New electric bucket truck from Terex Utilities

Terex Utilities has announced its next generation of a zero-emissions bucket truck for the electric utility industry.

The new range will be displayed on the Mack Trucks booth for the first time at NTEA Work Truck Week, taking place next week in Indianapolis, US.

Terex Utilities has partnered with Mack to produce the lifts that boast enhanced range and more payload than other electric chassis on the market, says Terex. 

Terex installed its Optima HR55 aerial device powered by the HyPowerTM SmartPTO by Viatec on the Mack MD7 Electric chassis. Preliminary testing revealed the unit has up to 1.5-times enhanced range capabilities compared to other Class 6/7 medium duty electric chassis bucket trucks, says the manufacturer, with double the payload capacity on the rear axle.

The Terex aerial device, powered by the SmartPTO, operates independent of the 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.

It follows Terex’s first all-electric bucket truck launched in 2022, with an Optima 55-foot aerial mounted on an International eMV. A limited supply of the new trucks will be available in 2025, with a standard delivery of 12-18 months.

“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, integrating advanced camera systems, AI, and industry-leading technology to provide up to six HD cameras displayed on a spacious 7-inch 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.”
