An assessment of rope durability in mining shaft hoists

Abstract

The article presents the issues of the durability of lifting ropes and balance ropes operated in selected shafts of deep mines. The basic causes of hoisting ropes wear are described, the methods of steel ropes wear evaluation are given, as well as the hoisting ropes durability evaluation criteria. The authors also present selected results from the extension of hoisting ropes. The article ends with some conclusions resulting from the research. The article has also been provided with photos showing the measuring equipment used to assess the durability of steel and steel-rubber ropes. The article presents the criteria for assessing the durability of lifting ropes.
