Replacement of 4 x ALATAS Supplied Crane Slewing Bearings on Mitsubishi Deck Cranes

ALATAS Singapore recently carried out the replacement of 4 sets of crane slewing bearings at Anchorage. The bearings were supplied by ALATAS in a very short time of approximately 3½ months and installed at Singapore Anchorage, using a floating crane. Proper planning and ALATAS experienced personnel on site ensured that the job was carried out in the shortest possible time, the expensive floating crane was alongside for only 2 days.
