1. Executive Overview: Power Wheeled Excavator Platform

SEA LION International presents the Power Wheeled Excavator (PWE) series as a critical productivity asset for demanding operations across Mining, Logistics Yard Management, and Infrastructure Construction. Distinct from conventional tracked excavators, the PWE platform integrates high-mobility wheeled chassis with robust hydraulic excavation systems, delivering optimized performance for applications requiring rapid site repositioning, reduced ground disturbance, and versatile material handling on prepared surfaces.

This platform excels in scenarios demanding:
* High-Mobility Material Handling: Efficient loading/unloading in logistics hubs (ports, rail yards, distribution centers) and stockpile management in mining overburden removal.
* Urban & Confined Space Construction: Precise trenching, foundation work, and utility installation where minimal site footprint and quick relocation between urban job sites are paramount.
* Light-to-Medium Mining Support: Drilling support, pit dewatering, access road maintenance, and secondary破碎 operations where track systems incur excessive wear or transport costs.

2. Regional Market Preference: Africa, Russia, Southeast Asia

The PWE series demonstrates significant operational and economic advantages in the target regions, driven by specific environmental, infrastructural, and operational constraints. SEA LION’s 18+ years of heavy equipment export experience, coupled with our authorized distribution network (SINOTRUK, SHACMAN, XCMG) and integrated refurbishment/logistics services, directly addresses these regional pain points.

Regional Market	Primary Drivers for PWE Preference	SEA LION Value Proposition
Africa	Limited paved infrastructure; need for rapid relocation between remote sites; high ambient temps; requirement for extreme durability & simplified maintenance; cost sensitivity.	Refurbished Fleet Quality: Rigorously rebuilt units meeting OEM specs. Parts Availability: Strategic regional spares hubs (Johannesburg, Lagos) for XCMG/SINOTRUK components. RO-RO Logistics: Direct vessel access to major ports minimizing inland transit damage.
Russia	Severe cold-weather operation (-40°C); vast distances between sites; frozen ground conditions; need for reliable mobility on snow/ice; compliance with GOST standards.	Cold-Start Systems: Integrated engine pre-heaters & hydraulic fluid management. GOST-Certified Refurb: Full compliance validation. Containerized Logistics: Year-round delivery via rail/sea corridors to Siberian/Far East sites.
Southeast Asia	High humidity/tropical conditions; mixed terrain (urban/construction zones); frequent monsoon impacts; demand for multi-functionality (excavation, lifting, grading).	Corrosion-Resistant Coatings: Enhanced undercarriage & hydraulic protection. Multi-Attachment Support: Streamlined integration for augers, breakers, grapples via SHACMAN/XCMG interfaces. Containerized Parts Supply: Rapid replenishment via major hubs (Singapore, Jakarta).

3. Core Advantages Driving Adoption

• Operational Efficiency: 20-30% faster cycle times between work zones compared to tracked equivalents, directly increasing billable hours in logistics and construction.
• Reduced Operational Costs: Lower fuel consumption (15-25% vs. comparable tracked units), minimized tire wear on paved surfaces, and avoidance of track replacement costs.
• Enhanced Utilization: Dual functionality as an excavator and a mobile material handler (with appropriate attachments) maximizes asset ROI for fleet managers.
• SEA LION Integration: Seamless compatibility with our global logistics network (RO-RO/Container) ensures timely deployment. Our professional refurbishment program guarantees reliability, while direct access to OEM spare parts (SINOTRUK, SHACMAN, XCMG) drastically reduces downtime – a critical factor in remote operations.

4. Conclusion

The Power Wheeled Excavator represents a strategic solution for fleet optimization in the dynamic markets of Africa, Russia, and Southeast Asia. Its inherent mobility, versatility, and operational cost profile align precisely with the infrastructure realities and economic demands of these regions. SEA LION International, leveraging its deep technical expertise, authorized OEM partnerships, and vertically integrated service model (refurbishment, parts, logistics), provides not just equipment, but a verified, sustainable operational asset. We enable fleet managers and construction enterprises to achieve higher productivity, lower TCO, and enhanced project resilience through a foundation of quality, transparency, and long-term partnership.

Corrosion Protection: Wax Spraying Protocol

Due to prolonged exposure to marine atmospheres and potential saltwater ingress during transit, wax-based anti-corrosion treatment is strongly recommended for all power wheel excavators prior to shipment.

Wax Spraying Specifications:

Parameter	Requirement
Coating Type	Solvent-based anti-corrosion wax (e.g., Cosmoline-type)
Application Method	High-pressure spray (minimum 30 psi)
Coverage Areas	Undercarriage, hydraulic cylinders, track links, exposed welds, chassis cavities
Film Thickness	75 – 100 µm (uniform layer)
Drying Time	24 hours (pre-shipment)
Removal Process	Biodegradable solvent wash post-delivery
Compliance Standard	ISO 9227 (Salt Spray Test certified)

Note: Wax treatment reduces salt-induced corrosion by up to 85% during 30–45 day sea voyages. Mandatory for Bulk and RO-RO shipments; recommended for Flat Rack when destination is high-humidity or coastal.

---

Recommendations by Use Case

Scenario	Recommended Method	Rationale
High-volume fleet delivery (50+ units)	RO-RO	Fast turnaround, minimal handling damage, operational upon arrival
Disassembled or non-functional units	Bulk Cargo	Lower cost; suitable for reassembly at destination
Premium units to tropical/coastal regions	Flat Rack + Wax Spray	Maximum protection, controlled environment, reduced corrosion risk
Time-sensitive project deployment	RO-RO	Direct loading, minimal port delays

---

Risk Mitigation Strategy

1. Pre-shipment Inspection: Verify hydraulic seals, track tension, and battery isolation.
2. Wax Application Audit: Third-party verification of spray coverage and thickness.
3. Lashing & Securing: Use ISO-certified chains (min. 4-point tie-down for Flat Rack).
4. Environmental Monitoring: Desiccant packs in control cabs; humidity tags in packaging.

---

Conclusion

For optimal balance of cost, protection, and delivery speed, Flat Rack with wax-based corrosion protection is the preferred solution for high-value power wheel excavators destined for corrosive environments. RO-RO remains efficient for functional fleets to RO-RO-capable ports, while Bulk Cargo is viable only for cost-driven, non-critical shipments with post-arrival refurbishment plans.

All export consignments should integrate wax spraying as a standard anti-corrosion measure, regardless of shipping mode.
