Despite Challenges, Industry Continues to INNOVATE

A

IN THE NEXT ISSUE

s we approach the end of 2020, it’s hard not to reflect on what a unique year it’s been for the world. However, despite the many challenges, our industry continued to innovate and evolve this year to meet the needs of customers. Manufacturers adapted to new ways of doing business, and many OEMs and component suppliers enhanced their R&D efforts to ensure they could continue bringing new technologies to market. On pg. 12 you’ll find our article about the new GM Defense Infantry Squad Vehicle which was developed—and the first vehicles delivered—in 120 days, demonstrating the ability of the OEM to meet the U.S. Army’s needs in a quick timeframe. Innovation can be seen in all parts of a machine these days as evidenced on pg. 14 in our look at the methods being used by the fluid power industry to create smarter systems through the integration of sensors and software. In addition, on pg. 24 we examine how equipment cab designs are continuing to evolve to enhance the comfort and productivity of machine operators. In this issue you’ll also find the winners of our annual Top New Products award which honors technologies released withPUTILOV_DENIS  STOCK.ADOBE.COM in the past year in each of the six main topic categories on which we focus our content. Winners of this year’s award can be found on pg. 30. Much like the industries we cover, OEM Off-Highway also continues to innovate so we can bring you the information you want in a way that is most beneficial. As such, this year we have started a new video interview series called Design & Engineering Insights as well as a weekly podcast series, both of which can be found on our website and cover the latest technologies and trends in the heavy equipment industries. Have a topic you think we should cover in either series? Let us know!

GM Defense Delivers Infantry Squad Vehicle to

U.S. ARMY

by Sara Jensen

STEVE FECHT AND GENERAL MOTORS DEFENSE, LLC

G

M Defense LL, which is a subsidiary of General Motors (GM), recently made its first delivery of the company’s Infantry Squad Vehicle (ISV) to the U.S. Army. The ISV is a light and agile all-terrain troop carrier designed to transport up to nine infantry personnel and their equipment. This is the first major award and delivery for GM Defense since it was re-established in 2017. The vehicles were delivered as part of a $214.3 million contract awarded to GM Defense by the U.S. Army in June. GM Defense will manufacture a total of 649 ISVs as part of the contract, as well as support production of up to 2,065

12

vehicles with additional authorization over 8 years. “One hundred and twenty days from contract award to delivery is a significant milestone, and I am very proud of the team for this accomplishment,” said David Albritton, President of GM Defense, in the press release announcing the delivery of the ISVs. “We’re leveraging General Motors’ engineering prowess and immense manufacturing capabilities to bring transformative solutions to the military vehicle market. Our initial success with the ISV shows our commitment to our customer and highlights our unique right to win in the military mobility market.”

Developing the right design for the mission The ISV is based on the design of GM’s Chevrolet Colorado ZR2 truck architecture. Ninety percent of the components used are proven, commercialoff-the-shelf (COTS) parts which helps ensure their reliability. Weighing 5,000 lbs. (2,268 kg), GM Defense says the ISV was specifically engineered to meet military requirements and provide rapid ground mobility. Doing so ensures the safety of military personnel in the various environments in which they may be operating. GM Defense says the vehicle is light enough to be sling loaded from a UH-60 Blackhawk helicopter and to

fit inside a CH-47 Chinook helicopter, making air transport from one destination to another easier for the U.S. Army. A rollover protection system (ROPS) on the ISV further helps to ensure the safety of military troops by keeping them securely in the vehicle should there be a rollover incident. In addition, the use of COTS parts makes it easy to get spare parts if necessary and minimize downtime which is especially critical for military personnel who are often working in dangerous locations. “During Soldier testing, the feedback we received was paramount in delivering a vehicle that met Soldiers’ needs, while maximizing safety and performance and taking their comfort into consideration,” said Mark Dickens, GM Defense Chief Engineer, in the press release announcing delivery of the ISV. “The production ISV we’re delivering today is an evolution from our original prototype design, and it’s certainly a vehicle that is a source of pride for the team.” GM Defense partnered with Ricardo on the development of the ISV. Ricardo lead the Integrated Product Support (IPS) portion of the project which included technical manual development, new equipment training, provisioning, total package fielding, and field service support. The company also collaborated on technical areas such as safety, reliability and cybersecurity. “The ISV will showcase the speed at which the Army can rapidly produce, field, and sustain new equipment by

leveraging a proven commercially available vehicle and the global supply chain infrastructure of General Motors, supported by Ricardo,” said Chet Gryczan, President of Ricardo Defense, in Ricardo’s press release announcing the partnership with GM Defense. “Ultimately, our combined goal is to provide best-in-class product and

sustainability to help ensure our warfighters have confidence with the ISV throughout its lifecycle on and off the battlefield,” said Albritton. According to GM Defense, the ISV will provide the U.S. Army with manufacturing efficiencies, ease of maintenance and a well-established global supply chain. |

machine systems autonomously, do it in real time and deliver it to machine end-users and OEM suppliers so they can maximize the uptime and flexibility of their machines,” says Terry Hershberger, Director, Sales Product Management & eSystems, Bosch Rexroth. In hydraulic systems specifically, there are two major trends driving increased intelligence says Ben Hoxie,

Director of Engineering, Power and Motion Controls at Eaton. The first is distributed intelligence enabled by low-cost computing and sensing which gives rise to all types of new machine functions. He says Eaton refers to this intelligent machine movement as Dynamic Machine Control. The second key driver is “a step change in connectivity through mobile and industrial

communication protocols that can cost effectively transmit significantly more data than before. This improved connectivity is enabling big data innovations that will yield new insights into how machines operate and the behavior of machine operators,” he says. Automation is also driving the push toward increased intelligence. “Digitalization of the machine, by incorporating robust controllers, sensors/feedback devices and the connectivity unit, provides for additional workflows or other apps that could allow for remote controlled worksites to be managed more safely,” says Hershberger. “A fleet manager could control an area that the vehicle is allowed to operate, and of course provide for diagnostics of the system, however, it is not without challenges.” Overall, creating more intelligent systems helps improve safety, productivity and cost of operation through better machine control, says Hoxie. “One example of how an intelligent hydraulic system has delivered such benefits is our Boom Stability Control solution. By reducing boom oscillation up to 75%, the system delivers both safety and productivity benefits to end users,” he explains. “Another example is autoguidance steering solutions. Eaton’s system combines our GFX GPS receiver, SFX safety-rated controller and SBX advanced steering valve to enable automated and semi-autonomous vehicle steering operation.”

