Most of the excavators you don't know
As we all know, the Guinness world record is the most important part of the world. In the excavator industry, there are also many of the most engineering machinery. How much do you know about it?
1. The oldest excavator
In 1950, the first hydraulic excavator is hydraulic technology of aircraft and machine tools, and lacks of hydraulic components suitable for various working conditions of excavators. The manufacturing quality is not stable enough, and the supporting parts are not complete.
2, the largest shovel type excavator in China - the WK-75 excavator of Shanxi Tai heavy group
Heavy group self-developed WK-75 mine developed shovel is really a huge monster, from the track to the top more than 20 meters high, moving up the momentum of the earth trembled and the mountains swayed. The excavator is the largest, most technically advanced and productive mining excavator in the world, with a total weight of nearly 2000 tons, up to 23.5 meters, with a total length of 37.5 meters and a width of 17.3 meters. If it is dismantled, it will take 40 sections of the train to carry it off once. The big guy "weighty", it can dig a bucket weighing 135 tons of materials. Its spirit activity is not inferior to the other functions, such as excavating, turning, walking, turning, climbing and so on. The excavator and the same size self shifting crushing station support coal mining. The capacity of mining can reach 12000 tons per hour, and 5 million tons of coal can be produced in a month, which is equivalent to the output of a large coal mine in one year.
Hydraulic excavator Terex excavator -O&KRH400 3 -- the United States and the largest in the world
Since 1960s, hydraulic excavators have entered the stage of promotion and vigorous development, and the production of excavators and varieties in various countries have increased rapidly and the output has increased rapidly. In the past 1968-1970 years, the output of hydraulic excavators has accounted for 83% of the total output of the excavator, which is now close to 100%.
O&KRH400 shovel excavator is the largest hydraulic excavator in the world. It is the only 1000 ton hydraulic excavator at present. So far, only 6 RH400 have been put into use, of which 5 are used in the United States and 1 in mines in Canada, with only a positive shovel. The first RH400 was made in 1997, and the improved sixth RH400 was launched in 2002. The capacity of the tank is 16000L, the output power of the engine is up to 3280kW, and the positive shovel can hold 85 tons of mineral.
4, the world's largest electric excavator - American P&H5700 excavator
The 5700 series was launched in 1991, produced a total of 5 units, is the largest excavator model P&H company produced, the input voltage is 14400V, it is equipped with 4 bucket lift motor, 2 motors and 4 sets of rotary motor, the arm length is 21m, weight: 1667 tons, installed power: 9975kW bucket capacity: 61m3.
5, the world's largest bucket wheel excavator - German Krupp excavator KRUPP293
The ability of KRUPP293 is amazing. Even in the face of the most difficult to peel tight dense hard rock or frozen soil, the actual production capacity can reach 240 thousand m3/ days, especially the ability of excavation pine has reached an unprecedented 300 thousand m3/ days. From 293 of the main technical parameters, it has surpassed the first 288 of the first machine, which was put into use in 1978, and became the real king of the excavator.
6, the largest hydraulic excavator in China - the ZOOMLION ZE3000ELS super large hydraulic excavator
ZOOMLION ZE3000ElS super large hydraulic excavator is the largest tonnage hydraulic excavator in China at present. It fills the gap of the domestic super large hydraulic excavator. The performance of the whole machine has reached the international advanced level and the leading level in the country. It has broken the monopoly situation of the excavator product for a long time and has raised the status of the national brand. The operation conditions of the super large hydraulic excavator, the coupling of mechanical and electrical properties, the complexity of large system and multivariable, decide a series of important problems in the design and manufacture of super large hydraulic excavator.
The world of these excavators, the world's most, not only has a huge body, its real work is also amazing. This is the crystallization of human intelligence and the symbol of the progress of human civilization. As they devote themselves to construction, human life on the earth will be more comfortable and convenient.
