<p>The crane has a load hook (20) fastened indirectly/directly at a crane hoist rope (50). A frame is suspended at the load hook for receiving a special load i.e. rotor blade (101), of a wind turbine (100). Control elements e.g. control ropes (40), of the frame suspended at the load hook are guided along a guide rope area (50a) of the rope. The guide rope area is formed by returning the hoist rope by a pulley block (23) via a guide roller (14) in a direction as a boom longitudinal axis to a lower anchorage point at the crane. The guide roller is mounted at a variable height at a crane boom. The control elements are spindles and/or cylinders and/or telescopic seaweeds and/or kink steering wheels.</p> |
