Advanced Functional Maintenance Management for Mining Excavator

The concept of advanced maintenance management technique in the field of heavy duty mining machinery/equipment has recently been developed in India. This maintenance concept has the significance of creating a support system for mining equipment functioning. Functional maintenance is one of the most frequently used methods in maintenance management for mining industries. Management of a custom built maintenance system is the need of the day because of large capital, productivity and risk involved with the mining machinery (excavators) in a high capital intensive industrial scenario with acute sensitivity in the performance of such machines. This paper tries to present some aspects related to the systemic approach of the functional maintenance model, starting from technical elements of the maintenance process to economical perspective of the maintenance process i.e. maintenance-related expenditure or, in other words, to develop an effective maintenance methodologies of mining machinery such that the different maintenance costs are minimized and technical constraints are efficiently monitored and maintained. Based on the above factors maintenance plans are prepared, formulated and implemented. The final part of the paper presents a systemic method of representation of the model, taking into account the two mentioned aspects.
