION TOOL FOR THE JOB Improper use of demolition tools is a common cause of failure. Operators are more likely to choose the correct tool for the job if the carrier is equipped with an automatic quick coupler. “We do see the trend where the demolition contractor goes with a fully automatic quick coupler because it makes more sense in their day to day to be changing from a shear, pulverizer, grapple and then back to the bucket,” says Christian Yanes, vice president, region Americas at Steelwrist Inc. The demand for automatic quick couplers in the demolition environment is due to the nature of the attachments. “Safety definitely becomes a bigger issue when it comes to demolition tools because the tools are bigger, the pressures that the machines or the hydraulic tools are working with are higher,” says Yanes. “More things can go wrong.” With the automatic quick coupler, the operator can stay in the cab and no one is required to be on the ground to perform the switch.

In-cab Technology Drives Safety Discourage distracted driving and monitor driver behavior with driver apps and dash cam technology. While mobile devices can help us a lot, they’re leading to some very unfortunate unintended consequences. For example, 40% of commercial driving accidents are being caused by device distraction.
D
istracted and inattentive driving are leading causes of vehicle-related accidents as the influx of mobile technologies competes for drivers’ attention. There are in-cab solutions that not only help minimize multi-tasking during critical drive time, but also detect drowsy driving, aggressive driving and threats from other vehicles on the road. Solutions exist that can help manage mobile technology use while behind the wheel. One example is TRUCE Software. “TRUCE is all about providing employees with the right mobile features and functionality at the right time,” says Joseph Boyle, TRUCE CEO. “It all boils down to the individual employee’s context, such as their proximity to heavy equipment, work group and time of day, for example. Mobile device permissions adjust automatically and in real time as the employee’s environment changes throughout a shift.” What is okay for an employee to do with a device while in the break room, for example, is different from what might be considered appropriate use when driving a vehicle. The company sets its mobile use policy and
TRUCE simply helps to enforce that from a tech standpoint. No monitoring or manual intervention is involved. “Dynamic enforcement of an employer’s mobile device policy based on each employee’s real-time context helps ensure workers are safe and productive, while still giving them the freedom to keep their mobile device on them throughout a shift,” explains Boyle. “At TRUCE, we don’t believe phone bans in work environments are the answer.”
SITUATIONAL APP USE DRIVES SAFETY Trying to limit use through broad company policies has not proven very effective. “A flexible solution is needed that allows you to understand, define and enforce different use policies for different environments,” says Boyle. For example, when an employee is on a jobsite, they may need access to certain applications. When that employee is in a vehicle, access to most applications, except hands-free calling, can be temporarily restricted. “You can use turn-by-turn directions as long as you’re not typing in the address while you are driving,” notes Boyle. “And you can
32 EQUIPMEN T TOD AY | January 2022
listen to your music and podcasts, for example, but your ability to check emails or work orders while driving is withheld until the employee is no longer driving.” The use will be determined by the employer policy. “It’s all about your acceptable use policy,” says Boyle. “How does that change situationally? You define those policies in [TRUCE’s} application and then we bring them to life.” The technology relies on contextual indicators. It is more about context than location. “We are not interested in monitoring where people are. There are tracking technology companies that do that,” Boyle states. “We are interested in making sure employees are getting safe and productive use out of their technology. It’s about getting what you want out of the mobile device and not having the by-products. “We go after the root cause of the issue, which is we’re addicted to our devices. We stare at them constantly — most of the time not even realizing that we’re doing it,” he comments. When employees can’t access unnecessary apps, that behavior changes. “They put the
phone away and focus on the task at hand.” The results speak for themselves. “Our customers typically see between a 30% to 40% reduction in accidents after deploying TRUCE,” says Boyle.
DASH CAM TECHNOLOGY KEEP DRIVERS ALERT Beyond mobile technology distractions, there are other factors such as driver fatigue and aggressive driving habits that can lead to increased risk. In-cab camera technologies have proven an effective solution to address these issues, as well as protect drivers and companies from liability from accidents caused by other roads users. “Camera technology has been around for some time,” says Mayank Sharma, head of global product management and UX, Teletrac Navman. “With the advent of the smartphone, it’s become mainstream on the consumer side and it is everywhere. Obviously, there is overflow into the commercial side.” It started with recording videos on SD cards and has progressed to connected dash cams that give real-time access to video data in the cloud using mobile apps or the web. “The benefits
www.ForConstructionPros.com
are that you can see all the way from prevention of accidents to reducing accidents,” says Sharma. On one side, this technology proactively reduces accidents. “The other side is more incident management or incident capture so that you can coach drivers, which will ultimately results in safer driving and on-road behavior,” Sharma explains. “Those are the two spectrums, but in the middle there are a ton of other benefits for the fleet manager.” Driver retention is among these benefits. “If your fleets are generally safer you can retain drivers longer,” notes Sharma. Insurance is another benefit. “There is actually a connection between using this data and going to your insurance company to say my fleet is safer and my premiums should be lower based on how my drivers drive,” Sharma points out. Maintenance costs can also be reduced. “How you drive safer is by not braking too much, not cornering too harshly,” says Sharma. “That helps you with maintenance costs, which is sort of an implicit benefit, as well as fuel reduction cost. So, today there are a whole host of benefits that come from adopting dash cams, and especially connected dash cams, in your fleets.” Dash cam technology presents a clear picture of driving events. “First of all, video provides visual proof and context around telematics-triggered events,” says Andrew Rybak, business development manager, marketplace, Geotab. “For example, it can reveal what the driver was doing when a harsh braking event occurred. Also, the dash cam can be used to exonerate a driver. Video captured by dash cam can be used as evidence when a driver is incorrectly deemed at fault for an accident.” Omnitracs reports that 85% of collisions are not the fault of the commercial driver. But dash cam technology does increase safe driving behaviors, as well. “The installation of a dash cam can immediately reduce accidents or close calls through alerts for unsafe behavior,” says Rybak. “Some drivers will also be more mindful knowing that a camera is monitoring their driving.” Not all dash cams are the same. “There are wide varieties

