In order to safeguard their national sovereignty and territorial integrity, all countries in the world are seeking near-perfect power in the military field while not developing their economy. But no matter in which field or thing there is no near perfection. If you want to achieve higher achievements, you must face greater difficulties. For example, the super weapon aircraft carrier in the military field at this stage, as the rarest military force with one of the few combat strengths, has become a symbol of a country's comprehensive strength. .

u3000u3000 But because of the high technical difficulty of building aircraft carriers and the cumbersome construction process, so far there are very few countries that have aircraft carriers. As the second largest aircraft carrier country in the world, China not only possesses the technology to build aircraft carriers, but also masters a core technology of heavy equipment that can hold the lifeline of aircraft carrier construction. Foreign experts have asserted that without it, countries in the world will no longer build aircraft carriers. It is China's gantry crane technology, so what kind of supernatural power does the gantry crane have that allows foreign experts to give such a high evaluation?

In terms of gantry crane technology, China is definitely the number one in the world, and it has even become popular in the West. Even the American and British aircraft carriers must come to buy domestic gantry cranes, which can be said to have made enough American money, but even Zhenhua The maximum lifting tonnage of the gantry crane is only 2,000 tons, but now there is a gantry crane that can lift 20,000 tons of heavy objects at one time! Do you dare to believe it? It is the Honghai gantry crane. This large country heavy equipment is as high as 50 stories. Is there only China in the world that can achieve this tonnage gantry crane?

u3000u3000 According to reason, the development of gantry cranes is not that difficult, that is, the principle of ordinary cranes, and large gantry cranes can be seen in ports and shipyards in various countries. Why is this technology now monopolized by China? The development of gantry cranes is indeed not difficult, and it has always been a patent of Western countries before, but since Western countries have transferred their industries, they believe that the shipbuilding industry related to gantry cranes is a high energy consumption and labor-intensive industry, so they have been transferred to developing countries. , China has seized the opportunity and successfully developed into a leading enterprise of gantry cranes. If foreign countries want to buy gantry cranes, they can only order from China.

Although the technology of gantry crane seems to be uncomplicated, it involves many disciplines such as steel smelting, structural mechanics, mechanics, etc. Western countries have been abandoned in the field of gantry crane technology for more than 20 years, and a technical fault has long been formed, and it wants to resume manufacturing. Small gantry cranes may not have any problems, but if you want to build a thousand-ton gantry crane in one go, it is estimated to be choking, and the foreign gantry crane market is very limited. Take the United Kingdom as an example. After the aircraft carrier was built, the gantry crane lost its value in the United Kingdom. In order to recover the cost, the country immediately transferred the gantry crane to India.

It is conceivable that even if other countries are willing to work hard to resume the development of gantry cranes, they will eventually fail due to insufficient market, not to mention that in the international market, there is a strong competitor, China, if Western countries want to develop their own Gantry crane, doesn't that mean you are looking for a dead end? Therefore, Western countries that are slightly more sober would never think of competing with China in the field of gantry crane technology, which directly contributed to the dominance of domestic gantry cranes.

u3000u3000 The Honghai gantry crane that was born now has a lifting tonnage of 20,000 tons. Even if it is to build an aircraft carrier, it does not need such a large gantry crane. So why does China need to develop it? To know what is the concept of 20,000 tons, the Chinese Navy's Type 055 million ton destroyer, if it is just leaving the factory, then this gantry crane can lift two 055 at one time. With this giant gantry crane, China can even do it without a dock. Large ships are directly built, and in addition to shipbuilding, China is also developing large offshore drilling platforms, and the development of these equipment requires gantry cranes to play an important role.

  development path

u3000u3000 Speaking of the development of gantry cranes, one thing I have to say is that China is not the first country to conduct research and production of gantry cranes. In fact, Europe and the United States and other countries have carried out the production and research of gantry cranes a long time ago, but then all countries without exception gave up this project that they thought was a sunset industry. However, China saw an opportunity for development in it. Since the beginning of the 20th century, all countries in the world have been building ports, and a large number of ports have sprung up like bamboo shoots after a rain. In this process, the functions of gantry cranes became apparent. Due to the low labor cost in our country at that time, the gantry crane industry began to flourish in our country.

