PURPOSE: A grit suction module is provided to easily collect grit remaining in the workspace inside a hull and to minimize damage even if a platform is shaken. CONSTITUTION: A grit suction module comprises a grit suction nozzle(110), a frame unit(120), and a joint(160). The grit suction nozzle is connected to a suction pipe which inhales air. The frame unit lifts, yawing-rotates, or rolling-rotates the grit suction nozzle. The joint is connected to an arm installed in a platform. |
