摘要： A longitudinal beam of a track maintenance vehicle is connected at a beam exterior side—facing away from the opposite longitudinal beam—to a rail transport device provided for receiving rails. The rail transport device is displaceable by means of a displacement drive in the transverse direction of the machine relative to a machine frame within a displacement path s delimited by a transport—and a loading position.

摘要： Ballast (3) located underneath of sleepers of a track is compacted by immersion and squeezing of compacting tools (7) set in vibrations. The vibrations introduced into the ballast (3) during the compacting process are registered as a measure of the ballast compaction. Thus, it is possible to obtain a homogenously compacted track even in the event of different ballast characteristics.

摘要： A tamping machine for tamping a track has a lifting-lining unit, connected to lifting and lining drives, for shifting the track into a target position. A vibration generator, which can be set to vibrate, is disposed on the lifting-lining unit. It is thereby possible to tamp a track section in a first working pass and to lower it in a controlled way in an immediately following second working pass with constant impact of vertical load and vibration. Thereafter, the track can be traveled upon with normal speed entirely unhindered.

摘要： A welding unit for welding together two rails of a track includes two rail clamping assemblies which can be moved towards one another in a longitudinal direction of the rail along unit guides by compression cylinders. Each rail clamping assembly is equipped with clamping jaws which are displaceable in pairs in a pressing plane and each of which has a contact surface provided for application to a rail web. The clamping jaws are each constructed as clamping levers which are pivotable in the pressing plane about a lever pivot axis. The contact surface intended for application to the rail web is disposed at a first lever end spaced apart from the lever pivot axis. The two contact surfaces of each rail clamping assembly are each positioned closer to the oppositely disposed rail clamping assembly than the two lever pivot axes.

摘要： The invention relates to a tamping unit (1) for tamping sleepers (3) of a track (4), comprising oppositely positioned tamping tools (14, 17) which are connected in each case to a squeezing cylinder (9, 15) for generating a squeezing motion, wherein an eccentric drive (11) is provided for generating a vibratory motion. In this, it is provided that a first squeezing cylinder (9) is connected mechanically to the eccentric drive (11), and that a first pressure chamber (18) of the first squeezing cylinder (9) is connected hydraulically via a connecting line (22, 27) to a second pressure chamber (20) of a second squeezing cylinder (15) in order to transmit a pressure change, generated in the first pressure chamber (18) by means of the eccentric drive (11), to the second pressure chamber (20).

摘要： The invention relates to a tamping unit (1) for tamping sleepers (2) of a track (3), having a tool carrier (6) mounted on an assembly frame (12) for vertical adjustment by means of a drive (10), having pairs of two oppositely positioned tamping tools (5) which are squeezable towards one another about a respective pivot axis (4) as well as designed to be set in vibrations by a vibration drive (8). In this, it is provided that a vibration drive (11) is associated with the drive (10), the vibration drive setting the tamping tools in a vibration which is effective vertically.

摘要： A transport vehicle includes a container for receiving bulk material which is disposed on a vehicle frame and is pivoted, together with a bottom conveyor belt and a third conveyor belt, relative to the vehicle frame about a pivot axis extending in a longitudinal direction of the vehicle in order to maintain a horizontal conveying plane, relative to a transverse direction of the vehicle, for the bottom conveyor belt and the third conveyor belt, independently of a transverse inclination of the track. Thus, a problem-free bulk material transport is possible even in the event of a transverse inclination of the track. A method of loading and unloading a transport vehicle which is mobile on a track is also provided.

摘要： A bulk material loading wagon (1) for incorporation into a loading train consisting of several such wagons has a storage box (3) for storing bulk material, the storage box being open at the top and fastened to a wagon frame (2), and—associated with the storage box—a bottom conveyor belt (5) extending in the lower region of the storage box (3) and in the longitudinal direction of the wagon. The wagon frame (2) is equipped with an opening (16), arranged between two adjacent on-track undercarriages (14), for passage of a lower section—adjoining the lower deflection end (9)—of a transfer conveyor belt (8). A drive (18) is provided for displacement of the transfer conveyor belt (8) in its conveying- or longitudinal direction (4) through the opening (18) relative to the wagon frame (2).

摘要： In a method for stabilizing an earth formation exposed after removal of a track and ballast, in a first working pass in a work section following a rear crawler track with regard to a working direction, parallel to the removal of the ballast the earth formation is loosened up, aggregates are introduced, and grading takes place. In a second working pass, the earth formation to which aggregates have been added is mixed thoroughly by getting picked up by means of a clearing chain and transported onward to a discharge point located behind the rear crawler track and discharged again upon the exposed earth formation, after which, by grading and consolidating the discharged earth formation, a rehabilitation layer is formed.
