Fuel Efficiency Analysis
Fuel economy in WD615-powered trucks is influenced by engine tuning, transmission matching, terrain, and load profile. In real-world conditions across the Rocky Mountain corridor (including Denver’s 1,600–2,000 m elevation), average fuel consumption is observed as follows:
| Operating Condition | Fuel Consumption (Loaded) | Notes |
|---|---|---|
| Highway (65–75 mph) | 28–31 L/100 km (8.1–8.4 mpg) | Optimized with 5.45 axle ratio |
| Mountain Grades (loaded) | 34–38 L/100 km (6.2–7.0 mpg) | Elevation and gradient impact |
| Urban/Stop-Start (dump/short-haul) | 38–42 L/100 km (5.6–6.2 mpg) | Frequent idling, low gear use |
The Weichai WD615 engine achieves best efficiency in the 1,400–1,800 rpm range. Use of the HW19710’s close-ratio top gears allows for effective cruise control and reduced lugging. Retrofitting with aftermarket engine management modules (EMMs) has shown up to 6% improvement in fuel economy, though not recommended without OEM validation.
Load Capacity & Structural Performance
These trucks are engineered for high-cycle, heavy-load applications typical in construction and aggregate hauling:
- Maximum Payload: 34.5 metric tons (76,059 lbs), compliant with CO state bridge formula and axle weight limits when properly loaded.
- Frame Strength: High-tensile C-channel frame supports side-dump, end-dump, and flatbed configurations without reinforcement under standard loads.
- Axle Durability: The HC16 tandem rear axles (featuring spiral-bevel gears and full-floating shafts) demonstrate >800,000 km mean time between failures (MTBF) in controlled fleet studies.
- Tire Load Rating: 12.00R20, 18PR tires support 2,800 kg (6,173 lbs) per tire at 850 kPa (123 psi), suitable for sustained 40-ton GVW operations.
Operational Suitability for Denver, CO

Prepared by: SEA LION International
Subject: Export Logistics Solutions for Used Trucks from China to Denver, CO, USA
Target Audience: Fleet Managers, Construction Equipment Procurement Officers
Executive Summary
This report evaluates three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of used trucks from Chinese ports to the U.S. inland market, specifically serving Denver, CO. The analysis focuses on cost-efficiency, transit integrity, equipment compatibility, and corrosion protection. A standardized wax spraying protocol is recommended to mitigate seawater-induced corrosion during ocean transit.
1. Export Route Overview
Used trucks are typically sourced from major Chinese industrial zones (e.g., Qingdao, Shanghai, Guangzhou) and shipped via Pacific Ocean routes to U.S. West Coast ports (e.g., Los Angeles, Long Beach, Tacoma). From there, overland transport via Class I rail or heavy-haul trucking delivers units to Denver, CO.
2. Shipping Method Comparison
| Parameter | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Lo-Lo) | Flat Rack Container |
|---|---|---|---|
| Loading Method | Driven on/off vessel via ramps | Lifted by crane (Lo-Lo) | Secured on open-frame container, lifted by crane |
| Vehicle Compatibility | Operational trucks only (must be drivable) | Operational or non-operational | All conditions (damaged, oversized, inoperable) |
| Cargo Security | Moderate (exposed decks) | Low (stacked loosely) | High (lashed, enclosed within container footprint) |
| Corrosion Risk | High (full seawater spray exposure) | High (deck exposure) | Moderate (partial exposure, depends on stowage) |
| Average Cost (per unit) | $1,800 – $2,400 | $1,500 – $2,000 | $2,600 – $3,500 |
| Transit Time (China → LA/LB) | 14–18 days | 16–20 days | 15–19 days |
| Inland Rail Compatibility | Standard double-stack not applicable; requires specialized auto-rack railcars | Loose cargo; requires re-handling at port | Containerized; compatible with standard intermodal rail |
| Insurance Complexity | Moderate | High (due to handling risks) | Low to moderate (standard container terms) |
| Best For | Fleet of drivable, standard-profile trucks | High-volume, low-cost export of mixed-condition units | High-value, oversized, or damaged units requiring secure transport |
3. Corrosion Protection: Wax Spraying Protocol
Seawater exposure during ocean transit presents a critical risk to undercarriages, chassis frames, and electrical components of used trucks. To mitigate long-term degradation and preserve resale value, SEA LION International mandates a pre-shipment wax spraying treatment for all exported units.
Wax Spraying Specifications:
| Parameter | Specification |
|---|---|
| Product Type | Solvent-based, salt-displacing corrosion inhibitor (e.g., DINITROL 4490, Fluid Film) |
| Application Method | High-pressure spray (200–300 psi) |
| Coverage Areas | Undercarriage, frame rails, suspension components, fuel tanks, wheel hubs |
| Film Thickness | 25–35 µm (dry film) |
| Curing Time | 4–6 hours (ambient, 20°C) prior to loading |
| Reapplication | Recommended after unloading in U.S. for resale preparation |
| Compliance | Meets ASTM D1748 (Humidity Testing of Coatings) and ISO 9223 (Corrosivity of Atmospheres) |
Note: Wax treatment is mandatory for RO-RO and Bulk Cargo shipments due to high exposure. For Flat Rack units, it remains strongly advised for long-term asset preservation.
4. Recommended Solution by Use Case
| Use Case | Recommended Method | Rationale |
|---|---|---|
| Fleet of 50+ drivable Class 8 trucks | RO-RO | Cost-effective, rapid loading, minimal port handling |
| Mixed lot (operable/inoperable units) | Flat Rack | Secure transport, accommodates non-drivable units, rail-compatible |
| Budget-driven export, low-value units | Bulk Cargo | Lowest cost, but highest risk of damage and corrosion |
| Oversized or modified construction trucks | Flat Rack | Only viable method for non-standard dimensions |
