Abstract
A method of mounting a wind turbine rotor blade to a partial assembly is provided, the partial assembly including a number of rotor blades mounted to a hub which in turn is connected to a rotor shaft of a wind turbine, the method including the steps of A) effecting a rotation of the rotor shaft to turn the partial assembly from its starting position through an initial arc (β0); B1) allowing the partial assembly to swing through a free swing arc in the opposite direction; B2) effecting a rotation of the rotor shaft to extend the free swing arc (α) by a further arc (β); and C) repeating steps B1 and B2 until the partial assembly has reached a final position at an angular displacement of 120° to the initial position.
