Volvo Construction Equipment

Volvo Group has taken a leading industry position in the transition to electrification, currently offering electric vehicles and equipment ranging from city buses and trucks for construction, waste management and urban distribution, to compact excavators and loaders. Most recently, the company announced exploration into the mid-size construction equipment market with its prototype model EX03 electric wheeled excavator. The company indicates it will roll out further electric vehicles and related services at a high pace – including heavy-duty trucks for regional transport or construction, later this year.

As it continues its drive toward a more electric future, the company has formed a new business area dedicated to accelerating electrification. Volvo Energy will have an internal role in providing batteries and charging solutions to Volvo Group’s other business areas, as well as an external role offering used, remanufactured and refurbished batteries to customers for use across various applications. The intent is for Volvo Energy to strengthen the group’s business flow of batteries over their life cycle, while expanding the offering of charging infrastructure to customers. It will also help to limit the environmental impact from electric and hybrid electric commercial vehicles and machines by giving used batteries a second life.


Volvo's Mid-sized Electric Wheeled Excavator Moves Electromobility Goals to a Larger Size Class

The EX03 mid-sized wheeled excavator prototype represents the next stage in the electromobility journey for Volvo Construction Equipment.

For the past few years, Volvo Construction Equipment (Volvo CE) has been on a path toward increased electrification of its product lineup, as it showcased various concept and prototype models and their extensive testing on active jobsites. In 2019, the company announced its intent to launch a range of electric compact excavators and wheel loadersby mid-2020, ending new diesel engine-based development of these models.

True to its word, by August 2020, Volvo CE was prebooking orders in North America for the ECR25 electric excavator and L25 electric wheel loader. In December, the first delivery of an electric ECR25 to a customer occurred in France, with deliveries anticipated to begin in North America by mid-2021.

As the next stage in its electromobility journey, Volvo CE has now unveiled the EX03, its first electric prototype in the mid-size excavator class.

“This prototype is a significant step forward in the evolution of medium electric construction machines,” stated Inwoo Kim, program manager for Advanced Engineering at Volvo CE. “As our first electric excavator concept in the mid-size range, we have been quick to build and expand on our existing electromobility technology.”

The EX03 “represents the future for safer and more environmentally responsible construction sites,” the company states, and follows on the technology and product design iterations of the fully electric EX02 concept electric excavator. The 14-ton EX03 is equipped with a battery pack from Volvo Trucks and boasts the same performance level as a diesel machine in the same class.

According to Volvo CE, the electric prototype – the latest development from the Volvo Concept Lab – aims to deliver zero emissions, higher efficiency, lower noise levels and reduced total cost of ownership compared to its conventional counterparts. One of the unique features built into the concept model is a video screen on the back of the machine that offers three configurations:

  1. A real-time video stream from the front of the machine, allowing vehicles behind it to clearly see ahead when driving on public highways.
  2. A text-based safety screen alerting workers on site to left and right movement or reversing.
  3. A safety communication livestream enabling the operator to make eye contact with pedestrians and workers, minimizing misunderstandings and increasing safety.






Volvo CE plans to test a similar version of the EX03 in customer pilots, but indicated that the model is in the concept stage with no current no plans to bring it to market.

Proterra Collaborating with Komatsu on Electric Excavator

Proterra will provide its battery technology for use in a proof-of-concept battery-electric hydraulic excavator Komatsu plans to bring to market by 2023.

Proterra announces it has signed an agreement with Komatsu to provide battery technology for development of a Komatsu battery-electric hydraulic excavator. According to Proterra's press release announcing the collaboration, this is the first time the company has been involved with a project in the off-highway equipment industry. It will also be the first piece of construction equipment powered by Proterra batteries.

Komatsu intends to use Proterra battery systems to create a proof-of-concept middle-class electric excavator in 2021, with commercial production planned in 2023-2024. High energy density batteries and fast charging technology will be used for the excavator.


