Executive Summary

This report evaluates three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of handheld excavators from manufacturing hubs in China (e.g., Qingdao, Ningbo, Shanghai) to global construction markets. Key performance indicators include cost efficiency, equipment protection, transit time, and corrosion mitigation. A standardized wax spraying protocol is recommended to prevent seawater-induced corrosion during ocean transit.

---

1. Equipment Profile: Handheld Excavator

Handheld excavators (mass: 80–350 kg, dimensions: 1.2–2.8 m L × 0.6–1.1 m W × 1.0–1.5 m H) are compact, diesel or electric-powered machines used in trenching, landscaping, and utility work. Due to their size and value, transport method selection significantly impacts delivery integrity and operational readiness.

---

2. Shipping Method Comparison

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo	Flat Rack Container
Loading Mechanism	Self-propelled or towed on/off	Loosely stowed in hold	Secured to open-frame container
Cargo Protection	Moderate (exposed to hold)	Low (direct exposure)	High (weatherproofing optional)
Securing Method	Wheel chocks, lashings	Lashing nets, dunnage	Lashing points, twist locks
Corrosion Risk	High (salt-laden air, moisture)	Very High	Low to Moderate (if sealed)
Transit Time	25–35 days (Asia to EU/NA)	30–40 days	28–38 days
Port Infrastructure	Requires RO-RO terminal	Standard bulk terminal	Standard container terminal

Insurance Premium	Medium	High	Low
Suitability	High (if operable)	Low (not recommended)	High (especially non-operable)

---

3. Corrosion Mitigation: Wax Spraying Protocol

Seawater exposure during transit poses a critical risk to metal components (hydraulic cylinders, undercarriage, control linkages). To ensure operational readiness upon delivery, industrial-grade wax spraying is mandated for all export units.

Wax Spraying Specifications (Per ISO 12944-6:2018)

Parameter	Specification
Wax Type	Solvent-based, hydrophobic corrosion inhibitor
Application Method	Automated spray booth (25–35 µm DFT)
Coverage Areas	Undercarriage, joints, hydraulic lines, fasteners
Drying Time	60–90 minutes at 25°C
Removal	Biodegradable citrus-based solvent on-site
Effectiveness	Prevents saltwater corrosion for up to 90 days

Note: Wax application must occur post-final QC and pre-loading. Units shipped via RO-RO and Bulk Cargo require full undercarriage coverage; Flat Rack units require partial coverage if enclosed in tarpaulin.

---

4. Method-Specific Risk Assessment

RO-RO

• Advantages: Fast loading/unloading, cost-effective for operable units, minimal handling damage.
• Disadvantages: High humidity in vehicle decks, limited weather sealing, corrosion risk without protection.
• Recommendation: Use only with wax spraying and desiccant packs in cabin (if enclosed).

Bulk Cargo

• Advantages: Lowest cost, high volume throughput.
• Disadvantages: No structural protection, high risk of impact and saltwater exposure, insurance complications.
• Recommendation: Not advised for handheld excavators. Reserved for scrap or disassembled units.

Flat Rack

• Advantages: Full lashing capability, compatible with shrink-wrapping and tarpaulin enclosures, ideal for non-operable or oversized units.
• Disadvantages: Higher cost, limited availability during peak seasons.
• Recommendation: Preferred method for high-value or non-functional units. Combine with wax spray and moisture barriers.

---

5. Operational Recommendations

1. For Fleet Managers: Prioritize Flat Rack shipping for new equipment to ensure warranty compliance and reduce rework.
2. For Construction Firms: Use RO-RO with wax protection for time-sensitive, operable units to minimize delivery latency.
3. Prohibited: Bulk cargo shipment of intact handheld excavators due to unacceptable corrosion and damage risk.
4. Compliance: All units must undergo pre-shipment wax treatment logged in the export dossier (traceable by batch).

---

6. Conclusion

Flat Rack containerization offers optimal protection for handheld excavator exports, particularly when combined with industrial wax spraying. RO-RO remains a viable mid-tier option for functional units with strict anti-corrosion protocols. Bulk cargo is unsuitable and should be excluded from logistics planning. SEA LION International mandates wax-based corrosion inhibition across all maritime shipments originating from coastal Chinese ports.
