Komatsu Ltd. announced a fully electric (non- hydraulic drive) and exclusively remote-controlled mini excavator powered by lithium-ion battery, as its next-generation concept machine for the future.
Designed to lay the foundations for commercialization of fully electric construction equipment of the future, this concept machine for a fully electric 3-ton class (bucket capacity: 0.09m3 ) mini excavator is based on Komatsu’s accumulated technological expertise in electric forklifts and mini excavators, and incorporates new technologies, such as lithium-ion batteries and electric cylinders which utilize no hydraulics. Thanks to full-electric power, it generates no exhaust gas, noise or heat, and offers stress-free operation under any work environment. In addition to improved energy efficiency, it also features maintenance-free operation thanks to no use of hydraulic equipment.
As this concept machine requires no operator on board the machine, Komatsu has achieved totally new concepts related to vehicle designs and performance. A vehicle controller and operational device are connected via wireless LAN, resulting in no need to install facilities or create an environment, which are required in the conventional remote- control system, and enabling remote control operations under any work environment. With respect to the operational devices of the vehicle, the operator can select the one which he/she likes. In 2020, Komatsu launched the PC30E-5 mini excavators in Japan and plans to introduce mini excavators after equipping them with the lithium-ion battery system used in the concept machine for Europe in FY2022.