Proterra says in its press release that its battery packs offer high energy density and a customizable design which can suit the needs of various vehicle applications. This packaging flexibility will allow Komatsu to optimally place the batteries in the middle of the excavator and replace the need for a counterweight.

The company introduced its H Series battery pack technology in September 2020 which has a more narrow design for easier installation. This battery joined the company's S Series which also offers design flexibility for customers. Both battery models feature modules which can be produced at four different voltage ratings to meet an OEM's specific design needs.

Proterra's batteries use NCM 811 lithium-ion cylindrical cells and can support vehicle voltages up to 1,200V DC and 6 Mwh in size. Various safety features are included, as well, to ensure reliability and durability.

"As more communities embrace a zero-emission future, Proterra is excited to partner with Komatsu to develop battery-electric construction equipment," said Proterra CEO Jack Allen in the Proterra's press release announcing the collaboration. "Proterra’s best-in-class battery technology has been proven in 16 million miles driven by our fleet of transit vehicles. What’s working in our battery-electric transit vehicles on roads across North America can work off-road, too. We look forward to collaborating with Komatsu to deliver the benefits of emissions free, quiet Proterra Powered vehicles to more communities around the world."



"I am excited about the collaboration with Proterra, by which Komatsu will drive the electrification of construction equipment," said Seiichi Fuchita, President, Development Division, Komatsu Ltd.

JCB Expands Electric Machine Offering for Zero-Emissions Operations

New additions to the company’s line of electric machines help customers stay productive while meeting sustainability initiatives.

In late 2020, JCB announced the expansion of its E-TECH range of zero-emissions vehicles. This included the launch of the company’s first electric Loadall telescopic handler, a new electric site dumper, as well as offering a fully glazed cab on the 19C-IE electric mini excavator. In addition, JCB has developed a new rapid Universal Charger which is compatible with current and future E-TECH electric machines.
f853f9c5.601073a558996.6010750f75827.6010753a5cb9c.jpg

The new Universal Charger can charge the 19C-1E electric mini excavator in 2 1/2 hours.

“The pace of change is rapid, and we need to be equally quick in responding to the growing environmental challenge posed by climate change and the need to improve air quality,” said Tim Burnhope, Chief Innovation Officer at JCB, during the company’s virtual launch event for the new products. As such, the company has placed an emphasis on developing clean technologies in the form of electric-powered equipment and near zero-emission diesel engines.

New electric telescopic handler

JCB’s new 525-60E all-electric Loadall telescopic handler — called the 505-20E for customers in North America — is designed to provide zero-emissions operation in construction and agriculture applications. The electric machine looks similar to its diesel counterpart, and is just as powerful and productive, said Richard Brooks, Engineering Director for JCB’s Material Handling and Access Product Group, during the launch event.
JCB_virtual_press_conference__3_.601079876d447.png
A 96V lithium-ion battery is used in place of a diesel engine in the 525-60E and provides full-shift operation.

A 96V lithium-ion battery is used in place of a diesel engine in the new 525-60E and provides full-shift operation. Use of a lithium-ion battery enables quick, clean, maintenance-free charging using either an onboard charger or JCB’s new off-board rapid Universal Charger said Brooks. The Universal Charger can fully charge the telescopic handler’s battery to 100% in 60 minutes.

Top-off charging also occurs during machine operation via a regenerative braking system. According to Brooks, the robust battery can be charged over 5,000 times which is the equivalent of 10 years of use in typical duty cycles. The battery is also capable of operating in temperature ranges from -20-60 C (-4-140 F), enabling it to be used in various locations around the world.

A motor controller converts the battery’s direct current into alternating current to power the 17-kW (23-hp) transmission system motor and 22-kW (30-hp) hydraulic system motor. It manages electric power demand from the transmission and hydraulic systems to ensure optimal machine performance. The motor controller balances acceleration, deceleration and hydraulic control while loading, placing and transporting goods, said Brooks.

