A torque box includes a front plate and a bottom surface. The bottom surface is coupled to the front plate such that the bottom surface is orthogonal to front plate and such that front plate extends along the bottom surface. The bottom surface defines a first raised portion configured to fit over a wheel of a railcar.

Systems and methods for monitoring an operation of a door of a public transportation vehicle are disclosed. In an embodiment, the system includes an optical sensor unit and a control unit. The optical sensor is arranged at a distance from the door and configured to record a movement of the door during an opening and/or a closing. The control unit is configured to (1) determine a position of a reference point of the door based on the recorded movement of the door, (2) determine a parameter of the movement of the door during the movement based on the determined position of the reference point, (3) determine a deviation of the parameter of the movement from a predetermined/allowed range of values of the parameter, and (4) determine an error in the operation of the door based on the determined deviation.

A chassis (1) for a rail-bound transport vehicle for transporting goods, in particular in intralogistics. The chassis (1) has at least one chassis axle (2) and at least one load-bearing roller (3) configured for rolling on a rail (4) that is rotatably supported on a pivot arm (5) about a roller rotation axis (6) and the pivot arm (5) together with the roller (3) is pivotably supported by a pivot joint (7) on the chassis axle (2). The pivot arm (5) is additionally supported by a support bearing (8) on the chassis axle (2) and the roller (3) is arranged between the pivot joint (7) and the support bearing (8).

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.

An object processing system is disclosed that includes a plurality of track sections, and a plurality of remotely actuatable carriers for controlled movement along at least portions of the plurality of track sections, wherein each of the remotely controllable carriers is adapted to support and transport an object processing bin.

The present invention relates to the field of materials science, applied to the body of a wagon for transporting loads, also including the systems of hoppers and hatches, if applicable, manufactured from composite materials that provide reduced weight in comparison to the similar conventional parts thereof manufactured from steel. The present invention also relates to the development of wagon bodies and the systems thereof such as hoppers and hatches, if applicable, which dispense with the need to use structural metal materials, contributing to the reduced weight thereof, providing lightness during operation and corrosion resistance, and to a specific design, which makes the lightweight material capable of withstanding the loads and forces to which the wagons are subjected during operation.
