Hydraulic ship scraper is a kind of hydraulic driven double disk brush cleaning equipment with large torque and low rotation speed, which is a kind of mechanical friction cleaning equipment. By rotating the disc brush, it creates friction on the surface of the ship, which cleans it up. The boat scraper can be operated by a single person without the need for large slings. When the brush is facing the hull, it can rotate in both directions and balance the torque, which can effectively reduce the labor intensity of the operator.
