Large machinery and evolutionary images are common in science fiction movies, such as the Transformers series, Afanda and Star Wars. These films advocate mechanical strength and dominate everything. Machinery is pushed onto the altar.
There is such a big Mac machine in reality. According to the daily mail, the world's largest excavator appears in the world's largest coal mine, the Bogatyr coal mine, near the city of Kazakhstan. This bucket wheel excavator is manufactured by ThyssenKrupp, the predecessor of Thyssen Krupp Steel (Krupp), now in Germany. (Steel)
On a general construction site, a large excavator with a total weight of more than 30 tons has been difficult to see, and the weight of the giant bucket excavator is generally about 1500 times the weight of a large excavator.
Although the bucket wheel excavator is huge in size, it has wonderful installations and exquisite design, and has installed huge revolving wheels in its front. The diameter of the saws in the rotary wheel is 12 meters. The outer edge of the machine is a series of barrel shaped devices, which can complete the loading and unloading of coal through the conveyor belt. Most of the walking devices are crawler, and a few are walking.
Alexander Popov, a Russian photographer who took these photos, told the daily mail, "I've seen a lot of powerful machinery in the past, but it has never been seen so much."
The data show that the bucket wheel excavator is a multi bucket excavator which is continuously excavated by multiple shovels mounted on the front wheel of the arm. It has many advantages, such as large production capacity, high efficiency, easy operation, easy operation, easy maintenance and modern management in the complex coal seam. It is widely used in the developed countries in the world. Large projects usually used for large mining and long service life are suitable for open-pit mines and large earthworks.
The multi bucket excavator is a kind of bucket wheel excavator with high efficiency and high mechanization developed in the past twenty or thirty years. Productivity ranges from tens of cubic meters to tens of thousands of cubic meters per hour.
The manufacturers of multi bucket excavators include the Thyssen Krupp CPE of Germany and the American company of CPE. The product data show that the D-2500 multi wheel bucket excavator produced by CPE company in the United States is 150 tons, 1789.68 Watt, and 2500 cubic meters per hour can be excavated, equivalent to the workload of 10 thousand workers.
The British Post reported that the bucket excavator has a strong ability to work and excavate 4500 tons of coal every hour, clearing all obstacles ahead.
Of course, it will cost a lot to produce such a machine. It will cost about 66 million pounds (about 621 million yuan). The whole machine needs 27 miners to work together. Because of its huge size and slow action, it can only advance 1600 meters every 3 hours.
As the German philosopher Walter Benjamin said, the reason why machinery is beautiful is not only because of its utility, but also, it is more important that it satisfies the emotional projection of the mechanical power to people in the psychological level. This is the power of violence aesthetics.
The word "Violence Aesthetics" first originated from the Hongkong director Johnwoo film in China, which pointed out that he added the elements of music, flying feathers and white pigeons in the violent scenes filled with bullets and smoke, which made the picture strong Wu's style and unique beauty. The same is true for the violence aesthetics of engineering machinery: simple and brutal but full of strength, subverting our senses with an alternative beauty.
