On the 12th of March this year, JCB unveiled their first ever attempt at an electric excavator, the JCB 19C-1 E-TEC. It was developed in their top-secret World HQ, in Staffordshire in England and so secret was the design, that March 12th was the first anyone heard of it.
What it offers:
Not only is it the quietest digger (Five times quitter) currently on the JCB market, but it also contributes zero carbon emissions. The lack of emissions means workers can now operate indoors or underground, without having to spend big on exhaust extraction equipment.
The lack of noise, 7dBA lower than other models, means that contractors can now operate from the early hours of the morning, with little complaint from residents. There are minimal battery problems also, as one fully charged battery can carry out a full day’s work.
Other key features of the 19C-1 E-TEC include:
• Three lithium-ion battery packs providing a 312Ah (15kWh) storage capacity
• A standard load-sensing hydraulic system delivering powerful digging performance
• Convenient onboard charger with 230V input for 6-hour recharging capability
• The option for 110V charging when required
• Sophisticated battery management system ensures full-shift availability
• Fast charge option on launch allowing a full charge in 2.5 hours.
Using the latest 48V electrical system, the highly efficient electric motor delivers instant, greater torque than the standard machine’s diesel engine. The motor drives the 19C-1 E-TEC’s proven Bosch Rexroth load-sensing hydraulic system, delivering the same sector-leading digging performance as the standard 1.9-tonne excavator.
The high efficiency of this advanced electric-hydraulic combination means a considerably lower cooling requirement - only a small hydraulic cooler with a small thermostatic electric fan and no engine radiator - contributing to longer battery life and the much lower noise level. The 19C-1 E-TEC is equipped with the same adjustable undercarriage and choice of digging equipment as the diesel model, to provide a maximum digging depth of 2,576mm with the longer 1,100mm dipper arm.
A convenient onboard charger is provided as standard, allowing the machine to be fully recharged in six hours, using a conventional 230V plug. An optional 110V charging system is available for sites without 230V electricity and JCB will offer a fast-charging option once the machine has been launched - a heavy-duty off-board unit, allowing a full charge in 2 1/2 hours.
The self-contained power system means that there is no requirement for an electrical power connection or cable during machine operation. The battery packs allow a full working day in a typical duty cycle or four hours of operation in an extreme duty cycle. The 1.9-tonne machine will be capable of handling a range of powered attachments, making it an ideal base carrier for demolition and refurbishment projects.
Initially, the mini excavator will be available with the ROPS/TOPS and FOGS certified canopy that is offered on all next-generation mini and midi machines.
In an environmentally conscious world, where emissions on petrol and diesel vehicles will soon be penalised, JCB have designed a nifty little machine, which could pave the way for more successful all-electric machinery.
