The safety lifting system with safety features is used especially for a castling ladle crane. The ropes form two kinematic chains with upper and lower rollers and and a double armed compensation lever. The swinging movements of the transverse member in the travelling direction of the crane have no effect on the compensation level and the stops for limiting the displacement of the compensation level when one rope breaks can be arranged very closely to the ends of the compensation lever. Each rope held on the rope drum (1) is passed in succession over two pulley systems which are located on different sides of the vertical longitudinal plane of the transverse member (4). |
