ABSTRACT:
A pair of substantially identical elongated steel lift rails which are adapted to be mounted upon the ends of the rear frame members of a tractor of the fifth wheel coupling type. Each lift rail comprises an elongated steel member which slopes downwardly at its rearmost end and, when mounted on the frame member, presents an upwardly inclined surface. The lift rails facilitate the coupling of an associated trailer onto the tractor by, upon rearward movement of the tractor, lifting the trailer gradually to the proper height for coupling. The invention prevents damage to the trailer and tractor in those frequent cases where the boxcar of the trailer may become positioned below the normal coupling height.
