Abstract
A monolithic dual-purpose trailer for transporting cargo includes a frame including two longitudinally extending side rails and a central reinforcing member in the form of an engineered truss is located between the two side rails. Wheels are mounted to the frame. A deck including a load bearing surface with a grate is formed on the frame. Hoppers are positioned below the grate. The frame is formed as one solid welded unit. The deck has a portion formed of flat aluminum. A perimeter frame rail is located around the deck. The trailer can transport multiple types of loads and does not have to be converted from one mode to another and additionally has reduced longitudinal flexing.
