When lift cables should be replaced
Replace cables when you see broken strands, kinks, flattening, rust bleeding from inside the cable or a cable that has jumped the drum. Cables also stretch over time, which can make the cradle lift unevenly. Many technicians recommend replacing all lift cables at the same time so they wear evenly.
Signs of a failing motor or gearbox
- The motor hums but the lift doesn’t move
- The motor runs hot, smells burnt or trips the breaker or GFCI
- Grinding, clicking or squealing from the gearbox
- The lift creeps down when stopped
- Oil leaking from the gearbox
A humming motor is sometimes a failed start capacitor rather than a dead motor, which is why a proper diagnosis matters before replacing parts.
Matching parts to your lift
Replacement cables must match the drum, pulleys and lift capacity. Motors and gearboxes must match the lift’s voltage, mounting and gear ratio. If you know the lift brand and model, include it in your request. If not, photos of the motor plate and drum help.
