Chinese environmental technology firm Zijin Longking has unveiled its latest battery electric mining truck, a 350-tonne behemoth that the company proudly boasts is the largest-tonnage battery electric mining truck in China – and so likely the world.
Zijin Longking, a subsidiary of Chinese mining giant Zijin Mining Group, unveiled the ZL230E last week after it rolled off the production line at the Longking Smart Environmental Protection Industrial Park.
The ZL230E features a gross vehicle weight of 350 tonnes, empty weight of 120 tonnes, and a maximum payload of 230 tonnes, with a heaped body capacity of 125m³.
“It boasts comprehensive advantages such as low energy consumption, high reliability, easy maintenance, and large transport capacity, fully meeting the needs of long-distance transportation, heavy-load climbing, and continuous operation under complex conditions in large mines,” said Huang Wei, president of Zijin Longking.
“This effectively improves mine transportation efficiency, reduces operating costs, and provides strong equipment support for the construction of green mines.”
A pair of 800 kilowatt (kW) motors power the truck, backed by what Zijin Longking describes in their press release as “a large-capacity, long-life superchargeable battery system” that is capable of rapid charging to 90 per cent in only 25 minutes.
A recent investor report from Zijin Longking adds a little more information regarding the ZL230E. Referring to the LK350E, the truck’s previous model number, the company states that the truck’s battery capacity is 1,400 kilowatt-hours (kWh).
It is expected that the ZL230E will soon be placed into operation with parent company Zijin Mining, helping to further boost the miner’s fleet of battery electric mining trucks even further – which already sits at 1,719 units in 2025.
The ZL230E’s debut comes less than two months after the company also debuted the LK220E battery electric dump truck, which rolled off the production line in December 2025. Zijin Mining is already operating 300 of these trucks, some weighing up to 140 tonnes and featuring swappable 776 kWh batteries.
