Abstract
A dump body for use on an off-highway rubber-tired haulage vehicle includes a floor, a pair of sidewalls, and a front wall. The floor includes a forward edge, a pair of side edges, and a rear edge generally defining a spillway. A plurality of load bearing beams are mounted to a bottom surface of the floor and are disposed generally parallel to and straddling a longitudinal axis of the floor. Each of the sidewalls includes a lower edge mounted to a corresponding one of the side edges of the floor, each sidewall further including a forward edge, a rearward edge, and a top edge. The front wall includes a bottom edge, a top edge, and a pair of side edges, with the bottom edge mounted to the forward edge of the floor. Each of the side edges of the front wall is mounted to the forward edge of one of the sidewalls. The floor, the pair of sidewalls, and the front wall defining a payload space, and the rear edge of the floor, the top edge of each of the sidewalls, and the top edge of the front wall cooperate to define a perimeter generally surrounding the payload space. A perimeter beam is mounted to and extends along the perimeter.