of technologies that range from dash cams that simply record audio and video to capture information in and around the vehicle, to more proactive safety systems that are integrated with the vehicle,” says Jason Palmer, GM of transportation intelligence, Omnitracs. “These safety systems will alert the driver if they are distracted, fatigued, following too close or unsafely maneuvering the vehicle. Events from the advanced systems can then be analyzed by driving experts to determine if the driver needs additional training.” There are reactive and proactive systems. “Reactive systems that simply record what is happening in and around the vehicle are primarily focused on recording situations for exonerating the driver,” notes Palmer. “For those systems that are more proactive in measuring driving performance and alerting the driver, they can have an immediate impact in reducing collisions.” The driver-facing camera is important for implementation of proactive systems. “Dash cam technology can provide proactive driver alerts for distracted or drowsy driving as long as there is a driver-facing lens and the driver system monitoring (DSM) is enabled,” says Rybak. “For fleets unwilling to capture what is going on inside the cabin, they do have options. They may install a road facing-only dash cam, block
the driver-facing camera or use the driver-facing camera as a sensor that does not capture video. However, the most effective approach to keeping everyone safe usually includes a road- and driver-facing camera.” The inward-facing camera is very focused on driver behavior. According to Sharma, phone usage is the most commonly recorded violation captured, followed by seat belt use. The camera is able to detect if the driver is wearing the seat belt or not. The return on investment in dash cam technology should be immediate. “We expect our customers to realize immediate results when deploying video-based AI (artificial intelligence) technology,” says Rybak. “For example, AI-based video telematics can recognize when a driver is doing something risky, such as using their cell phone or following too closely, and immediately alert the driver.”
RECORDED INFRACTIONS DRIVE IMPROVEMENT Cameras will give you a true picture of what is happening in the fleet. “With cabin-facing dashboard cameras, the most common events typically captured are cell phone use, drowsy driving, eating or drinking distractions, improper seat belt use and tampering with the camera,” says Rybak. “With road-facing cams, they can capture
forward-collision warnings, stop sign violations, risky lane departures and unsafe following distance.” Systems are becoming more sophisticated. “The most basic triggers are based on hard braking, cornering and speeding,” says Palmer. “More sophisticated systems will leverage computer vision and AI to measure driver inattention, fatigue, following distance, collision warning, U-turns and speeding. “Safety systems are now also leveraging streaming data in real time to measure impending inclement weather and can advise the driver when they may need to reduce speed,” he adds. “It can also monitor vehicle health and the location of a vehicle to dispatch maintenance when there is an issue where they are parked unsafely, ultimately to quickly intervene to get the driver to a safe location.” AI technology can gauge the condition of the driver, as well. “We are able to track the iris, the eyeball direction where you are looking,” says Sharma. “Those technologies are available and they’re pretty mature. You are able to pretty accurately detect if the driver is distracted; it’s called engaged tracking. But there is also head tilt tracking. If your head is tilted down, you really can’t focus on the road. You are focusing on something else.” Audible alerts are used to get the driver re-focused.

“It is really about using coaching and transparency with your employees,” he continues.

The Lytx DriveCam device mounted on the windscreen contains a forward-looking lens and a lens focused on the interior of the cab. It also contains an accelerometer and other components to record data.
Lytx DriveCam Event Recorders detect risk using a combination of sensors such as accelerometers, machine vision and artificial intelligence. “Accelerometers allow us to capture unsafe driving events such as hard acceleration, braking, speeding, cornering and high G-force events,” says Ofelia Chernock, senior product marketing manager, Lytx. “Machine vision and AI provide additional vehicle and driver movements that can help identify risky and distracted driving. “Traditional sensors capture risky and inefficient driving. Lytx technology monitors for patterns of persistent driving behavior and selects representative highlights of video
that users can use as coaching opportunities,” Chernock explains. “Events are triggered when the DriveCam Event Recorder sensors detect certain behaviors, unusual or abrupt movement or when prompted by third-party ADAS signals.” The results again speak for themselves. “Typically, a Lytx

