Performance Analysis

Fuel Efficiency

The Weichai WD615 engine is engineered for high thermal efficiency and optimized combustion, resulting in industry-leading fuel economy under variable load cycles. In controlled field testing (ISO 9249, mixed dig-and-carry cycles):

• Average Fuel Consumption: 28–32 L/h (7.4–8.5 gal/h) under 70–80% load
• Idle Consumption: 6.5 L/h (1.7 gal/h)
• Fuel Efficiency Improvement: Up to 12% better than previous-generation engines due to high-pressure common rail (HPCR) injection and ECU-driven load matching.
• Regen Capability: Integrated DPF system with passive regeneration; minimal downtime in continuous operation.

Fuel efficiency is further enhanced by the HW19710 transmission, which allows precise gear selection to maintain optimal engine RPM in load transfer phases, reducing lugging and over-revving.

---

Load Capacity & Structural Integrity

• Maximum Digging Force (Bucket): 165 kN (37,100 lbf)
• Reach at Ground Level: 9.8 m (32.2 ft)
• Max Dumping Height: 6.9 m (22.6 ft)
• Swing Speed: 10.5 rpm (independent hydraulic circuit)
• Payload Capacity (Carry Mode): 8,200 kg (18,080 lbs) on firm, level terrain over 100 m haul
• Breakout Force (Claw Jaws): 48 kN (10,800 lbf) – adjustable via hydraulic pressure control

The structural frame is fabricated from high-tensile steel (Q345B, yield strength ≥ 345 MPa) with finite element analysis (FEA)-verified stress zones. Axle and suspension systems are rated for 5,000-hour service intervals under 90% max load conditions.

---

Operational Recommendations

• Daily Maintenance: Inspect tire tread depth (>4 mm minimum), axle seals, and transmission fluid level.
• Lubrication Cycle: HW19710 gearbox – GL-5 85W-90 oil, 10,000 km or 500-hour change interval.
• Tire Rotation: Recommended every 2,500 operating hours to ensure even wear on 12.00R20 radial tires.
• Cold Start: Engine equipped with glow plug system; operable down to -25°C (-13°F) with winter-grade fuel.

---

Conclusion

The excavator claw system with Weichai WD615 powertrain and HW19710 transmission delivers a balanced combination of high horsepower, durable load capacity, and improved fuel economy. With a total axle load rating of 18,000 kg and rugged 12.00R20 tire specification, it is suited for continuous operation in quarry, infrastructure, and heavy civil projects.

Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared for Fleet Managers & Construction Companies
Subject: Export Logistics Solutions for Excavator Claw from China
Issuing Authority: SEA LION International – Senior Engineering Division

---

1. Executive Summary

This report evaluates three primary maritime transport methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of excavator claws from manufacturing hubs in China (e.g., Xuzhou, Shandong) to global construction markets. The analysis focuses on cost-efficiency, transit reliability, equipment integrity, and corrosion protection protocols. Special attention is given to wax-based anti-corrosion treatments to mitigate saltwater exposure during ocean transit.

---

2. Product Overview: Excavator Claw

Excavator claws (also known as hydraulic demolition grapples or bucket attachments) are high-strength steel components used in heavy construction, demolition, and material handling. Due to their irregular geometry, weight distribution, and susceptibility to corrosion, specialized handling and protective measures are required during international shipment.

• Typical Weight Range: 1,200–3,500 kg
• Dimensions (L×W×H): 1.8 m × 1.2 m × 1.0 m (average)
• Material: High-tensile steel (Q345, S355)
• Corrosion Risk: High (exposed joints, pivot pins, internal cavities)

---

3. Shipping Method Comparison

Parameter	RO-RO (Roll-on/Roll-off)	Bulk Cargo	Flat Rack Container
Loading Mechanism	Self-propelled or towed	Craned into hold	Craned onto open platform
Cargo Protection	Moderate (exposed deck areas)	Low (shared hold, no cover)	High (secured, tarped)
Transit Time	25–35 days (Asia → Europe)	30–45 days	28–38 days
Port Infrastructure	Requires RO-RO terminal	Standard bulk terminal	Standard container terminal
Cost (per unit)	$1,800–$2,400	$1,200–$1,600	$2,100–$2,800
Risk of Damage	Medium (vibration, weather)	High (shifting, moisture)	Low (strapped, monitored)
Customs Clearance	Straightforward	Complex (bulk manifests)	Standard container process
Best For	Operational equipment with mobility	High-volume, low-value units	High-value, corrosion-sensitive units

---

4. Corrosion Protection: Wax Spraying Protocol

Excavator claws are vulnerable to galvanic and saltwater corrosion during extended sea voyages. SEA LION International mandates a wax-based anti-corrosion treatment prior to shipment for all export units.

4.1. Wax Spraying Specifications

Parameter	Specification
Wax Type	Solvent-based, hydrophobic rust inhibitor (e.g., Cosmoline-type or equivalent)
Application Method	High-pressure spray + brush touch-up on joints
Coverage Areas	All exposed steel, hinge pins, cavity interiors, weld zones
Film Thickness	50–75 µm (dry film)
Drying Time	4–6 hours (ambient 25°C)
Removal at Destination	Biodegradable solvent wash or steam cleaning

4.2. Performance Benefits

• Prevents saltwater ingress into pivot points
• Reduces oxidation during 30+ day transits
• Compatible with all shipping methods
• Non-toxic and compliant with IMO environmental standards

Note: Wax treatment is mandatory for Bulk and RO-RO shipments due to higher exposure. Flat Rack units may use wax + additional polywrap for enhanced protection.

---

5. Recommended Solution by Use Case

Client Profile	Recommended Method	Rationale
Fleet Managers (Multiple Units, Time-Sensitive)	RO-RO	Fast turnaround, minimal handling, suitable for mobile attachments
Construction Firms (High-Value, Single Units)	Flat Rack	Maximum protection, ideal for precision equipment
Budget-Focused Bulk Orders (>10 units)	Bulk Cargo	Lowest cost per unit; acceptable risk with wax protection

---

6. Compliance & Standards

All shipments comply with:
– IMO International Maritime Dangerous Goods (IMDG) Code (non-hazardous classification)
– CSS Code (Cargo Securing Manual) – Lashing standards for Flat Rack units
– China Export Inspection (CIQ) – Pre-shipment corrosion treatment verification

---

7. Conclusion

For excavator claw exports from China, Flat Rack shipping with wax-based anti-corrosion treatment offers the optimal balance of protection and reliability for high-value construction equipment. RO-RO is viable for time-sensitive, mobile units, while Bulk Cargo remains a cost-effective option for large-volume, lower-risk contracts—provided wax spraying is rigorously applied. SEA LION International enforces standardized wax protocols across all logistics channels to ensure equipment integrity upon delivery.
