  • Patent number: 11198450
    Abstract: A cable car system has at least two cable car stations and at least one carrying cable between the stations. A cable car vehicle is moved by a hauling cable between the car stations. The travelling positions of the vehicle along the travelling route are determined by a measuring device and transmitted to a control unit and processed and stored in same. A signal is input into the control unit by an input device located on a cable car support such that maintenance or assembly works and similar are carried out on this cable car support. When a cable car vehicle approaches the cable car support, the drive for moving the at least one cable car vehicle is controlled by the control unit such that the cable car vehicle is moved at a significantly reduced speed in relation to the operating speed, or is stopped at the cable car support.

  • Patent number: 11180893
    Abstract: A rail fastening device comprises a clip (10) having a base (11) and a nose (12) for engaging a rail flange (F). The base (11) comprises circular aperture (14) in which a circular cam (13) is rotatably mounted, the cam (13) being provided with an eccentric aperture (24) for receiving a ground anchor (25), the cam aperture (24) being radially offset from the rotational centre of the cam (13) to define a cam lobe (15). The cam (13) may comprise a ramped circumferential shoulder (18) to engage a complementary shoulder (21) inside the base aperture (14) such that any rotation of the cam (13) under the applied load of the rail causes the cam (13) to move axially of the base aperture (14) thereby tightening the engagement of the anchor (25) on the cam (13) and preventing movement of the clip (10). The degree of rotation of the cam (13) may be limited so that it can only turn in the tightening direction under load.

  • Patent number: 11180170
    Abstract: A system, method and assembly for detecting the operational status of one or more discharge gates on one or more railcars. The system and method monitor parameters that include whether the discharge gate is open or closed, whether the railcar is in motion or not, and whether the railcar is in a location where it is acceptable for the discharge gate to be open. Sensors carry out the monitoring, and the information obtained by monitoring the parameters are used to determine if a notification event has taken place and if so, a notification of such event can be transmitted to a remote receiver. A change in the status of any one of the monitored parameters can trigger the determination of whether a notification event has occurred.

  • Patent number: 11174598
    Abstract: A method for the correction of vertical position error of a track by a track tamping machine and a dynamic track stabilizer. Starting from a registered actual position, an over-lift value is prescribed for a treated track location with which the track is lifted into a preliminary over-lift track position and tamped. The track is subsequently lowered by dynamic stabilization into a resulting final track position. In this, a smoothed actual position course is formed from a course of the actual track position, wherein an over-lift value is prescribed for the treated track location in dependence of the course of the actual track position with regard to the smoothed actual position course. In this way, only short-wave track faults are treated with an over-lift value.
