Safety of ropeway installations depends endurance parameters of wire ropes. Computations of rope diameters still utilise a static and deterministic approach to the fatigue endurance and loading. The paper addresses the problem of quantitative assessment of rope safety in the context of cumulative rope wearing, assuming that endurance parameters and forces acting upon ropes are randomly variable. Besides, it is shown that:
numerical values of safety and reliability parameters can be determined in the function of the working conditions of the investigated plant,
a wearing model can be developed,
diagnostics can be related to safety features,
admissible wearing levels can be determined,
safe service life of wire ropes can be prognosticated.
