マ。 It is equipped with a ram fitted so as to be able to move up and down within the hammer housing, and an anvil fitted into the lower end of the hammer housing, and a gas communication path or an opening to the outside that communicates the gas chambers formed above and below the ram. In a hydraulic hammer configured to drive a pile by striking an anvil with a ram, a piston ring that can slide against the inner periphery of the hammer housing is fitted to the outer periphery of the lower part of the ram and the outer periphery of the anvil, and the piston ring is fitted to the ram. The hydraulic hammer is characterized in that the gas chamber formed below the ram becomes a sealed space when the piston comes below the lower end of the gas communication path or the lower end of the opening to the outside.
