Abstract
A frameless dump trailer is provided. The frameless dump trailer includes a forward body portion and a rear body portion. Each body portion is formed from two or more panels joined together with butt-joint welds. The forward portion is first formed by welding planar sections together. After the body portion is formed from the plurality of planar panels, the larger planar portion is rolled in a rolling system to define the arcuate shape of trailer body. Then, the forward and rear body portions are welding together with a transversely extending butt-weld.