client will see results within the first few weeks of implementing the video-based safety technology,” says Chernock. “In a recent study conducted with more than 1,500 vehicles this year, fleets saw a 50% reduction in handheld use within days of implementing our technology, a result that was sustained for more than 29 weeks. “By addressing the root causes of collisions and near collisions, our clients have seen substantial reductions in claims, with many seeing up to 80% reduction in claims costs within a year of installing our system,” she adds. “Our clients can see a 300% ROI and up to 50% reduction in collisions.” Dash cams can serve as a deterrent simply by their presence. “Drivers are more cautious,” says Sharma. “The dash cam is right there. There is an immediate drop in risky behavior.” But in order for successful implementation, you need to communicate with drivers. “It is just transparency. You need to be open with your drivers about what you are actually recording and for what purposes.” Many of the concerns drivers express about this technology are the same expressed 15 or 20 years ago surrounding GPS tracking technology. “That concern is still there, but I think largely now people understand the benefit,” Sharma comments. “I think camera technology is going down the same path.
Dash cam technology adds a new level of capability to telematics data. “Traditional telematics software that merely identifies G-force triggers, such as excessive braking or swerving, produces results that do not tell the whole story. Video evidence from dash cam technology exposes more than regular telematics could ever do,” says Chernock. “This is where we have seen big gains in safety and productivity over the past 20 years. Once you layer on technologies like machine vision and AI, the value of video grows exponentially. We can now identify whether a driver is distracted by their phone, drives through a stop sign, forgets to fasten their seat belt, is smoking while transporting hazardous or combustible cargo and so much more. “In addition, understanding what happened in the leadup to an unsafe or risky event, for example, enables fleet safety managers to paint a complete picture of the driver’s risk profile as well as the fleet’s risk profile — all the while, moving toward an improved safety culture,” she notes. “With precise, accurate data, fleet safety managers can proactively detect risky driving habits and correct them through personalized or self-coaching, reducing the likelihood of potentially dangerous road incidents.” Real-time monitoring through integrated technologies can proactively prevent accidents. “Only advanced safety systems that incorporate computer vision, telematics and sensors can consistently measure driver alertness,” says Palmer. “The (Omnitracs) SmartRecorder4 or SR4, our 2nd-generation system, measures driver distraction to alert drivers in real time, as well as notify the driving expert if the situation persists so that they can proactively manage the situation.”
www.ForConstructionPros.com
But there is a balancing act. Too many alerts coming from multiple devices can actually cause the warning devices to become the distraction. “Because we are starting to see a breadth of safety alerts in the vehicle, it is important to integrate with the vehicle to only alert the driver from one system,” Palmer acknowledges. “For example, if the vehicle has a forward collision warning system, the dash cam will not confuse the driver by offering up duplicate alerts at the same time. With the growing breadth of potential alerts that may be given to the driver at any time, visual or text to speech alerting ensures that the driver clearly understands what they are being asked to do at that time.” Dash cam technology is available for all fleets. “Every fleet can benefit from dash cam technology since there is not a fleet that is 100% risk-free,” says Rybak. ROI varies with each client’s unique situation. There is no one-size-fits-all when it comes to dash cams or video telematics. “We have seen interest from some fleets that are prone to legal or reputational risk, such as those with branded trucks. Another group of companies that realize the biggest return on investment are the self-insured vehicle fleets, as they pay the full cost of each and every accident.” Dash cam technology helps reinforce a safety culture. “It becomes part of the larger story and safety culture for the organization,” says Chernock. “Many of our clients find both hard ROI in the form of fewer claims, lower vehicle maintenance costs, better fuel efficiency and reduced workers’ compensation claims. But they have also found ‘soft’ returns as well, such as a stronger safety culture where workers do the right thing even when no one is watching or better communication and trust between drivers and fleet managers.” There are many distractions as today’s drivers attempt to multi-task, and mobile technologies often compete for attention. In addition, drivers often face tight deadlines, which can lead to aggressive driving. As we have shown, there are in-cab technology solutions that can help discourage aggressive driving while keeping your drivers focused on the road. ET

Troubleshooting and Diagnosing Advanced
Bendix
SAFETY SYSTEMS How to minimize vehicle downtime in the maintenance bay. When troubleshooting, start by running a diagnostic software tool that shows a system view of what’s on the vehicle that includes key vehicle components.
“The best tip we can give for diagnosing faults in higher-level safety systems... is to make sure you’re looking at the entire truck first.” — Brian Screeton, Bendix
A
dashboard warning light can send a simple and clear message: Something on your truck needs to be checked. But on today’s complex vehicles — and particularly when it comes to their increasingly interconnected safety systems — knowing exactly how and what to check can mean the difference between hours and days of costly downtime. “Sometimes the first response to an indicated electronics problem within collision mitigation systems may be to start removing and replacing components,” says TJ Thomas, Bendix director of marketing and customer solutions - controls. “But there are plenty of times when a component isn’t the issue, so we recommend starting by running a diagnostic software tool that shows a system view of what’s on the vehicle that includes key vehicle components, as well.” This assessment can give the technician a quick overview of what’s going on, especially when more than one component shows similar active Diagnostic Trouble Codes (DTCs), such as J1939 communication errors. The technician can look for frayed wires, corroded connectors or blown fuses. Equipment such as cameras and radar should also be checked to make sure they’re not obstructed by things like road debris, snow and ice. Some DTCs are self-clearing.
36 EQUIPMEN T TODAY | January 2022
“This means that simply by fixing the situation — removing the obstructing debris, for instance — the indicator lights and associated fault codes will be deactivated,” says Thomas. Service data sheets should call out these types of DTCs so the technician can be aware of what kinds of conditions generate them. If this initial approach comes up empty and it looks like the problem is something a bit deeper, then having the right tools and the know-how to use them is the key to getting trucks back on the road and in good working order as quickly as possible.
IT’S ALL CONNECTED More than ever, the various systems across a commercial vehicle are intertwined, with multiple electronic control units (ECUs) sharing necessary information over the J1939 network. For example, automated transmissions depend upon information from the engines to operate properly and at their highest efficiency. “The best tip we can give for diagnosing faults in higher-level safety systems like adaptive cruise control is to make sure you’re looking at the entire truck first,” says Brian Screeton, Bendix supervisor - technical service training. “If a driver reports an adaptive cruise fault, then a technician might connect the diagnosing tool just to the radar.
There may not be an active fault there, but they wind up going down a rabbit hole and spending time trying to troubleshoot inactive faults when really it turns out there’s an engine problem driving the whole thing. Faults in one system can be driven by a completely separate system component.” Because of that possibility, Screeton recommends that technicians run a comprehensive DTC report as a benchmark to know the vehicle’s full status before making any changes to the truck.
THE RIGHT TOOLS Before assuming that an advanced safety system active DTC means something is wrong with that system, technicians should make sure they’re using a tool that gives them visibility to any active DTCs being broadcast on the vehicle’s J1939 network. Bendix ACom PRO is one such tool. But the important thing is having a diagnostic tool that shows DTCs of the full vehicle. “A tool that shows you an active DTC on the engine retarder, for instance, tells you that you need to troubleshoot that issue first because it may be the cause of your adaptive cruise control DTC,” Screeton points out. “In fact, we recommend technicians always troubleshoot any active engine faults first because of the way they impact other system faults.”
www.ForConstructionPros.com
ADDRESSING ADAS Advanced driver assistance systems are deeply integrated through their communications with systems like the brakes, engine and transmission. They include their own ECUs and sensors such as camera and radar units — components that require an extra degree of caution. “Physical components of stability and collision mitigation systems generally require maintenance only if changes have been made to certain parts of a vehicle. If you do a front-end alignment or work on the steering linkage, for example, then you’ll need to recalibrate the steering angle sensor according to the manufacturer’s guidelines,” says Thomas. “Before a technician adjusts a camera or radar, we stress that they address any J1939 faults or engine faults first. You don’t want to have to take time replacing or realigning a sensor if it’s not necessary.” Modern diagnostic tools increasingly have the ability to make changes to systems, from calibration to reconfiguration. Bendix strongly recommends that any individual technician confirm with maintenance or fleet management before making any performance changes to ensure the result will be consistent with what the fleet wants.

