Which maintenance strategy uses real-time sensor data to predict when equipment failure is likely to occur?
Answer: Predictive maintenance
Predictive maintenance uses condition monitoring and sensor data to forecast failures before they occur, reducing unplanned downtime.
What is the primary goal of a Total Productive Maintenance (TPM) program?
Answer: Maximize equipment effectiveness by involving all employees
TPM engages all employees, including operators, in maintenance activities to maximize Overall Equipment Effectiveness (OEE).
A fleet manager notices hydraulic fluid consumption has doubled over three months. What is the BEST first step?
Answer: Conduct a fluid leak audit and inspection of hydraulic lines and seals
A systematic leak audit identifies the source of abnormal consumption before committing to costly part replacements.
In the context of repair decision-making, the 'repair vs. replace' analysis should consider:
Answer: Repair cost, remaining useful life, and replacement cost
A complete repair-vs-replace analysis weighs the cost of repair against remaining useful life, future reliability, and the cost of a replacement unit.
Which lubrication practice is considered BEST for extending bearing life in heavy equipment?
Answer: Following the manufacturer's recommended lubrication intervals and grease type
Adhering to manufacturer-specified intervals and grease specifications prevents over- or under-lubrication, both of which damage bearings.
What does the acronym OEE stand for in equipment management?
Answer: Overall Equipment Effectiveness
OEE (Overall Equipment Effectiveness) measures availability, performance, and quality to gauge how effectively equipment is utilized.
When establishing a maintenance inspection frequency for a critical excavator, a CEM should primarily base the schedule on:
Answer: Manufacturer recommendations, operating hours, and environmental conditions
Inspection frequency must account for manufacturer guidelines, actual operating hours accumulated, and the severity of the operating environment.
