ABSTRACT:
Two elongated beams project forwardly and two project rearwardly from a central base portion. The pairs of beams are closer together at their front and rear ends than at the central base portion. Front and rear arms are mounted at opposite ends of the beams for limited rotational movement relative thereto. The cargo consists of a pair of prefabricated building modules, one of which is mounted on the front beams and arm, and the other on the rear beams and arm. When subjected to torsional forces, the front and rear ends of the beams can twist relative to the longitudinal axis of the semitrailer while the front and rear arms remain substantially aligned with the central base portion.
