Fault Phenomenon: SANY SAP125C paver while driving, the left track shoe suddenly detaches.

Troubleshooting Process:
– Checked pins: track pins worn and broken.
– Checked tension: track tension too loose.
– Checked drive sprocket: sprocket teeth severely worn.
– Checked carrier rollers: carrier roller seized.

Root Cause: The track tension was too loose for a long time, combined with excessive lateral force during turning, causing the track to detach from the drive sprocket.

Required Parts: Reinstall track and adjust tension, replace worn pins.
