JLG 670SJ Self-Levelling

If you want to eliminate the hidden bottlenecks on a chaotic construction site, the JLG 670SJ is the ultimate solution. Standard boom lifts require flat ground to operate safely, forcing operators to constantly adjust, reset, or wait for earthmoving equipment to level the area. The 670SJ circumvents this entirely with its advanced, fully integrated self-levelling chassis.

As your operator traverses slopes, ruts, or uneven ground up to 10 degrees, the independent suspension system continuously recalculates and adjusts. This keeps the superstructure completely level, even when driving with the boom fully extended at a 67-foot platform height. This translates to an incredibly smooth ride, significantly less boom bounce, and a massive reduction in repositioning downtime. Combined with a versatile dual-capacity rating (up to 750 lbs) and a responsive 6-foot articulating jib, it sets a completely new standard for site efficiency.

Key Features

• Smart Self-Levelling Technology: Automatically levels the machine’s superstructure on slopes up to 10 degrees in any direction, even whilst driving at height.
• Dual-Capacity Envelope: Smart load-sensing automatically switches between a 550-lb unrestricted capacity and a heavy-duty 750-lb restricted capacity zone.
• Continuous Travel at Height: Operators can safely drive the machine whilst fully elevated, maintaining total focus on the task rather than setup sequences.
• Versatile Suspension Modes: Includes standard mode for faster travel with the boom stowed, and shipping mode to lower the suspension height for easy transport.
• Articulating Jib Integration: Equipped with a 6-ft (1.83 m) jib giving precise “up-and-over” manoeuvrability around structural steel, conduits, and rooflines.

Key Benefits

• Drastic Reduction in Labour Downtime: No more wasting time cribbing wheels, grading dirt, or performing tedious trial-and-error manoeuvring just to get a level chassis.
• Enhanced Tool & Material Security: The ultra-smooth self-levelling ride minimises platform sway, keeping tools, hardware, and materials securely in the basket rather than rattling around.
• High-Margin Fleet Demands: Because this technology solves a massive real-world pain point, the 670SJ commands premium hire rates and experiences incredible fleet utilisation among Tier-1 contractors.
• Reduced Operator Fatigue: The constant automatic adjustments create a significantly more stable and secure working environment, boosting operator confidence and stamina during full-day shifts.
