In the demanding world of hydraulic engineering and river maintenance, standard equipment often hits its limit. When the water is deep and the silt is heavy, reach and reliability are everything. At our factory, we specialize in transforming standard excavators into high-performance dredging machines with our premium long arm modifications.
Designed specifically for harsh environments, our long arms are not just extensions; they are engineered solutions for deep dredging, slope shaping, and material handling.

Why Choose Our Long Arm Modifications?
Dredging is one of the most punishing applications for construction machinery. The combination of water, abrasive sand, and heavy clay requires equipment that can withstand extreme stress.
- Unmatched Durability: We utilize high-strength alloy steel (such as Q550 grade) to manufacture our arms. This ensures high toughness and resilience, preventing deformation even under the heavy load of wet soil and silt.
- Extended Reach & Depth: Our two-stage and three-stage long arms significantly expand your working radius. Whether you need to clear a deep riverbed or shape a high embankment, our arms allow you to reach depths of 6 to 24 meters and lengths up to 28 meters.
- Corrosion Resistance: Understanding the aquatic environment, we apply specialized anti-corrosion treatments to protect the boom and stick from rust and saltwater damage, extending the service life of the attachment.
Built for the Tough Stuff: Dredging & Silt Removal
River dredging requires more than just length; it requires stability and power. Our factory modifications are designed to maintain the hydraulic excavator's balance while maximizing digging force.
Key Application: Ideal for removing sediment, sludge, and sand from river bottoms, canals, and lakes without the need for expensive specialized dredging vessels.
Our Long Arms Excel In:
- River & Canal Dredging: Reach far out from the bank to clean deep channels.
- Slope Trimming: Perfect for shaping steep riverbanks and levees.
- Deep Foundation Pits: Capable of vertical digging for沉井 (caisson) and deep excavation projects.
Factory Direct: Quality You Can Trust
As a direct manufacturer, we don't just sell parts; we engineer performance. We understand that downtime is money. That is why our long arm kits are designed for easy installation without altering the original excavator's performance or hydraulic system.
Technical Highlights:
- Material: High-strength, wear-resistant steel plates.
- Structure: Reinforced box-section design for superior torsional resistance.
- Compatibility: Suitable for excavators ranging from 12 to 45 tons (and larger upon request).
- Safety: Designed with optimized center of gravity to prevent tipping during heavy lifting.
