Subject: XCMG Forestry Mulcher Attachment (Model XM-FM350) for Heavy Excavator Platforms

---

1. APPLICATION CONTEXT & OPERATIONAL IMPERATIVE

Vegetation overgrowth and land clearing represent critical path delays in mining expansion, logistics corridor development, and large-scale construction site preparation. Traditional methods (bulldozers, manual labor) incur high fuel consumption, safety risks, and extended project timelines. The XCMG Forestry Mulcher Attachment (XM-FM350), deployed on 20-35 ton class excavators (e.g., XCMG XE215C, XE370D), delivers a precision-engineered solution for rapid, safe, and cost-effective land management.

• Mining: Clears overburden, access roads, and pit perimeters without destabilizing ground structure.
• Logistics: Prepares rail/road corridors and terminal sites in dense terrain, minimizing soil disruption.
• Construction: Efficiently manages pre-site vegetation for infrastructure projects (dams, highways, urban development), reducing pre-construction lead time by 30-45%.

• Fuel Efficiency Gain: Up to 12% improvement over previous-generation units due to HW19710 transmission’s optimized gear spacing and reduced parasitic loss.
• Emissions Compliance: Tier 4 Final / China V compliant via integrated DOC + SCR system; no DPF required for typical mowing duty cycles.

Field data from 2025 pilot fleets indicates a real-world fuel economy of 2.3 km/L (5.4 mpg) under continuous operation on graded embankments (6–12% incline).

Load Capacity & Operational Durability

The EMH-850X is engineered for dual-role performance: precision slope mowing and light-duty excavation. Key load-handling features include:

• Structural Axle Rating: Front (ZF 16.5T) and Rear (AF400 Carrier) axles rated for continuous 85% load operation in abrasive, uneven terrain.
• Dynamic Load Margin: Designed for transient overloads up to 115% of rated axle capacity (e.g., sudden side-slope shifts or debris impact) without driveline failure.
• Tire Performance: 12.00R20 R-4 tires provide superior cut resistance and heat dissipation. Dual rear configuration standard; load distribution optimized to prevent shoulder wear during offset cutting operations.
• Center of Gravity: Low-profile chassis and counterweight integration ensure <15° rollover threshold even on 30% cross-slopes.

---

Application Notes for Fleet Deployment

• Ideal Use Cases: Highway right-of-way maintenance, reservoir embankments, wind farm access roads, and post-excavation site grading.
• Maintenance Interval: 500-hour oil & filter changes; 1,000-hour transmission service (SAE 75W-90 GL-5); 2,000-hour coolant replacement.
• Telematics Ready: Optional OEM-fit telematics module supports fuel monitoring, axle load logging, and transmission health diagnostics.

---

Recommendation: The EMH-850X delivers optimal balance of mowing precision and excavation readiness, with proven fuel efficiency and axle/tire durability for high-uptime fleet operations in rugged environments.

1. Executive Summary

SEA LION International presents a comparative analysis of three primary maritime transport methods for the export of excavator mowers from manufacturing hubs in China (e.g., Qingdao, Shanghai, Nantong) to global construction markets. This report evaluates Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack (FR) container shipping in terms of cost, protection, handling efficiency, and suitability for heavy construction equipment. Additionally, we detail the application of wax-based anti-corrosion coatings as a critical protection measure during sea transit.

---

2. Equipment Profile: Excavator Mower

Best For	Operational units, low-value protection	High-volume, cost-sensitive	High-value, corrosion-sensitive units

Note: RO-RO is optimal for fleets of 5+ units; Flat Rack is preferred for machines with over-width attachments.

---

4. Corrosion Protection: Wax Spraying System

4.1. Environmental Exposure Risk

Excavator mowers are highly susceptible to marine atmospheric corrosion during ocean transport due to salt-laden air, humidity, and condensation in holds or on decks.

4.2. Recommended Protection Protocol

SEA LION International mandates automated wax-based anti-corrosion spraying prior to shipment for all export units.

Wax Application Specifications:

Parameter	Specification
Coating Type	Solvent-free, hydrophobic synthetic wax
Application Method	High-pressure spray (15–20 bar)
Coverage Areas	Undercarriage, hydraulic cylinders, joints, cutting deck, radiator fins
Film Thickness	25–35 µm (uniform layer)
Drying Time	4–6 hours at 25°C
Protection Duration	Up to 6 months (open-air exposure)
Removal Method	Biodegradable degreaser + high-pressure wash

4.3. Benefits

• Forms breathable, non-conductive barrier against saltwater ingress
• Prevents galvanic corrosion on dissimilar metals
• Compatible with rubber tracks and painted surfaces
• No residue damage to hydraulic seals

Compliance: Meets ISO 9227 (salt spray test) and ASTM D1748 (humidity resistance).

---

5. Recommended Shipping Strategy

Scenario	Recommended Method	Rationale
Exporting 10+ units, operational condition	RO-RO	Cost-effective, rapid loading, low handling damage
Single high-spec unit with attachments	Flat Rack + Wax Spray	Maximum protection, secure lashing, avoids hold moisture
Budget-constrained, inland destination	Bulk Cargo + Wax Spray	Lowest cost; wax mitigates high corrosion risk in bulk holds

---

6. Conclusion

For excavator mower exports from China, Flat Rack with wax corrosion protection offers the highest integrity for sensitive equipment. RO-RO remains the most efficient for fleet-scale deliveries, while Bulk Cargo is viable only with rigorous anti-corrosion treatment. SEA LION International implements wax spraying as standard across all export shipments to ensure equipment arrives in commission-ready condition.
