CASE STUDIES OF AUTOMATED ROPE CONDITION MONITORING SYSTEMS

Summery

The concept of automated condition monitoring of steel wire ropes instead of conventional non-destructive testing resonates with industrial companies but rarely comes to the practical implementation of these systems due to a number of challenges of both technical and organizational nature. In this context, a detailed presentation of experience in the implementation of the Intros-Auto automated condition monitoring system (ACMS) for wire ropes at mining and drilling facilities. This could be of interest for other companies. In contrast to conventional rope testing instruments, the ACMS can be customized for each individual site, integrated with other measuring equipment of the hoisting machine, and provides commonly used criteria for rope condition and discard. Integration of rope condition monitoring into site’s information system is particular important, so far it provides essential information for asset management and planning operations.  Another important point is the reliability of the reported rope condition data. It depends on several factors: probability of wire break detection, probability of false-signal detection, accuracy of LMA estimation. Particularly important is the accuracy for estimating the number of broken wires in a cluster.
