AATS Continuous Rope Condition Monitoring
Technical Meeting The Non-destructive Testing of Rope – Krakow 1995
Reaching deeper ore bodies in an economically viable fashion is one of the problems faced by the South African gold industry. One of the major stumbling blocks in very deep single lift shafts is the problem of rope load exceeding acceptable levels. Total rope load is comprised of rope weight, cage weight, payload weight, strain due to acceleration, and strain due to rope dynamics. In a study examining the factors influencing very deep hoisting, a number of ways to address the rope load issue were identified, each targeting a specific component of total rope load. These solutions included lighter (e.g. aluminum) conveyances, "stronger" ropes (better strength to weight ratio), and better winder control systems/strategies (addressing strain due to rope dynamics).
