ABSTRACT:
This hitch assembly includes a frame which is fixedly attached to the rear of a truck and extends widthwise of the truck to provide upper and lower horizontal rails. A transverse carriage having upper and lower roller assemblies engageable with the rails is mounted to the frame and moved laterally relative to the frame by means of a ram assembly. The ram assembly includes a piston extending from end-to-end of the frame and a cylinder which is fixedly attached to the carriage and movably mounted to the piston. A vertical lift carriage is slidably mounted to the transverse carriage and is movable vertically relative to the frame by a ram assembly. The vertical carriage includes a hitch ball for attachment of a trailer tow bar and the transverse and vertical carriages provide the hitch connection and the tow bar with vertical and laterally horizontal components of movement. A support is provided for the vertical carriage so that when desired the rear of the truck can be raised and moved both transversely and vertically relative to the hitch connection while the trailer is stationary to provide additional movement.
