TPM Concept and Implementation Approach

The following is a Maintainability Design Checklist for coal mining equipment. The purpose of the checklist is to provide a summary of design review points for the maintainability assessment of new or existing underground equipment. It specifically focuses on the identification of equipment design features, tasks, or procedures that impact equipment downtime, repair costs, labor hours and maintainer skill level requirements.

Although safety and risk mitigation is a fundamental part of creating value and boosting profits, it is not the end of the story when it comes to asset management. To realize the true value of an asset across its entire lifecycle, a business must ensure it has a set of key building blocks in place. These consist of forward-looking management structures and processes that adopt a broader perspective than just identifying and addressing threats and vulnerabilities.

Unfettered expression and spiritual satisfaction? How does this relate to managing a maintenance department, especially one in the U.S. Postal Service? Open your mind. Take a page from the Zen Buddhist monks who preach: When you are quiet and listen, you become aware of sounds not normally heard. USPS maintenance leaders are listening and beginning to understand that maintenance success doesn't come through closed minds and closed doors.

The component importance measure is an index of how much or how little an individual component contributes to the overall system reliability. It is useful to obtain the reliability importance measure or value of each component in the system prior to investing resources toward improving specific components. This is done to determine where to focus resources in order to achieve the most benefit from the improvement effort.

Which costs are we interested in? Which cost is it that we're really focused on targeting? That we're saying as a team here. We're doing a business case now. Which costs can we drive down through reliability? "All of them." Agreed. Long term.

While off-line filtering and particle analysis were key to Smoky Canyon Mine’s reliability improvements, the mine’s reliability team found that these techniques did not do enough to warn about catastrophic failures in the mine’s fleet of 785 Caterpillar haul trucks. Therefore, the team decided to include magnetic plug inspections in the 500-hour interval inspections. Smoky Canyon Mine’s magnetic plug inspections have raised its reliability maintenance program beyond contamination control to the next level.

Learn to Sell...Do not dismiss this statement thinking it does not apply to your situation because you are not a roving consultant or contractor. In-house maintenance reliability professionals need to exhibit the same, or even better, customer service when it comes to driving change or pulling their organization toward a path of continuous improvement.
