Abstract

A transport vehicle particularly useful for industrial uses and adapted to pick up, carry and subsequently dump a load-carrying receptacle comprising a U-shaped wheel-carried outer frame towed by a tractor which supports an inner U-shaped frame for picking up the receptacle. Vertical rear hoist cylinders elevate the inner U-shaped frame and rotate it about retracted dump cylinders to raise the inner U-shaped frame from an initial horizontal ground-level position to a forwardly tilted travel position. The dump cylinders can then tilt the inner frame about a pivot axis at its rear end to empty cargo from the receptacle. Latching and restraining mechanisms are provided to prevent the receptacle from tipping backward and sliding rearwardly with respect to the inner frame when dumping its load. The latching and restraining mechanisms are gravity-controlled and become inoperative when the inner frame resumes its forwardly tilted travel position.
