ABSTRACT:
A hydraulic hammer having an improved buffer assembly is provided. The hydraulic hammer includes a housing, a top cover plate connected to the upper portion of the housing, a hammer assembly installed in the housing, and a buffer assembly for supporting the hammer assembly, installed between the top cover plate and the hammer assembly, in which the buffer assembly includes a top buffer contacting the upper portion of the hammer assembly and formed of an elastic material for absorbing impact, and a sliding plate is disposed between the top buffer and the top cover plate. The hydraulic hammer reduces the repeated banding stress applied to the hammer assembly.
