Method and attachment for handling a rotor hub of a wind turbine

摘要

The method involves arranging a rotor hub (11) or a rotor (10) with a mounting side at a tower of a wind energy system. The rotor hub or the rotor is held or lifted by a lifting device i.e. crane. The rotor hub in a lifted condition or the rotor is tilted from an original lifted position around a tilting angle by a tilting device (15), which is arranged at the rotor hub or at rotor blade root of a rotor blade (12) of the rotor. The tilting device is activated or switched-on for performing a tilting process. An independent claim is also included for a device for handling a rotor hub or rotor of a wind energy installation during constructing the wind energy installation or mounting /demounting the rotor at the installation.
