Abstract

Mounted support arms affixed to a fifth wheel pinbox and formed to receive booms provide a sturdy framework for a winch mounting plate. The winch actuates a hitch-hoisting cable which may be attached to a truck hitch to lift it from the bed of a truck and then lower it to a storage location. The hitch hoist may have two mounting arms, two booms, and a winch on a plate with width variability built into the bolting slot patterns. The booms extend from the mounting arms near the winch plate to form an obtuse angle between the booms and the arms. From the horizon, the angle may be viewed to be that of approximately forty-five degrees (45°). An axle is affixed near the end of the booms and holds a cable wheel which guides a cable and hook to raise and lower the hitch with the winch.

an arm combination,
wherein the arm combination has a proximal end and a distal end,
the proximal end of the arm combination affixes to the gooseneck trailer pin box,
the distal end of the arm combination terminates in a receiver,
a boom assembly,
the boom assembly inserts into the arm combination receiver and extends at a substantially vertical angle,
a winch mounted on a plate,
the plate being secured near the distal end of the arm combination,
a cable secured in the winch,
the cable being supported by and tracking with the angle of the boom assembly and extending a distance to reach the hitch,
