Test Drive: How Kenworth’s fuel cell T680 delivers a quick, quiet ride


California Governor Jerry Brown wants 5 million zero-emission vehicles on state roads by 2030. By the end of next month, one of them will be shuffling around the ports of SoCal.

Kenworth’s hydrogen fuel cell Zero Emissions Cargo Transit (ZECT) T680 tractor, the fruit of a $7 million project between the Kirkland, Washington, truck-maker, the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy and Southern California’s South Coast Air Quality Management District, has been undergoing testing in the Seattle-area since December and will head off to Total Transportation Services and the ports of Los Angeles and Long Beach in about six weeks.

This week, I was able to participate in the testing of the no-NOx daycab on the highways around Paccar’s Technical Center in Mt. Vernon, Washington.

With a range of 150 miles (upwards of 30 miles all-electric range) and a top speed of 65 mph, the tractor uses lithium-ion batteries to power a dual-rotor electric motor that drives the rear tandem axle through a four-speed automated transmission.

Loaded to just south of 79,000 pounds, the truck builds speed quickly and silently with the equivalent of about 565 horsepower and just more than 1,850 lb.ft. of torque. Kenworth Manager of Research and Development Brian Lindgren notes that while the motors are rated at 420 kW (565 hp) at a constant rate, they will peak higher. However, the company has limited the truck’s output to about 300 kW until the systems are validated.

The torque at launch is noteworthy but as the truck builds speed it begins to feel much more “normal.” But it certainly doesn’t sound normal. Other than the faint whine of the cooling fans, the truck doesn’t make much sound. With enough road noise you’ll forget you’re driving a hydrogen powered truck.

Six onboard tanks – 5 kg each and pressurized to 5,000 PSI – hold the equivalent of about 30 gallons of diesel and can be filled in less than 15 minutes. The Department of Energy estimates lists 39 hydrogen retail stations nationwide. The highest concentration is in California, but there are none in the 2,500 miles between California and South Carolina.

The Ballard Power Systems HC85 fuel cell – mounted where you would expect to find an MX engine – produces an electrical current of about 400 volts DC, which is converted to 650 volts DC and stored in the truck’s batteries, a one-ton bank mounted under the cab. With an expected battery life of six to 10 years, the zero emission T680 is equipped with battery heaters and chillers to limit the effect of weather on range.

The shift to electric mobility generally places an electric motor on each wheel but the T680 maintains a traditional driveline, with a dual rotor AC motor in the frame sending power via a shaft to a standard rear end. Moving motors to the wheels changes the unsprung dynamic characteristics of the axle. By not changing how the wheelends sit on the truck, Kenworth designers were able to spend more time developing the powertrain system.

The Kenworth T680 day cab’s fuel cell combines compressed hydrogen gas and air to produce electricity with only water vapor/steam emitted from a snorkel that exhausts near the roof of the truck. The electricity can power the dual-rotor electric motor to move the truck or recharge the batteries. In the event you end the day with less than a full battery charge, a 13kW onboard charger provides an overnight plug-in option.

The hybrid drive system manages the power from the fuel cell to and from the batteries, as well as the traction motors and other components, like the electrified power steering pump and the brakes’ air compressor.

The truck will make about 3,800 lb.-ft. of torque but that is limited to save wear and tear on a stock rear-end that is designed to handle roughly half that amount.

Shifting is handled through the back half of an Eaton Fuller 18 speed gearbox. It uses the same range and splitter, which provides a low-end ratio of about 4.3 and a direct top end. The lower-end ratio gives the truck excellent startability and enough torque to start up a 20 percent grade while the top-end gives the truck enough power to maintain 30 mph up a 6 percent grade – well above the average drayage speed of less than 20 mph.

Stephan Olsen, Kenworth director of product planning, says batteries themselves weigh-in at 2,000 pounds. The battery management platform, high voltage cable, coolant lines, enclosure and mounting adds about another 1,500 pounds. All that adds up to the ZECT tipping the scales at about 22,000 pounds – or about 3 tons more than a similarly equipped, diesel-powered T680.

