A LIFTING ASSEMBLY FOR ELEVATING COMPONENTS TO A WIND TURBINE AND A METHOD FOR USING THE LIFTING ASSEMBLY

摘要

The present invention relates to a lifting assembly (1) for elevating components (3) to a wind turbine (5). The lifting assembly comprises a plurality of tower segments (13) adapted to be arranged on top of each other to form an elongated tower (9), and a lifting device (2) including a support frame (11) for supporting the tower, a securing assembly (32) for securing the tower to the wind turbine, and a crane (21) having a base part (23) and a jib (24) rotatably connected to the base part. The lifting device (2) comprises a platform (7) arranged vertically moveable between a lower and an upper position.The platform has a first storage area (19) for supporting components with a weight of more than 10 ton.The crane (21) is mounted on the platform (7) and is configured to move the components between the platform and the wind turbine when the platform is in the upper position. The platform is provided with an opening adapted to receive the tower segments.The crane and the first storage areaare arranged on opposite sides of the opening, andone of the tower segmentsis a top segment (26) having an upper part (27) provided with a second storage area for supporting components with a weight of more than 10 ton.The invention also relates to a method for using the lifting assembly for replacing an old component of a wind turbine with a new component.
