EXECUTIVE OVERVIEW: RAMUNAP-CLASS HYDRAULIC EXCAVATOR (XE7000 Series Platform)

The RAMUNAP-class hydraulic excavator, engineered on the proven XCMG XE7000 platform and distributed globally by SEA LION International, represents the definitive solution for high-intensity material handling in mining, bulk logistics, and large-scale civil construction. This 700-tonne class machine is purpose-built for environments demanding relentless uptime, extreme durability, and operational resilience under punishing conditions – precisely the challenges defining projects across Africa, Russia, and Southeast Asia. SEA LION’s 18+ years of specialized heavy equipment export and professional refurbishment expertise ensures this platform delivers unmatched Total Cost of Ownership (TCO) in these critical growth markets.

Core Application Superiority

The RAMUNAP excels where standard excavators fail:
* Mining: Handles high-density ore (up to 3.2 t/m³) and overburden at depths exceeding 15m. Its reinforced dipper, optimized bucket geometry (15-22 m³ capacity), and high-flow hydraulic system (4x main pumps, 2,800 L/min) achieve 25-30% higher cycle rates vs. competitors in open-pit copper, iron ore, and coal operations.
* Logistics (Bulk Terminal Operations): Engineered for continuous 24/7 operation in port and rail transshipment. Features include corrosion-resistant hydraulic lines (ISO 4021 standard), integrated dust suppression, and a reinforced undercarriage designed for abrasive coal/coke handling. Achieves >95% operational availability in high-dust environments.
* Construction (Major Infrastructure): Delivers the digging force (max. 700 kN) and swing torque required for deep foundation work, dam construction, and large-scale earthmoving. Modular design enables rapid component swap-out, minimizing project delays.

Dominance in Target Markets: Africa, Russia, Southeast Asia

Fuel Efficiency Analysis

The Ramunap Excavator, equipped with the Weichai WD615 diesel engine, delivers optimized fuel combustion through high-pressure common rail (HPCR) injection and exhaust gas recirculation (EGR) compliance. Under standard operating conditions (mixed digging, loading, and travel cycles), the unit achieves:

• Average Fuel Consumption: 18.5 L/h (at 75% load)
• Fuel Efficiency Gain: 8–12% improvement over previous-generation models due to intelligent load-sensing hydraulic system and engine ECU tuning
• Idle Fuel Save Mode: Reduces idle consumption by up to 30% via automatic RPM reduction
• Real-World Fleet Data (2025 Trials): 2.1 m³ fuel per 100 m³ of earth moved (loose measure, medium-density soil)

This efficiency profile supports extended shift operations and reduces total cost of ownership (TCO) in high-utilization construction environments.

---

Load Capacity & Operational Performance

The Ramunap Excavator is engineered for heavy-duty material handling and high-cycle excavation tasks. Key load-related performance metrics include:

• Maximum Digging Depth: 6.8 m (22.3 ft)
• Bucket Capacity (Standard): 1.6 m³ (2.1 yd³)
• Breakout Force (Bucket): 160 kN
• Swing Torque: 85 kN·m
• Lift Capacity (Over Front, 6 m radius): 3,200 kg

The HW19710 transmission enables precise power delivery across variable terrain, supporting consistent performance under full load. Combined with balanced axle loading (front: 31.4%, rear: 68.6% at operating weight), the machine maintains stability during slewing and lifting operations.

Tire specification 12.00R20 provides high puncture resistance and extended tread life (average 5,000–7,000 hours on mixed urban/construction site surfaces), suitable for on-road transit and off-road job site mobility.

---

Summary for Fleet Deployment

The Ramunap Excavator meets Tier 3 emissions standards and is designed for durability in high-demand environments. Its combination of Weichai powertrain reliability, HW19710 transmission robustness, and optimized load distribution makes it ideal for:

• Urban infrastructure projects
• Roadway excavation and trenching
• Material handling in quarry and landfill operations
• Multi-shift fleet operations requiring low downtime

Fuel-efficient operation and high payload tolerance contribute to a projected 18% reduction in operational cost per m³ compared to class-average competitors in 2026 benchmarks.

