Weldex purchased the first unit of LR11350-P1800

Weldex has show interest and bought the first unit of the LR11350-P1800. The crane was immediately shipped from the factory to Eemshaven, the Netherlands for a wind power job. The job was a joint effort together with Mammoet, which was also one of the major Dutch competitors.

The scope was to lift the 18 meters by 7 meters machine housing of a 6MW class wind turbine belonging to Repower (renamed to Senvion). The 340 tonnes load has to be raised onto a tower of height 110 meters. The gross weight of the load including hook and tackle was 378 tonnes. A total of two 6MW from Repower was installed by the LR11350-P1800 in Eemshaven, which both served as test facilities. Plans are for 48 turbines of the similar type to be installed from 2013 onwards in the North Sea East offshore wind park, off the island of Heligoland.
