Kalmar relocates 850 tonne STS crane

By Laura Hatton26 November 2013

At the Port of Helsingborg in Sweden Kalmar’s crane service competence centre has relocated a ship to shore (STS) crane weighing 850 tonnes.

It was moved by barge from the Port of Helsingborg’s Scania Terminal Quay 705 to the West Harbour, Helsingborg Quay 906.

Bengt Niklasson, manager port infrastructure at the Port of Helsingborg, said, "Moving an STS crane is not an everyday occurrence and requires a highly specialist solution. The Kalmar team was exceptionally thorough in the preparation and execution of the move. It called for detailed crane stability calculations, structural stiffening of the main frame, ballast engineering and preparation of the barge to handle the 850 tonne structure.

"The crane also required structural modifications to eliminate a 400 mm difference in height between the crane rails at the new location. Additionally, we needed to lower the checkers cabin to provide optimum access and the high voltage cable reel and support were also repositioned on the structure.”

The lifting, moving and relocating, including sea transportation, was completed within one day, a company spokesperson concluded.
