| 摘要 |
The invention relates to a load-handling apparatus (1) for lifting rotor blades (14) into a mounting position, having a crane (20) with a crane jib (26), a crane hook (22) and with fastening means (25, 24) for fastening a rotor blade (14) in a releasable manner on the crane hook (22), wherein a supporting device (46, 48a, 48b, 50a, 50b; 60, 64) is fastened in an upper region of the crane jib (26), this supporting device having a supporting surface (72) which projects into the vertical movement plane of the rotor blade (14) such that the rotor blade (14) or the fastening means (25, 24) come into abutment against the same during the lifting operation, wherein the supporting device (46, 48a, 48b, 50a, 50b; 60, 64) is of rigid design, wherein the supporting surface (72) is formed such that the rotor blade (14) is secured against rotation about a vertical axis. The invention also relates to a method for mounting rotor blades (14) on the rotor hub (13) of a wind turbine (10). |
