Method of handling wind turbine blades and device for mounting wind turbine blades, in particular mounting blades on a wind turbine

摘要

A method for handling a wind turbine blade and mounting said blade on a wind turbine hub located at a nacelle at the top of a wind turbine tower is described. The wind turbine blade is lifted with a lifting system for handling wind turbine blades, in doing so said wind turbine blade is oriented in a substantially horizontal position. The wind turbine blade is fixed in the substantially horizontal position to the wind turbine hub. The lifting device is released from the blade using a remote control unit. The lifting device is further on removed from the blade.

主权项

1. A wind turbine blade lifting device, comprising:
a lifting frame having at least one seat arranged to provide lateral support to an upwardly-positioned trailing edge of a wind turbine blade disposed in the lifting frame; at least one flexible belt wound affixed to the lifting frame around a downwardly-positioned leading edge of the blade to support an entire weight of the blade; and a remotely controllable release mechanism connected between the at least one flexible belt and the lifting frame to release said belt from supporting the weight of the blade and to permit the lifting device to be removably raised from the blade.
