Facing construction industry COVID challenges
anada’s construction industry continues to face tough times when it comes to the effects of COVID-19 and the ongoing lockdown across the country. The need for infrastructure and residential construction to continue has often been challenged by the needs to reduce the spread of the novel coronavirus in our communities. As the country has continued the fight to flatten the curve, construction has continued – in one way or another. Different provinces have taken different approaches to the construction industry, but for many contractors work has continued, though perhaps things have been slower than before the pandemic came into full effect. Now, as movement is being made toward cautiously reopening the economy in the country’s largest provinces, stakeholders and associations representing the construction industry are trying to ensure that workers remain safe on the job while also encouraging governments of all levels to provide supports to the companies that keep this industry – and Canada – growing. Ontario has been one of the more active provinces in terms of regulations for the construction industry; the province released a list of essential projects early on, and has made adjustments over time to add and remove different types of work to that list. According to the Canadian Construction Association, about 50 percent of the industry in Ontario was shut down because that work involved private land development. The province’s move to reopen some of that work is being applauded by the CCA and the industry in general, as it brings some balance to the sector that saw contractors able to work on municipal projects but not private jobs that were virtually the same in terms of what needed to be done. As of early May, Ontario released a new list of project types that would be allowed to continue, including “site preparation, excavation and servicing for institutional, commercial, industrial and residential development.” That is an important step for many projects – without excavation and site preparation, there’s not much more that can be done, so having those types of contracts underway provides a launching point for building construction to start more easily down the road. In Quebec, which is still grappling with a growing COVID-19 case load, all sectors of construction have been set to reopen in early May. Like Ontario, the province has provided employers with a guide for construction site safety, as well as advisory material for employees, and is encouraging staff to keep common-sense measures for preventing the spread of disease in mind as they work alongside their teammates. Other provinces that did not take the same drastic steps as Ontario and Quebec have continued to work and focused on mitigation efforts to keep their construction employees safe. Those contractors and associations are watching Ontario and Quebec carefully as they slowly reopen. These are first steps, but they’re big ones that will help those contractors whose work has been constrained or stalled for the last few months get back on the job and get the money flowing again. The next moves will depend on governments, who are being lobbied by the CCA and others to ensure that construction is at the top of the list for financial backing and support while the economy recovers. There will be other challenges as well, as supply chains are re-established and the new normal of safety is fully established. With a team effort from government, associations, employers and workers on the ground, our industry will hopefully be able to get back to work safely – and sooner rather than later. Heavy Equipment Guide will continue to cover the effects of COVID-19 on the heavy construction sector both in upcoming issues and online.

Enduron dewatering screens reliably separate product with a high degree of efficiency, while robust Isogate knife gate valves contribute to easy maintenance.
The new vehicles are designed with an all-new chassis that gives operators additional comfort, strength and performance for the job. The chassis design improves ground clearance and off-road capability while allowing more range of motion in the suspension for superior ride quality – further enhanced with added seat contours that are designed for maximum comfort.
FOCUS ON COVID-19 Demand drops, supply chains in trouble, equipment manufacturers report
MANUFACTURERS SUPPORT HEALTH CARE WORKERS WORLDWIDE As the COVID-19 pandemic continues to slow the global economy, vehicle and heavy equipment manufacturers have thrown their considerable capabilities behind the health care sector, moving factories and personnel into producing protective gear and equipment needed as part of life-saving efforts around the world. FORD TEAMS WITH 3M ON NEW PAPR Instead of building vehicles, Ford has begun producing a variety of protective items, while also pairing its expertise with others to produce even more important medical products to help fight the coronavirus. The company started out with a plan to produce more than 3 million face shields in its Plymouth, Michigan, factory, and then connected with 3M to design and begin production of a new powered air-purifying respirator (PAPR). In addition, Ford is working to produce reusable gowns using airbag material, and has teamed with Thermo Scientific to help produce equipment for COVID-19 collection kits. JCB SHIFTS FROM CABS TO VENTILATORS The U.K. has been hit hard by the pandemic, and JCB has stepped up to help reduce a gap in the country’s ventilator supply. A direct appeal from Prime Minister Boris Johnson led to JCB restarting production at its Cab Systems factory to provide housings for newly designed ventilators. The company is expected to build a minimum of 10,000 housings for a brand-new design of ventilators developed by Dyson. About 50 employees will be part of the effort. GENIE PRODUCES PPE FOR REGIONAL FIRST RESPONDERS AND HOSPITALS Genie’s facilities in Redmond, Washington are hoping to reduce the gap in personal protective equipment in its region by developing a concept that would help meet needs at local hospitals. The effort began with a face shield design developed by Jim Donaldson, Genie Engineering Design Manager, Terex AWP. Donaldson explained: “After watching a video about the types of medical equipment our hospitals needed, I thought we would be able to make the face shields that go over the N95 masks. I went to the store and bought a sponge, bungee cord and a poster that came packaged in a plastic tube. I cut up the tube to make the shield, and then I attached the sponges and bungee cord.” The team was expected to start with 4,000 to 5,000 shields, and potentially more depending on material availability and need. VOLVO STEPS UP LOCAL SUPPORT IN PENNSYLVANIA Local support is the theme of Volvo Construction Equipment’s efforts as well, with the company providing face shields and ear guards to local health care providers near its Shippensburg, Pennsylvania, headquarters, part of the Volvo Group’s work in providing financial aid, medical supplies, expertise and donations across Canada and the United States. The face shield uses material from fabrication grinding shields fitted to 3D-printed visor brackets; Volvo then uses foam rolls from its cab assembly line to pad the shield visors. Ear guards are also being produced using 3D printers. DEERE AIMS FOR MORE THAN 200,000 FACE SHIELDS John Deere’s Moline, Illinois, Seeding Group plant has plans to produce 25,000 face shields – and potentially 200,000 more – in partnership with government agencies and the United Auto Workers. The company is using an open-source design from the University of Wisconsin–Madison for the project, and is leveraging its employees’ skill, innovation and expertise to complete the project. Deere is also producing face shields for its factory employees and donating PPE to health care facilities, as well as launching an innovations site to share open-source specifications for projects related to the COVID-19 fight.
Nine out of ten U.S. equipment manufacturers say the COVID-19 pandemic has had a very negative impact on the economy while more than half believe it has had a very negative impact on the industry overall, according to results of a survey released by the Association of Equipment Manufacturers (AEM). In addition, eight out of ten executives say the federal government should prioritize a significant investment in the nation’s infrastructure to help equipment manufacturers weather the crisis and help rebuild the economy. The survey, conducted April 16–27, drew 105 responses. Key findings include: Nine out of ten executives surveyed said that the impact of the COVID-19 pandemic on the overall economy is very negative, while more than half said that the impact on the industry is equally bad. Seven out of ten executives surveyed have experienced a moderately negative impact on their supply chain, while a quarter said the impact has been very negative. Four of ten executives surveyed expect the outlook for the next 30 days to get worse and said they plan to lower their financial outlook for the same period of time by more than 30 percent. The outlook for the rest of the year is better, but six out of ten said they still plan to reduce their financial outlook by up to 30 percent. Nine out of ten executives surveyed cited a decline in demand for equipment as the primary impact of the COVID-19 pandemic on their business.
Construction industry puts worker safety and well-being at the forefront: CCA The health, safety and well-being of workers, their families and friends, and the communities we operate in is always the top priority of the Canadian Construction Association (CCA) and its more than 20,000 member firms. This has never been truer than it is right now. From the construction and renovation of hospitals, to keeping roads safe, to bringing power and clean water to homes, the construction sector builds communities and delivers projects that are essential to Canadians’ quality of life and to the success of our country. The CCA and its provincial and municipal counterparts have been very active in monitoring the guidance and direction of public health and government authorities, and providing its members with ongoing information, resources and support to put in place stringent measures to protect their employees and help flatten the curve. These measures are extensive and include employee monitoring, new safety and hygiene procedures and checklists, social distancing, sanitizing stations, frequent sanitization of sites and reduced personnel on sites. The CCA’s position is that compliant sites should be open and those that cannot consistently comply with measures and guidelines of public health authorities should shut down.
Trucking industry under strain from COVID-19 – federal relief needed While public support and appreciation for truck drivers during the COVID-19 crisis remains high, a recent survey by the Canadian Trucking Alliance shows that federal aid is now required to provide needed relief to trucking companies whose operations have been severely strained by the impact of the pandemic. The Government of Canada has introduced several financial measures to assist Canadians and businesses generally suffering financial hardship as a result of this pandemic, but the trucking industry needs more assistance. To ensure security and stability in the supply chain, CTA is asking the Government of Canada to introduce a Payroll Tax Deferral Program, providing fleets the needed cash to maintain operations. Additionally, CTA wants an increase in the meal allowance for all truck drivers facing rising costs associated with operating during COVID-19. A recent CTA survey drew nearly 100 responses, with key results showing that carriers have seen a 27 percent drop in revenue and 300 percent increase in “empty miles” where trucks are not generating revenue. Without improvement, 37 percent of fleets have significant concerns regarding continuation of their operations. Sixty-three percent of fleets said their customers are asking for payment deferrals or simply have not paid the company for services. MAY 2020

IN-DEPTH REPORT: COMPACT TRACK LOADERS
REIMAGINING TRACK LOADER
THE COMPACT By Kaitlyn Till, Editor in Chief
he compact track loader is a highly versatile, productive machine that fills many roles on the jobsite. When a contractor needs to clear brush, finish grade, work on landscaping, remove snow or load a truck, a CTL with the right hydraulic capability and attachments can do all these jobs – and more. The largest CTLs can even compete with small dozers and wheel loaders but offer better flexibility and easier trailering. All of these advantages have factored into the CTL’s significant growth in popularity. Now, manufacturers are pushing the potential of the CTL even further, reimagining its design and capability.
Case pushes CTL potential
At CONEXPO-CON/AGG 2017, Case Construction Equipment unveiled a novel new concept: a compact track loader/small dozer hybrid dubbed “Project Minotaur.” This compact dozer loader is designed for precise pushing power. It has the footprint of a compact track loader with a dozer blade, making this machine ideal for both grading and loading applications. After hundreds of hours of testing prototypes with operators, Case unveiled the production-ready version of Project Minotaur at CONEXPO-CON/AGG 2020 – the DL550B compact dozer loader. On this two-in-one machine, the six-way dozer blade and C-frame attach directly to the chassis and primary coupler. When the operator needs CTL operation, they hydraulically detach the C-frame and blade and attach a bucket or other CTL attachment. On a standard CTL with blade attachment, the stress is channelled though the coupler and arms of the loader. Case says that this compact dozer loader design channels that power and stress through the chassis and offers more stability and smoother operation. It features a vertical lift geometry; a fully integrated ripper option is available, and the dozer-style undercarriage is available in steel or rubber track configuration. George MacIntyre, product manager for compact equipment at Case, said that “a standard CTL with a dozer blade attachment can be effective for occasional work, but that combination doesn’t provide true six-way blade performance or the long-term precision possible with the DL550B. “This design is much better for strength and reliability as the pushing power is channelled through the entire machine. We have also integrated dozer controls for a much more intuitive experience for the operator versus the complicated control arrangement that comes with a common attachment blade.”

