<p>A dual side-dumping truck and trailer combination is disclosed utilizing a dolly-type trailer (130) and a frameless material-hauling bed (10). The bed is suspended on bunk assemblies (20, 30) mounted rotatably on bolsters (70, 80) on the truck frame (110) and the trailer frame (140). Hinge mounting means (40) on the ends of the bunk assemblies (20, 30) enable selective tilting of the bed (10) to one side or the other. The dolly-type trailer (130) provides increased manoeuvreability and improved safety factor by enabling jackknifing while dumping.</p> |
