ABSTRACT:
A portable engine hoist which folds into a compact storage condition. A base of the hoist is equipped with two caster wheels. Two elongated feet extend from the base and carry wheels on their outboard ends. An upright post extends from the base and carries a pivotal lifting beam at its top end. A mechanical jack operates to pivotally raise and lower the lifting beam to raise and lower an engine. An inclined brace extends from the post and carries a cross arm which may be bolted to the feet to provide a rigid brace structure. When the cross arm is unbolted from the feet, it may be pivoted until it is clear of the feet. The feet can then be pivoted upwardly and latched for storage of the hoist.
