Abstract
The flat, load-carrying head of the jack may be adapted through a set of special adapter components for lifting, lowering and transporting irregularly-shaped objects such as heavy, unwieldy truck transmissions, differentials and power dividers notwithstanding their incompatibility with the flat surface of the platform. The components may be independently adjusted in a multiplicity of directions totally by hand and may be arranged in a variety of relationships such as to accommodate virtually any configuration presented by the particular object being handled and to do so relatively quickly without the use of special hand tools, certain of the components being especially suited for providing a low profile to the supporting head and the particular object being supported so as to facilitate manipulation of the jack in close quarters and under low overhead obstructions.
