Railroad well car

摘要

A railroad car for carrying containers has a car body mounted on trucks. The car body includes two side sills connected to two end frames. The side sills and end frames define an open well which is adapted for receiving a container. The floor of the well is defined by a container support frame assembly which is hung from the side sills by four hanger straps. The container support frame assembly includes two transverse support beams. The hanger straps are pivotally connected by transverse pins to the side sills and the transverse support beams such that the hanger straps are stressed primarily in tension only and they transfer tensile loads but not bending loads to the side sills.
