Hammers

GH-Series hydraulic hammers: more power and less noise

Advantages

• Enviro bracket which encloses the hammer in the best possible way: reduces sound and vibration.
• Underwater operation is easily adaptable from GH-4 and up.
• Shock absorbing cushion rubbers (from GH-7 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.