IN-DEPTH REPORT: COMPACT TRACK LOADERS
CASE DL550B The compact dozer loader weighs 18,000 pounds and has a 114-hp engine. It is also designed for use with high-power attachments, such as mulchers. Optional auxiliary hydraulics offer up to 40 gpm at 4,100 psi. Case dealers can outfit the DL550B with Topcon, Trimble or Leica machine control technology and the compact dozer loader is compatible with Case SiteControl CoPilot which provides basic slope/grade control.
JCB reinvents the CTL to reach farther, lift higher and dig deeper
CTLs have held their own in comparison with small wheel loaders and dozers in many applications for years, but with the Teleskid, JCB set its sights on adding another capability to the already versatile CTL platform: long reach provided via the telescoping boom of a compact telehandler. JCB’s first Teleskid was introduced at CONEXPO-CON/AGG 2017. This innovation, totally unique to the market, combines the chassis of a compact track loader or skid-steer loader with the telescoping boom of a compact telehandler. The design combines vertical and radial lift capability; a bucket-positioning levelling system allows the bucket level to be set and maintained throughout the boom’s range of movement. JCB’s CTLs were already designed for side entry with a single arm boom, making them the ideal platform to evolve into this new design. The company now offers three Teleskid models: the large-platform wheeled and tracked versions introduced in 2017 and a small-platform tracked model introduced in 2020. On introduction of the newest model, Keith 14
HEAVY EQUIPMENT GUIDE
>> MAY 2020
Hoskins, vice president for compact products, noted that JCB Teleskids are the best-selling skid steers and compact track loaders in the company’s 75-year history. The Teleskid design enables the machine to reach farther, lift higher and dig deeper than other similarly sized compact track loaders. The smallframe tracked model, the 2TS-7T, has a rated operating capacity of 2,096 pounds. It achieves lift height of 11 feet 10 inches, forward reach of 7 feet and dig depth of 2 feet. The larger tracked 3TS-8T, with an ROC of 3,695 pounds, offers 13 feet 3 inches of lift height, 8 feet of forward reach and 3 feet of dig depth. Both machines are compatible with a range of CTL attachments and high-flow hydraulics options are available.
Technology helps operators do more with greater efficiency
Technology advancements are making compact track loaders more versatile than ever. In 2019, Bobcat introduced the first model in a fully revamped lineup of its CTLs and previewed technology options that will make operation safer and more efficient. Bobcat is introducing a new subscription service for R-Series loaders called Features On Demand. With this unique service, customers can purchase a compact loader with hardware for all advanced features pre-installed on the machine. After purchase, the customer can select which features to turn on through the subscription service; users can then adapt the equipment to suit their needs as they change – only paying for premium features as they are needed.
Features On Demand include: high-flow auxiliary hydraulics, 2-Speed travel, reversing fan, dual-direction bucket positioning and automatic ride control. Bobcat says that Features On Demand will enable customers to lower their upfront cost when purchasing a new machine if they don’t need to use all of the advanced features right away. Bobcat’s new MaxControl turns the operator’s smartphone into a remote controller for the M2-Series or the new R-Series compact loaders. Via an app, the operator can use a smartphone to control machine functions and operate attachments from up to 300 feet away. Bobcat says this feature is ideal for one-person jobs where the operator may need to get in and out of the cab frequently. By eliminating the need to repeatedly enter and exit the machine, MaxControl reduces risk of falls. Integrated machine control technology is no longer found exclusively on larger equipment. At CONEXPO-CON/AGG 2020, Deere unveiled the industry’s first compact track loader with integrated grade control. The 333G SmartGrade compact track loader completes grading tasks faster and with less rework than a machine without grading technology. John Deere says that this machine is also more versatile and easily transportable as there are no masts and cables. Ideal applications for this model include roadbuilding, site development and landscaping. Gregg Zupancic, product marketing manager for skid steers and compact track loaders, noted, “Integrating our innovative SmartGrade technology into the 333G compact track loader provides our customers with a solution that is transportable, can fit into tighter spaces and will ultimately reduce labour costs.”
John Deere also launched its DozerMode control solution on this model. When the operator switches to DozerMode, the EH joystick control system functions like a crawler dozer. The company says that this functionality is beneficial when operating the CTL equipped with its six-way dozer blade attachment for cutting a grade or spreading materials. Emphasis on meeting the needs of a variety of applications was also Caterpillar’s focus with the launch of the D3 Series compact loaders in 2019. These machines are the first Caterpillar compact loaders to support the company’s new Smart Attachments system. With this technology, the carrier recognizes certain attachments and tailors the controls to the task. Cat is offering a range of Smart Attachments designed for this capability, including a backhoe attachment, grader blade and dozer blade. Cat is offering advanced control features for repetitive tasks, including Return-toDig and Work Tool Positioner, along with dual-direction self-level.
What’s next for the CTL?
The focus on battery-powered equipment has been concentrated on the excavator – that is set to change. At CONEXPO-CON/AGG 2020, Bobcat previewed the next frontier of CTLs – electrification. The T76e concept loader offers emissions-free, fully electronic operation provided by components from both Moog and Green Machine. 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 and notes that this concept will change compact equipment in a number of ways, from improved productivity and enhanced precision, to more intelligent machines that bring new capabilities to the jobsite.
JOHN DEERE SMARTGRADE 333G
The latest CTL introductions and updates
Bobcat’s R-Series compact loaders have received the largest redesign of a core product in the company’s history. In addition to technology options, Bobcat has focused on strength in this redesign. Cast steel sections in the arms give these loaders greater strength while reducing the profile for better visibility; the cast steel Bob-Tach mounting system provides a stronger connection point and is designed to allow dirt and debris to pass through, more easily reducing buildup. The first CTL model in the series is the T76 with more models to come. In 2019 John Deere upgraded its small-frame G-Series loaders. Focus was on improving cab comfort and features. John Deere has introduced new Bluetooth connectivity and redesigned the manual controls for operator comfort and a rearview camera is now an option. Additional updates include protected auxiliary

hydraulic lines that run within the boom, optional support for two sets of counterweights and an integrated four-point tie-down system. More control, more visibility and more operational insight are the hallmarks of Case’s B Series, which was introduced at World of Concrete 2020. Immediately noticeable upon entering the cab of the B Series is the 8-inch touchscreen. This unique command centre, standard on all B Series electro-hydraulic models, provides the operator with split-screen display which simultaneously shows the operator machine data and the view from the backup camera, which is also standard on electro-hydraulic models. The operator’s experience is also the focus of the two 100-hp CTLs that Wacker Neuson introduced at CONEXPO-CON/AGG 2020: the radial lift ST40 and the vertical lift ST50. The company is focusing on key points of accessibility on its new machines, including easier entry to and exit from the cab, more room for the operator in the cab, and more accessible maintenance points. In 2019, Kubota unveiled its lightest and most maneuverable compact track loader ever. With the introduction of SVL65-2, Kubota says it focused on offering big power in a small package. The 68-hp model has a rated operating capacity of 2,100 pounds at a 35 percent lift or 3,000 pounds at a 50 percent lift, a reach of 88.65 cm, and a hinge pin height of 301 cm. Self-levelling is standard and all major machine and attachment functions are controlled via the multi-function levers. The Advanced Multifunction Valve makes simultaneous operations run smoothly. Providing power in a compact package was also Gehl’s focus when it introduced the RT153 CTL. At 35 percent operating capacity, the model can lift 1,350 pounds. The operating weight of 6,510 pounds makes it easy to transport and Gehl says that this model is ideal for the rental market. Takeuchi previewed a new CTL at CONEXPO-CON/AGG. The radial lift TL8R2 has a rated operating capacity of 2,116 pounds at 35 percent of tipping load and a 73-hp Kubota engine. It will be available in late 2020. With the introduction of the D3 Series CTLs, Caterpillar focused on changes to the undercarriage frame and torsion axles to improve stability while travelling with heavy loads and during grading and truck loading. Two-speed travel is standard. The Land Management version of Cat’s highest-performance model, the 299D3 XE, comes straight from the factory ready to tackle tough brush. This 110-hp CTL with 40-gpm auxiliary hydraulics is outfitted with additional seals, covers and guarding components. The 80 percent larger fuel tank ensures long operating hours between refuelling.

