Abstract: The invention relates to a lifting beam for lifting and handling a rotor blade of a wind energy plant, comprising a fastening means for fastening the lifting beam to a crane, at least one fastening means for fastening the lifting beam to the rotor blade a longitudinal pivoting means for pivoting the rotor blade which is supported by the lifting beam about a longitudinal axis of the rotor blade, and/or a transverse pivoting means for pivoting the rotor blade which is supported by the lifting beam about a transverse axis perpendicular to the longitudinal axis. The invention further relates to a method for mounting rotor blades of a wind energy plant using a lifting beam according to the invention.

Abstract: The invention concerns a rotor hub of a wind power installation comprising a handling apparatus for lifting the rotor hub by means of a crane for mounting the rotor hub to a pod arranged on a wind power installation pylon, wherein the handling apparatus is so adapted that upon being lifted at a fixing portion of the handling apparatus the rotor hub rotates from a perpendicular orientation with a substantially perpendicular hub axis into a horizontal orientation with a substantially horizontal hub axis.

Abstract: A method for mounting a wind turbine rotor blade which has at least one release unit is provided. A hoisting rope is fastened on or in the rotor blade. First ends of at least one auxiliary rope are fastened on or in the release unit in the rotor blade. The rotor blade is lifted up by means of the hoisting rope. The rotor blade is mounted on a rotor of the wind turbine. The release unit is activated so that the first ends of the auxiliary ropes are released. The auxiliary ropes can be removed.

Abstract: A method for forming a tubular body, comprising the following steps: making available a tubular body having a first and a second tube end, filling the tubular body with a liquid, closing the tubular body, and forming the tubular body.
