A more efficient and simple wind turbine generator with a lifting device and method of using the lifting device is disclosed. A wind turbine generator comprises a tower, a nacelle supported by the tower, the nacelle comprising a foundation supporting components of the nacelle, a yawing system comprising a yaw bearing enabling rotation of the nacelle relative to the tower, a lifting device internally in the wind turbine generator and capable of moving an item, a support supporting the lifting device, and wherein the lifting device is moveable in a horizontal direction from a first position to a second position, and at least one of the positions is, in a vertical direction, between a lowermost level of the foundation, such as just above the yaw bearing, and an uppermost level of the tower, such as just below the yaw bearing.
