Long Reach Boom and Arm — High-Performance Front-End Attachments

Long Reach Boom and Arm — High-Performance Front-End Attachments

Our Long Reach Boom and Arm assemblies are engineered to significantly extend the operational radius of hydraulic excavators. Ranging from 9 to 30 meters in total length, these specialized front-end attachments are built for deep-water dredging, slope embankment finishing, deep foundation excavation, and high-reach marine or civil demolition. Custom-tailored to support machine classes from 6 to 50 tons, each high-extension assembly utilizes high-tensile alloy steel to preserve structural stability while maximizing working reach and payload capacity.

1. Core Advantages

  • High-Tensile Steel Fabrication: Manufactured from premium Q355B, Q460, or HG785 high-strength alloy steel, allowing the boom structure to absorb elevated torsional stress and bending moments.

  • Advanced Internal Reinforcement: Features integrated internal buffer plates and heavy-duty corner gussets to distribute structural loads evenly and prevent long-term metal fatigue cracking.

  • Optimized Hydraulic Framework: Outfitted with high-pressure steel piping and dedicated auxiliary circuits for attachments, ensuring smooth flow delivery and minimal pressure drops at full extension.

  • Turnkey "Plug-and-Play" Kit: Each assembly ships as a comprehensive package including the long-reach boom, matched stick/arm, specialized bucket, bucket cylinder, hardened pins, and high-pressure interlinking hoses.

3. Global Machinery Fleet Compatibility

We engineer custom long-reach configurations to integrate directly with major international equipment lines:

  • Caterpillar (CAT): 320, 330, 336, 345, 349 Series.

  • Volvo Construction Equipment: EC210, EC240, EC290, EC360, EC480 Series.

  • Komatsu: PC200, PC300, PC400 Series.

  • SANY / XCMG / LIUGONG: Complete domestic and global export model configurations.

4. Field Technical Note for Fleet Managers

Operational Strategy for Long-Extension Operations:
• Counterweight Calibration: Extending front-end geometry drastically alters the machine's tipping center. When installing a long-reach kit, ensure the base excavator is outfitted with the correct supplementary counterweight recommended for your boom length to prevent chassis instability.
• Payload Restrictions: Long-reach attachments are designed for deep profiling, sorting, and loose material removal. They are not intended for heavy rock prying or high-impact hydraulic breaking, which can induce excessive side-torque on the extended arm pins.
