Prepared Exclusively for Fleet Managers & Construction Operations Leadership
SEA LION International Trade Co., Ltd. | Heavy Equipment Mobility Solutions
EXECUTIVE OVERVIEW: TOW-BEHIND EXCAVATOR SYSTEMS
The Tow-Behind Excavator (TBE) system represents a critical advancement in mobile earthmoving capability for capital-constrained, infrastructure-variable operational environments. Unlike conventional crawler excavators requiring disassembly for transport or dedicated heavy-haul trucks, the TBE integrates a purpose-built, trailer-mounted excavator unit directly onto standardized lowboy trailers compatible with SINOTRUK, SHACMAN, and XCMG prime movers. This configuration delivers rapid site deployment, reduced mobilization costs, and enhanced fleet utilization across mining, logistics, and construction sectors.
Core Operational Value Proposition:
TBE systems eliminate the need for specialized heavy transport equipment during relocation. Excavators (15-35 ton class) remain fully assembled and operational upon arrival, slashing site setup time by 60-75% compared to disassembled units. This is paramount in projects requiring frequent equipment repositioning (e.g., linear infrastructure, open-pit mining expansion, port logistics hubs). Fuel efficiency during transit is optimized through aerodynamic trailer design and compatibility with high-efficiency truck platforms, reducing non-productive transport emissions by 22% (vs. standard flatbed transport).
Targeted Application Superiority:
| Sector | Primary Application | TBE Advantage |
| :————– | :——————————————————- | :—————————————————————————- |
| Mining | Overburden removal, pit development, access road grading | Enables rapid redeployment between pit phases; avoids costly crawler transport |
| Logistics | Material handling (stockpiles, break-bulk), site prep | 24/7 operability at remote terminals; no dependency on local heavy haulers |
| Construction | Urban infrastructure, pipeline corridors, disaster relief | Navigates constrained sites; deploys within hours of arrival at remote zones |

Note: Wax film provides temporary protection (up to 6 months) and must be removed post-delivery using biodegradable degreasers prior to commissioning.
4. Method-Specific Corrosion Risk Assessment
| Shipping Method | Exposure Risk | Recommended Protection Level | Wax Efficacy Rating (1–5) |
|---|---|---|---|
| RO-RO | High | Full wax + tarp cover | 3 |
| Bulk Cargo | Very High | Full wax + VCI packaging | 2 |
| Flat Rack | Medium | Full wax + waterproof tarp | 4 |
VCI = Vapor Corrosion Inhibitor
5. Recommendations
-
For High-Volume Fleets:
Use RO-RO for cost-effective, rapid roll-out—provided wax spraying and deck tarping are implemented. -
For Budget-Constrained Projects:
Bulk Cargo may reduce costs but requires additional investment in VCI wraps and desiccants to offset high corrosion risk. -
For Premium or Long-Distance Deliveries:
Flat Rack containers offer optimal protection and ease of inspection. Ideal when combined with wax treatment and sealed tarp systems. -
Mandatory Corrosion Control:
All units must undergo wax spraying pre-shipment, regardless of method. SEA LION International adheres to DIN 50.974 for temporary corrosion protection in transit.
6. Conclusion
While RO-RO offers operational speed and lower cost, Flat Rack shipping provides superior protection for sensitive construction equipment like tow-behind excavators. Bulk Cargo, though economical, poses unacceptably high corrosion and damage risks without extensive supplementary measures. Integrated wax-based anti-corrosion treatment is non-negotiable for all export shipments from coastal Chinese ports.
Fleet managers and procurement officers are advised to prioritize protection integrity over initial freight savings to ensure equipment readiness upon arrival and reduce field maintenance costs.
