On the morning of September 27, with a loud whistle, the world's largest hybrid mining truck ZTE520 independently developed by Zoomlion rolled off the production line in Changsha, Hunan. This is another historic breakthrough in domestic mining equipment, marking that my country's mining equipment has further advanced into the high-end field of the global industry.

Huang Qun, Vice President of Zoomlion Heavy Industry Science & Technology Co., Ltd., Yuan Ye, Assistant President of Zoomlion Heavy Industry Science & Technology Co., Ltd., Wang Peng, Director and Deputy Secretary of the Party Committee of CRRC Zhuzhou Electric Locomotive Research Institute Co., Ltd., Zhuang Jun, Deputy General Manager of CRRC Qishuyan Research Institute Co., Ltd., Tan Guirong, Senior Vice President of Guangxi Yuchai Machinery Co., Ltd. and other leaders and guests attended the off-line ceremony.

Mining trucks are the absolute main equipment for open-pit mining. Among them, large-tonnage electric-driven mining trucks have become recognized as high-end equipment in the industry due to their complex technology and great manufacturing difficulty. Zoomlion fully responded to the national call for green mine construction and localization of equipment technology, and launched the world's largest hybrid mining truck ZTE520. Its key components are fully integrated and domestically produced, breaking the foreign technology monopoly. The hybrid technology has reached the international leading level, leading the development direction of localized large-tonnage hybrid mining trucks and becoming a new benchmark for the smart and green mining machinery industry.

According to reports, the ZTE520 mining truck has a total weight of 520 tons and a rated load of 300 tons. It has a large carrying capacity and high operating efficiency. It is a "powerful athlete" for open-pit mining and large-scale earthwork transportation and construction. It innovatively applies a new generation of super-hybrid electric drive system, high-torque wheel hub drive system and high-efficiency liquid cooling technology. It is also equipped with the largest domestic hybrid diesel engine for vehicles and the largest ternary lithium power battery in the industry. The total power reaches 3,200 horsepower, achieving the optimal matching and extreme optimization of power performance, energy management, and economic performance. Compared with traditional products, the overall performance is improved by 16%, the transportation efficiency is improved by 10%, and the comprehensive energy saving is 15%. All indicators are firmly in the forefront of the industry.

It is worth mentioning that the ZTE520 mining truck has achieved the localization of all key core components during the research and development process, breaking through relevant technical barriers, which not only ensures the safety and stability of the supply chain, but also greatly reduces the user's use cost. It can be widely used in various large open-pit mines with an annual output of more than 30 million tons, providing strong support for the efficient mining and green mining construction of mines.

Adhering to the concept of "technology is the root, products are the foundation", Zoomlion is continuously leading the industry's intelligent, digital and green transformation and upgrading, and has created a series of "world's best" and "industry first" benchmark products. "The launch of ZTE520 marks that Zoomlion's mining machinery sector has fully entered the high-end mining equipment market and is constantly accelerating in the new journey of high-quality development. Zoomlion will continue to innovate, provide customers with more high-end mining equipment, and contribute stronger Zoomlion power to the high-quality and sustainable development of China's advanced equipment manufacturing industry!" Yuan Ye said.
