6. Recommendations
-
For Volume Export (≥50 units/month):
Utilize Bulk Cargo with wax spraying and unit bundling (max 5 units per lashing group). Requires port partners with heavy-lift and segregation capabilities. -
For Time-Sensitive or Premium Deliveries:
Use RO-RO with full wax protection and GPS-tracked telematics. Ideal for markets with RO-RO infrastructure (e.g., Middle East, Europe, Australia). -
For Non-Operational or Modified Units:
Flat Rack is viable only if excavators are non-drivable or have protrusions exceeding standard container limits. Must include full crating and desiccant sealing. -
Corrosion Control Mandate:
Implement wax spraying at final assembly line (China plant). Audit compliance via pre-shipment inspection (PSI) using ISO 2409 cross-cut adhesion testing.
7. Conclusion
While Bulk Cargo offers the lowest per-unit cost for large-scale exports of the Sandbox Excavator, it demands rigorous corrosion protection and handling protocols. RO-RO provides superior equipment integrity and faster turnaround, justifying its premium for high-value deployments. Flat Rack remains a niche solution for non-standard configurations. Across all methods, industrial-grade wax spraying is non-negotiable to ensure equipment readiness upon arrival.
SEA LION International recommends a hybrid logistics model: Bulk Cargo for base fleet deployment, RO-RO for urgent or high-margin contracts, with standardised anti-corrosion treatment applied universally.
