JCB is launching its first ever electric Loadall as the expansion of its E-Tech range of zero-emissions machines gathers pace.
More than 43 years after the company pioneered the concept of telescopic handlers, the wraps have come off the 525-60E, a fully electric version of the popular Loadall.
Designed to deliver the same performance as the conventional diesel-powered machine – 2,500kg maximum lift and 2,000kg to the 6.0m full lift height – the Loadall 525-60E
has been designed to meet the current and future needs of customers in a variety of industry sectors, providing zero-emissions operation for working inside livestock buildings, crop grading and storage sheds, glasshouses and polytunnels, while also complementing the growing use of battery-powered professional groundscare machinery used by golf courses and specialist contractors.
In addition, the new telehandler can draw on low-cost renewable energy on farms and other rural enterprises that generate their own ‘green’ electricity, offering a true zero-emissions load handling solution for use in agriculture and commercial horticulture, as well as for groundscare, landscaping, construction and industrial applications.
JCB Chief Innovation Officer Tim Burnhope said: “JCB has taken a pioneering lead in the move to electric propulsion in construction, agricultural and industrial machinery, having successfully introduced the 19C-1E mini excavator and the 30-19E Teletruk to the market.
“As world market leader for telescopic handlers, the launch of the JCB 525-60E Loadall takes equipment electrification further into general construction, industrial and agricultural markets, offering a zero emissions load handling solution with no compromise in performance or productivity. We are very excited about the prospects for this machine.”
The 525-60E uses two proven electric motors, one for the driveline and the second to power the hydraulic system. The 17kW traction motor drives through a permanent four-wheel drive dropbox to proven JCB drive/steer axles.
A 22kW hydraulic system motor powers a fixed displacement gear pump, delivering a maximum of 80 litres/min of flow proportional to joystick position, with boom lift/lower controlled by an electro-hydraulic valve block, with hydraulic regeneration on boom lower and retract.
The electric motors are 85% efficient, which compares well with the 45% efficiency of a diesel engine. Extensive analysis of customer duty cycles, through JCB’s LiveLink telematics system and on-site studies, tests and evaluation, has allowed JCB engineers to optimise the machine’s battery to meet customer requirements. The 96V Lithium-ion battery is capable of powering the machine through a full working shift.
The traction drive motor utilises regenerative braking, instead of a traditional braking system, topping up the battery in the process, and automatically turning off when the battery is fully charged. The hydraulic system regenerates oil flow flow whilst lowering the boom, reducing the power requirement and extending operating hours.
