JLG Industries has introduced the JLG 670SJ self-leveling boom lift, featuring JLG’s self-leveling technology. The 670SJ is engineered to automatically adapt to terrain on slopes up to 10 degrees in any direction, while driving with full functionality at a 67-ft platform height.
The 670SJ’s self-leveling technology is designed to adjust the boom lift’s chassis to the ground conditions — rather than having to adjust the ground conditions to the machine. This allows the 670SJ to navigate uneven terrain while driving at height from one job to the other without lowering the boom, leading to significant productivity gains throughout the workday.
The 670SJ has four independent axles, each controlled by its own smart hydraulic cylinders. These enable each wheel to separately follow the contour of the terrain and stay in constant contact with the ground. This allows the machine to continuously and seamlessly self-level, without requiring operator inputs.
The 670SJ includes three operating modes to maximize transportability on site or on the road. Self-leveling mode enables the machine to work at full height, with full functionality, on slopes up to 10 degrees. Travel mode can be used when the boom is stowed to move across the job site at a faster rate of speed. And, shipping mode allows the entire machine to be lowered once in position on a truck, reducing its travel height.
All of these features are made possible through the machine’s advanced control system. This system continuously receives performance data from various sensors on the machine, then displays the information through a digital display and selectable screen interface in the platform during operation, ensuring users are more knowledgeable about what’s going on at ground level while working at height.
The 670SJ offers a 73-ft work height and 57-ft of horizontal reach, with 550-lb unrestricted and 750-lb restricted capacities. It also features JLG’s automatic, single sensor load sensing system with zero-load calibration. This functionality keeps the machine within the allowable work envelope by limiting range depending on the platform load.
