Abstract
A truck for transporting and dumping a load which includes a vehicle with a fifth wheel configured to pivot about a horizontal first axis from a first extreme to a second extreme. A dump trailer hitched to the fifth wheel includes an elongate load bed. The trailer also includes a hitch base for coupling the trailer to the fifth wheel, an arm pivotally linking the hitch base and bed, and a load bearing lift mechanism. A lift mechanism selectively tilts the trailer bed to dump a load. The lift mechanism has an upper end portion connected to the bed and a lower end portion pivotally connected to the hitch base. The lower end portion is configured to pivot about a second axis generally parallel to the first axis. The second axis is horizontally displaced from the first axis so that loading of the fifth wheel by the trailer substantially maintains the fifth wheel in one of the first and second extremes during dumping and avoids the need to lock the fifth wheel during transport.
