If the development of China's machinery heavy industry is written into a book, it is definitely a legend.
Excavators are the highest unit price products in construction machinery, and excavators are indispensable as the highlight of engineering infrastructure.
In recent years, China, Japan and the United States have formed a situation of three countries in excavator enterprises.
The United States has always occupied the first place in the world, and in recent years, Japan has also been pursuing head-on, and China's development cannot be underestimated.
In the "2020 Global Excavator Manufacturers", in the top 20, Japan accounts for 7, China accounts for 5, although the United States only has two, but the United States Caterpillar is an absolute industry giant.
Caterpillar, founded in 1925, is the world's largest manufacturer of construction machinery and mining equipment, one of the world's largest manufacturers of gas engines and industrial combustion turbines, and the world's largest manufacturer of diesel engines.
The first is Japan's representative company, Komatsu Manufacturing, which was founded in 1921, earlier than Caterpillar in the United States, and is an absolute giant of Japanese construction machinery and mining machinery manufacturing companies.
Komatsu not only has a good business ability but also a particularly vicious eye, as early as 1956, he entered the Chinese market.
Because China's manufacturing capacity at that time was very poor, unable to produce heavyweight excavators, Komatsu Group saw the timing and tried its best to see the timing to enter the Chinese market.
Of course, this is also due to Japan's unique geographical location, and the excavators made by Komatsu are also quite excellent in terms of service and performance, so Komatsu has gained a firm foothold in China, and this station is 64 years.
When New China was first founded, it could not even make a tractor, and later, China's heavy industry rose, and the rapid development rate stunned the developed countries, which also made many developing countries envious, and also ended the situation of being subject to people for many years.
At present, many large machinery in China, we have independently mastered the main core technology.
In the field of heavy machinery, China no longer has to be subject to any country. Not only that, but it can be exported on many machinery, especially excavators produced in China.
In the past 64 years, the rapid development of China's heavy industry has continuously impacted these foreign brands, and with the advent of a batch of domestic machines, the performance of domestic excavators is gradually improving, and even surpassing these foreign brands.
In China, there is a popular advertising slogan, "mining technology to see Lanxiang, excavation and manufacturing to see XCMG".
As early as 2013, China spent up to 1 billion yuan on the need to develop Neng Mongolia and purchased a Komatsu ex 8000-6. This Hitachi EX8000-6 excavator was the largest hydraulic excavator in the whole of Japan at that time, and now this excavator has been working for more than 7 years. Even now, the Hitachi EX8000-6 is still the number one in the excavator.
In 2018, XCMG Group's self-developed XE7000 came out, officially launched a challenge to Komatsu, whether it is the performance of mining, engine, and after-sales, XCMG Group is already the only one in China.
With the official advent of China's XE7000, more and more people have begun to compare Hitachi EX8000-6 with XCMG's XE7000, is Hitachi EX8000-6 better or XCMG XE7000 more advanced?
XE7000 VS EX8000-6
We all know that it is important to know a person at first glance, and the first glance is the appearance, and the appearance of the excavator is the size of the excavator.
Even now, the EX8000-6 is hard to find a machine larger than its type, which is 10.5 meters long, 8.7 meters wide, and nearly 10 meters high, equivalent to the height of a four-story building. The weight is as high as more than 800 tons.
The most important tool of the excavator is the shovel, such a large excavator shovel must not be small, ex8000-6 shovel has two, one is a loading shovel with a capacity of 40 cubic meters, and the other is a backhoe with a capacity of 43 cubic meters.
Put it this way, a shovel will take six 11-ton trucks to pull it up, and someone in Japan once made a comparison, using the Hitachi EX8000-6 to bulldoze Mt. Fuji in just one month.
The problem that many people wonder is that japan's narrow land area, this kind of excavator can not be built more than a few times.
In Japan, where minerals were originally scarce, the biggest purpose of manufacturing such a machine was to sell it for money, but China spent a lot of money to buy it.
With the development of the times and the progress of science and technology, China's industrial manufacturing industry has also come to the fore.
In the case of China's XCMG, the XE7000 excavator is manufactured to benchmark the Hitachi EX8000-6, which was named china's most famous when it was not yet available, and sat on the name of China's largest hydraulic excavator when it came out.
XCMG XE7000 is 24 meters long, more than 9 meters wide, and about 9 meters 5 high, and its backhoe can accommodate 34 cubic meters of ore. With the same work requirements to start the XE7000, it only takes a week to hollow out the 200,000-ton mine.
