Overview: Excavator Rake Attachment for Global Markets

INDUSTRIAL SPECIFICATION REPORT 2026: EXECUTIVE OVERVIEW

Product: SEA LION Series XR Heavy-Duty Excavator Rake Attachment (Models XR-1200 to XR-3500)
Target Applications: Mining Overburden Clearance, Logistics Yard Material Handling, Construction Site Grading & Debris Management

Core Value Proposition

The SEA LION XR Series rake attachment is engineered to significantly enhance material handling efficiency and versatility for excavators (15-50 ton class) operating in high-abrasion, high-volume environments. Unlike standard bucket configurations, the XR Series utilizes a patented dual-plane tine geometry and hardened alloy steel (Hardox 450/500 base structure, AR400 tines) to optimize penetration, material retention, and structural integrity during demanding tasks such as:
Mining: Efficient clearing of loose overburden, coal, and fragmented ore; stockpile reclamation.
Logistics: Rapid sorting, grading, and cleanup of bulk materials (aggregate, biomass, recyclables) in port yards and depots.
Construction:* Precision grading of rough terrain, topsoil separation, and demolition debris management.

Field data demonstrates a 22-35% reduction in cycle times for material sorting and stockpile management compared to conventional buckets, directly translating to lower fuel consumption per ton moved and increased daily operational throughput. The attachment’s modular design ensures compatibility with major OEM excavators distributed by SEA LION International (XCMG, SINOTRUK, SHACMAN), minimizing integration complexity for fleet managers.

Regional Market Preference Drivers

Fuel Efficiency Analysis

The Weichai WD615 engine is calibrated for optimal combustion efficiency under variable load cycles typical in excavation and grading operations. When paired with the HW19710 transmission’s wide gear spread, the system maintains engine operation within the peak torque band during rake dragging and material displacement, reducing fuel waste.

• Average Fuel Consumption:
• Light Load (raking loose debris): 18–21 L/h
• Medium Load (brush/rock sorting): 24–27 L/h
• Heavy Load (compacted soil/root systems): 30–33 L/h

Fuel efficiency is further enhanced through:
– Engine Auto-Idle Function: Reduces rpm after 5 seconds of inactivity.
– Load-Sensing Hydraulics: Minimizes parasitic power loss.
– Thermal Management System: Maintains optimal coolant and oil temps, improving combustion consistency.

Over a 1,000-hour operating cycle, this configuration demonstrates a 9–12% improvement in fuel economy compared to legacy Tier II platforms with similar output.

---

Load Capacity & Operational Performance

The carrier unit is engineered to handle high-inertia forces generated during aggressive raking and pile manipulation. Key load performance metrics:

• Maximum Raking Pull Force: 168 kN (37,800 lbf) at drawbar
• Payload Capacity (Material Carry Mode): 5.2 metric tons (on flat terrain, low center of gravity)
• Slope Operation Limit: Up to 30% grade with full load (equipped with traction control)

The 12.00R20 tires provide:
– High load-bearing capability (152 = 3,750 kg per tire)
– Deep tread for off-road traction
– Resistance to puncture and sidewall damage in rocky or debris-filled environments

The HW19710 transmission ensures smooth power delivery across all gears, enabling controlled starts under load and reducing driveline shock. Axle load distribution is optimized to prevent overloading on soft ground, maintaining ground pressure below 0.75 MPa.

---

Conclusion

The excavator rake attachment system with Weichai WD615 engine and HW19710 transmission delivers industrial-grade reliability, superior load handling, and measurable fuel savings. Designed for high-uptime operations, this configuration meets the demands of large-scale site preparation and material management for construction fleets.

Corrosion Protection Protocol: Wax Spraying System

To ensure integrity during marine transit, all excavator rake attachments must undergo a standardized anti-corrosion treatment prior to shipment:

Wax-Based Protection Specifications

Parameter	Requirement
Coating Type	Solvent-based anti-corrosion wax spray
Application Method	Pressurized spray (even coat, 50–70 µm)
Coverage Areas	All exposed steel surfaces, pivot joints, bolt threads
Drying Time	2 hours at 25°C (ambient)
Salt Spray Resistance	Minimum 500 hrs (ASTM B117 test)
Removal Method	Biodegradable degreaser + high-pressure wash
Certification	ISO 12944-6:2018 compliant

Note: Wax application must occur within 24 hours of final surface preparation and prior to crating or loading. Re-inspection required if delay exceeds 72 hours.

---

Recommendations by Use Case

Scenario	Recommended Method	Rationale
High-volume export to EU	RO-RO	Faster turnaround, lower handling cost per unit, compatible with port infrastructure
Budget-sensitive project in Africa	Bulk Cargo	Lowest freight cost; acceptable if wax protection and desiccant use are enforced
High-value rake for offshore project	Flat Rack	Maximum protection, secure lashings, ease of customs inspection
Mixed equipment shipment (rakes + tools)	Flat Rack	Modular loading; compatibility with containerized logistics chain

---

Risk Mitigation Guidelines

• RO-RO: Ensure non-operational status; battery disconnected; secure all moving parts.
• Bulk Cargo: Mandate wooden skid base and corner protectors; use VCI (Vapor Corrosion Inhibitor) sachets inside sealed joints.
• Flat Rack: Lashing with ≥4 tensioned straps (2” width, 5,000 kg SWL); tarpaulin cover with UV resistance (280 g/m² min).

---

Conclusion

For excavator rake attachments exported from China, Flat Rack shipping offers the highest level of protection and is recommended for high-value or corrosion-sensitive deployments. RO-RO is optimal for volume efficiency and faster deployment cycles. Bulk Cargo remains a cost-effective option only when paired with rigorous anti-corrosion protocols, including mandatory wax spraying.

All shipments must integrate the specified wax-based corrosion protection system to ensure equipment readiness upon arrival. SEA LION International enforces compliance with ISO 9001 and IACS standards across all transport modes.
