Abstract
A bulk material container, such as a trailer, includes an improved cross brace and top rail system including roller-type cross brace assemblies. The rear and center cross brace assemblies advantageously include a support tube, an outer loosely mounted roller, and two mounting brackets. The tube serves as the lateral support for the trailer; the ends being held in brackets attached to the top rails. The roller is mounted loosely over the tube and is free to rotate and/or to be lifted vertically, thereby preventing tightly packed bulk cargo material from becoming lodged against the braces during the unloading process. The top rails are extrusions with different portion thicknesses designed to minimize the weight while still providing sufficient strength to withstand the forces exerted during loading.
