JCB launches booms and scissor lifts
By Euan Youdale05 May 2023
JCB has introduced full electric and diesel/electric hybrid boom lifts and updated its hydraulically-driven scissor range with six electric drive versions.
The new pair of booms and six scissor models bring the full JCB Access range to three articulted boom lifts and eight electric scissors.
The new A45E and A45EH articulated boom lifts - which are not currently available in North America - offer a maximum platform height of 13.84m with 7.47m horizontal reach, 300kg basket capacity across the entire envelope, along with secondary guarding as standard, slew lock and emergency override, as well as solid rough terrain tyres. They join the existing AJ48D diesel model, first launched in 2021.
While a jib is also standard on both new models, the ‘J’ has been dropped from the nomenclature.
The A45E is powered by eight 6V batteries, creating a 48V, 400AH operating system. The battery packs are located on either side of the lower chassis, maintaining a low centre of gravity for added stability and improved traction. The batteries power AC drive motors via motor controllers and the machine’s hydraulic pump through a hydraulic motor controller.
The A45EH uses a 14.8kW three-cylinder diesel engine and a 7.5kWa generator to power the machine’s eight 6V batteries. The engine is mounted on a swing-out tray, making it easier to service and maintain when required. A 40-litre fuel tank provides enough fuel for a full week of operation, making it ideal for offering low emissions in remote locations. The battery can also be plugged into a mains supply if available.
Rough terrain capabilities
Both of the platforms have four-wheel drive and two-wheel steering as standard. The wheels are driven by four AC motors which recover energy through regenerative braking, to prolong battery performance. With drive provided to each individual wheel, the machine is capable of climbing up to 40% gradients.
An oscillating axle ensures that maximum traction is maintained on rough ground when the boom is stowed. However, the axle is locked, to ensure machine stability, when the machine enters boom raise mode. Foam-filled, non-marking tyres are standard.
The 0.84m x 1.84m platform has three entry points and there are four harness clipping locations, allowing the operator full access around the basket.
A secondary guarding system is provided, automatically halting boom functions when triggered.
The booms are equipped with a Slew Acknowledgment feature, that ensures that the operator must register if the boom is slewed over the side of the chassis before driving when elevated. A tilt sensor prevents machine elevation when the chassis is on unlevel ground, tilting the machine to more than 5°.
JCB’s LiveLink telematics monitoring system provides real-time operating data on performance, service schedules and fault codes. Managers can remotely record engine operation, low fuel warnings, tilt sensor warnings and overload warnings. LiveLink also provide battery voltage, fuel level and platform load percentage data.
These machines are equipped with a 5” colour touch screen display on the platform, providing operators with essential data and controls at their fingertips. This intuitive interface enhances safety and productivity on the job site.
In addition, the machines feature a unique control system that eliminates the need to switch between platform controls and ground controls. Operators can seamlessly operate the machine from either location, eliminating the hassle of switching control modes.
Scissors in focus
The six updated electric drive scissor platforms, starting with three models, the S1932E, S2632E and S3246E, and followed later this year by the S2646E, S4050E and the S4550E, will offer up to 53% more run time than the hydraulic versions.
Platform heights range from 5.71m to 13.8m, with capacities from 230kg to 450kg.
With these new models, the hydraulic drive motors are replaced by electric drive motors. The 53% longer run time on a single battery charge, compared to the hydraulic version reduces overall charging cost and total cost of ownership.
The electric motors also deliver increased torque to the wheels and up to 25% gradeability. With the hydraulic motors replaced, there are up to 50% fewer hydraulic connections on a single-cylinder machine, or 48% on a twin-lift cylinder model, cutting the potential for leaks.
The S1932E model replaces the previous S1930E, adding 50mm to its width, despite a 106kg drop in operating weight. This makes it easier to transport on a trailer or when moving multiple machines. The S1932E offers a platform height of 5.71m and a platform capacity of 230kg. Moving up the range, the S2632E has a platform height of 7.92m with a 250kg capacity and the S3246E offers a 9.7m platform height, but with a higher 320kg weight limit.
Later in the year, the S2646E will provide a 7.9m platform height and a 450kg load capacity, while the S4046E will deliver an 11.9m platform height and 320kg weight limit. Finally, the S4550E has a platform height of up to 13.8m and a 230kg capacity.
The new electric drive scissors benefit from all of the features already seen on JCB’s hydraulic drive models, including safety features such as a full height entry gate, pothole protection and intuitive operator controls.
The machines have swing-out battery and hydraulic trays for easy access, while the proven EPD paint finish, full size pivot bosses and drive motor protection ensure that these durable machines offer long service life with maximum uptime.
