EXECUTIVE OVERVIEW

Site preparation and land-clearing operations in mining, construction, and infrastructure logistics demand equipment capable of rapid, cost-effective removal of root systems, stumps, and organic debris while minimizing soil disruption. The SEA LION SL-RR Series Root Rake Attachment addresses critical inefficiencies in these workflows, particularly in regions with challenging terrain and resource constraints. Unlike standard grading buckets or hydraulic shears, this purpose-built attachment utilizes a reinforced tine configuration to penetrate and extract subsurface obstructions with 35–40% higher productivity in dense vegetation zones, reducing machine idle time and fuel consumption by up to 22% (field data, Q4 2025).

Core Application Value

Industrial Specification Report 2026

Prepared for Fleet Managers & Construction Companies
Subject: Export Logistics Solutions for “Root Rake for Excavator” from China

---

1. Executive Summary

This report evaluates three primary maritime shipping methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack—for the export of root rakes for excavators from manufacturing hubs in China (e.g., Qingdao, Shanghai, Xiamen) to global project sites. The analysis focuses on cost efficiency, equipment protection, handling time, and corrosion prevention, with specific emphasis on saltwater exposure during transit. A standardized wax-spray anti-corrosion treatment is recommended across all methods to ensure product integrity.

4. Corrosion Protection: Wax Spraying Protocol

To mitigate seawater and humidity-induced corrosion during ocean transit, industrial-grade rust preventive wax spraying is mandatory for all units prior to shipment.

Specifications:

• Wax Type: Solvent-based, hydrophobic, salt-exclusion formula (e.g., Cosmoline VCI or equivalent)
• Application Method: Full-surface spray (minimum 20 µm thickness)
• Coverage Areas:
• All exposed steel surfaces
• Pin joints, hinge points, and undercarriage zones
• Threaded fasteners and connection interfaces
• Drying Time: 4–6 hours at 25°C prior to packing/loading
• Duration of Protection: Up to 6 months under marine conditions

Note: Wax layer must remain intact until installation. Removal via industrial degreaser is required before commissioning.

---

5. Method-Specific Recommendations

RO-RO Shipping

• Advantages: Rapid loading/unloading, reduced crane dependency, ideal for serial exports.
• Limitations: Limited to ports with RO-RO infrastructure; higher cost.
• Best Use Case: Export to Middle East, West Africa, or Southeast Asia with established RO-RO routes.

Bulk Cargo

• Advantages: Lowest cost per unit; suitable for non-time-sensitive projects.
• Limitations: High corrosion and physical damage risk; requires extensive dunnage and moisture barriers.
• Best Use Case: Large-volume tenders with flexible delivery timelines.

Flat Rack Containers (20′ or 40′)

• Advantages: Maximum protection with tarpaulin + frame enclosure; compatible with container logistics.
• Limitations: Higher handling costs; requires proper lashing (≥4-point tie-down per unit).
• Best Use Case: High-value equipment bound for North America, Europe, or island destinations.

---

6. Compliance & Documentation

All shipments must include:
– Certificate of Conformity (CoC) for steel grade and fabrication
– Material Test Reports (MTRs)
– Marine Corrosion Protection Report (wax application log)
– Packing List with unit serial numbers and dimensions
– Bill of Lading specifying Incoterms (FOB Shanghai or CIF destination recommended)

---

7. Conclusion

For optimal balance of cost, protection, and logistics efficiency:
– Choose Flat Rack for high-value or corrosion-sensitive deliveries.
– Select RO-RO for rapid deployment to compatible ports.
– Use Bulk Cargo only for budget-driven, low-risk projects with robust post-arrival refurbishment plans.

In all cases, wax-spray corrosion protection is non-negotiable to ensure operational readiness upon arrival. SEA LION International adheres to ISO 9001 and IECQ-HSPM standards in export preparation and logistics coordination.