For the driveline of the 525-60E, JCB has replaced the hydrostatic drive components used in the diesel version with new, highly efficient electric motors. “The 17-kW drive motor is connected to the front and rear JCB axles that have been developed to be as efficient as possible, whilst maintaining the strength and durability of those on the diesel-powered machine,” said Brooks.

A new hydraulics system was developed for the electric machine, as well. Its 22-kW motor powers an efficient, low noise internal gear pump to provide the same flow and pressure as the diesel machine. Brooks noted that hydraulic flow is not linked to engine rpm; joystick position alone determines the flow and speed of operation.

JCB’s new 525-60E all-electric Loadall telescopic handler provides the same performance as its diesel counterpart.JCB

Smart, regenerative hydraulics capture and store energy when lowering and retracting the boom. This energy can be used by the battery, extending the amount of time the machine can work before needing to be recharged.

The 525-60E provides a maximum lift capacity of 2,500 kg, and maximum load of 2,000 kg at its full lift height of 6 m. For the North American version, this would equate to a maximum lift capacity of 5,500 lbs. and a maximum lift height of 20 ft.

Zero-emissions and low-noise operation capabilities make the telescopic handler suited for use in both indoor and outdoor operations, including noise sensitive job sites.

Additional electric site dumpers now available
In mid-2020, JCB introduced the HTD-5e E-Dumpster. The all-electric walk-behind dumpster can carry up to 500 kg (1,102.3 lbs.) and is powered by a 48V lithium-ion battery. Its 9-kW (12.1-hp) motor delivers travel speeds up to 3 kph (1.9 mph).
l_press_conference__7_.6010783a5635b.601078e553e30.png
During its virtual launch event in November, the company announced the release of a larger electric site dumper, the JCB 1TE. It is designed to work indoors, underground and in other emissions-sensitive areas. “It's an ideal partner for our 19C-1E electric mini excavator,” said Andy Whyman, Group Engineering Director at JCB. “It's a high tip dumper with a full-size steel skin that has a maximum load over height of nearly 2.4 m (7.9 ft.).”

He noted it is a durable machine with a heavy-duty articulated chassis which can handle a maximum payload of 1 metric ton (1.1 U.S. ton). Use of drive axles and a dropbox instead of hydrostatic drive motors enables the new site dumper to provide continuous all-wheel drive, aiding mobility and thus productivity on job sites.

Two 5 kWh lithium-ion batteries power the machine. A 7-kW (9.4-hp) hydraulic motor delivers drive power to the dropbox while a second hydraulic pump powers the hydraulic circuits for steering and lifting.

Enclosed cab for mini excavator expands market use
JCB first introduced its 19C-1E fully electric mini excavator in 2018 which then went into full production in 2019.

The electric mini excavator is five times quieter than its diesel counterpart, said Whyman. It now comes with four next-generation lithium-ion battery packs, ensuring energy capacity of 20 kWh. This provides not only a full day of work but also additional electric power where needed such as for systems in the cab.

avator_1.600f1fff314ad.601073b1d2546.60107485c403e.png
A new, fully enclosed cab on the 19C-1E is ROPS/FOPS certified to ensure the safety of operators.JCBThe new, more spacious cab JCB has introduced for the 19C-1E provides instant heat to rapidly defrost the windows and keep operators warm. This makes the machine well suited for use in colder, wetter climates said Whyman. “We see plenty of opportunities for this machine in Northern Europe, North America and in Scandinavia where electric solutions are already in high demand,” he said.

Power consumption is managed to ensure heating the cab while also guaranteeing optimal machine operation. “When operating on its maximum setting, the heater only draws on half of the power from one battery,” explained Whyman. “There is no impact on digging or tracking power when the heater is in use.” This is because machine operations only draw power from the remaining battery energy not used by the heater.

The new cab is ROPS/FOPS (Roll-Over Protective Structures/Falling-Object Protective Structures) certified and equipped with easy-to-replace laminated flat glass. It ensures optimal visibility with its 70/30 front windshield split and clear jointing which prevents the digging area from being obstructed. A clear view around the entire machine is provided, as well, further aiding visibility.