“A lot of that comes from the batteries, some of that comes from cooling [system] and some of that comes from the hydrogen tanks,” says Lindgren.

Olsen says Kenworth testing has shown the hydrogen truck “performs equally as well, if not better than, current diesel trucks on the market.” From my brief time behind the wheel, I would agree.

Beyond the fuel cell itself, much of the T680 is stock equipment – including the suspension and Spicer D40-170P (5.38) rear end – and performed like you would expect a T680 to perform.

The ZECT is only expected to log about 50 miles per day, but the SoCal ports and Kenworth’s ZECT will play an important role in validating hydrogren’s role in trucking.

New Epiroc ER 1500 Drum Cutter features dust-suppression system


Epiroc says its new ER 1500 Drum Cutter for excavators is ideal for tunneling, special foundation work, demolition and soil mixing.

It also comes with a dust-suppression system designed to meet OSHA silica dust-reduction regulations that took effect in September. The system uses water jets to spray the working area to prevent dust from entering the air.

The transverse drum cutter is designed for excavators weighing 20 to 40 tons. It produces 160 horsepower and a cutting force of 9,100 to 15,700 pound-feet at 5,000 pounds per square inch.

The cutting head is 35 inches wide and features 44 tungsten carbide-tipped picks. The company says the attachment provides each pick with maximum cutting power at the recommended rotation speed of 75 rpm. Epiroc designed the cutter’s gear housing to be rigid and wear-resistant and added hardened wear sleeves to the pick boxes, the company says.

The cutter can rotate 360 degrees without having to be disconnected from the excavator. A high-torque hydraulic motor drives the large spur gears. It operates quietly with low vibration and can be used in sensitive areas, the company says.

Epiroc is a subsidiary of Atlas Copco and will officially split into its own company, pending Atlas Copco shareholder approval expected in April. Epiroc focuses on mining, infrastructure and natural resources, while Atlas Copco will focus on industrial customers.

New NAPA chairman urges members to focus on safety, quality and following through

The Silver Star Construction crew from Moore, Oklahoma, was following all the safety rules on that spring morning as they paved. Distracted, the driver of a pickup truck bore down on the work zone at 50 miles per hour.

The catastrophic accident that unfolded in the next few moments touched off a crusade for the commercial paving company of Craig W. Parker, the new 2018 chairman of the National Asphalt Pavement Association (NAPA). He’s vice president of Silver Star, an employee-owned company. Now, as he assumes his new post, Parker is taking his safety cause coast-to-coast.

“You can rest assured that NAPA and I are committed to enhancing safety for the industry,” Parker told about 900 people at the association’s 62nd annual meeting in San Diego this week. “This is a major focus for NAPA in 2018.”

Just after taking his oath to the leadership role on Monday, Parker implored members to commit to three goals in the next year: “safety, quality, and following through.” Company leaders can make a difference by setting an example and pushing for change, he assured them. And there’s much at stake.

“Everyone in this room knows that this industry can be dangerous,” Parker says.

“More than two roadway construction or maintenance workers are killed on the job every week. Another 40 workers are injured every day.

“Roadway accidents cost more than $500 million annually, according to data from the U.S. National Institutes of Health. Each death in the construction industry costs approximately $4 million in direct and indirect expenses; each injury resulting in lost work days costs has an average cost about $42,000.”

Those in the road construction and maintenance business see the dangers up close.

“We routinely have people working within inches of vehicles traveling 50, 60, 70 miles per hour. Folks, if you haven’t had the experience of standing on the white or yellow line at the edge of a construction zone with highway traffic zooming by, I encourage you to get out there, with your crew and see what that feels like – in a safe supervised manner,” Parker says.

“Our safety personal set up these works zones according to the MUTDC (Manual on Uniform Traffic Control Devices). And then we put our people – the construction crews, the inspectors, the QC (quality control) people, and the engineers out there with a few bits of plastic between them and several thousand pounds of steel traveling from 20 to 70 miles per hour. That’s the environment we live in.”

