Choosing a Maintenance Method

In terms of Maintenance Methods, there are three choices for existing equipment. They are Operate to Breakdown, Fixed Time Maintenance, and Condition Based Maintenance. Operate to Breakdown: The equipment is run until it breaks down. Fixed Time Maintenance: The replacement of parts or equipment on a fixed/scheduled frequency.  Condition Based Maintenance: The problem is found and fixed at the time when it is discovered. It is a common assumption that Condition Based Maintenance is always the most cost effective. While this is commonly the case, it is not always true.

Equipment Doesn't Break Down, Components Do!

What is a component? IDCON uses the word “component” to describe an item that is highly repetitive for preventive maintenance purposes.  For example, the AC motor on the infeed hydraulic unit is composed of several components or machine elements. The infeed hydraulic unit is a highly repetitive unit often found in paper mills, refineries, mines, etc. AC motors are a component that is reoccurring as well.

How to Document Cost-Effective Maintenance Tasks Part 5: Equipment List

So, we have completed our Criticality Analysis. What’s next? In Part 5 of this series, we will cover the importance of using an equipment list while performing Preventive Maintenance, how to use the equipment list most effectively, and provide an example and template of a well-organized equipment list. 

How to Document Cost-Effective Maintenance Tasks Part 4: Criticality Analysis

Part 4 of this series will cover how to decide what PMs we should document first, and typically we do a criticality analysis. As we like to say at IDCON: Keep it simple. It is best to keep the criticality analysis as simple as possible. As with any type of criticality analysis, the formula is Risk x Consequence. The “risk” represents the probability of the failure or breakdown occurring, and the “consequence” could refer to safety, environmental, high cost, lost production, etc.
