US Patent 11584624 Multi-purpose jack apparatus and method of use

A jack apparatus has a main jack body defined by telescopically engaged outer and inner tubes, a selectively positionable clamp assembly positioned along the jack body for selective engagement with the object to which a force is to be applied, and a drive assembly located on and within the jack body. In a further related aspect a retainer is configured for being mounted on the object to be moved or lifted and for positively engaging a receiver on the clamp assembly so as to effectively lock the jack to the object being lifted such as a vehicle for safe and effective operation.
