ABSTRACT:
A combination engine hoist and stand for lifting and supporting an engine includes a variably oriented "H" shaped multi hinged base with frame extension capability mounted on casters and a combined hoist and stand vertical column located on the base for communicating with and supporting both a hoist and a stand via a collar disposed therebetween. The hoist includes a boom and a hoist column, the boom pivotally attached to the hoist column and the hoist column attached to the stand column via the collar. The boom is manually adjustable for length via extension elements and the boom height is adjustable by activating a hydraulic jack. A wire rope depends from the outward extending end of the boom and is manually adjustable for length by operating a winch. The boom alone or the entire hoist is removable from the stand as desired. The stand includes a stand column and a shaft that pivotally and slidably communicates with the collar on the stand column and also includes a plate for attachment to an engine. Plate and shaft may likewise be removed from the hoist and stand combination leaving only the hoist supported by the stand column and base. The invention may be used to both remove an engine from an automobile and to support an engine for repair.
