Claim Text:
1. A method for assembling/disassembling a rotor to/from a wind powerplant, where a rotor hub, or the rotor, is mounted at one assembly side to a tower of the wind powerplant, the method comprising the steps of: providing a tilting mechanism that is affixed to at least one of the rotor hub and rotor blade roots of the rotor, wherein the rotor hub and the rotor each define a respective center of gravity, wherein the tilting mechanism includes an actuator and an engagement point, and wherein the actuator is at least one of a telescopic cylinder, a cable winch, and a control cable to shorten and lengthen a cable; raising the rotor hub or the rotor and holding the rotor hub or the rotor with a hoisting device with a hoisting means that engages the engagement point of the tilting mechanism, wherein the engagement point of the tilting mechanism is a force application site for the hoisting means connected thereto; tilting the rotor hub in the raised state with the tilting mechanism, out of an initially raised position by a predetermined angle of tilt or tilting the rotor from the initial, raised position through the predetermined angle of tilt with the tilting mechanism, wherein in either tilting step, the tilting mechanism is directly connected to the hoisting device and a distance between the engagement point and either the rotor hub center of gravity or the rotor center of gravity is changed, wherein the engagement point is stationary during the tilting of the rotor hub; and providing guide cables that do not tilt the rotor or the rotor hub, but further orient the rotor or the rotor hub.
