What is preventive maintenance?

What is preventive maintenanceRegardless of the industry, sudden failures often prove to be costly operations. Preventive maintenance helps prevent unplanned production downtime and the associated multiplier effects. It is also a cost-effective method of servicing machinery and equipment.

What does preventive maintenance mean?

Preventive maintenance includes periodic tasks, such as time-based maintenance-critical measures. The method may include inspection tasks, needs-based measures, and maintenance measures related to condition monitoring with visual inspections. The goal of preventive maintenance is to try to prevent faults or detect any emerging fault before they occur.

Preventive maintenance is often largely tied to the calendar and recent events. In order to gain the full benefits of preventive maintenance, it is also essential to monitor the usage time and methods of the machine and to plan preventive maintenance accordingly.

The preventive maintenance method is based on RCM analysis

Reliability Centered Maintenance (RCM) is a method that can be used to develop preventive maintenance. RCM was developed in the 1960s for the needs of aviation, but it is still applied in a variety of industries.

The method aims at improved safety, productivity and usability, as well as cost-savings. The purpose of the RCM method is to achieve the required levels of safety and availability of the equipment.

In practice, preventive maintenance consists of a set of tasks that are obtained as a result of an RCM analysis. The RCM analysis consists of, among other things:

  • defining functionally significant maintenance items
  • defining the causes of failures
  • defining the effects of failures (cost and time) and their probability
  • identifying effective maintenance tasks to prevent failures

Why is preventive maintenance worth it?

It is often thought that implementing preventive maintenance raises maintenance costs, especially in the early stages. These costs usually include maintenance hours, service and materials.

When preventive maintenance is targeted at critical equipment and resourced properly, it is soon apparent that the payback period can be really short. If, on the other hand, unplanned disruptions are priced, it can be said that preventive maintenance is significantly more cost-effective than corrective maintenance from the outset.
