<p>A railcar for renovating railways including: an operating unit (10) provided with equipment for removing the old tracks (15) and with supporting elements (17,18,19) for advancing on the old sleepers (Tv) stripped of their tracks (15), and, in sequence: first means (41) for gripping the old sleepers, capable of executing controlled cyclic oscillatory and vertical movements to grip said old sleepers, for removing them from their original seat and depositing them on a removal conveyor (31); a rotary operating element (51), capable of executing controlled cyclic oscillatory and vertical movements for the prearrangement of each seat (S1) stripped of its related old sleeper (Tv); at least one strike element (61), susceptible to longitudinal motion with respect to the frame of the operating unit and subject to fluidodynamic control means (66,67) for the compaction of the new laying plane (Pp) in each prepared seat (S3); second grip means (71), capable of executing controlled cyclic oscillatory and vertical movements for taking the new sleepers (Tn) from a feeder conveyor (32) and for controllably resting them on the laying plane (Pp) of each regenerated and compacted seat; and strike elements (61) also capable of executing controlled longitudinal and vertical movements, for the packing of rubble for filling and final securing, fed into the spaces (90,91) comprised between the walls of the regenerated seat and the new laid sleeper.</p> |
