Shipping & Logistics Solutions

Industrial Specification Report 2026
Prepared for: Fleet Managers & Construction Companies
Subject: Logistics Solutions for Exporting Excavator Jack Hammers from China
Document Code: ISR-LOG-2026-041
Prepared by: SEA LION International – Senior Engineering Division
1. 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 excavator jack hammers from manufacturing hubs in China (e.g., Qingdao, Shanghai, Ningbo) to global construction markets. Key performance metrics include transit time, cost efficiency, cargo protection, and compatibility with industrial-scale deployment. Special emphasis is placed on corrosion protection via wax spraying for seawater exposure mitigation.
2. Equipment Profile: Excavator Jack Hammer
| Parameter | Specification |
|---|---|
| Weight Range | 180–650 kg/unit |
| Dimensions (L×W×H) | 1.2 m × 0.6 m × 0.8 m (avg.) |
| Material Composition | High-strength alloy steel, hydraulic connectors |
| Corrosion Sensitivity | High (exposed hydraulic ports, precision-machined surfaces) |
| Packaging | Palletized, shrink-wrapped, with protective end caps |
| Handling Requirements | Forklift or crane; no direct ground contact |
3. Shipping Method Comparison
| Criteria | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Definition | Vessels designed for wheeled/tracked equipment to be driven on/off | Loose stowage in hold; no containerization | Open-sided containers with no walls or roof; cargo secured on platform |
| Suitability | Moderate – only if jack hammer is mounted on carrier excavator | Low – high risk of damage and corrosion | High – optimal for heavy, irregularly shaped industrial tools |
| Loading/Unloading | Fast (drive-on/drive-off) | Slow (crane-dependent, manual stowage) | Moderate (crane or forklift) |
| Transit Time | 25–35 days (Asia to Europe/Middle East) | 30–40 days | 28–36 days |
| Average Cost (USD/unit) | $480–$620 | $310–$450 | $550–$720 |
| Cargo Protection | Moderate (exposed to deck elements) | Low (direct exposure to moisture, shifting) | High (with proper wrapping and wax treatment) |
| Security Risk | Medium (deck access) | High (shared hold, minimal monitoring) | Low (container-sealed, ISO-standard) |
| Stackability | Not applicable (deck-only) | Not stackable | Up to 2 units per rack (vertically secured) |
| Port Infrastructure Required | RO-RO ramps, clear maneuvering zones | Standard bulk terminal | Container gantry crane, flat storage area |
4. Corrosion Protection: Wax Spraying Protocol
Excavator jack hammers are highly susceptible to saltwater-induced corrosion during marine transit. SEA LION International recommends industrial-grade wax spraying as a mandatory pre-shipment treatment.
4.1 Wax Spraying Specifications
| Parameter | Requirement |
|---|---|
| Wax Type | Solvent-based, hydrophobic corrosion inhibitor (e.g., Cosmoline-type or equivalent) |
| Application Method | High-pressure spray (200–300 psi) |
| Coverage Areas | All exposed metal surfaces, hydraulic fittings, pivot joints, threaded connectors |
| Film Thickness | 50–75 μm (uniform layer) |
| Drying Time | Minimum 4 hours at 25°C prior to packaging |
| Removal at Destination | Biodegradable solvent wash or steam cleaning (non-abrasive) |
4.2 Efficacy
- Reduces salt spray corrosion by >90% over 45-day sea voyage
- Compatible with subsequent degreasing in maintenance bays
- Does not interfere with OEM warranties or hydraulic performance
Note: Wax treatment is strongly advised for all shipping modes, but critical for Bulk and RO-RO due to prolonged atmospheric exposure.
5. Recommended Shipping Method
Preferred Option: Flat Rack Container
– Provides structural integrity, environmental shielding (when combined with tarpaulin), and compatibility with ISO logistics chains.
– Enables full wax protection integration and secure lashing per CSC standards.
– Ideal for batch shipments of 5–20 units per container (40’ FR).
Secondary Option: RO-RO
– Only viable if jack hammers are pre-mounted on excavators.
– Requires additional waterproof tarping and desiccant use.
Not Recommended: Bulk Cargo
– Unacceptable risk of mechanical damage and corrosion.
– Lacks traceability and standardized handling.
6. Operational Recommendations
- Pre-Shipment Protocol
- Conduct visual inspection and dry-run assembly.
- Apply wax spray in climate-controlled facility.
-
Seal hydraulic ports with polymer caps.
-
In-Transit Monitoring
- Use IoT humidity/tilt sensors (optional for high-value shipments).
-
Ensure vessel route avoids prolonged tropical humidity zones.
-
Destination Handling
- Schedule unpacking within 24 hours of discharge.
- Perform immediate wax removal and functional check.
7. Conclusion
For the export of excavator jack hammers from China, Flat Rack container shipping offers the optimal balance of protection, cost, and reliability. When combined with industrial wax spraying, it mitigates seawater corrosion risks and ensures equipment readiness upon arrival. RO-RO is conditionally acceptable for integrated machinery loads, while Bulk Cargo is unsuitable for precision hydraulic tools.
Fleet managers and construction logistics planners are advised to standardize on Flat Rack + wax protection for all offshore deliveries.
