Fuel Efficiency Analysis

Fuel consumption is measured under ISO 9249-compliant test conditions simulating mixed operation (40% digging, 30% swinging, 30% travel).

• Average Fuel Consumption: 28–32 L/h during peak load operations
• Cruising Efficiency (Travel Only): 18–22 L/h at 25 km/h on graded haul roads
• Fuel Tank Capacity: 350 L
• Estimated Operational Range: 10–12 hours at 65% load factor

The Weichai WD615 engine, while not meeting latest Tier IV Final emissions standards, maintains robust fuel delivery calibration and high torque retention at low RPMs (peak torque: 880 N·m @ 1,400 rpm), contributing to stable efficiency in stop-start excavation cycles. Fleet telemetry data from 2024–2025 deployments indicates a 12–15% increase in fuel use compared to newer electronically controlled engines, but with significantly lower maintenance overhead.

Note: Units retrofitted with fuel optimization kits (e.g., calibrated injectors, turbo upgrades) have demonstrated up to 8% improvement in fuel economy under consistent load profiles.

---

Load Capacity & Structural Performance

• Maximum Digging Depth: 6,800 mm
• Maximum Reach at Ground Level: 9,900 mm
• Swing Torque: 42 kN·m
• Tractive Effort: 165 kN

The HW19710 transmission provides 4 forward and 4 reverse gears with two-speed range selection, enabling precise control in high-resistance digging and efficient travel across unpaved terrain. Axle load distribution (42% front / 58% rear) ensures stability during lifting operations within SAE J1097-rated zones.

• Lift Capacity (Over Front, 6m radius): 3,100 kg
• Tipping Load (Static, Full Boom Extension): 6,200 kg

Tires (12.00R20) are rated for 3,600 kg per tire at 5 bar inflation, suitable for soft to medium-compacted surfaces. Field reports indicate acceptable wear life of 1,800–2,400 operating hours depending on terrain abrasiveness and load adherence.

---

Summary for Fleet Deployment

Used small excavators equipped with the Weichai WD615/HW19710 drivetrain offer a cost-effective solution for mid-intensity construction cycles where availability and mechanical simplicity outweigh emissions compliance requirements. With proper maintenance, these units sustain 6,000–8,000 total operating hours before major overhaul. Their predictable load behavior and high axle capacity make them suitable for integration into mixed-age fleets operating in rural infrastructure, pipeline, and municipal projects.

Recommendation: Conduct pre-acquisition inspection focusing on transmission bearing play, axle seal integrity, and tire casing fatigue—common wear points after 4,000+ hours.

3. Corrosion Protection: Wax Spraying System

Marine environments expose metal surfaces to salt-laden air and condensation, accelerating corrosion during transit (average humidity: 75–95% RH). To mitigate degradation of hydraulic cylinders, undercarriage, and pivot joints, SEA LION International mandates a wax-based anti-corrosion treatment prior to shipment.

3.1. Wax Spraying Protocol

Step	Procedure	Specification
1	Surface Preparation	Degrease, dry, remove loose debris
2	Application Method	High-pressure electrostatic spray
3	Coating Type	Solvent-free, hydrophobic microcrystalline wax
4	Layer Thickness	25–35 µm (uniform coverage)
5	Curing Time	4–6 hours at 20°C
6	Protected Zones	Tracks, boom pins, hydraulic rods, radiator fins

3.2. Performance Metrics

Property	Value
Salt Spray Resistance (ASTM B117)	>500 hours (no red rust)
Water Displacement	>98%
Temperature Stability	-20°C to +60°C
Removability	Biodegradable citrus-based solvent

Compliance: Meets ISO 12944-2:2019 (Corrosion Protection of Steel Structures) and JIS Z 0302 (Marine Transport Preservation).

---

4. Risk Mitigation & Recommendations

Risk Factor	RO-RO	Bulk Cargo	Flat Rack
Corrosion	Moderate	Low	High (exposure)
Structural Damage	Low	High	Moderate
Theft/Vandalism	Low (secured decks)	Moderate (hold access)	High (exposed units)
Delays (Port Congestion)	Low	Moderate	High (container queues)

Recommended Use Cases:

• RO-RO: Optimal for fleet managers exporting 10+ units with operational mobility. Offers fastest turnaround and lowest handling risk.
• Bulk Cargo: Suitable for budget-driven projects where equipment will undergo full refurbishment post-import.
• Flat Rack: Recommended only for excavators with attachments (e.g., breakers, augers) or non-functional undercarriages.

---

5. Conclusion

For the export of used small excavators from China, RO-RO shipping provides the best balance of cost, speed, and equipment protection, particularly when combined with industrial-grade wax spraying. While Bulk Cargo offers lower base rates, increased damage risk offsets savings. Flat Rack should be reserved for exceptional dimensional cases.

SEA LION International advises all clients to implement mandatory pre-shipment wax encapsulation and GPS-enabled telematics tagging for real-time monitoring of environmental exposure during transit.
