JLG self-levelling boom lift automatically adapts to terrain on slopes up to 10 degrees
JLG Industries' JLG 670SJ self-levelling boom lift is now available in North America. Equipped with JLG's patented self-levelling 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-foot platform height.
The 670SJ's self-levelling 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.
"Engineered with the world's first fully integrated, self-levelling chassis, the 670SJ is a game-changer for the aerial equipment industry," says Shashank Bhatia, vice president of engineering for MEWPS, JLG. "On the underside of the machine, you can see that it 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 not only allows the machine to continuously and seamlessly self-level, but it does so without requiring operator inputs."
The 670SJ also features three operating modes to maximize transportability on site or on the road. Self-levelling 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. 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.
JLG's self-levelling technology offers a host of benefits for machine operators and their support crews, including reducing (and in some cases even eliminating) the prep work required to level the work area. That means no more pre-grading the site or constructing labourious cribbing before getting to work.
It also eliminates the trial and effort of repositioning a boom lift to find a level work area. This helps operators get into position and up to the work area quicker, maximizes reach capabilities and reduces the need for larger, higher reaching lifts onsite as a backup for added reach when uneven ground conditions exist.
Operator comfort and safety were also key factors in the development of this product. The 670SJ provides a smoother ride as operators travel across a job site due to its advanced control system. It is designed to continuously adjust to the terrain to keep the platform level and minimize movement, thereby reducing operator fatigue, as well as the potential for objects to bounce around and/or out of the platform.
The JLG 670SJ self-levelling boom lift offers a 73-foot work height and 57 feet of horizontal reach, with 550-pound unrestricted and 750-pound 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.
As one of the latest models in the R2-Series excavator lineup, the Bobcat® E88 delivers durability, performance and quality for more productivity. Technically speaking, it's a compact machine, but it brings big performance with its redesigned engine and optimized lift performance, plus undercarriage and counterweight improvements. All these enhancements make this excavator one of the highest-performing models in its size class. With impressive over-the-side lift capacity, you can dig with greater confidence over the side of the machine. Put it to the test against similar models from other manufacturers. You'll see that the E88 can outwork the competition.
