ABSTRACT:
In this improved trailer chassis, the accessories which typically added weight without adding to the structural capacity of the trailer have been replaced with accessories which are incorporated into the structural members. The frame of the trailer chassis is comprised of a front and rear beam connecting two longitudinal side beams that incorporate a recess to capture the trailer floor decking. The axle beam mounts between the two side beams to serve as lateral support to the side beams and as a flooring beam and incorporates a open section into its section through which an axle can be mounted. The fenders for the trailer are mounted so that they contribute to the structural integrity of the frame while serving as a side enclosure in addition to a wheel well. The trailer disclosed herein also affords greater flexibility in its design by having optional cross beam members to add lateral support to the side beam members and also serve as supports for the flooring, thereby increasing the overall load capacity of the trailer.
