Rock Hammer Excavator Attachment High Intensity Big Rigidity Strong Capacity
Hydraulic breaker is applicable to road construction, house demolition subway and tunnel construction in cities,it has the advantage of high quality material,high intensity,long life and strong bearing capacity.
Rock drill includes the spare parts as below:air-check valve,back head,inward valve,outward valve,cylinder,piston,front head and chisel
suitable for this areas.
The pressure oil provided by the excavator or the pumping station of the loader will supply the power to breaker hammer then the hydraulic rock breaker can crush stone and rocks more effectively during construction efficiency.
It protect the environment required by various countries in the world because of innovative low-noise design,this mechanism can effectively regulate the flow from excavators or power sources, so that the required impact force and frequency can be adjusted according to the rock conditions.
