Abstract
Official abstract text for this publication.
A method of erecting a wind power installation which has an aerodynamic rotor having rotor blade connections. A lifting beam having a ballast unit is fixed to a crane hook of a crane. A rotor blade is fixed to a second crane hook at an underside of the ballast unit by means of lifting cables. The lifting beam and the rotor blade are lifted by the crane for mounting the rotor blade at one of the rotor blade connections.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of erecting a wind power installation having an aerodynamic rotor blade having a plurality of rotor blade connections, the method comprising: selecting at least one ballast weight so that a predetermined ratio in meters squared per ton between a surface area of the rotor blade and a sum of both the at least one ballast weight and a weight of the rotor blade is equal to or less than 1; fixing the at least one ballast weight to a lifting beam; fixing the lifting beam with the at least one ballast weight to a crane hook of a crane; fixing a rotor blade by lifting cables to a second crane hook at an underside of the at least one ballast weight; and lifting the lifting beam with the at least one ballast weight and the rotor blade by the crane for mounting the rotor blade at one of the plurality of rotor blade connections. 2. The method according to claim 1 , comprising: prior to lifting the beam with the at least one ballast weight and the rotor blade by the crane, fixing a rotor blade root of the rotor blade to a hook of a winch unit; and wherein lifting the rotor blade comprises lifting the rotor blade by the winch unit and the crane.
