Company Profile

The predecessor of Lengzhi equipment branch of CRRC Changjiang Vehicle Co., Ltd. is the business unit of cryogenic and general cooling products of CRRC Changjiang Vehicle Co., Ltd. Changjiang Company is a first-class subsidiary of CRRC. Its headquarters are located in the thoroughfare of nine provinces, where resources are gathered and Wuhan City, Hubei Province, is under construction.

As a backbone enterprise of CRRC, Changjiang Company has built a first-class research and development base for railway freight cars, a first-class manufacturing base for railway freight cars and a first-class export base for railway freight cars. It has strong technical force and advanced research and development means. The range of railway freight cars researched and developed includes 12 product series, which is the only research and development base for railway refrigerated vehicles in China, which provides a large scale for the country The amount of railway transportation equipment, the export of railway freight products throughout the world. At the beginning of the 20th century, the liquid hydrogen tank car was developed by the Yangtze River Railway Company in the early 1990s, and has been used in China's railway transportation industry. In recent years, to meet the needs of the national economy for clean energy transportation, the Yangtze River company has concentrated its advantageous resources and successfully developed liquefied natural gas (LNG) transportation and storage equipment, including various types of LNG storage tanks, LNG railway tank cars, rail public water combined LNG tank containers, etc. the developed liquefied natural gas railway tank cars have filled in the domestic blank. LNG railway tank cars and tank containers will become a new generation of reliable long-distance, large transport capacity, low-cost LNG transportation equipment.

Changjiang Company has built a national enterprise technology center, and has obtained C1 (railway tank car) / C3 (tank container) / A2 fixed pressure vessel design license, C1 [railway tank car (including low temperature insulation tank body)], C3 [tank container (including low temperature insulation tank body)] issued by general Administration of quality supervision, inspection and Quarantine of the people's Republic of China, and quality and technical supervision of Hubei Province The D1 / D2 pressure vessel manufacturing license issued by the Supervision Bureau has the ASME u-grade steel seal of American Society of mechanical engineers, the movable tank tank certificate of China Classification Society and relevant factory approval, and the test and research center of the company has CNAs approval, which is the Engineering Laboratory of Hubei Province.

The company has built an industry-leading cryogenic insulation pressure vessel manufacturing base, a large workshop with controllable temperature and clean, equipped with P + T plasma welding machine, Italian imported Davi plate bending machine, CNC profile bending machine, 25m large-scale radiographic inspection room, intelligent suit and winding equipment, cleaning winding room, imported Agilent and Laibao vacuum pumping units, Italy imported KANGLONG foaming equipment And other advanced technological equipment.

In order to further promote the development of railway refrigerated storage and transportation equipment, energy and chemical storage and transportation equipment, in August 2016, Changjiang Company concentrated all the research and development and manufacturing of cryogenic and general cooling products and relevant resources, and registered and established a cold intelligence equipment branch company in Wuhan. Lengzhi equipment branch is committed to the R & D and manufacturing of cryogenic and general cold storage and transportation equipment, is committed to providing customers with cold chain logistics system solutions, and is committed to providing intelligent products and intelligent services to the society.
