Method of lifting a wind turbine blade

Abstract

Method of lifting a wind turbine blade, where said method comprises the step of providing a wind turbine blade, providing a blade yoke and connecting the blade yoke to the blade, providing an elongated element connected to the blade adjacent to the suction or pressure surface, the elongated element: being arranged along at least 50% of the outer ⅓ of the blade, being arranged along the longitudinal axis of the blade, and the elongated element being arranged to reduce the coefficient of lift of the blade by more than 20%, and lifting the blade via the blade yoke. In this way, a simple way of mitigating the lift of the blade during lifting operations can be provided which increases the safety of the procedure and allows smaller lifting yokes to be used in the same winds, or the same lifting yokes to be used in higher winds.
