Mine dump trucks are very large-scale engineering transport equipment. China has always depended on foreign imports. European, American and Japanese brands almost monopolized the domestic large-scale mining vehicle market. Faced with the continuous increase in domestic demand for mineral energy and deepening mining, large domestic engineering machinery companies such as Sanyi and Xugong are developing relevant mining dump trucks. The traditional Chinese CNR, which mainly produces rail vehicles, has taken the lead. A person from CNR told the editor that at present, the company has reached an intention of purchase with many domestic and foreign manufacturers, and soon the model will be put into large-scale production, and the series models of 220-360 tons will be developed and developed in succession to open up the field of mining machinery. .
CNR (601299) issued a report a few days ago that its first domestic 190-ton AC drive dump truck used in the research and development was offline, and its core AC drive technology had independent intellectual property rights. This also means that CNR has become the only host manufacturer in the world that has independent intellectual property rights for AC drive technology.
