A hoe rams/hydraulic breaker is a powerful impact hammer fitted to an excavator for demolishing concrete structures or breaking rocks. The piston and the valve are the only two moving parts of a hydraulic breaker hammer. The piston moves up and down and hits on the tool, while the valve rotates to control the oil flow’s direction. It is the place where movement happens and where the hydraulic power is generated.
Our hydraulic breakers/peckers offering has 3 types:
the triangular/side(D) type,Top (T)type and box/silence(S)type.
Our hyraulic hoe rams are available for excavators from 4tons-80tons.
The suitable excavators include but not limit below brands:
CAT,KOMATSU,DOOSAN,DAEWOO,HYNUDAI,HITACHI,KOBELCO,VOLVO,SANY,STRONG,LINGONG,XGMA,SUNWARD,ZOOMLION,XCMG
