Basically there are 3 types of maintenance-
- Corrective maintenance
- Preventive maintenance
- Contracted maintenance
Corrective maintenance is done when an equipment fails or doesn’t work satisfactorily.
Preventive maintenance is carried out to reduce the failure of equipment to minimum.
In contracted maintenance contact terms are agreed by the supplier of the equipment and user. It may include both preventive and corrective maintenance.
The maintenance schedule is usually in form of log sheet or which week, month, year are tabulated.
Each major equipment is provided with a history card. The details about inspection, operation and remarks are written in these cards.
The spares are kept in store with proper inventory control.
