ABSTRACT:
A truck tow lift for connection to the fifth wheels of opposingly aligned trucks provides a means for towing one such vehicle with the other. The structure comprises an elongate beam member having downwardly extending standard SAE kingpins rigidly mounted on opposing ends, one of which is engaged into the fifth wheel of the tow truck, thereby becoming a horizontally pivotable and vertically rigid boom or extension of the frame thereof. Lifting means are mounted on the beam member and are connected to a lifting bar for raising the rear wheels of the towed truck off the ground. To connect the beam member to the truck to be towed, the operator positions the kingpin of the free end of the beam member over the fifth wheel of the towed truck so that it can be received therein upon lifting and attaches the lifting bar to the rear frame members. Then, the operator hoists the rear wheels of the towed truck off the ground and locks the kingpin into the fifth wheel. Conventional safety chains are attached and the truck can be towed.
