Komatsu's electric, remote-controlled mini-excavator
In a move aimed at those engaged in indoor demolition, confined, challenging site works and disaster rescue, Komatsu has unveiled details of its first fully electric, remote-controlled mini-excavator concept machine. Powered by a 31.5kWh lithium-ion battery, the 3-tonne mini excavator has a 0.09 cubic metre bucket capacity and rear-swing radius of 970mm.
With no operator on board, the excavator is controlled and operated via wireless LAN, which, unlike a conventional remote-control system, enables the machine to operate in any work environment. Thanks to its full-electric power, the eco-friendly machine generates no exhaust gas, noise or heat. In addition to improved energy efficiency, further innovation sees maintenance-free operation as a result of having no oil hydraulic equipment.
Commenting on the Komatsu electric digger, John O’Brien, director at Komatsu distributor in Ireland, McHale Plant Sales, said, “Though the market is somewhat limited compared to conventionally powered equipment, the attractions and benefits of an remote control, emissions-free operation, especially in confined and restricted areas, cannot be underestimated.”
