Challenger designed its 30,000 lb. to 60,000 lb. lifts as an economic high capacity lifting solution in a traditional 4-post design. Diamond plated anti-skid runways and ramps provide for positive vehicle traction. The synchro-power system has dual heavy-duty lift cylinders as well as lever controls, which provide variable or synchronous power to the front and/or rear suspension of the lift, making it perfect for lifting large axle vehicles with heavier front or rear ends, including waste trucks and other construction trucks. Features: - 30,000 lb. capacity 4-post - 310" to 430" max wheelbase - 32" wide runways aid for drive-on confidence - 10 lock positions provide maximum head room for working underneath vehicles - Single-point air actuated lock release allows technicians to disengage column locks simultaneously - Diamond-plate approach ramps for positive vehicle traction
