Abstract
A bottom dump arrangement attached to a body which provides a goods-holding space, the body resting on an undercarriage and including at least one pair of adjacent doors having remote edges, the doors being pivotally attached at their remote edges for swinging movement in a curved path transverse to the body and perpendicular to the remote edges, the free edges of the doors facing toward each other abutting each other in closed position of the doors, the arrangement also including guide paths that cooperate with the body to lift the body relative to the undercarriage, a linkage assembly pivotally connected between the doors and the body for permitting the body, when lifted by the guide paths, to become inclined to the pivotal axes for the doors in a vertical plane, which is parallel to the pivotal axes of the doors and perpendicular to the plane that the undercarriage rests on.
