The invention belongs to the field of container flat cars, specifically relates to a low-center-of-gravity container flat car and aims at solving the problems of relatively high center, poor running stability and high car deadweight of the existing container flat cars. The Low-center-of-gravity container flat car comprises a car body. The car body is of a plate welded structure and comprises a towing beam, a middle beam, an end beam, a sleeper beam, a large cross beam and a small cross beam; the middle beam is of a dual-web welded box-type structure, and also of a fish belly-shaped structure high in middle and low in both ends; the towing beam, the end beam, the sleeper beam, the large cross beam and the small cross beam all are of the dual-web welded box-type structures; the webs of the middle beams have the upward deflection of 25mm; impact baffle plates are arranged at the two end portions of the car body; the webs of the towing beams are bent outwards at the end beam. The height of the container bearing surface of the container flat car away from a track surface is reduced, the center of gravity of the vehicle is reduced, and the running stability and the running quality of the vehicle are improved; the car body is welded only by use of plates, so that the manufacturing cost can be reduced, the deadweight of the car can be reduced and the carrying capacity of the car can be improved; in short, remarkable economic benefit and social benefit can be produced.
