Abstract

Hydraulic breaking hammer (10) comprises (a) a machine housing (11), in which a percussion motor (15) includes a cylinder (12) and a percussion piston (17) which reciprocates in the cylinder (12) delivering blows to a breaking tool (13) supported at the front of the housing (11) carried by a support (18) attached to a connector (19) guiding the hammer. The machine housing (11) is undivided in its axial direction and interiorly in a guide passage (21) of the housing, without the support of side bolts, carries the cylinder of the percussion motor (15) fixed axially in the guide passage (21) between the an inner abutment (29) adjacent the tool-receiving portion (16) of the housing and a cover (30) attached to the rear end of the housing. The machine housing (11) merges with the carrier (18) via stiffening walls (24,25) and the carrier support (18), the intermediate walls (24,25) and the machine housing (11) are incorporated in a single one-piece metal structure.
