Safe use of mine winding rope, volume 2: recommendations for changes in rope safety factors.

Abstract

The steering committee on factors of safety of winder ropes has appointed a working group to draw up a set of proposals for changing the regulations governing the required rope strength in the Minerals Act. Certain research projects have been conducted in order to substantiate the recommendations. The results of these projects have shown that a new set of regulations could be recommended for drum winder ropes even though detailed knowledge on rope deterioration was still lacking. The regulations should effectively limit the dynamic load range regulations, however, and to make provision for dynamic winder behaviour in a code of practice.
