Abstract
The invention provides a turning stand for turning a rotor hub from a position having its prospective axis of rotation oriented vertically to a position having its prospective axis of rotation oriented inclined or transversally to a vertical orientation. The turning stand comprises a base frame, a curved support frame and a second attachment structure for attachment of a lifting device to the rotor hub. The base frame has a support plane and a first attachment structure for attachment to a rotor shaft link of a rotor hub, the support plane and the first attachment structure being arranged on opposite sides of the base frame. The curved support frame comprises a curved frame section and a straight frame section having a curved support surface section and a straight support surface section, respectively. The straight frame section with the straight support surface section is arranged laterally of the prospective axis of rotation of the rotor hub and the straight support surface section is angled to the prospective axis of rotation of the rotor hub by less than 15°. The curved frame section is connected between the base frame and the straight frame section such that the curved support…
