Lift drifts down when held up

When your car lift slowly drifts downwards after being raised and parked at height, it's a clear indication of an internal hydraulic leak or a problem with a pressure-holding component. This issue affects all types of automotive lifts, from two post lift to four post lift models, and directly compromises safety. The most common culprits include a faulty or contaminated check valve (allowing fluid to backflow from the cylinder to the reservoir), internal leaks past the seals of the hydraulic cylinders (worn or damaged piston seals), or a lowering valve that is not fully seating or is malfunctioning, permitting a slow escape of fluid. Less commonly, a relief valve that weeps fluid at slightly below system pressure can also contribute to drift.

The impact of a drifting vehicle lift is severe, primarily concerning safety. Servicing a vehicle on a lift that cannot reliably hold its position is extremely dangerous, posing a significant risk of injury to technicians and damage to the vehicle. Such a lift becomes unusable for any extended service, leading to significant downtime, lost productivity, and potential liability issues for your workshop. Even a slow drift requires constant monitoring or re-lifting, which is inefficient and places unnecessary wear on the pump and motor. Prompt diagnosis and repair of the underlying leak are crucial for restoring the lift's safe and reliable operation.

Eounice car lifts are engineered for superior load holding and stability, designed to prevent unintended drift. Our scissor car lift, four post lift, and 2 collumn lift models feature high-quality hydraulic cylinders with durable, precision-engineered piston seals that effectively contain fluid pressure. Eounice hydraulic power units incorporate robust check valves designed for reliable, positive sealing to prevent fluid backflow. Our lowering valves are manufactured with precision to ensure full closure when the lift is held. This meticulous attention to hydraulic component quality and system design ensures that each Eounice vehicle lift maintains its height securely and safely for extended periods.
