A device for increased stroke of reciprocal motion has means for displacement of material by platform fixed on chain gear, kinematically connected to mechanism of reversing motion. Mechanism of reversing motion is arranged as reversing pinion two-flow reducer with driven pinions fixed on separate shafts, installed coaxially, and chain gear is arranged as two chain circuits enclosing blocks of three sprockets, and at that in driving blocks of sprockets middle sprockets are fixed without possibility of motion, and the end ones are installed in free way on separate shafts of reducer. At that all the sprockets of driven blocks are fixed without possibility of motion on driven shaft of chain gear, and chain circuits are arranged as connected in sequence one-row and two-row chains branches of which are separated by distance equal to distance between end sprockets of each block, and one-row chain at each block is placed in such way that at de-position of driving sprocket of one circuit one-row circuit of the other contour is at the driving star.
