Lift Motors

The power unit is the motor and hydraulic pump assembly that drives the lift's hydraulic cylinders, usually with an integrated reservoir and control valve. It is the component that actually raises the lift.

Match voltage, phase, horsepower, reservoir capacity, port configuration, and mounting arrangement to your existing unit. Identify the lift's make, model, and serial number and, where possible, the part number on the existing power unit before ordering.

This collection includes single-phase units at common shop voltages alongside other configurations from AMGO, APlusLift, and Challenger. The replacement must match your building's available power — you cannot substitute a three-phase unit for a single-phase installation.

Slow or inconsistent lifting, motor overheating or tripping, unusual noise, and the lift drifting down under load. Drift can also indicate cylinder or valve problems rather than the power unit itself, so diagnose before replacing.

It involves both hydraulic and electrical work on a lifting device. Many shops handle it, but the system must be properly bled, the lift function-tested through its full range, and safety locks verified before returning to service. If in doubt, use a qualified lift technician.

Using the manufacturer-specified replacement and installing it correctly maintains the lift's condition. Fitting a non-specified unit changes the lift from its certified configuration and can affect both certification standing and warranty. A non-specified unit is no longer the lift the certification was issued for.

Keep hydraulic fluid at the correct level and change it at the manufacturer's interval, keep the motor clear of dust, and watch for leaks at fittings and the reservoir. Low or contaminated fluid is the most common cause of premature power unit failure.
