Claim:
A tank for transport railway trucks for railroad rehabilitation machines, comprising: a holding structure ( 5 ) mainly extending along a predetermined direction (X); at least one first conveyor ( 8 ) mounted within the holding structure ( 5 ) to transport incoherent material along the predetermined direction (X) internally of the holding structure ( 5 ), between an inlet region ( 9 ) to said holding structure ( 5 ) and an outlet region ( 10 ) from said holding structure ( 5 ); means for laying the holding structure ( 5 ) on a railway truck ( 3 ) in a removable manner; and means ( 23 ) for hooking the holding structure ( 5 ) to the railway truck ( 3 ) in a removable manner, wherein the tank further comprises auxiliary thrust means ( 21 ) for the incoherent material, which auxiliary means ( 21 ) is movable along the transport direction (X) and, at least during its moving forward from the inlet region ( 9 ) to the outlet region ( 10 ), extends over a rest surface ( 12 ) of said first conveyor ( 8 ), to interfere with the incoherent material, and wherein the auxiliary thrust means ( 21 ) comprises a plurality of lugs extending transversely of the transport direction (X) at least during moving forward from the inlet region ( 9 ) to the outlet region ( 10 ), said lugs being movable in a reciprocating manner along the transport direction (X); and said lugs during the reverse motion from the outlet region ( 10 ) to the inlet region ( 9 ) lying in side by side relationship with the rest surface ( 12 ) not to interfere with the incoherent material.
