2 markets structure: The tide since tide of all previous classics falls, prices be pregnant has concern
Squeezing ramming machinery occupies proportion of sale of machine of our country project to make an appointment with 5%~6% . Homebred roller all along is the brunt on home market, and there also is certain competition ability on the international market. But market small blown away by wind of nearly two years, make squeezing ramming machinery is made also step forward dimension difficult, economic benefits considerably shrink.
March toward peak 3 2.1 years, slide two years trough
Domestic roller crop is added from 6122 of 2000 to 2003 12941, average year of amplitude 28.3% . The total sales volume of the roller on Chinese market also adds 12801 of 2003 from 5966 of 2000, average year of amplitude 29% . China already became the world to go up most the roller production nation that reach and consumptive market, the total sales volume of Chinese market exceeded North America far 2003 (8200) , Western Europe (9100) with Japan (1500) .
The country implemented policy of macroscopical adjusting control 2004, project machine market is successive 3 years " blowout " be restrained. Be the first to be affected of squeezing ramming machinery, roller trade sales volume glides all the way, decline from 12941 of 2003 8623 of 2005, drop 33.4% . Delectable is 2006 the industry already walked out of trough, the roller total sales volume of domestic company promoted 9% , the total sales volume of foreign capital enterprise makes an appointment with 800, the total sales volume of countrywide roller approachs 10 thousand to close greatly again.
Dominant of 2.2 low product, multiple market coexists
The roller of developed country of 60 time industry basically realized 20 centuries complete hydraulic pressure is changed. Our country begins to introduce roller of vibration of complete hydraulic pressure from 80 time, but home is being made, in use and maintaining a course, because be opposite of fluid drive technology not close and appeared a certain number of incommensurate, bring about manufacturer to must be on conventional mechanical drive thereby move scheming. The course introduces the engraft of technology and traditional technique, was born in China the tire drive of mechanical drive is single round of oscillatory roller.
The oscillatory roller of mechanical drive and static grind roller, mature as a result of opposite technology and cheap and fine, and run cost low, approbate generally in what home acquired an user. The roller of domestic mechanical drive (contain static grind and oscillatory) the 80% above that take roller total sales volume for years continuously. Roller of our mechanical drive vibration still got the favour of a few developing countries and area user. Appeared in China then roller of roller of vibration of complete hydraulic pressure, mechanical drive vibration and product of former outfit entrance are multiple the situation that the market coexists.
