  • 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.
