Patent ID: 8074575

Claim:
A machine for positioning and squaring crossties of a railway track comprising: at least one wagon ( 1 ) comprising a chassis having at least two assemblies spaced along the chassis,the at least two assemblies comprising: a pair of wheels ( 10 ) supported by the chassis for traveling over rails ( 2 ) of a railway track under construction in which the crossties ( 3 ) have not yet been aligned, a main structure having an upper portion and a lower portion; and at least one pair of angled arms ( 5 ), arranged longitudinally, each angled arm having a first end actuated by a hydraulic cylinder ( 6 ) coupled to an upper portion of the main structure, a second end below the lower portion of the main structure, the angled arms being pivotally connected ( 8 ) to the main structure by a pivot at a point between the first end and the second end; a longitudinal profile ( 4 ) extending along at least a portion of a length of the wagon at a level of the crossties, coupled to the second end of each angled arm, comprising a plurality of wedges ( 7 ) spaced for pushing crossties ( 3 ) into position to be secured; wherein when the at least one wagon ( 1 ) is in an advance position, the at least one pair of angled arms ( 5 ) are raised to a position in which the wedges ( 7 ) of the longitudinal profiles ( 4 ) are disengaged from the crossties ( 3 ); wherein when the at least one wagon ( 1 ) is in a work position, the at least one pair of angled arms ( 5 ) are actuated by the hydraulic cylinders ( 6 ) to rotate about pivot, moving the longitudinal profiles at the second ends of the at least one pair of angled arms ( 5 ) closer to each other, closing the longitudinal profiles ( 4 ) in a plane of the railroad track under construction, such that the plurality of wedges ( 7 ) of the longitudinal profiles ( 4 ) push the crossties ( 3 ) laterally and longitudinally into a position in which a plurality of crossties ( 3 ) are centered along a centerline, perpendicular to the centerline and separated by a uniform distance.
