Kalmar will support the planning, engineering and execution of extending the heightening as well as commissioning the project, which is expected to be completed at the end of next year.
The height of the three cranes, which were operational since 2006, will be increased to seven metres by inserting leg extensions below the portal beams and incorporating bolted flange junctions in the existing welded crane leg construction.
The cranes are mounted using specialised jacking towers and hydraulic jacks during the course of the operation. Structural reinforcements in crane travel and trolley travel direction will also be a part of the project.
Kalmar Crane Upgrades Projects manager Erik Kocken said: "The professional planning and execution we provide in this kind of heightening project keeps disruption to the terminal’s operational efficiency to a minimum.
"Our relationship with DP World is a long and fruitful one, and I’m extremely pleased that they have once again chosen Kalmar to support them in their continued drive to improve the efficiency of their container-handling operations."
