Proactive maintenance is a maintenance strategy for stabilizing the reliability of machines or equipment. Its central theme involves directing corrective actions aimed at failure root causes, not active failure symptoms, faults, or machine wear conditions.
A typical proactive maintenance regimen involves three steps:
- (1) setting a quantifiable target or standard relating to a root cause of concern (e.g., a target fluid cleanliness level for a lubricant),
- (2) implementing a maintenance program to control the root cause property to within the target level (e.g., routine exclusion or removal of contaminants),
- and (3) routine monitoring of the root cause property using a measurement technique (e.g., particle counting) to verify the current level is within the target.
Famous quotes containing the word maintenance:
“However patriarchal the world, at home the child knows that his mother is the source of all power. The hand that rocks the cradle rules his world. . . . The son never forgets that he owes his life to his mother, not just the creation of it but the maintenance of it, and that he owes her a debt he cannot conceivably repay, but which she may call in at any time.”
—Frank Pittman (20th century)
