ABSTRACT:
An apparatus and method for coupling different body types to a truck, specifically interchanging between dump and trailer bodies, so that a single truck may be used to perform dump truck and tractor truck operations. The truck includes a pair of rearward extending frame rails and a mounting bracket to which a 5thwheel may be releaseably attached. The truck is adapted for carrying at least one of a 5thwheel and a hydraulic lift system and, thus, is capable of being coupled to a trailer body or dump body, respectively. The truck is changed over from having a dump body to a trailer body by lifting the dump body with its hydraulic cylinder; attaching a hoist to a dump body; lifting the dump body with a hoist; removing at least part of the weight of the hydraulic cylinder from the truck; detaching the hydraulic cylinder from the truck; removing at least part of the weight of the dump body from a coupling pin holding the dump body to the truck; removing the coupling pin; positioning a 5thwheel onto mounting brackets; securing the 5thwheel to the mounting brackets; and coupling a trailer body to the 5thwheel. The method may be reversed in order to change over the truck from carrying a trailer body to a dump body.
