摘要： In a blade lifting method and apparatus, the apparatus comprises a lifting bar to be fitted within the hollow, root portion of a wind turbine blade and a lifting connector to be suspended from a crane and passed through a hole in the blade root to engage with the lifting bar. The root end of a wind turbine blade may thereby be supported during lifting by an external lifting means such as a crane. Support pads may be fitted to the lifting bar ends or to the inside of the blade root. These provide a point of engagement between the lifting bar and the internal surface of the blade root. A hole in a blade root may be positioned such that, in a predefined lifting orientation of the blade, the hole lies vertically above the centre of gravity of the blade, or the sectional centre of gravity at the lifting point. The blade root lifting apparatus and method are suitable for both the construction or disassembly of a wind turbine.
