EXECUTIVE OVERVIEW

SEA LION International presents the standardized Excavator Brush Cutter Attachment (Model EBC-26), engineered for seamless integration with Tier 3/4f-compliant hydraulic excavators (15-50 MT operating weight). This attachment addresses critical vegetation management and land-clearing requirements across mining access corridors, logistics infrastructure corridors, and pre-construction site preparation. Its deployment directly enhances operational continuity in environments where rapid overgrowth, invasive species, and fire mitigation are persistent challenges.

The EBC-26 is not a standalone machine but a high-torque, direct-drive hydraulic attachment designed for compatibility with core platforms distributed by SEA LION, including XCMG excavators (e.g., EC550D, EC750B) and SINOTRUK/SHACMAN carrier vehicles. Field data from 2024-2025 operations confirms a 22% average reduction in land-clearing cycle times compared to conventional rotary mowers or manual clearing in dense biomass conditions (≥ 15 cm stem diameter). Key technical differentiators include:
– Dual-stage cutting system: Tungsten-carbide-tipped rotor (primary) + hydraulic shear bar (secondary) for composite vegetation (vines, saplings, brush).
– Ambient tolerance: Operational stability at -30°C (Russia) to +50°C (Africa/SE Asia) with ISO 15380-compliant hydraulic fluid.
– Carrier integration: Plug-and-play hydraulic couplings meeting ISO 1179-1 standards; no carrier ECU reprogramming required.

Regional Market Preference Rationale

The EBC-26 demonstrates superior adoption in Africa, Russia, and Southeast Asia due to its alignment with region-specific operational constraints and SEA LION’s established support infrastructure. Unlike OEM-specific attachments, the EBC-26 leverages SEA LION’s 18-year expertise in heavy equipment refurbishment and parts logistics to ensure sustained uptime in remote locations. Critical factors driving preference include:

Region	Primary Application	Key Environmental Challenge	SEA LION Solution Advantage
Africa	Mining access road maintenance; Pipeline ROW clearance	Rapid regrowth (30+ cm/week); Laterite soil abrasion	Refurbished XCMG carriers + EBC-26 kits reduce TCO by 18% vs. new imports; Localized spare parts hubs in Durban & Dar es Salaam enable <72h critical part replacement
Russia	Arctic logistics corridor prep; Permafrost zone site clearing	Sub-zero operation (-40°C); Frozen organic debris	Cold-weather hydraulic package (validated to -50°C); SINOTRUK HOWO truck integration for mobile maintenance support in remote Siberia
SE Asia	Monsoon-season infrastructure prep; Palm oil plantation maintenance	High humidity (95% RH); Fibrous root systems	Corrosion-resistant marine-grade steel housing; SHACMAN spare parts network ensures 95%+ attachment availability in Indonesia/Vietnam

Strategic Value Proposition

Fleet managers in target markets prioritize the EBC-26 due to SEA LION’s closed-loop service ecosystem:
1. Refurbishment Synergy: Attachments undergo SEA LION-certified remanufacturing (ISO 9001:2015), including rotor balancing and hydraulic seal validation, extending service life by 30% versus field-repaired units.
2. Logistics Integration: RO-RO/containerized shipping of carrier-excavator-attachment bundles from Qingdao reduces port demurrage by 25% in African/SE Asian ports.
3. Transparency Protocol: Digital maintenance logs (via SEA LION FleetSync™) provide real-time wear analytics, reducing unplanned downtime by 35% in long-term partnership contracts.

This attachment is not a cost-saving measure but a productivity assurance tool for operations where vegetation-induced delays directly impact project timelines. SEA LION’s authorization for SINOTRUK, SHACMAN, and XCMG ensures technical compliance and parts traceability—critical for audit-heavy mining and infrastructure projects. For fleet managers, the EBC-26 represents a quantifiable reduction in operational risk within the high-variability environments of emerging markets.

