Liebherr offshore crane for Hochtief
20 June 2013
Components for Liebherr’s new heavy lift CAL 45000-1200 Litronic offshore crane have been transported from Liebherr MCCtec Rostock, Germany, to the Crist shipyard in Gdynia, Poland.
The components, which weigh up to 420 tonnes each, were loaded onto two ships in the port of Rostock in June. Once they arrived in Gdynia, the cranes are being installed on the Vidar, a vessel belonging to Hochtief Solutions.
The CAL 45000-1200 Litronic has a lifting capacity of 1,200 tonnes at a radius of 27.5 metres. The crane rotates 360 degrees around one of the four jack-up legs of the vessel. This is where is gets its CAL name (crane around the leg).
Boom length of the crane is 108 m and its dead weight is 1,500 tonnes. It is a twin-boom design, so the two booms run parallel to each other at a distance of 14 m. Lifting height is 120 m above deck. The crane's slewing ring has an outer diameter of 13 m. The crane is designed to have a relatively small obstruction area of only 12 m.
Once fully assembled, the crane will be used for the installation of offshore wind power stations.
