<p>A tool for splitting rocks that simplifies greatly the operations of shaping or splitting rocks or blocks of concrete, though being usable by unskilled personnel,without special equipment and/or special materials, that imply significant investments, precautions or safety requisites. This is achieved with a mechanical tool for splitting rocks that commonly comprises two guides (1), preferably shaped like cylindrical sectors, to be introduced in a hole drilled in the block to be split, and a wedge (2), to be hammered to drive it between the guides for divaricating them, provided with a shaped tang (3) adapted to be coupled to the mandrel of a pneumatic hammer.</p> |
