OPERATIONAL IMPERATIVES & MARKET SHIFT

Global infrastructure expansion and resource extraction demands necessitate cost-optimized, high-availability earthmoving assets. New equipment capital expenditure (CAPEX) constraints, coupled with extended project timelines in emerging economies, have driven strategic adoption of certified pre-owned excavators. SEA LION International identifies a critical market shift: fleet managers prioritize Total Cost of Ownership (TCO) over initial purchase price, demanding reliability parity with new units at 30-45% reduced acquisition cost.

PREFERRED MODEL: XCMG XE370G (REFURBISHED STANDARD)

Why this platform dominates target regions:

Regional Market	Operational Challenge	XE370G Refurbished Advantage	SEA LION Value Add
Africa	Extreme dust, abrasive ore, limited service infrastructure	Reinforced undercarriage (Grade 3), sealed hydraulic systems, simplified maintenance access	On-site technical support teams, genuine XCMG parts depots in Johannesburg & Dar es Salaam
Russia (Siberia)	-50°C operation, permafrost, remote sites	Cold-start kits (-45°C certified), reinforced boom/stick, thermal management upgrades	Winterization protocols, containerized logistics via Vladivostok hub
Southeast Asia	High humidity, monsoon conditions, dense urban sites	Corrosion-resistant coatings, enhanced cooling circuits, low-ground-pressure undercarriage	Monsoon-ready certification, RO-RO shipments to Tanjung Pelepas/Laem Chabang

KEY DRIVERS FOR REGIONAL PREFERENCE

1. TCO Optimization: Refurbished XE370G units achieve >92% operational availability (vs. 85% industry avg. for non-certified used) through SEA LION’s 127-point refurbishment standard.
2. Parts Ecosystem Security: Direct access to OEM-sourced XCMG components eliminates downtime from counterfeit parts (a 37% failure cause in unregulated markets – 2025 CIMAC Field Study).
3. Logistics Resilience: SEA LION’s dedicated RO-RO vessels (China → Durban/Donghae/Vladivostok) reduce transit time by 18 days vs. spot charter, with climate-controlled container options for electronics.
4. Regulatory Compliance: Units delivered with region-specific certifications (GOST-R for Russia, SABS for Africa, ASEAN WRV for SEA), including mine safety retrofits.

SEA LION’S REFURBISHMENT DIFFERENTIATOR

Our 18-year expertise in heavy equipment export enables beyond-OEM rebuild protocols:
– Hydraulic Systems: Full circuit flushing, new pumps/motors, ISO 16/14/11 particulate standard certification.
– Structural Integrity: Ultrasonic testing of booms/sticks; fatigue-crack remediation per BS 7910.
– Electronics: CAN bus diagnostics reset, software updated to latest regional emission profiles.

CONCLUSION

The XCMG XE370G (refurbished to SEA LION Standard SLS-2026) delivers new-equipment performance at 65% of CAPEX while mitigating operational risks inherent in Africa, Russia, and Southeast Asia. For fleet managers, this translates to 22% lower 5-year TCO versus non-certified alternatives. SEA LION’s integrated model—combining OEM-partnered refurbishment, strategic parts warehousing, and engineered logistics—provides the asset security required for multi-year resource projects in volatile environments. This is not a cost-saving measure; it is a strategic operational enabler for sustainable fleet growth.

Performance Analysis

Fuel Efficiency

Reconditioned units equipped with the Weichai WD615 engine demonstrate an average fuel consumption of 28–32 L/100 operating hours under mixed-load conditions (digging, swinging, loading). At steady-state excavation (medium load, 70% duty cycle), fuel efficiency improves to 24–26 L/hour. The HW19710 transmission contributes to optimized gear engagement, reducing lugging and overspeeding—critical for fuel conservation in repetitive cycle operations.

Fuel efficiency is further enhanced by:
– Reconditioned fuel injection systems calibrated to OEM tolerances.
– Cleaned and backflushed cooling circuits ensuring optimal combustion temperature.
– Standard installation of fuel monitoring telematics in post-2024 refurbishments.

