The Wave® design combines the “best of the best” features from several past and current designs into one incredible trailer. This polished end dump trailer incorporates smooth outer walls as found on our Aero-Lite end dump trailer. It uses our patented rub-rail and floor crossmember design. Also, the trailer has both an inner and outer wall as found on our SST-Aerodyne end dump or tipper trailer. Finally, the trailer maintains the superior design integrity as found on our Classic trailer for all of the components and sub-assemblies (draft arms/coupler plate, sub-frame, suspension, nose, hoist housing, tailgate hardware, electrical, air and hydraulic systems). The Wave® has better resistance to abrasion. It can incorporate insulation within the walls to hold in heat or keep out the cold. The bull-nose top rail has virtually no flat spot to hold rocks and is easy on tarps. Perhaps, best of all, this tough duty trailer is also lightweight.
