摘要
A mobile track tamping machine comprising two pivotally connected frames supported on two undercarriages spaced apart in the direction of the track for mobility on the track in an operating direction, the track consisting of two rails fastened to successive ties resting on ballast, a first one of the frames being a main frame of the machine and a second frame being a carrier frame for a ballast tamping unit arranged thereon between the two undercarriages. One undercarriage constitutes a single support and guide element for the second frame on the track, the second frame being pivotally connected to the first frame in the track direction whereby the other undercarriage constitutes a freely movable steering axle of the second frame.
