<p>The invention relates to an arrangement in connection with a hydraulic breaking apparatus, the arrangement comprising a housing (4) placed around a percussion hammer (1), and a changeable wearing element (6) arranged at the lower part of the housing. The wearing element (6) receives blows and forces directed at the lower part of the housing (4). The wearing element (6) is fastened in such a way that it can be detached and changed easily and rapidly, if required. Further, the structure of the breaking apparatus may also be such that when the wearing element (6) is removed, it is possible to carry out the maintenance and repair operations of the lower frame (1b) of the percussion hammer without disassembling the upper frame (1a) of the percussion hammer. <IMAGE></p> |
