I have never been outside North America, so I am excited about bauma for a lot of reasons. First, getting to see Germany, where my father’s side of the family immigrated from and then settled in Central Alabama, is a life goal. However, being among the en ergy and education during the event will be another goal. Getting to talk with most of the experts and companies that make up our industry is a valuable opportunity. I learn so much when I attend trade shows and conferences. Having the opportunity to travel to bauma and learn with our industry will be tremendous.

Electrification Challenges and Barriers

As if that’s not compelling enough, EVs are also quieter than ICE vehicles. This improves the operating experi ence and reducing noise complaints, which is particularly beneficial for con struction or landscaping equipment used in heavily populated areas.

Ideal Applications

Other commercial vehicle applications well-suited for full electrification. North American school buses, with dedicat ed routes and regular downtime, are an ideal candidate for electrification. Other applications benefit from electri fication as well, including many mining and small construction vehicles. These vehicles shut down at night, which allows for ample charging time and provides improved safety benefits versus their ICE counterparts.

• Public demand for improved sus tainability

In addition to differences in electrifi cation based on industry, location also

• Cost savings

Factors that are influencing this historic move to electrification in commercial vehicles include:

While a passenger car usually has available downtime for charging, many industrial and commercial vehicles are in an almost constant state of use. This makes lengthy charging requirements a barrier to adoption. In addition, heavy batteries reduce the amount of weight that can be hauled or carried. With current technologies, an increase in EV range means a decrease in cargo carry ing ability. However, this is changing as innovations in lighter, more-powerful batteries are expected to be available

• Increased government regulations intended to reduce greenhouse gas

much more challenging. Industrial and commercial vehicle electrification is complex and differs significantly from passenger car electrification.


While EV technology has made huge leaps during the last few years, espe cially in passenger cars, the shift to commercial vehicle electrification is

The business case for commer cial electrification is appealing and improves every day. First, the fewer number of components in electric vehicles (EVs) versus ICEs equates to significantly lower maintenance costs. Second, recent improvements in battery technology are expanding range and improving EV economics. Finally, steeply rising fuel prices make EVs more attractive economically due to their lower cost-per-mile. With these and other factors working in EVs’ favor,

the prediction is that the total cost of ownership of an EV will be lower than that of ICE by 2027 or 2028.

Whenemissionsgovernments mandate lower emissions, companies are driven to adopt new, more sustainable tech

in the future, which will alter EV hauling performance and economics.

Electrification Influencers

For now, hybrid solutions are enabling continuous duty cycles. These config urations are better suited for heavy trucks, construction and other heavy industries. Current battery technology is not advanced enough to be viable for a long-haul truck in North America and many other regions. However, hybrid solutions, including hydrogen fuel-cell technologies, will continue to help in dustries bridge the gap across all appli cations, providing decreased emissions and longer duty-cycle options.

between 2030 and 2040, with EVs becoming the dominant platform across commercial applications.

nologies. That demand also creates economies-of-scale that stimulate innovation and help to reduce the cost of advanced new technologies.

Hybrid Solutions

Compared to passenger cars, the need to move heavier loads across greater distances and for longer periods is driving the development of higher voltage architectures and, con sequently, innovations and engineer ing solutions for commercial vehicles. Commercial EV applications will continue to deliver faster charge times and higher battery capacities to close the financial and performance gaps. Another obstacle to EV adoption in the agricultural industry is the fear of the battery losing charge in a remote location, such as logging in a marshy area. In this example, the weight of the battery is not an issue. However, the worry about accessing a charger is a barrier to acceptance. Also, a current lack of standardization in farming is also an issue.


As OEMs shift to EVs, they face engi neering challenges. A considerable amount of energy is transmitted in EVs, which leads to more complex safety and shielding systems than what is required in an ICE vehicle. Safety, always at the forefront of any vehicle design, demands special at tention in EVs to make sure the user is isolated from the immense stored en ergy. Color coding is not enough. Only qualified technicians should access the high voltage componentry.

Tooperability.facilitatethe transition to EVs in the industrial and commercial sectors, OEMs may want to work with a compo nent supplier that is willing to co-engi neer with them, especially with sensing and connectivity solutions. Partnering with a team to customize solutions and optimize them to each application can be beneficial. A supporting team will work in lock step with the OEMs’ engi neering teams to design, develop and drive efficiency of the total system.

