    Patent number: 5713527
    Abstract: The invention concerns an impact crusher 1 with a rotor 3 equipped with blow bars 4 and pivotably-mounted impact aprons 5, 6 arranged in the crusher housing 2, the impact aprons are positionable vis a vis the rotor by means of hydraulic cylinder-piston units 7 via piston rods 8. In a prior art impact crusher, additional mechanical devices are provided locally alongside the hydraulic retaining and positioning device 7, 9 to prevent the impact aprons 5 dropping into the tip circle circumscribed by the blow bars 4 of the rotors 3 in case of failure of the hydraulics. The invention provides additional devices connected to the corresponding hydraulically-actuatable retaining and positioning device 7, 9, using the latter's piston reds 8 to form homogeneous units 12.
