With 65 feet 7 inches of platform height and 500 pounds of capacity for up to two workers, 39 feet of horizontal reach and indoor/outdoor versatility, the JLG X660SJ model is ideal for a wide range of applications, including arboriculture, painting, general maintenance, electrical, HVAC and window washing on a variety of job sites such as auditoriums, arenas, atriums and outdoor structures.
“The X660SJ is designed with several unique features that are key to efficiently accessing work at height,” says Angela Patterson, JLG boom lift product management lead. “For example, the architecture of this new straight-boom compact crawler boom lift enables operators to reach full height more efficiently, while its crawler-mounted design and 40 percent gradeability mean the X660SJ can climb slopes with ease compared to standard lifts. Its 2-foot 11-inch profile and less than 7,400-pound footprint allow operators to go more places around the job site, such as through gates and standard doorways to work in yards and public buildings.”
Other performance-enhancing features the X660SJ is equipped with include:
- Envelope tracking operation for work alongside buildings, walls and other infrastructure. With a single control function, operators can boom up/down, while also telescoping out/in, so that the platform travels a path perpendicular to the ground
- Multiple position, one-touch self-leveling outriggers provide flexibility to work in tight areas and maximize the working envelope
- "Go Home" and "Back to Work" functions for ease of returning to stowed or recorded work position. Is controlled by software that optimizes the path to the stowed or saved work position based on machine stability.
The X660SJ comes standard with a Kubota diesel engine and an environmentally friendly Li-ion battery and AC drive system option is available as is JLG’s new bi-energy option. This alternative equips the JLG compact crawler boom lift with two full-sized independent power sources, combining an emissions-free Li-ion battery pack with a dependable diesel engine, enabling operators to choose the best power source for the application. The units come standard with fully synthetic biodegradable hydraulic fluid so it can be used with confidence in environmentally sensitive areas.
Like JLG’s other compact crawler boom lift models, forklift pockets for loading and unloading for transportation are standard. Air/water/power lines to the platform, non-marking tracks for work on sensitive flooring, integrated front and rear LED lights for visibility and SkyGuard SkyLine enhanced control panel protection also come standard on the X660SJ.
This new model also has similar components and serviceability features to JLG’s entire compact crawler boom lift product family, including the enclosed powertrack design, which protects machine components by reducing debris impact.
“With the X660SJ, productivity is a top priority,” concludes Patterson. “This compact, low-weight straight-jib model will transform how facility and construction professionals get work done at height, indoors and outdoors.”