Methods for adding more intelligence There are a variety of ways manufacturers are creating smarter hydraulic systems, including incorporation of more sensors and software. Hershberger says Bosch Rexroth’s BODAS (Bosch Rexroth Digital Application Solutions) portfolio of IoT solutions, software and electronic hardware exemplify the digital enhancements the company is making for off-highway equipment. “Together with Bosch, we also offer the suitable IoT infrastructure and cloud-based analytical apps,” he says. “It combines competence and application experience in the decisive fields of mobile hydraulics and electronics, edge analytics and IoT.” In general, he says the company has enhanced the integration of sensors where necessary in order to provide real-time data on hydraulic performance metrics. Additionally, Bosch Rexroth is engineering its digital technology offerings—including hardware, software, and connectivity and analytical systems—to work together as complete solutions. Hardware options include an open, scalable and freely accessible mobile electronics platform which consists

of control units, connectivity devices, sensors and human machine interface (HMI) components such as joysticks and displays. Bosch Rexroth’s software is modular and includes tools for programming, parameterization and diagnostics, and is based on deep insight into hydrostatic and electrohydraulic functions, says Hershberger. “The fundamental building blocks of IoT are the ‘things’,” says Hoxie. As such, Eaton is developing a suite of intelligent devices such as its CMA valve with deeply integrated sensing and control. Its AxisPro valves feature onboard white space which allows users to build application-specific solutions and thus tailor the valves to the needs of the machine design. “We’re also continuing to build upon our Pro-FX suite of controls and software solutions,” he says. “This library of machine control function blocks enables quick and easy system development and tuning to match machine builders’ needs. Finally, on the connectivity and cloud storage side, our TFX telematics solution enables machine builders and fleet managers to monitor, upgrade and diagnose their machines, all remotely.”

For its Filter Minder technology, Donaldson Co. Inc. has developed brand new sensing and analytics solutions to enable accurate sensing and monitoring of filter and fluid life. The biggest advancements to date for its air filter monitoring solution have been around enhancing analytics capabilities to help users make better sense of the data that is aggregated says Nate Zambon, Director of Filter Minder at Donaldson. Now the company is focusing its efforts on liquid filter and fluid monitoring, such as for hydraulic filter and hydraulic oil condition monitoring. “Coming up with the intelligence and algorithms [for] fluid condition monitoring is more complex than air filtration monitoring,” says Zambon. Determining end of life for an air filter is a bit simpler because it is basically based off when there is a pressure drop which can be measured by pressure sensors. However, there are a variety of different things that can indicate when oil is at the end of its life or if there are contaminants within it. This requires different combinations of experiments and tests which are needed to validate and characterize oil life cycle, making the development of sensors for doing so more complex, says Zambon. “We’ve really been making a very strong push leveraging Donaldson technology teams, and have some external partnerships that we put in place to support our development of those capabilities within Donaldson, as well as scaling out field testing, because ultimately, in the field is where you prove the viability of the technology,” he says.

challenging for machine builders to acquire. “It is no longer enough to know how to integrate hydraulic components; machine builders need to excel at bringing together mechanical, electrical, electronic and software domains to deliver top performance,” he says. Because of this, Eaton is developing technologies like its Pro-FX portfolio consisting of smart components, controllers and software designed to enable easy integration into machine designs. “By leveraging an open architecture platform, Eaton simplifies the machine control challenge while ensuring the machine builder has the control

and flexibility to differentiate their machines,” he says. Offering a suite of technologies as Eaton and Bosch Rexroth do allows OEMs to get the majority, if not all, necessary components from a single source. This helps ensure components will all work together as needed. It also simplifies and reduces design time. Hershberger notes that as the demand for more intelligence and automation progresses, device reliability and security, as well as machine safety monitoring and software management are challenges which also need to be addressed. “When we start to work in this connected world, no one envisions their machine could be hacked by someone in cyber space, but it is real and your controllers, sensors and connectivity devices need to be protected,” he says. “Imagine in the middle of a software update that the communication link is hacked and the wrong information is loaded on the controller. This could lead to unexpected movement or operation of the machine, or possibly the machine is inoperable and not usable. Additionally, unauthorized connection to the machine that allows for operational parameter changes (POTA) could also cause unexpected operation.” To help overcome these challenges, Hershberger says it is necessary to incorporate hardware security modules into controllers or certify components to certain performance levels. In addition, there must be cloud security and IT infrastructure in place, as well as methodologies to “push” software updates to machines when they are in a safe state. “It is not only the management and transmission of data, it is how that connectivity device and the background infrastructure is put together in what we call device management that is critical,” he says. Machine connectivity and the vast

amount of data that can be collected and transmitted also poses challenges. “Intelligent, useful, big data is expensive and may be cumbersome to manage but ever so important when we talk intelligence,” explains Hershberger. “Therefore, a continuing challenge is one of data compression and filtering out and sending the relevant actionable data.” He says this is key with the connectivity device, and an area Bosch and Bosch Rexroth are working to overcome through the use of Edge Analytics. He adds that the end-user of a machine may be driving the adoption of connectivity and data, but may not be focused on the associated challenges, so it is up to the OEM and solution supplier to be prepared to provide a reliable, robust and state-of-the-art system.

