Definitions

  • the present invention relates to a lifting frame for lifting and installing the blades of wind turbines of the type comprising a frame having a first and a second end adapted to be connected to a wind turbine blade, as well as a winch of a crane with crane jib for carrying the weight of the blade, wherein the frame is adapted to lift maintain a therein arranged wind turbine blade in a substantially horizontal plane, alternatively, the lifting frame being adapted to lift and maintain in this positioned wind turbine blade in approximately any conceivable orientation different from the one in the substantially horizontal plane and position, hanging in the crane main wire, and wherein the crane comprises at least two secondary independent winch systems with secondary wires, and wherein the crane jib comprises a number of cooperating secondary pulleys, located at the towards the main wire adjacent side of the crane jib, alternatively at crane jib sides.

  • the known lifting system for wind turbines comprises that the guide cable/guide wires is connected with winches located on the lifting device, resulting in an increase of weight of the lifting device, and further a control problem, as it will be necessary to be able to remote control the winches, since the wind turbine lifting system is not provided staffed.
  • a further an more pronounced problem is, that the guide cable only in a certain extent secures the directional stability during lifting and handling of a wind turbine blade in a substantially horizontal plane, since only the weight of the frame in combination with the weight of the wind turbine blade contributes to secure the wind turbine blade in the frame against wind action during installation of the blade on the turbine hub.
  • Some kind of control is sought established by providing the winch on the frame of the lifting device with a slack block which establishes a counter hold relative to the winches displacement of the control cable.

  • the therewith increased horizontally oriented force application of the frame leads to a substantially increased stability of the wind turbine blade, and thus a higher degree of safety during handling and in- stalling wind turbine blades arranged in the lifting frame according to the invention. Since the prior art control devices does not offer the possibility of providing a double triangular control with the possibility of generating a downwards oriented influenced force on the lifting frame, the use of the lifting frame according to the invention will result in a significant increased stability of the wind turbine blade during installation, in larger wind appliance, where the prior art control devices are not sufficient.
