发明名称 BLADE LIFTING SYSTEM WITH SALOON DOORS
摘要 A system for lifting a blade of a wind turbine is proposed. The system includes a yoke device lifted by a crane, an upper bracket device and a lower bracket device that are mounted to the yoke device for holding the blade. The upper bracket device engages a first section of the blade and the lower bracket device engages a second section of the blade. The lower bracket device is movably mounted to the yoke device in such a way that the blade is insertable into the system in an open position of the lower bracket device. The lower bracket device is movably mounted to the yoke device in such a way that the blade is spatially fixed by both the upper bracket device and the lower bracket device in a closed position of the lower bracket device.
