ABSTRACT:
A towing assembly includes a mounting member fixed to the frame of a towing vehicle. The mounting member includes two support bars in spaced relation that are fixed perpendicularly to two cross bars that are in turn fixed to the frame of the towing vehicle. Both the support bars and the cross bars take the form of angle irons, with the horizontal legs of the support bars fixed to the horizontal legs of the cross bars. A motion assembly is coupled to the vertical legs of the support bars. The motion assembly comprises a first vertical tube coupled to the support bars and a second vertical tube associated with the first vertical tube for uniform vertical translation. A pair of roller assemblies facilitate the uniform vertical translation of the second tube. The roller assemblies are offset from one another both in a vertical plane and a horizontal plane. A horizontal tube is coupled to the second vertical tube and vertically translates therewith. A load bar that supports the towed vehicle is received within the horizontal tube and thus lifts the towed vehicle in response to vertical translation of the second vertical tube. The motion assembly is utilizes a motorized screw actuator that may be actuated from a remote location.
