Determination of common features and classification of fitting stops for flat cars

Abstract

Railways, being the basis of the country's transport system, provide timely and high-quality satisfaction of the needs of shippers and consignees in transportation. One of the most effective ways of cargo delivery is container transportation.For the transportation of containers, specialized rolling stock is used — platform cars equipped with special container attachment points — fitting stops. The design of stops for container fittings limits the spontaneous displacement of containers, prevents them from tipping over. Various designs of fitting stops are used in practice and exist only in the information representation in the form of patents and technical documentation. As a result of the comparative and statistical analysis, similarities and differences in the design were established, and common features were determined. The designs of stops and devices for fixing containers on platforms used in Kazakhstan and the United States are considered. The presented classification of fitting stops is based on the results of the analysis of the structures of fitting stops installed on specialized platform cars operated in the Russian Federation. Fitting stops of specialized platform cars for container transportation are classified in three directions.The classification obtained as a result of the study allows us to establish the uniformity of the structures used for fitting stops of platform cars for the transport of containers and opens up the possibility of finding a way to improve certain structures united by common features.
