METHOD FOR ACCESSING THE OUTER SURFACE OF WIND TURBINE TOWERS AND DEVICE FOR USE WITH THIS METHOD

摘要

Method for accessing the outer surface of wind turbine towers comprising the following steps: attaching an external peripheral rail on the outer surface of the tower; making an orifice above said rail; arranging a working platform on the base of the tower; inserting a cable reel in the orifice; raising the platform by driving the cable reel until it is near the peripheral rail; arranging means for suspension and horizontal displacement on the horizontal rail; connecting the platform to said means for suspension and horizontal displacement and displacing the platform as needed.
