초록 ▼

A method of mounting rotor blades to a rotor hub which is connected to a pod of a wind power installation, includes the following steps: rotating the rotor hub into a predetermined first position, fitting a rotor blade, rotating the rotor hub by means of the rotor blade into a predetermined second position, and mounting a second rotor blade, wherein the rotation of the rotor hub is effected in the direction of the effect of gravitational force of the first rotor blade which is already mounted. In that way when mounting rotor blades to wind power installations involving a relatively high hub height it is also possible to use a crane which is also sufficient for mounting the rotor hub itself or the pod. Also shown is a rotor blade to be mounted for a wind power installation, the rotor blade having at least one through hole.

대표청구항 ▼

The invention claimed is: 1. A method of mounting rotor blades to a rotor hub of a wind power installation, wherein the rotor hub is connected to a pod, comprising: rotating the rotor hub into a predetermined first position; fitting a first rotor blade; rotating the rotor hub by means of the first rotor blade into a predetermined second position; rotating the pod 180 degrees from a first position with respect to a pylon to a second position with respect to the pylon before the second rotor blade is fitted; mounting a second rotor blade, characterized in that the rotation of the rotor hub is effected in the direction of the effect of gravitational force of the first rotor blade. 2. The method according to claim 1 characterized in that a crane engages a rotor blade and assists with the rotary movement of the hub. 3. The method according to claim 2 characterized in that the crane engages a through hole in the rotor blade. 4. The method according to claim 1 characterized in that the rotor hub is rotated by means of the second rotor blade into a further predetermined position, the pod is again rotated through 180 degrees from the second position with respect to the pylon to the first position with respect to the pylon, and a third rotor blade is fitted.
