ABSTRACT:
A mechanism raises and lowers a tailgate provided on a dump box of a dump truck, trailer, or similar vehicle. The dump box has an open end and is supported on the frame for movement between a lowered position for storing and transporting items and a raised position for dumping the items out of the dump box. A tailgate is supported on the bump box for movement between a closed position, wherein the tailgate closes the open rear end of the dump box, and an opened position, wherein the tailgate is spaced away from the open end of the dump box. A double cylinder assembly extends between the dump box and the tailgate for selectively moving the tailgate between the closed and opened positions.
