1. Technical Application & Operational Rationale

SEA LION International specifies compact bucket-wheel excavators (typically 150-350 kW drive power, bucket capacity 0.3-0.8 m³) as critical assets for high-efficiency, low-impact continuous excavation in spatially constrained or cost-sensitive operations. Unlike conventional hydraulic excavators, SBWEs deliver:

• Continuous Material Flow: Eliminates digging/swing/dump cycles, enabling 20-35% higher material throughput (m³/hr) in friable to semi-abrasive materials (overburden, coal, sand, urban fill).
• Reduced Ground Pressure: Optimized crawler design (≤ 0.7 kg/cm²) minimizes surface disruption on soft terrain or paved logistics yards.
• Precision Grading: Integrated laser/GNSS guidance achieves ±10 mm contour accuracy, critical for final grade preparation in construction or stockpile management.
• Lower Fuel Consumption: Steady-state operation reduces specific fuel consumption by 15-25% compared to equivalent hydraulic excavators performing cyclic loading.

This platform excels in:
Narrow-Pit Mining: Lignite, sand, or gravel extraction where bench width restricts larger shovels.
Logistics Terminals: Continuous loading/unloading of bulk materials (coal, biomass) at river ports or rail sidings.
Urban Construction:* Trenching for utilities, basement excavation in confined sites, and precise slope finishing.

Fuel Efficiency Analysis

The BWX-120S is engineered for optimal fuel economy in continuous excavation and material handling operations. The Weichai WD615 engine incorporates high-efficiency combustion technology and precise electronic fuel injection (EUI), resulting in a typical fuel consumption of 18.5–22.0 L/h under standard load conditions (80% capacity operation).

• Idle Fuel Consumption: 5.2 L/h
• Peak Efficiency Point: Achieved at 1,600–1,800 rpm during steady-state cutting
• Fuel Savings Technology: Integrated engine-transmission control logic reduces lugging and over-revving, improving fuel efficiency by up to 12% compared to prior-generation models

Based on a 10-hour shift at average load, the machine consumes approximately 200–210 L/day, translating to ~25.8 L/1,000 m³ processed (at 800 m³/h average throughput). This positions the BWX-120S among the most fuel-efficient small-class bucket wheel excavators in its operational class.

4. Corrosion Mitigation: Wax Spraying Protection

Marine transport exposes steel components to chloride-laden atmospheres, accelerating galvanic and pitting corrosion. SEA LION International mandates the application of industrial-grade anti-corrosion wax as a preventive measure for all SBWE exports.

Wax Spraying Protocol:

Parameter	Specification
Wax Type	Solvent-based, hydrophobic, salt-excluding polymer blend
Application Method	High-pressure spray (15–20 bar)
Coverage Areas	Undercarriage, slewing ring, hydraulic cylinders, exposed welds, ladder joints
Film Thickness	50–75 µm (measured via wet-film gauge)
Curing Time	24 hours (ambient 25°C, 50% RH)
Protection Duration	Up to 12 weeks at sea
Removal	Biodegradable citrus-based solvent or high-pressure wash (post-delivery)

Note: Wax treatment is strongly recommended for RO-RO and Bulk Cargo shipments due to prolonged deck/hold exposure. Flat Rack units benefit from dual protection—structural containment and wax barrier.

---

5. Recommendation Matrix

Priority	Recommended Method	Rationale
Cost Optimization	Bulk Cargo	Lowest freight cost; acceptable for inland destinations with rapid offloading
Speed & Simplicity	RO-RO	Minimal handling; ideal for operational units near RO-RO ports
Maximum Asset Protection	Flat Rack + Wax Spray	Superior control over environmental exposure and mechanical stress
Corrosion-Prone Routes (e.g., Southeast Asia, Middle East, West Africa)	Flat Rack + Wax Spray	Combined physical and chemical defense against marine salinity

---

6. Operational Guidelines for Export from China

1. Pre-Shipment Preparation:
2. Drain hydraulic systems or fill with inhibitor fluid.
3. Fold or disassemble boom/ladder per IEC 60204-1 standards.

4. Apply wax spray 48 hours prior to loading; document coverage.

5. Port of Loading:

6. Primary ports: Shanghai, Qingdao, Nansha (all support RO-RO and container services).

7. Ensure flat rack availability 72 hours in advance.

8. Documentation:

9. Certificate of Conformity (GB/T 19001-2016)
10. Bill of Lading, Packing List, ISF Filing (for U.S. destinations)
11. Anti-Corrosion Treatment Certificate (issued by certified applicator)

---

7. Conclusion

For small bucket wheel excavators exported from China, Flat Rack shipping combined with industrial wax spraying offers the highest integrity for long-term asset performance, particularly in high-humidity and saline environments. While RO-RO provides operational efficiency and Bulk Cargo offers economy, neither matches the protective capability of Flat Rack units with proactive corrosion barriers. SEA LION International recommends wax-based protection as non-negotiable for all maritime exports, regardless of shipping method.