The EV Move Will Continue

During the next five years, commer cial EVs will take off because of contin uous improvements in technology and innovation. |

While the forces driving the transition ing toward electric powertrains are

clear, the path to success is not always straightforward. Operators who want to expand their electric or semi-electric fleet reliably and quickly likely face challenging decisions about the most effective strategy to follow and which partners to work with.

Effective Partnerships

A good place to start is to look at the overall operation to identify specific vehicle use profiles. In doing so, op erators can determine which vehicles and machines would be the best fit to operate with an electric powertrain, hybrid solutions, fuel cells, cables or other methods. They can also talk with equipment manufacturers who have partnerships with powertrain OEMs. To identify the right concept for fossil-free operation, everyone must understand key parameters, such as charging

Sectors such as marine, mining, harbors, airports and construction sites have an opportunity to accelerate decarbonization.


he current, and probably future, price and supply volatility of fossil fuels and the damaging impact of carbon emissions on our planet are compelling companies to switch to sustainable transportation. To reduce energy consumption and emissions in every sphere of the industry is critical for the environment and company profitability.Transporting people, goods and raw materials accounts for more than 25% of the world’s total energy consump tion and almost 30% of global carbon dioxide (CO2) emissions. Diesel-pow ered vehicles also emit other harm ful gases such as sulfur oxides. The technologies to reduce or eliminate these emissions are available now, and


in many cases, they can also improve productivity.Emission-free technologies have been well-established for many years. Over the past decade electric vehicles have grown in popularity in private, as well as commercial use.

Industrial players have an opportu nity to accelerate the shift to sustain able transport in sectors such as in marine, mining, airports and construc tion sites. Emission-free alternatives are available for these sectors. What the industry does will have a rapid ef fect on the environment and can make a difference!

For example, one of Norway’s largest excavator suppliers, Nasta AS, distributes, redesigns and rebuilds construction machinery. The compa ny is collaborating with a powertrain manufacturer to rebuild internal combustion engine (ICE) construction vehicles for electric operation. They used either battery power or a direct cable connection. The conversion pro cedure included retrofitting the diesel vehicle with new powertrain compo nents using electric motors and drives to replace the combustion engine. This new powertrain included an energy storage system and charging solution in place of the fuel tank.

In a vehicle application, the traction converters and electric motors can play a significant role in capturing energy from regenerative braking and feeding it back to the battery or via catena ries to the network. In a traditional combustion engine vehicle, this energy is lost as heat. Regenerative braking systems (RBSs) are already common place in road and rail vehicles, with industrial electric vehicles gradually following suit. |

The driveline must be able to deliver high torque and perform effectively across a range of loads at any time. These are not new requirements for electric motors and converters. They have been doing this job for many years in industrial, rail and marine applications.

Stakeholders need to speed up their global decarbonization efforts to improve the energy efficiency and productivity of mobile equipment. The path for achieving this is clear and available. When operating in the optimum load range, diesel engines only reach a maximum of 45% energy efficiency, as opposed to the consid erably higher 95% efficiency of an emission-free electric driveline.

To successfully address the rapid and widespread transi tion to ZEVs, the industry may primarily rely on major origi nal equipment manufacturers (OEMs) and their suppliers for the solutions.

From the Inside Looking out

The responses to these relevant questions drive most commercial vehicle and heavy-equipment purchases. Getting new technologies operational, appropriately certified, into production at scale and then to deliver a product that functions in the real world as advertised is a tall order for any organiza tion, particularly one new to an industry.

“While landscapers and turf managers have had electric options ... for years, ful ly electric, battery-powered construction equipment like compact wheel loaders and excavators are new,” said Lars Ar nold, electromobility product manager, Volvo Construction Equipment.

Battery power, digitalization and efficiency drive these industries.

OEM Off-Highway recently spoke to Sara Webb, editor, Green Industry Pros, about lawn and landscape, commonly called the “green industry,” trends.

some landscapers are taking a fresh look at robotic equipment and software to streamline and automate tedious processes they already had in place. It will be interesting to see how manufac turers answer the calls for new efficient products, particularly at this year’s Equip Expo in Louisville, Kentucky.” Webb said other trends include:

One popular buzzword in the green industries and construction is electri fication, and with good reason. Both industries are in a transformation in power sources. The electrification of passenger and smaller mobile com mercial vehicles is occurring rapidly.

According to Nick Moore, director of sales—electrification, at Briggs & Stratton, green industry professionals realize how important battery-pow ered equipment is.


