🔹 Production Completion & Pre-Delivery Inspection (PDI)

Once semi trailers complete manufacturing and internal quality control, the following steps must be carried out before client hand-over:

• Structural weld inspection (visual and nondestructive if required).
• Testing of all mechanical systems — brakes, landing gear, suspension, coupling mechanism.
• Electrical and lighting system check, label & VIN plate verification.
• Documentation compilation — build sheets, test certificates, export packing list.

🚢 Stacking Trailers for RORO Shipping

For export via Ro-Ro (roll-on/roll-off) vessels, multiple trailers are often **stacked vertically** or **nested** to maximise deck loading. This requires special loading jigs, secure lashing, and strict compliance with ship stability rules.

• Ensure kingpin locking system is engaged if front trailer nests into the rear of lower.
• Use steel chocks, lashing chains rated for sea transit (typically 10 t WLL or higher).
• Calculate combined height, weight and centre of gravity to maintain ship stability certificate.

🧮 Technical Specifications for Stacking

Parameter	Requirement	Notes
Maximum Stack Height	2 trailers high (common); check ship deck limits	Dependent on deck deck-strength and lashing points
Combined Gross Weight	≤ 40 t per stack row typical	Check each trailer weight + lashing hardware
Lashing Points	Minimum 4 approved points per trailer	ISO 1161 or equivalent standards recommended
Seafastening Time	~2–4 hours per stack	Labour and vessel cost factor

🔧 Port Delivery & Customer Hand-Over

After RORO unloading at destination port, the following hand-over steps should be completed:

• Inspect for damage from sea voyage — rust, paint chips, deformation.
• Verify each trailer’s IDs, build numbers, weight, and corrective actions if needed.
• Configure landing legs and tyres for local operation — many arrive with locked parking brake.
• Provide client with full document pack: user manual, warranty terms, maintenance schedule.

📍 Export & Logistics Considerations

• Select **deep-water terminals** capable of handling large RORO vessels (e.g., Rotterdam, Hamburg, Istanbul / Turkey).
• Ensure compliance with **IMO stowage** rules for weight and height segregation.
• Use certified sea-fastening hardware and label each trailer stack with “No access during transit”.

📝 Checklist Before Dispatch

• Trailer build complete & PDI passed
• Stack jigs and lashing pads verified
• Export packing list, bill of lading, certificate of origin ready
• Client contact briefed and set for arrival reception

Conclusion:
Semi trailer delivery for export involves much more than manufacture — the stacking, RORO loading, sea-fastening, and final hand-over require detailed coordination between manufacturing, logistics, and operations teams. Following structured technical protocols ensures trailers arrive intact, ready for operation, and with client satisfaction high.
