EXECUTIVE OVERVIEW

Material handling inefficiencies in bulk earthmoving operations—particularly in site preparation, overburden removal, and stockpile management—represent a critical cost driver across mining, logistics, and construction sectors. Conventional bucket systems exhibit suboptimal performance in fragmented rock, mixed soil, and debris-laden environments, resulting in 15–22% productivity loss due to material spillage, excessive re-handling, and accelerated wear. SEA LION’s engineered excavator rake attachment directly addresses these constraints through validated mechanical design and material science, delivering measurable operational ROI in high-demand applications.

This specification details the SL-ERX Series Rake, a purpose-built attachment optimized for integration with SINOTRUK, SHACMAN, and XCMG hydraulic excavator platforms (20–50 ton class). Its adoption is driven by three core industrial imperatives:
1. Enhanced Material Capture Efficiency: Patented tine geometry (60° penetration angle, 45mm hardened alloy steel) reduces bounce-back in rocky terrain by 34% (per ISO 10263-5 field trials), increasing effective payload per cycle.
2. Reduced Total Cost of Ownership (TCO): Modular wear components (replaceable tips, side plates) lower maintenance downtime by 27% versus monobloc designs. Compatible with SEA LION’s global spare parts network, ensuring <72-hour critical part availability.
3. Fleet Compatibility & Refurbishment Synergy: Designed to leverage SEA LION’s 18-year expertise in heavy equipment lifecycle management. Rakes undergo the same rigorous refurbishment protocols as parent carrier fleets, extending service life by 40% while maintaining OEM hydraulic compatibility.

Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared for: Fleet Managers & Construction Companies
Subject: Logistics Solutions for Exporting Excavator Rake from China
Issuing Authority: SEA LION International – Engineering & Logistics Division
Report Date: January 2026

---

1. Executive Summary

This report evaluates three primary maritime shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack containers—for the export of excavator rakes from manufacturing hubs in China (e.g., Qingdao, Shanghai, Ningbo) to global construction markets. The analysis focuses on cost efficiency, equipment protection, transit integrity, and corrosion mitigation, with specific emphasis on wax-based anti-corrosion treatments for seawater exposure.

---

2. Product Overview: Excavator Rake

Excavator rakes are heavy-duty attachments used in earthmoving, demolition, and land clearing. Constructed primarily from high-tensile steel (e.g., Hardox 450/500), they are susceptible to saltwater-induced corrosion during ocean transit. Dimensions and weight vary by model, but typical units range from 2.5 to 4.5 meters in length and 1,200 to 3,800 kg in mass.

---

3. Shipping Method Comparison

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo	Flat Rack Container
Suitability for Excavator Rakes	High (if self-propelled or towable)	Low to Moderate (not recommended for individual units)	High (optimal for oversized, non-wheeled attachments)
Loading Mechanism	Driven or towed onto vessel	Loosely stowed in hold	Secured onto open-sided flat rack, crane-loaded
Protection Level	Moderate (exposed decks; risk of salt spray)	Low (direct exposure, shifting risk)	High (custom lashings, optional tarpaulin cover)
Cargo Security	Medium (shared deck space)	Low (commingling with other bulk)	High (dedicated unit, sealed documentation)
Transit Time (China → Europe/USA)	28–35 days	30–40 days	26–34 days
Average Cost per Unit (USD)	$1,800–$2,400	$1,200–$1,600 (but high risk)	$2,600–$3,200
Port Infrastructure Requirements	RO-RO-capable terminals	Bulk-handling facilities	Standard container cranes & flat rack availability
Risk of Damage	Medium (deck movement, weather exposure)	High (impact, moisture, poor stowage)	Low (controlled lashing, monitoring)
Customs & Documentation	Moderate	Complex (bulk manifests)	Streamlined (containerized, ISPM-15 compliant)

Note: Bulk Cargo is generally unsuitable for excavator rakes unless shipped as part of a large-scale project with dedicated hold space and protective bundling.

4. Corrosion Protection: Wax Spraying Protocol

4.1 Rationale

Marine environments expose ferrous components to chloride-laden aerosols, accelerating oxidation. Unprotected steel surfaces may exhibit surface rust within 72 hours of exposure.

4.2 Recommended Solution: Industrial Wax Spray (VCI-Enhanced)

A solvent-based, vapor-corrosion-inhibiting (VCI) wax coating is applied pre-shipment to all exposed metal surfaces, including teeth, pivot joints, and mounting brackets.

Application Specifications:

Parameter	Specification
Product Type	Hydrophobic, VCI-infused microcrystalline wax
Film Thickness	25–40 µm (uniform coverage)
Application Method	Electrostatic spray + brush touch-up at joints
Drying Time	30–45 minutes (25°C ambient)
Protection Duration	Up to 6 months (unwashed)
Removal Process	Biodegradable alkaline degreaser (pH 9.5–10.5)
Compliance	ISO 9227 (salt spray test), ASTM D1748 (humidity resistance)

4.3 Integration by Shipping Method

• RO-RO: Full wax application mandatory; deck exposure necessitates complete coverage.
• Bulk Cargo: Not advised; wax protection insufficient against prolonged moisture contact and physical abrasion.
• Flat Rack: Optimal platform for wax-treated units; tarpaulin covering further enhances protection.

---

5. Recommended Shipping Strategy

Priority	Recommended Method	Rationale
High Volume, Time-Sensitive	Flat Rack Container	Superior protection, traceability, and customs efficiency
Cost-Sensitive, Mobile Units	RO-RO	Viable if rakes are transportable; requires strict wax protocol
Not Recommended	Bulk Cargo	High risk of damage and corrosion; unsuitable for discrete equipment

---

6. Operational Recommendations

1. Pre-Shipment Protocol:
2. Conduct surface degreasing prior to wax application.

3. Apply wax 24–48 hours before loading to ensure full cure.

4. Lashing & Securing (Flat Rack):

5. Use minimum 5,000 kg WLL (Working Load Limit) chains with tensioners.

6. Anchor points must engage structural nodes, not hydraulic or wear components.

7. Documentation:

8. Include wax application certificate and material safety data sheet (MSDS) in shipping dossier.

9. Label containers with “Corrosion-Protected – Do Not Power-Wash” tags.

10. Port Handling:

11. Coordinate with destination terminals for immediate inland transport to minimize coastal exposure.

---

7. Conclusion

For reliable, corrosion-resistant export of excavator rakes from China, Flat Rack containerization with industrial wax spraying presents the optimal balance of protection, compliance, and operational control. RO-RO remains a secondary option for mobile configurations, provided wax treatment is rigorously applied. Bulk cargo is not advised due to unacceptable risk profiles.

SEA LION International recommends integrating wax-based preservation into standard export SOPs across all maritime logistics channels.
