Kalmar, part of Cargotec, has completed the relocation of an 850 ton Kalmar ship-to-shore (STS) crane for its customer the Port of Helsingborg, Sweden (Helsingborgs Hamn AB). The order was signed in September 2013 and the work was completed within a two week time frame during November.
The complex project, which was handled by Kalmar’s specialist Crane Services Competence Centre for North Europe located in Rotterdam, required the STS crane to be moved by barge from the customers Scania Terminal Quay 705 to the West Harbour, Helsingborg Quay 906. The scope of works required detailed engineering calculations to ensure the crane remained stable throughout its transportation.
Bengt Niklasson, Manager Port Infrastructure at the Port of Helsingborg, was full of praise for the Kalmar team. He 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 ton structure.
“The crane also required structural modifications to eliminate a 400mm 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. What particularly impressed me was that the actual lifting, moving and relocating, including the sea transportation, was completed within one day. A very impressive achievement”, he concluded.
Vice President, Kalmar Crane Services, Gert Jan Doornewaard said, “Crane relocation offers an innovative solution to ports who need to maximise their container handling capacity relatively quickly. Kalmar has developed a range of highly advanced technical solutions to facilitate this. It means we can continue to offer our customers a level of service that optimises the productivity of their operations. Our dedicated Crane Services project teams around the globe carry out these projects for all brands of equipment.”