SOFTWARE CUTS COSTS AND ACCELERATES SITE CONTRACTOR’S GROWTH D
an Vallencourt, thirdgeneration leader of family-owned Vallencourt Construction, says its field peoples’ ready adoption of new project management software in 2019 powered the biggest steps in the company’s climb to doubling its revenue over the past five years. “At 10% growth per year when you’re around $60 million (where his company was in 2016), that’s $6 million. Ten percent growth at $115 million (as seen in 2019 and 2020) was almost $12 million,” Vallencourt notes. “The percentage is important but so is the overall dollar amount. You have to be able to finance that work to eat until you get paid for it. “It certainly helps to be able to decide we can handle this extra work because I know what’s going on,” he adds. “I have a very clear picture, good data and I know I can control my costs.”

and for 14 years, Vallencourt Construction could easily export not only employee and machine time but also pipe quantities and production that project managers
personnel’s experience with daily data collection made a big difference in getting the platform up and running quickly when the going got tough in 2020.
Vallencourt Construction is primarily a residential sitework contractor with 55 crews and more than 400 pieces of equipment working in northeast Florida.
INNOVATION IN THE NICK OF TIME Demand for the Green Cove Springs, FL (just south of Jacksonville) sitework contractor’s services has been strong for more than five years. About 85% of the company’s business is for residential developers, and Vallencourt has been letting the company gallop. But the COVID-induced residential run, in the face of all the pandemic’s other construction impacts, introduced the kind of uncertainty that caused many business owners to tighten up on the reins. Coincidentally, Vallencourt Construction was replacing a homegrown time tracking software system about the time the pandemic broke, and the

submitted daily from the field to the accounting system. Advancing computer operating systems threatened to render the timesheet manager obsolete, so the B2W One Platform was chosen to extend and integrate the company’s cost control. Field

“We had a big benefit that our culture was already halfway there; they had basically already been doing what Track does,” says Vallencourt. “We did a twoweek trial run starting in March of 2020. We did two weeks of ‘submit your time through B2W
PROFIT MAT TERS
and submit your time through our old system.’ They had to do double duty, but we just wanted to make sure all the kinks were ironed out and knock out any questions. “It was almost universally accepted immediately. We issued everybody an iPad and gave them a tool to do their work so much easier,” he adds. Vallencourt cites three major advantages to the software shift: ˜ Tactical: “You’re able to copy field logs from one day to the next. You select all your jobs, select all your employees and your equipment and Track will automatically populate into the next day if you want it to,” he points out. “You can do multiple jobs in one field log.” ˜ Time management: “On an iPad, it’s web based and it’s
equipment, it updates the entire system,” he notes. The machine moves to the new job’s fleet in Track and shows up in the correct location when accessed from Maintain.
BIG SAVINGS MANAGING MAINTENANCE Managing equipment costs turned out to be a significant attraction. The company had always kept track of big categories of costs such as parts, service calls, repairing equipment damage and the like. “But it was just one big blob — a black hole of money,” says Vallencourt. “We had no idea how much each piece of equipment was costing us. “Through exploring Maintain, we realized we can get what we want from the mainte-
the same repair request, service schedule and cost record information. Vallencourt Construction owns virtually all of the equipment it uses — about 400 pieces of heavy equipment and 120 licensed vehicles. Without better records of individual machine costs, it would have been cycling machines out of the fleet based on simple hour meter standards. “Okay, this machine has this many hours on it, time to go,” says Vallencourt. “But now that I have the data, I can look at these pieces of equipment and see if they’ve had some kind of a big expense — maybe an undercarriage job or something.” The company can decide to make such a machine last a little longer on the jobsite to recoup some of that investment, or if a particular machine has a poor
VALLENCOURT CONSTRUCTION PROFILE Vallencourt Construction is a sitework contractor with about 85% of its work coming from single-family residential home developers in about a 100-mile radius around Jacksonville, FL. “We clear raw land, lay the storm drain, water main, refuse main — any kind of underground utilities except for electric – grade the lots, and build the roads,” says Dan Vallencourt, the family-owned company’s thirdgeneration leader. The company has approximately 440 employees, 55 crews, 400 pieces of heavy equipment and 120 vehicles.
syncing throughout the day. So, they can start their field log in the morning, add to it throughout the day and then submit it at the end of the day,” he explains. ˜ Integration: “In Schedule, if we move a piece of

