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.

A maintenance vehicle has a vehicle frame, supported on on-track undercarriages, on which are arranged two side walls extending in a longitudinal direction of the vehicle and adjustable with respect to one another and relative to the vehicle frame in a transverse direction of the vehicle by way of drives. The vehicle is equipped with at least one load crane which is displaceable on a crane guide that extends in the transverse direction of the vehicle. The crane guide, designed to be elongatable in the transverse direction of the vehicle, is connected at each end to a side wall.

A fish plate clamp for unloading rails 1. The fish plate clamp includes a support element (11, 12) with a first piece (11) and a second piece (12) each one located on a face of the rail (1). Each piece of the support element (11, 12) includes an internal mortise (13) in the area of the web (3) of the rail (1). The fish plate clamp also includes a gripping element (14) located in an internal mortise (13) of the support element (11, 12). The internal mortises (13) have an inclined surface (15) in a manner that, when the gripping element (14) moves along the length of the inclined surface (15) of the internal mortise (13) in the direction of the pull of the rail (1), the gripping element (14) latches onto the web (3) of the rail (1).

The rail-lifting hook is a J shaped lifting hook that is specifically configured to replace chains and slings when lifting a railway track rail. The railway track rail is configured to receive the entire railway track rail within the interior surface of the hook structure of the J shaped lifting hook. The rail-lifting hook is formed as a single unit from high strength steel.

A track disassembling device comprises a protective housing, a cleaning component and a lifting pin, wherein the protective housing comprises a shell and a supporting plate, the cleaning component is movably sleeved with the protective housing and comprises a cleaning disc, a positioning rod, a connecting disc, a limit disc, a first spring and a first movable block, and the lifting pin is propped against the cleaning disc. A crank structure is formed by fitting with a connecting rod, a locating pin, a second movable block and other structures through the rotation of a turntable, and the second movable block can make reciprocating movement under the limit of the supporting plate to the second movable block; the second movable block making reciprocating movement can exert pressure on the first fixing component to form an impact when the electric telescopic rod extends, achieving separation from the axis pin.
