On September 27, the ZTE520, claimed as the “world’s largest” hybrid mining truck, rolled off the Zoomlion assembly line in Changsha, Hunan. The Chinese OEM described it as “another historic breakthrough in domestic mining equipment, marking the further advance of China’s mining equipment into the high-end field of the global industry.” The other contender to this largest hybrid mining truck title is SANY’s SET320S, also with a 300 t payload, unveiled in July 2024.
Huang Qun, Vice President of Zoomlion, Yuan Ye, Assistant President of Zoomlion, Wang Peng, Director and Deputy Secretary of CRRC Zhuzhou Electric Locomotive Research Institute Co Ltd, Zhuang Jun, Deputy General Manager of CRRC Qishuyan Research Institute Co Ltd, and Tan Guirong, Senior Vice President of Guangxi Yuchai Machinery Co Ltd were all in attendance at the ceremony.
Zoomlion says it has “fully responded to the call of national green mine construction and equipment technology localisation” with the ZTE520 with the truck integrating key domestically produced components for the entire machine.
The ZTE520 has a total weight of 520 t and rated load of 300 t. Zoomlion says it features a new generation super hybrid drive system and high torque electric wheel drive system, both developed together with CRRC, along with efficient liquid cooling heat dissipation technology, and is equipped with a large domestic hybrid diesel engine (16-cylinder, 52-litre diesel engine with 2,100 hp) from Guangxi Yuchai, along with it says the industry’s largest ternary lithium power battery. The truck is over 9 m in width and 7 m in height.
It has a total power of 3,200 hp, to achieve greater power performance, energy management and economic performance. Compared with the traditional diesel engine only mining truck of the same class the product’s overall performance it says increased by 16%, with transportation efficiency increased by 10%, together with a comprehensive energy saving of 15%. Its rated lifespan is 60,000 hours.
Localising all the key core components in the research and development process Zoomlion says has ensured the safety and stability of the supply chain, but also greatly reduced the costs for users.
Zoomlion “will continue to innovate, provide customers with more high-end mining equipment, and contribute more powerful Zoomlion force to the high-quality and sustainable development of China’s advanced equipment manufacturing industry,” Yuan Ye said. The truck was unveiled at the same time as a new large Zoomlion hydraulic excavator, the ZE4000G, which is 8.1 m tall and weighs more than 400 t, intended as a good match for the new ZTE520 truck.