REVOLUTIONARY CAB FOCUS OF DOZER DESIGN
LiuGong Dressta’s new TD-16N dozer is the result of a seven-year design process focused on improving operator visibility and safety By Lee Toop, Editor
“As the operator interface has changed and safety requirements have rightly improved, the cab has become the most important aspect in designing any new product.” Gary Major, director of industrial design, LiuGong Dressta
HEAVY EQUIPMENT GUIDE
>> MAY 2020
onstruction equipment is often designed for power and strength, ensuring the machine can handle the rigours of its task on the jobsite – digging, pushing, lifting and so forth. At the centre of that machine, however, is the one key part that makes all of that happen: the operator. With today’s labour challenges driven by an aging workforce and other factors, manufacturers are giving contractors tools to help attract good equipment operators, and cab design has become an area that many companies have focused on. The more comfortable and safe a cab is, the more likely it is that operators will stick around to use that machine for its owner. One feature that is often a challenge for designers is visibility. Construction equipment is hardly streamlined or aerodynamic; the bulk from counterweights, big engines and other aspects that make it possible for a machine to do its job are difficult to design around. At the same time, making it easier to see the area around the machine immediately improves safety for the operator and everyone on the ground.
Operator’s needs are the design starting point
When track dozer specialist Dressta set out to design the newest machine in its range, the TD-16N, the cab was, in many ways, job one. The team behind this new dozer wanted to revolutionize the operator’s ability to see the jobsite around them. “In the past, and I’m including my 32 years in construction equipment, the cab enclosure had been little more than a means of keeping the operator dry in the rain and cool in the sun – it was basically a shelter,” described Gary Major, director of industrial design with LiuGong Dressta. “As the operator interface has changed and safety requirements have rightly improved, the cab has become the most important aspect in designing any new product.” Older machine designs didn’t take the operator’s needs into consideration, noted Edward Wagner, LiuGong executive director of new technology. “You don’t have to look too far back in time to find heavy construction equipment was designed to optimize the machine for simplicity and low cost with little to no regard for the actual operator. Anyone who has spent a 12hour day running a machine with an
open cab, or no cab at all, can understand this – the old machine would literally beat up the operators,” Wagner said. “Finally, owners began to realize there was a cost advantage to having the operator stay comfortable and productive throughout the day.” Even with that in mind, many machines are still designed based on the needs of the machine layout and without a lot of thought given to how that design affects the operator. “We flipped this with the design of the TD-16N, as we literally started with the operator and their needs, and built the machine around them,” Wagner noted. Dressta determined that it was time to consider updates to its dozer line, and approached the TD-16N as a starting point for that process, Wagner said. “The legacy machines needed enough updates that it actually was a simpler and faster route to make a clean sheet design for this large hydrostatic dozer.” Major said the ground-up approach to the new machine meant the design team had a lot of freedom to meet their goals. “The TD-16N is a ground-up new concept, propelled by one primary goal – to build a bulldozer with unrivalled
levels of visibility, safety and comfort,” he said. “This, of course, meant a total rethink of traditional dozer packaging and the cab was an intrinsic part of that focus – you need to take a holistic view of the machine, as opposed to looking at individual components.”
Design on the TD-16N started in 2013 and spent two years as a “black” project with just a few people privy to the process before the engineering team was brought on, Major said. The first steps focused on what Wagner described as a “pyramid of principles” that guided the team's approach. The operating needs of the machine – the blade and track size and orientation – were the base of the pyramid, but the centre was the customer, defined as the owner, operator and mechanic who will own and run the machine, Wagner said. “We literally optimized the location of the operator with respect to the blade and tracks, and only then did we start the design of the rest of the dozer around those needs,” he explained. There was some pushback when the design process started, mostly thanks to fear of the unknown, Wagner noted. Some suggested that the
team would be better off building a more traditional machine, but as the project advanced, those attitudes began to change. “Once we had the basic layouts finished, many peoples’ fears subsided. After our first prototype was built and people could see it really was going to work, the team gained momentum and confidence,” Wagner said. While innovation was the biggest driver of the process that led to the new machine, it was paralleled by LiuGong Dressta’s overarching principles as well, Wagner noted. “The tip of the pyramid is our own company needs, such as maneuverability. Consistent with our design philosophies, we proved yet again that a machine designed to be easy to service and repair is also quite easy to assemble in the factory.”
Striking new dozer design
The result of this process is an entirely new dozer that provides what Dressta states is unparalleled visibility for the operator. The new cab design is striking in the size of the windows that wrap fully around the operator station; from the seat, the design of the machine body takes advantage of all that window space to allow the operator to
see 309 degrees around the machine. Steep angles on the front of the machine and no obstacles elsewhere make the visibility excellent all around. “In order to meet our aspiration for operator visibility, the DLO (daylight opening – a frequently used automotive term) ratio is much greater than any other cab on the market, something emphasized by our choice in using flat glass throughout,” he said. “The decision to use a planar glass laminate was primarily for optical quality (for example, zero distortion) with ease of replacement second.” Flat glazing also helped enhance the overall aesthetic of the machine, he added. All of that glass did bring some unique concerns to the table, however: added thermal loading. “Addressing this task has been done in collaboration with industry-renowned HVAC specialists; plus, we have topped the cab with a roof moulding painted in light-reflecting silver, a surprisingly effective detail,” Major said. The TD-16N, introduced at CONEXPO 2020, has a strikingly unique design in a machine that can handle operator needs on the jobsite. It features an automatic dual-path hydro-
static drivetrain and standard six-way angle blade; compatible with 2D and 3D grade control systems, the machine generates 170 hp and has an operating weight of 19,090 kg or 42,090 pounds.
New access point concepts
Carrying on the desire for improved safety, the machine also features access points that mean the operator never has to climb onto the tracks to get in to the cab. Plus, all daily check and maintenance access points are reachable from ground level. The results of the seven-year design project generated plenty of discussion at CONEXPO, Wagner noted. “Some of the key customer concerns I heard were: ‘Finally, a dozer designed by someone who operates dozers,’ ‘I can’t believe how much I can see; this will make my work both faster and more precise;’ ‘why didn’t anyone do this before?’” he said. Dressta chairman Howard Dale said the TD-16N will benefit in improved safety and productivity for owners. “The superior visibility of this machine will certainly help operators be more productive and do a better job in less time,” he said. “We also know that this machine will make the worksite safer for everyone.” HEG
Dressta’s new cab design shapes the machine and structure to give ideal angles to the ground on all sides of the dozer.

WORLD’S FIRST FULLY ELECTRIC BACKHOE LOADER Case invests in new propulsion technologies for earthmoving equipment By Kaitlyn Till, Editor in Chief
T “The backhoe loader is perfectly suited to electrification.” Eric Zieser
HEAVY EQUIPMENT GUIDE
>> MAY 2020
he 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. That was the message delivered by Hubertus Mühlhäuser, (now former) chief executive officer of CNH Industrial, at CONEXPO-CON/AGG 2020. With its partners, Case Construction Equipment is developing new propulsion technologies as it anticipates this future. At bauma 2019, Case revealed ProjectTETRA, a methane-powered concept wheel loader developed with FPT Industrial, the powertrain technology division of CNH Industrial. CNH Industrial has also made significant investments in Nikola Motors, a developer of hydrogen-fuelled and battery-electric trucks. Now Case has introduced its first production-ready fully electric machine: the 580EV backhoe loader. Originally named “Project Zeus,” the 580EV is the world’s first fully electric backhoe loader and was quietly demoed to large crowds indoors at CONEXPO. “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. “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.” The 580EV is powered by a 480volt lithium-ion battery pack. It can charge with a 220-volt connection and will run for most eight-hour workdays. Case partnered with Green Machine and Moog on the electrification and tested the machine with utility companies on the east coast of the U.S. The first two models have been sold to utility companies. “The Case 580EV is equal in breakout force to diesel-powered backhoes in the Case product line,” noted Leandro Lecheta, head of Case Construction Equipment North America. “It provides lower daily operating costs while also producing zero emissions. This allows it to work in tight spaces and enclosed working conditions.” But what’s the value proposition? Contractors expect new technology to come with a high price tag and
the 580EV is no different. Case has run the numbers and expects that the average fleet will see a payback on that premium price tag within five years. It is estimated that the 580EV will save fleets up to 90 percent in annual vehicle service and maintenance costs with the eliminated diesel, engine oil, DEF, and associated engine maintenance and labour costs. The 580EV can also open up contractors to new business opportunities where low or no emissions is a requirement. “The real standout of this machine is the long-term environmental and financial sustainability that it provides its owners,” Lecheta added. The Case 580EV development was driven both by customer request and CHN Industrial’s own development of alternate propulsion technologies. Zieser noted that Project Zeus is just the start. Case continues to work with its partners Green Machine and Moog, and in the next phase of development the company will continue to advance the technology along with FPT Industrial and Nikola Motors. “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 propulsion into other product lines and markets that will also see the benefits from these advances related to sustainability and performance.” HEG
PAIR OF WHEELED EXCAVATORS FEATURE MULTIPLE DESIGN IMPROVEMENTS Two new Cat Next Generation wheeled excavators – the Cat M314 and M318 – feature multiple design updates that boost machine efficiency and lower long-term operating costs. Advanced hydraulics more efficiently power attachments, including Cat tiltrotators to increase machine flexibility at the jobsite. Both Next Gen wheeled excavators are powered by the fuel-efficient Cat C4.4 engine that now meets stringent EU Stage V, U.S. EPA Tier 4 Final, and Korea Tier 4 Final emission standards. The two models deliver high power, while offering up to 5 percent improved fuel economy. A larger fuel tank on the M314 provides extended work time between fuel refills. From dirt to asphalt, these versatile excavators are built to quickly tackle a wide range of projects. Featuring up to 15 percent more swing torque over the F Series, the M314 and M318 allow operators to quickly complete the task and move onto the next. With travel speeds in excess of 34 km/h (21 mph), they are fast and efficient moving from job to job. The M314 and M318 come standard with the new, larger Next Gen operator’s cab that offers improved entry/ exit and boosts comfort and productivity. A low-profile engine hood design, large front, rear and side windows, and small cab pillars offer improved visibility into the trench and around the machine. Standard rearview and sideview cameras further improve visibility. Advanced viscous mounts reduce cab vibrations which cuts down on operator fatigue, while easy-to-reach controls help increase operating comfort.
crease machine servicing efficiency. With new Remote Troubleshoot, dealer technicians remotely run diagnostics testing without impacting machine productivity to detect potential issues by analyzing real-time machine data captured by Product Link. Remote Flash works around the company’s production schedule and conveniently assures these new excavators are operating with the most current
version of on-board software. Longer lasting filters on the Cat M314 and M318 Next Gen wheeled excavators deliver up to a 10 percent savings in maintenance parts. The new hydraulic oil filter delivers improved filtration and a 50 percent longer change interval at 3,000 operating hours for reduced maintenance. Diesel fuel purity is better protected through the machines’ new two-level fuel fil-
tration. Filter life and maintenance intervals are now conveniently tracked on the in-cab touchscreen monitor, so machine uptime is maximized. Service technicians can quickly check all daily maintenance checkpoints, including engine oil, from ground level. Cat S∙O∙SSM ports are also conveniently accessed from ground level for sample fluid extraction, simplifying maintenance.
Deluxe or premium cab designs
Customers have the choice of either deluxe or premium cab designs. The deluxe cab features a seat that is heated and air-adjustable, while the premium seat is heated and cooled, plus it adjusts automatically. Ample storage beneath and behind the seat, in overhead compartments and consoles give operators plenty to room to stow gear. The excavators are started using the in-cab push-button or remotely via a Bluetooth key fob, or the unique Operator I.D. function. The large, 240-mm (10-in) touchscreen monitor and jog-dial control offer flexible, ease-to-use navigation of the machine controls. Operators can program power mode and joystick configuration to their preferences, so the excavator remembers each operator’s settings on start-up. Auto axle lock detects when the service brake must be locked or unlocked. The new excavators build on the standard Product Link technology that provides machine location, hours, fuel usage, idle time, diagnostics codes and other machine data. New remote diagnostics tools help save service trips to the jobsite to in-

