Executive Overview: Excavator Hydraulic Hammer Attachment (Model Series: SL-HX)

---

1. EXECUTIVE OVERVIEW

The SL-HX Series Hydraulic Hammer Attachment represents a critical force multiplier for heavy equipment fleets operating in high-demand environments across mining, construction, and logistics sectors. Engineered for integration with 20–45 ton excavators (compatible with SINOTRUK, SHACMAN, and XCMG platforms), this attachment delivers optimized fragmentation efficiency, reduced operational downtime, and enhanced operator safety. Its design prioritizes ruggedness, fuel efficiency, and rapid maintenance—addressing core pain points in remote or resource-constrained sites where equipment reliability directly impacts project timelines and total cost of ownership (TCO).

Core Applications & Value Proposition

Sector	Primary Application	Operational Impact
Mining	Primary rock fragmentation, ore sizing, trenching	30% faster cycle times vs. legacy breakers; reduces secondary blasting requirements
Construction	Demolition, reinforced concrete breaking, foundation prep	25% lower fuel consumption per m³; integrated anti-vibration system cuts operator fatigue
Logistics	Material handling (e.g., frozen cargo, compacted waste)	Enables 24/7 operation in extreme conditions; modular design allows rapid redeployment

Regional Market Preference: Africa, Russia, Southeast Asia

The SL-HX Series is the preferred solution in these regions due to three convergent factors: operational resilience in harsh environments, alignment with local infrastructure constraints, and seamless integration into SEA LION’s end-to-end support ecosystem.

Fuel Efficiency Analysis

The Weichai WD615 engine, integrated with the HW19710 transmission, delivers optimized fuel efficiency through advanced high-pressure common rail (HPCR) fuel injection and intelligent load-sensing hydraulics. Under mixed operational conditions (50% idle, 30% medium load, 20% high-impact hammering), average fuel consumption is 28–32 L/h.

Fuel efficiency is further enhanced by:
– Engine ECO Mode: Reduces RPM during non-peak demand, improving fuel economy by up to 12%.
– Transmission Gear Mapping: HW19710 enables precise torque delivery, minimizing lugging and over-revving.
– Regenerative Hydraulic Circuit: Recovers energy during hammer return stroke, reducing parasitic load.

Fleet operators report an average 18% reduction in fuel cost per operating hour compared to legacy 2018 models using non-Weichai platforms.

Load Capacity & Structural Performance

The carrier frame is reinforced to handle dynamic loads generated during high-frequency hammer operation. Key load-bearing features include:

• Reinforced Boom & Arm Pivots: 40 mm high-tensile steel with dual-seal bushings.
• Counterweight Optimization: +10% rear ballast ensures stability during vertical breaking (up to 3 m depth).
• Axle Load Distribution: Rear axle rated for 11,200 kg supports breaker recoil forces without frame deflection.

The system is rated for continuous operation at 85% of maximum hydraulic pressure, allowing sustained breaking in hard rock (up to 150 MPa compressive strength). Load capacity is validated under ISO 10993-1 field testing protocols.

---

Operational Recommendations

• Daily Maintenance: Inspect chisel retention system and hydraulic hose integrity.
• Tire Pressure: Maintain at 85 psi (5.9 bar) for mixed terrain; reduce to 75 psi for soft ground to prevent rutting.
• Lubrication: Automatic central lubrication system (grease interval: 10 hrs).

This configuration ensures maximum uptime in high-intensity demolition, trenching, and quarry applications across Southeast Asian and Middle Eastern markets.

Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared for Fleet Managers & Construction Companies
Subject: Logistics Solutions for Exporting Excavator Hammer Attachments from China

---

1. Executive Summary

This report evaluates three primary maritime shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack—for the export of excavator hammer attachments from manufacturing hubs in China (e.g., Qingdao, Shanghai, Ningbo) to global construction markets. The analysis considers cargo integrity, cost efficiency, transit time, handling requirements, and corrosion protection, with a focus on long-term equipment durability under marine conditions.

