The then large JIEFANG CA-390 was powered with a Chinese Chingfa C2956 V12 720 horsepower diesel engine that produced enough power to match several other similar dumptrucks at that time and its production was targeted as a quarry and mine vehicle, these are designed to carry 105 Tonnes of material when fully loaded so it became quite popular as the largest mining dumptruck available in China during the 1970s and 1980s.
