Method for in situ installation of rotor blades on the rotor hub of a wind power plant, balancing weights, use of such weights and the wind power plant

摘要

One aspect of the present invention concerns a process for mounting rotor blades to a rotor hub of a wind power installation in situ. In order to avoid high torques in the mechanical train of the wind power installation in the operation of mounting the rotor blades, a process according to one aspect of the invention includes the following steps: mounting a weight to at least one flange of the rotor hub; mounting the rotor blade in the installation situation; rotating the rotor hub into a predeterminable position; and exchanging the weight arranged on the flange of the rotor hub for a rotor blade by removing the weight and then mounting the rotor blade to the rotor hub.
