QSK50 is widely used in large mining trucks, excavators, loaders, bulldozers, graders and other equipment. It provides power support for the mining equipment of well-known enterprises at home and abroad such as Komatsu, Hitachi Construction Machinery, Liebherr, Xugong Group, and Beifang Co., Ltd., helping these "big guys" to be active in major mines around the world. It is especially widely used in Australian mines.

Mining equipment pays attention to reliability and durability. What a strong heart does it have to run day after day? Powering this "big guy" are two Cummins 1,500-horsepower (1,119-kilowatt) QSK50 engines that not only meet the latest EPA Tier 4 emissions standards, but also ensure equipment efficiency in harsh mining conditions.

In order to adapt to high-load and long-term mining operations, the QSK50 has a strong power output, which can almost meet 7 days/24 hours of high-intensity work even under severe conditions at high altitudes. Combined with Cummins' advanced in-cylinder combustion technology, QSK50 not only has strong power but also has a long overhaul period, providing a strong guarantee for the efficient attendance of mining equipment.

As a high-horsepower engine with high performance and numerous praises, the energy of this big guy is far more than that. Let's go back and talk about the story of QSK50's great performance in other fields, remember to come back

Popular science: Australia, known as the "country riding on the back of sheep", not only has mutton, wool, cashmere, and lanolin, but also has abundant mineral resources, especially coal, iron, and bauxite resources.
