Hydraulic hammer GH-series ( 12 models )

GH hydraulic hammer

Advantages

  • Enviro bracket which encloses the hammer in the best possible way: reduces sound and vibration.
  • Underwater operation is easily adaptable from GH-6 and up.
  • Shock absorbing cushion rubbers (from GH-7A and up) absorbs vibration and protects integrity of excavator boom and arm.
  • Designed with sealed gas (N2) chamber – no rubber bladder accumulators.
  • Constant energy per blow: maintains high breakout force – not dependent upon blow rate.
  • Rapid and easy chisel replacement: reduces downtime to a minimum.
  • Replaceable tool bushings: prevent wear to main chisel holder body and enhance the life of the breaker.
  • Possibility to mount easily an automatic lubrication system from GH-7 and up.

Unique gas charged piston action. The Power of NPK®.
Shock absorbing Cushion Rubbers (from GH-7A): low vibration and low noise.

The Enviro brackets, utilize special heavy-duty rubber mounts to absorb shock, recoil and impulse vibration.

This unique NPK® feature minimizes machine wear and improves operator comfort for greater reliability and productivity.
