Why Your Project Needs a Specialized Long Boom

Standard excavator arms fail in demanding conditions. Our Q690D steel booms with Ningbo connectors deliver:
→ 40% longer lifespan in abrasive environments (river dredging, mining)
→ 20% greater reach than OEM arms (18-30m configurations)
→ Anti-corrosion protection for marine applications

Top Applications:
✔ Port dredging ✔ River cleaning ✔ Deep foundation work ✔ Mining overburden removal

3-Step Customization Process

1. Share Your Requirements:

   • Excavator model (e.g., CAT320D, Hitachi ZX225)
   • Digging depth & material type (sand, rock, etc.)
   • Project photos/videos (optional but recommended)

2. Receive Technical Proposal:
   → 3D CAD drawings of your boom
   → Material certification (Q355B/Q690D options)
   → Cycle life analysis for your workload

3. Fast Production & Delivery:
