Abstract
An apparatus for lifting a wind turbine blade to a rotor hub includes a blade holder configured to receive and support the wind turbine blade. A connection element is configured on the blade holder and is adapted to attach directly to a mounting surface of a wind turbine rotor hub. A lifting equipment attachment is configured on the blade holder to attach to the blade holder to lifting equipment. A first steering mechanism is operably connected between the blade holder and the lifting equipment attachment to control an orientation of the blade held by the blade holder with respect to the lifting equipment attachment.
