A system is provided that includes a self-propelled platform that can traverse a first rail of a first vehicle and a first rail of a second vehicle, the first rail of the first vehicle and the first rail of the second vehicle separated in spaced relation. The self-propelled platform has a wheel assembly that can engage the first rail of the first vehicle and the first rail of the second vehicle. The wheel assembly may include at least one guide extending away from the self-propelled platform and having a size and shape to engage a first rail of the first vehicle or the first rail of the second vehicle while a portion of the self-propelled platform remains on the first rail of the first vehicle and the first rail of the second vehicle, to guide the wheel assembly onto the first rail of the first vehicle or the first rail of the second vehicle.

An auto guide vehicle (20) that conveys a cart (10), wherein the auto guide vehicle (20) is provided with: a fluid pressure cylinder (22) that is able to be extended and retracted vertically, and that applies an upward pressing force to the floor surface of the cart (10); a fluid pressure supply device (70) that supplies a fluid to the fluid pressure cylinder (22); pressure regulating means (50) that regulates the fluid pressure of the fluid supplied from the fluid pressure supply device (70) to the fluid pressure cylinder (22); a control board (40) that outputs a fluid pressure command value to the pressure regulating means (50); and a pressure sensor (100) that detects the fluid pressure of the fluid supplied to the fluid pressure cylinder (22); wherein the control board (40) computes derivatives of the fluid pressure detected by the pressure sensor (100), estimates a timing at which the cart begins to leave the ground based on a pattern of the computed derivatives, and computes the command value by multiplying a coefficient less than one by the fluid pressure detected by the pressure sensor (100) at the estimated timing.

A processing system has at least one multi-axis robot for performing track work. The processing system includes an enclosure in the form of a container for receiving the at least one multi-axis robot and at least one displacement device for displacing the at least one multi-axis robot between a transport position inside the enclosure and a working position outside the enclosure. This enables track work to be carried out in a simple, flexible, safe and reliable manner.

A railway wagon comprising a load carrier, and front and rear bogies, wherein each bogie comprises a platform, which is rotatably mounted. The load carrier is releasably connected to, and laterally displaceable in relation to, the platforms. The load carrier has a front end and a rear end and is provided, at each end, with a connection portion, and two support devices, which are laterally spaced, and which support the load carrier in a position where it is laterally displaced in relation to the platform. The support devices are vertically operable between an idle position and a support position, in which the support devices abut against the ground. Further, the railway wagon comprises a displacement device for laterally displacing the load carrier.

The invention relates to a railway wagon comprising a load carrier (7) and front and rear bogies (8), each of the bogies being provided with railway track wheels and being electrically, hydraulically and/or pneumatically connected to the load carrier by means of one or more electric cables, hydraulic and/or pneumatic tubings (5). The load carrier is releasably connected to the respective bogies, and in a released state laterally displaceable in relation to the respective bogies by means of a displacement device. The load carrier has a front and a rear end and is at each end provided with a support device and a ramp (13), wherein the support device is adapted to support the load carrier on the ground in a position where it is displaced in relation to the bogie, whereas the ramp is along an inner edge pivotally connected to the end of the load carrier. The ramp is provided with a suspension device on the underside of the ramp including a guide arrangement (1) extending transverse in relation to a longitudinal axis of the load carrier, along which guide arrangement a slider (2) is displaceably movable, wherein the slider is provided with a holder (3) for holding of the one or more cables and/or tubings while allowing transverse movement of the cables and/or tubings together with the slider and holder along the guide arrangement.

A railway wagon for semitrailers and the like may include a first bogie, a second bogie, and a carrying section therebetween. An elongated channel configured to receive conduits for air, hydraulics and/or electronics may extend between the two bogies. The media channel may be lowered in a mechanical way when the carrying section is turned out to a loading/unloading position.

A vessel for transporting a material that is solid or semi-solid at ambient temperature, includes a body having an interior surface comprising textured metal, and a superoleophobic coating on the interior surface for inhibiting the material from adhering to the interior surface, the superoleophobic coating including a nanotextured coating disposed on the textured metal and functionalized with a fluorinated compound. The superoleophobic coating facilitates flow of the material along the interior surface.
