  • Hydraulic impact hammer
    Patent number: 5718297
    Abstract: The impact hammer comprises a working piston (22) exerting impacts onto an impact surface (23). The hydraulically driven working piston (22) is reciprocatingly controlled by a control means (40,41). At the rearward end of the working cylinder (21), there is a rear chamber (50) into which the projection of the piston (51) immerses. Connected to the rear chamber (50) is a pressure gas reservoir (52) which is charged with each return stroke of the working piston and discharges with the subsequent working stroke.

  • Fluid-actuated impact hammer
    Patent number: 5520254
    Abstract: The impact hammer comprises a working piston (22) which is displaceable within a working cylinder (21) and controlled by a control means (40,41) in such a manner that it exerts impacts onto an anvil surface (23) of an adapter (24) which can be connected to the object to be advanced. When retracting the object, a return impact piston (51) exerts impacts onto the adapter (24) in opposite direction. Thereby, it is achieved that the object can be better released from the drill hole.
