EXECUTIVE OVERVIEW: SEA LION PORTABLE EXCAVATOR PLATFORM (MODEL PX-26)

Operational Imperative: Remote and constrained worksites across mining, logistics infrastructure development, and urban construction demand equipment that combines rapid deployment, operational resilience, and transport efficiency. Traditional heavy excavators suffer critical limitations in site accessibility, relocation speed, and logistical complexity, directly impacting project timelines and OPEX. The SEA LION PX-26 Portable Excavator Platform directly addresses these constraints through engineered mobility and ruggedized design.

Core Application Value Proposition:
The PX-26 (8-12 tonne class) is engineered for high-frequency repositioning without third-party heavy haulage. Its integrated transport system—optimized for direct loading onto SEA LION-distributed SINOTRUK HOWO or XCMG truck platforms—reduces site-to-site transition time by ≥65% compared to conventional units. Key applications include:

• Mining: Rapid deployment for trenching, pit dewatering, and access road maintenance in remote open-cast operations (Africa, Siberia). Eliminates crane dependency.
• Logistics: Efficient loading/unloading in undeveloped ports, rail sidings, and temporary depots across Southeast Asia; precise material handling in confined yard spaces.
• Construction: Urban utility installation, foundation work in dense environments (e.g., Jakarta, Lagos), and rapid response for infrastructure repair where space is limited.

Regional Market Preference Drivers:
The PX-26 achieves dominant adoption in Africa, Russia, and Southeast Asia due to its alignment with region-specific operational and logistical realities. SEA LION’s 18+ years of heavy equipment export expertise ensures the solution is not merely sold, but operationally integrated.

Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared by: SEA LION International – Engineering & Logistics Division
Subject: Export Logistics Solutions for Portable Excavators from China
Target Audience: Fleet Managers & Construction Companies

---

Executive Summary

This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of portable excavators from manufacturing hubs in China (e.g., Qingdao, Shanghai, Nantong) to global construction markets. Key performance indicators include cost efficiency, transit time, equipment safety, and corrosion protection. Special attention is given to wax-based anti-corrosion treatments for protection against seawater exposure during transit.

---

1. Equipment Profile: Portable Excavator

Portable excavators exported from China typically range in operating weight from 1.5 to 8 tons. These units are designed for modular transport and rapid deployment in remote or constrained job sites. Key export models include:

Parameter	Value Range
Operating Weight	1,500 – 8,000 kg
Transport Dimensions	L: 3.2 – 5.8 m; W: 0.9 – 1.8 m; H: 2.3 – 2.8 m
Power Source	Diesel / Hybrid
Disassembly Requirement	Minimal (track folding, boom lowering)

---

2. Comparative Shipping Methods

Criterion	RO-RO Shipping	Bulk Cargo	Flat Rack Container
Loading Mechanism	Self-propelled or towed on/off vessel	Craned into open hold	Craned onto open-top flat structure
Cargo Protection	Moderate (exposed decks)	Low (exposed to ballast, humidity)	High (secured, weather cover optional)
Transit Time (Avg.)	18–25 days (Asia → Europe)	22–30 days	20–26 days
Port Infrastructure	Requires RO-RO terminal	General cargo port	Container terminal with heavy lift
Cost (per unit, USD)	$1,800 – $2,500	$1,200 – $1,800	$2,600 – $3,400
Insurance Risk Level	Medium	High	Low to Medium
Suitability for Excavators	High (if operable)	Low (risk of damage)	High (ideal for non-operable units)

---

3. Corrosion Protection: Wax Spraying Treatment

3.1 Purpose

Portable excavators are vulnerable to saltwater-induced corrosion during maritime transport, especially in tropical and high-humidity routes. Wax spraying forms a hydrophobic, sacrificial barrier on exposed metal surfaces.

3.2 Application Protocol

• Pre-Treatment: Clean all metal surfaces; remove grease, moisture, and debris.
• Wax Type: Solvent-based synthetic corrosion-inhibiting wax (e.g., lanolin-infused or petroleum-derived).
• Application Method: High-pressure spray (15–20 bar) to undercarriage, hydraulic cylinders, boom joints, and track links.
• Coverage: Minimum 25–30 µm dry film thickness.
• Drying Time: 2–4 hours at 25°C before loading.

3.3 Performance Benefits

Benefit	Impact
Salt Spray Resistance	Up to 90% reduction in surface oxidation
Protection Duration	45–60 days (sufficient for most voyages)
Post-Transit Maintenance	Simplified removal with biodegradable degreaser
Compliance	Meets ISO 9227 (salt spray test) Class 5

Note: Wax treatment is recommended for all shipping modes, but critical for Bulk Cargo and RO-RO, where exposure to sea spray is unavoidable.

---

4. Risk Assessment & Recommendations

Risk Factor	RO-RO	Bulk Cargo	Flat Rack
Mechanical Damage	Low	High	Low
Corrosion Exposure	Medium	High	Low
Theft/Vandalism	Medium	High	Low
Weather Delays (loading)	Low	High	Medium
Port Congestion Impact	Medium	High	Low

Recommended Use Cases:

• RO-RO: Best for operable units, frequent shipments, and routes with established RO-RO infrastructure (e.g., China → Middle East, Southeast Asia).
• Bulk Cargo: Only recommended for cost-sensitive, low-volume shipments with full wax protection and insurance coverage. High risk of damage.
• Flat Rack: Optimal for high-value, non-operational, or customized units. Provides superior protection and compatibility with containerized logistics chains.

---

5. Conclusion

For reliable and efficient export of portable excavators from China, Flat Rack shipping with wax corrosion protection is the recommended standard for most construction fleets. While higher in cost, it ensures maximum asset integrity and reduces post-arrival maintenance. RO-RO remains viable for functional units on compatible routes. Bulk Cargo is discouraged unless strictly budget-constrained and paired with rigorous protective measures.

SEA LION International advises implementing wax spraying as a mandatory pre-shipment procedure across all transport modes to mitigate long-term corrosion liabilities.
