Tandem Telescopic Lift at Cuxhaven

Mammoet has erected a 600-ton dock crane at the site of a new facility for the production of components for offshore wind farms at the Port of Cuxhaven in Germany.
The gantry crane has two main girders with a length of 236 feet and weight of 250 metric tons each, and a 155-ton trolley.
Because the site was too small for boom cranes, Mammoet used two LTM 11200s, or telescopic cranes, to erect the dock crane in a tandem lift. By using the two cranes in different configurations, operators were able to manage the geometrical properties of the loads and their lifting points, according to a Mammoet statement.
The Port of Cuxhaven is located on the North Sea, which already has more than 1.5 gigawatts of installed offshore wind capacity.
