Lifting system and method for lifting rotor blades of wind turbines

摘要

A lifting system for lifting rotor blades of wind turbines includes a plurality of frame structures each being configured to support a rotor blade. Additionally, the lifting system includes a lifting structure which is attachable to a lifting device, and a number of lifting connectors configured to connect a pack of frame structures to the lifting structure. Furthermore, a method for lifting rotor blades of wind turbines by using a lifting device and a method for installation of rotor blades of wind turbines are provided.
