A breaking device for soil excavation machines which consists of a crane arm design with a unit for carrying the breaking tool, including mainly a flat primary part 1 with a breaking tip 13 and a base plate 2 with devices 5, 7, 9 for connecting the tool to the crane arm design where the primary part 1 has an essentially convex external surface 3 between the breaking tip 13 and the base plate 2. The breaking tool is characterized by a breaking flange 15 which extends along the convex external surface 3 of the primary part 1 and is primarily perpendicular to the primary part, which breaking flange is designed to serve as a ground support for the breaking tool when it is moved for the breaking of a ground area that has been penetrated by the tool. <IMAGE> |
