Zusammenfassung:The method allows higher speed in assembling a wind turbine a tower (1), a nacelle (2) and a rotor, the tower (1) comprising at least two stackable annular sections (3, 4, 5, 6) made of concrete, the method comprising the steps of a) stacking the annular sections (3, 4, 5, 6) by using lifting and positioning means; b) stacking the nacelle (2) onto the upper annular section (6) by using lifting and positioning means; and c) connecting the annular sections (3, 4, 5, 6) to each other, as well as the upper annular section (6) to the nacelle (2), through main connecting means adapted to withstand loads induced by the wind turbine rotor, wherein the step c) is performed after stacking the nacelle (2) onto the upper annular section (6).
