<p>A heavy duty lift bed trailer (20) adapted for inplant or highway use to transport high tonnage loads (C) on pallet frame units (26) which can be picked up or dropped off quickly without the need for additional equipment or personnel. The trailer may be coupled to a tractor vehicle (21) by means of a fixed gooseneck (23) built to a conventional fifth wheel height. It includes a plurality of centrally located hinge panels (68, 69, 70) pivotally connected between the main frame (31) and the lift bed (59) for constraining the latter to move in parallel relation to the frame between a lowered loading position and a raised transport position; an improved lift bed locking mechanism (90) for transport; a heavy duty suspension (32) adapted to equalize the load on each axle (44, 45, 46); and is capable of handling eccentric as well as laterally centered loads. </p> |
