A global online retailer kept standing down whole shifts to conveyor failures it never saw coming - monthly thermal sweeps caught nothing between visits, and by the time a belt was loud enough to notice, the line was already down. The failures that matter most, like an over-tensioned belt running hot, develop in the weeks between sweeps, where nobody's looking.
This case study shows how continuous infrared monitoring closed that blind spot: catching the slow, dangerous failures while they're still a work order, not a stopped line - and changing how a lean team maintains the belts a whole shift depends on.