GRADE CONTROL PLATFORM UPDATE BRINGS GROUNDBREAKING FEATURES FOR ALL MACHINE TYPES Trimble has released a new version of its Earthworks grade control platform
rimble has released its Earthworks Grade Control Platform version 2.0 with groundbreaking new features for all machine types, along with the release of the Trimble Earthworks Assistant App for in-cab learning material. These improvements are designed to enable faster ROI, increase productivity and decrease training time for operators. A first in the construction industry, according to Trimble, Horizontal Steering Control for dozers automatically controls the machine to follow any horizontal alignment such as a back of a curb, breakline, roadway centreline or bottom of slope, without operator assistance. Another first, Augmented Reality for excavators enables users to easily understand 3D models, cut/fill information, slope data and other bench points and reference points on the in-cab display in context, without the need to interpret complex 2D plans or stakes. A new mastless motor grader configuration gives operators an improved range of blade motion, allowing for machine control in applications where it was previously not possible. Integrated Trimble LOADRITE Payload Management displays grade control and accurate payload data on one screen, increasing mass haul productivity and efficiency by preventing underloading, and improving safety by avoiding overloading. Contractors can maximize their investment in Trimble Earthworks by leveraging the versatility of these added options. Trimble Earthworks is also now available for compact grading attachments with dual GNSS, single GNSS and total station guidance options.
Operators can focus on grade and productivity
Horizontal Steering Control allows the operator to focus on the grade and machine productivity rather than worrying about steering, reducing operator fatigue and errors. It enables the machine to follow the horizontal guidance from the 3D model, providing operators increased awareness of their surroundings, better accuracy and improved productivity with de22

creased overlap and fewer passes. “Trimble is on the forefront of innovation and cutting-edge technology along the path to automation,” said Scott Crozier, vice president, Trimble’s Civil Engineering and Construction. “Using proven steering technology from Trimble Agriculture, we are continuing to advance construction machine control yet again.”
Mastless configuration for motor graders
Trimble Earthworks for motor graders mastless configuration mounts one GNSS receiver on the cab and one on the gooseneck of the machine to eliminate masts and cables traditionally located on the blade. Mastless GNSS receivers are ideal for the blade's maximum range of motion, which is needed for steep slope work and complex designs with tight tolerances. The new configuration enables contractors to decrease risk of damage to the machine, keep valuable receivers safer as well as reduce the time needed to remove and reinstall them each day.
Excavators get AR system
Augmented reality was first released in the Trimble SiteVision system and is now available on excavators with Trimble Earthworks. Using a camera mounted on the outside of the machine, operators can view 3D models in a real-world environment at a true-life scale, in the context of existing surroundings. On the Trimble Earthworks display, the model is overlaid onto the existing ground giving the operator a better understanding of the work that needs to be done. Visibility of the bucket gives operators better situational awareness to be able to keep surrounding people and objects safe. “With the intersection of physical and digital worlds, Trimble is empowering contractors to accelerate their business,” said Cameron Clark, business area manager, Trimble’s Civil Engineering and Construction. “Augmented reality simplifies complex concepts by allowing users to see a blend of digital content and real-world environments.”
Earthworks 2.0 includes mastless configuration for motor graders, offering a greater range of blade motion (top). Augmented reality is now available for excavators (above). Earthworks Assistant app added
Trimble now has an easier way to access critical Earthworks learning material and documentation, allowing for a shorter learning curve and less downtime for operators. This stand-alone app consolidates and simplifies access to training guides and videos inside and outside of the cab. The Earthworks Assistant App makes it easy to learn and troubleshoot using an Android cellphone, even from remote sites.
PILING, DRILLING & FOUNDATIONS
PILE SWAP AND CUSTOM TOOLING SAVES MONEY FOR CONTRACTOR Challenging contract calls for shift in piling type and support from Bauer rigs By Brian M. Fraley
inde-Griffith Construction Company was called on to assist when the original contractor on a condo project was unable to reach bearing capacity on a test pile program. The end result was a cost-saving switch to Full Displacement Piles (FDP) using a Bauer BG 36 H Drilling Rig and custom tooling. Linde-Griffith – founded in 1909 – was primarily a pile driving contractor until about 20 years ago when it expanded into foundation drilling. “We’ve seen more and more engineers seeking techniques that offer greater capacity with less noise and vibration,” says Linde-Griffith’s Senior Executive Vice President Mike Shannon. In the midst of apartment buildings and businesses, the yellow mast of a Bauer BG 36 H Drilling Rig towered more than 90 feet over the landscape. The Linde-Griffith field crew braved 30-plus-mph winds and single-digit windchills as the linchpin machine of its FDP operation bored through the frosty soil. The Hackensack project started out as a driven pile project. The previous contractor had run a Pile Driving Analyzer (PDA) Test and was unable to reach the design capacity despite installing various pile types to depths of up to 175 feet. The owner and engineer reached out to Linde-Griffith’s John Shannon looking for ideas. Linde-Griffith suggested using FDP piles. Mike Shannon summarizes the FDP technique: “The piles don’t rest on rock here, you get your load bearing because the displacement and compaction of the soil, and grout column build up enough friction to meet capacity.” “The results were impressive when we Static Load Tested the piles,” recalls Shannon. “We were able to achieve the loads they needed with a 55-foot FDP pile.” The switch to FDP piles was also the most environmentally sound choice, according to Shannon. “They did all the remediation but still didn’t want any material to be exported,” he says. “FDP allowed us to keep all soils in the ground where they belong.”
BG 36 H the centrepiece drill
The FDP operation revolved around the BG 36 H Drilling Rig. Linde-Griffith owns a fleet of drilling
rigs, including two Bauers acquired from Equipment Corporation of America’s (ECA) New York/New Jersey branch. It was January 2018 when the BG 36 H executed test piles at Hackensack. The original plan was to have two rigs driving the FDP operation. The other was to be a BG 28 H. By the time permitting and environmental delays had been cleared, Linde-Griffith’s BG 28 H was tied up on other projects. It was agreed that the BG 36 H would be the only drilling rig on site. Linde-Griffith worked with ECA to equip the BG 36 H with 510-mm (20-inch) FDP Tooling to drill 1,322
FDP piles from 52 to 57 feet. Each pile consisted of a 20-inch grout column with a 10-inch-by-1/4-inch hollow pipe in the centre to provide additional shaft friction. The FDP piles created enough shear and base resistance so landing the pile on competent rock was unnecessary. Linde-Griffith executed each FDP pile in a sequence. First, the displacement tool bored down to the desired depth to loosen and densify the surrounding soil, leaving an open excavation. 4 1/2 to 5 1/2 cubic yards of 5,000-psi grout was then pumped into each hole under pressure through a hollow drill stem as the BG 36 H extracted the displacement tool.

“Our decision to bring in the larger 20-inch full displacement tooling combined with the quality control this machine offers made this project.” Mike Shannon

PILING, DRILLING & FOUNDATIONS
The rotation of the tool densified any loose material. The reinforcement cage was then dropped, and in some cases vibrated, into the fresh concrete to finish off the pile. “On an auger cast pile you’re relieving the pressure of the ground as you’re drilling down and the spoils are coming out,” Shannon explains. “Here, you’re actually creating more pressure because the soil is staying in the ground and pushing against the sides.” The FDP piles were laid out in a grid pattern with single piles around the perimeter for grade beams and caps
containing up to six piles for areas supporting the heaviest column loads. Drilling was not especially challenging in these soil conditions, but the grid pattern and FDP process itself caused increasing resistance with each pile. “In these clusters,” Shannon explains, “the first couple are always a lot easier because you don’t have any resistance. But the more piles and concrete you put in, the more you’re displacing and densifying the soil around the existing piles and it gets tighter and tighter.” Another challenge was that Linde-Griffith had to maintain a 10-
foot distance from piles with uncured concrete. “It’s based on how your layout is with the spacing of your piles, and how you plan,” says Shannon. “With this type of pile (FDP), you need to really project two to three days ahead to maintain production.”
FDP tooling critical to operation
Bauer tooling was critical to the FDP operation, according to Shannon. “It’s all Bauer displacement tooling designed specifically for this project,” he says. “It was engineered to achieve the required loads with
these soil conditions.” Friction was an issue. The soil conditions and grout acted like sandpaper on the tooling, especially the displacement bulb above the auger flight and the cutting teeth on the wear plates. “Quality control is very important out here so we change the tooling out once a week,” says Shannon, noting that extras are on hand at all times. “Then we just refurbish, re-weld, hardface, and bring them out when we need them.” “The main concern on this job was that a driven pile couldn’t achieve the load required,” says Shannon. “Our decision to bring in the larger 20-inch full displacement tooling combined with the quality control this machine offers made this project. The amount of information you get from that machine is unique and very impressive.” The quality control Shannon speaks of is driven by the patented Bauer B-Tronic System. Both Linde-Griffith and the project’s third-party engineer have access to such data as stroke count, grout pressure, and drilling depth via a desktop computer or mobile device. There is no second-guessing whether a pile is driven to the proper depth and contains the right amount of concrete. There was also a safety benefit since the engineer was able to monitor drilling from a safe distance because B-Tronic transferred the operator’s view to an iPad. The B-Tronic System doesn’t simply provide data. It also has a feature called B-Drive, which automates monotonous operations. Linde-Griffith’s operator, for example, was able to program the BG 36 H to drill to a specific depth by simply typing in parameters. During concrete placement, he plugged in the targeted grout volume and pressure. B-Drive automatically extracted the tooling once those numbers were achieved. Not only did this ensure a consistently grouted column, but it also allowed Linde-Griffith to share the exact amounts of concrete consumed with the owner. “We have it set up where I can view it from anywhere,” says Shannon, noting that he travels between sites all day. “I keep a laptop in my car so if I’m not here, I can see what’s going on.” Linde-Griffith was installing up to 25 FDP piles in less than 10 hours each day, which could have been even higher. Productivity was hampered by shorter days, muddy site conditions, and up to 45 minutes spent cleaning the BG 36 H and tooling at the end of each day. Linde-Griffith started drilling the first week of October 2019 and finished by February 2020. Strong production and smart planning resulted in the project being completed on schedule. Brian M.

