ABSTRACT:
A lightweight, flatbed semi-trailer vehicle constructed substantially entirely of lightweight, high-strength structural members and capable of being utilized in conjunction with a truck tractor. The vehicle does not require flooring or decking and comprises at least two longitudinal spaced apart support members, and a plurality of transverse support members bolted to the upper surfaces of the longitudinal support members for use as a lowermost tier of dunnage. A stress plate provides structural rigidity to the design and serves as a second means of interconnecting the longitudinal support members. The vehicle also is equipped with unique fluid suspension means for absorbing and dampening road vibrations and offsetting any adverse effects caused by the elimination of a lower tier of dunnage.
