ABSTRACT:
A vehicle (10) is disclosed which includes a power unit (14) and an end dump trailer (12). The legal payload of the trailer (12) is increased by using a sliding pedestal (30) mounting rear tandem wheel unit (18). The pedestal (30) is slidable to a forward position for dumping and to a rearward position for traveling on a public highway. The unit (18) includes a pedestal (30) slidable along the frame (33) of the trailer body (16) on polyethylene pads (34). Cooperating frame wedges (38, 40, 42) and pedestal wedges (44, 46) wedge the pedestal (30) in the forward and rearward positions. Locking wedges (58, 60) lock the pedestal in the forward and rearward positions. Polyethylene guide blocks (68) align the pedestal (30) with the frame (33).
