Abstract: A side dump body having an increased carrying capacity when compared to conventional side dump bodies with the side dump body being pivotally movable between transport, loading and dumping positions. The side dump body has an open upper end which is directed upwardly when the side dump body is in its transport position. When the side dump body is in its loading position, the open upper end of the side dump body is directed upwardly and laterally towards one side of the wheeled frame upon which the side dump body is pivotally mounted. When the side dump body is in its dumping position, the open upper end of the side dump body is directed laterally and downwardly from the side of the wheeled frame.

Abstract: A side dump body including a plurality of side dump body units pivotally mounted on a truck or trailer frame. Each of the side dump body units may be individually pivotally moved from a transport position to a dumping position whereby the contents of the dump body units may be dumped from the side of the truck or trailer.

Abstract: A side dump trailer comprising a trailer body pivotally mounted on a wheeled frame to enable the material within the trailer body to be dumped from one side of the trailer.