Load Capacity & Structural Integrity

The total operating weight of 22,500 kg ensures stability during high-torque operations. The axle load distribution (front: 7,800 kg, rear: 12,200 kg) reflects counterweight-assisted balance, critical for lift and swing operations. The HW19710 transmission is rated for 197,000 N·m input torque capacity, providing robust power delivery under peak load.

Tires (12.00R20, 16PR) are load-rated for continuous off-road use with a per-tire capacity of 5,800 kg, supporting full-machine weight with a 1.3x safety margin. Tread depth post-refurbishment is maintained at ≥70% of OEM spec (minimum 22/32″), ensuring traction on loose or uneven terrain.

---

Operational Recommendations

• Daily Inspection: Verify transmission oil level, tire pressure (95–105 psi), and axle seal integrity.
• Fuel Management: Use #0 diesel with cetane booster in sub-10°C environments to prevent WD615 injector fouling.
• Load Monitoring: Avoid sustained operation above 90% torque for >30 minutes to prevent thermal degradation of HW19710 synchros.

---

Conclusion:
The Weichai WD615-powered excavator with HW19710 transmission and 12.00R20 tire configuration offers a balanced solution for mid-size earthmoving fleets. With verified fuel efficiency and robust load-handling capability, these reconditioned units deliver cost-effective uptime in quarry, roadwork, and foundation applications. SEA LION International recommends integration into mixed fleets where operational predictability and parts commonality are prioritized.

3. Corrosion Protection: Wax Spraying Treatment

3.1 Importance

Used excavators are highly susceptible to marine atmospheric corrosion during ocean transit due to salt-laden air, humidity, and potential seawater splashing. Critical zones include:

• Hydraulic cylinder rods
• Track links and rollers
• Electrical connectors
• Boom/pivot joints

3.2 Recommended Protection Protocol: Wax-Based Anti-Corrosion Spray

Feature	Specification
Product Type	Solvent-based, hydrophobic wax emulsion
Application Method	High-pressure spray (minimum 30 psi)
Coverage Areas	All exposed metal surfaces, undercarriage, joints
Thickness Required	25–50 µm uniform film
Drying Time	2–4 hours (ambient 25°C)
Seawater Resistance	Up to 45 days immersion (ISO 9227 salt spray)
Post-Transit Removal	Biodegradable solvent or steam wash
Compliance	ISO 12944-2 (C5-M marine environment)

Note: Wax application must occur within 48 hours of final cleaning and prior to loading. Reapplication is recommended if transit exceeds 40 days.

---

4. Method-Specific Recommendations

4.1 RO-RO Shipping

• Advantages: Fast loading, minimal mechanical stress, ideal for functional units.
• Limitations: Limited to operational machines; not suitable for disassembled components.
• Corrosion Mitigation: Wax spray + sealed cab + silica gel desiccants inside operator cabin.

4.2 Bulk Cargo

• Advantages: Lower cost; accommodates non-functional units.
• Limitations: Risk of shifting; exposure to condensation in hold.
• Corrosion Mitigation: Full wax treatment + breathable VCI (Vapor Corrosion Inhibitor) wraps on sensitive components.

4.3 Flat Rack Containers

• Advantages: Accommodates oversized excavators; standard container logistics.
• Limitations: Exposure to weather; requires tarpaulin cover.
• Corrosion Mitigation: Wax spray + waterproof tarp secured with straps + corner protectors.

---

5. Operational Best Practices (SEA LION Protocol)

1. Pre-Export Inspection: Verify fluid drainage, battery removal, and structural integrity.
2. Cleaning: High-pressure wash with fresh water; dry completely before treatment.
3. Wax Application: Use industrial-grade applicator; ensure full coverage, especially undercarriage.
4. Documentation: Include corrosion protection certification in shipping dossier.
5. Port Handling: Coordinate with stevedores to minimize exposure during loading.

---

6. Conclusion & Recommendation

For fleet managers and construction companies exporting used excavators from China:

• RO-RO is optimal for operational, mid-sized units where speed and low handling risk are priorities.
• Bulk Cargo offers cost efficiency for non-running units destined to repair hubs.
• Flat Rack is preferred for oversized or non-standard models where containerization is necessary.

Universal Requirement: Application of industrial wax-based anti-corrosion spray is non-negotiable for all export methods to ensure equipment integrity and reduce post-import refurbishment costs.
