N 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. ImpactHigh 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.
