Abstract

Method for lifting a wind turbine component The present invention relates to a method for lifting a wind turbine component, such as a rotor blade (2), gearbox or a rotor, with a lifting yoke (10) comprising a first structural body (20) comprising a crane hook attachment point (21), a first connection point (22) and a second connection point (23), a second structural body (30) comprising a third connection point (31) and a fourth connection point (32). First and second tensional elements (24, 25) such as slings or wires, are connected to the connection points, the length of the second tensional element being variable. An inertial measurement unit (40) determines the angle of the second structural body to the horizontal and the angle of the second tensional element is determined by an angle sensor. The distance (D) from the fourth connection point to the intersection between an axis (V) extending vertically through the center of gravity of the wind turbine component and the lifting plane is determined and provided to a crane operator. The invention also concerns a corresponding yoke.
