As part of its 100th anniversary celebrations, Komatsu has built a concept mini excavator that is fully electric, remote controlled and powered by a lithium-ion battery
Designed to lay the foundations for commercialisation of fully electric construction equipment of the future, the concept machine 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 use no hydraulics.
Thanks to full-electric power, it is an eco-friendly machine, as it generates no exhaust gas, noise or heat.
In addition to improved energy efficiency, it also features maintenance-free operation thanks to no use of hydraulic equipment.
A vehicle controller and operational device are connected via wireless LAN, enabling remote control operations under any work environment.
Thanks to electrification and remote control, the machine is designed to be stress-free for the operator, as it provides for easy work in confined, dangerous sites, such as for indoor demolition and rescue work from disasters.
Sean Taylor, MD and CEO of Komatsu Australia said, “Climate change and moving towards a global zero-emissions economy is obviously the big challenge for our generation.
“Komatsu has a long and rich history of driving sustainable innovation, with industry breakthroughs such as the first hybrid excavator which reduced fuel consumption by over 40% and the deployment of low emission engines that reduce particulate matter by up to 80% – this concept machine is an exciting extension of this journey.”