“Most green industry profession als I speak to are looking for ways to up their efficiency—labor efficiency, equipment efficiency, energy efficiency, water efficiency,” Webb said. “You name it; they’re striving for it. To that aim,

According to Moore. “The battery features an exchangeable design, allowing customers to easily remove and replace the battery with minimal downtime. The Swappable Battery also enables [scalable] power, so you can use [multiple battery packs] to meet larger power needs.”

“We are closely working with OEMs, ... to help them be successful in a world with changing demands,” Moore said. “Wherever the industry takes us, we’ll be there to support OEMs and their customers in navigating these changes.”|

Vanguard also helped custom ers with electrification. “Earlier this year, Scag Power Equipment (Scag) introduced its EVZ electric zero turn riding mower (see Image 2), which is powered by the Vanguard 5 kWh com mercial lithium-ion battery pack,” said Moore. “The EVZ is the first fully-elec tric unit in Scag’s lawn mower lineup. We were excited to work alongside Scag to bring a new battery-powered option to the turf market.”

“When it comes to the benefits of battery power, the output of zero emissions is a huge regulatory driver for OEMs and end users,” Moore said. “However, battery-powered equipment can also offer a better user experience because of its quieter operation and minimal required maintenance. Anoth er big driver is mitigating the cost of fuel. For professional cutters who must fuel up an entire trailer full of equip ment every day, battery power can really benefit the bottom line of their business given current gas prices.”

To add to the efficiency of using battery power, Vanguard developed a swappable battery, borrowing from smaller batteries used in power tools and small outdoor power products.

Component suppliers are eager to help OEMs meet their customers’ needs.

The construction industry will face dis ruption in the upcoming decades that will be driven by 4 highly disruptive trends:

Supporting OEMs on the Journey

According to Moore, “Another big trend we’ve seen is that many man ufacturers, including Vanguard, are turning ... to developing and designing engine (or power-source) features that help enhance productivity and reduce maintenance requirements.

“With labor shortages and a pent-up demand of lawn and landscape work, the industry is being asked to do more with less. Professionals are relying on their equipment ... to deliver a powerful performance and maximize productivity.”Decreasedwait time to get started is also an increase in efficiency. “Electric machines provide instant torque, so there is no delay like you might feel on a diesel machine,” said Arnold. “In ad dition, the maintenance is much easier (and less expensive) because you don’t have an internal combustion engine to take care of.”

“One of the first U.S. projects our ECR25 electric compact excavator and L25 electric compact wheel loader were used on was building a trail at a national wildlife refuge,” Arnold said. “The quiet operation was less of a disturbance to the animals living in the area, and the lack of emissions was safer for the environment.”

the machine to “know” where it is.

How GPS and Other Tech Boost Productivity and Safety

machines will know how far to dig no matter where they are located on that site.Some GPS software allows operators to create layers, as well. Suppose you’re putting in a water line that involves multiple material layers with specific requirements for each. Let’s say you want 6 inches of sand as your base, 3.5 feet of gravel, 2 feet of fill soil and then 1 foot of topsoil. Having a screen show exactly where you



Machine control is now widely used on excavators and dozers, but systems that support GPS can take things to another level for digging accuracy and more complicated shapes. Typically, in ertial measurement unit (IMU) sensors are mounted to certain parts of a ma chine and can tell the operator where the bucket tooth is and therefore, how close they are to a target depth or grade. Upgrades can include satellite antennas and smart receivers, which make up GPS functionality and allow

A jobsite map


How GPS Can Help

For example, on an excavator, the operator can use an in-cab interface (like a tablet) to draw the shape he or she wants to dig. Let’s say it’s a basement. Then he or she can put the bucket on the ground where one cor ner of the basement will be, move the bucket to a second spot and that tells the machine to “draw” a wall between the two. Depth and slope can be factored in, as well. Thanks to sensors and satellite receivers, the machine will remember where every point is as it Upgradingmoves.to3D software like Trimble or Topcon takes GPS support one step further. These programs can import a computer-aid ed-design (CAD) file for an entire jobsite, such as the roads, water and sewer lines for a housing subdi vision. All GPS-equipped

sing GPS functionality on construction equipment to automate tasks is becoming more common, and some OEMs have made these features stan dard on new equipment. Though many owners and operators are getting more comfortable with—and even depen dent upon—technology to help them be more productive, some may still need a little help making sense of it all.

