Terex Utilities and Mack collaborate on electric bucket truck

Terex Utilities has partnered with Mack Trucks to create its next generation of a zero-emissions bucket truck for the electric utility industry.

The battery electric bucket truck boasts an enhanced range and more payload than other electric chassis available today.

Terex installed its Optima HR55 aerial device powered by the HyPowerTM SmartPTO by Viatec on the Mack MD7 Electric chassis to deliver a zero-emissions utility truck that can drive farther and haul more cargo.

Preliminary tests have shown the Terex all-electric bucket truck with the Mack MD7 Electric chassis has up to 1.5 times more range compared to other Class 6/7 medium duty electric chassis bucket trucks, with double the payload capacity on the rear axle. The Terex aerial device, powered by the SmartPTO, operates independent of the Mack MD7 Electric chassis which helps to ease range anxiety and allows utility crews to operate the boom and outriggers for a normal workday without taking away charge from the chassis.

“Our collaboration with Mack Trucks represents continued movement forward in zero-emissions utility vehicles,” said Tyler Schwingler, Terex Utilities Product Marketing Manager.

“By combining our industry-leading Optima HR55 aerial device with Mack’s innovative MDe7 chassis, we’re providing utility companies with a solution that doesn’t compromise on performance or capability while meeting their sustainability goals.”

The all-electric truck is also equipped with the 3rd Eye digital platform, seamlessly integrating advanced camera systems and artificial intelligence to maximize safety and productivity.

With up to six HD cameras displayed on an 18-cm in-cab monitor, the system provides a complete, real-time view of the vehicle’s surroundings, significantly reducing blind spots when reversing, changing lanes or operating in tight or high-traffic areas.

“Best of all, the 3rd Eye System is wirelessly connected to the cloud, continuously capturing and storing critical operational data and video, providing fleet managers real-time visibility into driver performance, chassis and body activity, and equipment status,” said Eric Monsen, Vice President of Sales and Marketing for Environmental Solutions Group. “These comprehensive insights not only improve safety and reduce liability but also create a detailed event record and help identify coachable opportunities to reinforce safe driving behaviors.”

Terex introduced its first all-electric bucket truck in 2022, with an Optima 16.7 metre aerial mounted on an International eMV.

Dozens of Terex all-electric bucket trucks are being used by utility crews throughout North America. The new Mack all-electric unit provides another option for electric utility customers looking for a zero-emissions solution. A limited supply of these trucks will be available in 2025, with a standard delivery of 12 to 18 months.
