Recently, JS8000 concrete mixer, independently developed by Zoomlion Concrete Machinery Company, was successfully installed in Zhongshou Hanshou Industrial Park and finished the whole machine assembly by the end of the month. Machine design is about 7 meters long, 3.4 meters wide, about 3 meters high, weighing 40 tons, a tank of concrete hydraulic tank capacity of 8, the mixer size and weight have reached the nation's most.
The successful installation of JS8000 mixer indicates that Zoomlion has mastered the overall welding technology of super-large mixer shell and the whole assembly process. The mixer size and weight of the country's largest, the largest processing size span of 5.6 meters, a single maximum lifting tonnage of ultra-20 tons, and both ends of a total of eight axial holes need to ensure a high degree of coaxiality and parallelism, front and rear shaft hole Concentricity error of not more than 0.1 mm, the existing processing and manufacturing equipment has been unable to meet the requirements, the need to use large-span heavy-duty manufacturing technology and large welding box manufacturing manufacturing technology.
According to the 12th Five-Year Plan of National Power, hydropower will become an important source of energetic development, which will bring a lot of procurement requirements for equipment including hydraulic concrete mixing buildings. However, the existing small amount of hydraulic concrete mixers on the market obviously Can not meet the huge market demand. JS8000 successful development, on the one hand, let our country become one of the few master super-large amount of concrete mixing technology countries; the other hand, the development of hydropower customers, expand the hydropower market and accelerate the development of China's water conservancy and hydropower infrastructure.
