FIELD: railway engineering.
SUBSTANCE: group of inventions relates to the field of railway transport, in particular to the frames of platform cars, as well as to flat cars with such a frame. The frame contains two end nodes and a longitudinal beam. Buffer beams with buffers are located at the end nodes. The longitudinal beam runs along the central axis and defines the bearing surface for the placement of containers and/or superstructures. The longitudinal beam contains integral upper and lower belts. The belts are located on top of each other. The belts are connected at the ends to each other and to the end nodes by means of integral longitudinal partitions.
EFFECT: increased strength of the frame.
