ABSTRACT:
A dump hopper for a road sweeper includes a dump door, a debris guide chute, and an actuating mechanism for pivoting the dump door and debris chute between travel and dumping positions. The dump door is sandwiched between a hopper and the guide chute in the travel position and seals a debris discharge opening of the hopper. A pair of fluid cylinders are pivotally connected to the dump door and the guide chute and cooperate with cam and cam followers to hold the dump door in sealed relationship to the debris discharge opening until the debris guide chute has been fully deployed.
