The first batch of 20 refrigerated semi-trailers delivered this time adopts Hongchang Tianma’s leading technology and advanced technology. Through program control, the foaming, insulation and pressing processes are automatically completed, thus ensuring that the compartment panels have good quality and insulation.

The Dongfeng Tianlong KX tractors matched with the refrigerated semi-trailers all use Dongfeng Cummins integrated power chain – Dongkang Z14 National VI engine + Yingdong AMT gearbox.

Among them, the Dongkang Z14 engine adopts an integrated and modular design, weighs less than 1,000kg, and is lighter than National V products. It has a power range of 480-600 horsepower, a maximum torque of 2750N·m, and a wide speed range of 900-1400 rpm. Low fuel consumption.

Yingdong AMT gearbox is an innovative product developed entirely based on automatic transmission applications. It adopts a reliable 12-speed dual countershaft design. It weighs only 298kg, 20% lighter than similar products, has a lubricating oil change capacity of 7.5L, and has an extra-long 60 The oil change interval is 10,000 kilometers, and the maintenance interval of the self-adjusting maintenance-free clutch is also 600,000 kilometers, which is 2-4 times that of the ordinary AMT clutch. More importantly, combined with intelligent control, the gear shifting is fast and logical, and the driving experience is smoother.

Guo Kai, Director of Zhongtong Cold Chain Operation Management Center

As an engine manufacturer, Dongfeng Cummins provides reliable power systems for our vehicles to ensure that the vehicles can operate stably under various conditions. The Dongfeng integrated power chain composed of the Dongfeng Cummins engine and the Eaton Cummins transmission installed in the first batch of delivered Dongfeng tractors (Dianlong KX) was also an important reason for our choice. We believe that the excellent performance and unique advantages of Dongfeng Cummins integrated power chain will help Zhongtong Cold Chain continue to reduce costs and increase efficiency.


Following the trend and taking advantage of the trend, with the rapid development of the refrigerated transportation industry, the competition for refrigerated transportation equipment is becoming increasingly fierce. More reliable, economical and efficient transportation equipment is undoubtedly what users want. Zhongtong and Cummins have a profound foundation for cooperation. There are more than 10,000 vehicles equipped with different models of Dongfeng Cummins power in the fleet, many of which have exceeded one million kilometers and are still in normal operation without major repairs.

Objectively speaking, my country’s cold chain transportation has developed rapidly in recent years and is huge in scale. Especially in the past five years, the compound growth rate has been as high as 17%. In 2022, the cold chain logistics market will reach 637.1 billion yuan.

Wang Zhixian, deputy general manager of Jiangsu Hongchang Tianma

The refrigerated truck is a product that we invested in related research and development 7 years ago. From the beginning, it has been in line with international advanced standards and kept pace with the world.

Wang Zhixian, deputy general manager of Jiangsu Hongchang Tianma, said that the advancement of refrigerated transportation equipment is inseparable from strong alliances. Cooperation with Dongfeng Commercial Vehicles, Cummins (China) and Carrier (China) will also promote the sustainable development of Hongchang Tianma.


In the face of the majestic blue ocean market, we must see that domestic cold chain transportation equipment still needs to be improved. Low-energy consumption, high-intelligence advanced equipment supported and empowered by Dongfeng Cummins’ integrated power chain is becoming an urgent need for users. This new vehicle delivery will not only help Zhongtong Cold Chain lead the way in fresh food, but also set a good example for the development of the industry. model.
