If you were given a set of figures: 549 tonnes (about the weight of three blue whales) and 18.3m (the height of a six-storey building), what would you expect? Is it a monster? It's quite spectacular, because it's one of the largest opencast mining facilities in the world right now. & ndash; Weight and height of Hitachi ex 5600-7 super large mining excavator (when the mechanical arm reaches the highest working height).

▲ Hitachi construction machine ex5600-7 super large mining excavator

Mining equipment is about reliability and durability, day in and day out, how strong a heart does it have? For the machine & other; Big guy & throughout; Powered by two cummins 1,500hp (1,119kw) QSK50 engines, they not only meet the latest EPA Tier 4 emissions standards, but also ensure the efficiency of the equipment in harsh mine conditions.

▲ cummins QSK50 high-horsepower engine

Cummins QSK50 Tier 4 engines reduce emissions of diesel particulate matter (PM) and nitrogen oxide (NOx) by 80% and 55%, respectively. In order to adapt to the high load, long time mining operation, QSK50 has a strong power output, even in high altitude harsh conditions, can almost meet 7 days /24 hours of high intensity work. Combined with cummins advanced in-cylinder combustion technology, QSK50 not only has strong power but also a long overhaul period, providing a strong guarantee for efficient attendance of mining equipment.

QSK50 is widely used in large harvester, excavator, loader, bulldozer, grader and other equipment. It provides power support for the mining equipment of komatsu, Hitachi construction machinery, liebherr, XCMG group, northern stock and other well-known enterprises at home and abroad, and helps them. Big guys; Active in the world's major mines. Mines are particularly popular in Australia.

Popular science: known as “ A country on the back of a sheep. Australia said not only mutton, wool, cashmere, lanolin oh, there are also quite rich mineral resources, coal, iron, bauxite resources are particularly prominent, so, also known as Australia “ Countries on harvesters .

In the field of mining equipment application in China, XCMG XE3000 excavator equipped with a single QSK50 has been in service for up to 5 years, and is currently used in wuhai coal mine and alashanzhula gold mine in Inner Mongolia.

Equipped with two QSK50 XE7000, is currently the largest excavator in China, there are “ The first diggings in China ” Meiyu has been put into operation in Inner Mongolia since November this year.

Another successful application of QSK50 is the NTE200 rigid dumper, a vehicle owned by northern shares, which is also widely used in coal mines around the himin river and heping shuo.

As a performance juggler, this big guy has far more power than that. Let's return to the story of QSK50 in other fields, remember to come back oh
