| 摘要 |
A trailer frame structure of substantially side by side longitudinally extending generally gable shaped solid web truss members which generally incline upwardly from a hitch to a body supporting rear portion while diverging toward the rear portion. The rear portion has an upper support surface substantially parallel to the ground to receive a dump body or other load. The gable shape of the frame provides increased strength at a high stress location to resist breakage and cracking under high loads.
