(Note: "Tractor seat" is commonly referred to as a "fifth wheel coupling" or "traction coupling" in industry terminology.)
First 5,000 km Service:
Clean all lubricated components thoroughly.
Reapply high-quality heavy-duty grease after removing debris or burrs from the traction pin.
Ensure grease channels are fully coated to enhance wear resistance and prolong service life.
Recommended: Use lithium-based or Shacman spare parts extreme-pressure (EP) grease for optimal performance.
Avoid Unnecessary Adjustments:
Never pull the adjustment lever (e.g., release handle) indiscriminately during use.
Improper handling accelerates wear and may cause mechanical locking mechanisms to bind, leading to excessive friction and component failure.
Follow Manufacturer Instructions: Operate the coupling system according to the designated workflow.
Optimal Alignment:
Ensure the trailer's connecting plate is positioned 0–50 mm lower than the upper plane of the traction coupling.
Incorrect height (too high/low) may cause coupling misalignment, operational instability, or equipment damage.
Pre-Coupling Check: Verify the trailer and coupling are level before connecting.
Inspect Regularly: Check for grease contamination, corrosion, or mechanical wear.
Clean Critical Components: Remove dirt and debris from the traction pin and locking mechanism after off-road use.
Monitor Wear Indicators: Replace parts showing significant wear shacman truck parts (e.g., worn traction pins, cracked plates).
Proper maintenance and operation of the traction coupling ensure:
✅ Smooth transportation performance
✅ Extended component lifespan
✅ Reduced downtime and repair costs
Always consult your semi-trailer manufacturer’s manual for model-specific guidelines.
