Abstract (en)
[origin: WO9730232A1] The invention relates to a concrete breaking jaw assembly with cutting claws and with a frame pivotably mounted on the excavator arm fixture. Jaws forming the concrete breaking jaw assembly are articulated to be pivotable on said frame and can be driven by means of a hydraulic piston/ cylinder unit. One cutting arm of the claws is rigidly connected to one of the jaws and the second cutting arm of the claws is provided to be rigid on the frame. The movable cutting arm (19, 19') of the claws is arranged as an additional arm on the associated jaw (8) of the concrete breaking jaw assembly (8, 9), the movable cutting arm (19, 19') having the same orientation on the fixed cutting arm (17, 17') as the jaw (8), supporting the movable cutting arm (19, 19'), in relation to the second jaw (9) opposite thereto of the concrete breaking assembly (8, 9).