u3000u3000 Until recent years, my country's gantry crane industry and related technical fields have been advancing by leaps and bounds. Speaking of this, Xiaoli would like to thank the Western powers because they directly created the status quo of the gantry crane industry and technology in my country. Why do you say that? Because in the 1950s, the economic development of countries around the world was in good shape. China's development momentum is particularly strong. At this time, the Western powers were afraid of the outflow of advanced technology that would make China stronger, so they implemented a comprehensive blockade of technology. What should I do if I have no skills? Production cannot be stagnated because of lack of technology.

u3000u3000 At this time, tens of thousands of industry technical experts began to study the technology with great concentration. They overcome all difficulties and worked arduously. After decades of research, they finally developed a world-leading technology. Facing such a situation, some countries and regimes in the world are certainly not convinced. They began to slander China's gantry crane technology. But for a while, I couldn't find other technologies to replace the gantry crane technology in our country, and could only wander back and forth in this state of love and hate. Then, is the technical content of the gantry crane in our country like they said?

u3000u3000 Research is not as good as import

u3000u3000 In fact, the technical content of the gantry crane is not too high in terms of its appearance, structure and working principle. The highest technical content should be its precise core part, which means that the core technology should be the instrument and the programmable controller. So why do countries in the world do not produce by themselves but rely on China's imports? First: market issues. Looking at the world, the large market for gantry cranes is in China, and China has the largest number of ports and offshore construction platforms. For gantry cranes, my country already has a huge internal digestion market. The production of gantry cranes is only used for the domestic market, and the quantity is basically saturated. In order not to be restricted by other countries, it is very necessary for my country to carry out technological research and development. . Let's take a look at other countries. Even if we overcome the technical difficulties of the gantry crane, the main profit direction will only be export. If a competitive opponent appears or is directly restricted from import, then this technology will be stranded.

u3000u3000Second: Cost reasons. Gantry crane can be regarded as a good large-scale equipment among many large-scale equipment. Called a Big Mac. Therefore, in the production process, a high cost of manpower, material resources and financial resources will be invested. For Western countries where the market is relatively scarce, such a large input cost is undoubtedly angel investment, and the probability of loss will be very high. Not only that, the production chain of gantry cranes in western countries is much more expensive than the industrial chain of our country. Third: quality issues. Although we have said earlier that the technical content of some parts of the gantry crane is not very high, and the gantry crane seems to be low in technical content, but the production process is very complicated. It does not mean that the technology is not high and whoever wants to build it. Faced with this kind of quality problem, it is not as convenient to make it yourself as it is to buy it. The first thing you buy is the world's advanced quality level, and the second is that it can save costs.

u3000u3000 At the point of the quality of the gantry crane, there have also been hilarious farce. According to legend, India encountered a bottleneck when it was preparing to build its own aircraft carrier a few years ago. They did not have a gantry crane capable of building an aircraft carrier. However, the political situation in China and India was very tense at that time. They thought, come to China to buy it at this time. Gantry cranes are definitely not good, and they can't bring them such a large economic income. To put it bluntly, I don’t want to buy equipment from our country. The Indian side finally bought a second-hand gantry crane in the hands of the United Kingdom. Later, when India started to produce their aircraft carriers, they discovered that the gantry crane was also a Chinese product. Moreover, the investment spent on second-hand goods is much greater than that of direct import in China. This is really a very loud fight.

u3000u3000 With the continuous development of China's gantry crane technology, the world's major countries are both envious and fearful. What I envy is that we can overcome such a big problem, create one miracle after another, and promote the development of human society. The fear is that once there is a political conflict one day, all countries in the world will face stagnation in production in this field. It is the legendary choking of the development of the industry. What Xiaoli wants to say here is that China has been following the principle of peace and common development since ancient times. As long as countries in the world do not easily create friction, we are still relatively hospitable. Once someone provokes us, we will never condone and will fight back. ,
