Abstract
A jack or lift with a special fixture is provided for raising or lowering heavy and unusually shaped parts, such as crankcase and transmission guards for heavy-duty vehicles, such as track-type vehicles. The fixture on the jack engages the guard with a novel gripping or coupling arrangement for positively engaging the guard at two points. The gripping or coupling arrangement is vertically and horizontally adjustable to accommodate for different sized parts. A slope adjusting member is provided on the lift remote from the fixture to provide the third point of a three point support.
