🔹 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.
