BLADE GRIPPING DEVICE WITH RECTANGULAR CARRYING STRUCTURE

摘要

A blade gripping device for gripping a rotor blade of a wind turbine is provided. The device comprises a first frame which is essentially horizontally aligned in a designated operating position and a second frame which is essentially horizontally aligned in the designated operating position and a blade gripping assembly with a number of blade gripping tools. Thereby, the first frame and the second frame are connected to each other via a swivel or other similar type connection, the connection realized to permit a yawing movement of the second frame relative to the first frame. The first frame comprises a rectangular carrying structure with at least four connectors for connection to a lifting device, which connectors are positioned essentially at the corners of the rectangular structure. Further, the invention concerns a method of operating a blade gripping device for gripping a rotor blade of a wind turbine.
