en.Wedoany.com Reported - Recently, the first mass-produced Zijing Longking LK220E electric mining trucks rolled out of the company's factory in Longyan City, Fujian Province, China. On the same day, a signing ceremony for a new contract for the larger-tonnage LK350E electric mining truck was also held at the factory. Zijing Longking stated that its pure electric mining trucks have now achieved the leap from prototype vehicles to batch delivery.
The Zijing Longking factory is located in the Longking Smart Environmental Protection Industrial Park. The company stated that since Zijin Mining became its controlling shareholder in 2022, it has established a dual-drive strategic transformation of "Environmental Protection + New Energy." In April 2026, the company announced: "Due to the advancement of strategic transformation and business structure optimization, and to align the company name with its actual operations and development strategy," it decided to change its name to "Zijing Longking Environmental Protection and New Energy Co., Ltd.," abbreviated as "Zijing Longking." The company added that this name change highlights the core position of its new energy business and its synergistic advantages with Zijin Mining.
The LK220E electric mining trucks delivered this time have a payload capacity of 140 tons and will be sent to Zijin Mining's Julong Copper Mine in Tibet, China, covering a transportation distance of over 5,000 kilometers. The average altitude of the mining area is 5,300 meters. Since February this year, this model has been put into trial operation at the Zijinshan Gold and Copper Mine in Shanghang County, Longyan City, Fujian Province, and the Julong Copper Mine. Zijing Longking stated that on-site operational data shows the LK220E achieves a stable average daily transport volume of over 2,000 tons, with an availability rate exceeding 90%. Compared to electric mining trucks of the same class, its transport energy consumption is reduced by more than 17%. The company pointed out: "In response to the extremely complex working conditions at the Julong Copper Mine in Tibet, Zijing Longking, through precise design, successfully overcame the challenges of heavy-load continuous operation in complex environments such as high altitude, extreme cold, and steep slopes, filling a gap in high-altitude, large-tonnage pure electric mining dump truck products, delivering significant environmental and economic benefits."
Based on the stable operation of the LK220E, Julong Copper Industry signed a procurement contract with Zijing Longking for the 230-ton class LK350E electric mining truck. At the signing ceremony, Huang Wei, President of Zijing Longking, stated: "The stable and efficient operation of the LK220E at the Zijinshan Gold and Copper Mine and the Julong Copper Mine has fully verified the product's technological advancement, environmental adaptability, and sound economic viability." He revealed that an autonomous driving LK110EI intelligent mining truck will also roll off the production line within the year. Che Xian, General Manager of the Julong Copper Mine, stated that as China's largest copper mining enterprise, Julong Copper Industry has always shouldered the mission of setting a benchmark for high-altitude mines nationwide. He pointed out that Zijing Longking's first LK220E electric mining truck has withstood the tests of complex working conditions such as high-altitude conditions and frigid climates, with its energy costs reduced by nearly 80% compared to traditional diesel mining trucks.
