This zinc mine needed a truck no one made, so they made their own (opens in new tab)

Zijin Mining couldn’t find an ultra-class electric haul truck that could get the job done at its Wulagen mine in Wuqia County, Xinjiang, so they designed their own: a 140-ton BEV haul truck with a huge, 770 kWh swappable battery pack. Then they built 290 of them. (!)
