On the morning of April 2, XCMG 700-ton hydraulic excavator rolled off the production line successfully. Mr. Wang Min, Chairman of XCMG Group delivered a speech, in which he highly affirmed the achievements made by XCMG Excavator Machinery Business Division to strive for a world-class brand of the mining industry in China and pointed out XCMG always take the large set of mining machinery as a strategic industry and invested much capital in it. That’s why XCMG mining equipment has perfect cost-effective performance in the market.

During inspecting XCMG, China’s President Xi Jinping pointed out, “for key technologies and foundational information, asking others for help is like asking a tiger for its skin; therefore, we should have patience and tap our potentials to research and develop new technologies, which is called innovation-driven”.

Honored as “China’s Largest Excavator”, XCMG 700-ton hydraulic excavator is driven by two 1,700-horsepower motors, exceeding the power of two Type 99 Main Battle Tanks. Its weight is equivalent to that of 500 ordinary sedans, and overall length of 23.5 meters approximates to the body length of the largest creature on earth---adult blue whale. With the bucket width of 5 meters and bucket capacity of 34 cubic meters, the bucket can dig more than 50 tons of coal each time the leveraging maximum thrust pressure is 243 tons and stick digging force is 230 tons. The XCMG 700-ton hydraulic excavator can matches with XCMG 240-ton or 300-ton mining tipper. They are called “Mining Giants”, which can load and transport more than 30 thousand tons of coal in 8 hours. The highly-efficient operation is an undoubted major breakthrough in mining industry of China.

On top of that it is recognized as “the largest tonnage in China”, the 700-ton hydraulic excavator adopts many exclusive technologies including dual-power assembly coupling control system, high pressure system intelligent monitoring and fault self-diagnosis technology, modularization dual-power hydraulic driving system, and auto-oil supply self-adaptive chassis tension system with 52 independent patents. It has achieved breakthrough in centralized application of crucial technologies for the first time in the field of ultra-large type hydraulic excavator in China, marking that China has become the fourth country having R&D and manufacturing capacity for 700–ton and above hydraulic excavator in the wake of Germany, Japan and America.

In March 2018, XCMG hit an all-time high export of articulated dumper in China with 70 sets(including excavators, articulated dump trucks, loaders, etc.) to Central Asia and South Africa; Mining machinery of XCMG has successfully entered the high-end market which had been dominated by international giants of Europe, Japan, America, etc. Mining machinery of XCMG has gained favor from more and more clients, depending on prominent performance, reliable quality and service exceeding the expectations of clients; XCMG has become main supplier and significant participant for large-scale excavating machinery and mining machinery in the world, greatly promoting and leading the progress and development of large-scale open-pit mining machinery industry in China.
