ABSTRACT:
A dual side-dumping truck and trailer combination utilizing a dolly-type trailer and a frameless material hauling bed. The bed is suspended on bunk assemblies mounted rotatably on bolsters on the truck frame and the trailer frame. Hinge mounting arrangements on the ends of the bunk assemblies enable selective tilting of the bed to one side or the other. The dolly-type trailer provides increased maneuverability and improved safety factor by enabling jackknifing while dumping.
