A rigidified suspension is provided for a load-carrying vehicle, such as a trailer for a dual use, belly-dumping and end-dumping trailer, of the type having a frame with left and right side beams connected together and to which frame wheels are mounted through a suspension. The rigidified suspension includes left and right suspension rails, which are provided having a forward end and a rearward end and are horizontally disposed inward from and below the left and right side beams of the frame. A rear plate is fastened to said left and right side beams of the frame and extends downward therefrom adjacent to the rearward end of the left and right suspension rails. A connector brace is rigidly fastened to the rear ends of the left and right rails and to the rear plate and thereby between each other and the frame. A forward suspension brace is provided, rigidly fastening the forward ends of the left and right suspension rails to the frame and to each other. An intermediate suspension brace is provided, rigidly fastening the left and right suspension rails to the frame at a position intermediate of the forward ends and said rearward ends, so that a rigid suspension system is constructed by which a plurality of wheel axles and wheels can be connected to the frame through short vertical attachment arms.
