Wabash Aluminum Drop Decks
Superior Main Beam. Lower Maintenance.
The two-piece, welded main beam design eliminates the need for mechanical fasteners by welding on the neutral axis—where bending stress is minimal. Unlike bolted designs, this beam has no fasteners that loosen over time, minimizing maintenance.
Less Weight. More Freight.
Floor crossmembers weld directly to the main beam, side rail, and floor to create a super-stiff structure—eliminating knee braces for a lighter trailer with less maintenance and increased payload efficiency.
Greater Flexibility. More Loaded Miles.
The Lock-Rite® multi-position tie-down system provides unmatched versatility—allowing loads to be secured either at the trailer’s center or along the outer siderails using straps or chains. Its patent-pending design maximizes load security and uptime.
Better Highway Visibility.
The enhanced lighting system includes three stop/tail/turn lamps and five dual-function side marker lights that also act as turn signals—improving highway safety and motorist awareness from every angle.
