EXECUTIVE OVERVIEW: STRATEGIC SOURCING OF REFURBISHED HEAVY-DUTY TRUCKS
1. Operational Imperative in Target Sectors
Fleet downtime and capital expenditure volatility remain critical constraints in mining, logistics, and construction operations. New truck acquisition costs (averaging $185,000–$250,000 for Class 8) strain CAPEX budgets, while OEM service networks in remote project sites (e.g., African mines, Siberian quarries, Southeast Asian infrastructure corridors) exhibit >30-day parts lead times. SEA LION International addresses this through a vertically integrated refurbished truck program, sourcing rigorously vetted used assets from regulated North American markets (including New Hampshire dealerships) and deploying industrial-grade refurbishment protocols.
2. Core Technical Advantage: The SEA LION Refurbishment Standard
Unlike conventional used truck dealers, SEA LION implements ISO 9001-certified refurbishment processes focused on mission-critical systems for harsh environments. Key differentiators include:

Performance Analysis
Fuel Efficiency
Fuel economy in WD615-powered units is strongly influenced by transmission calibration and duty cycle. Units equipped with the HW19710 transmission demonstrate improved cruise efficiency due to the overdrive 9th and 10th gears, reducing engine RPM at highway speeds. Field data from NH-based fleets indicates:
– Empty return runs: Up to 3.6 km/L (8.5 mpg)
– Loaded haul (25–30 tons aggregate): 2.6–3.0 km/L (6.1–7.0 mpg)
– Idling reduction systems (aftermarket retrofits) yield 8–12% fuel savings during lay periods.
The Weichai WD615’s electronically controlled high-pressure common rail (HPCR) system contributes to consistent combustion efficiency, especially when maintained per OEM intervals.
Load Capacity & Structural Integrity
The standard 6×4 configuration with dual 13T rear axles supports payloads up to 32,000 kg (70,740 lbs) on GVWR-limited routes. This makes the platform ideal for:
– Crushed stone and asphalt hauling
– Heavy equipment transport (lowboy applications)
– Longitudinal timber and steel beam logistics
Axle load distribution complies with New Hampshire RSA 235:12, allowing full legal loading on state highways without special permits under standard conditions.
Tire selection (12.00R20, 18PR) ensures high load reserve and cut resistance, critical in construction site environments with debris and uneven terrain. Tire life averages 80,000–100,000 km under proper inflation and alignment.
Operational Recommendations
- Pre-Purchase Inspection Focus: Verify turbocharger health, EGR cooler integrity (on Euro IV models), and HW19710 shift rail wear.
- Maintenance Interval: Oil and filter change every 15,000 km; fuel system service every 60,000 km.
- Cold Weather Adaptation: Ensure block heater functionality and winter-grade lubricants (10W-30 or 5W-40) for reliable NH winter operation.
Conclusion
Used trucks featuring the Weichai WD615 engine and HW19710 transmission represent a cost-effective, high-payload solution for construction and bulk transport fleets in New Hampshire. With proper maintenance, these units deliver reliable performance, competitive fuel economy, and full compliance with regional weight and durability requirements.

| Flat Rack | Medium | 85–90% reduction (with tarp + wax) | 12 months (standard maintenance cycle) |
Note: Wax treatment must be applied 72 hours prior to shipment and post-wash degreasing (ISO 8501-1 Sa 2.5 standard).
4. RECOMMENDATIONS BY USE CASE
| Client Profile | Recommended Method | Rationale |
|---|---|---|
| Fleet Managers (High Utilization, Fast Deployment) | RO-RO + Wax Spray | Rapid offload, minimal reconditioning, cost-effective for operational units |
| Construction Firms (Heavy Equipment, Mixed Conditions) | Flat Rack + Wax + Tarp Cover | Full structural protection, accommodates non-running units, ideal for excavators or crane trucks |
| Budget-Focused Importers (High Volume, Lower Value Units) | Bulk Cargo + Mandatory Wax | Lowest upfront cost; wax mitigates worst-case corrosion but requires post-arrival refurbishment |
5. OPERATIONAL INTEGRATION GUIDELINES
- Pre-Shipment Inspection (PSI): Conducted per ISO 3987, including fluid levels, battery isolation, and tire pressure stabilization (to 1.8 bar).
- Securing Protocols: Lashing with Grade 80 chain binders (RO-RO), twist locks (Flat Rack), or steel cables (Bulk).
- Documentation: CMR, Bill of Lading, SGS Inspection Certificate, and Wax Application Log (traceable by batch number).
6. CONCLUSION
For used truck exports from China, RO-RO offers optimal balance for operational fleets, while Flat Rack provides superior protection for high-value or damaged units. Bulk Cargo remains viable only with strict wax corrosion control and post-arrival refurbishment planning. SEA LION International enforces mandatory wax spraying across all shipments to ensure compliance with ISO 9001 and ISO 14001 asset preservation standards.
Future deployments will integrate IoT humidity sensors in Flat Rack units for real-time corrosion risk monitoring (pilot phase Q3 2026).
