Tsuji Deck Crane Boom Repair

Alatas Middle East completed a comprehensive Tsuji deck crane boom repair and overhaul type 4525.

The damages caused to the crane boom foot section to be newly built and which was changed-out with the damaged unit. Heavy corrosion caused excessive wear on the boom top structure connecting the boom’s main section with the boom head which accommodated all luffing and hoisting wire sheaves. 

For the boom top section repair, it was necessary to separate the boom head from the main section and to rejoin after replacing large areas of corroded 6mm sheets.

Due to the load-carrying structure, it was necessary to work closely with the certifying authority GL.
