1. OPERATIONAL CONTEXT & VALUE PROPOSITION

The RH14 excavator addresses critical productivity and durability challenges in high-intensity mining, bulk material logistics, and infrastructure construction. Designed for 10,000+ hour operational cycles in abrasive environments, its core value lies in reducing total cost of ownership (TCO) by 18-22% versus regional benchmarks through:
– Fuel-Optimized Powertrain: 168 kW Tier 3-compliant engine with adaptive load sensing (ALS) hydraulics, achieving 12-15% lower fuel consumption in repetitive digging cycles (e.g., quarry loading, trenching).
– Modular Undercarriage System: Triple-sealed rollers/bushings and hardened track links extend service intervals by 30% in high-abrasion applications (e.g., iron ore mining, river dredging).
– Operator-Centric Cab: ROPS/FOPS Level II certified with climate control, reducing fatigue during 12-hour shifts in extreme ambient conditions (±50°C operational range).

3. SEA LION INTEGRATED SUPPORT ADVANTAGE

While the RH14 platform delivers inherent ruggedness, SEA LION’s 18-year export infrastructure transforms reliability into guaranteed operational continuity:
– Refurbishment Standard: Used RH14 units undergo 210-point inspection with OEM-certified component replacement (e.g., pumps, main control valves), restoring 92%+ of original performance.
– Parts Availability: 98.7% stock accuracy for critical wear items (buckets, teeth, track assemblies) across regional hubs; 72-hour delivery guarantee for Tier-1 components.
– Logistics Optimization: RO-RO vessel coordination for bulk fleet deployments; containerized crate design reduces transit damage by 37% (verified 2025 field data).

---

4. CONCLUSION: SUSTAINABLE PRODUCTIVITY

The RH14 is not merely an excavator but a TCO-optimized asset validated across Africa’s dust storms, Russia’s deep freeze, and Southeast Asia’s humidity extremes. SEA LION’s technical partnership model—combining XCMG engineering with industrial-grade refurbishment, parts assurance, and cold-chain logistics—eliminates the downtime risks that plague competitor equipment in volatile markets. For fleet managers prioritizing predictable output and lifecycle cost control, the RH14 ecosystem represents the lowest-risk productivity solution in 2026.

Fuel Efficiency Performance

The RH14 excavator is optimized for fuel economy through the integration of the Weichai WD615 engine, known for its combustion efficiency and low specific fuel consumption. The engine operates at a BSFC (Brake Specific Fuel Consumption) of 198 g/kWh under standard load conditions.

• Average Fuel Consumption:
• Idle: 4.2 L/h
• Medium Load (60% capacity): 18.5 L/h
• High Load (85–100% capacity): 26.0 L/h

Fuel efficiency is further enhanced by the HW19710 transmission, which enables precise gear selection and minimizes power loss. The engine’s ECU is calibrated for load-sensing hydraulics, reducing unnecessary fuel burn during light operations.

Estimated Operational Cost Savings:
Compared to industry peers, the RH14 achieves 8–12% lower fuel consumption over a 200-hour monthly operating cycle under mixed-load conditions.

---

Load Capacity and Structural Integrity

The RH14 is engineered for maximum payload reliability and structural endurance:

• Maximum Digging Force (Stick): 132 kN
• Maximum Crowd Force (Bucket): 118 kN
• Static Ground Pressure: 58 kPa (with standard track configuration)

The reinforced undercarriage and high-tensile steel boom/arm assembly support sustained operation with abrasive materials and high-density soils. The balanced axle load distribution (front: 38%, rear: 62%) ensures stability during lifting and slewing operations, reducing tire wear and improving traction.

Tire Performance Notes:
The 12.00R20 radial tires provide excellent heat dissipation and puncture resistance, suitable for prolonged use on rocky or uneven terrain. Load index rating supports up to 2,600 kg per tire at 5 bar inflation pressure, aligning with the rear axle’s peak loading.

---

Conclusion

The RH14 excavator delivers a compelling combination of power, efficiency, and durability for fleet operators in the construction and mining sectors. With the proven Weichai WD615 engine, HW19710 transmission, and robust load-handling capabilities, it is positioned as a reliable asset for high-uptime operations. Fuel efficiency improvements and optimized weight distribution further enhance TCO (Total Cost of Ownership) for large-scale deployment.

1. Executive Summary

This report evaluates three primary shipping methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of the rh14 excavator from manufacturing hubs in China to global project sites. Key performance indicators include cost efficiency, transit time, equipment protection, and corrosion resistance. Special emphasis is placed on wax-based anti-corrosion treatments to mitigate seawater exposure during ocean transit.

4. Corrosion Protection: Wax Spraying System

4.1. Technical Rationale

Seawater exposure during transit induces accelerated corrosion on steel undercarriages, hydraulic fittings, and electrical junctions. The rh14 excavator’s extended oceanic exposure (up to 40 days) necessitates proactive protection.

4.2. Wax-Based Anti-Corrosion Treatment (SEA LION Spec: WAX-CORR 2026)

Parameter	Specification
Product Type	Solvent-based, penetrating wax
Application Method	Pressurized spray (15–20 bar)
Target Zones	Undercarriage, track links, boom pins, radiator fins
Film Thickness	25–30 µm (dry)
Salt Spray Resistance	1,000+ hours (ASTM B117)
Removal Process	Biodegradable citrus-based solvent
Application Time	45 minutes per unit

Note: Wax treatment is mandatory for all export units. RO-RO and Bulk Cargo shipments require full undercarriage coverage; Flat Rack units receive supplementary wax on exposed joints.

---

5. Recommended Shipping Protocol

Shipping Mode	Wax Application Required	Securing Method	Monitoring During Transit
RO-RO	Full undercarriage + joints	Chocks, lashing straps (4-point)	Visual inspection at port departure
Bulk Cargo	Full equipment + engine bay	Wooden cribbing, wire ropes	Humidity loggers (shared hold)
Flat Rack	Standard wax + boom seals	Twist locks, lashing bridges (6-point)	GPS + shock/vibration telemetry

---

6. Conclusion & Recommendations

• For urgent, high-volume deployments: RO-RO offers rapid turnaround but demands rigorous wax protection and port compatibility.
• For budget-constrained projects with flexible timelines: Bulk Cargo is economical but carries the highest risk of corrosion and handling damage.
• For premium protection and traceability: Flat Rack is optimal despite higher cost, especially when combined with wax spraying and real-time monitoring.

SEA LION Recommendation:
For global export of the rh14 excavator, Flat Rack shipping with WAX-CORR 2026 treatment provides the highest equipment integrity assurance. This method minimizes post-delivery rework, reduces warranty claims, and aligns with ISO 12944-2:2019 standards for marine corrosion protection.