Silver Star Construction not only produces and lays asphalt, they have three mass dirt crews, 11 stabilization and grading crews, three asphalt and milling crews, two drainage and small bridge crews and four concrete crews.

The accident happened as Parker’s workers were paving a two-lane road on April 13, 2017.

“Our crews, the foreman, the superintendent, the safety director, and the traffic control subcontractor did everything right, but the accident still happened, Parker recounts.

Flagman acts heroically

This job involved using a flagging operation. In the sequence of the operation, the pilot car had just made the turn, and the flagman, Justin, had one car stopped at the flagging station.

“Now this was not a busy highway. Maybe a car every two to three minutes. With the first car in sequence stopped, our flagmen could see a pickup approaching, but it didn’t seem to be slowing down. Watching that pickup, Justin was sure it was not going to stop,” Parker recounts.

“He got the attention of the woman driving the car which was already stopped – who also had a 4-year-old child in the back seat ­– and started yelling at her to move off the road.”

The woman – who was the wife of a DOT workers – pulled to the side, and Justin moved quickly to get off the road himself.

“The pickup driver, finally, looked up and saw the car, but he didn’t see Justin. The pickup missed the car but struck Justin, knocking him approximately 80 feet.

“When the first responders got to the scene, they didn’t give Justin much of a chance of surviving.”

Justin spent about 60 days in a coma. This past December, he was able to join coworkers at the company’s annual Christmas party.

“Justin still has a long road to recovery in front of him — it could be as long as two years — and we don’t know if he’ll ever be able to come back to work, but we continue to pray for him daily. Justin is true a miracle,” Parker says. “The good Lord has other plans for Justin, or else he wouldn’t still be with us today.

“I share Justin’s story because it made us take a new look at what we require of our people when it comes to safety and what engineering devices we have available to protect our people.”

Technology and devices to help keep road workers safe

Parker is sure a technology is out there that could possibly have keep this accident from happening.

“Unfortunately, it sometimes takes a major incident for contractors like us to do the research and see what is happening in other areas of the country, to find ideas and solutions that we just haven’t been exposed to yet,” he says.

In their research, Silver Star learned of a few things that are helping to make work zones safer in other areas of the country: automated flagging stations, portable rumble strips, and remote photo enforcement of speeders in active work zones.

“Last April, when Justin’s accident happened, we did not have the DOT specifications available for any of these new devices for highway work in Oklahoma. I’m happy to tell you that our DOT is now actively working on getting these standards reviewed for implementation,” Parker says.

“Our AGC in Oklahoma is now pushing for legislation in Oklahoma to allow photo enforcement in active construction zones,” he says of the state chapter of Associated General Contractors. “Only a few states currently allow photo enforcement.”

As the research introduced them to automated flagging stations, Silver Star found an obscure construction standard for portable rumble strips. “It has only been used occasionally for ODOT maintenance crews, and not for new contract construction work. We are looking to deploy a new standard soon,” he says.

Parker advised members that during their annual meeting, they would more about NAPA Care, which is Emergency Benevolent Fund established by the asphalt pavement industry to support the family of a NAPA member employee who suffers a fatal accident while working in the line of duty.

They would also hear about their work zone training partnership with ARTBA, NAPA’s safety pavilion at World of Asphalt, and a new public awareness campaign developed by the Go to Market Task Group, including a powerful road safety video that would debut before them on Wednesday, February 14, 2018.

Committing to quality and following through

As NAPA’s 2018 chairman, Parker also told members that he wanted all of them to commit to quality. “You will hear a lot more from me over the next few months on ideas and ways we can help our crews step up their game and commit to delivering a quality product every day,” he says.

A third area they must all commit to is “follow through,” Parker says.

“As the leader of a company, all of your employees look to you for guidance. They also emulate your actions. If you are 100 percent committed to excellence, your employees will see that in the decisions and directions you give daily. They will emulate your actions, good or bad.”

Parker pledged that he will spend the next year working with NAPA on these focus areas. And he urged members to make the same commitment for the benefit of their companies and the industry as a whole.