A key operational recommendation includes the application of wax-based anti-corrosion spray as a protective coating to mitigate seawater-induced degradation during ocean transit.

---

2. Product Overview: Excavator Hammer Attachment

---

3. Shipping Method Comparison

Criteria	RO-RO (Roll-on/Roll-off)	Bulk Cargo	Flat Rack Container
Cargo Compatibility	Moderate – requires mobility or towability	Low – unsuitable for discrete heavy attachments	High – ideal for oversized, non-containerizable items
Loading/Unloading	Driven or towed on/off vessel	Manual/Crane handling in hold	Crane-lifted; secured on deck
Protection from Elements	Partial – exposed on vehicle deck	High risk – prone to moisture, salt spray	Exposed to weather unless wrapped
Security	Moderate – shared deck space	Low – mixed cargo in hold	High – dedicated, visible unit
Transit Time	25–35 days (Asia to Europe)	30–40 days	25–35 days
Port Infrastructure	Requires RO-RO terminal	Standard bulk terminal	Standard container terminal
Cost (USD/unit, avg.)	$680 – $850	$520 – $650	$920 – $1,150
Risk of Damage	Medium (chafing, impact)	High (shifting, moisture)	Low (if properly secured)
Best Suited For	Multiple units with mobility	Commodity-style shipments	High-value, irregularly shaped units

Note: All cost estimates based on 40ft equivalent unit (TEU) allocation or proportional space for single hammer units. Includes China port fees, B/L, and basic insurance.

---

4. Corrosion Protection: Wax Spraying Protocol

Excavator hammer attachments are highly susceptible to saltwater-induced corrosion during maritime transport, particularly at pivot points, cylinder rods, and internal hydraulic passages.

Recommended Protection: Wax-Based Anti-Corrosion Spray (VCI-Enhanced)

Feature	Specification
Product Type	Solvent-based, waxy film with Volatile Corrosion Inhibitors (VCI)
Application Method	Spray or brush pre-packing
Coverage	All exposed metal surfaces, especially joints
Film Thickness	50–75 µm (uniform coat)
Salt Spray Resistance	>500 hours (ASTM B117)
Duration of Protection	Up to 12 months
Post-Transit Removal	Biodegradable solvent or pressure wash

Benefits:

• Forms hydrophobic barrier against moisture and chloride ingress.
• Penetrates crevices and threaded areas.
• Non-toxic and compatible with elastomeric seals.
• Compliant with ISO 2230:2022 (packaging of steel goods).

Best Practice: Apply wax spray immediately after final cleaning and drying. Wrap in VCI paper and seal in breathable polywrap before crating.

---

5. Recommended Shipping Method by Use Case

Use Case	Recommended Method	Rationale
High-volume export (10+ units/month)	RO-RO	Cost-effective, faster turnarounds, efficient roll-on handling with skid trailers
Mixed heavy machinery shipment	Bulk Cargo	Only if hammer is part of larger bulk lot; high corrosion risk requires stringent wax + wrapping
High-value or custom hammer units	Flat Rack	Maximum control, visibility, and security; ideal for oversized models
Time-sensitive delivery to EU/US markets	RO-RO or Flat Rack	Avoids bulk delays; both offer scheduled liner services

---

6. Conclusion

For the export of excavator hammer attachments from China, Flat Rack offers the highest level of cargo control and protection, albeit at a premium. RO-RO provides an optimal balance of cost and efficiency for volume shipments with proper mobility. Bulk Cargo is not recommended due to high exposure to environmental degradation and handling risks.

Critical Success Factor: Implementation of industrial-grade wax spraying is mandatory across all methods to ensure long-term component integrity. SEA LION International recommends integrating corrosion protection into the factory outbound logistics protocol to reduce warranty claims and field failures.
