Chinese enterprises have been lacking in the field of heavy construction machinery, so that foreign companies can rely on their own advanced technology level to "cut leeks", China not only needs to pay more expensive prices when purchasing machines, but also by the technology blockade of Western countries, but now this situation has been reversed by a company, XCMG Group in one fell swoop to create China's most cattle excavator, bucket capacity is huge, with strong work efficiency, can dig a mountain in half a day, itself weighs 700 tons, sales in overseas markets far more than the United States and Japan, XCMG is the most competitive and influential large-scale group enterprise in China's construction machinery industry, ranking 123rd in the list of the top 500 domestic manufacturing enterprises in 2019.

Excavator is a large multi-functional machinery, whether it is construction, transportation, water conservancy construction, or mining, or even military engineering construction can find its place of use, can be said to be one of the most important construction machinery, it is precisely because of its importance, from the 1970s onwards, Chinese enterprises began to develop and manufacture excavators, but at that time China's national strength was weak, the industrial system is not perfect, so in terms of production technology and talent reserves, compared with developed countries such as Britain and France, There is a big gap, so the quality of the products produced cannot reach the advanced level, so that China still has to purchase from foreign companies when it carries out infrastructure construction.
In order to solve this dilemma, by the 1980s, Chinese enterprises began to actively introduce advanced technology from foreign companies, the influx of advanced technology and the demand brought by domestic infrastructure construction promoted the rapid development of this industry, and XCMG also learned some advanced experience and technology from abroad, and applied it to the research and development process of domestic products, after continuous iteration and innovation, the final product was the XE7000 excavator weighing 700 tons.

This excavator can be said to be specially developed for mine excavation, a bucket can be dug up, more than 50 tons of ore, 50 times stronger than ordinary excavators, only need to carry out 6 excavation operations, can directly fill a mining truck with a load capacity of 300 tons, in order to provide enough power to the chassis and bucket, it is installed with two 1700 horsepower level giant motors, the total output power is even more than two main battle tanks combined.
A heavy machinery weighing 700 tons must be a complex system, so in order to monitor its own condition, it is also equipped with an intelligent control system, which can monitor the status of each important part, once an abnormality is found, it will automatically issue an alarm to remind the operator to pay attention to the maintenance, in addition, this system can also further assist the driver's operation, and even be able to automatically complete some relatively simple actions to reduce the driver's burden and improve the overall work efficiency, for any mine, Such excavators can greatly improve the overall operating efficiency, reduce costs and increase profits.

Of course, it is undeniable that even if the weight and excavation capacity of this machine are among the best in the world, it is still not the strongest excavator in the world, and the largest excavator in the world is the 1400-ton excavator built by Krupp, so XCMG will invest a lot of money in scientific research every year for the research and development of new excavators, and strive to completely defeat enterprises in other countries in the international market.
