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.
Claims11
A semi-trailer for hauling freight loads, comprising:
- longitudinally extending load bearing support frame means;
- a series including a multiplicity of cross support members extending transversely of and supported above said support frame means and extending substantially the entire width of the semi-trailer for receiving and supporting freight loads, said semi-trailer being free of any decking overlying said cross support members;
- said cross frame members defining spaced therebetween for receiving means such as a fork lift for loading and unloading freight loads;
- and suspension means for isolating the effects of road vibrations from said support frame means and freight loads supported thereby.
A semi-trailer for hauling cargo, comprising:
- longitudinally extending load bearing support frame means;
- a multiplicity of transverse support members fastened to an upper surface of, and generally uniformly spaced along the entire length of said longitudinal support frame means for receiving and directly supporting cargo and facilitating cargo loading and unloading procedures;
- suspension means comprising an axial carriage pivotally connected to said support frame means and air-spring means for isolating the effects of road vibration from the support frame means and allowing cargo to be safely transported without sustaining damage.
