4. Corrosion Protection: Wax Spraying System
Due to prolonged exposure to salt-laden maritime environments, drum cutter excavators require robust anti-corrosion treatment during transit. SEA LION International implements an industrial-grade wax-based anti-corrosion spray system as standard for all exports.
Wax Spraying Protocol:
- Product: Hydrophobic, solvent-based rust-inhibiting wax (e.g., Cosmoline VCI or equivalent)
- Application Points:
- Hydraulic cylinder rods
- Cutting head teeth and support arms
- Undercarriage and track links
- Exposed fasteners and pivot joints
- Thickness: 50–75 µm dry film
- Performance: Provides up to 6 months of salt-spray resistance (ASTM B117 compliant)
- Removal: Biodegradable citrus-based solvent; non-damaging to seals or paint
Note: Wax treatment is mandatory for all shipping modes but is especially critical for RO-RO and Bulk Cargo due to higher exposure.
5. Recommended Solution
Preferred Method: Flat Rack Container Shipping
– Offers optimal balance of protection, traceability, and handling control
– Enables full visibility during loading and inspection
– Compatible with wax-treated units without enclosure-related trapping of moisture
– Integrates with global container logistics networks
Secondary Option: RO-RO (only for self-propelled units with inbuilt corrosion protection)
Not Recommended: Bulk Cargo (high risk of mechanical and environmental damage)
6. Operational Workflow (Flat Rack Export)
- Pre-shipment inspection and dehumidification
- Application of wax-based corrosion inhibitor
- Disconnection of sensitive electronics (optional battery removal)
- Loading onto 40’ Flat Rack with engineered cradles
- Multi-point lashing (≥ 8 anchor points, 12-ton SWL straps)
- Vessel stowage on upper deck with weather cover (optional tarpaulin)
- Port discharge and customs clearance via container manifest
- Final inspection and wax removal at destination depot
7. Conclusion
For fleet managers and construction firms sourcing drum cutter excavators from China, Flat Rack container shipping combined with industrial wax-based corrosion protection represents the most reliable, secure, and traceable logistics solution. While RO-RO offers faster loading, its exposure risks and infrastructure dependencies reduce overall suitability. Bulk cargo is discouraged due to unacceptably high damage potential.
