The invention discloses a stone dumper provided with symmetrical type stone cabins. The stone dumper comprises a dumper body, a stone conveying unit and an oblique pipe falling unit. A pipe-holding compensation device of the oblique pipe falling unit is arranged at the side edge of the dumper body, and provided with a material falling pipe, the stone cabins are symmetrically arranged on the two sides of a midship control cabin correspondingly, dynamic positioning system cabins are further symmetrically arranged on the two sides of the midship control cabin correspondingly, the stone cabins canoperate independently, stones can be automatically unloaded to the stone conveying unit, then the stones are conveyed to the material falling pipe through the control cabin, and the dynamic positioning system cabins and the pipe-holding compensation device can position the dumper body and the material falling pipe correspondingly; and whereby, the stone dumper provided with the symmetrical type stone cabins can complete high-precision stone dumping operation, and has the advantage that materials, time, labor and money are saved.
