  • the restraining means 444 is disengaged and stays 600A, 600C are removed.
  • the elongate mast 300 is then lowered from the second raised position 360 to the first lowered position 350 by the winch acting through the lifting member 390.
  • the support frame 700 is re-attached during this stage.
  • the wind turbine 200 can be serviced at ground level.
  • the wind turbine 200 is disconnected and the remaining components of the wind turbine disassembled by reversing the above procedures.
  • the wind turbine 200 can be lowered easily and quickly, without the need for heavy machinery, such as a crane.
