Performance Analysis

Fuel Efficiency

The Weichai WD615 engine, while not meeting Euro VI standards, is optimized for fuel economy under heavy-load, low-speed conditions typical in on/off-road construction hauling. Average fuel consumption ranges from:

• 28–34 L/100 km (8.3–6.9 mpg) under mixed load and terrain
• 24–27 L/100 km (9.8–8.7 mpg) on consistent haul routes with proper driver training

Fuel efficiency is significantly influenced by transmission use. The HW19710 10-speed gearbox allows precise gear selection, enabling operators to maintain engine RPM within the optimal torque band (1,400–1,800 rpm), reducing lugging and over-revving. Use of cruise control (where equipped) and load-matched gear shifting improves fuel economy by up to 12% in repetitive operations.

Load Capacity & Structural Integrity

These dump trucks are engineered for high-cycle, high-payload operations. With a GVWR of 40 metric tons and tandem rear axles rated at 16,000 kg each, they support payloads up to 28 metric tons when equipped with a reinforced 22 m³ body. The HC16 rear axles feature high-strength alloy gears and heat-treated shafts, providing extended service life under sustained overloads (up to 110% of rated capacity for short durations).

The 12.00R20 20PR tires are designed for cut and abrasion resistance, with deep tread patterns suitable for unpaved roads, quarries, and muddy sites. These tires support a maximum single-load rating of 3,000 kg per tire at 850 kPa inflation, ensuring stability and reduced ground pressure.

---

Operational Recommendations

• Engine Maintenance: Regular DPF (if retrofitted) and EGR system cleaning recommended; use of CF-4 or CH-4 grade lubricants.
• Transmission Care: Check gear oil (85W-90 GL-5) every 20,000 km; inspect shift linkage wear.
• Axle Monitoring: Monitor differential oil condition and axle seal integrity, especially after water fording.
• Tire Management: Maintain inflation at 830–850 kPa; rotate front tires every 15,000 km to extend life.

---

Conclusion

Used dump trucks equipped with the Weichai WD615 engine and HW19710 transmission offer a cost-effective, high-payload solution for construction fleets operating in developing infrastructure zones. While emissions standards are pre-Euro V, their mechanical robustness, ease of repair, and availability of spare parts make them a practical choice for high-utilization scenarios. With proper maintenance, these units deliver over 800,000 km of service life, making them a viable mid-tier asset in mixed fleet operations.

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 used Mack dump trucks from Chinese ports to global destinations. The analysis focuses on cost-efficiency, cargo integrity, transit timelines, and corrosion mitigation, with specific emphasis on wax-based protective treatments against seawater exposure during transit.

Used heavy-duty dump trucks, particularly Mack models, retain high residual value in emerging markets across Africa, Southeast Asia, and Latin America. SEA LION International provides end-to-end export logistics from major Chinese ports (Shanghai, Qingdao, Guangzhou) with engineered solutions to ensure asset preservation throughout ocean transport.

Comparative Analysis: RO-RO vs. Bulk Cargo vs. Flat Rack

Parameter	RO-RO	Bulk Cargo	Flat Rack
Definition	Vessels designed for wheeled vehicles to drive on/off via ramps	Loose stowage in open cargo holds; trucks secured with lashing	Open-sided containers; trucks secured on flat platforms
Loading/Unloading Speed	High (≤ 4 hrs per truck)	Medium (requires crane/lifting gear)	Medium to High (depends on port crane availability)
Cargo Protection	Moderate (exposed to salt air; limited weather shielding)	Low (fully exposed to elements, moisture, debris)	High (customizable tarping, partial enclosure options)
Corrosion Risk	High (direct seawater spray, humidity)	Very High (prolonged exposure, poor ventilation)	Moderate (mitigated via sealing and wax protection)
Cost per Unit (USD)	$1,200 – $1,600	$900 – $1,300	$1,800 – $2,400
Insurance Complexity	Low (standardized vehicle coverage)	Medium (higher claim risk)	High (customizable but higher premium)
Port Infrastructure Required	RO-RO terminal with ramp access	General cargo berth with lifting cranes	Container terminal with heavy-lift capability
Ideal for Fleet Size	5+ units (economical at scale)	10+ units (low-value, high-volume)	1–5 units (high-value, precision transport)
Transit Time (China → West Africa Example)	28–35 days	30–40 days	26–32 days (frequent container schedules)

Note: All cost estimates include inland transport to port, documentation, and terminal handling fees (THC) as of Q1 2026.

Corrosion Protection: Wax Spraying Protocol

Seawater-induced corrosion is a critical risk during maritime transport, particularly for undercarriages, hydraulic systems, and electrical components of used dump trucks. SEA LION International implements an industrial-grade wax spraying protection system compliant with ISO 12944 standards for marine environments.

Wax Spraying Process:

1. Pre-Treatment Cleaning: High-pressure freshwater wash to remove salt residues, dust, and hydrocarbons.
2. Dehumidification: Interior cabin and engine bay dried using portable industrial dehumidifiers.
3. Application: Electrophoretic wax emulsion (Ceresin-based, 18–22 μm thickness) applied via electrostatic spray to:
4. Chassis rails
5. Suspension components
6. Wheel hubs and brake assemblies
7. Underbody electrical conduits
8. Curing: 4-hour ambient cure cycle prior to loading.
9. Post-Transit Removal: Biodegradable solvent-based stripper recommended upon delivery.

Performance Metrics:

Protection Layer	Salt Spray Resistance (ASTM B117)	Service Life During Transit	Removability
Standard Wax Spray	480 hours	Up to 45 days	High (non-residual)
Enhanced (Additive: ZnO nanoparticles)	720 hours	Up to 60 days	Medium

Recommendation: Wax spraying is mandatory for RO-RO and Bulk Cargo shipments. Advised for Flat Rack when transiting high-humidity zones (e.g., equatorial Pacific, Indian Ocean).

---

Recommended Transport Strategy by Use Case

Fleet Size	Destination Region	Recommended Method	Rationale
1–3 units	Middle East, Central Asia	Flat Rack	High asset value protection, schedule reliability
4–10 units	West Africa, Southeast Asia	RO-RO	Cost-effective, fast turnaround, established routes
10+ units	South America, Caribbean	Bulk Cargo (with wax protection)	Lowest cost per unit; acceptable risk with mitigation

---

Compliance & Documentation

All exports comply with:
– China Customs Code (CCC-HE) for used heavy equipment
– IMO/ILO/UNECE CTU Code for cargo securing
– ISPM 15 (if wooden dunnage used)
– Bill of Lading, Export Declaration, Pre-Shipment Inspection (PSI) as required

---

Conclusion

For the export of used Mack dump trucks from China, RO-RO offers the optimal balance of speed and cost for mid-to-large fleets, while Flat Rack provides superior protection for high-value, low-volume shipments. Bulk Cargo remains viable only when paired with rigorous wax-based corrosion control.

SEA LION International recommends mandatory wax spraying for all maritime shipments to ensure operational readiness upon arrival and minimize post-import refurbishment costs.

Ongoing R&D in hydrophobic polymer coatings is expected to further reduce corrosion risk in 2027–2028 logistics cycles.
