Maintenance Systems

Reactive maintenance

Advantage:

• "Drive to breakage" - this concept means little effort for maintenance; just until the machine fails

Disadvantage:

• Increased costs due to unforeseen downtime

• Increased staff costs, especially for jobs requiring overtime

Preventive maintenance

Advantage:

• Fixed maintenance intervals reduce machine downtime. Compared to the reactive maintenance, a cost saving of approx. 12% (pure material input) can be achieved.

Disadvantage:

• A Maintenance based on time intervals leads to increased staff costs and high costs for spare parts, since components with remaining service life may also be replaced.

Predictive maintenance or condition-based maintenance

Advantage:

• The permanent monitoring detects damage to components already in the development.

• Maintenance work is therefore carried out only as needed and can be planned in good time.

• Compared to preventive maintenance, a further cost savings of about 18% can be achieved. Costs for machine and process stoppages are thereby reduced.

• Costs for personnel and spare parts are also reduced.

Disadvantage:

• The costs of traditional surveillance systems such as thermography and vibration analysis can be very high.
