JCB has launched its first-ever electric Loadall model 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 are off the 525-60E.
JCB has launched its first ever-electric Loadall model as the expansion of its E-TECH range of zero-emissions machines gathers pace.
It has designed the machine to deliver the same performance as the conventional diesel-powered machine. 525-60E offers a zero-emissions load handling solution to construction, industrial and agricultural customers.
JCB Chief Innovation Officer Tim Burnhope: “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.”
Key features of the new Loadall include:
- Dual electric motors for drive and lift deliver increased efficiency.
- Brake regeneration boosts battery charge.
- Regenerative hydraulics increase efficiency
- Full shift operation capability
- Range of charging options, including on-board and rapid charging
Firstly, 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.
The 22kW hydraulic system motor powers a fixed displacement gear pump, delivering a maximum of 80 litres/min of flow.
An electro-hydraulic valve block controls the lift end, with hydraulic regeneration on boom lower and retract. Furthermore, 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 providing full-shift operation.
The traction drive motor utilises regenerative braking, instead of a traditional braking system, topping up the battery in the process.
The hydraulic system also regenerates flow whilst lowering the boom, reducing the power requirement, and extending operating hours. The brake regen function automatically turns off when the battery is fully charged.
The machine has the same onboard charger as other JCB E-TECH products, capable of recharging the battery in 8 hours using a standard 240V, 16A electrical supply.
Furthermore, an optional JCB Universal Charger can be used for a rapid top-up during breaks, in as little as 35 minutes.
Current and future customer demands
JCB has designed the 525-60E to meet current and future needs of customers in a variety of industry sectors.
A secondary benefit of electric operation is a significant reduction in noise levels, making the Loadall suitable for extended operation in sensitive urban job sites.
The 525-60E delivers an in-cab noise level of just 66.7dB, while the external level is 92.2dB. A white noise reversing alarm is available as an option, to warn site workers of machine movement.
JCB has designed the well laid-out full-size ROPS/FOPS for fatigue-free operation. The fully glazed cab has a 2.2kW heater, heated front, rear and side screens, and a heated suspension sea.
Also, 525-60E uses JCB’s well-proven and patented Load Control System, ensuring optimum safe load handling.
External dimensions are unchanged from the diesel model, and the 525-60E offers the same 3.7m outside turn radius. Maximum lift capacity is 2,500kg, with a 2,000kg maximum load at the full six-metre lift height.
The machine has been designed to deliver similar cycle times as the diesel telescopic, with no loss of performance.
In conclusion, operators can use it with forks, a range of buckets and many other JCB Loadall attachments.
