1. Executive Summary
This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of Daewoo Tractor Trucks from manufacturing facilities in China to global destinations. The analysis focuses on operational efficiency, cost structure, equipment safety, and corrosion mitigation, with specific emphasis on wax-based protective treatments to prevent seawater-induced degradation during transit.
2. Equipment Overview: Daewoo Tractor Truck
| Parameter | Specification |
|---|---|
| Gross Vehicle Weight (GVW) | 25,000 – 32,000 kg |
| Dimensions (L×W×H) | 7.2 m × 2.5 m × 3.8 m (avg.) |
| Drive Configuration | 6×4 / 8×4 |
| Engine Type | Diesel, Euro V/VI Compliant |
| Chassis Material | High-tensile steel, corrosion-prone |
| Pre-Shipment Condition | Operational, fueled, battery-ready |
3. Shipping Method Comparison
| Criteria | RO-RO Shipping | Bulk Cargo Shipping | Flat Rack Container |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed onto vessel | Craned or driven into hold | Craned onto open-top flat rack |
| Cargo Capacity per Vessel | 150–300 units | 50–100 units (mixed load) | 1–2 units per 40′ FR container |
| Port Infrastructure | Requires RO-RO terminal | Standard bulk terminal | Container terminal with heavy lift |
| Transit Time (China–MENA) | 18–24 days | 22–28 days | 20–25 days |
| Handling Risk | Low (minimal lifting) | High (crane dependency) | Moderate (lifting required) |
| Security & Vandalism | Moderate (open decks) | Low (enclosed holds) | High (exposed, but sealed lashings) |
| Insurance Cost Index | 1.0 (baseline) | 1.3 | 1.2 |
| Average Cost per Unit (USD) | $1,100 – $1,400 | $1,600 – $2,000 | $1,800 – $2,300 |
| Best Suited For | High-volume, time-sensitive exports | Mixed heavy machinery shipments | Oversized or non-operational units |
Notes:
– RO-RO offers fastest turnaround at origin/destination ports.
– Bulk Cargo increases exposure to salt-laden air and condensation in holds.
– Flat Rack allows full access for pre-treatment and post-arrival inspection.
4. Corrosion Protection: Wax Spraying Protocol
Seawater exposure during maritime transit poses a significant risk to high-tensile steel chassis, engine compartments, and undercarriage components. SEA LION International mandates the Electrostatic Wax Spraying (EWS) System as per ISO 9227 (salt spray testing standard) for all Daewoo Tractor Trucks exported from coastal Chinese ports.
4.1 Wax Spraying Specifications
| Parameter | Requirement |
|---|---|
| Wax Type | Solvent-free, cationic microcrystalline polymer |
| Application Method | Electrostatic spray + brush detailing |
| Coating Thickness | 25–35 µm (chassis), 15–20 µm (exposed panels) |
| Coverage Areas | Frame rails, suspension mounts, fuel tanks, axle housings |
| Drying Time (Pre-Loading) | 4 hours minimum at 25°C |
| Salt Spray Resistance (ASTM B117) | >1,000 hours (no red rust) |
| Reapplication Requirement | Post-delivery inspection recommended |
4.2 Integration by Shipping Method
| Method | Wax Application Feasibility | Post-Transit Wax Integrity |
|---|---|---|
| RO-RO | High (on-site at terminal) | Moderate (deck exposure) |
| Bulk Cargo | Medium (pre-stowage only) | Low (humidity in holds) |
| Flat Rack | High (full access) | High (drainage + airflow) |
Recommendation: Flat Rack combined with EWS delivers optimal corrosion protection for long-haul routes (>20 days) through tropical or high-humidity zones.
5. Operational Recommendations
-
For High-Volume Contracts (≥50 units):
Utilize RO-RO with centralized wax spraying at Shanghai or Qingdao RO-RO terminals. Leverage economies of scale and rapid vessel turnaround. -
For Mixed Equipment Fleets:
Combine Daewoo Tractor Trucks with other machinery via Bulk Cargo, but apply wax treatment at OEM facility pre-shipment. Include desiccant bags in enclosed compartments. -
For Critical Infrastructure Projects (Remote Sites):
Deploy Flat Rack containers with full wax encapsulation. Enables crane-offloading at undeveloped ports and reduces on-site reconditioning.
6. Compliance & Documentation
All shipments must include:
– Certificate of Conformity (CoC) for wax application
– Marine Corrosion Protection Log
– Bill of Lading specifying stowage method
– Cargo Securing Report (lashing points per CSS Code)
7. Conclusion
RO-RO remains the most cost-efficient and rapid method for large-scale Daewoo Tractor Truck exports from China. However, Flat Rack shipping with electrostatic wax spraying provides superior asset protection for mission-critical deployments in corrosive marine environments. SEA LION International advises fleet managers and construction logistics teams to align shipping mode with project timeline, destination port capability, and long-term equipment integrity requirements.
