<p>A hitching device comprises a main body portion including an upright (12), a beam (14) extending perpendiculary to the upright (12) and a pair of parallel spaced apart plates (16) to which both the upright (12) and beam (14) are connected. A hand operated winch (24) having a handle (25) is bolted to an end of the upright (12) and is operatively connected to a hook (20) by a chain (26). A pair of spaced apart and facing flanges (27) extend from the sides of the upright (12) at a location so as to receive an upper portion of the hook (20) when the hook (20) is in a hitched position (shown in phantom). Spaced apart legs (28) are provided on the plates (16) and form a surface on which a towing lug (22) can be supported when coupled to the hook (20). Each leg (28) includes an adjoining ramp (30). A pair of rollers (34, 38) are demountably and rotatably connected between the plate (16) beneath the legs (28). When the towing lug (22) is coupled to the hook (20) and the winch (24) operated to wind in the hook (20), the hook (20) is guided by the rollers (34, 38) so as to drag or pull the towing lug (22) onto the legs (28) thereby supporting the towing lug (22). The towing lug (22) is effectively captured or entrapped between the hook (20), upright (12), flanges (27) and legs (28).</p> |