An operator responds to coaching VOLVO CONSTRUCTION EQUIPMENT

Another safety-boosting feature supported by sensors and electro-hy draulic technology is swing control, also known as swing fencing. An operator can create what is basically an invisible “wall” so they cannot swing into traffic, other machines or people. The machine will remember where the wall is and stop itself from breaking it. Similarly, height or depth limits can be set to avoid hitting objects or clipping utilities, for example. Object detection is beginning to find its way into the market, as well, which will do exactly what it says and alert operators when something is in the way.


a given site can see where the others are, helping operators avoid traffic and safety concerns and improving jobsite (and fuel) efficiency. For mapping to take hold in the industry, better jobsite connectivity will be needed so data can more easily be shared between machines in real time.

Many compactors and pavers also have assistive technologies that allow operators to see how many passes they’ve made, the temperature of the material, its density and other important data that can improve their productivity.Advancements are happening quickly in the realm of automation. Some OEMs have semi-autonomous machines on the market, and some are working on fully autonomous versions. The automated features on today’s ma

are will make that work much easier and faster, preventing rework and min imizing the danger of having a person in the trench measuring depths.

Some articulated trucks and wheel loaders come with a speed limiter option that automatically regulates maximum speed. If you’re in a region that sets speed limits on worksites,

Automating certain tasks can improve efficiency even more. To give another excavator example, many systems will “cut grade” on the final pass. But with automation technology, the oper ator will control only the arm while the computer will control the boom and bucket to ensure the last pass is smooth and at the right depth.

Additional Interface Features

Assistive technology (not GPS-related) can also help the operator make re al-time adjustments to boost efficiency. Coaching tools can identify and alert operators of trends in idling, brak ing, accelerating, fuel consumption, improper work modes and more. The operator can choose to adjust their be havior accordingly or ignore the alerts, so keep in mind that a machine is never more efficient than its operator.

the boom stop at a predetermined point while lifting, which is especially helpful when loading a truck at the same height for an extended period. Return-to-dig stops the boom while lowering, helping the operator return the bucket to the same position every time so it’s ready to dig again. When these functions aren’t done properly, you’ll see the machine bucking or even getting stuck, which disrupts the cycle and wears down the tires and machine.

One of the most popular automated tools is on-board weighing. Not every worksite can have a scale handy, and even if they did, it could slow things down. If a machine can weigh its load on its own, operators can skip adding or dumping material and reweighing, saving lots of time and fuel. Over loading can also increase wear on a machine and lead to overweight fines.

ten have work modes like fine, general and heavy, and wheel loaders may have response modes like soft, active and normal. These can adjust things like engine rpms, hydraulic lever sensitivity and fuel consumption. Some operators think working in the highest mode possible is the way to go, but that isn’t always the case and it isn’t the best use of your machine or fuel. Running 200 to 300 rpms lower can equate to a 10% re duction in fuel use on many machines. Less rework means better productivity and higher profits, so don’t let a fear of the unknown keep you away. |

A range of positioning hinges with built-in technology allows displays to be moved with one hand yet avoid shaking from engine or equipment

by Bob Straka

This is changing the cab into a mobile office, where an operator may be responsible for a wider range of project duties, like managing sched ules and other supervisory activities. It is also evolving the layout and systems being installed in the cab, like comput ers for planning and scheduling and other digital devices. This increases the number of screens that need to be securely mounted but easily adjusted to accommodate different tasks.


The use of positioning technology with intuitive touch point characteris tics can be useful in these applications. Hinges can offer integrated, con stant-torque-enabled, single-handed ad justment of connected monitors. Leading device suppliers offer hinges engineered for the higher levels of vibration found in the rougher operating environments of off-highwayConstant-torqueapplications.hinges use engi neered friction to provide a specific resistance against motion. They enable positioning of a cab operator screen at any angle for thousands of operating cycles, without any degradation of torque—even under high vibration conditions. Even with this resistance against motion, repositioning is easy.

An equipment operator can move a screen to a better angle with one hand while safely driving the vehicle or oper ating the equipment.

“Autonomous” operation in many off-highway applications is growing: more and more equipment can be pro grammed to automate functions that include digging a trench or spraying a field with herbicides. This requires an operator inside the cab to oversee its operations and perform other tasks while keeping an eye on the equip ment as the job is completed.

An EAS platform makes it easy for equipment manufacturers to include automatic unlocking in their machines, giving fleet operators improved security and efficient audit trail management.

