Lifting equipment we examine
Why your vehicle jack needs LOLER examination
A trolley jack, bottle jack or other vehicle jack used in a workshop is lifting equipment under LOLER, so it is thoroughly examined at least every twelve months by a competent person independent of whoever maintains it. It lifts a load rather than a person, which sets the interval, but it carries a particular risk: people are tempted to leave a vehicle on it and work underneath. A jack is a lifting device, not a support, and the examination is partly about proving it lifts safely and partly about reinforcing that line.
The heart of the examination is the hydraulics. A competent person proves that the unit builds pressure and, more importantly, holds it under load, because a jack that bleeds down while a vehicle is raised is the classic and dangerous failure. Then the lowering valve, which has to bring the load down under control rather than dropping it, the overload or safety relief valve, the lift arm, the saddle or cup that meets the jacking point, and the pivots, wheels and handle. None of that changes the rule: once a vehicle is up, it goes onto axle stands or props before anyone goes near it.
