The invention provides a wide tail of a dumper. The wide tail is made of a steel plate through one-off forming, one end of the steel plate is folded continuously and vertically to form a hollow supporting part, a sealing opening of the supporting part is fixed through welding, in the using process, a boxcar turnover mechanism is fixed to the supporting part, the other end of the steel plate extends and is turned up to form a wing surface connected with the tail end of a frame, and all edgefold angles are in smooth transition. The wide tail of the dumper is made of the steel plate through one-off forming, welding portions and the assembly work procedures are reduced, materials are saved, cost is reduced, and the working efficiency is improved; all the edgefold angles are in smooth transition, strength of a steel pipe is improved properly, and the product quality is improved. The wide tail made of the structural section can ensure manufacturability, is high in strength and capable of being widely used for wide tail type tip-back dumpers.
