Equipment maintenance performance indices allow quarries to understand the value
created by maintenance, in a bid to re- evaluate and revise their maintenance policies and techniques,
to justify investment in new trends and techniques for maintenance management. This research
has attempted to evaluate and compare three maintenance performance indices I1, I2 and I3
(maintenance index; downtime index; and production index respectively) for the studied quarries
computed from their records of operational output and maintenance costs for the period reviewed.
The index I1 was determined to be between 10 and 20% as against the global standard of less than
6%; index I2 ranged between 19 and 25% as against the industry norm of less than 1% and index
I3 averaged 28.5%, while global standard is between 12 and 14%. These indices are not in
conformity with the global best standard, this performance is worrisome and has a negative impact
on the viability of the quarry business. It becomes imperative therefore that their maintenance
policies be revised and their maintenance strategies overhauled to enhance higher performance
that can impact positively on the overall corporate goal of the quarries.
Keywords: Quarry equipment, maintenance, evaluation and performance indices.
