ABSTRACT:
An apparatus for assembling a wind turbine includes a crane boom having a main bearing cable coupled to a component for lifting the component during assembly of the wind turbine, and a control mechanism coupled to the crane boom for controlling the orientation of the wind turbine component during the lift. The control mechanism includes a guide member coupled to the crane boom, a movable member coupled to the guide member and configured to be movable relative to the crane boom, a coupling member configured to couple the movable member to the wind turbine component being lifted by the crane boom, and a drive mechanism configured to actively move the movable member relative to the crane boom independent of the movement of the main bearing cable. A method for assembling a wind turbine includes using the coupling member to change the orientation of the component.
