CORE ASSET PROFILE & OPERATIONAL RELEVANCE

SEA LION International leverages rigorously refurbished heavy-duty trucks originally deployed in San Antonio, TX – a region characterized by extreme thermal cycling (45°C+ ambient), high-dust environments, and continuous heavy-load operations (e.g., aggregate transport, pipeline logistics). These assets, primarily comprising SINOTRUK HOWO 8×4 T7H, SHACMAN X3000 6×4, and XCMG Mining Series HD-797B variants, undergo certified recommissioning to meet ISO 9001:2015 standards. Key applications include:

Sector	Primary Use Case	Critical Performance Metrics
Mining	Overburden haulage (open-pit)	Payload capacity: 85-120 MT; Gradeability: 32% @ full load
Construction	Heavy equipment transport (road/rail)	GVWR: 80,000 lbs; Fifth-wheel rating: 100,000 lbs
Logistics	Long-haul bulk commodities (cement, ore)	Fuel efficiency: 4.2-5.1 MPG @ 65,000 lbs GCWR

San Antonio’s operational profile subjects trucks to accelerated wear on drivetrains, cooling systems, and structural components – creating a uniquely validated asset pool for global deployment in comparable extreme environments.

Fuel Efficiency Analysis

Fuel economy in trucks equipped with the Weichai WD615 engine and HW19710 transmission is influenced by load profile, terrain, and driving behavior. Under typical construction and regional hauling conditions in South Texas:

• Average Fuel Consumption: 28–34 L/100 km (6.9–8.3 mpg)
• Optimal Efficiency Range: Achieved at 1,400–1,800 rpm with proper gear utilization
• Fuel Type: Ultra-Low Sulfur Diesel (ULSD), compatible with 5% biodiesel (B5)

The HW19710 transmission enables precise gear spacing, reducing lugging and over-revving. When paired with a calibrated rear axle ratio (typically 5.26:1 or 5.73:1), these trucks maintain engine efficiency during sustained climbs and loaded cruising on I-10 and US-90 corridors.

Note: Retrofitting with auxiliary fuel filters and engine monitoring systems can improve long-term fuel consistency and reduce downtime in dusty construction environments.

---

Load Capacity & Operational Suitability

These trucks are engineered for high-cycle, heavy-load applications common in aggregate, asphalt, and bulk material transport:

Load Metric	Capacity
Payload Capacity	Up to 28,000–32,000 kg (61,700–70,500 lbs)
Axle Load Distribution	Front: ~6,500 kg / Rear Tandem: ~21,000–23,000 kg
Dump Body Compatibility	Up to 20–25 cu yd rigid or transfer dump bodies
Tire Load Margin	15–20% safety margin under full GVWR

The 12.00R20 18PR tires provide robust sidewall strength and heat resistance, essential for off-road job sites and prolonged operation on unimproved roads. Their wide footprint reduces ground pressure, improving traction on loose or uneven surfaces.

---

Field Recommendations

• Pre-Purchase Inspection Focus: Verify ECU logs for over-speed events, inspect turbocharger condition, and check rear axle seals for leaks.
• Maintenance Priority: Regular oil analysis for Weichai engines; synchronize clutch and transmission service with brake relining cycles.
• Application Fit: Ideal for short-haul construction logistics within a 300-mile radius of San Antonio, especially in Bexar, Comal, and Atascosa counties.

---

Conclusion: Used trucks in the San Antonio market with Weichai WD615 engines, HW19710 transmissions, and 12.00R20 tires offer proven durability and cost-effective performance for medium- to heavy-duty construction fleets. With proper maintenance, these units deliver reliable service life beyond 800,000 km, making them a strategic asset for high-utilization operations.

1. Executive Summary

This report evaluates optimal maritime transport methods for exporting used trucks from Chinese ports to San Antonio, TX, via U.S. Gulf Coast terminals. SEA LION International presents a comparative analysis of three primary shipping modalities—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container transport—focusing on cost-efficiency, cargo integrity, transit reliability, and corrosion mitigation. Special emphasis is placed on wax-based anti-corrosion protection systems to ensure vehicle integrity during sea transit.

---

2. Market Context

Used truck demand in San Antonio, TX, continues to grow due to infrastructure expansion and fleet modernization cycles. Chinese export hubs (e.g., Shanghai, Qingdao, Guangzhou) offer competitive pricing on used commercial vehicles. SEA LION International facilitates end-to-end logistics, including port loading, marine protection, customs clearance at U.S. ports (e.g., Port of Houston), and inland drayage to San Antonio.

4. Corrosion Protection: Wax Spraying System

Marine environments expose metallic surfaces to chloride-laden aerosols, accelerating oxidation. SEA LION mandates electrostatic wax spraying for all used truck shipments:

• Application Method: Automated undercarriage and chassis spray at origin depot (China).
• Coating Type: Solvent-free, hydrophobic microcrystalline wax (ASTM D127 compliant).
• Thickness: 25–30 µm uniform layer on frame rails, suspension components, and exhaust systems.
• Performance:
• Salt spray resistance: >1,000 hours (per ASTM B117)
• UV stability: 90 days minimum
• Removability: Biodegradable citrus-based solvents (post-delivery)

Verification Protocol:
Each unit receives a corrosion protection certificate with batch ID, application timestamp, and QC inspection tag.

---

5. Recommended Solution for San Antonio Market

Factor	Recommended Method
Cost-Sensitive Fleets	RO-RO (optimal balance)
Non-Operational Units	Bulk Cargo (if structurally sound)
High-Value or Older Models	Flat Rack + Wax Protection
Fleet-Wide Shipments (10+ units)	RO-RO with batch wax treatment

SEA LION Advisory: For San Antonio-bound consignments, RO-RO is preferred for operational trucks due to faster turnaround, lower handling risk, and compatibility with wax-protected undercarriages. Flat Rack is advised for trucks with oversized dimensions or custom modifications.

---

6. Compliance & Documentation

All shipments comply with:
– IMSBC Code (Bulk)
– CTU (Cargo Transport Unit) Code (Flat Rack)
– IMO RO-RO Safety Guidelines
– U.S. EPA and DOT import standards for used vehicles
– Chinese Customs Export Declaration (Form EX-9)

---

7. Conclusion

For construction firms and fleet managers sourcing used trucks from China, SEA LION International recommends RO-RO shipping with electrostatic wax corrosion protection as the optimal logistics solution for San Antonio, TX deliveries. This method ensures structural integrity, regulatory compliance, and minimized downtime post-import. Bulk cargo is viable only for non-running units, while Flat Rack offers premium protection at increased cost.

Future integration of IoT humidity sensors within transport units is under pilot for Q3 2026 to enhance real-time condition monitoring.
