-
For Fleet Managers (1–10 units):
Use RO-RO shipping with full wax protection. Offers fastest turnaround, lowest handling risk, and predictable logistics. -
For Construction Firms (10–50 units):
Bulk cargo is optimal for cost efficiency. Requires centralized port unloading and immediate post-arrival de-waxing and inspection. -
For Oversized or Custom RTE Models:
Flat Rack containers are the only viable option. Mandate full wax encapsulation and weatherproof tarping. Monitor via IoT moisture sensors. -
Universal Requirement:
All shipments must include onboard desiccant units and post-discharge inspection checklist for corrosion and fluid integrity.
7. Conclusion
The selection of export logistics for rubber tire excavators from China must balance cost, transit reliability, and long-term equipment integrity. While RO-RO offers operational simplicity and Bulk Cargo delivers economy of scale, Flat Rack remains necessary for non-standard units. In all cases, industrial-grade wax spraying is non-negotiable for corrosion prevention.