A Pandora’s box of opportunity Hoxie says the recent acceleration of IoT and connectivity is the next step in the ongoing journey towards ever-smarter machines. “Starting from the first electrohydraulic machines decades ago, the industry has been on a continuous journey of ever-more capable machines,” he says. “Over the last decade, we have seen driver-augmented and semi-autonomous agriculture, construction and material handling machines move into the mainstream. Even now, our industry is on the verge of fully autonomous mobile machines.” As such, he says Eaton is ready to help OEMs and their customers embrace the opportunity for continued progress. Hershberger says the ability to connect to machines remotely opens a

“Pandora’s box of opportunity.” This can be seen through fleet management functionalities such as geo-locating and viewing operational data or diagnostics. “With sensors, machine monitoring controller data or critical machine information, the ability to inform the owner of the machine about when a filter needs to be replaced or an indication of a problem on the machine is at their fingertips.” And as technologies continue to advance, so will the intelligence and capabilities built into components and systems. “Instances of upgrades to a machine with flash over the air (FOTA) or changing parameters on the machine to enhance operation for the environment the machine is working in will be commonplace. “The connected machine will become more and more normal,” he concludes. |

nterest in alternative and renewable fuel options continues to increase in the heavy equipment industries as manufacturers and end users look to decrease their environmental footprint. “For years, petroleum-based fuels have been the industry standard, primarily due to the lack of acceptable, cost-effective and reliable alternatives,” says Michael Lefebvre, Manager, Global Marketing Support at John Deere Power Systems (JDPS). “However, with growing interest in sustainable energy, alternative

BOSCH

fuels are becoming more widely adopted and readily available.” While some fuels, like hydrogen, are still in the testing phases, others such as renewable diesel and propane have been used in various capacities for several years and are seeing increased use and application capabilities. The Propane Education & Research Council (PERC), for instance, announced at The Work Truck Show 2020 the development of a Class 8 truck engine capable of running on propane. Propane is often thought of as a fuel for use in lawn mowers or other small equipment. But PERC and manufacturers in the heavy equipment space have been working to increase the applications in which this fuel can be used.

According to Bosch, renewable synthetic fuels can be produced in unlimited quantities unlike biofuels or electricity-based fuels whose supplies can be limited.

Investigating all options Most agree that no one technology or fuel source will be the solution. As such, engine manufacturers and

OEMs are investigating a wide array of options—including hydrogen, propane and natural gas. Cummins Inc., for instance, has announced further partnerships and investments in hydrogen technology in recent months. It also received two U.S. Department of Energy (DOE) awards in August to develop hydrogen fuel cell powertrains. This work is in addition to its development of electric-powered solutions, as well as natural gas and diesel engines. During CONEXPO-CON/AGG 2020, DEUTZ highlighted its various power solutions which included diesel-, gas-, hybrid-, electric-, and hydrogen-based technologies. “From internal combustion engines running on various fuels to hybrids and electric drives, we see ourselves as a development partner and systems integrator,” said Michael Wellenzohn, member of the DEUTZ Board of Management with responsibility for sales, service and marketing in a press release about the company’s presence at the show (read more, 21111055). Alternative fuels play an important

used without the need for expensive and time-consuming modifications. “Firstly, gas-based technologies are well developed and are used in millions of applications. Secondly, there is an extensive and high-capacity infrastructure of existing natural gas networks and storage facilities available, with which fluctuations in the supply of renewable energies can be compensated for, large amounts of energy stored and energy consumption peaks loads absorbed,” says Riegger. “Vehicles powered with gas from renewables, as a supplement to e-mobility, can make a major contribution to the energy transition.”

Synthetic fuels offer possibilities

says there are many benefits available including their ability to be used in today’s infrastructure and engines, as also pointed out by Rolls-Royce. And by making the fuels from renewable sources, they are a more climate-neutral option than some other fuel types. Synthetic fuels can also be used in various applications, including heavy-duty vehicles and equipment. Lefebvre says synthetic fuels could The level of change required to adapt a diesel engine platform to a ClearFlame-enabled engine is similar to those done today for propane or natural gas engines.

role in the wider context of Rolls-Royce Power Systems’ initiatives and its PS2030 – Pioneering Solutions corporate strategy. “The overarching goal of the strategy is to provide answers to the increasing challenges posed by climate change and the rapidly growing societal demands for energy and mobility by pushing decarbonized solutions,” explains Peter Riegger, Vice President Power Lab at RollsRoyce Power Systems. The PS2030 strategy is composed of three main pillars: • strengthening and expanding the core business and expanding Power Systems’ market position; • evolving into a complete solutions provider; • expanding life-cycle services. “The transformation from an engine manufacturer into a provider of integrated solutions has a strong focus on climate-neutral and sustainable solutions which is to be achieved by integrating different renewable energy sources: On the path to net zero emissions, Power Systems is open to all kinds of technologies,” says Riegger. This includes the development of hybrid and full-electric solutions, as well as research into fuel cells and synthetic fuels developed using a Power-to-X process which aims to create fuels from renewable sources (read more, 21082818). The company is currently involved with projects investigating the potential of hydrogen and methane produced from renewables to generate synthetic fuel. Riegger says methane from powerto-gas processes offer numerous benefits compared with other Power-to-X options because the production processes are less complex and deliver significantly higher levels of efficiency, which has a positive impact on production costs. A further benefit is the trouble-free, successive replacement of fossil-based natural gas by compressed or liquid methane from renewable energy sources. This enables existing gas networks and applications to still be

