CNR successfully developed the AC drive control system for the world's largest electric truck

Recently, the world's largest load-bearing 400-ton electric wheel dump truck AC drive control system project was successfully rolled out of Beijing Erqi Equipment Co., Ltd. (4.18, 0.07, 1.70%). The successful development of this technology broke through the monopoly of international giants such as Siemens and GE, and filled the gap in the core technology of the electric control system of electric wheels in China.

Electric wheel dump trucks are widely used in large-scale construction sites such as coal, iron, copper, gold and other open-pit mines, port terminals, water conservancy and hydropower construction sites, and transportation infrastructure construction. Transporting ore, raw materials or earthwork can increase mining productivity and reduce Transportation costs and broad market prospects, it is expected that in 3-5 years, China will add more than 10,000 electric dump trucks.

The 400-ton electric wheel car is currently the world's largest electric wheel car with the largest weight. The domestic heavy-duty electric wheel car electrical control system market has been monopolized by industry giants such as Siemens and GE. Relying on the mature AC drive control technology platform of diesel locomotives, Erqi Equipment Co., Ltd. is committed to the research and development of electric control systems for electric wheel vehicles. It has successfully provided a stable and reliable electric control system for domestic 190-ton electric wheel vehicles, and put them into operation. The electrical control system products cover dump trucks of various tonnages below 400 tons. Based on the innovative development idea of ​​“mastering high-end technology, technology leading development”, Erqi Equipment Co., Ltd. focused on technical advantages, integrated expert resources, and successfully solved the technical difficulties of the electric control system of heavy-duty electric wheel vehicles through multi-scheme demonstration and evaluation. Fully mastered the core technology of electric wheel vehicles, and truly made the core technology manufactured by Erqi Equipment Company become the wings that drive the electric wheel vehicle industry in China.
