ABSTRACT:
A bottom dump vehicle has a driver's cab mounted on the front portion of the vehicle and an engine mounted on the rear portion thereof. The vehicle has a front and a rear axle, each of which mounts a plurality of wheels. A drive train extends from the engine to both the front and the rear axles so that all wheels of the vehicle are driven. A load-carrying hopper is mounted on the rear portion of the vehicle to receive loads of earth, for example. The drive train includes a drive shaft that extends lengthwise of the rear portion of the vehicle through a tunnel member located at the bottom of the load-carrying hopper. A pair of dump doors defining at least part of the bottom of the hopper are located on opposite sides of the tunnel member and are mounted so as to be movable away from each other to provide a dump opening in the bottom of the hopper. When the dump doors are in a closed position, they butt against opposite side walls of the tunnel member.
