Abstract

See full text

A method for establishing access for mounting and dismounting of main shafts, gearbox, generator and other main parts located in the nacelle of a wind turbine, where the cabriolet remains localized on the nacelle, and guide transfer mechanisms are provided for mounting inside the nacelle. The basic idea is that the cabriolet is lifted upon rolls or roll sets which form the guide transfer mechanisms upward facing support surfaces, and that the cabriolet is stabilized by displaceable counter holds which are displaced and locked in position above the downwards positioned mounting flange, upon which the cabriolet can be displaced on the rollers or roll sets to a partly cantilevered position over the rear end of the nacelle. By the method, service on larger wind turbines can be performed without using mobile cranes, which saves resources.
