Komatsu to exhibit 20-ton-class Proterra-Powered electrical hydraulic excavator at bauma 2022


Komatsu will exhibit a 20-ton-class electrical hydraulic excavator outfitted with a lithium-ion battery system for the primary time at bauma2022. The machine is powered by a 451 kWh lithium-ion battery system from US-based Proterra. Since January 2021, the 2 corporations have been collectively creating electrical medium-sized hydraulic excavators, and have been conducting PoC (Proof of Idea) exams on advance analysis machines at clients’ development websites.

The machine is scheduled to be launched to the Japanese and European markets in FY2023.

Hydraulic excavators are probably the most versatile sort of development tools, and the mid-size class, particularly, is utilized in a variety of jobsites and purposes, primarily in earth excavation and loading operations, requiring energy and sturdiness to face up to heavy-load work.

This mannequin optimizes the complete physique management system by capitalizing on Komatsu’s proprietary coordinating expertise. It particularly integrates Proterra’s lithium-ion battery expertise which has a confirmed observe file to be used in heavy-duty and business autos deployed in numerous fields world wide, with Komatsu’s elements, such because the hydraulic pump, controller, and electrical motor for work tools operation.

As well as, Komatsu has developed a sturdy cage construction to offer extra safety onboard the car for its battery packs. In consequence, Komatsu has achieved digging efficiency and sturdiness equal to these of engine-driven hydraulic excavators. The excessive power onboard the excavator’s Proterra Powered battery system permits operation for as much as 8 hours when absolutely charged.

The electrical energy makes it attainable to work comfortably in numerous work environments with out worrying about noise and exhaust emissions, and is anticipated for use for work in city areas and nighttime development work, and many others. The zero engine vibration will even assist cut back operator fatigue.
