A crane arrangement for a wind turbine generator, which is disposed at least partly inside a hub of a wind turbine generator, is provided. In order to provide a more flexible transporting means for handling equipment, that is components, spare parts, tools or the like, within the rotor head of a wind turbine generator, which transporting means allows for an easier and time- and work-saving operation, a crane arrangement is proposed comprising a supporting frame, a crane member, and a coupling member for movably coupling said crane member to said supporting frame so as to allow a movement of the crane member relative to the supporting frame. This is especially advantageous in cases where no direct access from the nacelle to the interior of the hub is possible, so that a crane within a wind turbine nacelle is not applicable for transport use within the rotor head. |
