Abstract

A carrier for lifting, transporting and dumping a large load box or the like is provided including a wheeled trailer having a plurality of frame members and a forwardly projecting tongue for pivotal connection to a tractor. A first hydraulic cylinder is provided for raising and lowering the trailer frame with respect to the trailer wheels. A pair of laterally spaced jaw members are secured to the rear cross frame member of the trailer to receive transverse hinge pins secured to the underside of the load box adjacent its rear end and a latch plate is provided to lock the transverse hinge pins in the jaws. A tilt frame is pivotally pinned to the rear cross frame member about a tilt axis coaxial with the hinge pins when they are locked in the jaws and a second hydraulic cylinder interconnects the forward end of the tilt frame for pivotally raising the tilt frame and the load box about their coaxial pivot pins whereby the forward end of the load box is elevated first into transport position and, when the second cylinder is further extended, into full dump position. Abutting surfaces on the latch plates and the rear underside of the load box prevent the tendency for the load box to tilt further as the load is discharged rearward of the load box hinge pins.
