Mobile test stand validation for measuring friction coefficient of carrying rope with friction lining

The article presents the problem of friction between the rope and the friction liner of a mining hoist very important for the safety of human transport. The friction linings approved for use in the Polish mining industry and their basic mechanical properties are presented. Laboratory and operational methods of friction feedback are described. This article presents an innovative mobile research stand developed at the Department of Mining Mechanization and Robotisation. The mobile test stand validation was presented.
