  • Wind turbine with yaw bearing lifting device
    Patent number: 9689174
    Abstract: A wind turbine with a tower, a nacelle and a yaw bearing, wherein the yaw bearing is arranged and prepared for rotating the nacelle relative to the tower around a yaw axis is provided. The yaw bearing has a first yaw bearing component which is fixed to the tower, a second yaw bearing component which is fixed to the nacelle, and at least one sliding component which is located between the first yaw bearing component and the second yaw bearing component. The wind turbine is prepared and arranged for housing at least one lifting device for lifting the nacelle relative to the tower such that the sliding component can be removed. Furthermore, a method of lifting the nacelle relative to the tower is provided. Thus, the sliding component may be removed and the removed sliding component may be replaced by a re-placement sliding component.
