Vessels often have cranes on deck and shipyards also have cranes at their piers. So that the cranes can spin without problems on the axis of their own, a slewing ring gear is installed between column and crane house. The slewing ring landing faces on columns and crane houses are machined by us in the highest precision class. The life time of a slewing ring gear is fundamentally influenced about the flatness of the landing faces.
T&D is a specialist in machining of crane slewing ring landing faces.