LED working lights and wipers like those used on diesel models are included to aid visibility in poor working conditions or at night.

Charging is an integral part of the equation
The new high-powered Universal Charger was developed to provide a single rapid charge solution for all JCB electric machines in a customer’s fleet, said Bob Womersley, Director of Product Innovation at JCB, during the virtual launch event. It works with electrical systems from 48-96V and above.

This new off-board charger can be easily installed at any site offering 480V three-phase electrical supply. It comes with both four- and five-pin electric connectors for use across Europe. The charger will also be made available to customers in North America and other parts of the world.

According to Bob Womersley, Director of Product Innovation, the high-powered Universal Charger was developed to provide a single rapid charge solution for all JCB electric machines in a customer’s fleet.Womersley said all JCB electric machines come factory supplied with a standard built-in charger, as well as preparation for use of the new universal charger. “You simply plug your machine into the Universal Charger for a high-speed boost during the workday,” he said. This ensures the piece of equipment will continue running and meeting the productivity needs of the job site.

Fully charging the 19C-1E mini excavator with the Universal Charger takes just 2-1/2 hours, enabling job sites to stay productive said Womersley.

For customers who do not have a three-phase electrical supply on their job site, JCB has launched a new range of power packs to support the growing line of electric machines. They provide zero-emissions, silent electrical backup to remote job sites or those not connected to the electrical grid. Womersley said the power packs will come with four or eight robust, JCB proven batteries. He said they are beneficial for not only power JCB machines but also general backup power for job sites. They can also be paired with, as well as recharged by, a JCB generator being utilized on site if necessary.

Development of the new charger and the electric machines are part of JCB’s Road to Zero Program through which it is looking to offer 100% electric, zero-emissions machines to meet a range of customer application needs. Burnhope said there is a lot more to come from JCB regarding electrification developments, as well as other emissions-reduction technologies such as alternative fuel options.

“We've come a long way in a short period of time, and we are fixated on accelerating our next steps on this road to zero,” he concluded. “We won’t wait around. We know there’s much more to do and we are getting on with it.”

Navistar, GM Part of Group Launching Hydrogen Truck Ecosystem


Navistar-Hydrogen.jpg

In collaboration with General Motors and OneH2, Navistar is introducing a complete solution for customer implementation of a zero-emission long-haul system, which will be initially piloted by J.B. Hunt Transport.
"Hydrogen fuel cells offer great promise for heavy-duty trucks in applications requiring a higher density of energy, fast refueling, and additional range," said Persio Lisboa, Navistar president and CEO. "We are excited to provide customers with added flexibility through a new hydrogen truck ecosystem that combines our vehicles with the hydrogen fuel cell technology of General Motors and the modular, mobile, and scalable hydrogen production and fueling capabilities of OneH2. And we are very pleased that our valued customer J.B. Hunt has committed to utilize the solution on dedicated routes and to share key learnings."
Navistar plans to make its first production model International RH Series fuel cell electric vehicle (FCEV) commercially available in model year 2024. Test vehicles are expected to begin the pilot phase under the new, complete solution at the end of 2022. The integrated solution will be competitive with other powertrain offerings with a target range of 500+ miles and a hydrogen fueling time of less than 15 minutes

The International RH Series FCEV will get its energy from two GM Hydrotec fuel cell power cubes. Each Hydrotec power cube contains 300-plus hydrogen fuel cells along with thermal and power management systems. They are compact and easy to package into many different applications, Navistar says.

The combined propulsion system within the International RH Series FCEV will feature better power density for short-range travel, better short-burst kW output, and a per-mile cost expected to be comparable to diesel in certain market segments.

"GM's vision of a world with zero emissions isn't limited to passenger vehicles. We believe in EVs for everyone," said Doug Parks, GM EVP of global product development, purchasing and supply chain. "We're thrilled to work with like-minded companies like Navistar and OneH2 to offer a complete solution for progressive carriers that want to eliminate tailpipe emissions with a power solution that can compete with diesel."

