An assessment of the susceptibility of Becorit K-255B and Modar R3/Mz friction linings

Abstract

The article presents an assessment of the susceptibility of friction linings from two selected manufacturers. These tests are extremely important when assessing the safety of existing and newly designed shaft lifts and ski cableways. The research was carried out on measuring equipment at the Department of Mining Mechanization and Robotization of the Silesian University of Technology, where this type of research has been conducted for years. A measuring amplifier, road transducers, force transducers and a hydraulic testing machine were used for the tests, thanks to which the pressure was applied to the rope on which the friction lining was applied. The measurements were recorded on a computer, which was a recording and measuring station, after which they were processed, saved in tables and presented to the reader in the form of graphs. The main purpose of these tests was to obtain results giving information about the rope displacement at a specific pressure to the groove of the friction lining. It is also worth mentioning that the factor that has a significant impact on the achieved values of displacements is the time of the test. It is related to the properties of the material of which the friction linings are made that are used as a running track for the ropes.
