Following on from the launch of its electric-powered 19C-1E mini-digger and 30-19E Teletruk, JCB continues to expand its line-up of ‘E-Tech’ machines with the reveal of an electric-powered Loadall telehandler model.
Based on the diesel-powered 525-60, the new 525-60E is designed to deliver the same performance but with zero emissions. As well as agriculture, the machine is also aimed at horticulture, grounds care, construction, industrial application and equine markets.
External dimensions are unchanged from the diesel model, with the 525-60E offering the same 3.7m outside turning radius, maximum lift capacity of 2,500kg and a 2,000kg maximum lift to its six metre lift height.
The 525-60E uses two electric motors; a 17kW driveline motor drives through a permanent four-wheel drive dropbox to the machine’s axles, while a 22kW hydraulic system motor powers a fixed displacement gear pump, delivering a maximum 80 litres/min of flow.
Oil flow is proportional to joystick position, with the hydraulic motor reacting to the demands in oil flow. Unlike a conventional telehandler, this means you do not need any ‘revs’ to make the hydraulic system work.
Similarly, because the hydrostatic transmission has been ousted in favour of electric drive, forward speed control is also directly proportional to pedal input. This adds up to total independent control over forward speed and hydraulics.
Electric motors are said to be 85 per cent efficient, compared with the 45 per cent efficiency of a diesel engine.
Power comes from a 96V Lithium-ion battery. JCB has not yet put a figure on how long the run time is between charging, but says the machine is capable of a ‘full shift’ and the batteries will work effectively between -20 and 60 degrees celcius.
Able to top the battery up on the go, the drive motor uses regenerative braking instead of a traditional braking system. The brake re-gen function automatically turns off when the battery is fully charged.
The hydraulic system also saves energy which regenerates flow while lowering the boom, reducing the power requirement.
As used on its other E-Tech products, the machine has the same on-board charger, capable of recharging the battery in eight hours using a standard 240V, 16A electrical supply. An optional JCB Universal Charger can be used for a rapid top-up during breaks, in as little as 35 minutes, it claims.
The manufacturer says the machine particularly suits those businesses which are producing their own renewable electric.
Due to its near silent running, in-cab noise levels are 66.7dB, while external levels are 92.2dB. A white noise reversing alarm is available as an option, to warn workers of machine movement. The cab features a 2.2kW heater, heated front, rear and side screens and a heated suspension seat.
