Gradall intros Discovery Series excavators designed for emergency cleanup
Gradall says it has come up with a low-cost solution for local and state governments facing emergency cleanup, such as occurred with last year’s string of devastating hurricanes.
The company’s Discovery Series excavators were used during storm recovery on the Gulf Coast and in the Bahamas and Caribbean, a news release says. They can travel up to 55 mph on the road and can reduce the need for additional equipment.
Gradall collaborated with Freightliner engineers to integrate an M2 undercarriage with automatic transmission on the new excavators. They also feature a Cummins 6.7-liter engine with 220 gross horsepower and 520 foot-pounds of torque.

Kenworth debuts a fuel cell-powered T680
Earlier this month, Kenworth made headlines by exhibiting for the first time at the Consumer Electronics Show in Las Vegas and bringing along its zero-emission, hydrogen fuel cell T680.
The high tech day cab, which was part of the PACCAR Innovations booth, gave thousands of visitors a chance to not only see the latest in hydrogen fuel cell tech, but also to learn more about Kenworth’s trial runs in the Seattle area and its plans for real-world testing with Total Transportation Services at the ports of Los Angeles and Long Beach.
The Kenworth T680 day cab’s fuel cell combines compressed hydrogen gas and air to produce electricity with only water vapor emitted at the tailpipe. This electricity can power the dual-rotor electric motor to move the truck up to its top speed of 65 mph, or it can recharge the 100 kHw lithium-ion battery pack for later use.

Liebherr debuts 50 M5 XXT concrete pump truck, a rugged, electronically simplified machine designed to last decades
At the World of Concrete Tuesday Liebherr showed for the first time its new 50-meter truck-mounted concrete pump, the 50 M5 XXT. The pump truck’s five section boom reaches to 161 feet vertically and 146 feet horizontally.
For moving the material, the M5 XXT offers four pump unit options with outputs from 138 to 167 square meters per hour. The four pivoting outriggers are secured directly to the distributor boom pedal which directs the weight from the boom directly into the outriggers with no flexing of the body of the truck. Liebherr kept the weight down and increased stability with a newly designed boom pedestal. The slewing ring and drive are proprietary Liebherr components.
The front and rear outriggers on the M5 XXT pivot on the same point. “This gives you a ton of flexibility as you set up,” says Liebherr’s Clinton Nichols. “Setting up on tight jobsites is very easy to do. You gain more than 180 degrees working range on the boom,” he says.
