By contrast, Chinese open-pit mines predominantly use electric shovels with a bucket capacity of 4–10 m 3 and trucks with load capacities of 25–75 t. The typical truck loads weigh approximately 120 to 170 t. China's largest open-pit mine (a single quarry) has an annual output of only 8–12 million t of iron ore.
