FIELD: construction.
SUBSTANCE: in the proposed device ballast is cut from sleeper-to-sleeper space and end of sleepers with a working element. The working element is a frame with holes in vertical and horizontal plane, combs and feed switch with traction fingers. Combs are hingedly fixed on the frame axis. Combs make reciprocal movements with the help of a drive. The drive is arranged outside the rail track.
EFFECT: simplified design and possibility to perform works without closure of a span.
