"Beijing made" 240 tons of electric drive dump truck off the assembly line

It is understood that this yellow-colored "giant" with a height of more than 7 meters and a carrying capacity of 240 tons has set a new record in the domestic mining car manufacturing industry in many technologies. Deng Li, an engineer involved in the development of the vehicle, introduced that the CR240E has changed the status quo in which traditional mining vehicles can only use diesel fuel, and has taken the lead in realizing dual-use of diesel and natural gas, thereby reducing air pollution. According to calculations, after using the dual-fuel technology, each vehicle can save more than 1.5 million yuan in fuel cost per year for users and reduce carbon dioxide emissions by 60 tons. In addition, for the first time, the vehicle uses the energy recovery system independently researched and developed by CRRC to further reduce the fuel consumption. The “cross-traffic” transmission system used by vehicles also breaks the monopoly of foreign technology.

It is understood that with the rapid development of related industries and the upgrading of large-scale mine equipment, the demand for heavy mining electric wheels will increase. The demand for this vehicle in the South American market is relatively strong. Only the BHP Chile branch needed to purchase 90 240-ton or more mine cars from 2019 to 2025. The Beijing Erqi Locomotive Company is expected to enter the global market through cooperation with the Chilean BHP project. As the core components of the vehicle are the CRRC Group's own products, it has a greater cost advantage in the international market.

Ma Jianxun, chairman of Beijing Erqi Motorcycle Co., Ltd., said that the off-line marking of the CR240E mine car marks that Beijing Erqi Motorcycle Co., Ltd. has taken a solid step forward in the process of perfecting the serialization of mine car products. Since then, the mine car product family has added important One member. Beijing Erqi Motorcycle Co., Ltd. has successively developed the first set of DC electric drive control system for mine cars and the first set of AC drive system for mine cars in China, achieving a major breakthrough in the core technology of the car, and taking the forefront of domestic technology in this field. Relying on the technical capabilities possessed by the mine car industry and the strength of rail transportation equipment manufacturing, Beijing Erqi Locomotive will make the mining industry a major strategic direction for the company's future transformation and development, and is committed to building an internationally renowned brand of China Railway Mining Equipment.
