Fault Phenomenon: Bomag BF600C paver middle conveyor belt runs off to one side and rubs during operation.

Troubleshooting Process:
– Checked drums: drive drum or tension drum not parallel.
– Checked belt: belt splice not straight or damaged.
– Checked idlers: idlers not turning freely.
– Checked material discharge: material falling on one side of belt.

Root Cause: The two sides of the conveyor belt tension drum are adjusted unevenly, causing the drum axis to be non-perpendicular to the belt centerline, leading to tracking issues.

Required Parts: Readjust tension drum parallelism.
