Abstract

The hydraulic chipping hammer is particularly for working on concrete. The top distributor head (4), the sleeve (8) and the lower body (13) guide the bit (17) and are screwed together. A threaded portion (3) at the top end of the sleeve screws tightly into a tapped hole in the head, after which locking screws (5) are inserted in various slots (6) opposite the threads. The sleeve and the lower body are secured together by an auxiliary nut (10) mounted on the sleeve and screwed up hard onto the body. Locking screws (12) are fitted in slots opposite these threads. The slots are formed in the body interior parallel to the hammer axis.
