FIELD: means for mechanization of electrolysis production of aluminum. SUBSTANCE: gear includes self-propelled car with vertical frame and boom mounted on it for raising and lowering and breaking fixture. Frame is mounted on one side of car and boom is put on frame and can be moved forward by means of rotary rods. Centers of rotation of the latter are displaced in upper part with regard to each other along vertical. Breaking fixture is manufactured in the form of spring vibrating hammer placed on free end of boom.
