To keep downtimes and maintenance costs to a minimum, the technical systems in a company must be inspected and maintained regularly. For this reason, you need to understand the process of preventive maintenance.
Preventive maintenance can be categorized in the following four areas:
- Time Based
In time-based preventive maintenance, maintenance tasks are triggered after a specific time period has elapsed.
For example, every six months.
- Performance Based
In performance-based preventive maintenance, maintenance tasks are triggered when a specific amount of performance (counter reading) is reached.
For example, after every 10,000 km.
- Condition Based
In condition-based preventive maintenance, maintenance tasks are triggered when a condition is outside a specified value range.
For example, thread depth below 15 mm, or temperature higher than 85°C.
- Predictive Maintenance
Predictive Maintenance (or control machines) is cloud-based, in real-time, and predicts machine failures based on collected data (IoT application - internet of things).
Preventive Maintenance Process
The preventive maintenance process involves the planning and execution of recurring inspection and maintenance activities.
The steps in the preventive maintenance process are as follows:
The task list defines either object-dependent or object-independent process steps to be performed.
The maintenance plan is created for the object and automatically generates orders, notifications, and service entry sheets, in accordance with specific guidelines.
Scheduling is responsible for the regular call-up of orders, notifications, and service entry sheets. As well as the recalculation of planned dates.
The maintenance order is automatically generated by scheduling the maintenance plan. It is entered in the order list, from where it is processed like other orders.
The technical completion marks the order and the corresponding planned date in the maintenance plan as finished. The date of the technical completion is used in the maintenance plan for calculating the next planned date.