CRANES & LIFT
LIEBHERR LAUNCHES MOST POWERFUL FOUR-AXLE ALL-TERRAIN CRANE LTM 1120-4.1 enters performance class previously populated by only five-axle cranes
he LTM 1120-4.1 is, according to Liebherr, the most powerful four-axle all-terrain crane ever built. The new 135-USt (120 t) machine breaks into a performance class which has previously been the sole preserve of five-axle cranes. As far as boom length is concerned, it is on a par with 240 US-ton (200 t) class cranes as its 217-foot (66 m) telescopic boom is the longest ever to be installed on a 4-axle mobile crane. Liebherr plans to start deliveries of the new LTM 1120-4.1 in autumn 2020.
Maximum lifting capacity and boom length
Delivering maximum performance on a fouraxle mobile crane is a concept which has been traditional at Liebherr for decades. For example, when the current LTM 1100-4.2 was launched in 2009, it set new standards in the fouraxle class with a lifting capacity of 22,490 pounds (10.2 t) on its 197-foot (60 m) telescopic boom. The new 135 USt (120 t) crane has added 18 percent to this value at the same length. What is more, the LTM 1120-4.1 can extend its telescopic boom to up to 217 feet (66 m), an additional 10 percent. This means it reaches the same level of many 240-USt (200 t) mobile cranes on the market. The new LTM 1120-4.1 delivers outstanding lifting capacity values, particularly with the boom fully raised. Its lifting capacity of 19,800 pounds (9 t) on the 217-foot (66 m) telescopic boom makes it ideal for erecting tower cranes and radio masts.
Lattice extensions enable the new 135 USt (120 t) crane to achieve hook heights of up to 308 feet (94 m) and radii of up to 210 feet (64 m). For this a 23-foot (7 m) lattice boom extension is installed as well as a 35- to 62-foot (10.8 to 19 m) double folding jib, which, as an option, can also be hydraulically adjusted between 0 and 40 degrees. A 6.6-foot (2 m) erection jib and a runner, which can be swung to the side, round off the equipment list.
Great economy and flexibility
The new LTM 1120-4.1 can tackle jobs which normally would require a four-axle crane, eliminating all the logistics work needed for the larger model. Because a four-axle crane delivers benefits in terms of licensing and route permits, it can tackle jobs faster and with greater flexibility. The design of a four-axle crane also enables it to work where there is insufficient space for larger cranes. On constricted sites, in particular, Liebherr’s VarioBallast and VarioBase innovations deliver enhanced performance, flexibility and safety for this new crane model. VarioBallast on the LTM 1120-4.1 enables the crane to operate with a ballast radius of 12.6 or 15.6 feet (3.83 or 4.77 m). The ballast radius can be reduced by 3 feet (940 mm) quickly and easily using standard, mechanically adjustable ballasting cylinders when site conditions get tight. The large ballast radius delivers higher performance and often also cost benefits by reducing ballast transport as many crane jobs can be com-
pleted using the system with fewer counterweights. The maximum of 68,300 pounds (31 t) of ballast is distributed so variably that in addition to the 26,400-pound (12 t) axle load version, uniform axle loads of 29,800, 33,000 or 36,400 pounds (13.5, 14.5 and 16.5 t) can also be achieved. That means benefits driving on construction sites and in countries where higher axle loads are permitted.
ECOdrive and ECOmode reduce fuel consumption and noise emissions
A six-cylinder Liebherr diesel engine in the undercarriage, which develops 330 kW/449 bhp and torque of 2,335 Nm provides the LTM 11204.1 with all the power it needs. The engine satisfies the new Stage V emissions directive and can also be built to comply with the regulations which apply in countries outside of Europe, for example Tier 4 for the USA or Stage III for low regulated countries. The ZF-TraXon gearbox is used to transmit the power to the crane’s axles. The ECOdrive has proven its value over several years – it delivers enhanced drive properties which both save fuel and reduce noise. Hillstart Aid makes starting on gradients easier. ECOmode for crane operations is now standard on Liebherr mobile cranes with a load-sensing control system – the crane controller calculates the perfect engine speed for the working speed selected using the control lever to avoid unnecessarily high engine speeds. That also saves fuel and makes the engine quieter. MAY 2020

LARGEST POTAIN CRANE IN NORTH AMERICA EXPEDITES B.C. DAM PROJECT
Potain MD 3200 MAXI tower crane is helping with the construction of the Site C Clean Energy Project – a third dam and hydroelectric generating station on the Peace River in B.C. The massive crane, which is the largest Potain crane to ever be used in North America, is working on the Generating Station and Spillways (GSS) Civil Works portion of Site C. When completed, the dam will be the province’s fourth-largest producer of electricity. After some research on the market, Aecon-Flatiron-Dragados-EBC Partnership (AFDE), the construction group in charge of the project, acquired the Potain MD 3200 crane specifically for penstock installations on this job. The crane arrived at the jobsite in February last year and started working in August, after being reconditioned to meet the group’s standards by EnCORE, Manitowoc Cranes – Tower Crane Division. According to Nathan Johnson, deputy intakes and penstocks manager at AFDE, the company needed a crane with the ability to receive oversized loads, like large steel penstock sections – many of which weigh over 45.4 t (50 USt) – at one location and move them with ease into place. The MD 3200 was erected on the Site C jobsite with its base attached to a custom rail track system that can move it along the length of the dam work site, nearly 107 m (350 feet). “The MD 3200 is the tool we needed to perform the work. The job would have been far more challenging without this crane,” he said. “We are very happy with the MD 3200’s performance – it’s the number one tool on the jobsite, as it can lift up to eight times more than any other tower crane on site.” The crane has been affectionately named by some as “Sir Pix-a-Lot.” “It’s outstanding, it’s definitely part of the skyline. When you’re driving into the site, if you don’t know how big it really is from the horizon, it’s massive,” Johnson said. Important features on the crane include its 101.1 m (331.7-foot) max height, 85 m (278.9-foot) jib, a capacity of 80 t (88.2 USt), and a full extension lifting capacity of 26 t (28.7 USt). To complete lifts up and over the height and length of the dam from a given point, AFDE requested the crane to be designed and configured at 78 m (255.8foot) height, 70 m (229.6 foot) jib, with 64 t (70.5 USt) and a full extension capacity of 37 t (40.8 USt). There are seven other Potain tower cranes working on site: two new MD 689 units and five MD 560 cranes. Construction on the Site C project commenced in 2015 and is expected to be completed in 2024. It will provide 1,100 megawatts of capacity, and produce about 5,100 gigawatt hours of electricity each year – enough energy to power the equivalent of about 450,000 homes per year in B.C.
80-TON TELESCOPIC CRAWLER FEATURES FOUR-SECTION BOOM The 80-ton TCC-800 telescopic crawler crane that debuted at CONEXPO 2020 comes with a new four-section 38 – 120 foot (11.8 – 36.5 m) full-power boom that reaches a maximum tip height of 184.5 feet (56.2 m) with full boom and Link-Belt’s SmartFly pinning system. Link-Belt SmartFly helps ensure proper fly erection and stowage sequence while minimizing work at height. This SmartFly system continues to get high marks from industry owners. The TCC-800 offers optional one- or two-piece 35- to 58-foot (10.6 to 17.6 m) fly. New to Link-Belt’s telecrawler lineup will be variable side frame track positions (V-CALC) on the TCC-800. “VCALC, in the case of the new TCC-800, offers the added flexibility to operate the crane with side frames in asymmetric configurations. Pulse 2.0 monitors actual side frame position, auto-selecting the correct chart,” said Scott Knight, product manager Lattice and Telescopic Crawler Cranes. TCC-800’s variable side frame combinations, new cab with 20 degrees of tilt and Pulse 2.0 offer an operator a multitude of options for any jobsite – everything from pile driving and bridgework to plant work or general construction. TCC-800 will utilize a stage 5 dual-compliant Cummins QSB 6.7 engine with 232 hp at 2,000 RPM for greater fuel economy, improved quiet operation and cold-start capability. Other advancements include pressure readout on all hydraulic circuits, viewable on Pulse 2.0 display. Total vision package with right-side swing camera, winch-view camera, and rear-view camera give the operator great jobsite visibility during setup and lifting. Single axis or joystick controls are also available both offering operator selectable foot or hand controls for travel operation. Textured paint on all vertical surfaces and slip-resistant paint on all horizontal surfaces improves durability and footing. New high-performance variable displacement pumps provide power control and load sensing on the TCC-800 for smooth functioning of all operating processes. Matching 3/4-inch (19 mm) grooved drums have 834 feet (254.2 m) of rope capacity with 18,603 pounds (7656.6 kg) maximum line pull and 485 fpm (147 mpm) maximum line speed. 26

