Technical Specifications & Parameters

Industrial Specification Report 2026

Prepared for Fleet Managers & Construction Companies
Subject: Technical Evaluation of Used Heavy-Duty Trucks – San Antonio Market

This report provides a detailed technical specification analysis of commonly available used heavy-duty trucks in the San Antonio region, focusing on models equipped with the Weichai WD615 engine platform. These units are frequently sourced from regional haulers, quarry operators, and infrastructure contractors, making them a cost-effective option for fleet expansion or project-based operations.

---

Technical Specifications: Used Heavy-Duty Trucks (San Antonio Market)

Parameter	Specification	Notes
Engine Model	Weichai WD615.69 / WD615.50	6-cylinder, inline, water-cooled diesel; widely serviced across Texas
Displacement	9.726 L	Optimized for high torque at low RPM
Horsepower	336 hp @ 2,200 rpm	Peak output suitable for heavy hauling and on/off-road applications
Max Torque	1,400 N·m @ 1,200–1,600 rpm	High low-end torque ideal for steep grades and loaded starts
Transmission	Fast Gear HW19710	10-speed manual; robust synchromesh design; common in Chinese-origin heavy trucks
Gear Ratios	10F + 2R (1st: 12.88, 10th: 0.78, R: 12.47)	Optimized for multi-terrain performance
Front Axle Load	7,000 kg (15,432 lbs)	Reinforced I-beam; suitable for rough site access
Rear Axle Load	2 × 11,500 kg (2 × 25,351 lbs)	Dual tandem setup with spiral-bevel gears; high durability

Fuel Tank Capacity	300–400 L (dual tank configuration)	Extended range for remote operations

---

Fuel Efficiency Analysis

Fuel consumption in the Weichai WD615-powered units averages 28–34 L/100 km (6.9–8.3 mpg US) under mixed operating conditions, depending on load profile and terrain. In controlled highway testing (loaded at 85% GVWR), fuel economy stabilizes at approximately 30 L/100 km (7.8 mpg). The engine’s Bosch electronic unit pump (EUP) system ensures precise fuel delivery, contributing to consistent efficiency in stop-start hauling cycles.

Fuel efficiency can be further optimized through:
– Regular injector calibration
– Use of OEM-recommended 15W-40 CI-4 diesel oil
– Tire pressure monitoring (critical for 12.00R20 load management)

Note: Units with aftermarket ECU tuning may show inflated power claims but often suffer 10–15% higher fuel consumption and reduced engine longevity.

---

Load Capacity & Operational Suitability

These trucks are routinely deployed in:
– Aggregate hauling (quarry to plant)
– Heavy equipment transport (lowboy applications)
– Road construction material delivery

With a Gross Vehicle Weight Rating (GVWR) of up to 49 tonnes, and tandem rear axles rated at 23,000 kg combined, the platform supports maximum payload capacities of 30–35 tonnes depending on body configuration and regional axle weight regulations.

The 12.00R20 18PR tires are load-rated for 3,600 kg per tire at 830 kPa (120 psi), making them suitable for sustained operation at high GVW. However, fleet managers should inspect tread depth and casing integrity—common wear points in Texas’ abrasive caliche terrain.

---

Recommendations for Fleet Integration

1. Pre-Purchase Inspection Focus Areas:
2. Turbocharger health (common failure point at >600,000 km)
3. Clutch wear (HW19710 requires proper adjustment)

4. Frame rail corrosion (salt and moisture exposure in southern TX)

5. Maintenance Schedule:

6. Oil and filter: Every 10,000 km
7. Transmission fluid (GL-5 85W-90): Every 40,000 km

8. Axle lubricant: Every 50,000 km

9. Parts Availability:
   Weichai and Fast Gear components are widely stocked in San Antonio and Houston, with local service centers offering warranty-backed remanufactured units.

---

Conclusion: Used trucks in the San Antonio market featuring the Weichai WD615 engine and HW19710 transmission offer a high torque-to-cost ratio, suitable for demanding construction and bulk transport applications. With proper maintenance, these units deliver reliable service life beyond 800,000 km, making them a strategic asset for cost-conscious fleet operators.

Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared by: SEA LION International
Subject: Logistics Solutions for Exporting Used Trucks from San Antonio via Chinese Ports
Target Audience: Fleet Managers & Construction Companies

---

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 trucks originating in San Antonio, USA, and transshipped through Chinese export hubs. The analysis focuses on operational efficiency, cost implications, cargo integrity, and corrosion protection during transit. A specialized wax-based anti-corrosion treatment is recommended to mitigate seawater exposure risks.

---

1. Overview of Export Logistics Chain

Used trucks from San Antonio are transported via rail or heavy-haul trucking to Chinese transshipment ports (e.g., Qingdao, Shanghai, or Ningbo) for global re-export. These vehicles are typically destined for markets in Africa, the Middle East, and South America. The choice of shipping method significantly impacts delivery timelines, vehicle condition upon arrival, and total landed cost.

---

2. Comparative Analysis of Shipping Methods

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo (Loose Stowage)	Flat Rack Container
Loading Mechanism	Self-driven on/off vessel	Craned or forklift loaded	Craned onto open-frame container
Cargo Protection	Moderate (exposed decks)	Low (stacked, minimal cover)	High (enclosed sides optional)
Vehicle Capacity	High (100–500+ units per vessel)	Variable (depends on hold size)	Low (1–2 units per 40′ FR)
Transit Time	Fast (direct routes available)	Moderate	Moderate to Slow (container ops)
Port Infrastructure	Requires RO-RO terminal	General bulk terminal	Standard container terminal
Handling Risk	Low (drivable access)	High (lifting, contact damage)	Medium (lifting required)
Cost per Unit (USD)	$800–$1,200	$600–$900	$1,800–$2,500
Best For	High-volume, operable trucks	Non-operational, stripped units	Oversized or damaged units

---

3. Corrosion Protection: Wax Spraying Treatment

Maritime transport exposes vehicles to high-humidity, salt-laden environments, accelerating corrosion on undercarriages, brake lines, and chassis components. To ensure long-term asset integrity, industrial-grade wax spraying is mandatory for all exported units.

3.1 Wax Spraying Specifications

Feature	Specification
Application Method	High-pressure electrostatic spray
Coverage Areas	Undercarriage, wheel wells, frame rails, suspension
Wax Type	Solvent-based, salt-excluding polymer blend
Thickness	50–75 μm (microns) uniform layer
Salt Spray Test (ASTM B117)	Pass: >500 hours without red rust
Drying Time	30–45 minutes (ambient 25°C)

3.2 Benefits

• Forms hydrophobic barrier against seawater ingress
• Reduces maintenance costs post-delivery by up to 40%
• Extends resale value in tropical and coastal markets
• Compatible with pre-shipment inspection standards (e.g., JAA, SGS)

---

4. Recommendations

Use Case	Recommended Method	Rationale
High-volume, driveable fleets	RO-RO + Wax Spray	Cost-efficient, rapid loading, minimal handling damage
Non-operational or salvage units	Bulk Cargo + Wax Spray	Lower cost; suitable for craned loading despite higher risk
Oversized, crane-equipped trucks	Flat Rack + Wax Spray	Accommodates dimensions exceeding standard containers

Note: All shipments must undergo wax protection pre-loading. SEA LION International mandates third-party verification of coating integrity before vessel acceptance.

---

5. Compliance & Certification

All export shipments must comply with:
– IMSBC Code (for bulk cargo stowage)
– CTU Code (for containerized units)
– RO-RO Safety Guidelines (IMO Resolution MSC.267(85))
– Customs Declaration (China Customs Tariff #8704.00)

Pre-shipment inspection (PSI) by accredited agencies is required for import clearance in target markets.

---

Conclusion

For fleet managers and construction firms exporting used trucks from San Antonio via China, RO-RO shipping combined with industrial wax spraying offers the optimal balance of cost, speed, and asset preservation. Bulk cargo remains viable for non-operational units where cost is primary, while flat rack solutions serve niche oversized requirements. Proactive corrosion protection is non-negotiable for maintaining vehicle integrity across global supply chains.
