2 strategies to reduce equipment downtime
There are two very interesting strategies that can be developed to deal with undesirable practices. And which lead to the unforeseen stoppage of mobile and industrial machinery, with a view to eliminating defects and reaching the stage of excellence:
1- Standardized work
The level of trust and appreciation that organizations have for so-called "tribal knowledge" is high. This is unwritten knowledge based on the experience of experienced technicians and passed down from generation to generation. In many plants there is no practice of using checklists and standardized procedures when starting up and shutting down mobile and industrial equipment.
Maintenance departments do not usually adopt traceability practices when selecting and carrying out preventive or predictive maintenance tasks. Preventive maintenance regulations are often written in very general terms. For example, "check operating status of hydraulic pump". But what is included in the term "check"? Corrective maintenance plans, then, are even rarer. And when they do exist, they hardly contain details such as backlash, torque to be applied, belt tension, etc.
The fact is that without the use of standardized practices in maintenance and operation work, we cannot expect behavior and performance to reach the stage of excellence.
2- Commitment to Eliminating Defects by Finding the Root Cause
Thinking from the perspective of eliminating defects in mobile and industrial equipment, it is interesting to create a small group of highly trained technicians. However, they need the autonomy to act, correct and identify the root cause of the most important maintenance problems.
In many cases, equipment operators or maintenance mechanics are unable to accurately identify the root cause of more complex problems. And by carrying out palliative procedures, failures become recurrent.
It is important that the technical analysis group is properly trained for the role it will perform. With procedures for identifying and correcting failure modes, the operation and maintenance staff will be much more willing to accept the work plans they have been involved in drawing up.
