CB is launching its fi rst 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 ful- ly electric version of the popular Loadall.
Future needs Designed to deliver the same performance as the conven- tional 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 cus- tomers in a variety of industry sectors, providing zero-emissions operation for working inside live- stock buildings, crop grading and storage sheds, glasshouses and polytunnels, while also com- plementing the growing use of battery-powered professional groundscare machinery used by golf courses and specialist con- tractors.
In addition, the new telehan- dler can draw on low-cost renew- able energy on farms and other rural enterprises that generate their own ‘green’ electricity, of-

Loadall goes all electric as zero emissions take centre stage
fering a true zero-emissions load handling solution for use in agri- culture and commercial horticul- ture, as well as for groundscare, landscaping, construction and in- dustrial applications.
Pioneering JCB Chief Innovation Offi cer Tim Burnhope said: “JCB has taken a pioneering lead in the move to electric propulsion in construc- tion, agricultural and industrial machinery, having successfully introduced the 19C-1E mini ex- cavator 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 electrifi cation further into general construc- tion, industrial and agricultur- al markets, offering a zero emis- sions load handling solution with no compromise in performance or productivity. We are very ex-

We are very excited about the prospects for this machine

The 525-60E uses two proven
electric motors, one for the drive- line and the second to power the hydraulic system. The 17kW trac- tion motor drives through a per- manent four-wheel drive dropbox to proven JCB drive/steer axles. A 22kW hydraulic system mo- tor powers a fi xed displacement gear pump, delivering a maxi- mum of 80 litres/min of fl ow pro- portional to joystick position, with boom lift/lower controlled by an electro-hydraulic valve block, with hydraulic regeneration on boom lower and retract.
Efficiency
The electric motors are 85% effi - cient, which compares well with
the 45% effi ciency of a diesel en- gine. Extensive analysis of cus- tomer duty cycles, through JCB’s LiveLink telematics system and on-site studies, tests and evalua- tion, 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 mo- tor utilises regenerative brak- ing, instead of a tradition- al braking system, topping up the battery in the process, and automatically turning off when the battery is fully charged. The hydraulic system regenerates oil fl ow fl ow whilst lowering the boom, reducing the power re- quirement and extending oper- ating hours.
The fully electric machine is expected to sell at a 70% premium to the £60,000 diesel version.
