April 7, 2025; Linamar Corporation’s (TSX:LNR) Skyjack division has announced the launch of a new range of hybrid electric rough terrain articulated booms in the SJ45 AJHE+ and SJ60 AJHE+. The new machines offer three modes of operation with electric, automatic and manual.

Available with 51ft (15.7m) and 66ft (20.1m) working heights and suitable for indoor and outdoor use, the SJ45 AJHE+ and SJ60 AJHE+ models include many of the design features that users come to expect from Skyjack - including Skyjack’s unique EASYDRIVE™. Following the earlier all-electric boom launch in June of 2023, the hybrid range also offers high performance AC electric traction, while pump/generator motors deliver high torque power and consistent multi-function capability. 

“Our new range of hybrid electric rough terrain articulated booms have been developed to provide a clean, quiet and sustainable rental solution featuring low emissions, lower operating costs and increased utilization,” shared Skyjack President Charlie Patterson. “As always, our new range remains simple and reliable, providing an environmentally friendly and sustainable choice for rental.” 

A 24.8 hp diesel engine provides sustainable, on-board charging.  HVO compatibility provides a fossil-free alternative fuel with over 90% reduction in greenhouse gas emissions compared to regular diesel. The engine/generator is configured in series with an electric drive motor, providing mechanical drive power.
The hybrid-electric models have two methods of charging. Firstly, users can plug the machine into an external power source, giving the ability to achieve 100% charge using the machine’s onboard smart battery charger. In the “electric” setting the machine runs on electric power derived from the AGM battery pack only. A reserve operation feature prevents a full discharge of the batteries to promote optimum battery life.

Secondly, a series of two settings can be used to charge which delivers a bulk charge of up to 85% from the engine on the machine itself. In the “automatic” setting the engine starts when the charge level decreases to 35% and stops running when the charge level reaches 85%. Bulk charging to 85% takes less than 2.5 hours. In the “manual” setting the engine can be started at any time and it will charge and maintain the batteries at 85%. If the engine is started with the charge level at or above 85%, it will run for 3 minutes then stop.

Skyjack’s new booms also have an optional self-generated power to platform feature in the form of a dedicated generator and switch. This allows the engine to run continuously and provide power to the platform. If the batteries are charged to 85% or above, the engine will continue to run without adding additional charge to the batteries until the power to platform switch is manually turned off. 

“The SJ45 AJHE+ and SJ60 AJHE+ have been designed to meet true job site performance expectations, whether it be navigating various rough terrain conditions or lifting the platform,” explained Mark Trowman, Product Development Manager EAME, Skyjack UK. “Increased platform capabilities of up to 454kg (1000lbs) - plus a superior driving experience and consistent, multi-function capability - boost productivity and efficiency.”

All electric, four-wheel, axle-based drive provides improved efficiency and rough terrain performance. The drive system uses a high-performance AC induction traction motor and AC pump generator/motor system to optimise current torque, power and speed. An oscillating steer axle works in conjunction with the drive system to keep all four tires in contact with the ground, even in the roughest of terrain. Improved traction provides a noticeably smoother ride and consistent multi-function capability delivers a superior operator experience.
