The method extracts ropes from a shaft conveyor in stages when changing ropes or carrying out repairs. After the cage (3) and counterweight have been secured in place, the ropes (1) of the respective run (5) are pulled downwards in stages by a haulage mechanism (7). The mechanism travels upwards while the ropes are secured, being secured to them and then moved downwards as they are released. Thus, the rope between the mechanism and the secured portion is relieved of load, its length being increased with each stage. |
