Hydraulic Breakers

Hydraulic Breakers

JSB SERIES

Key Features

  • Anti-Blank Firing (ABF) System: Prevents the breaker from firing when there is no rock/concrete resistance, protecting the piston and tools.
  • High Impact Energy: Combines nitrogen gas and hydraulic energy for powerful strength.Simple Design: Engineered with few moving parts (mainly valve and piston) for reliability.Impact Control
  • (IC) System: Allows for effective breaking even on soft rock.Durability Enhancements: Features reinforced through-bolts and high-strength, abrasion-resistant steel construction.
  • Noise/Vibration Reduction: Silence-type models use urethane and MIC plates to suppress noise and vibration.
  • Versatile Lineup: Available in Top, Side, and Box types, covering machines from 0.7 to 50 tons. 

Benefits

  • Reduced Operating Expenses & Maintenance: Up to 30% fewer parts than competitors means lower maintenance costs.
  • Increased Uptime & Lifespan: ABF technology and robust design extend equipment life and reduce downtime.
  • Higher Productivity: High-performance motor and powerful impact ensure efficient demolition and excavation.
  • Easier Maintenance: Simple design allows for easier, low-cost maintenance and quick serviceability.
