1. A method of servicing or installing a component of a wind turbine using a crane, the wind turbine including a nacelle and a rotor hub coupled to the nacelle and rotatable about a rotor axis, the method comprising:
rotating the rotor hub about the rotor axis to a first rotational position;
lifting the crane to the rotor hub while the rotor hub is positioned at the first rotational position;
wherein the crane includes a crane base, the method comprising mounting the crane base to a mounting portion of the rotor hub while the rotor hub is positioned at the first rotational position;
rotating the rotor hub together with the crane from the first rotational position to a second rotational position; and
after rotating the rotor hub together with the crane from the first rotational position to the second rotational position, connecting at least one load supporting arm from the crane base into the nacelle through an access in a roof of the nacelle to a bedplate of the nacelle.
