JLG innovates with hybrid boom launch
By Euan Youdale27 February 2014
JLG Industries has launched, what it describes, as the world’s first true four-wheel electric-drive hybrid boom. It will be on show at ConExpo in Las Vegas, starting on Tuesday 4 March.
The JLG H340AJ is designed to perform on par with its diesel powered alternative, explained Jeff Ford, JLG Industries global product director, aerial work platforms.
“It has four independent electric-drive motors that provide unprecedented rough terrain performance and relies on an environmentally friendly, Tier 4 diesel-powered generator for recharging.”
Electric power is stored in eight 6V batteries, each requiring less recharging time than lead acid batteries. Mr Ford added that compared to an all-diesel machine, the H340AJ provides substantial fuel savings, is quieter - at less than 69 decibels - and produces fewer carbon emissions.
Whether in standard two-wheel drive or optional four-wheel drive, the hybrid is designed to operate in harsh environments, including muddy and rugged terrain. A steel hood increases the boom’s durability.
Thanks to brushless AC motors, the variable-speed motors operate smoothly and quietly, and feature proportional control. Direct AC electric drive reduces the number of hydraulic hoses and fittings as well as the potential for leaks, added the manufacturer.
Battery-only operation allows the H340AJ to be used indoors or outdoors and in other emissions-free areas.
The hybrid boom features a platform height of nearly 34 ft, a 17-ft up-and-over reach, and a platform capacity of 500 pounds.
