Abstract
A towable trailer has a load floor supported by air springs on a torsion box suspension system. The load floor consists of a plurality of preformed panels comprised of a plate section and a plurality of I beam members. Adjacent panels are interconnected with a tab and slot structure and then secured as a unit by a pair of angle beam side rails. The suspension system includes a pair of spaced parallel transverse beams extending between and secured to a pair of trailing arms which are pivotally mounted on brace members secured to the underside of the load floor and the front of the trailer. A pair of plates are secured to respective ends of the transverse beams adjacent the trailing arms. Cross beam members are positioned between and secured to the plates and the transverse beams. The trailer wheel are supported on wheel support arms which are secured to and extend upwardly from each trailing arm to position the center of each wheel above the load floor of the trailer. The angle beam side rails are connected with a vertically spaced top beam by fore and aft vertical beams and a side skin.
