Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an important role in the world, and to promote the progress of civilization, technology has made great contribution to Chinese traditional machine. And in a long period ahead in the world. In modern times, especially from the early 18th century, due to the nineteen forties, due to the economic and social reasons, such as the China machinery industry, stagnation, in the 100 years is western bourgeois political revolution and industrial revolution, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level and the western gap widens, sharply to the 19th century middle behind western one hundred years.After the founding of new China, especially in the past 30 years, our countrys mechanical science and technology development speed. To the mechanical product large-scale, precision, automation and discusses the trend of development. In some aspects has reached or exceeded the world advanced level. Generally speaking, currently China mechanical science and technology achievement is huge, developing fast, high level of unprecedented. In this period, China has no end of mechanical science and technology will develop to a higher level. As long as we can adopt the correct policy, with good technology development and innovation, our machinery industry and mechanical technology can revitalize, leading to the development trend of mechanical industry.（1）Just small ramming machinery:In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial ramming.Early 1960s, changsha construction machinery institute and Beijing architectural engineering institute, etc., the technical innovation achievements in mass on the basis of summing up Chinese characteristic invented the breaststroke ramming machine, 1962 exceeded national science and technology. The breaststroke ramming machine structure is simple, easy to use and maintenance in 1960s, soon became the dominant products to consolidate machinery. According to not complete count breaststroke tamp cumulative yield reached more than 50,000 machine, in the economic development of our country has played an important role. Since 1970s, the breaststroke ramming machine was gradually more advanced performance of vibration shock ram and vibrating plate ram, now replaced by laying machine has rarely breaststroke, basically be eliminated.In 1964, changsha construction machinery institute HB120 developed movable type, type of Shanghai began laying machine, engineering machine production mainly by Tianjin municipal later, annual production engineering machinery dongting about 200. In the 1980s, movable type ramming machine product quality has increased greatly, have exported to southeast Asia and Africa. Since 1990s, internal-combustion type ramming machine production sales, and gradually decreased in only a few small private enterprise production.In 1977, changsha construction machinery factory buildings and developed in liuzhou HZR250 type and the HZR70 type vibrating plate ram, these two kinds of products in 1979 and 1982 passed by the ministry of construction of the organization. Then yiwu building construction machinery factory, siping, anyang vibrators factory, Tianjin municipal engineering machinery dongting and other enterprises have started producing vibrating plate ram.
