Preventive maintenance involves regular, planned maintenance activities designed to prevent equipment failures before they occur. These activities are scheduled at specific intervals (e.g., daily, weekly, monthly, annually) based on manufacturers' recommendations or operational needs.
Key Tasks:
Regular inspections and cleaning.
Lubrication of moving parts.
Replacing worn-out components like filters, seals, and belts.
Checking fluid levels (e.g., hydraulic, coolant).
Tightening fasteners and checking alignment.
Calibration of instruments or machinery.
2. Corrective Maintenance (CM)
Corrective maintenance is performed after a piece of equipment breaks down or malfunctions. The goal is to restore the equipment to normal operating conditions.
Key Tasks:
Identifying the cause of failure.
Replacing damaged or malfunctioning components.
Repairing broken parts, such as motors, gears, or hydraulic pumps.
Testing the equipment post-repair to ensure proper functioning.