Under its partnership agreement with Navistar, OneH2 will supply its hydrogen fueling solution, which includes hydrogen production, storage, delivery, and safety. In addition, Navistar is taking a minority stake in OneH2. Through its affiliates, OneH2 plans to kick-start substantial hydrogen heavy truck refueling infrastructure by incorporating more than 2,000 International RH Series FCEVs into existing truck fleets in the near term.

"We're excited about the opportunity to partner with Navistar," said Paul Dawson, OneH2 president and CEO. "We believe strongly that hydrogen fuel is the future of zero-emission renewable energy in the heavy truck market, and are pleased that this agreement will provide additional scope for its application. Under this agreement, we will be able to offer fleets a zero-emission truck with total cost of operation lower than diesel in key segments of the industry."

These newly announced collaborations with General Motors and OneH2 represent important milestones in Navistar's phased development of hydrogen fuel cell solutions. These technologies leverage Navistar's battery electric vehicle platforms and provide the customer with a single-source, fully integrated zero-emission solution that includes vehicles, fueling and service.

"J.B. Hunt is committed to delivering more while using less, and this new fully-integrated solution offers a prime opportunity to do that," said John Roberts, J.B. Hunt president and CEO. "As we serve our customers and communities, the combination of hydrogen fuel cell technology and refueling capability will enable us to reduce emissions along with energy consumption, fulfilling our environmental sustainability commitment to our customers and the communities we serve. We are excited for the potential of this innovative business model and look forward to sharing our learnings from this pilot program with Navistar and its involved technical and infrastructure partners."

PVE announces electric crawler cranes

20210128-150939-PRINT-Volker-WesselsPVECrane02.jpg
Dutch construction contractor Volker Wessels has ordered the first three units of battery-electric crawler cranes from PV E Crane. Pictured, left to right, are: Dick van den Laar, Volker Stevin Materieel at Volker Wessels; Joost Bömer, PVE Cranes & Services; Rob van den Boogaard, Volker Stevin Materieel


Dutch crane and heavy equipment specialist PVE Cranes & Services is developing, with partners, a series of fully battery-electric crawler cranes.

While PVE is known for its piling and drilling rigs, it sold the business manufacturing these a few years ago to concentrate on equipment rental. Now PVE’s new company, PV E Crane, will use the production facility in the Netherlands to manufacture the electric crawler cranes, in compliance with the Electromagnetic Compatibility (EMC) Directive, CE, TüV and other applicable regulations and standards.

The PV E Crane model EC 160 is a 160 tonne capacity lattice boom battery-electric crawler crane
PV E Crane’s new EC series is announced in conjunction with its first customer, Volker Wessels. The major Dutch construction contractor ordered three units to add to its own equipment fleet for use on construction projects in the Netherlands.

The EC series will be a line of 100 per cent battery-powered lattice boom and telescopic boom crawler cranes. Lattice boom models announced initially are the EC 80, EC 90, EC 100, EC 135 and EC 160, in capacities as per the model numbers. Crawler telescopic boom models announced initially are ECT 65, ECT 80 and ECT 120, also where the capacities correspond to the model numbers.

The first model produced will be the 160 tonne capacity EC 160 with 43 metre lattice boom and 42 metre luffing jib. At the time of writing in early January 2021 the designs were ready and components and parts were on order. Testing of the first unit will begin in July or August and the first machine will be ready for delivery in the 4th quarter of 2021, Joost Bömer, PVE Cranes & Services chief executive officer, told International Cranes and Specialized Transport.

Component and fabrication suppliers include Avezaat, Bosch Rexroth, Fuwa, Hirschman and UMS. Special engineering is done in the Netherlands by Eager One (formely Euro Rigging). The 650 Volt water cooled electrical system with DC to DC converter is being developed in conjunction with an automotive industry electric vehicle specialist in the Netherlands.

As fully 100 % battery-powered cranes they will emit no oxides of nitrogen, no carbon dioxide and little sound at the point of use – zero emission, Bömer said. PVE claims sufficient battery capacity for a full eight hour shift of operation before recharging is necessary. Maintenance requirements are greatly reduced when compared with diesel machines.

