JLG X660SJ

The JLG X660SJ compact crawler telescopic boom is built to reach full height quickly, topping out around 66 ft of platform height with roughly 41 ft of working outreach and a 500 lb unrestricted platform capacity. It runs on a 14.5 hp Kubota diesel engine and can be equipped with an optional lithium-ion electric system for emission-free indoor operation. A 40 percent gradeability rating and its tracked undercarriage let it cross rough or finished surfaces without the ground disturbance wheels leave behind. It suits warehouse maintenance, arena and stadium work, indoor manufacturing plants, and facility upkeep crews needing serious height without floor damage.
