What is interval-based maintenance?

Interval-based maintenance (TBM) is a method of planning maintenance work that is carried out on the basis of a predetermined schedule. This schedule is usually based on empirical values obtained by monitoring the operational behavior of the equipment. Interval-based maintenance is particularly suitable for plants where it is difficult to monitor the wear of components and where, at the same time, regular maintenance work is required to ensure trouble-free operation.

What is the goal of interval-based maintenance?

The aim of interval-based maintenance is to prevent unplanned downtimes due to capping parts. Historical data is used to determine the most accurate possible time period during which a machine or system is functional until capping parts lead to a malfunction or failure.

What are the advantages of interval-based maintenance?

A central advantage of interval-based maintenance is the plannability of the maintenance measures, as these are defined by a schedule. The regularity of maintenance work can reduce unplanned downtime, which in turn increases the reliability of the plant or machinery.

What are the disadvantages of interval-based maintenance?

A central disadvantage of interval-based maintenance is the possibility that maintenance measures are carried out although they would not be necessary. Likewise, failures can occur at any time that cannot be predicted because they are triggered by random events, for example.
