On November 23, Liancheng Group's first 330T mine card brake resistor went offline, marking that Liancheng Group broke the foreign technological monopoly on large-tonnage brake resistors and took the lead in completing the localization of large-tonnage brake resistors and supplying them in batches.

Mineral resources are an important material basis for economic and social development. The world's existing 2/3 mineral raw materials are open-pit mining, and large open-pit mining machinery is a manufacturing highland. 330T mining truck is an important model of Zhuneng Group responsible for open-pit coal mine transportation operations, but also the domestic large-tonnage mine card electric drive system depth localization project, has a very important strategic significance. As the core component of the mine card electric drive system, the 330T mine card brake resistor independently developed and produced by Liancheng Group not only breaks through the technical bottleneck and breaks the foreign monopoly, but also means that Chinese mine card enterprises are no longer restricted by the exclusive supply of large-tonnage mine card electric drive system by foreign enterprises.

The 330T mine card braking resistor adopts an original circular structure, which is another major breakthrough of Liancheng Group after successfully developing and producing 110T, 150T, 170T, 220T, 240T, 260T and other specifications of braking resistor. Compared with similar products, it is smaller in size, lighter in weight and more cost-effective.


In recent years, Liancheng Group has driven the upgrading of the rail transit industry with innovative development, and has focused on promoting the application of large-tonnage circular braking resistor technology in the field of mining machinery. The offline of 330T mine card brake resistor is also another major milestone for Liancheng Group's rail transit technology to extend forward and backward!
