摘要： A welding assembly (1) for welding two rails (2) of a track includes two rail clamping units (5) movable towards one another in an assembly longitudinal direction (4). A power rail (10) provided for power transmission is configured as an assembly guide (3), extending in an assembly longitudinal direction (4), which is spaced from displacement drives (11) and connects both rail clamping units (5) to one another. The power rail (10) is equipped with a cooling device and displaceable in the assembly longitudinal direction (4) relative to the rail clamping unit (5) equipped with the power rail contacts (8).

摘要： A welding apparatus for welding rails of a track comprises two welding units which are movable relative to one another and which are each equipped with clamping jaws at a lower end. The clamping jaws are configured for resting on a web of the rail. Each welding unit is connected to a supporting device which can move relative to the welding unit and which is provided for resting on the track during operation.

摘要： A tamping unit for tamping a track has tamping tines which are designed for immersion into a ballast bed and which can be set in vibrations by a vibration drive. The vibration drive includes a housing in which a shaft including an eccentric is arranged for rotation about a shaft axis. A transmission element for transmitting a vibratory motion is mounted on the eccentric. The eccentric is connected to the shaft in a rotation-locked and radially displaceable manner, wherein the position of the eccentric relative to the shaft is adjustable in radial direction by an adjustment device. Thus, while retaining the advantages of an eccentric drive, it is possible to adjust vibration parameters during operation.

摘要： Two squeezing drives, each connected via a joint to a tamping tine of a tamping unit, are connected to one another—unchangeably with regard to their position relative one another—to form a drive unit. The latter has a sliding bearing, situated between the two joints, which is freely movable in vertical direction in a bearing guide connected to the tine carrier.

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： A welding unit for connecting two rails of a track by flash-butt welding, includes clamping jaws having contact surfaces intended for application to a rail web and a power jaw for current transmission having a contact surface for application to the rail web. The power jaw is displaceable relative to the clamping jaw in a pressing direction leading to contact with the rail. In an inoperative position spaced from the rail web, the power jaw, due to the pressure of a pressure spring, is situated in a forward end position with regard to the pressing direction, in which the contact surface of the power jaw projects beyond the contact surface of the clamping jaw.

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： For correction of a track position in connection with ballast cleaning, after cleaned ballast has been returned to a a track, the actual position of the latter is measured while determining actual position data. Parallel to that, fixed point correction values are determined by a sighting trolley following behind. The actual position data and the fixed point correction values are transmitted to the tamping machine, following behind, and are used for determining correction values for a desired track position to be created by tamping.

摘要： A track maintenance machine for stabilizing a ballast bed of a track after a tamping operation, includes a machine frame mobile on on-track undercarriages and a stabilizing unit which has rollers for gripping a track grid and a vibration generator for actuating the track grid with a vibration. A clearing device is disposed at both longitudinal sides of the track maintenance machine in front of the stabilizing unit with regard to a working direction. Each respective clearing device includes a clearing tool which can be lowered into the ballast bed to remove ballast from a respective sleeper-end region. Thus, preconditions are created by using the stabilizing unit to achieve an increased lowering of the track grid as compared to a normal stabilizing procedure. A method for operating a track maintenance machine is also provided.
