Fuel Efficiency Analysis
Fuel economy in Gray Daniels units equipped with the Weichai WD615 engine and HW19710 transmission is influenced by load profile, terrain, and driver behavior. Under standardized testing conditions (SEA LION Field Cycle 2026 – 60% highway, 30% on-grade, 10% idle), average fuel consumption is as follows:
- Loaded (35–40 tons GCW): 28–32 L/100 km
- Unloaded / Light Duty: 22–26 L/100 km
- Idling Consumption: ~2.1 L/hr (engine at 850 rpm)
The Weichai WD615 engine features high-pressure common rail (HPCR) fuel injection (on Euro III variants), enabling optimized combustion and reduced particulate emissions. When paired with disciplined gear-shifting practices using the HW19710’s wide-ratio spread, fuel efficiency improves by up to 8–12% compared to unoptimized operation.
Note: Retrofit ECU tuning and exhaust brake integration are recommended for mountainous routes to enhance fuel control and reduce brake wear.
Load Capacity & Structural Integrity
Gray Daniels trucks in this configuration are engineered for high-cycle, heavy-load operations:
- Max Payload Capacity: 30,000–33,000 kg (66,139–72,753 lbs), depending on body configuration (dump, flatbed, or lowboy).
- Axle Load Distribution: Designed for even weight transfer across tandem rear axles with optional load-balancing beams.
- Frame Reinforcement: Critical stress points (king pin, suspension mounts, fifth wheel) are inspected and reinforced during refurbishment.
- Overload Tolerance: Tested up to 110% of rated GVWR for short-duration hauls (≤50 km); not recommended for sustained overloads.
These units are frequently deployed in quarry, dam construction, and road base transport where durability under repetitive shock loading is essential.
Operational Recommendations
- Maintenance Interval: Oil and filter change every 10,000 km; fuel system inspection every 20,000 km.
- Transmission Care: Use SAE 80W-90 GL-5 gear oil; check shift linkage alignment monthly.
- Tire Monitoring: Maintain inflation at 90 psi (6.2 bar); inspect for sidewall cracking and tread chunking bi-weekly in abrasive environments.
- Cooling System: Clean radiator fins weekly in dusty conditions to prevent WD615 overheating.
Conclusion
The Gray Daniels used truck platform with Weichai WD615 engine, HW19710 transmission, and 12.00R20 tire setup offers a cost-effective, robust solution for construction fleets requiring high payload capacity and mechanical reliability. With proper maintenance, these units demonstrate a remaining service life of 3–5 years under moderate-to-heavy use, making them ideal for capital-efficient fleet expansion.

| Maximum Asset Protection | Flat Rack + Tarping | Optimal corrosion and impact resistance |
| Remote Port Delivery | Bulk Cargo (with wax+) | Only viable option for non-RO-RO ports; requires strict wax adherence |
| Mixed Fleet (Running/Non-Running) | Hybrid: RO-RO + Flat Rack | Operational units via RO-RO; damaged/oversize in Flat Racks |
5. Compliance & Documentation
All shipments must include:
– Pre-shipment inspection (PSI) certificate
– Wax application log (batch number, coverage photo)
– Lashing plan (for non-RO-RO methods)
– Bill of Lading with cargo condition note
Conclusion
For the export of Gray Daniels used trucks from China, RO-RO shipping is the optimal solution for operational units due to cost and speed. Flat Rack containers are recommended for high-value or non-operational units requiring maximum protection. Bulk cargo remains a fallback for remote destinations, though with higher risk. Industrial wax spraying is non-negotiable across all methods to ensure structural integrity upon arrival.
SEA LION International advises integration of wax protocols into pre-shipment SOPs and preference for RO-RO lanes where port infrastructure permits.
