FIELD: construction.SUBSTANCE: device may be installed on an upper edge of a structure and may damage the structure by fragments, starting from the top. On the frame there are at least three cross beams, of which at least one of the cross beams is made with the possibility of length variation. The device differs by the fact the frame may be adapted to various diameters or dimensions of the structures due to the fact that the cross beam of the varied length is mounted as capable of displacement in the specified frame or on it.EFFECT: possibility to use a device for demolition of structures with different dimensions.35 cl, 13 dwg |
