A method is disclosed for establishing access to mounting and demounting of main shafts (14), gearbox (16), generator and other main parts located in the nacelle (2) of a wind turbine (4), where the cabriolet (6) remains localized on the nacelle (2), and means in form of guide transfer mechanisms (18, 18', 22, 22') for mounting inside the nacelle (2) to perform the method according to the invention. The basic idea is, that the cabriolet (6) is lifted upon rolls or roll sets (54) which forms the guide transfer mechanisms upward facing support surfaces, and that the cabriolet is stabilized by displaceable counter holds (62) which is displaced and locked in position above the downwards positioned mounting flange (58), upon which the cabriolet (6) can be displaced on the rollers or roll sets (54) to a partly cantilevered position over the rear end (28) of the nacelle (2). By the method according to the invention service on larger wind turbines can be performed, without using mobile cranes, which saves resources. |