Sometimes referred to as gaseous fuel, synthetic fuel is made from syngas—a mixture of carbon monoxide and hydrogen—created by the gasification of solid feedstocks such as biomass, coal or reformed natural gas. According to Riegger, synthetic fuels are a decisive factor in the energy transition and the use of renewable energies. “Power-to-X fuels may not only replace fossil fuels, they can also be easily stored and transported,” he explains. “With such fuels, we will be able to provide propulsion and power generation on a CO2 neutral basis. These fuels are also an essential element in the urgently needed sector coupling—the close interconnecting of the individual parts of the energy system, such as electricity and mobility, for example, in addition to heating and cooling. We will be electrifying the entire system for propulsion and energy purposes, including the fuel, by producing it with renewable energies in a climate neutral manner.” Bosch also believes synthetic fuels made from renewable sources will be a part of the future fuel mix for mobile applications (read more, 21088254).

be an option for use in John Deere equipment as long they meet current fuel standards such as ASTM D975, EN 590 or EN15940. While it is already possible to make synthetic fuels, there is work yet needed to make them a more viable option for the market. As Bosch points out, making the fuel is still a costly process. It says these fuels will become more affordable

Diesel still has its place Although the amount of fuel options is increasing, “diesel still has a long life ahead,” says Lefebvre. “Even with the growing electrification market, diesel (and diesel engines) will still have a significant role to play,” he continues. “The demands of the off-highway market will continue to remain the same—which requires the energy density that comes from diesel and is not currently available from most alternative fuels.” He says the role of diesel use will likely evolve once smaller applications can meet the same performance requirements with alternative systems. “However, diesel will likely continue to be the main energy source in heavy-duty applications.” Biodiesel and renewable diesel offer customers the ability to still take advantage of the power benefits of diesel while also enabling opportunities to reduce emissions. Lefebvre says among the variety of alternative fuel options currently available, JDPS considers biodiesel and renewable diesel to be the alternative fuels which can be integrated into heavy equipment. “Currently, we believe biodiesel and renewable diesel fuel to be the most viable alternatives to diesel fuel for heavy-duty off-highway engines.” The biggest advantages of biodiesel and renewable diesel is their renewability, says Lefebvre, as they are made from materials such The Natural Gas configuration of the Cursor X concept can provide many of the same benefits as a traditional natural gas engine.

as plants and cooking oils. He notes that pure biodiesel (B100) is nontoxic, biodegradable and suitable for use in sensitive environments. Use of biodiesel and renewable diesel can also result in improved lubricity, zero aromatics and minimal sulfur. Lefebvre says biodiesel also has a favorable energy balance—the difference between the energy produced by 1 kg of fuel and the energy necessary to produce it—of 3.2 to 1. “This means a gallon of biodiesel provides users with 3.2 times the energy it takes to produce it, which is a higher ratio than most alternative fuels,” he explains. Lefebvre also notes that renewable diesel is a hydrocarbon fuel like petroleum diesel, so it can offer many of the same benefits. However, its advantage over petroleum diesel is that it has lower greenhouse gas (GHG) emissions on a well-to-wheels basis. “John Deere recognizes the importance of biofuels to

its customers and to the environment,” he says. “It’s the right thing to do from a long-term economic standpoint, as well as environmental, energy-security and rural-development standpoints.” Riegger says that in the near future, diesel and gas engines may no longer be the sole source of drive and power energy, but they will still play an important role as part of advanced systems technology. “The energy density of batteries is still no match to that of diesel fuel. It is thus unrealistic that the combustion engine will become obsolete in many applications at short notice,” Riegger says. “But as we’ve seen, that doesn’t

mean the combustion engine cannot become decarbonized: synthetic fuels made from captured CO2 with the use of electricity from renewable sources may play a salient role in that regard. “With environmental and climate friendly synthetic Power-to-X fuels, the combustion engine may have a brighter and longer lasting future than many currently expect. We see climate change and the ensuing trend towards decarbonization as [an opportunity] for our MTU technology and continue to offer customers the best solutions in terms of low emissions, fuel consumption, performance and resilience.” |

o experienced equipment operators, compact machines may drum up images of cramped operator environments, minimal comfort features and rudimentary controls. However, manufacturers have been rapidly evolving the operator environment to maximize every inch of available space, while providing features found in much larger machines, such as climate control, pressurized cabs and sophisticated touchpad controls. Compact equipment in particular offers very little space for designers to utilize. “As we design cabs for our compact machines, it’s vital that we utilize every inch of space for maximum

operator comfort and configure operator controls in a way that maximizes functionality in an ergonomic way,” says John Dotto, Wacker Neuson Product Application and Training Specialist. “Wacker Neuson employs engineers with specialties in ergonomic design and it leads us to do things like maximize floor space in our skid steers and compact track loaders (CTL) in order to keep an operator’s feet and legs in an optimal position throughout the work day. Operator comfort has a direct impact on productivity, and the more we utilize the basic principles of ergonomics specific to the type of equipment we build, the greater productivity we can provide our customers.”

As costs have come down for certain HMI products, they are now finding their way into compact equipment. The new generation of equipment operators is also driving operator cab and human machine interface (HMI) designs. Many of them have grown up with video games and smart phones, so they are used to operating multifunctional devices and having everything available at their fingertips. “They are looking for the bells and whistles, the comfort, the ability to be able to easily operate a vehicle,” explains Peter D’Addario, VP of Sales at Carling Technologies. “And they do that based on the types of products they’ve grown up with. So that’s a very important con-

Joysticks are becoming more prominent in heavy equipment cabs to improve comfort and productivity for operators.

