EXECUTIVE OVERVIEW

SEA LION International presents the Towable Excavator (Model TX-85T) as a critical operational asset for high-mobility earthmoving applications across mining pre-development, logistics yard management, and constrained urban construction. Engineered for rapid deployment and minimal site footprint, the TX-85T addresses acute logistical constraints in infrastructure-limited regions while maintaining industrial-grade productivity. Its design prioritizes transport efficiency, operational resilience, and total cost of ownership (TCO) reduction—key decision factors for fleet optimization in volatile markets.

PRIMARY APPLICATIONS & OPERATIONAL ADVANTAGE

Sector	Key Application	TX-85T Advantage
Mining	Small-scale overburden removal, trenching for utility corridors	Enables rapid site setup in remote concessions; avoids high-cost mobilization of tracked units.
Logistics	Container yard material handling, stockpile management	Operates within tight intermodal spaces; towable via standard 3.5T+ trucks for multi-terminal deployment.
Construction	Urban utility installation, confined site excavation	2.1m transport width complies with narrow-road regulations; zero tail swing for trenching adjacent to structures.

PREFERRED MARKET ADOPTION: AFRICA, RUSSIA, SOUTHEAST ASIA

The TX-85T dominates in these regions due to infrastructure alignment, environmental adaptability, and TCO optimization—validated by SEA LION’s 18-year export dataset across 37 countries:

Region	Critical Demand Drivers	TX-85T Technical Response
Africa	Unpaved road networks (>65% of routes), high capital cost sensitivity, dispersed project sites	18.5 km/h road speed; 4.2m transport length (fits standard 12m flatbeds); 20% lower acquisition cost vs. mini-excavators.
Russia	Extreme cold (-40°C operational tolerance), vast remote sites, seasonal ground freeze	Arctic-grade hydraulic fluid system; reinforced undercarriage for frozen terrain; RO-RO compatible for Siberian port access.
Southeast Asia	Monsoon-season accessibility, dense urban corridors, high humidity corrosion risks	IP67-rated electrical components; 360° rotating hitch for agile maneuvering; stainless-steel linkage bushings.

SEA LION INTEGRATED SUPPORT ECOSYSTEM

As an authorized distributor for XCMG (TX-85T OEM) and SINOTRUK/SHACMAN transport solutions, SEA LION eliminates deployment barriers through:
– Pre-Deployment Refurbishment: All units undergo 127-point industrial certification, including hydraulic pressure validation and structural weld inspection.

Fuel Efficiency Performance

The Weichai WD615.68G engine is engineered for optimal combustion efficiency and low specific fuel consumption (SFC). Under standard ISO 1585 cyclic testing conditions (NEDC-based load profile), the TEC-26 achieves:

• Average Fuel Consumption: 28.5 L/100 km (8.2 mpg) when operating under mixed load (digging, travel, idling).
• Best-in-Class Efficiency: 198 g/kWh at 75% load, meeting China IV / EU Stage V emissions standards via integrated SCR + DOC + DPF aftertreatment.
• Idle Management: Auto engine shutdown (programmable, 2–10 min) reduces idle fuel waste by up to 18% in urban or stop-start operation.

Fuel economy is further enhanced by the HW19710 transmission’s wide gear spread and overdrive top gear (0.78:1), enabling lower engine RPM at highway speeds (80 km/h @ 1,680 rpm).

---

Load Capacity & Transport Compliance

The TEC-26 is designed for full compliance with national and regional road transport regulations:

• Max Legal Road Payload (GAWR-based): 1,100 kg (2,425 lbs) of additional tooling or counterweight when transported.

• Towing Compatibility: Rated for prime movers with minimum 300 hp and GVWR ≥ 20,000 kg.
• Weight Distribution: Optimized 38% front / 62% rear ensures stable handling and minimizes tire wear.

All configurations meet AASHTO and ECE R55 standards for towed equipment safety. The 12.00R20 tire specification supports continuous operation at 100 km/h under full load, with cold inflation pressure set at 850 kPa (123 psi).

---

Summary

The TEC-26 Towable Excavator combines high tractive power, regulatory compliance, and industrial durability. With the proven Weichai WD615 engine and HW19710 transmission, it delivers reliable performance across quarry, infrastructure, and municipal applications.

4. Corrosion Protection Protocol: Wax Spraying System

To mitigate seawater-induced corrosion during transit—particularly critical in RO-RO and Bulk Cargo modes—SEA LION International mandates application of industrial-grade anti-corrosion wax emulsion prior to shipment.

4.1 Wax Spraying Specifications

Parameter	Requirement
Wax Type	Solvent-free, hydrophobic microcrystalline wax
Application Method	High-pressure spray (15–20 bar)
Coverage Areas	Undercarriage, hydraulic cylinders, track links, exposed steel joints, fuel/hydraulic line fittings
Film Thickness	25–40 µm (measured via wet-film gauge)
Drying Time	4–6 hours (ambient 25°C)
Salt Spray Resistance (ASTM B117)	>500 hours (no red rust)
Removal Post-Delivery	Biodegradable citrus-based solvent or steam wash

4.2 Protection Efficacy by Shipping Mode

Shipping Mode	Corrosion Risk (Unprotected)	Risk with Wax Treatment	Notes
RO-RO	High	Moderate	Wax reduces salt adhesion on undercarriage; reapplication recommended post-delivery
Bulk Cargo	Very High	High	Limited protection due to prolonged humidity exposure in holds
Flat Rack	Moderate	Low	Tarp coverage + wax provides optimal defense; ideal for tropical/transoceanic routes

Field data: Wax-treated units show 78% lower incidence of hydraulic seal degradation and track corrosion after 21-day Pacific crossing.

---

5. Recommendations by Use Case

Client Profile	Recommended Method	Rationale
High-volume fleet (10+ units)	RO-RO	Fast loading, lower handling risk, scalable logistics
Premium excavators (> $65k/unit)	Flat Rack + Wax + Tarp	Maximum protection, traceable stowage, reduced insurance claims
Budget-sensitive, inland delivery	Bulk Cargo (with wax)	Lowest freight cost; acceptable risk if post-inspection maintenance is budgeted

---

6. Compliance & Documentation

All shipments must comply with:
– IMSBC Code (for Bulk Cargo)
– CTU Code (Cargo Transport Unit – for Flat Rack)
– IMDG Class 9 (if lithium components present)
– China Customs Export Declaration (Form EX1)
– Bill of Lading (Sea Waybill or Telex Release)

Wax application must be certified per ISO 12944-2 (Corrosion Protection of Steel Structures) and documented in the Pre-Shipment Inspection (PSI) report.

---

7. Conclusion

For towable excavator exports from China, RO-RO offers the best balance of speed and cost for standard units, while Flat Rack with wax protection is superior for high-value or climate-sensitive deliveries. Bulk Cargo remains viable only under strict wax application and post-arrival refurbishment protocols.

Wax spraying is not optional—it is a critical engineering control to preserve equipment integrity across all shipping modes.

SEA LION International enforces wax treatment as standard on all excavator shipments and provides third-party validation reports upon request.