ACTIVE STEERING SYSTEM ADDS ELECTRIC MOTOR TO CUT DRIVER FATIGUE
ack Trucks is helping reduce the effects of the rigorous demands of the jobsite by bringing its highly advanced Mack Command Steer active steering system to Mack Granite axle back models. Mack Command Steer reduces driver fatigue and can help cut muscle strain up to 30 percent by combining an electric motor with the existing hydraulic steering. Mack Command Steer for Mack Granite axle back models will be available for order in the third quarter. “Driving a fully loaded, heavy-duty construction truck is a physically demanding task, especially when you add the uneven terrain common to most jobsites,” said Roy Horton, Mack Trucks director of product strategy. “With the added steering assist from Mack Command Steer, we are able to reduce driver effort by 85 percent and significantly improve driver productivity and jobsite safety.”
Mack Command Steer monitors terrain, driver inputs and environmental elements more than 2,000 times per second through sensors found throughout the truck. Based on that input, the system provides variable
steering effort through its electric motor, which applies additional torque as needed to the steering. In addition to significantly reduced steering effort at slow speeds, Mack Command Steer also helps filter out

uneven terrain such as the holes, dips and ruts common to most jobsites. When such an irregularity is detected, the system reacts to counter the steering force, smoothing steering feedback and reducing the possibility of steering wheel “kicks.” “While drivers will experience a significant reduction in steering effort, particularly on uneven jobsite surfaces, Mack Command Steer brings many benefits to on-road driving as well,” Horton said. “The system will also compensate for situations, like strong winds and crowned roads, helping drivers maintain greater control so they can focus on the task at hand.” Mack Command Steer also features a unique return-to-zero capability that automatically returns the steering wheel to the zero or centre position in forward and reverse. This helps simplify tight maneuvers, such as backing a trailer or positioning a dump or mixer to unload.
XL SPECIALIZED TRAILERS
NEW LOW-PROFILE HYDRAULIC DETACHABLE GOOSENECK TRAILER DESIGNED FOR PAVING EQUIPMENT The XL Low-Profile Hydraulic Detachable Gooseneck (HDG) trailer can transport a multitude of machines, but has been specifically designed to haul paving equipment. This trailer has tapered front beams, offering an extremely low load angle of only four degrees. Additionally, 42-inch flip ramps provide extra loading assistance. “Operators will be able to load paving machines, rollers and much more with ease,” said Tom Hiatt, director of sales at XL Specialized Trailers. “At XL, we pride ourselves on coming up with solutions for customers to help simplify the transportation process, and this is certainly a solution for anyone working with paving equipment, which can be challenging to load onto a trailer.” The 13-foot gooseneck has a swing clearance of 110 inches, and the relief cut out in the gooseneck provides additional space between the truck and trailer. The sloped nose of the gooseneck protects the air and electric connections from damage. 28

With Apitong decking for increased durability, the 26-foot-long main deck features a loaded deck height of 24 inches and an 8-inch ground clearance. The trailer also offers a 14-foot-long rear deck that has a 40-inch loaded deck height.
The Low-Profile HDG offers many features from tie-down points to lighting. For starters, the main deck offers seven pairs of bent d-rings along the outer beams, 13 chain drops per side on the outer rails, four chain drops around the toolbox and swing out outriggers on 24-inch centers. The toolbox, located at the front of the main deck, provides a storage area for chains and other items, while the deep bucket well in the rear provides an area for an excavator bucket to ride safely without detaching the lower boom section.
COMPACT ROTATING TRACKED CARRIER CAN OFFLOAD MATERIALS FASTER Terramac’s innovative RT7R, unveiled at CONEXPO 2020, is the company’s most compact rotating unit. Built with a rugged upper frame that rotates a full 360 degrees, the Terramac RT7R can carry and dump up to 14,000 pounds of material at any position, even while driving. This unique functionality allows the RT7R to offload materials faster than a standard straight frame crawler carrier since the tracks do not need to be counter-rotated to drive another direction. “The two biggest features that set the RT7R apart are its compact size and unique rotational functionality,” says Matt Slater, vice president of Sales and Marketing at Terramac. “The RT7R is an excellent solution for jobs that are in tight spaces but don’t require the payload of a larger unit. And because it is small and compact, the RT7R can be easily loaded onto a tag trailer and hauled by line trucks from jobsite to jobsite.” The RT7R is built to be nimble while providing the power needed to accomplish the task at hand. This new unit features a compact footprint of 17 feet 3 inches by 8 feet 1 inch and boasts travel speeds up to 6.7 mph, ensuring quick cycle times to keep productivity levels on point. The 24,080-pound machine is powered by a 165-hp Cummins B4.5 Performance Series Tier 4 Final / EU Stage V engine, enabling it to boost jobsite productivity while remaining highly fuel efficient, regardless of the application.
In addition to power and efficiency, the RT7R showcases Terramac’s rubber track technology. Flotation from the unit’s rubber tracks and a fully loaded ground pressure of just 5.5 psi, allows the RT7R to travel lightly in adverse ground conditions, climb faster on rugged terrain, and reach remote areas while minimizing environmental damage
and land restoration costs. The RT7R is ideal for work in tight spaces and environmentally sensitive areas. Terramac currently offers a heavy-duty rock bed on the RT7R to maximize hauling efficiency for moving dirt, brush or rugged materials such as rip rap. The RT7R comes standard with a rollover protective structure (ROPS)
and a falling object protective structure (FOPS). The RT7R is ergonomically designed with upgraded features, including a wide access door for ease of entry and exit and windows on all sides for increased visibility. In addition, multiple access points were designed for fluid/filter checks and easily accessible panels are provided for hassle-free maintenance.
Mammoet completes heavy lift and transport work for Calgary ring road project Mammoet has completed the heavy lift and transport scope for the Southwest Calgary Ring Road (SWCRR) Project, which began in 2017. The SWCRR will improve the safe and efficient movement of goods and people in and around the Calgary area, reducing overall traffic congestion and providing effective routes for commercial vehicles transporting goods. Contracted by KGL Contractors Partnership; a joint venture partnership between Kiewit, Graham and Ledcor, Mammoet assisted in the construction of 45 bridge structures on the southwest portion of the ring road. Mammoet’s expertise and combined crane and transport equipment was imperative in being able to handle more than 1,000 girders, as well as hoisting them into place. While executing the project, Mammoet teams used a variety of trailers and cranes – ranging in capacity from 58.9 to 453.5 t (65 to 500 USt) – to install the bridge girders. The largest units weighed approximately 156 t and were up to 197
feet (60 m) in length: these are some of the largest girders to have ever been installed in the area. During the construction, Mammoet teams transported and installed 20 of these oversized girders. Despite working through two winter seasons – where weather is unpredictable and brings arctic sub-zero temperatures – as of March, Mammoet has concluded their scope on schedule. The southwest portion of the ring road is expected to be open to traffic in 2021. “The Calgary Ring Road was a challenging project due to its large volumes and somewhat recurrent changes,” shares Gustavo Carnelli Mariotto Ferreira, manager of Transport and Projects for Mammoet. “By coming together as a team, we were able to adapt to various new oversized requirements and reduce external costs.” Mammoet has been involved in various infrastructure projects across Canada, some to mention include the Valley Line LRT in Edmonton, and the St. Jacques Bridge in Montreal.

SKYJACK REVAMPS L ROUGH-TERRAIN S A Q&A WITH COREY CONNOLLY, By Kaitlyn Till, Editor in Chief Kaitlyn Till: What trends are driving Skyjack’s introduction of its largest rough-terrain scissor lifts? Corey Connolly: Our new line of large rough-terrain scissor lifts is a combination of replacing existing products (30-, 40- and 50-foot models) as well as introducing a new one (60-foot model). Looking at the replacement models, the need to update our existing models was primarily being driven by a few different things: changes to North American designs standards, changes to European emission standards and changes to customer/user expectations. Looking at our existing models, other than paint, label and engine changes, we had not made any updates to them since they were introduced in the 1990s. Platform heights and capacities on our existing machines were no longer meeting all of our customer’s needs. Increasing platform heights from 50 feet to 53 feet on our 9253 represent the difference between being able to work on a five-storey building and a six-storey building. Like a lot of product introductions, customer demand is the primary driver behind introducing our newest and largest rough-terrain scissor lift model – SJ9263 RT. This isn’t a new class that we are creating, however we recognize that with growing demand it can no longer be viewed as a niche segment. Our customers see a growing demand from their customers in applications that are no different than what would traditionally be filled by 30-, 40- and 50-foot machines, except that they are asking to go higher. In the past you were limited to either going to a totally different product (a boom) or scissor lift that was larger (>80 feet) than what was even required (and with availability more geographically 30

Y, PRODUCT MANAGER limited to Europe). There was nothing available in that 60- to 70-foot working height range. With product offering in this class being fairly limited, and changes coming to North American design standards, it was a perfect time to look at this class and include it as part of our larger project to redesign our existing large rough-terrain scissor lifts. KT: What access solutions can these large scissors replace and what are the advantages of using a large rough-terrain scissor over other access solutions? CC: Within established access markets like North America, Europe and Australia, most users understand what applications are more suited for booms and which for scissor lifts; you are not really replacing other solutions but further enhancing the existing ones. In other developing access markets there is still a bit of education needed to identify applications that may be more suited for a rough-terrain scissor lift as opposed to a boom. If you need clearance, or you need to constantly reposition the platform or if you only need limited people/ material in the platform then a boom may be a better option. If you require more material, more tools, more people, a larger work area, and you have no reach constraints other than height, then a rough-terrain scissor lift is likely the more appropriate solution. KT: What are the key features on Skyjack’s new large rough-terrain scissor lifts? CC: When we determined that we were going to replace our existing line of large rough-terrain
scissor lifts, we not only identified some areas that could be improved but we also identified features that we would like to maintain and carry over to the new machines as well. We not only looked at improving platform heights and platform capacities, we looked at maintaining our axle-based drive system – a low maintenance feature that provides optimal jobsite navigation. We also looked at maintaining large over platform dimensions while also minimizing the gap between the platform and the outside of the tires (the widest part of the machine) for the best clearance when doing work outside of the platform. We also looked at adding features like a <25-hp engine and solid tires, as well as updating our control system to better integrate with our telematics solution – ELEVATE. All of these features will positively contribute to our customers’ low cost of ownership. KT: What should a contractor consider when purchasing or renting a large rough-terrain scissor lift? CC: When looking at renting or purchasing a large rough-terrain scissor lift it is important that a contractor considers the work they are doing but also where they are doing it. Will it be indoors or outdoors? What type of surface will the machine be driving and lifting on (outriggers vs. no outriggers)? How high do they need to lift and how much material/tools/people are needed in the platform? How large of a platform or work space do they need? Do they need any other product/ model specific attachments or options (ie. pipe rack or material handling stand)? HEG
SKYJACK’S HIGHESTREACHING SCISSOR LIFT EVER Skyjack’s highest-reaching scissor lift to date is the SJ9263 RT. It offers a working height of 69 feet (21.03 m) and Skyjack says that it increases opportunities for rental companies with its ability to make work at six stories possible. The new rough-terrain scissor lift is rated for four people and the platform spans up to 23 feet 4 inches (7.12 m) with the dual extension deck option. Common features with the rest of Skyjack’s full-size range include axle-based four-wheel drive, AXLDRIVE; a SMARTORQUE engine, pairing peak performance with low maintenance; and fully accessible service components. “Right now market standards for full-size rough-terrain scissors are the 30- to 50-foot models we’ve offered for years,” said Barry Greenaway, senior product manager at Skyjack. “If a rental company is looking to take a step up from there the next best option in North America is a boom, and in Europe is the specialized 90- to 120-foot classes. We found a way to offer something that’s a step between the two options.”