sideration when designing equipment.” He says keeping these factors in mind helps to keep the new generation of operators’ attention, enabling them to be more productive, while also helping with employee retention. Comfort is key to operator retention. “Many operators seek the same comfort features they enjoy in their automobile,” says Sarah Peckskamp, Marketing Manager – Loaders, Bobcat. “When we designed the R-Series loaders, we kept this in mind by offering a roomy, sealed and pressurized cab environment with an air-ride seat, heating and cooling options, and eye-level push button controls.” Other automotive-style features include standard keyless start and LED lighting. As manufacturers update their compact machines, the operator environment has become a major point of focus. CASE recently introduced a new lineup of skid steers and CTLs that feature many changes to the operator environment. “These new CASE B Series loaders feature a completely redesigned operator interface, including new left- and right-hand posts with simple ignition, push-button operation, easy throttle control and intuitive switches for all core machine functions,” says George MacIntyre, Product Manager for Compact Equipment, CASE Construction Equipment. Operator-focused designs place an emphasis on ergonomics. “CASE features one of the widest CTL cabs in the

industry, providing excellent space for more comfort and operator positioning,” says MacIntyre. “Joysticks on electrohydraulic models have been designed with a narrower, more comfortable grip, closer switch layout and a smaller head size for easier operation. The electrohydraulic pods on each joystick have also been made smaller to give the operator more legroom inside the machine.”

“This decade will probably be the most disruptive in history when it comes to vehicle architectures,” says D’Addario. This change is being driven by several factors, he says, most notably autonomous driving, connected vehicles, electrification of powertrains and shared mobility, or ACES. Construction equipment—and heavy equipment in general—is also getting smarter. Digitization and connectivity are driving development efforts for OEMs because of the ACES trends in the industry, says D’Addario, which is making its way into compact equipment as well as larger machines. The overall goal with changing vehicle architectures is to provide continuous improvement in uptime, productivity and efficiency. HMI devices are becoming more complex, says D’Addario. There are multiple functions being built into single devices and he says in some cases,

operators are gaining the ability to use them without looking at the device but instead keep their eyes on the task in front of them. Joysticks, keypads and multifunction displays are among the products enabling this which themselves are being enabled by the changing architectures of heavy equipment. “They’re eliminating point-to-point harnessing,” he explains. “If you reduce the points of contact, you’re reducing weight, the amount of wire and connections, and you’re improving the quality and reducing the number of potential failure points. “This is introducing a multiplex network, either CAN, LIN or other device,” he adds. With this multiplex network, it is now easier to connect the vehicle to the internet or the cloud which enables diagnostics capabilities for predictive maintenance. It also enables the introduction of systems like GPS and rearview cameras. Mark Petersen, Global Product Manager for Joysticks at APEM, says the use of joysticks is becoming more prominent in heavy equipment cabs. This is being driven by an increased emphasis on operator efficiency, comfort and safety. “The cab is almost being designed around the joystick,” he says. “As vehicles become more complex, the joysticks are integrating more and more functions to accommodate the

check that they have access to the most current updates. “Wacker Neuson engineers are continuously looking for enhancement and improvement opportunities, which include software updates to machine controls and incab displays,” says Dotto. “Technicians should verify that the latest software is installed when a machine is going through its periodic maintenance to ensure that the machine is running at peak performance. Having the latest software updates allows operators to fine tune settings to suit their preference, level of experience and expectations from the machine.”

More control at an operator’s fingertips There is limited space in an equipment cab and operators need to stay focused on their work. Operators essentially need functionality in their hands, says D’Addario. They want access at their fingertips for the machine functions they need to do most frequently. “So, what we’re doing is applying multiple functions in one device,” he explains. “Before you used to see a single row of rocker switches or row of push button switches all throughout the cab. All these functions are now being combined into a single device, or one or two devices.” This puts everything at an operator’s fingertips and eliminates the need

to search for a button. The operator “knows where that function is and can access it without having to look. It’s much more ergonomic having everything combined in one or two devices,” says D’Addario. As such, he says Carling is continually developing HMI products which can be customized for or in conjunction with an OEM to achieve the goal of placing as many controls as possible at an operator’s fingertips. Listen to our podcast interview with D’Addario to learn more at oemoffhighway.com/ 21197216. Multifunction displays have become more commonplace in equipment as a means of providing functionality in a centralized location and simplifying machine customization. The displays and touchpad controls allow operators to tailor machine operations to match the application and operator preferences. Wacker Neuson provides a wide range of adjustment options on its loaders. “Adjustments that can be made from inside the cab include speed and sensitivity settings to the drive (propulsion), steering and work group (arms and bucket) controls,” says Dotto. “Profile settings can be saved for a specific operator when using a unique log-in code for machines equipped with our 5.7-in. (14.5 cm) color display.” The CASE B Series multifunction display allows operators to make and act on decisions right from the operator seat. “The new display puts all essential information right at the operator’s fingertips—from basic operational information such as engine hours and fluid levels to ‘trip meters’ and utilization data that provide fleet managers and operators greater insight into machine performance,” says MacIntyre. “Electrohydraulic models provide the additional simplicity of switching between ISO and H operating patterns with the simple push of a button.” Being able to adjust machine control settings from inside the cab can bolster operator confidence. “Operators can set total machine responsiveness

needed allows operators to switch from one application or job site to another more easily. People want to get away from single use machines, says Pannone, which is driving design trends for equipment cabs. The company’s new Series 09 CAN Keypad and Rotary Cursor is an example of one such configurable component. It is CAN based (J1939 or CANopen) which allows the operator or the equipment manufacturer to easily configure the operator inputs of the keypad. Typically, it would be more cumbersome to do so, requiring more customized items, says Pannone. Since it is CAN based, there can be a lot of inputs and outputs, and there can be more feedback for the operator—such as illumination behind a button when it has correctly engaged a machine task. Though he notes it is important to not overdo the feedback otherwise it might become distracting. When designing a cab, Pannone says it is important to understand the environment and application in which a piece of equipment will be used, as well as the user. “It’s always a balance between function and intuitiveness,” he says because it is never certain what the skill level may be of the equipment operator.