In terms of initial purchase price the 160 tonne battery-electric model will carry a premium of 10 to 15 % over a diesel equivalent. The return on investment will be made quickly, however, and then be much greater in the machine’s overall life, Bömer explained.

The EC 160 will have a 200 kW electric motor in place of an engine. This will be used to drive the hydraulic pumps as per a conventional hydraulic crawler crane. Replacing the diesel tank will be a 260 kWh lithium-iron-phosphate (LiFePO4) battery pack. These batteries are the latest development in traction cell technology and have some major advantages, the company said.

“They are super safe, chemically stable and inert. They have a long life and you can recharge them from any level of charge without shortening their life – they are not subject to ‘memory’ issues, said Joost Bömer. PV E Crane will give a 3,000 load cycle, or 5 year, warranty on the batteries. “The batteries are very efficient. Charging at 45 kWh per hour from a typical 63 Amp site supply means less than six hours to fully recharge the 260 kWh battery from empty to full,” Bömer continued.

In addition, LiFePO4 batteries are 100 % maintenance free and do not need, for example, any topping up with demineralised water like conventional lead acid batteries do. They are 100 % recyclable as they do not contain any toxic acids or heavy metals, Bömer said.

Netherlands-headquartered PVE Cranes & Services is known as a crawler crane rental house and supplier of heavy duty piling and drilling equipment. It has more than 100 crawler cranes in its fleet and operations around the world. This latest announcement comes just over a month after Liebherr launched its Unplugged electric crawler cranes for construction.

The World’s First Battery-Powered Crawler Crane Has Arrived From Liebherr

eqw.liebherr-lr-1250-unplugged_1.png
The Liebherr LR 1250.1 unplugged has a maximum lifting capacity of 250 metric tons.

While many manufacturers are introducing electric compact equipment, German manufacturer Liebherr is debuting its second electric-drive large machine: crawler cranes.

The company says its LR 1200.1 unplugged and LR 1250.1 unplugged models are the world’s first battery-powered crawler cranes. The electric-driven engines have a system performance of 255 kilowatts (341 horsepower). The LR 1200.1 unplugged has a maximum lifting capacity of 200 metric tons and the LR 1250.1 lifts 250 metric tons.

The cranes follow the company’s LB 16 electric drill rig, introduced at the Bauma trade show in 2019.

As with the 265-kilowatt (355 horsepower) electric-motor LB 16, Liebherr says a design imperative with the electric-drive cranes was that there would be no performance depreciation between them and their diesel cousins.

eqw.Screen-Shot-2020-12-16-at-7.40.53-AM.png
The charging port on the Liebherr LR 1200.1 unplugged and LR 1250.1 unplugged crawler cranes is located in the undercarriage area.
Another key: that each machine is capable of putting in a full day’s work on one charge. On the drill, that meant a 10-hour shift; the cranes are designed to accomplish four hours of lifting operation on one charge.


The cranes can be recharged on a conventional jobsite electric supply in 4.5 hours; a 2.5-hour rapid charging option is also available. After charging, the cranes can be operated without a cable. The charging port is located in the undercarriage area, giving it ground-level access.

Liebherr says the crane batteries supply sufficient energy for the erection of the main boom with luffing jib and for traveling over a distance of about 650 meters (2,132 feet).

Liebherr also notes the crane’s “very low noise level” although no decibel levels were provided.

On the drill, Liebherr compared the unit’s battery capacity to that of seven current Tesla models, which have a driving range of roughly 1,800 miles.

The strategy used with the LB 16 drill “is a complete success” and so now is being extended to the crawler cranes, says Gerhard Frainer, managing director for sales at Liebherr-Werk Nenzing GmbH.

“Strict requirements regarding environmental sustainability in tenders for construction projects increase the demand for advanced technologies,” Frainer says. “For us, it was clear that we extend and successfully establish the design in further product groups.”
