Problems on this page:

Belt tracking or tension faults

Hits OEE: Availability

Symptoms: Spiral belt mistracks, tension alarms, stops on the tower.

Tension or take-up off
Set belt tension/take-up; check the overdrive (low-tension) cage.
Cage/drum slip or build-up
Clean the cage/drum; check the friction drive.
Belt wear or damaged links
Inspect and replace worn belt sections.

Prevention: Tension/cage setup, cleaning, belt-condition checks.

Product temperature out of spec

Hits OEE: Quality

Symptoms: Product too warm/cold leaving the spiral, downstream issues.

Airflow or refrigeration fault
Check fans, coils and refrigeration capacity.
Dwell/belt speed wrong
Match belt speed to required cooling/freezing time.
Loading or air short-circuiting
Improve loading and air management/baffles.

Prevention: Airflow/refrigeration upkeep, correct dwell, loading control.

Jams or product transfer faults

Hits OEE: Availability

Symptoms: Product jams at infeed/discharge transfers, fallen product, stops.

Transfer timing or guide fault
Adjust transfer plates, guides and timing.
Product variation or sticking
Manage product handling; check release/coatings.
Belt or sprocket wear
Service sprockets and belt; check engagement.

Prevention: Transfer setup, product handling, drive maintenance.

Stop the same fault coming back

Recurring spiral conveyor stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