Operator comfort is a priority Floor space in Wacker Neuson’s compact equipment has been maximized to keep an operator’s feet and legs in an optimal position throughout the work day.

to low, moderate or aggressive, or independently set tilt, lift and drive speed, as well as loader arm and drive control to best meet the demands of the job,” says MacIntyre. “A creep speed feature allows the operator to set machine speed at a consistent/slow ‘creep’ while independently setting attachment speed via the throttle for optimal use of high-capacity hydraulic attachments.” According to John Pannone, VP Sales, HMI Systems/Key Customer Management, North America at EAO, manufacturers’ desire to ensure the flexibility of their machines is driving

the use of multifunction displays and components in operator cabs. This flexibility can be seen in the creation of control panel screens which are configurable, as well as increasing use of displays to provide information to operators. With the increased use of displays, Pannone says devices for cursor control—or navigation on the display screens—are also becoming more common in equipment cabs. All of this is being driven by the fact OEMs want to make their equipment easier to use in various types of applications and environments. Using display screens which can be configured as

Improving comfort is a big area of focus for manufacturers when developing a piece of heavy equipment. In some cases, this means the addition of an enclosed cab on a piece of compact equipment. Better quality seats, infotainment and HVAC systems are also being added. The ultimate goal, says D’Addario, is improving efficiency and uptime, and reducing operator fatigue which helps improve productivity, as well. “To optimize comfort, Wacker Neuson relies on direct customer feedback and input when we design operator stations,” says Dotto. “One of the outputs of this direct feedback loop is seen in the way we design our air conditioning systems. On our newest mini-excavators, the design

of the air conditioning system was an engineering priority with a focus on maximum cold air output in most hot and humid environments. The same is true for all new product development, with a specific focus on cold air with maximum airflow.” HVAC controls have replicated the simplicity of automotive controls. “In addition to traditional climate controls on many of our machines, some newer models offer automotive-style climate control where the operator can set a desired cab temperature,” says Dotto. “The system then works to automatically maintain that temperature.” Designing better cab pressurization systems has also been a priority. Manufacturers are striving to increase the long-term integrity of these systems. “Wacker Neuson skid steer and compact track loader cabs are designed to maintain the best possible air seal over the lifetime of the loader by utilizing a single pod design,” says Dotto. “Essentially, the entire cab is a modular unit that tips for service, floor and all. Cab designs that tip an upper structure only while the cab floor remains integrated in the frame require a seal that can wear out over time, leading to a loss of pressurization that allows dust and pollutants into the operator space. Our ‘pod’-style design eliminates the need for such a seal.” Bobcat R-Series loaders have a new one-piece, sealed and pressurized cab design. “It provides a near-seamless interior for a new level of operator comfort and improved service access,” says Peckskamp. “The roomier design offers a sealed and pressurized environment that repels dust and dirt in the cab, isolates the operator from engine and hydraulic noise, and enhances the efficiency of heating and air conditioning. When it’s time for maintenance or repairs, the entire R-Series cab rotates out of the way to provide improved access, with hardware on the cab exterior for easy removal.” In many cases, operators spend hours in the cab of a compact machine

and it literally becomes their office. “Operators have an expectation of comfort and convenience in the cabs of their machines,” says Dotto. “The cab is essentially a mobile office, so features such as Bluetooth radios and plugs for charging cables are important. It’s also important to have room for storage, a place to secure a phone

and good-sized cup holders. It might sound simple, but sometimes it’s the little things like this that make a big difference to an operator working a long day in a machine.” This article was adapted from one which originally appeared on our sister site at forconstructionpros. com/21136410. |

How Subscription Models Make Businesses More Resilient

RELAYR

Equipment-as-a-Service can provide OEMs with a sustainable business model to increase resiliency.

contributed by Guneet Bedi, Senior Vice President of Global Sales, Business Development, relayr

C

ovid-19 has been a wake-up call for OEMs to enhance their resiliency against unanticipated threats and disruptions. According to an executive report by relayr commissioned with the research firm forsa on the manufacturing industry’s mood, the majority (60%) of industrial companies report being affected by the crisis, and they’re looking for ways to adapt. While the pandemic is an extreme example, there are various ways of dealing with unforeseen crises or fluctuations that will help your business remain stable—or even grow—during times of change or uncertainty. Currently, many of the executives relayr surveyed are taking measures to reduce costs, whether internally or for their customers, ensuring their customer structures are balanced, and looking for opportunities to change business models. The latter is what we’ll focus on today: changing business models. More specifically, on subscription models or equipment-as-a-service (EaaS).

32

What you should know about EaaS In the simplest of terms, EaaS allows you to offer machinery on a pay-peruse basis. It’s taking a business model pioneered by software companies and applying it to heavy-duty industrial machinery. In doing so, your finances become stable and predictable, and your operations become more efficient. In the OEM space, equipment is often costly, yet the price only represents a fraction of the total cost of ownership. The bulk of the cost then comes from support, repairs, maintenance, and value-added services. In fact, more than 75% of the cost of machinery comes from the cost of operations and maintenance of the asset. From an OEM perspective, that means you’re not participating in the most significant percentage of ownership cost. This is especially true if you haven’t invested in advanced technology, like the industrial internet of things (IIoT), artificial intelligence (AI), and predictive analytics, which give you the ability to connect machines and remotely diagnose issues.

On the flip side, your customers are paying a lot of money upfront. And they’re only likely to reach back out to you if something fails or there’s downtime—which is not a scenario conducive to relationship building. Instead, EaaS bridges that gap. The sum of the whole is better for everyone, making EaaS a win/win business model for OEMs and customers alike. As seen in the chart on pg. 33 from Bain & Company, EaaS models help reduce the total cost of ownership for customers, while almost doubling the revenue for OEM businesses. This arrangement also allows more touchpoints with your customers throughout the lifecycle, as opposed to only when things break down.

