A rail transport system 10 has at least two load carrying bodies 12 which are arranged end to end. Mutually adjacent bodies 12 are coupled together by respective coupling systems 14. The rail transport system 10 further includes a plurality of axles 16 each provided at opposite ends with respective rail wheels 18 which support the bodies 12. A flexible liner 20 is supported by the bodies 12. The liner 20 is configured to span respective coupling systems 14. In this way the bodies 12 and the flexible liner 20 form a continuous load carrying structure 22. The continuous load carrying structure 22 is arranged so as to be able to pivot about an axis perpendicular to the axles 16 to facilitate unloading of cargo from the bodies 12.

A track maintenance wagon (1) for picking up and/or laying a track panel (10), comprising a wagon frame (2) supported on on-track undercarriages (4), wherein two longitudinal beams (7) of the wagon frame (2) delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel (19), and wherein crane rails (8) are arranged on the longitudinal beams (7) for a gantry crane (11) mobile in the longitudinal direction (3) of the wagon. In this, buffers (13) are arranged at two free ends (12) of the longitudinal beams (7).

The present invention relates to the technical field of engineering technology equipment and methods, in particular to a telescopic multifunctional working vehicle capable of operating in both directions and evacuating transversely, and an application method thereof. The telescopic multifunctional working vehicle comprises a fixing and lifting mechanism and a transverse moving and lifting mechanism. The working vehicle is composed of a front vehicle body and a rear vehicle body, wherein the front vehicle body is connected with the rear vehicle body through a telescopic mechanism used for realizing the contraction and the expansion between the front vehicle body and the rear vehicle body. The working vehicle is further provided with a hanging system used for hanging and moving working devices. A rail clamping device is arranged at the bottom of the working vehicle.

The invention relates to a mechanism (130) for moving stacks (21′, 22′) of sleepers (21, 22) intended to equip a railway track, the displacement mechanism (130) being intended to equip at least two successive work wagons (100, 200, 300) of a railway vehicle (1), the displacement mechanism (130) comprising guide means (140) configured to guide, along a longitudinal direction (X) of each of the wagons, a plurality of adjacent carriages (131) in pairs, the displacement mechanism (130) comprising drive means (150) for moving the carriages (131) together reciprocally between a first and a second travel position, so that each carriage (131) carries a stack (21′, 22′) of sleepers (21, 22) following a forward path (W1) from the first to the second travel position and configured to travel a return path (W2) from the second to the first travel position while being unloaded.

Apparatus and methods pertaining to moving a train rig between locations associated with corresponding different wellsites. Equipment carried by the train rig is operable in conjunction with forming wells each extending beneath a corresponding one of the wellsites. An adjustable swing arm mechanically and electrically connected to the train rig comprises a medium-voltage (MV) cable. The adjustable swing arm extends from the train rig to connect the MV cable to one of a plurality of MV electrical hubs each electrically connected to a remote MV electrical power source via, at least, MV electrical lines suspended above the wellsites. A piece of equipment carried by the train rig is energized by MV electrical power delivered via the adjustable swing arm, and then operated in conjunction with the subterranean well formation.
