The development of Concrete machinery
Before the reform and opening up, the concrete used in the construction site of our country was mainly used in the field stirring, and the equipment used was a drum shaped mixer with poor mixing quality and low efficiency. In 1978 China's only production mixing building (station) 13, mixing truck 10, concrete pump (car) 22, and the product performance, quality and reliability are poor, far cannot meet the needs of the construction unit, therefore had to rely on imports. At the peak of 1995, there were 1,745 imported agitator trucks, and the total amount of imported concrete machinery was $220 million, double the sales of domestic concrete machinery.
After more than 30 years of development, China's concrete machinery industry has developed rapidly. In 2009, the total assets of the industry totaled 44173 million yuan, up 31.97 percent year on year. In 2010, the total assets in the industry totaled 68473 million yuan, up 55.01 percent year on year. In the first half of 2010, the sales volume of concrete machinery reached 506 million, and the task of the whole year of 2009 was completed in half a year, with a year-on-year growth of 130 percent, and the exclusive engineering machinery industry. In the second half of 2010, although the pace of development was revised, it was still a rapid growth, with annual sales exceeding 90 billion yuan, which doubled in 2009. In the concrete machinery industry, zhonglian and one or two companies, the two companies accounted for about 40 percent of the total concrete machinery sales in 2009, and basically maintained that level in 2010.
There are 121 enterprises in the size of concrete machinery industry in China, which have formed a multi-series and multi-breed specifications. Whether (floor) mixer, mixing station, mixing truck or concrete pump (pump truck) and other products, in addition to the large and high technology content model, normal product has been basically can meet the needs of the construction. The production conditions of each manufacturer are generally improved and the production capacity is further enhanced. The import quantity of foreign concrete machinery has been decreasing year by year, and the domestic equipment has dominated.
With the development of concrete mechanical technology, the application of concrete machinery is becoming more and more extensive. Concrete machinery products are mainly used in highway construction, railway construction, real estate, construction, power infrastructure construction, rail traffic infrastructure construction and other fields, the product performance must meet the needs of the construction industry. The influence of downstream industry on concrete machinery industry is mainly in market demand and market competition. The development of the concrete machinery industry relies on the pull of the downstream industry, which also restricts the development of these industries.
Concrete machinery mainly includes the concrete pump truck, concrete pump (pump, car pump), concrete mixing station, concrete mixer truck, and placing boom, etc., which belongs to the pump car and mixing proportion is the largest. The quantity of concrete mixer in China is about 240,000, and the number of pump vehicles is about 30,000. All of 2012 concrete mixer truck sales of about 85800 units, year-on-year growth of 26.21% year-on-year, pump truck sales of about 11800 units, year-on-year growth of 17.6% year-on-year, growth rates have declined in 2011.