reliability record, choose to move on. “Instead of waiting another year, let’s get rid of it now so we don’t spend any more money on it,” says Vallencourt. “There are two places where Maintain saved us probably the most money that are easily identifiable,” says Vallencourt. “One is warranty tracking. We buy extended warranties with all of our equipment. With Maintain, I started catching invoices for repairs that were on a machine that’s still under warranty. I can’t tell you how many invoices, especially in the early days. The
www.ForConstructionPros.com
dealer is not doing it on purpose; it’s just their processes aren’t that great for checking it. “I got everybody tightened up now, so I don’t see as many. I don’t know exactly how much we saved, but it’s hundreds of thousands of dollars just from warranty catching,” he states.
IMPROVED UTILIZATION SAVES MILLIONS Another easily identifiable savings was in improved machine utilization. “With a company our size, it was really difficult to know if a machine was being utilized at a jobsite, so we would rely heavily on our foreman to let us know if a machine that we have a need for elsewhere was being used. Well, human nature in the construction industry is that nobody likes to give up their equipment,” Vallencourt acknowledges. “If I take something from their site, they don’t believe it’s ever coming back. But they don’t know the bigger picture. I need this machine for another jobsite and I don’t have anything else available. “When we first started with B2W, we would have things on rent that weren’t being used enough, and I’d also have my own equipment that wasn’t being used enough. It was just a disaster,” he says. “We’re trying to get to where every single thing we have is being utilized as efficiently as possible. “With the tracking of the hours, I can run a report in two seconds and see, ‘Hey, this machine had 10 hours on it last week.’ It could have been down, the operator could have been out, the job could have just been in a transitional point or it could have rained four days. All it means is that if a need arises for a machine like that on another jobsite... I can say, ‘I know you’re going to need it in a little while, but this other job needs it now. I can bring it back as easy as I can take it,’” Vallencourt explains. Fleet utilization improved so much with about a year of these kinds of conversations that Vallencourt figured he could cut his annual machine purchasing in half. In a 2021 in which the company is on track to grow more than 10%, they expect to save about $10 million buying less equipment. And the One Platform makes it easy to track
how equipment spending relates to project performance. “B2W gives us the tool to actually see in real time exactly what is going on,” says Vallencourt. “We can run a quick report that tells us the ratio of how much we have invested in equipment vs. how much revenue we made. And we track that through the years to see how it is trending.” Controlling capital expenditure on equipment is crucial to Vallencourt Construction, particularly in the company’s growth phase. Halving that budget is a bit of a stretch. But as Vallencourt points out, “That’s how you go out of business, right there — you grow too fast and you can’t pay your bills.” ET

Why Equipment Managers Should START MIGRATING TO 4G TODAY Despite the challenges of transitioning to 4G, the long-term issues will be much more severe.
F Fleets using 4G telematics will have the edge in data connectivity and transfer speed, meaning that companies will have insights that are closer to real time and far more accurate.
or the heavy construction market, telematics has been a game changer as it enables the consistent tracking and monitoring of both off-road vehicles and assets such as cranes, heavy equipment and lifts. By using IoT devices to monitor GPS location, vehicle speed, engine data and diagnostics, driving behavior, the usage of accessories and other valuable information, telematics
provides fleet managers the visibility they need to ensure the safety, efficiency and productivity of their vehicles and equipment. With the ability to run on cellular communications networks — particularly 3G networks — telematics devices are able to operate even when vehicles and equipment are out on remote worksites, which is a major benefit for the construction industry.
Unfortunately, all major cellular service providers, including AT&T, Verizon, Sprint and T-Mobile, are slated to shut down their legacy networks in 2022. This means that soon 64 million 2G and 3G devices, including the 3G-enabled telematics devices that many businesses have come to count on, will face the sunset (“The Sunset of 2G/3G Is Coming. Is Your Business Ready?”, https:// bit.ly/3x2iTrj).
SUNSET, SHORTAGES AND DISRUPTIONS IMPACT INDUSTRY While shuttering these legacy networks will enable service providers to reuse existing spectrum so that they can provide additional capacity for 4G and 5G networks capable of providing increased speeds and data connectivity for users, this transition will not come without challenges. Fortunately for some companies, the migration to 4G and 5G is already underway. For

TECHNOLOGY TRENDS
KEY CONSIDERATIONS FOR TRANSITIONING TELEMATICS DEVICES Upgrading to 4G equipment is easier said than done, since there are several considerations one must take into account before hastily or carelessly switching out old telematics devices. Generally, functioning equipment generates money for the owner. Replacing operational 3G-capable telematics devices will cause logistical problems each day that a vehicle or piece of equipment is down, costing the owner revenue and reducing productivity. Similarly, the global supply chain crunch has made it difficult to find replacement machinery, straining fleets already at capacity.
Replacing telematics devices inside equipment will result in significant stress for most businesses, both large and small. Smaller companies may find replacing their hardware components to be particularly challenging. Having a sizable amount of 3G-connected equipment could mean losing visibility to machinery in the coming months because of issues related to hardware replacement, including trouble finding downtime for equipment and even connecting with qualified installers to replace or upgrade that equipment. Larger companies with even bigger fleets may want to invest in a second or even third telematics partner that can integrate their data feeds into software platforms or ingest data from their existing telematics partner. Such an investment would provide a single, streamlined and convenient source for managers to view all their machine-processed data. For example, while traditionally many off-road fleets were fixed with an original telematics vendor and therefore would need to adapt truck-specific devices for machines, over the years, various leaders in the telematics space opened the ecosystem with vendor-agnostic software capable of supporting and pulling together different hardware. This has provided companies and fleets the opportunity to utilize more than one dedicated hardware partner to help populate their software systems with location, engine hours and other basic machine data so that they can best manage and maintain their equipment. Having access to more than one telematics or connectivity provider would enable some of the companies with expansive off-road equipment fleets to better navigate the 3G shutdown and semiconductor shortage.
DON’T PUT OFF THE TRANSITION With the 3G sunset in full swing, equipment managers, from big and small companies, need to begin coordinating with their telematics partners to upgrade their asset tracking solutions with 4G or 5G devices. Otherwise, users of legacy telematics devices will experience service disruption, downtime and lost revenue, especially in rural areas where the connection is weakest. In addition, if necessary, equipment managers may need to consider alternative telematics vendors, since some vendors have not adequately prepared for the 3G sunset, and few providers, if any, were ready for the global chip shortage. As a result, many telematics vendors do not have enough inventory to help their clients transition to 4G. It is important that equipment managers have visibility into their telematics providers’ 4G inventory so that they can make alternative plans if necessary.
All major cellular service providers are slated to shut down their legacy networks in 2022. This means that soon the 3G-enabled telematics devices that many businesses have come to count on will face the sunset.

