Which of the following are the three main categories of maintenance?

The three main categories of maintenance are predictive, preventive, and corrective maintenance.

Predictive maintenance involves forecasting potential equipment failures using advanced techniques such as data analysis and monitoring, allowing maintenance to be performed just before a failure occurs. This approach helps in minimizing unexpected downtimes and reduces unnecessary maintenance work.

Preventive maintenance is scheduled regularly to ensure that equipment continues to operate efficiently and effectively. This type of maintenance is aimed at preventing problems before they occur through routine checks, servicing, and adjustments.

Corrective maintenance refers to actions taken to repair equipment after a failure has occurred. This type of maintenance is necessary when equipment breaks down or malfunctions despite preventive measures.

These three categories encompass a comprehensive strategy for maintaining equipment, focusing on reliability, efficiency, and minimizing costs associated with failures and repairs.
