Apparatus and method for performing surface operations, such as cleaning and painting, on the off-vertical surface of the ship hull

摘要

The shrouded tower 32 for supporting the cantilevered work platform 40 to carry out the outer surface work of the hull (polishing and painting), is currently equipped with the techniques and equipment currently used for the movement of container ships. It is modular for economics and efficiency, including the ability to move modules around.;The supply and return line connection between the support bar with the machine, the floating gun dock and the work platform with the work tool is made easy by some fixtures and flexible connections therebetween. Another cantilever-controlled structure for mounting a workbench on a vertically movable trolley is disclosed. Preferably, instead of compressed air, a rotating wheel 316 is used to propel the abrasive grit against the hull surface, and an abrasive supply system for automatic recovery of the grit used is disclosed.