Fuel Efficiency Analysis

The WD615 Weichai engine is optimized for high-load intermittent operation typical in brush clearing and land development applications. Fuel efficiency is achieved through:

• High-Pressure Common Rail (HPCR) Injection: Enables precise fuel delivery, reducing consumption by up to 12% compared to legacy systems.
• Smart Load Matching: Engine ECU dynamically adjusts fuel input based on hydraulic demand, maintaining average consumption at 28–32 L/h under full brush cutting load.
• Idle Shutdown & Eco Mode: Integrated system reduces idle fuel burn by 18% over an 8-hour shift.

Average Fuel Consumption:
– Light Brush (Grass/Small Saplings): ~20 L/h
– Medium Brush (Diameter <10 cm): ~26 L/h
– Heavy Brush (Diameter 10–25 cm): ~31 L/h

This results in an estimated operational range of 10.5 hours on a full tank under mixed conditions, minimizing refueling stops on remote job sites.

---

Load Capacity & Structural Performance

The HW19710 transmission and reinforced axle system are engineered to sustain high torsional loads during prolonged brush cutting cycles:

• Transmission Torque Capacity: 1,970 N·m (peak), allowing full power delivery to all axles without slippage.
• Axle Load Distribution: Optimized weight balance ensures 58% rear / 42% front load split, enhancing traction and stability on uneven terrain.
• Tire Load Rating: Each 12.00R20 tire supports 2,120 kg at 85 psi, suitable for soft soil and rocky underfoot conditions. The R-14 tread pattern provides superior self-cleaning and lateral grip.

Maximum Payload Capacity (Tool & Debris):
– Hydraulic Tool Arm: 1,200 kg lift capacity at pivot point
– Onboard Debris Hopper (Optional): 2,000 kg rated capacity

The system maintains ISO 15818 structural integrity under continuous operation at 90% of max torque, validated through 500-hour accelerated field testing.

---

Operational Recommendations

• Maintenance Interval: 500-hour oil and filter change; 1,000-hour transmission fluid inspection.
• Tire Pressure Monitoring System (TPMS): Recommended for fleet deployment to prevent overloading and tread damage.
• Cold Climate Operation: Engine block heater compatible; fuel system rated to -25°C with winter-grade diesel.

This configuration delivers optimal balance of power, durability, and fuel economy for large-scale vegetation management in infrastructure, pipeline, and construction corridor maintenance.

Corrosion Protection Protocol: Wax Spraying Treatment

All excavator brush cutter units must undergo industrial-grade wax spraying prior to export to prevent saltwater-induced corrosion during marine transit.

Treatment Specifications:

• Wax Type: Solvent-based hydrophobic compound (e.g., Dinitrol AVA 401 or equivalent)
• Application Method: Automated spray system + manual touch-up at joints
• Coverage Areas:
• Cutting blades and counterweights
• Hydraulic cylinder rods
• Pivot pins and bearing housings
• Undercarriage frame cavities
• Film Thickness: 30–50 µm (dry)
• Curing Time: 2 hours at 25°C ambient
• Performance Standard: ASTM B117 (Salt Spray Resistance) – 500+ hours

Note: Wax film must remain intact until final site commissioning. Removal via alkaline degreaser only after installation.

---

Recommendations

Shipping Method	Recommended Use Case
RO-RO	Preferred for fleet deliveries (>10 units) to RO-RO-equipped ports; optimal balance of speed and handling safety
Bulk Cargo	Not recommended due to high risk of surface damage and corrosion; only viable under strict budget constraints with full insurance coverage
Flat Rack	Ideal for prototype units, high-value configurations, or non-standard dimensions; superior control over securing and monitoring

---

Conclusion

For reliable, large-scale export of excavator brush cutters from China, RO-RO shipping with mandatory wax spraying provides the optimal balance of cost, speed, and equipment protection. Flat Rack offers enhanced security for specialized shipments, while Bulk Cargo is discouraged due to integrity risks. SEA LION International enforces wax corrosion barriers across all outbound units as standard protocol under Project SealShield-2026.

All logistics plans must integrate pre-shipment preservation, real-time GPS tracking, and post-discharge inspection protocols to ensure operational readiness upon delivery.
