Abstract
The present invention is a self-locking folding crane apparatus that can be installed onto any pivot shaft and held in place by small positioning devices such as clamps, slip-rings, bolts, shaft collars, pins, and other mechanical means; a substantial base is not needed to support the hoist as long as the pivot shaft is able to do so. The resulting hoist can be recoverably installed and optionally left on a vehicle or cart while it is in either an operative or stowed state. Unlike all other portable cranes that were found in prior art either singly or in combination, the present invention requires no assembly or disassembly between uses.
