  Recently, Changzheng Heavy Industry's invention patent application for railway freight car bodies suitable for small gauge limits was successfully authorized. To date, the company has accumulated 8 invention patents.
 
  This invention effectively solves the problem that the traditional structure has a poor strain effect on vehicle limits, especially the width of the connection between the lower part of the side wall and the floor cannot meet the requirements of mechanized unloading of bulk cargo, the adaptability of the smaller gauge width in this area is poor, and it affects the safe operation of the vehicle. At the same time, it also saves manufacturing costs to a certain extent, further enhancing the company's overall competitiveness in the industry. (He Zhenliang)
