Custom Excavator Long Reach Arms & Booms (10T – 100T)

 

Expand your excavator's operational envelope for river dredging, deep foundation piling, canal maintenance, and high slope forming. We manufacture custom 2-piece and 3-piece long reach excavator booms (10m to 32m reach) engineered specifically for your base machine tonnage and hydraulic capacity.

  • High-Tensile Steel Fabrication: Built using Q355B, Q690D, and wear-resistant plates with internal baffle plates for maximum torsional rigidity under heavy breakout forces.
  • Turnkey Complete Kit: Each package includes the boom, stick/arm, bucket cylinder, hardened 40Cr pivot pins, phosphor bronze bushings, and factory-routed hydraulic hard lines.
  • Exact Brand & Model Fit: Precision-bored pin connections compatible with Caterpillar, Komatsu, Hitachi, Volvo, Kobelco, Sany, Doosan, and other major brands.
  • Safety & Stability Guaranteed: 100% ultrasonic weld inspection (NDT) with custom counterweight matching to maintain machine balance and prevent tipping.
