Field notes
Rotating-equipment maintenance intelligence.
Technical articles on power-transmission maintenance, shaft alignment and rotating-equipment reliability — drawn from PMA field experience across the Bowen Basin conveyor fleets, not vendor marketing.
Each piece is written to be immediately useful on the asset. The aim is not to describe the theory — it is to close the gap between what a reliable programme looks like and what most fleets actually have in place.

Reading an article is one thing. Having a director review the asset against it is another. Director Les Horn reviews every enquiry — tell us the drive, the symptom and how many change-outs it has burned through.
