  • Patent number: 11976424
    Abstract: Systems and methods for using a mobile crane assembly are provided. The mobile crane assembly includes a mobile crane having a first truss assembly and a second truss assembly spaced apart and movable relative to one another. The first truss assembly and the second truss assembly are each coupled to a rail car end assembly. The mobile crane further comprises an upper gantry assembly movable along the first truss assembly and the second truss assembly. A flat cart is coupled to the rail car end assembly, and a material handling cart is received upon the flat cart and is configured to move between the flat cart and the rail car end assembly based upon input from a controller in electrical communication with the upper gantry assembly.

  • Publication number: 20050231387
    Abstract: A method and apparatus for monitoring vehicle violations at a railroad crossing, the method comprising the steps of providing a video camera at the crossing, using a processor to monitor information from the railroad crossing to determine when a traffic violation has likely occurred and when a violation has likely occurred, presenting video of the violation occurring to a system operator via a display screen, providing an input interface for the operator to confirm that a violation has occurred and when the operator confirms that a violation has occurred via the interface, at least one of generating a citation and storing a video clip of the violation for subsequent use.