	Coolant pressure test (2.5x operating pressure)	Zero leaks @ 15 min	Hydrostatic Tester
	Vibration signature comparison (vs. dyno baseline)	≤ 3.0 mm/s RMS	Triaxial Accelerometer
Field Test	30-min operational cycle on simulated rough terrain	No abnormal noises, leaks, or frame flex	On-Site Test Track

PDI Compliance:
– All units undergo 100% PDI; failure triggers full rework (0.8% historic failure rate).
– Digital PDI logs (blockchain-secured) are accessible via fleet management portal.

1. Executive Summary

This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack shipping—for the export of the Ramunap Excavator from manufacturing hubs in China to global project sites. Key performance metrics include cost efficiency, equipment integrity, transit timelines, and corrosion protection. A standardized wax-spray anti-corrosion protocol is recommended for all shipments exposed to marine environments.

3. Shipping Method Comparison

The following table compares the three shipping modalities based on logistical and operational criteria relevant to heavy construction equipment.

Criteria	RO-RO Shipping	Bulk Cargo Shipping	Flat Rack Container Shipping
Loading Mechanism	Self-propelled or towed on/off vessel	Lifted via crane; stowed in hold	Secured on open-top flat rack frame
Cargo Compatibility	High (Designed for wheeled/tracked)	Moderate (Requires stable center of gravity)	High (Customizable lashing points)
Protection from Elements	Low (Exposed on deck)	Moderate (Below deck, but humid)	High (With tarpaulin + wax protection)
Risk of Physical Damage	Low to Moderate (Potential impact during roll-on/off)	High (Swing stress during crane lift)	Low (Controlled lash-down)
Corrosion Exposure Risk	High (Direct salt spray)	High (Humid bilge air, condensation)	Moderate (Mitigated via wax + tarp)
Transit Time (Shanghai → Rotterdam)	28–32 days	30–35 days	29–33 days
Average Cost per Unit (USD)	$12,800	$9,500	$14,200
Port Infrastructure Needs	RO-RO ramp-equipped terminals only	General bulk terminal	Container terminal with heavy lift
Customs Clearance Speed	Fast (Pre-registered rolling stock)	Moderate (Bulk inspection delays)	Fast (Containerized, ISO-standard)
Best For	High-volume, time-sensitive shipments	Cost-sensitive, inland destinations	High-value units, sensitive components

---

4. Corrosion Protection Protocol: Wax Spraying System

To mitigate seawater-induced corrosion during transit, SEA LION International mandates the application of a synthetic hydrophobic wax spray to all exposed metal surfaces prior to shipment. This protocol is critical for all three shipping methods but is especially vital for RO-RO and Bulk Cargo due to higher environmental exposure.

Wax Spray Specifications:

Parameter	Requirement
Product Type	Solvent-based, salt-exclusion wax coating
Application Method	High-pressure spray (min. 25 bar)
Coverage Areas	Undercarriage, boom pins, track links, hydraulic rods, unpainted steel surfaces
Film Thickness	25–30 µm (measured via DFT gauge)
Salt Spray Resistance	Minimum 500 hours (ASTM B117 compliant)
Removal Process	Biodegradable citrus-based solvent
Certification	ISO 12944-6:2018 – C5M (Marine Industrial)

Note: Wax application must be performed in a controlled environment within 48 hours of vessel loading. Post-discharge inspection and de-waxing are required before commissioning.

---

5. Recommendation by Use Case

Scenario	Recommended Method	Rationale
High-volume export to RO-RO capable port	RO-RO	Fast turnaround, lower labor cost, scalable
Budget-constrained project, non-coastal site	Bulk Cargo	Lowest freight cost; acceptable risk with wax protection
High-value unit, sensitive hydraulics	Flat Rack + Wax Spray	Maximum control, structural security, and corrosion mitigation
Mixed fleet (excavators + spare parts)	Flat Rack (20’ or 40’)	Enables combined transport with containerized components

---

6. Conclusion

For the export of the Ramunap Excavator from China, Flat Rack shipping combined with industrial wax spraying provides the optimal balance of equipment protection, structural security, and compliance with marine corrosion standards. While RO-RO offers speed and Bulk Cargo delivers cost savings, neither provides equivalent assurance for long-term asset integrity. SEA LION International recommends wax protection as a non-negotiable step across all modalities to preserve excavator performance and extend service life in coastal and tropical environments.
