Electrical JCB digger wins MacRobert award


Introduced in 2019, the 19C-1E excavator is the world's first volume-produced completely electric digger. To date, the existing fleet has actually reportedly conserved the equivalent of 15,100 kg in CO2 emissions across 5,616 hours of work. It is estimated that if utilized throughout the global construction sector, which contributes 39 percent of all carbon emissions, these cost savings could reach billions of tonnes.

JCB's winning team are Tim Burnhope FREng, Chief Innovation Officer, Bob Womersley, Director of Advanced Engineering, Lee Harper, Chief Engineer-- Electrified Machines, Lee Milward, Design Manager, and Corey Smith, Test and Development Manager.

Prof. Sir Richard Friend FREng FRS, Chair of the Royal Academy of Engineering MacRobert Award judging panel, said: "JCB's electric digger is a huge engineering achievement. The team has established all parts of the electric propulsion system to provide system efficiency that matches real customer requirements.

" This is a huge achievement in itself, but the additional benefits of zero exhaust emissions and much lower noise has lifted the 19C-1E excavator to a new level."

He added that the digger could be a catalyst for change in a market responsible for 10 percent of the UK's carbon emissions.

According to JCB, the 19C-1E shares the same structure, canopy, dig end, hydraulics and controls as the diesel version of the very same device. Its 4 battery-pack can be charged with a 110V yellow industrial socket, with the choice of a 230V commercial 3 pin blue socket. The business include that a quick charge choice has a charging time from empty of 2.5 hours from a 415V supply.

" To win one of the world's most respected engineering prizes is an outstanding endorsement for JCB's electrification team, who have achieved so much in applying a science which was new to our business," stated JCB Chairman Lord Bamford. "JCB's electric mini excavator will contribute to a zero-carbon future and help make the world more sustainable. It's a big honour for our contribution to be recognised in this way."

JCB's electric digger was selected by the MacRobert Award judging panel ahead of the all-electric I-PACE sports utility vehicle from Jaguar Land Rover and ecoSMRT liquid gas reliquification technology from Babcock's LGE business.
