CNR advanced the development of new wagons through innovations and experiences. It leads the development of 70-ton and 80-ton wagons, which marked a new epoch in Chinese railway transportation for both speed and load. With the loading capacity increased 17-31% and speed up to 120 km/h, these wagons can form 5,000- to 20,000-ton heavy haul unit trains.
CNR manufactures a full line of freight wagons with axle load up to 40 tons, including covered wagons; open-top wagons for coal, ore, steel and timber; hopper wagons for grain, ore, fertilizer; flat wagons; double-deck container flat wagons; tank wagons for all types of liquid and chemicals; tipper wagons, as well as schnabel and depressed center wagons. Designed for economical loading and unloading, CNR’s innovative freight wagons offer operators and customers the advantages of great loading capacity and simple handling.
Key technologies include the components for: ZK6 bottom cross-braced bogie, E grade steel coupler and big capacity draft gear which have been proved to be the most advanced.
80-ton wagons have lightweight body made of aluminum or economic stainless steel and, therefore, increase the axle load go up to 25 tons.
State-of-the-art wagons not only replaced old ones but also put thousands of wagons successfully into world markets. The wagons we manufactured for Australia for transporting ores have an axle load of 40 tons, the highest in the world.
