A procedure for laying railway tracks on a trackbed on which sleepers (20) are located, that comprises at least the following steps: a) approach of a track laying train (30) with the stretches of rail (1) to be laid in the laying area; b) joining of the pairs of rails (1) to the consecutive rails (1) by means of tractor plates (200); c) unloading the pairs of rails (1) from the track laying train (30) onto the bed; d) squaring of the sleepers (20) by means of a squaring device; e) joining of the consecutive pairs of rails (1) by means of a joint plate (100); f) unloading of ballast in hoppers onto the bed; g) tamping of the rails (1); h) profiling of the ballast by means of a profiling device (400); i) welding of the rails (1).

The present disclosure generally relates to a rail vehicle that includes a chassis and a rail clamp assembly coupled to the chassis. The rail clamp assembly includes a fixed central member and a pair of lugs each extending outwardly from opposing sides of the fixed central member. The rail clamp assembly further includes a pair of arms respectively coupled to the lugs to thereby provide respective pivot points to permit rotation of the arms about the pivot points. A pair of gripping tool assemblies are disposed at respective lower portions of the arms and are coupled to one another via a guide rod.

A rail tool-holder cart (1) comprises a T-shaped support frame (2), a tool-holder arm, (12) rotatable about a vertical axis and tiltable between an upper position and a lower position and having a coupling interface for a tool (17, 17), a spring (19), which pushes the tool-holder arm permanently towards the upper position, so as to compensate at least one part of the weight of the tool (17, 17), as well as adjustment means (20) for adjusting the spring thrust (19).

A thread box assembly includes a framing body coupled with a moveable arm of a thread box system that positions rails of a track. The framing body includes external framing walls with an upward facing open side. The framing body includes framing supporting walls between the external walls. Supporting walls may couple the framing walls with each other. The assembly includes a closing body that can be removably coupled with the framing body. The closing body includes opposing elongated bars and opposing internal coupling walls. The elongated bars are oriented perpendicular to the coupling walls. The closing body is fastened to the framing body to define and surround a central opening of the thread box assembly through which the rails extend during installation or replacement of the track without the closing body moving relative to the framing body.

A clamp assembly may include a housing that can be positionable alongside an elongated body, one or more clamps that can be pivotally couplable with the housing, and an actuator that may pivot the one or more clamps relative to the housing. The clamps may selectively engage the elongated body to thereby restrict movement of the elongated body relative to the housing.

The invention relates to a method for unloading, transporting and installing a railway track, which does not require the rail-carrying train to be brought closer after each cycle of unloading continuous welded rail (CWR), the train remaining parked at the end of the track already laid until all the CWR has been completely unloaded. According to the invention, the method consists of: fastening two rails to a crane of an unloading wagon and moving same through windows along the wagon, facilitating the descent thereof to the track; transferring the rails to a machine for pulling and positioning which moves along, leaving the rails supported on transport elements that move along the track already laid; transferring the rails from the track already laid to a section of sleepers; and moving the rails to their final position, using sliding elements placed on the sleepers.

A maintenance vehicle has side walls for creating a work space, delimited by the same, for working personnel situated on a track. The side walls are arranged on a vehicle frame and configured to be distanced from one another in a transverse direction of the vehicle. For treatment of a track section situated within the work space, an industrial robot is arranged on the vehicle, having at least three motion axes, media couplings for energy supply as well as a tool coupling for selective connection to a track treatment tool.
