Present day requirements set on hoisting ropes in mines. In one of the highest hoisting; plants in the Federal Republic of Germany, in the main shaft of the "Consolidation Mine" a useful load of 42 t is conveyed by G ropes arranged in parallel, performing approx . 700 hoists per day each. The service life of these hoisting.; ropes is about two years. During this period they are capable of carrying out around 300 000 hoisting cycles at ~ shaft depth of 1000 m, this means 300 000 lco1 . During their life-time these hoisting: ropes 1dll achieve approx . i\000 operating hours.