How subscription models provide a higher level of resiliency The graph from Zuora’s latest Subscription Economy Index™ on pg. 34 shows how resilient companies are those with recurring revenue streams. These subscription-based companies grew their revenues around five times faster than S&P 500 company revenues and U.S.

retail sales during the same period. Why are subscription-based companies so resilient? It’s by design. EaaS allows you to mitigate risks with subscription pricing, recurring revenues, and flexible contracts. Since traditional ownership methods involve

customers buying equipment outright as capital expenditures, it can be 10+ years before they need to purchase another machine. Alternatively, by offering the machinery on a per-use basis, you’ll know precisely the revenue you can expect

during the contract period. For your customers, purchasing usage as an operating expense also comes with beneficial tax implications. EaaS opens up new markets and revenue streams previously unavailable. And by having the ability to

predict revenue, you can better adapt to customer needs by offering more value-added services, aligning your interests, and building genuine partnerships. Take Indiana-based Flanders, for example. The company offers electric motor repair, power systems engineering, custom motor manufacturing, systems integration, and deploys advanced technologies for automation

and autonomous control. However, feedback from customers began showing a similar thread: they didn’t want to be forced into a box. Flanders’ customers wanted to have custom solutions and some flexibility in their contracts to fit their operations. This feedback prompted Flanders to explore digital solutions that could enable a shift toward a predictive service model that reduces downtime and makes maintenance more predictable, giving customers the flexibility they desire while ensuring business outcomes are delivered. For Flanders, this type of business transformation makes revenue more predictable than a traditional break-fix model. Instead of waiting for a machine to break down and a customer to request service—an unpredictable event at best without the right digital tools in place—Flanders can offer

predictive maintenance as a value-add to its pay-per-use model. By predicting machine failures, Flanders can perform maintenance proactively at a scheduled time that eliminates unwanted downtime and increases operational efficiency, a win/ win for both Flanders and its customers.

Overcoming common challenges Over the years of helping customers like Flanders, I’ve come across several common hurdles many face with their business transformations, including: • Waiting until the moment feels right. Industry 4.0 and servitization aren’t new terms in the industry. However, for many OEMs, the value and ROI need to be immediately apparent before they’ll take the leap. Delaying will hold your company back, and you might find compet-

itors are quicker to shift and take your customers along with them. What to do instead: It’s critical that all stakeholders in your business, from IT to operations and sales, are educated in EaaS and how Industry 4.0 plays a role. Finding the right third-party vendor will help this process, ensuring you’re aligned and on the right path. • Only focusing on the end goal. Let’s say you’re planning a cross-country road trip. You’re not going to focus on the engine specs of the car you’re taking. You’ll be thinking more about how comfortable the ride will be and different landmarks you can visit. This is where many companies go wrong when planning for an EaaS business transformation. If you’re too focused on the big audacious goal, you’re likely to lose steam before making it there. What to do instead: I encourage you to think of your transformation like that road trip. What are your stops? What are the milestones and journey points you can celebrate along the way? Breaking your main desired business outcome into smaller goals makes the process more digestible and will keep your momentum going. • Putting the technology first. It’s easy to innovate for the sake of innovation. Focusing too much on the technology or innovation side of a business transformation without context or vision is a sure-fire way to waste time and resources. What to do instead: Incorporating EaaS opens up opportunities for innovation and disruption, but remember to always approach it with the concept of the commercial and business vision in mind.

As the heavy equipment industries currently grapple with an extreme example of the unpredictable, now’s the time to consider creating sustainable and service-based business models to increase resiliency. |

Selecting the right components and materials for hydrogen fuel systems is integral to ensuring performance.

Identifying Unique Hydrogen Fuel Cell System Demands and How to Meet Them Hydrogen has emerged as a promising alternative fuel option but careful consideration must be made in the design and materials selection of critical fuel system components. contributed by Chuck Hayes, Principle Engineer, Swagelock Co.

I

n recent years, hydrogen has emerged as one of the most attractive alternative fuel options for OEMs seeking to dramatically cut emissions from their engines. This is for good reason—hydrogen is a true zero-emissions fuel, emitting only air and water while generating the significant horsepower and torque required in a variety of heavy-duty applications. The technology is evolving rapidly, as governments and industry leaders continue to address some of the barriers to widespread adoption and provide

36

support for OEMs to develop reliable infrastructure and high-performing fuel cell systems. Hydrogen as a fuel source comes with some special considerations that must be made in relation to material selection and specification of critical system components. The systems (see Figure 1) are responsible for on-vehicle hydrogen storage and for converting hydrogen and oxygen to electricity, typically involving a variety of valves, fittings, and tubing. Here, these components must deliver uncompro-

mising, leak-free performance—vehicle and driver safety depend on it. Likewise, the refueling infrastructure that will be necessary for wider adoption must be able to reliably contain and transfer large volumes of hydrogen from storage tanks to the vehicles needing to refuel. The fluid systems involved in performing these tasks are highly important, and they should not be overlooked by OEMs during the design phase of hydrogen vehicles or refueling stations. This article will explore a

few challenges inherent to hydrogen fuel systems in vehicle applications and how to overcome them by selecting high-performing componentry.

