| Curb Weight | ~10,500 kg (23,148 lbs) |
| Max Payload Capacity | Up to 29,500 kg (65,036 lbs) under optimal conditions |
Fuel Efficiency Analysis
Fuel economy in used Howo tractor units varies based on engine calibration, load profile, terrain, and maintenance history. Field data from fleet operators indicate the following average performance:
| Operating Condition | Average Fuel Consumption |
|---|---|
| Highway (Loaded, 25–30T) | 28–32 L/100 km |
| Mixed Terrain (On/Off-road) | 34–38 L/100 km |
| Idle & Low-Speed Operation | Up to 42 L/100 km (construction zones) |
Notes:
– The Weichai WD615 series is known for robustness but lags modern Euro V/VI engines in fuel optimization.
– Retrofitting with aftermarket fuel injectors, optimized air filters, and tire pressure monitoring systems (TPMS) can improve efficiency by 8–12%.
– Engine remapping (where compliant) may yield marginal gains but increases wear on older units.
Load Capacity & Operational Suitability
The Howo ZZ4257 platform is engineered for high gross combination weights (GCW), with typical configurations supporting:
| Parameter | Value |
|---|---|
| Max GCW (Truck + Trailer) | 60,000–65,000 kg (132,277–143,300 lbs) |
| Recommended Trailer Type | 3-Axle semi-trailer (flatbed, lowboy, or dump) |
| Towing Coupling | Jost-type 2″ kingpin, rated for 16,000 kg vertical load |
Structural Highlights:
– Reinforced chassis frame (300 mm high-strength steel, U-section)
– High-torque rear axles with 5.45 final drive ratio (standard), enabling operation on 8–10% gradients under full load
– Load distribution optimized for 33/67 front-to-rear axle bias under full GVWR
Maintenance & Fleet Considerations
- Engine Longevity: WD615 units typically achieve 800,000–1,000,000 km before major overhaul, assuming regular oil and filter changes.
- Transmission Durability: HW19710 gearbox is field-rebuildable; common failure points include synchro wear after 500,000 km without proactive servicing.
- Tire Life: 12.00R20 18PR tires last 80,000–120,000 km depending on road surface and inflation management.
- Spare Parts Availability: High global inventory; OEM and third-party components readily available in Africa, Middle East, Southeast Asia, and South America.
Conclusion
The used Howo tractor truck remains a viable asset for cost-conscious fleet operators in construction and heavy haulage. While not matching the fuel efficiency or emissions standards of newer platforms, its high load capacity, rugged drivetrain, and low maintenance costs deliver strong total cost of ownership (TCO) in non-urban environments. Proper pre-purchase inspection focusing on engine compression, transmission wear, and frame integrity is recommended to ensure operational reliability.

| Best Suited For | Operational vehicles, large volumes | Non-operational, cost-sensitive loads | High-value units, sensitive markets |
3. Corrosion Protection: Wax Spraying System
3.1. Requirement
Exposure to marine atmospheric conditions and saltwater spray during transit poses a significant corrosion risk to undercarriages, chassis frames, and engine compartments of used Howo trucks.
3.2. Recommended Solution: Industrial Wax Spraying
| Parameter | Specification |
|---|---|
| Product Type | Solvent-based anti-corrosion wax |
| Application Method | High-pressure spray (undercarriage + chassis) |
| Coverage Area | Frame rails, suspension mounts, fuel tanks, exhaust system |
| Film Thickness | 80 – 120 microns |
| Salt Spray Resistance | ASTM B117: 500+ hours |
| Drying Time | 2 – 4 hours (ambient) |
| Service Life (transit + storage) | 6 – 12 months (non-tropical) |
| Reapplication Requirement | Post-delivery inspection recommended |
3.3. Process Flow
- Pre-Cleaning: High-pressure freshwater wash to remove contaminants.
- Degreasing: Alkaline solution to remove oil and grease.
- Drying: Forced-air drying (80°C for 30 min).
- Wax Application: Automated spray booth; full underbody coverage.
- Curing: Ambient cure (minimum 4 hours) before loading.
Note: Wax protection is mandatory for RO-RO and Bulk Cargo; recommended for Flat Rack in tropical or high-humidity routes.
4. Risk Assessment & Mitigation
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack | Mitigation Strategy |
|---|---|---|---|---|
| Seawater Corrosion | High | Very High | Medium | Wax spraying + desiccant in cabs |
| Physical Damage | Medium | High | Low | Lashing compliance (DNV/IACS standards) |
| Delay in Discharge | Low | Medium | Low | Pre-book terminal slots |
| Customs Inspection Delays | Low | Medium | Low | Complete documentation (CI, BL, COO) |
| Theft/Vandalism | Low | Medium | Low | GPS tracking, port security coordination |
5. Recommendations
| Use Case | Recommended Method | Rationale |
|---|---|---|
| High-volume export (>15 units), operational trucks | RO-RO | Fast loading, lower cost per unit, efficient for drivable fleets |
| Non-operational or damaged units | Bulk Cargo | Cost-effective; accommodates non-drivable units |
| Premium markets (Middle East, Africa, S. America) | Flat Rack | Maximum protection, compliance with import standards, reduced insurance claims |
| Humid or tropical destinations | All methods + wax spray | Corrosion prevention critical; wax film extends asset life post-delivery |
6. Compliance & Documentation
All shipments must comply with:
– IMDG Code (for fuel tanks with residual diesel)
– CSS Code (Cargo Securing Manual for lashing)
– ISPS Code (port security)
– Certificate of Origin (China Chamber of International Commerce)
– Pre-shipment Inspection Report (SASO, SONCAP if required)
7. Conclusion
For the export of used Howo Tractor Trucks from China, RO-RO offers the optimal balance of cost and efficiency for operational units. Flat Rack is superior for high-integrity delivery in corrosion-prone regions, while Bulk Cargo remains a budget option with elevated risk. Industrial wax spraying is non-negotiable for long-sea transits, reducing post-import refurbishment costs by up to 40%.
SEA LION International recommends integrated logistics planning combining method-specific lashing, anti-corrosion protocols, and real-time tracking to ensure fleet integrity and on-time delivery.
