Condition based maintenance management system for improvement in key performance indicators of mining haul trucks-a case study

Abstract

Condition based maintenance (CBM) is a preventive maintenance management concept that considers the repair or replacement decision based on the normal and abnormal condition of equipment. It requires that any variation in the condition or performance of the equipment stipulates the specific reason for executing the maintenance. Whereas preventive maintenance is maintenance performed on an item to prevent failure. Condition maintenance helps to detect the hidden faults even when mining equipment is in operation and therefore helps reduce the major production losses. Performance of the equipment also gets better as overall equipment efficiency improves due to fewer stoppages and finally the improved utilization of the equipment results into better equipment productivity. In manual systems, it is difficult to quickly detect, diagnose and troubleshoot the faults. CBM system therefore supports to reduce the workshop inventory, breakdown and maintenance time and performs a major role to improve the equipment performance and productivity.