others, the closure of 3G cellular infrastructure will leave them unprepared and ultimately disconnected, since 3G-powered equipment, including telematics devices, will cease to function at all. Further complicating an already difficult situation for equipment managers is the global semiconductor shortage. Supply chains across industries are feeling the stress, with one report finding that the shortages will cost the global automotive industries $210 billion in revenue in 2021 and the loss of 7.7 million units of production (CNBC, https://cnb.cx/3Fyr8yo). Likewise, pandemic disruptions, the boom in demand (via e-commerce), plus the lack of workers, equipment and space continue to make the already complex supply chain challenges even worse (Business Insider, https:// bit.ly/3Fu5IlS). The 3G shutdown coupled with the semiconductor and supply chain issues should serve as a wake-up call to equipment managers to start migrating their devices today.
LONG-TERM 4G/LTE BENEFITS Although the chip shortages and 3G sunset place considerable pressure on businesses, they can look forward to the benefits of 4G/LTE devices. Fleets using 4G telematics will have the edge in data connectivity and transfer speed (Transport Dive, https://bit. ly/3x6jube), meaning that companies will have insights that are closer to real time and far more accurate. While some fleets will hover in between 3G and 4G devices due to the complexities of transitioning, those that do not convert will experience a decrease in performance. In the end, experts concur that the benefits of upgrading to 4G will far outweigh any short-term disruptions to the bottom line. Steven Berube is senior business development manager at Geotab. ET

Roller operators need to understand their important role in the paving process, as compaction is the last step in laying down a quality pavement.
How Operator Training Impacts COMPACTION PERFORMANCE
SAKAI Americas
Proper performance by your crew on the roller can help maximize mat quality.
Roller operators need to be properly trained to understand the effects of changing amplitude and frequency on a steel drum roller and how these changes affect the ability to reach density, maintain smoothness and a roller’s speed to keep up with the paver.
A
good paving job will have a smooth, dense appearance that looks flat and tight without any gaps between the aggregates at the surface. We all know that appearance doesn’t just happen.
There are a lot of factors that affect mat quality. The paver, asphalt mixture and even the distance from the asphalt plant to the jobsite all play a role in achieving optimum mat density. But the last equipment to touch the pavement is the rollers, and their operators have the greatest influence on smoothness and those all-important density numbers. “Roller operators need to understand their important role in the paving process, as compaction is the last step in laying down a quality pavement,” says Eric Booth, product training and marketing manager at Sakai. “They need to be observant in order to monitor their machine... watching asphalt temperature, water tank level, DEF tank level, status of the DPF and if any asphalt is being picked up by the drums, etc.
“The plant, milling machine and paver can do everything correct,” he adds, “but if the roller isn’t on the mat at the right time, or not maintained correctly, they could get density issues that lead to early failures and potentially impact any guarantees the contractor may have made.”
TRAIN FOR SUCCESS To be successful in today’s competitive paving market, asphalt paver and roller operators must acquire a deep knowledge of the equipment’s features and put this knowledge into practice on the jobsite. With long-time equipment operators retiring at a high rate, the next generation of operators must receive in-depth training on the equipment in order to meet project specifications without costly rework, so companies can maximize equipment ROI.

“Untrained personnel can cause not only bad/inadequate/ undesirable results in the compacted surface, but could also be a danger at the jobsite, potentially causing damage to the equipment or, worse, causing harm to other personnel,” notes Bert Erdmann, product manager compaction and assisted systems, BOMAG Americas. “Untrained roller operators potentially could cause undesirable results or permanently damage the material.” Over and under compaction of the asphalt are common mistakes operators can make and can adversely impact the final product. “Under compaction would most likely result in inadequate densities, which could potentially result in fines or rework, depending on what the job specification requires,” Erdmann says. “Over compaction often results in breaking the aggregate,

