Product Usage Guide
The king pin is a critical component that connects the semi-trailer to the tractor unit. Proper installation and maintenance are essential for safe operation.
- Installation: Should be performed by a qualified technician. Ensure the king pin is securely welded or bolted according to the trailer manufacturer's specifications. Proper alignment with the fifth wheel is crucial to prevent uneven wear and potential accidents.
- Maintenance: Regularly inspect the king pin for signs of wear, corrosion, or cracks. Check for any looseness in the assembly. Lubricate the king pin according to the recommended schedule to ensure smooth coupling and uncoupling with the fifth wheel.
- Safety Warning: Never operate a trailer with a damaged or excessively worn king pin. A failure of this component can lead to trailer separation, resulting in severe accidents. Always adhere to the maximum payload capacity (28T for this model).
