Economic trends and the development of real estate industry development trend crane industry has a certain scientific significance. In 2010, the Chinese economy continued the recovery in 2009 since the good momentum for the development of various industries laid a good foundation, bulldozer hydraulic cylinder along with the rapid recovery in the real estate industry, crane industry also has increased significantly, according to the China Construction Machinery Association statistics, in 2010 the tower crane sales exceeding 4 million units. 2011 by the real estate regulation, motor car accident, the Japanese earthquake and other factors, hydrostatic driven dozer the crane market expansion has slowed, but remained more than 10% growth rate.
In the 21st century, Swamp crawler dozer the overall pattern of China's crane industry has undergone great changes. There are always new companies to enter the tower crane industry, hydrostatic driven dozer it is estimated that China has more than 400 tower crane manufacturing enterprises (including enterprises above designated size has more than one hundred)
Chinese crane industry from the operation of contrast with the real estate investment analysis, swamp hydraulic crawler dozer crane industry has the characteristics of leading indicators for the real estate industry, changes in real estate investment in the crane industry a year in advance is displayed. Therefore, based on the current domestic and international economic situation, combined 2003--2011 development of China tower crane market, industry sales revenue in 2012 is expected to be close to 19 billion yuan, high driven bulldozer an increase of about 10%, slightly down compared with 2011.
Although prime rate canceled, Tractor bulldozer raise the down payment, the purchase and other factors will continue to plague the real estate industry in 2012, but considering the position the next time the real estate industry as a pillar industry of the unshakable, strong demand for real estate market rigidities and other factors, is expected to 2012 real estate industry is still on the rise, Mechanical Drive Crawler Bulldozer the protection of housing construction will become an engine for development.
Front and rear guide wheel high driven bulldozers drive sprocket and walking system triangular arrangement, the drive sprocket set away from the high ground, to avoid the traditional bulldozer contact with the ground due to the drive sprocket suffered a direct impact load, so that the drive significantly improve the life of the system. mechanically driven bulldozer is doing the best global Caterpillar, currently the only Vision Engineering technology is mature and has formed a production. Vision Engineering since 1993 to develop and produce high drive bulldozer, 2003 batch to domestic and foreign markets, there are SD7 (230HP), SD8B (320HP), SD9 (430HP) 3 major product lines.
After the 20th century, after 30 years, with the continuous progress of science and technology, bulldozer hydraulic cylinder motorcycle production and use of the suspension shock absorber system, mechanical ignition system, mechanical drum brakes, chain drive, so that the motorcycle has climbed to new stairs, motorcycles gradually mature, Mechanical Transmission dozer widely used in transportation, competition and military aspects. This is the third stage of the motorcycle - maturity.
Composition and working principle of hydraulic and electrical systems bulldozers bulldozers knowledge of safe operation and maintenance of knowledge, typehydrostatically drive crawler tractor, the overall structure and application, bulldozers major component structure and working principle parts, bulldozer common failure modes and causes of failure,Hydrostatic bulldozer knowledge of other typical form bulldozer damage and repair methods bulldozer wearing parts
