Complete overhaul of cargo cranes

Region: Hong Kong
Alatas Service: Field Service & Parts Supply

During Alatas pre-docking inspection it was found that the hoisting winch frame and boom hinges of both cargo cranes were fully corroded and needed to be renewed.

Several corroded areas on the boom were found which required steel repair, nearly underneath rope guides and the boom head. The hydraulic system also needed a complete overhaul.

Alatas Hong Kong Ltd provided a Field Service Engineer and Crane Structural Engineer from Alatas Crane Designs GMBH during the dry-docking.

In close cooperation with the vessel technical management and the yard, the winches, booms and luffing cylinders and hydraulic pumps and motors were removed.

The winches were fully overhauled in the yard and repair procedures for all structural repairs were produced on-site and the repair followed. All hydraulic pumps and motors were repaired in-house by Alatas Hong Kong.