Users of off-highway equipment want the comfort and convenience found in modern automobiles in a rugged and durable package. Well-en gineered access hardware, such as hidden latches and electronic locks, can help improve vehicle designs and the user experience. The same impression results from panel latches and entry door hardware that reduc es noise by eliminating rattles and operating smoothly and reliably with gloved hands.

they experience sudden stops or im pact situations.

Common practice in many agricul tural and construction applications is to leave equipment onsite over night rather than return it to secure storage areas every day. In addition, when different personnel operate the equipment, especially with rent ed assets, operators will be assigned to different machines every day.

A major and ongoing challenge for off-highway equipment owners and operators is security. Protecting ex pensive equipment from vandalism or break-in attempts to steal the vehicle or parts is a growing priority.

Electronic locks can incorporate proximity detectors that automatically unlock a door or storage compartment on an off-highway vehicle when an operator climbs up to enter a cab or approaches a locker. This helps improve operator safety, eliminating the need to dig out and actuate a key fob if their hands are full or holding on to a ladder.

One way that access and position control suppliers can help OEMS control costs is by providing products that have been tested and certified compliant with regulations such as the U.S. Federal Motor Vehicle Safety Stan dards. These standards are designed to ensure that products such as position control hinges or latching systems function securely and do not fail when

While some off-highway equipment manufacturers are building electron ic access and control into their own vehicle control modules, electronic access solutions (EAS) platforms avail able from access and position control providers can simplify the process of incorporating EAS into vehicle designs. These EAS platforms have electronic locks with wireless interfaces, such as Bluetooth, so an operator’s digital device—typically a smartphone—can act as the “key.” Operators will have an EAS app on their device, to which time-based virtual keys can be sent via a cloud-based portal, simplifying the assignment of keys to multiple users and different pieces of equipment. That way, instead of having to distrib ute, manage and track the location of key fobs or other physical access devices, the process can be controlled virtually, which can be especially useful for equipment rental operations.

How R-1234yf Solves EV Comfort and Range Challenges

Initial EV Heating Technology

energy the heating system requires to maintain a comfortable cabin tempera ture. Lastly, the harder a battery works, the less durable it becomes. So, as “range anxiety” crept into the psyche of EV operators, electric-resistive heaters were in the hot seat.

With EVs quickly transitioning from the vehicle of the future to the vehicle for today, new trends are emerging to support manufacturer and regulatory goals by Adam Kimmel


The concerns with these heaters are valid. According to AAA, driving and using an EV’s heater at or below 20°F can decrease the average range by 41%. In off-highway EVs, chal lenges of electric-resistive heating become steeper, because the battery is tasked with fueling bigger systems, and in many off-road applications, recharging options are limited. A few years ago, this publication partnered in gathering viewpoints from OEMs about the future of off-road EVs, which revealed battery power as the biggest challenge to going electric. Reserving

ith about 2.5 million electric vehicles (EVs) on U.S. roads and U.S. sales doubling from 2020 to 2021, EVs have evolved past being only a purchase for highly eco-conscious early adopters. A similar dynamic can be seen off-highway, which is expected to experience a substantial 21.5% compound annual growth rate between 2021 and 2030. With EVs quickly transitioning from the vehicle of the future to the vehicle for today, new trends are emerging to support manufacturer and regulatory goals of making EVs increasingly acceptable, accessible and attractive for a growing number of individuals and industries.

High on the list is thermal manage ment, specifically improving cabin comfort without contributing to “range anxiety.” At the heart of this solution,

To prove the concept that heating and cooling could work successfully in all-electric plug-in and hybrid vehi cles, engineers equipped the first EVs with electric-resistive heaters using a positive temperature coefficient (PTC) heating element. This approach did what needed to be done, plus building the system into the vehicle was con venient, parts were available and the overall complexity level was low. How ever, electric-resistive heaters create heat from battery energy, negatively impacting vehicle range. Moreover, the colder the ambient air, the more

The option quickly gained favor, especially among European manufac turers like Jaguar, BMW and Volkswa gen. Today, more and more EVs are factory-designed with heat pumps.

, AGRO has developed a completely new type of EMC cable gland, precisely tailored to the

cabin for warmth or removing heat from the cabin to cool it. Heat pumps are highly attractive for EVs because they utilize an endless reserve of “free” source energy from outside air, instead of battery energy. They generate up to three units of heat for every one unit of energy consumed, compared with a PTC’s one-to-one output. In addition, heat pumps work both ways to heat and cool, and may help extend a bat tery’s durability by putting less work on the battery.

