The company says this development will increase its appeal in countries with a colder, wetter climate. JCB says the machine will use the same cab as JCB’s conventional 1-2-ton models and will be equipped with an electric heater to provide instant heat to demist windows and warm the cab working environment for the operator.
With a large, glazed area, the company says the ROPS/FOPS cab is equipped with easy to replace laminated flat glass. The company says it has a 70/30 front windshield split, with clear jointing, for an unobstructed view of the digging area.
JCB says the cab offers a clear view all around the machine and uses the same LED working lights and wipers as the diesel models, making it easier to work in poor visibility or during hours of darkness when required.
When operating the machine with the heater on, JCB says there is zero impact to the machine’s digging or tracking performance, and the battery capacity allows a full day’s shift to be worked.
The company says the addition of a cab option will increase the appeal of the 19C-1E in regions with challenging weather conditions, where a canopy is not suitable. JCB says the E-Tech cab provides a dry, comfortable operating environment throughout the working day, with a locking door adding to the security of the machine for contractors and rental companies.
Off-board rapid universal charger
JCB says it has also developed a rapid universal charger, compatible with current and future E-Tech electric models.

Working with machine electrical systems from 48V to 96V and above, the company says the universal charger offers customers a future-proofed off-board rapid-charging solution, to allow extended working capability with battery electric construction and industrial machinery.
JCB says all E-Tech equipment is supplied from the factory with a standard built-in charger and rapid charger preparation, allowing customers to simply and quickly cap off the charge and return to work. The company says the charger unit, which is available through JCB dealers and JCB parts, can be easily installed at any site offering 480V three-phase electrical supply.
By offering a universal charger, rather than chargers dedicated to each product line, JCB says it is delivering a single rapid-charge solution, which can be used across a fleet of machines on site or in the yard. The company says the unit can recharge the 19C-1E electric mini excavator from zero charge to full in just 2.5 hours, allowing for quick turnaround and boosting productivity potential.
The company says the universal charger requires a standard 480V three-phase electrical supply and comes with both four and five-pin connectors, to suit site power provision across Europe. It will also be offered in the North American market and across the world.
All-electric Loadall telescopic telehandler
JCB says it also expanded its E-Tech range of zero-emissions machines with the launch of its electric Loadall telescopic handler model.
More than 43 years after the company pioneered the concept of telescopic handlers, JCB says it is introducing the 505-20E, a fully electric version of the popular Loadall. Designed to deliver the same performance as the conventional diesel-powered machine, the company says the 505-20E offers a zero-emissions material handling solution to construction, industrial and agricultural customers.

We are very excited about the prospects for this machine.”å
Key features of the new Loadall include:
- Dual electric motors
- Brake regeneration
- Regenerative hydraulics
- Full shift operation capability
- Range of charging options, including on-board and off-board rapid charging
The company says the 505-20E uses two electric motors, one for the driveline and the second to power the hydraulic system. JCB says the 23 hp traction motor drives through a permanent four-wheel drive dropbox, to JCB drive/steer axles.
The company says the 30hp hydraulic system motor powers a fixed displacement gear pump, delivering a maximum of 21 gal/min (80 l/min) of flow.
The company says the flow is proportional to joystick position and the lift end is controlled by an electro-hydraulic valve block, with hydraulic regeneration on boom function.
JCB says extensive analysis of customer duty cycles, through JCB’s LiveLink telematics system and on-site studies, tests and evaluation, has allowed JCB engineers to optimize the machine’s battery life to meet customer requirements. The company says the 96V Lithium-ion battery is capable of providing full-shift operation.
JCB says the traction drive motor utilizes regenerative braking, instead of a traditional braking system, topping up the battery in the process. The company says the hydraulic system also regenerates flow while lowering the boom, reducing the power requirement and extending operating hours.
JCB says the brake regeneration function automatically turns off when the battery is fully charged, and the machine has a 240V, 16A on-board charger capable of recharging the battery in eight to 10 hours. The company says an optional JCB universal charger can be used for a rapid top-up during breaks, in as little as 60 minutes.
The company says the 505-20E 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 buildings, in underground construction and maintenance work, shipping ports, on environmentally friendly sites, around hazardous materials and in urban areas with stringent emissions regulations.
JCB says a secondary benefit of electric operation is a significant reduction in noise levels, making the Loadall suitable for extended operation in noise restricted areas such as schools, inner city work and hospitals. The company says the 505-20E delivers an in-cab noise level of 66.7dB, while the external level is 92.2dB. The company says a white noise reversing alarm is available as an option, to warn site workers of machine movement.
JCB says the full-size ROPS/FOPS cab is ergonomically designed for fatigue-free operation, with easily located controls, and the machine will be offered as a cab or canopy.
The company says the maximum lift capacity is unchanged from the diesel model as the 505-20E has the same 5500 lbs capability. External dimensions also remain the same with 12 ft 1 in outside turn radius and overall height of 6 ft 2 in.
The company says the machine has been designed to deliver similar cycle times as the diesel telescopic, with no loss of performance, and it can be used with forks, a range of buckets and many other JCB Loadall attachments.
