ABSTRACT:
A portable crane operable between a first, extended position for lifting loads and a second collapsed position for transportation includes a handle having first and second ends. A boom having first and second ends is provided such that the first end is pivotally interconnected to the first end of the handle. The boom extends outwardly from the first end of the handle in the crane first position and is disposed parallel to the handle in the crane second position. Structure is provided for supporting the handle first end and extends in a direction opposite the boom in the crane second position. A pair of outriggers anchor guy cables on the first end of the handle. A cable extends between the handle second end and the boom second end for receiving a load, such that as the cable is retracted, a load is lifted toward the boom second end.
