Abstract
Abstract A garage jack, the load is lowered by depressing a pedal at the end of a pedal arm. To prevent the load from being lowered by unintentional depression of the pedal, the pedal arm is divided into an outer portion connected with the pedal proper, and an inner portion. The portions are adapted to be disengaged from each other such that in disengaged position the pedal cannot effect lowering of the load.
