JLG 670SJ Self-Leveling Boom Lift Will Change Work at Height

JLG Industries Inc. has launched the JLG 670SJ, a self-leveling boom lift that will change the way people work at height.

Now available in North America, the 670SJ features JLG’s patented self-leveling technology that automatically adapts to slopes of up to 10° in any direction while driving with full functionality at 67’ platform height. 

“We are extremely excited to bring this transformational innovation to market,” said Robert Messina, senior vice president of global product development and product management, JLG. 

The 670SJ’s self-leveling technology adjusts its chassis to ground conditions — rather than having to adjust ground conditions to the machine. That allows the 670SJ to navigate uneven terrain while driving with the platform at height, a significant boost for  productivity.

“Engineered with the world’s first fully integrated, self-leveling chassis, the 670SJ is a game changer for the aerial equipment industry,” said Shashank Bhatia, vice president of engineering for MEWPS, JLG. 

Bhatia explained that each of the lift’s four independent control arms is operated by its own smart hydraulic cylinders. That arrangement lets each wheel follow the contour of the terrain separately, so it stays in constant contact with the ground. “It not only allows the machine to continuously and seamlessly self-level. It does so without operator input,” Bhatia said.

The 670SJ also offers three operating modes to maximize on-site travel and on-truck  transportability. 

Self-leveling mode enables the machine to work or travel at full height, with full functionality, on slopes up to 10°. 

Travel mode lets the lift travel faster when the boom is stowed. 

And shipping mode reduces transport height by allowing the entire machine to be lowered once in position on a truck. 

These features are possible because of the advanced control system. It continuously receives performance data from sensors, then displays the information on a digital display in the platform, ensuring users know more about what’s going on at ground level while they’re at height. 

“Advanced doesn’t mean complex when it comes to the 670SJ,” says Nate Hoover, director of product management and marketing for boom lifts, JLG. “While we’ve upgraded the display, the controls are similar to standard JLG booms, minimizing the learning curve.”

JLG’s self-leveling technology offers a host of benefits for machine operators and their support crews. They include reducing (and in some cases even eliminating) the need to level the work area. That means no more grading or constructing laborious cribbing before getting to work.

It also eliminates the time and effort of repositioning a boom lift to find a level work area. That helps operators get into position and up to the work area quicker, maximizes reach, and reduces the need to have larger, higher-reaching lifts on site as a backup for added reach when uneven ground conditions exist.


Operator comfort and safety are also key features of this lift. The 670SJ provides a smoother ride as operators travel across a job site thanks to its advanced control system. It’s 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 in the platform — or out of it.

The JLG 670SJ self-leveling boom lift offers 73’ work height or 57’ horizontal reach, with 550-lb. unrestricted and 750-lb. restricted capacities. 

It also features JLG’s automatic, single-sensor load sensing with zero-load calibration that keeps the machine within the allowable work envelope by limiting range based on the load on the platform. 

“The term innovation is thrown around so frequently in today’s day and age,” said Messina. “However true, game-changing innovation that improves safety and productivity like the JLG 670SJ self-leveling boom lift are few and far between.”
