What is a jackhammer on an excavator called?
Hydraulic Hammers/Breakers

Breakers are driven by a hydraulic piston that exerts pressure on the head of the attachment to provide a powerful and consistent thrust into the obstruction. In simplest terms, it's just a really really big jackhammer.

SIDE BREAKER TYPE
● Adopting innovative design concept,strong impactan the power system,the system is high efficiency.energy loss
reduced to minimum and impact energy is verylarge
● Precise and energy-saving nitrogen cylinder structure streamlines,so that the breaker is more energy efficient,can
providefirst_class powerfulimpactenergy.
● Special durable piston can increase the piston stroke.increase theimpactpower.
● Special damping system can reduce recoil,eliminate mechanical elasticity. protect the main body.
● Pistan adopt special heat treatment,piston and cylinder precision is turther improved,teducing the resistance and
improving efficiency.
● Flaw adjustable device applied,can effectively regulate the power source flow,which can flexibly adjust the
required impact and stiking frequency
● High-quality & high-pressute accumuiator can reduce the impact,increase the striking energy.make the working
ability more intelligent
● High-quality materials with special precision technology ensures thatthe striking power,explosive power,stability
wil be better,

Suitable:
Used for mining, demolition, construction, quarry etc;
It can be mounted on all common hydraulic excavator as
well as mini excavator and other carrier like skid steer loader
backhoe loader, crane, telescopic handler, wheel loader and
other machinery.

Features:
l.Cylinder & valves: prevents scuffing with precision finishing
treatment;
2.Piston: every piston tolerance is machined perfectly accord
ing to each cylinder;
3.Chisel: 42CrMo, exceptional performance and reliability.
