Electrification of construction equipment is nothing new to the industry at this point.
Many heavy machinery manufacturers have released prototype, production, or concept versions of numerous electric, hybrid-electric compact machines such as mini excavators, compact wheel loaders, skid steers, and compact track loaders.
Komatsu’s entry into the electric realm was unveiled more completely at ConExpo-Con/Agg 2023. Prototypes and concept electric machines including the PC30E mini excavator, the PC01E micro excavator, and a fully electric prototype of the company's WA70 wheel loader were displayed.
First displayed at Bauma 2022, the company’s showcase piece is the PC210E mid-sized electric excavator. A pilot program with contractors is expected to be initiated in the latter half of 2023 for the 20-metric-ton electric excavator.
"This excavator stands out by integrating a Proterra-powered lithium-ion battery that enables clean, eco-friendly operation of up to eight hours," said Andrew Earing, director of product and technical services at Komatsu. “Being able to harness this emission-free electric power will enable your construction business to work comfortably in various work environments without worrying about exhaust or noise emissions.”
Only a handful of other OEMs have announced development of battery-powered machines of that size due to the challenges in charging time, performance, overall runtime, and price.
Like its smaller electric machines in development, Komatsu said, the PC210E is identical to its diesel counterpart, the PC210LC-11, in performance and general specifications.
