Abrégé

A machine for cleaning a ballast bed has, in front of a take-up device relative to a working direction, a first signal receiver—suitable for position determination in a global navigational satellite system—for scanning an actual track position. A second signal receiver connected to the machine for scanning a new track position created by laying down the raised track onto the re-applied ballast bed is arranged downstream. Both signal receivers are associated with a control device designed to act on the drives that displace a track-lifting device relative to the machine frame.

The invention relates to a machine (1) for renewing a railway track (7) which has a ballast conveyor (20) extending in the longitudinal direction of the machine on the one hand between an upper and a lower sleeper conveying unit (12,17) and on the other hand between a ballast accommodating device and a ballast distributing arrangement (22). The ballast conveyor is equipped with a discharge end (21) which, relative to an operating direction (8), is positioned behind a device (23) for depositing new rails (24) on new sleepers (16).

Abrégé

The invention relates to a vehicle (1) that can travel along a track, said vehicle comprising a machine frame (2) on which a telescopic carrier (11) is arranged. A working platform (10) connected to height adjustment drives is arranged on the telescopic carrier. Said telescopic carrier (11) is embodied in such a way that it can rotate about a rotational axis (18) in relation to the machine frame (2) by means of a rotary device (14) which is fixed to the carrier and comprises a first rotary drive (16). A lower end (12) of the telescopic carrier (11) is fixed to the rotary device (14), at a distance from the rotational axis (18). The working platform (10) can be rotated in relation to the telescopic carrier (11), about the longitudinal axis (13) thereof, by a second rotational drive (20) arranged on an upper end (19) of the telescopic carrier (11).

Abrégé

The invention relates to a method for correcting a track bed consisting in backfilling said track (8) in such a way that it is placed in provisionally theoretical position, in subsequently controllingly lowering said track in a final theoretical position in the frame of said track stabilisation by applying a vertically acting load to which vibrations are integrated. Gravel (19) is distributed by means of a rotatable sweeping brush (14) in order to obtain a desired homogenous ballasting of the track (8). The gravel (19) arranged in the slipper intermediary area is tamped by the action of the load and vibrations along different operations after the track stabilisation and after the sweeping brush (14) passage. Said final tamping of the gravel surface makes it possible to prevent gravel projections generated by high speeds of a train.

A track maintenance machine is equipped with a soundproofing wall (10) adjustable relative to the machine frame (4) by means of drives. The soundproofing wall (10) comprises an upper and lower end (8) as well as two lateral ends (9), spaced from one another with respect to a longitudinal direction of the machine, which connect the upper to the lower end (8). The lower end (8) is formed by a flexible lower soundproofing section (11), consisting of elastic material, which has an upper end (12) spaced from the lower end (8) and connected to a rigidly formed upper soundproofing section (13).

Abrégé

A method of loading several like loading wagons (1) coupled to one another to form a loading train (15), each having a bottom conveyor belt (6) and a projecting transfer conveyor belt (10), is carried out automatically. To that end, the transporting speed of the bottom conveyor belt (6) is adjusted, in dependence upon a quantity of the discharged bulk material (16) detected by a measuring process, in such a way that the storage wagon (1) which is in the storage operational mode S is filled with a maximum loading height (h max). After a front-most dump cone (18) of the discharged bulk material (16) reaches a front end position (E), a transporting speed of the associated bottom conveyor belt (6) on the rear storage wagon (1), with regard to the transporting direction (8), adjoining with its transfer conveyor belt (10), is automatically reduced from through-transport operational mode (D) to storage operational mode (S).

Abrégé

A storage wagon (1) for bulk material (16) consists of a loading container (5), mobile on on-track undercarriages (2) and comprising a bottom conveyor belt (6) extending in the longitudinal direction of the wagon, which has a transfer conveyor belt (10) adjoining the bottom conveyor belt. The transfer conveyor belt (10) projects over a front end (12) of the wagon for transferring stored bulk material (16) onto a preceding, further storage wagon (1). Provided in the loading container (5) is a sensor device (20) for detecting the filling state, the sensor device being arranged in the rear end (19) of the loading container (5) with regard to a transporting direction (8) of the bottom conveyor belt (6). The sensor device (20) serves for detecting a maximum loading height (h) of a dump cone (18) formed by the bulk material (16) discharged by the transfer conveyor belt (10) of a storage wagon (1) following behind. The sensor device (20) is connected to a control device (23) for automatic actuation of drives (7,13) of the bottom- and transfer conveyor belt (6,10).
