Outlining Preventive Maintenance

Objective

After completing this lesson, you will be able to explain key elements of Preventive Maintenance

What is Preventive Maintenance?

Preventive Maintenance covers regular inspections and maintenance tasks. The target is to automatically generate maintenance orders at regular intervals.

The image shows the areas of Preventive Maintenance: time-based, performance-based, condition-based and predictive.
  • Time-Based - reacts on preset time periods
  • Performance-Based - reacts on counter readings
  • Condition-Based - monitors specific parameters and their thresholds
  • Predictive - proactively predicts failures

Watch the following video to learn about the concept of Preventive Maintenance.

Task Lists

In your company, all the inspection and maintenance tasks that must be performed at regular intervals are defined in maintenance task lists. For this reason, you need to understand maintenance task lists.

Maintenance task lists describe a series of individual maintenance activities including required spare parts. You can use the task lists to standardize recurring activities, plan them more effectively and save time when you create maintenance orders and maintenance plans.

Task lists can be object-dependent (such as equipment plans and plans for a functional location) and refer to only one technical object. or object-independent task lists (such as general maintenance task lists) can be used for multiple objects of the same type.

Single-Cycle versus Strategy Maintenance

To minimize downtimes and maintenance costs, the technical systems in a company are inspected and maintained regularly. You want to understand the plans that can help you manage this maintenance. For this reason, you need to understand single cycle plans (time-based) and strategy plans (time-based).

This image shows an example for single-cycle maintenance: regular inspection of a portable fire extinguisher.

Single cycle plans are used to manage the maintenance of machines and operational systems, which are always inspected and/or maintained in the same way at fixed intervals.

In this plan, the same activity is executed at regular intervals.

Some examples of a single cycle plans are as follows:

  • Annual inspection of fire extinguishers
  • Technical inspection every two years

Strategy plans can be used to manage maintenance activities of a car in the following ways:

  • Check air filter every 6 months
  • Check fan belt every 12 months

The following video provides an information about the maintenance plan, i.e., scheduling data and maintenance items.

Maintenance Plan Scheduling

The system has to continuously monitor the inspection tasks and maintenance tasks that the planner schedules in the form of maintenance plans. You want to understand how the scheduling is done. For this reason, you need to know how to schedule maintenance plans.

What does Scheduling a Maintenance Plan mean?

Scheduling maintenance plans means to ...

  • start newly created maintenance plans.
  • permanently monitor all active maintenance plans.
  • recalculate plan dates, if necessary.
  • create call objects such as orders, notifications or service entry sheets.
