Patent number: 12385190Abstract: A tamping assembly for tamping sleepers of a track has a tamping unit with tamping tools. The tamping tools are located opposite one another, are mounted on a height-adjustable tool support, and, by way of drives, can be caused to vibrate and can be fed relative to each other. Each tamping tool includes a pivot lever, which can be rotated about a feed axis, and an inner and an outer tamping pick retainer. Each tamping pick retainer can be laterally pivoted relative to the pivot lever. The outer tamping pick retainer can be pivoted about a first pivot axis and the inner tamping pick retainer can be pivoted about a second pivot axis. The second pivot axis is arranged at an offset to the first pivot axis. Thus, it is no longer necessary to adjacently arrange elements for pivoting the tamping pick retainers.Type: GrantFiled: September 10, 2020Date of Patent: August 12, 2025Assignee: Plasser & Theurer Export von Bahnbaumaschinen GesellschaftInventors: Herbert Woergoetter, Andreas Poeschl, Nikolaus Matzinger

Patent number: 12351218Abstract: 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.Type: GrantFiled: October 22, 2021Date of Patent: July 8, 2025Assignee: Amsted Rail Company, Inc.Inventors: Justin M.
