The paper presents results of tests and assessment of the WPS-Ec inserts, which were carried out in a Division of Statutory Tests in the KOMAG Mining Mechanization Centre. The inserts are used for force measurements in ropes in the mining shaft hoists and due to this they are installed in the suspensions of conveyances and shaft hoist ropes. The use of these inserts means the use of additional safety measure during the ropes’ operation in the shaft hoists, which will have wide range of possibilities to be used. This measure is a practical tool, not commonly used so far, which can be used by the personnel responsible for the safety of mining shaft hoists’ operations.
