To provide increased traction and a smoother ride for its Model GS-3390, GS-4390 and GS-5390 rough-terrain scissor lifts, Genie is making its patented oscillating axle available as an option on these units. The axles are engineered specifically for scissor lifts, says the company, and feature dual-mode oscillation, which "allows the axles to navigate rough terrain while maintaining four-wheel contact with the ground, and combines maximum traction and power for driving when the platform is lowered."
