The present invention relates to erecting tall heavy objects like wind turbine generators, which on remote places like on sea are complicated to assemble. The invention deals with picking a complete wind turbine generator and placing it on its foundation in one operation. Especially the invention concerns a lifting device for a wind turbine generator. A yoke (5) defines the connection between tower (8) of the wind turbine generator (9) and a crane (11) , where the yoke (5) interacts with the tower (8) and in the lifting position lifts a complete wind turbine generator (9) in connection with erection or service. By this arrangement, all the major unbalanced components will be positioned below the hook or attachment point of the wire of the crane. The WTG rotor is balanced and the blade position will have no influence on a stable lift. |
