Abstract: A rail member is supported longitudinally along both sides of the deck of a truck or trailer and includes a plurality of strap hook anchoring locations at spaced positions therein. Each anchoring location is defined by a pair of hook opening extending downwardly through an upper flange of the rail member. Cargo securing straps or chains are anchored onto the respective anchoring locations using an anchor member having an upper body portion defining a tie-down opening and a pair of lower hooks which can be hooked into the pair of hook openings of a selected anchoring location. The upper body portions spans between the two hook openings so as to prevent passage of the upper body portion through the hook openings while the cargo straps or chains remain slack.

Abstract: A dry goods bulk trailer for transporting fluidic dry goods includes a frame supported on rear wheels and arranged for connection at a front end to a towing vehicle. A containment structure on the frame assembly for supporting the fluidic dry goods therein includes front and rear slope wall assemblies which slope downwardly and inwardly towards centrally located bottom discharge hoppers. Each slope wall assembly includes an inner panel, an outer panel and at least one internal structural member joined between the panels to provide sufficient structural support to enable the slope wall assembly to be only supported on the trailer frame about its perimeter. The inner panel is joined to the structural member without fasteners so that the inner surface thereof is substantially uninterrupted for easier cleanout. The outer surface of the outer panel is uninterrupted by frame members to minimize collection of snow and ice thereon.
