Portable lift collapses to a low 3' profile and raises up to 17'. Weighing only 85 lbs., lift is easily positioned under race car to raise off the ground simplifying tire changes and chassis tuning. Strong 14 gauge steel lift will support up to 2,400 Lbs. Complete system includes a 110V AC 3/4HP hydraulic pump with cord and plug, hydraulic cylinders with down assist canisters, 1' bolt on risers for cars with raised frame rails, safety struts to lock raised lift in place, assist handle and 20' of hydraulic quick connect hose to attach pump to lift. The pump provides power up/gravity down operation and can be mounted either horizontally or vertically, typically mounted to trailer or a hand cart. A push-button on the motor starts the unit to raise lift. To lower, a manually operated release valve is used for finger-tip control of lowering speed. Pump is compatible with hydraulic fluid, ATF, 10W30 or 10W40 oil (not included). Assembly is required, all hardware included.
