Abstract:
La presente invención corresponde a una traviesa de vehículos ferroviarios mediante la cual se conecta el chasis y el bogie. La traviesa comprende un perfil central y dos perfiles laterales dispuestos una a cada lado del perfil central. El perfil central tiene una 5 sección transversal rectangular. La sección transversal rectangular se extiende a lo largo de un eje longitudinal. Al interior de la sección transversal rectangular se disponen dos nervaduras. Cada perfil lateral tiene una sección transversal hexagonal. Al interior del perfil hexagonal se dispone una primera nervadura horizontal, una nervadura vertical, una segunda nervadura horizontal, una primera nervadura oblicua, una segunda nervadura oblicua y una tercera nervadura oblicua. Los perfiles laterales son simétricos axialmente con respecto a un eje vertical, el eje vertical es perpendicular al eje longitudinal. La invención también comprende el procedimiento de ensamble de los perfiles de la traviesa y el proceso para disponer la traviesa en el chasis de un vehículo ferroviario.
Abstract:
A rail car underframe comprising:a longitudinally extending sill, the sill comprising an elongate structural member defined by at least one sill wall; a plurality of underframe side members extending outwardly from the sill, each side member comprising a structural member defined by at least one side member wall; a wall member forming at least a portion of the sill wall and at least a portion of at least one side member wall.
Abstract:
Embodiments of the present disclosure include a rail car for supporting and transporting one or more containers storing proppant therein. A spine member extends from a first end to a second end of the rail car, and having a variable height that is greater at a midpoint than at the ends. A bolster is arranged on a top surface of the spine member, extends laterally in two directions, and has a greater width proximate the spine member than at a distal end. A mounting platform is positioned on the distal end of the bolster, has a container surface that receives the one or more containers, and extends vertically from the bolster to position the container above a top surface of the bolster. A locking assembly is positioned on the mounting platform and secures the one or more containers to the rail car when moved to a locked position.
Abstract:
The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes improvements in functionality, manufacturability and/or modularity and, therefore, can result in a reduction in system component costs, manpower and/or implementation. The rail transport system includes a dump loop and components thereof for enabling unloading of the rail cars in a predetermined location. The components thereof may be designed to be modular to allow for ease of manufacture and installation of the dump loop. The components may be prefabricated for later use on site.