Of course, the bucket capacity of the excavator is only one aspect.
It is the engine that can start the excavator, so it is understandable that the engine is the heart of the excavator.
We know that the best engine for Japanese cars is the engine, but the XCMG xe7000 engine is better than the Hitachi EX8000-6.
First of all, the engine of the Hitachi EX8000-6 uses a single motor, and the overall output power is 1200kw, while the XCMG XE7000 uses a high-efficiency motor, and the overall output power is as high as 1250kw.
Many people do not understand what the lack of this 50kw means?
To put it simply, XCMG's excavation speed will be faster, and it takes 15 minutes to dig a soil Hitachi EX8000-6, but XCMG's XE7000 only takes 10 minutes. Therefore, XCMG's xe7000 is even better.
The business card of Chinese machinery
So which one will Chinese projects favor in choosing large excavators after that?
First of all, Xu works as a local brand in China, has inherent advantages, leaving aside the domestic brand, but buying a Hitachi EX8000-6 from Japan requires a lot of money and time, buying a Hitachi EX8000-6 from Japan, and it takes time to actually ship it.
Then you have to buy it back and put it on yourself, and you need to spend another time and money. And the biggest flaw in imported things is that once it fails, a small screw must be returned to the original factory to buy, so that it seems time-consuming and troublesome.
Xu work is a domestic brand, maintenance and after-sales are more convenient, and XCMG XE7000 is only recently introduced, therefore, the scientific and technological content is definitely better.
For example, XCMG XE7000 excavator above the fault self-test system, which is connected with XCMG's own system, which has a problem with the machine, will be fed back to the platform by the machine, the platform will immediately eliminate the fault maintenance after receiving the information, so in comparison, XCMG's after-sales is better.
Hitachi EX8000-6, as a veteran of the engineering world, may be more convincing from seniority, but the recent online vocabulary is called "feelings." ”
No one will pay for the feelings, on the construction site, relying on strength, who can solve the problem better and faster, who has more right to speak.
There has been such a statistic, XCMG Machinery's export rate has created the highest in China, has been the first in the industry for thirty years, and the scope of sales directly covers 183 countries and regions around the world, becoming the business card of Chinese machinery.
The arduous journey of Chinese excavators
The road ahead is long, and it is far from being repaired.
Although China's excavator technology started late and the steps are low, the development of China's machinery industry has a tendency to catch up with Japan and the United States, although China only produced the first crawler hydraulic press in 1964.
But after that, China's machinery industry has been seeking progress and development, and in 1995, some Chinese and Japanese companies began to cooperate, such as Komatsu and Hitachi Construction Machinery.
Among them, Komatsu Group has given a lot of technical help to our country, solved the problems encountered in technology, cultivated Chinese fundamentally to learn technology, and left a strong color on the blueprint for the development of heavy industry in china.
In return, China has opened its huge market to Japan, and China's vast products and resources are quite abundant, so most of Japan's industrial products are digested by China, which has such a high sales share in Japan.
It is no exaggeration to say that Japan's machinery industry is inseparable from China.
Although foreign countries monopolize the core technology, domestic brands are slowly developing and breaking them one by one.
In 2000, China's domestic excavator market share accounted for only five percent of the total market, and China could only manufacture small excavators.
In 2008, China's Sany Heavy Industry took the lead in breaking out of the technical barriers of foreign manufacturing and independently produced China's first domestically produced 200-ton crawler hydraulic excavator.
While breaking the monopoly of technology, it also helps many domestic enterprises to solve technical problems, and Sany Heavy Industry excavators will become the world's first in 2021. The goal of being the world's first has been officially achieved.
epilogue
Although the current achievements of China's mechanical construction engineering are gratifying, but we always have to remain modest, Japanese mechanical engineering as China's first teacher, we from catching up to slowly surpassing, good teachers and friends are vividly reflected.
Whether it is China's Sany Heavy Industry or XCMG Group, as a domestic brand, they will face various pressures at the beginning of their start, but they eventually resist this pressure, and slowly grow, constantly break through various technical barriers, and slowly become the leader in the industry.
Not only has the world witnessed the rise of China, but also become a national brand and a national pride.
The rise of domestic excavators is a microcosm of the history of China's mechanical engineering.
We have gone from decline to prosperity, and only those who have experienced the hardships can know, and China will definitely return to the top of the world in the future.
