In a device for cleaning sealing surfaces, especially the sealing groove region of a reactor pressure container pressure container lid which, in a parking position is parked on at least one parking support of a parking device arranged radially inside the downward-pointing sealing surfaces and is centered by guide bolts of the parking device coming radially into engagement with the edge of the lid outside the sealing surfaces, the device having a driven cleaning carriage which can be moved in the direction of the lid circumference and having a cleaning device mechanically cleaning the sealing surfaces, it is provided according to the invention that at least one circular drive rail is arranged on the parking device between the parking supports and the guide bolts, that the cleaning carriage is designed narrower than the radial distance between the parking supports and the guide bolts, moreover has wheels coming into permanent travelling engagement with the drive rail and has at least one tilting safety element which can be brought to guiding engagement with at least one of the sealing grooves and that the mechanical cleaning device is provided with a suction device. The cleaning carriage preferably has a cable drum for a connecting cable and an orbital grinder moved circularly in one plane with low-pressure suction through a fleece-like grinding mat. This device allows an almost complete automatic cleaning of the sealing surfaces, ... Original abstract incomplete.
