Do you know the history of "Jelly Vehicle"?

Visible "old objects"

Invisible story behind

Paying the footsteps of development

Listen to the voice of "old objects"

Inherit the spirit of endless struggle

The original technical drawings of the B22 mechanical refrigerated vehicle (referred to as "machine cold vehicle") are from vehicle manufacturers and former democratic Germany "Dehao Vehicle Factory". The thick yellowing drawings used to be the main standard for maintenance and use of special cargo transportation equipment imported.

Earlier railway people seemed to study, absorbing and transforming with passion and research, and continuously learned practice, absorbing and transforming, and gradually developed their own technical standards, extending a variety of special goods flow equipment maintenance systems.

Time, the drawings of that year have already completed its historical mission, and became "old objects", witnessing the development and progress of technology, and telling the story of the Chinese railway cold chain logistics business from learning to self -reliance to surpassing.

In the 1990s, the B22 -type machine cold vehicle was imported to our country, consisting of a mechanical vehicle and a four -section cargo vehicle, which mainly undertakes the task of fresh cold and easy -to -rot cargo transportation.

With the improvement of my country's scientific and technological level and the enhancement of independent research and development capabilities, the B23 domestic aircraft cold vehicles, B10 single -section machine cold vehicles, and BX1K refrigerated container transportation vehicles have come out one after another. Railway cold chain transportation equipment has continued to grow.

The original supporting drawings of the vehicle mainly include the introduction of the car body component and the technical requirements of diesel, electrical appliances, and refrigeration, which provides technical support for early vehicle use and maintenance. Time has changed, and these drawings have also become "old objects", quietly displayed in the showcase, becoming a development mark of the era.

In the early days of reform and opening up, my country's cold chain logistics transportation capacity was lacking. As the main carrier -carried equipment, the engine cold vehicles from Lin Haixue to tropical islands, from Gobi, desert to the east China Sea, across the fields of the field, and reached all directions. Delicious dishes such as seafood are delivered to tens of thousands of households.

Nowadays, the mobile cold storage transformed from the cold vehicle stands in the field. Fresh fruits such as dried apricots and sea buckthorn fruits picked by farmers can directly enter the warehouse to refrigerate. To the city's sales, it greatly reduced the cost of transportation, opened up the "last mile" of the cold chain logistics, and made new contributions to the prosperity of the "agriculture and rural" industry.
