Abstract

1330681 Levelling railway track FRANZ PLASSER BAHNBAUMASCHINEN INDUSTRIEGESELLSCHAFT MBH 1 Feb 1972 [19 Feb 1971 23 Aug 1971] 4654/72 Heading B7N [Also in Division G1] A railway track levelling and tamping machine comprises a chassis 3 on which is a track lifting assembly 5 and vertically adjustable track tamping tools 4, a stretched wire 14 acting as a datum, extending between that section of the track 7 already levelled and the section to be levelled and arranged to co-operate with an electrical primary element in the form of a rotary potentiometer 20 to the axis of rotation 21 of which is fixed a fork 22 engaging the wire for pivotal movement in response to vertical movement thereof, the potentiometer being fixed to a bar 12 mounted on a measuring wheel assembly 9 running on a section of the track 7 which has been levelled, so that any change in the vertical position of the wire relative to the track 7 causes a change in resistance of the potentiometer which is applied to control a servovalve 23 acting on a piston-and-cylinder drive 24 for the hydraulic system driving the lifting assembly so that its lifting rate is controlled proportionally to bring the next section of track to the required level. An adjustable potentiometer 28 provides a signal representing the required level to a subtraction unit 27 for combination with the signal from potentiometer 20.