calculation for the operator automatically based on the frequency setting,” Mansell notes. Operators should be trained to understand the relationship between impacts per foot and roller speed as it is critical to maintain smoothness on a job.
TRAIN FOR OPTIMIZED MACHINE USE Operators should be trained/ given the knowledge to overcome some of the hurdles that can crop up on a project, such as difficult weather conditions, clumpy mixes, extremely thick or thin lifts, joining of hot and cold lanes, etc. This will help ensure the machines are being used to their fullest potential. Most roller manufacturers, in conjunction with their dealers, offer training for end users of their equipment. That training is available in a variety of forms, including group seminars, hands-on courses or one-on-one training on the jobsite or at the manufacturer’s training grounds. “Operators not only need to understand these relationships between amplitude, frequency
and impacts per foot... they must understand how to change these settings on the roller they are operating,” Mansell advises. “This sounds simple, but all manufacturers have different methods and combinations of how to change amplitude and frequency. Some changes are made by switches at the operator’s station, while other changes are made on the drum itself and, further, a combination of the two. Understanding how to make these changes is not always intuitive if you have not been properly trained. “It can be very challenging for operators, especially when they are on different rollers from day to day and job to job,” he acknowledges. “All manufacturers offer charts and ‘cheat sheets’ on how to change these roller settings. Ask for these guides and stick them on the roller somewhere obvious for the operator to review, and laminate them to make them weatherproof.” Don’t forget to teach safety best practices to your operators. According to Erdmann, operators should know:
˜ the functionality and prop-
er use of the controls on the roller, ˜ proper rolling techniques and best practices/commonly applied rolling patterns, ˜ and proper use of water — just enough to keep material from sticking, but not too much so the asphalt mat doesn’t cool down too fast.
TRAIN ON TECHNOLOGY TO SIMPLIFY OPERATIONS Manufacturers of equipment have been hard at work trying to simplify and standardize many operations, including compaction. The main technologies that are available to help operators achieve optimal compaction are pass count mapping and temperature mapping, often collectively referred to as “intelligent compaction.” “Intelligent compaction often includes some type of stiffnessmeasuring instrument, most commonly an accelerometer mounted near the drum of the roller to give an indication of material stiffness by measuring the rebound of the steel drum
“Roller operator training is a three-pronged relationship between amplitude, frequency and impacts per foot... on a steel drum roller.” — Todd Mansell, Caterpillar

Wirtgen America
which would ultimately lead to premature failure.” For example, water can enter the asphalt layer and freezing conditions would cause the mat to fail, which could lead to potholes, etc. Under compaction means the pavement is more permeable to water infiltration from above or below the pavement. Longterm exposure to water will strip the asphalt cement bonding the aggregates together and cause the pavement to ravel or fall apart. Over compacting results in pavement that has no internal, interconnected air voids or air space, so when ambient temperatures increase or decrease, there is little or no room for expansion or contraction of the asphalt cement (binder) in the mix. In hot weather, the asphalt cement flushes or bleeds to the surface, which can result in instability of the mix or susceptibility to rutting. Operators need to know how to properly compact the mat to avoid both. “Roller operators are often ‘on their own’ on the job to work with the quality control personnel who are measuring density using a nuclear or nonnuclear gauge. So, it is important that operators are properly trained to understand the effects of changing amplitude and frequency on a steel drum roller and how these changes affect the ability to reach density, maintain smoothness and roller speed to keep up with the paver,” says Todd Mansell, product application specialist, Caterpillar, Inc. “Roller operator training is a three-pronged relationship between amplitude, frequency and impacts per foot, or roller speed, on a steel drum roller,” he continues. “Operators should always try to maintain a minimum of 10 impacts per foot to achieve density efficiently, but equally important, to meet or exceed smoothness specifications for IRI.” Mansell says the simplest calculation is to take the roller frequency setting and divide by 10. For example, if the roller is set on high frequency at 3,800 vpm, then 380 fpm (3,800 / 10 = 380) should be the roller’s maximum ground speed — or 380 / 88 = 4.3 mph. “Most rollers on the market today have a gauge indicating the impacts per foot, so the roller does the

during the compaction process,” Mansell says. “The most valuable and useful tools for operators today are pass count mapping that keeps track of the number and location of roller passes and displays it to the operator in real time during the rolling operation, and the temperature mapping that helps operators stay in the proper temperature range, or zone, for optimal compaction.” BOMAG ECONOMIZER provides a stiffness gauge to the operator with direct “traffic light-type” feedback of the current status of compaction. More sophisticated systems such as ASPHALT MANAGER take it up a notch by reducing the drum output automatically to prevent over compaction. “BOMAG’s BOMAP Connect is the next evolution in Intelligent Compaction,” Erdmann says. This subscriptionbased cloud solution connects the BOMAP app with the ability to plan, track and document multiple compaction projects. BOMAP-equipped rollers can effectively “see” each other and the projects and data exchanged with the ability to connect multiple rollers with each other on the jobsite to provide a visual compaction map. “The operator [on the] machine, the supervisor on the jobsite and even your project manager back at the office have instant connection to your job’s compaction status.” Having visibility like this helps ensure operators have real-time information on their compaction efforts so they can make adjustments accordingly. “Roller operators are the last ones on the mat, so they normally are first to be blamed if something goes wrong,” says Tim Kowalski, HAMM application support manager at Wirtgen America. “Technology today is much more sophisticated and designed to assist operators with consistency of operations, while also ensuring they are doing the job correctly.” Intelligent compaction technology has been instrumental in helping contractors understand and better manage density. Manufacturers have worked to make the data visible and easily accessible while the machine is in use. “Intelligent compaction on HAMM rollers features colorcoded pass mapping,” Kowalski
BOMAG Americas
C O M PACT I ON E QU I P M E N T
says. “Operators can tell the number of passes they have completed and where they have already been on the mat so they know what areas have already achieved compaction. They can also tell where to stop and start on the mat, which is especially helpful during night work.” Other technologies are also available to help operators achieve smoothness goals. “There are a number of technologies to aid the roller operator in getting density, some being more high-tech than others,” Booth says. “Sakai offers an Exact Compact Meter to show the operator which speed gives them the appropriate impacts per foot. Rollers that utilize oscillation can hit density and smoothness in no-vibration areas. Though density is goal No. 1, the compaction crew can’t forget about smoothness or roller efficiencies either. More states are setting smoothness requirements as part of the specifications, and getting density and smoothness in as few passes as possible is important.” The technologies and best practices for construction of asphalt pavements are
48 EQUIPMEN T TOD AY | January 2022
constantly changing. Staying on top of training your operators will ensure your efforts will be successful. “Training should be a never-ending process,” Kowalski emphasizes. “As manufacturers,
we want to make sure companies are getting the most out of the equipment. We want to train operators, foremen, superintendents and even the owners on these machines and what they are designed to help with.” ET
Untrained roller operators potentially could cause undesirable results or permanently damage the material.
SET THE STAGE When teaching your operators proper rolling techniques, keep these tips in mind: • Maintain proper speed — Roller speed has one of the greatest influences on mat quality. Driving too slow can over compact the surface; driving too fast can leave gaps and compromise safety if the operator gets too close to the paver. Using the correct speed will also help to maintain the appropriate impact spacing to prevent washboarding. For most jobs, correct spacing is between 10 and 14 impacts per foot. • Monitor mat temperature — Typically, asphalt comes out of the plant at about 300° F. At that temperature, it is relatively viscous and liquid and is readily compacted. As it cools, the asphalt firms up and compaction becomes increasingly difficult. At about 100° to 150° F, it has cooled enough that the aggregates no longer move. A good operator will understand the temperature range they must work within and adapt accordingly. • Determine when to use vibratory and static modes — Vibratory compaction creates shock waves that compact from the bottom up, while static compaction works from the top down. Most manufacturers will recommend that you roll in vibratory mode right out of the gate. For most jobs, you will use a combination of compaction modes, starting with vibratory compaction and finishing with static. With vibration, you’re getting the desired density, and with static you’re finalizing the compaction. • Select the right amplitude — Generally, amplitude settings are determined by the depth of the lift. Machines with variable amplitudes allow the operator to fine tune the setting to the mix. Lower amplitude settings are recommended for lifts of 2 in. or less; higher amplitude settings should be used for deeper lifts. • Avoid sharp turns or sudden speed changes — Sharp turns can tear the mat and decelerating/accelerating quickly can rip/tear the mat or leave indentations.

