Conveyor lines rarely fail without warning; they fail because the warning was not on anyone's checklist. A 15-minute weekly walk-down prevents most unplanned stops.
Daily and weekly checks
Listen for a change in drive noise, look for belt tracking drift, check for product debris in curves and under transfers, and confirm every emergency stop and gate interlock still trips. On chain conveyors, check chain tension and lubrication at the same interval.
Monthly tasks
Inspect wear strips and support rollers for wear, verify accumulation zone pressure, test photo-eyes and code gates with a known-good product, and check that guarding fixings are still tight. Record the findings — trends matter more than a single reading.
Failures worth pre-empting
Belt tracking drift is almost always a loading or roller-alignment problem, not a belt problem. Chain elongation past about 2 % is a replacement point, not an adjustment point. Accumulation sensors fail on dust before they fail electrically. Drive gearbox oil is the cheapest planned replacement on the line.
Keep a spare-parts kit per module family — chain section, belt length, wear strip, photo-eye, drive motor. Because BIFA modules share frames and drives across families, one kit covers a mixed line.
