ABSTRACT:
Various vehicles (10, 200, 300) are provided with a rear supporting pedestal (30, 208, 316) which is movable between a forward position and a rearward position. In the forward position, the trailer unit of the vehicle can be tilted from the horizontal for dumping a payload or mounting or demounting a roll off container (318). In the rearward position, the effective legal wheel base of the vehicles is increased, permitting the gross vehicle load to be greater. The ability to vary the wheel base thus provides an increase in legal payload resulting in greater operating efficiency. In addition, a front helper lifter assembly (500) is disclosed which can be used to assist the lifting cylinders on a trailer in moving the tilting member of the trailer from the horizontal position.
