Lifting Assembly For Elevating Components To A Wind Turbine And A Method For Using The Lifting Assembly

Abstract

A lifting assembly for elevating components to a wind turbine. The lifting assembly comprises a plurality of tower segments adapted to be arranged on top of each other to form an elongated tower, and a lifting device including a support frame for supporting the tower, a securing assembly for securing the tower to the wind turbine, and a crane having a base part and a jib rotatably connected to the base part. The lifting device comprises a platform arranged vertically moveable between a lower and an upper position. The platform has a first storage area for supporting components with a weight of more than 10 tons. The crane is mounted on the platform 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 area are arranged on opposite sides of the opening, and one of the tower segments is a top segment having an upper part provided with a second storage area for supporting components with a weight of more than 10 tons. 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.
