Four Sets Excavator Long Arm Kit for Doosan excavator

Introduction to Long Reach Excavator Booms

Excavator long reach booms are specialized attachments that extend the digging range of standard excavators by 40-100%. These heavy-duty extensions are engineered for demanding applications where standard arms lack sufficient reach or digging depth.

Our CE-certified long reach booms are manufactured using:
✔ High-tensile Q690D steel (16-25mm thickness)
✔ Robotic welding technology for consistent quality
✔ Advanced stress analysis for optimal load distribution

Key Advantages of Our Long Reach Booms

1. Unmatched Productivity

• 30% faster cycle times in dredging applications
• 40% greater reach than OEM arms
• 20% lower fuel consumption per cubic yard

Example: A 24m arm moved 800m³/day vs 550m³ with standard arm at Chilean copper mine

2. Superior Durability

• 12,000+ hour lifespan (vs 8,000h for standard booms)
• Centralized lubrication points reduce maintenance
• Reinforced pivot joints withstand heavy loads

3. Custom Engineering

• Machine-specific designs for perfect fit
• Bucket quick-change systems available
• Corrosion-resistant options for marine work
