Abstract
An apparatus for lifting and laterally moving track in switch and open areas comprises a vertically and laterally movable tool carrier frame, a flanged wheel associated with each track rail and supporting the tool carrier frame for mobility on the track, a transversely adjustable gripping hook associated with each flanged wheel and mounted on the tool carrier frame for gripping engagement with the associated track rail from the outside thereof, and a gripping roller associated with each gripping hook and mounted on the tool carrier frame for grippingly subtending the rail head of the associated track rail from the outside thereof, each flanged wheel being centered between the associated gripping hook and gripping roller in the direction of track elongation.
Claims5
In a mobile machine for working on a track including two rails rastened to ties, each rail having a head and the rails having outsides facing away from each other and insides facing each other in a direction transverse to the track, the machine including a frame and an apparatus for lifting and laterally moving the track in switch areas and open track areas, the apparatus comprising
- (a) a tool carrier frame,
- (b) power drive means connecting the tool carrier frame to the machine frame for vertically and laterally moving the tool carrier frame in relation to the machine frame,
- (c) a single flanged wheel associated with each track rail and supporting the tool carrier frame for mobility on the track,
- (1) each flanged wheel having a flange engaging the inside of the associated rail head and serving as a lateral rail moving element upon lateral moving of the tool carrier frame,
- (d) a transversely adjustable gripping hook associated with each flanged wheel and mounted on the tool carrier frame for gripping engagement with the associated track rail from the outside thereof, and
- (e) a gripping roller associated with each gripping hook and mounted on the tool carrier frame for grippingly subtending the rail head of the associated track rail from the outside thereof, and for holding the associated track rail during vertical movement of the tool carrier frame,
- (1) each flanged wheel being centered between the associated gripping hook and gripping roller in the direction of track elongation.