Hydrogen embrittlement and material concerns Corrosion is a problem that can plague any metallic system on an on-road vehicle, and it is often exacerbated by a variety of driving and operational considerations. A city bus operating in a snowy North American climate, for example, may have to contend with roads treated by salt or other form of de-icer, which can be harsh on equipment. Hydrogen containment under conditions like these can be especially challenging due to a phenomenon known as hydrogen embrittlement. Because hydrogen molecules are very small, they have the tendency to diffuse into metals, causing them to become brittle. This issue affects traditional 316 stainless steel, which is often used for valves, fittings, and tubing deployed in hydrogen vehicle architecture. This can become a significant problem impacting system performance. The dissolved hydrogen atoms can cause changes in the mechanical properties and behavior of the metal, including reducing its ductility, impact strength, fracture toughness, and resistance to fatigue (see Figure 2). In effect, hydrogen embrittlement may cause lesser grades of stainless steel to act similarly to cast iron—highly brittle and more susceptible to corrosion and cracking. Subjected to sufficient static or cyclic tensile stress, the embrittled stainless steel is at a greater risk of failure. Considering this issue, a hydrogen system that has been designed and constructed with higher-grade stainless steels that are more resistant to embrittlement can be more reliable over the long term. What differentiates a higher performing stainless steel? For example, 316/316L stainless steels that include nickel content between 14 and 30% will show relatively little embrittle-

Higher pressures for hydrogen storage

The pressure at which the gas is stored is another unique consideration for hydrogen transportation. As the technology has advanced, pressures have risen—the higher the pressure, the further the vehicle’s range. Many modern fuel cell vehicles store hydrogen at either 350 or 700 bar (5,000 or 10,200 psi), which is typically dictatFigure 2: Hydrogen embrittlement may cause lesser grades of ed by the needs of the stainless steel to act similarly to cast iron—highly brittle and more application.

met for hydrogen fuel service. The (EC) No 79/2009 EU H2 Regulation in Europe, for example, must be met by any component that is intended to handle compressed hydrogen with a nominal working pressure above 30 bar (435 psi). This includes the 350-bar systems and the higher-pressure 700-bar systems that are becoming more prevalent to meet evolving market demands. For these reasons, it is important that OEMs seek out and specify tubing and tube fittings that meet (EC) No 79 certification for Europe, and HGV3.1 certification for North America.

Operational vibration In addition to their ability to handle high pressures, fittings and connections in hydrogen vehicle applications must be able to withstand constant and repetitive vibration while maintaining their leak tightness. Consider, for example, traditional cone and thread tube and tube fittings that are commonly used in a variety of industrial applications. Ongoing vibration can cause cone and thread fittings to loosen over time, especially since cone and thread connections are made manually. The quality of tube preparation and the finished connection can vary widely depending on the

skill and experience level of the installer. Hydrogen gas is not forgiving of these kinds of imperfections—tiny hydrogen molecules once again can cause potential issues if operational vibrations have caused even the slightest opening in a connection, allowing hydrogen gas to escape through even a miniscule space. Two-ferrule fitting systems can make for a better selection here. A double ferrule design (see Figure 3) can create a twin mechanical grip on system tubing, effectively reducing the likelihood of fittings backing off, even when subjected to continuous operational vibration. This style of tube fitting is additionally less prone to manual installation errors. A new style of two-ferrule fittings that are specifically designed for hydrogen are made by threading a preassembled cartridge (including a nut, two ferrules, and a plastic arbor) onto the fitting body. The tubing is then inserted and marked to establish alignment, and one full turn is applied to complete the connection. After checking with a gap inspection gauge, the fitting is complete and ready for use.

Making the right selections for hydrogen fuel systems In summary, hydrogen fuel systems have unique demands that must be met by each of the components that contribute to reliable, safe operation. Materials must combat hydrogen embrittlement and be able to withstand corrosion; they must be able to contain compressed hydrogen gas at increasingly high pressures to attain higher mileage ranges; and they must be able to withstand continuous operational vibration and maintain leak-tightness at all times. In addition to ensuring the specification of high-performance components that can meet these demands, designers and manufacturers should look to work with component suppliers with considerable, wide-ranging experience in the hydrogen space. Materials science knowledge, along with experience helping OEMs build reliable systems in a variety of gaseous applications, can be a major advantage for organizations seeking to seize new opportunities in the growing hydrogen transportation market. |

n 1951, railroad contractor James L. Allhands (1879-1978) published Tools of the Earthmover Yesterday and Today Preserved in Pictures, likely the first major book written with the intent of educating the general public about construction machinery. One section of this groundbreaking, as it were, work discusses the origins of scrapers, and over the next three issues we’ll see a summary of his material. The scraper was invented as a manually-assisted self-loading and self-dumping device for increased earthmoving efficiency by eliminating shoveling. Allhands traces the scraper’s origin to the stone boat, a stock-drawn sled for transporting rocks dating back to very early Egypt circa 3000 B.C. and used as late as the 1910s. At some point it was surely tried on logs or rollers for friction reduction, then evolved into a cart by adding a wheeled axle. The earliest scraper known to Allhands was the mouldebaert (also rendered as “mollebart” and “mollebaert”), a Flemish horse-drawn agricultural implement resembling a large shovel. The March 26, 1824, issue of American Farmer (Baltimore) explains its operation. The operator manipulated the handle to load it, pressed down to keep the iron cutting edge

clear of the ground for transport, and then dumped the load by releasing the handle, causing the cutting edge to dig in and flip the device over. The handle would end up on the double singletrees by which two horses or mules were hitched to it, and the operator would haul it back to loading position with the attached rope. American Farmer cited an advantage it had over shovels and wheeled carts—it left no ruts to impede the animals. Allhands’ next step in scraper evolution was the drag, or slip, scraper. He also nicknamed it a pig, for its resemblance to a rooting hog. He described this machine as “a sort of glorified stone boat with side-boards” that “extended into a pair of handles at the rear.” He calls it, along with the wagon and cart, “man’s

first practical mule- or horse-powered tool,” and dates its first use in the United States to the Erie Canal in 1825. The first major improvement on scraper design Allhands cites was developed in 1831 by Dudley Marvin of Canandaigua, NY. Marvin raised the scraper’s sides for added capacity, and added iron or steel teeth to the cutting edge and front ends of the sides. This reduced the need for plowing ahead of the scraper, which increased productivity by giving the animals pulling it a better footing. Hybrid designs with iron bottoms and sides and wood backs followed, and Allhands cites the circa 1880 design of S. F. Welch, plant superintendent of Western Wheeled Scraper Company, as the first all-steel scraper. |
