A mobile track working machine comprises a machine frame and an apparatus for lifting and laterally moving the track in a switch section, which apparatus comprises a vertically and laterally movable tool carrier frame, power-actuated drives linking the tool carrier frame to the machine frame for vertically and laterally moving the tool carrier frame with respect to the machine frame, a pair of flanged wheels supporting the tool carrier frame for mobility on the track, a respective one of the flanged wheels being associated with each track rail and serving as track lining element, and a respective rail gripping device mounted on the tool carrier frame for engagement with the field side of the associated rail and including a first rail gripping hook transversely and vertically adjustable for engagement with the associated rail and a rail gripping member of a different type for subtending the rail head at the field side of the associated rail. A further transversely and vertically adjustable rail gripping hook is mounted on the tool carrier frame, associated with each rail and spaced from the first rail gripping hook in the operating direction, and independent drives are connected to each rail gripping hook for independent vertical and lateral adjustment thereof. |
