The present invention relates to a wind turbine enabling a cost effective and easy a The present invention relates to a wind turbine enabling a cost effective and easy attachement/replacement of rotor blades and to a method of attaching a rotor blade to a hub of a wind turbine. The wind turbine in accordance with the invention comprises a tower (102) resting on a base (104), at least one rotor blade (112) having a blade connector portion, a nacelle (100) housing a shaft to which a hub (118) is attached, the nacelle (100) being mounted atop the tower (102). Said hub (118) of the wind turbine comprises a plurality of hub connection flanges (131, 164), each hub connection flange (131, 164) being adapted to be detachably connected to a blade connector portion of a rotor blade (112). The wind turbine further comprises a blade pulley system (157) including at least one pulley and being detachably connected to the blade connector portion of a rotor blade (112), and a truss system (135), said truss system comprising a pulley beam (146) including at least one pulley (148a, 148b) and two mounting beams (141, 143), each mounting beam being detachably connected to a hub connection flange, thereby positioning the pulley beam (146) above a further hub connection flange. |