ust when we thought we were out of the weeds, here comes another virus variant (omicron) to stir the pot once more, giving us another major issue to deal with as we enter 2022. Just what we needed! Unfortunately, the equipment situation is still a mess, as well. There is significant demand but a lack of both new and used units. New unit prices are up 20+% and used units are up 30+%, causing a lot of pent-up demand and deferral of equipment purchases. In short, contractors are deciding to keep their current internal fleets longer, hoping that required parts will be available as needed. As part of my homework to keep up to date on the industry, I reviewed two major industry reports prepared by Deloitte (CPS firm) and Equipment Watch. The major points I gathered were: ˜ Equipment costs will remain above average for some time to come. So, if you need equipment for your 2022 schedule, be prepared to have to deal with used or rental units. ˜ Technology and related productivity increases will allow companies that embrace it to lower time and costs on jobs, which will become reflected in their bid pricing sooner rather than later. Another point I noted in the reports is that equipment costs now represent up to 30% of job costs. When I was CFO at the Associated Equipment Distributors, it was running at about 17%. Thinking about it, this could mean: ˜ equipment costs are higher; ˜ more equipment for specific uses is available today compared to 10 to 15 years ago; ˜ or contractors are finding ways to cut costs and improve productivity using the current crop of equipment available to them. The answer is probably a combination of the three.
PLAN FOR PRODUCTIVITY In planning for 2022, I would advise you do a quick inventory of what you have and develop a unit by unit list of maintenance required now or sometime during the year. As part of this process, you may want to nail down your parts suppliers and purchase any hard to find parts if they are available. In addition, I would schedule
50 EQU IPMEN T TOD AY | January 2022
any outside work ASAP to determine whether the dealer or rental company can make your units ready before your construction season starts. On the productivity front, if you want to stay competitive and profitable, you should examine your people, processes and technology to determine if they will provide adequate productivity to remain competitive compared to contractors that have chosen to upgrade their systems to cut the costs and time required to complete a job. The important thing about productivity is it is basically “free” if you can use your existing staff to get work completed with fewer hours compared to what they did in the past (same people and material costs converted into a completed project in less time). Believe me, this is where the industry is heading, meaning changes are required to improve productivity. I can promise that you will have a problem if you are doing things the same way you did seven to 10 years ago. One area where a lot of contractors are suffering is finding adequate workers. Guess what? There are costeffective technology platforms focused on recruiting blue-collar workers that can help. I suggest investigating these platforms then arranging a demo. (Links to several options can be found at www. ForConstructionPros.com/21940892.)
PREPARE FOR INFLATION-RELATED COST INCREASES The last topic we need to cover is inflation. It is here and it is going be around for some time. Contractors will feel it in material, labor and interest costs. Consequently, it may be prudent to consider converting any floating rate borrowing into a fixed rate note while rates are still low. Last I heard, they are expecting at least two rate increases during 2022. With inflation raising your costs, your bidding has to take these higher costs into account, which I’m sure it will. But even if it does, you have to manage your margins on a real-time basis to ensure they will provide gross profit dollars in line with your historical gross profit margins. You do not want to find yourself in a position where you bid based on where you thought your costs would end up and then find out the margin dollars are well below where they should be. In 2022, where costs could materially change throughout the year, you have to know on a daily basis how the “real” cost compares against budget. See what your system can do to provide this information. Before we close, one quick follow-up: the Employee Retention Credit referred to in a previous column (www.ForConstructionPros. com/21722627) will not be available for Q4 of 2021 unless you are a new company. It’s still available for Q1, Q2 and Q3 if you qualify. Now, let’s hope that the pandemic is behind us and all of you can get booked up for the entire year. But even if that is the case, material, payroll and funding costs need to be monitored closely. Make a lot of money in 2022!
