FIELD: construction.
SUBSTANCE: device comprises a lower board 1, which by means of tension compression springs 2 (or another shock absorber) is connected to an upper board 3. On the lower surface of the lower board 1 by means of holders 4 there are air-hammer tools 5 fixed, such as serially produced perforators. They are fixed on the lower board 1 so that their sharpened tips may be arranged at different levels relative to the lower surface of this board. The device is suspended to a rope 6 of a lifting transportation device 7. The rope 6 is equipped with sensors that make it possible to measure rope tension, and the device itself is equipped with a control system designed to change rope tension, and thus to change static action force.
EFFECT: invention makes it possible to simplify design, to perform damage of various object and various materials, to increase efficiency of crushing.