EQUIPMENT MAINTENANCE & MANAGEMENT
HOW TO PERFORM DAILY MAINTENANCE ON SCISSOR LIFTS By Mike Flanagan
lab and rough-terrain scissor lifts can be crucial to jobsite productivity, and by adhering to a few daily maintenance and inspection requirements, operators can ensure maximum uptime on jobsites. Even if it’s not always convenient to take the time to perform these duties, operators will find that it is worth every minute if scissor lifts are ready to work and continue to perform in the field – it is easier, and less expensive, to deal with things little by little rather than have something fail and face the consequences.
Preventive maintenance: whose responsibility is it?
Preventive maintenance tasks outlined in the equipment’s operator’s manual should only be completed by a qualified maintenance technician, authorized by the equipment owner. The equipment operator is not responsible for, nor authorized, to conduct this kind of maintenance. That being said, operators do have the responsibility for completing inspections prior to, and after, each work shift to ensure the machine is in proper working condition.
Before work begins each day
Prior to start up each day, scissor lift operators must complete pre-operation and workplace inspections, as well as function tests, as outlined in the operators’ manuals.
A workplace inspection helps the operator determine if the jobsite is a suitable and safe space to operate the scissor lift. This inspection should be performed by the operator prior to moving the scissor lift to the workplace. The operator’s manual is a good resource to identify the most common hazards that may be encountered on jobsites, and it’s always a good idea to check with the site supervisor or safety manager for any hazards unique to a particular jobsite. On any aerial worksite, scissor lift operators need to be aware of, and avoid, the following hazardous situations including: drop-offs or holes; bumps, floor obstructions or debris; sloped surfaces; unstable or slippery surfaces; overhead obstructions; high-voltage conductors; inadequate surface support to withstand all forces imposed by the machine; wind and bad weather conditions; the presence of unauthorized personnel; and all other possibly unsafe conditions. It’s important for operators to al-
ways remember that it’s their responsibility to read and remember the workplace hazards, as well as to watch for and avoid these hazards while moving, setting up and operating MEWPs. When in doubt, operators should pause the job and consult the jobsite supervisor or safety manager.
The pre-operation inspection is a visual inspection to be performed by the operator prior to each work shift. This inspection is designed to discover if anything is apparently wrong with a machine before the operator performs the function tests. The pre-operation inspection also serves to determine if routine maintenance procedures are required. For example, the operator should inspect the wheels, lifting mechanism, and platform for any damage, which should be repaired prior to use. Once the repairs are completed, the operator must perform a pre-operation inspection again before going on to the function tests.
Function tests are designed to discover any malfunctions before the machine is put into service. The operator must follow the scissor lift manufacturer’s step-by-step instructions, found in the operator’s manual, to test all machine functions before work can begin. It is important to know that a malfunctioning machine must never be used. If malfunctions are discovered, the machine must be tagged and removed from service. As a reminder, repairs to damage or malfunctions discovered during the pre-operation inspection or function tests may only be made by a qualified service technician, according to the manufacturer’s specifications. After repairs are completed, the operator must perform the pre-operation inspection and function tests again, prior to putting the machine into service.
When work is done for the day
At the end of the work day, there are several important tasks for the operator to complete before going home for the day. The first step that should be taken is for the operator to lock out the scissor lift. The operator needs to select a parking location on a firm, level surface that is clear of obstructions and traffic. Once the scissor lift is parked, the operator should lower the platform, turn the key switch to the “off” position and remove the key to secure form unauthorized use.
When the machine is secured at the end of the day, the batteries should be charged in accordance with the manufacturer’s recommended guidelines outlined in the machine’s operator’s manual. Proper battery condition is essential to good machine performance and operational safety. Typically, this task is done by plugging the battery charger into an AC wall outlet and allowing the batteries to completely charge, but it is important to review the manufacturer’s specific requirements, which may include: to not use an external charger or booster battery; to charge in a well-ventilated area; to use the proper AC input voltage for charging as indicated on the charger; and only use an authorized battery and charger that is appropriate for the machine’s make and model. When the operator goes to charge the battery, it is important to make sure the batteries are connected before charging. Additionally, batteries should be in a well-ventilated area; some scissor lift manufacturers may require battery compartments to remain open for the entire charging cycle. If an operator is charging standard wet batteries with vent caps, it is important to remove the battery vent caps and to check the battery acid level. Operators must wear appropriate personal protection equipment (PPE) to complete this task. If it is necessary to fill up the batteries, the operator should add enough distilled water to cover the plates, at the bottom of the fill tube, but not overfill prior to the charge cycle. Then, the operator should replace the battery vent caps and connect the battery charger to a grounded AC circuit. The charger will indicate when the battery is fully charged. The operator should then again check the battery acid level when the charging cycle is complete. Operators should check the operator’s manual for specific infor-
mation about the particular machine and batteries as some batteries may be sealed and not require refilling. It is best for the batteries that they are charged for an extended of time, such as overnight, because opportunity charging – plugging the scissor lift in during lunch time or for short periods of time – can be detrimental to battery longevity. Most scissor lifts have a battery-level indicator on the platform or ground controls. Operators should use this important diagnostic readout to determine the battery level and take the machine out of service when the batteries are low on charge. On many scissor lift makes and models, when the battery level gets too low, machine functions may be disabled.
In addition to the operator’s daily tasks, preventive maintenance on scissor lifts should be performed quarterly, annually and every two years by a person trained and qualified to perform maintenance on this type of machine and be done according to the procedures found in the service manual for the machine. If a MEWP has been out of service for more than three months, it must receive the quarterly inspection before being put back into service. Sticking to a regular maintenance routine, including the important daily tasks as outlined in the operator’s manual, can ensure that a MEWP is ready to go when it is needed it. Operators should consult the jobsite supervisor and safety manager, as well as the rental house’s fleet manager, to get more information on daily maintenance tasks that need to be completed. This will ensure that operators have the right tools, training and resources available to maximize jobsite productivity. Mike Flanagan is Genie product manager, Terex AWP.

BUILDING POWER SOLUTIONS FOR THE FUTURE OF CONSTRUCTION Commercial and environmental pressures are prompting research into alternative power By Steve Nendick
ith increasingly stringent emissions legislation and advances in alternative technologies, what is the future of power in the construction industry? Key to embracing changes across the industry will be the ability for manufacturers to collaborate with power providers to find the solutions that continue to meet market expectations of performance, uptime and running costs. The great diversity of plant machinery design and working conditions means that power solutions can never be a one-size-fits-all. As progression in electrification is made then its suitability for certain types of industrial machines will increase. But, by the same token, the advances in ultra-clean diesel technology are demonstrating that it will continue to be a key power source for plant machinery for the foreseeable future.
Electrification is one of the buzzwords for sustainability in passenger transport today with the increasing availability of car and bus solutions. Its uptake in construction will take longer though, due to cost and charging concerns. The initial interest is being seen on compact machines, those that operate in urban areas with easy access to charging. An example of this is Cummins’ prototype electric
Cleaner diesel engines like Cummins’ Performance Series have a future in construction power. 34

mini excavator, powered by eight BM4.4E flexible battery modules. At 35kWh, the machine is a test platform for Cummins lithium-ion battery technology across a wide range of compact installations. Currently, battery technology doesn’t meet the duty cycle and working hour expectation for larger equipment such as excavators or wheel loaders. Cummins’ investment in battery technology ensures it will be ready as battery capability increases and cost reduces.
The rise of hybrid technology
Hybridization remains a feasible way to bridge the gap between full-electric and diesel on larger more power-hungry machines. It offers the power density of diesel, with the option to run on batteries in certain locations that prohibit emissions. Similarly, it offers end-users flexibility when there is no charging infrastructure at the work site. The key benefit of the technology is the ability to pair up a smaller diesel engine with a hybrid driveline to save fuel costs, servicing costs and reduce overall emissions (NOx, PM and CO2). A hybrid using a Cummins Performance Series engine, paired with a battery and electric motor, has the option of running on ultra-clean diesel for heavier duty cycle tasks, or areas with limited charging capability, as well as switching to electric power for work in ultra-low-emission zones or where lower noise is needed. The use of electric motors also removes the need for traditional gear shifting, which could make equip-
Construction equipment continues to rely on diesel. Currently, only diesel power can match the intense duty cycles of most construction equipment as well as the combination of power density, work capability and flexibility required. Contrary to popular perception, the technology involved in diesel power has in fact never been cleaner. Cummins is pushing the diesel engine onto the next rung of its revolutionary ladder with its ultra-clean Performance Series. Meeting both EPA Tier 4 Final and EU Stage V emissions regulations, they deliver on average 10 percent more power and 20 percent more torque across the 100–430 hp range when compared to their predecessors. The engines are smaller, lighter and simpler than ever before, emitting ultra-low NOx and PM emissions due to innovative aftertreatment technology. This translates to more performance with lower installation costs for OEMs and lower running costs for operators. The four-cylinder F3.8 and B4.5 Performance Series engines achieve increases in power and torque, giving manufacturers the opportunity to improve machine capability and offer more value to their customers. Alternatively, there is a potential to downsize the engine to one of lower displacement, reducing costs while preserving the productivity of their existing machines. Developments seen in Cummins Performance Series engines point to way to the future of diesel; smaller, lighter, cleaner and more efficient with more capability.
Finding the best solutions
Cummins is committed to developing solutions for all off-highway requirements and continues to progress gains in energy efficiency, emissions reduction and even lower running costs for customers. This is through a range of technology, not just electric and renewable fuels, but demonstrating diesel’s expanding capabilities in a sustainable future. The reality of near-future power solutions is likely to be a combination of electrification, hybridization and advanced diesel technology. Investing heavily in R&D ensures Cummins can deliver this effectively, with almost $1 billion invested each year to develop a diverse power portfolio. As progression in electrification is made then its suitability for industrial machines will increase. However, no viable alternative has yet emerged that can match the workhorse credentials of diesel power. For the global construction sector, the differences in scale, equipment duty cycle and operating location means there is no real “one size fits all” power solution. Steve Nendick is marketing communications director with Cummins.

