ABSTRACT:
A railroad freight car includes a loading platform and two wheelsets, two double-axle running gears or two bogies, and cushioning is effected by leaf suspension springs suspended by links from spring brackets. The object of the invention is to provide a railroad freight car by using simple, economic devices, in which a facility is provided for driving the railroad freight car beneath cargoes, especially swap bodies or interchangeable containers, for raising the loading platform and, following the reception of the cargo, for lowering the loading platform back into a travel position so as to enable the railroad freight car to be loaded and unloaded independently from loading appliances extraneous to the car. This object is achieved by providing a lifting element interposed between each suspension ring and an associated spring bracket of the loading platform or of the bogie frame. The lifting element can raise the loading platform relative to the wheelsets or to the double-axle running gear or with the bogie frame, relative to its wheelsets.
