Abstract
A method for mounting rotor blades of a wind turbine is provided. The wind turbine has a rotor hub with three rotor blade ports. A rotor blade is to be mounted to each of the three rotor blade ports. A mounting arm is fastened to a first rotor blade port. The mounting arm has a first section and a second section, which are coupled with each other via a hinge, so that the angle between the first and second sections can be varied. The hub is turned until the first rotor blade port is in a 90° position. A first end of the first section of the mounting arm is fastened to the first rotor blade port of the rotor hub. The rotor hub is turned with the help of the mounting arm, until the second rotor blade port is in a 270° position. The angle between the first and second sections of the mounting arm is varied while turning the rotor hub. A first rotor blade is lifted, so that the first rotor blade is horizontally mounted to the second rotor blade port of the rotor hub.
