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.
Claims7
A lifting beam for lifting a rotor blade of a wind power installation, the lifting beam comprising:
- a crane fixing means for fixing the lifting beam to a crane;
- three blade fixing means for fixing the lifting beam to the rotor blade, each blade fixing means having a respective carrier loop for releasable fixing to the rotor blade;
- a longitudinal pivoting means for pivoting the rotor blade carried by the lifting beam about a longitudinal axis of the rotor blade, wherein the longitudinal pivoting means has a linear actuator that includes a hydraulic cylinder for raising and lowering at least a portion of the blade fixing means, wherein the linear actuator is arranged between one of the carrier loops of one of the blade fixing means and the lower carrier frame portion;
- and
- a transverse pivoting means for pivoting the rotor blade carried by the lifting beam about a transverse axis that is transverse relative to the longitudinal axis.
