Types of Preventive Maintenance

Preventive maintenance is a fundamental strategy to ensure equipment reliability and optimize resources. There are various approaches that can be combined to meet the specific needs of each organization:

1. Time-based maintenance:

   Tasks are executed at previously set intervals, based on manufacturer instructions, industry standards, or internal policies. This approach includes actions such as regular inspections, lubrication, cleaning, and replacement of components to maintain consistent asset performance.

2. Usage-based maintenance:

   This method, ideal for assets with variable demands, organizes maintenance activities according to operating hours or recorded usage cycles, optimizing performance in assets experiencing intensive wear and tear.

3. Condition-based maintenance (CBM):

   Thanks to real-time monitoring with advanced sensors, equipment status is analyzed. Interventions are performed only as conditions require, ensuring more efficient management and reducing unnecessary expenses.

4. Reliability-centered maintenance (RCM):

   Consists of replacing components or systems before they reach the end of their estimated life or exceed known failure rates, preventing interruptions and ensuring continuity of operations.

5. Proactive replacement or renewal:

   Involves the early replacement of components or systems based on their expected life expectancy or known failure rates, avoiding operational interruptions and improving continuity of operations.

These methods can be combined to create a comprehensive maintenance strategy that minimizes downtime, prolongs equipment lifespan, and optimizes resource management in any industrial environment.
