Abstract

Arrangement for damping vibration in a hydraulic impact hammer, the said arrangement comprising a protective casing 3 lying around the impact hammer and a spring element situated between the impact hammer 1 and the protective casing. In the arrangement the impact hammer 1 has been arranged so that it can move in relation to the casing 3 in the longitudinal direction thereof, at least by a distance equal to the length of the bit 2, and the spring element 4 has been fitted between the impact hammer 1 and the casing 3, so that it permits the said movement, the casing at a division of the material being able to bear against the material where it is divided. <IMAGE>
