The article presents and compares the results of experiments and numerical calculations of fatigue life of the cast lock of scraper conveyor used in the mining industry. The scope of research included determination of the fatigue life characteristics of ADI based on LCF and MLCF tests and fatigue life studies carried out directly on the casting of the lock. The state of stress in casting caused by the effect of forces applied in the test equipment was determined by the finite element method. The obtained results were used in calculation of the fatigue life of the lock applying selected hypotheses of the multiaxial fatigue. The results of calculations were compared with the results of experiments, evaluating at the same time also the validity of the adopted hypotheses.
