ABSTRACT:
A device for aligning the tongue and hitch first portion on a trailer (trailer hitch) with the receiver and hitch second portion (ball) on a towing vehicle, and for lifting the trailer hitch on and off the ball. The device comprises a vertical post on the towing vehicle in front of and in close proximity to the ball. The post has a pivotal arm which can rotate from a vertical position to a rearwardly inclined position. The post has a cable guide at or near its top surface. The pivotal arm also has a cable guide at or near its top surface. The cable guides are for receiving and guiding a cable connected to a winch on the tongue of the trailer. The tongue of the trailer also has a cable guide in front of the winch near the front end of the tongue. The invention has two (2) modes of operation (please refer to FIGS. 1 and 2): 1) on-loading the trailer hitch onto the ball; and, 2) off-loading the trailer hitch from the ball. During on-loading, slack cable from the winch is directed through the tongue cable guide, over the pivotal arm cable guide, over the post cable guide and is connected to a cable hook receiver low on the post. During off-loading, the post cable guide is not utilized and the cable passes from the winch, through the tongue cable guide, over the pivotal arm cable guide and is connected to the cable hook receiver or to the vehicle.