KUBOTA ENGINE AMERICA
300-HP ENGINE ADDS LARGE DISPLACEMENT POWER TO DIESEL LINEUP Kubota Engine America launched the S7509, a highpower-density, 300-hp, large-displacement industrial diesel engine, at CONEXPO 2020. The new addition to Kubota’s 09 Series was announced by Kubota Corporation at the company’s headquarters in Japan on March 2. This new large displacement industrial diesel engine will comply with EU Stage V emission regulations. “Kubota integrates state-of-the-art design to produce high performance and durability in all of our engines and the S7509 will be no exception,” Tomokazu Matsushita, president of Kubota Engine America, said. “The S7509 will further expand the 09 Series and Kubota’s goal is to become the number one supplier of engines up to 300 hp.” The compact 7.5-litre, 6-cylinder engine features low fuel consumption with its optimized, direct-injection combustion system. It provides 100 percent power take-off at the flywheel and fan side, as well as selection of flywheel housing and flywheel for OEM coupling. The S7509 provides great versatility because the exhaust side auxiliary PTO takes up to two hydraulic pumps in addition to the intake side PTO. The engine also features a one-side easy maintenance and automatic belt tensioner. Mass production of the S7509 will begin in 2023. Kubota Engine America also featured a prototype of its Micro-Hybrid System, which made its North American debut at CONEXPO 2020. Kubota’s Micro-Hybrid System provides power assistance instantaneously
during peak overloads to the engine providing an additional electrical power boost of up to 10 kW. The immediate torque offers an efficiency boost at the most crucial time while recuperating and recharging its battery pack when not initiated. Kubota first demonstrated its concept at Intermat in 2018. In 2019, at bauma, Kubota displayed the prototype system installed in a forklift. The Micro-Hybrid System started with the 1.8-litre engine and now it has expanded to a larger 3.3-litre engine. The peripheral key components, such as DC-DC converter and 48V lithium ion battery have also been enhanced.
“Kubota’s Micro-Hybrid System allows for engine downsizing with maintaining performance, productivity and efficiency,” Matsushita said. “The enhancement of the lineup will provide benefits to more OEM customers and equipment users.” In addition to all the new engine products, Kubota Engine America also launched its service mobile application at CONEXPO 2020. The app connects users to an engine service dealer, while also providing product registration and a knowledge centre with resources on maintenance schedules, operation manuals and warranty information.

HYBRID CONCEPTS LOOK TOWARD FUTURE ELECTRIFICATION OPTIONS
Perkins displayed a series of hybrid designs based on its successful Syncro engine line
he diesel engine industry is moving forward steadily, with new approaches to engine design, efficiency and emissions answering the call to develop more eco-friendly equipment. CONEXPO 2020 brought numerous new initiatives from Perkins in that vein; along with the introduction of new engines, the company showed its efforts to improve environmental friendliness with several concept hybrid engines. In addition, the company’s aftermarket division introduced new eco-friendly filtration options that will protect engines and the environment at the same time. The successful Syncro engine line has provided Perkins with the basis of its four hybrid engine concepts introduced at the event. These designs, displayed on the Syncro 2.8 engine, are the second generation of design work in the hybrid-electric range. Instead of going with a hybrid system tied into the crankshaft, the new engines are designed with a flywheel-based generator, which offers a scalable solution that can provide OEMs with a variety of options in their equipment. With this hybrid approach, there are options that Perkins is exploring, but all allow the engine to run at 75 hp, meaning there’s no need for diesel exhaust fluid. In addition, pairing with batteries can mean providing equipment owners with an electric-only option. “Perkins is focused on delivering more choice and increasing value to our customers. The four hybrid
concepts we’re showcasing are examples of future technologies that will take machine efficiency to the next level,” noted Tom Nankervis, electrification marketing manager. “With our range of hybrid en-
E-FLYWHEEL TURNS DIESEL INTO EFFICIENT, SUSTAINABLE ENGINE SOLUTION FPT Industrial has unveiled the F28 Hybrid, a diesel engine paired with an e-flywheel, resulting in an efficient, compact and sustainable solution for off-road applications. With this hybrid version, FPT Industrial takes a step further into a modular and multi-power powertrain approach. The 2.8-litre hybrid engine was developed to offer the ideal performance for compact machinery offering enhanced productivity and improved efficiency. With four in-line cylinders, the thermal engine delivers a maximum power of 74 hp, while the electric motor adds 27 hp of continuous power and 40 hp of peak power. Light construction machines such as skidsteer loaders, drum rollers and backhoe loaders benefit from the peak power at certain times to complete their missions more efficiently. “Our vision for the powertrains of the future includes some of the main features of the new F28 Hybrid,” said Pierpaolo Biffali, 36

vice president of Product Engineering at FPT Industrial. “This engine highlights our commitment to alternative propulsion and demonstrates our engineering abilities with its efficiency and compactness advantages.” The F28 Hybrid combines high performance and low fuel consumption in a compact package. It also features enhanced system efficiency, simple architecture, fast operation, and optimized Start & Stop for a smoother engine start. The integration of the engine’s hybrid architecture is based on FPT Industrial’s proprietary control software, reinforcing the Brand’s role as a full system integrator. FPT industrial is also highlighting the commercial launch of the F28 for North America and its availability for the construction segment. Unveiled last November, the F28 is available in diesel, natural gas and now hybrid versions, becoming a real modular and multi-power engine.
gines, customers can choose to downsize their engine and use the hybrid power for peak-load, or they can reduce output from the diesel engine, choosing to lower fuel consumption up to 20 percent.” With many OEMs focused on deploying their Stage V solutions at this point, Perkins is taking the opportunity to develop hybrid options as the next step in engine development once the current emissions goals have been reached. In addition, Perkins launched several engines at CONEXPO and expanded some service and aftermarket offerings to help make life easier for technicians and mechanics working with Perkins engines. The new Ecoplus oil filters, available on several Syncro engines, were released last summer. Designed as an insert rather than contained within a metal can, the Ecoplus filters slide into a filter housing mounted on the engine. The housings hold the filter upright – meaning when they’re removed the oil drains into the engine rather than onto the floor or the technician. A bypass valve in the filter housing holds oil in the filter when the engine shuts down, which means there is immediate oil flow at startup, providing better protection for the engine, turbochargers and other parts. Perkins’ My Engine app has also been updated, with the addition of thousands of service manuals. Available in multiple languages, the digitized manuals can be read on a portable device, which allow users to zoom in and see detail on diagrams. This makes the technicians’ job much easier.

LAST WORD RESILIENCE WILL AID CANADIAN BUSINESSES IN RECOVERY EFFORTS RYAN GREER, SENIOR DIRECTOR AND CANNABIS POLICY LEAD, CANADIAN CHAMBER OF COMMERCE
ncertainty is the new normal for the Canadian economy. Businesses and governments at all levels are scrambling to adjust on the fly to COVID-19 by trying to contain a health crisis while managing the economic crisis it has unleashed. New support measures and programs are being designed and implemented at previously unimaginable speeds as governments try to preserve jobs, support Canadians who have lost theirs and keep as many firms afloat as possible.

look to automation to maintain operations during future crises and reduce risk. Canadians will need reskilling, upskilling and skills training programs to get them back to work. Education and training will also change, which will include more online learning and durable skills with a focus on both work-integrated and lifelong learning.
Navigating all of these measures, which are being adapted daily, is a challenge for all businesses. That is why the Canadian Chamber of Commerce, in partnership with the federal government, has established the Canadian Business Resilience Network (CBRN) – at www.CBRN.ca – to help the business community prepare, persevere and ultimately prosper in the face of the COVID-19 pandemic.
Despite the immediate and severe impacts affecting businesses, CBRN is also a forward-looking campaign that will help position Canadian companies to drive long-term economic recovery. While no one can predict with any certainty the economic, political and cultural changes this crisis will have on Canada and the rest of the world, we know these changes will be significant. The high level of collaboration among governments, businesses and civil society managing this pandemic should give Canadians confidence about our collective ability to deal with the long-lasting changes it will bring.
One thing we can predict with certainty is that the construction industry will play a central role in the recovery. The federal government has already indicated that infrastructure will be a central component of stimulating the economy and has begun consulting on “shovel ready” projects that can help generate new economic activity in 2020. The Canadian Chamber of Commerce supports this approach and will encourage all levels of government to focus on the projects that are truly shovel ready and can help get Canadians back to work as soon as possible.
CBRN is a coordinated, business-led campaign providing a consistent and reliable flow of accurate and up-to-date information to businesses. It provides tools and supports for continuity efforts, while
The most pressing recovery issue for governments will be getting Canadians back to work and achieving a return to pre-COVID employment levels, which will take time. Employers might increasingly
As we look ahead, businesses and governments must not just undo the damage inflicted by COVID-19, but also aim higher than the pre-COVID status quo to achieve Canada’s full economic potential.
Since 1925, the Canadian Chamber of Commerce has connected businesses of all sizes, from all sectors and from all regions of the country to advocate for public policies that will foster a strong, competitive economic environment that benefits businesses, communities and families across Canada. With a network of over 450 chambers of commerce and boards of trade, representing 200,000 businesses of all sizes in all sectors of the economy and in all regions, the Canadian Chamber of Commerce is the largest business association in Canada. 38