Today, R-1234yf—the same refriger ant quickly overtaking automotive manufacturing and aftermarket as the refrigerant of choice for air condi tioning systems in other types of vehicles—is dominating the EV space as the preferred refrigerant for heat pumps.

The heat pump solution is here to stay for EV cabin comfort. And for the reasons above, R-1234yf offers the best solution for heat pump thermal management. However, best is not perfect. The indus try is very close to introducing refrig erant blends that use R-1234yf as the ideal base. These optimized blends will augment R-1234yf with other materials to further improve performance and efficiency and potentially allow for heat pump systems with fewer components and lighter weights. Scientists are also in the lab to innovate formulations that could take refrigerant GWPs even lower.

Carbon dioxide (CO2) remains a popular refrigerant choice for EV heat pumps, but it has several challenges that R-1234yf addresses. Because CO2 has a low critical temperature, it needs to operate at high pressures, requiring a unique compressor, special components, and a great deal of metal around a small channel to contain that pressure. All these translate into a heavier system, and weight costs an EV in driving range. In addition, CO2 requires more complex maintenance and the hazard of operating a vehicle containing a refrigerant under high pressure. Moreover, R-1234yf covers more of the cabin comfort temperature range than CO2, which operates poorly at temperatures above 32°F. Chemists and refrigerant innovators appreciate CO2’s environmental advantages (it sets the baseline of the GWP scale), but its technical and safety challenges

people make the switch to EVs. And as more of these vehicles appear on and off the highway, governments will keep a close eye on the environmental im pact of refrigerants. The same regulatory landscape—namely the European tran sition away from R-134a use in light-du ty vehicles and similar regulations from the U.S. EPA—has resulted in 80 million R-1234yf-charged vehicles being driven on U.S. roads, nearly 30 manufacturers adopting it for gas-powered vehicles, and it is coming into play for EVs. We can expect to see an exponential increase in heat pumps that utilize zero-ODP, lowGWP R-1234yf and R-1234yf blends to support sustainability initiatives. |

Never has this been truer than with fasteners in the off-highway mobile equipment manufacturing sector.

From diesel and electric engines to hydraulic systems to electrical compo nents, supply chain disruptions have made providing the equipment that customers want difficult. While fasten ers may seem to be a small part of the overall manufactured product, they are especially important components in off-highway machines.

how a fastener supplier reduces risk is important. One of the first factors to determine is availability. What is the availability of parts, and how does the supplier manage inventory? What is the proximity of distribution centers to see if delivery times can be shortened? What is a supplier’s record of on-time delivery in respect to these regional sourcing capabilities?

Using two engines created a prob lem in synchronizing the engines, and the torque converter solved this by automatically compensating for minor variations in load on the transmission such as were imparted by two unsyn chronized engines. The operator could shift both transmissions simultaneous ly with a single lever.

After two years of experimentation, the first twin-power machine was an 18-cubic-yard capacity bottom dump truck introduced in 1948. The first twin-power scraper followed in 1949. Both machines had one engine, a transmission in the tractor to power its drive axle, and a second on the back to power the wagon or trailer. This gave them increased capacity and mobility when compared to their single-engine counterparts. The scraper had the additional advantage of not requiring a push tractor for loading except under the most severe conditions.


Euclid owed the success of twin power to the development of the Allison Torqmatic transmission in the mid-1940s. The transmission was semi automatic, with full power shift and a torque converter. These features made it possible to shift instantaneously under full power and load.


ne of the Euclid Road Machinery Company’s major innovations was the twin-power con cept. The basis of the concept was powering each drive axle of a truck or scraper with its own diesel engine and powertrain. The idea is believed to have originated with the Koehring Company, which used twin, diesel engines and powertrains to propel a short-lived crawler version of its Dumptor shuttle dump truck in the 1930s. However, Euclid was the first to use it successfully.

Image 1. A Euclid TDT series twinpower scraper’s extra power helped it take a healthy load of clay on the Massachusetts Turnpike in 1956.


Twin-power was also applied to a line of massive, end dump trucks and the famous TC-12 crawler tractor. The end dump trucks were among the largest available in the 1950s and early 1960s. The TC-12 was the largest and most powerful crawler tractor from its 1955 introduction until Fiat-Allis unveiled the HD41. The TC-12 rode on two frame halves that oscillated against each other on rough ground and could be unbolted for transport. For all its power, it was also the most complicated crawler on the market and was prone to expen sive mechanical issues |
