Crane Slip-Contact Line Fault Handling Summary
1 There are sparks inside the sliding contact rail.
Main reason: Poor contact between the brush surface and the rail.
Handling method: Inspect the rail joints and properly lapping the brushes to ensure proper contact. 60% Contact area.
2 • The sliding contact wire swings significantly during operation.
Main reasons: The shift fork fails to absorb transmission errors; the guide rail has poor straightness; and the lifting bracket is loose.
Treatment method: Adjust the puller to ensure it can freely compensate for transmission errors; realign the guide rail for straightness; and tighten the suspension bracket screws.
3 • Brush side scratches
Main reasons: Brush wear, improper alignment of the slip-line collector; excessive lateral force transmission in the tractor's fork mechanism.
Treatment methods: Replace or adjust the spring pressure; replace the traction fork or adjust the tractor fork.
4 The current collector on the sliding contact line is making significant abnormal noises during operation.
Main reasons: Overcurrent; uneven connections.
Treatment method: Increase the number of current collectors; reinstall the rail connections.
5 • The brushes wear out quickly
Main reasons: Uneven connections; excessive current load; excessive spring pressure.
Handling method: Reconnect the rail as required; increase the number of current collectors; replace or adjust the spring pressure.
6 • Scratched housing of the slip-line collector
Main reasons: Rail deformation; inadequate collector design.
Solution: By fault 2 Handle, add shaping clips; adjust the collector.
7 • Power failure in the sliding contact line
Main reasons: The brush climbs uphill within the conduit; the brush is severely worn and no longer able to make contact with the conductor; the conductor joint is uneven; a single collector is being used; and the rail joint has come loose.
Troubleshooting steps: Check if the collector is severely worn and replace it; replace the brushes; readjust the connection points; install a dual-brush collector; and re-tighten the connecting screws.
8 • Rail deformation, hindering the movement of the collector
Main reasons: Excessively high ambient temperature; large or loose spacing of the hanging racks.
Treatment method: Use thermal insulation panels locally and add sunshades outdoors; increase the number of sliding contact wire suspension brackets, straighten the conduits, and tighten the screws.
