ABSTRACT:
A telescoping hoist assembly normally stored in the rear bumper area of a pickup truck includes a boom telescoping into and out of a mast pivotally anchored at one end of the pickup bumper structure. A power winch operated by the pickup electrical energizer is axially mounted on the outward end of the boom. With boom extended out of the mast the cable is connected with the anchored area of the mast for a hoist self erecting action interrupted, when the mast is vertical, by stop members at the base end of the mast. A mast stored jack structure supports hoist loads independently of the pickup suspension system.
