Construction and Main Parts

Korean Hydraulic Hammer
  • Cover Bolt
    The Cover and the Case of the main body are tightly fixed with Cover bolts. | Korean hydraulic hammer
  • Cover
    The Gas charging valve is built in and the inside is charged with N2-gas. | Korean hydraulic hammer
  • Valve
    The Cylindrical control valve is built in the Liner and controls piston reciprocation. | Korean hydraulic hammer
  • Piston
    Kinetic energy of the piston is converted into hammering energy after hitting the Tool. The hammering energy transmitted to the Tool breaks rocks.
  • Housing
    Optimized housing design by 3D modeling and lower side is reinforced by high abrasion-resistant steel. Applying Round box design which has a better durability.
  • Tool
    The specially heat-treated Tool is directly applied to break rocks. It is used as moil point, wedge point and flat Tool according to the application(optional).
