This power unit is designed specifically for use on 2 and 4 post auto hoists. This is for
raise-hold-lower of the lift, with manual control of the lowering speed. A pushbutton, mounted on the unit, starts the motor to raise the lift. The unit features a fixed relief valve, so the lift cannot be overloaded, but (depending on the cylinder size) can be used on most 7000 to
9000 lbs. (3175 to 4082 kg) capacity lifts. Cartridge valves are used, allowing easy field service and interchangeability. Air motor driven models also available.
