Hydraulic Breaker

GBH Series

Fully Hydraulic type Breaker

  • Top mounted Accumulator helps to accept for large range of oil flow and assist with power stroke and protect against hyd. Impact
  • High Technology of Control valve can block any damage from the high impact energy to the carrier.
  • Optimized technical design cause easy operation and long life term with low maintenance cost.
  • Fully blocked housing design is perfect for all kinds of job site and at the same time, slip fit lower bushing is easy to make field maintenance.
  • Piston and Cylinder are designed to convert the kinetic energy into hammering energy after hitting tool and transmit to tool for more rock breaking at site.
  • Fully hydraulic breaker and fully hydraulic hammer
  • Fully Hydraulic Breaker

  • Fully Hydraulic Hammer
