Excavating equipment for excavating surfaces, in particular solid surfaces, and operating machine equipped with said excavating equipment

Equipment for excavating surfaces or solid floorings (S) such as for example made of asphalt or cement or similar solid material, in particular for excavating trenches in said surfaces or solid floorings, said equipment comprising rotatable working or excavating means supported by a main frame with a coupling of generic type for operatively coupling said equipment to the mobile arm or support of a main operating machine, and a setting frame which defines at least one contact portion substantially flat and adapted to be put into contact with a corresponding portion of the surface (S) to be worked on, wherein said main frame is housed or received in an internal space defined by said setting frame;

• characterised in that said setting frame is fixed to said main supporting frame in such a way that said setting frame can be translated with respect to said main frame on a plane perpendicular to the axis of rotation of said working or excavating means, and that said main frame and said setting frame can be rotated one with respect to the other on a main rotation axis substantially parallel to the rotation axis of said rotatable working or excavating means.
