黑龙江工程学院本科生毕业设计附录A In the development of high-altitude operation truck Aerial vehicles in China in the 1970s did not begin to develop, a late start, compared to a whole than in other countries 30 years later, after 30 years, our dedicated aerial vehicle developed rapidly and has become an important economic development in the transport and operating equipment, widely used in electricity, street lights, municipal, landscape, communications, airports, making (repair) ship, transport, advertising, photography and other high-altitude operational areas. For now, China can only produce 60,000 meters, 10 meters, 14 meters, 16 meters, 18 meters, 22 meters, 25 meters, 30 meters and other high-altitude operation truck, recently, special vehicles Co., Ltd. Xuzhou independent research and development 33 m mixed arm Aerial first prototype come out. China-made car to achieve a maximum height of aerial vehicles, breaking the foreign arm of 30 meters above the mixed aerial vehicles monopoly, to fill the gap. But overall, Chinas relevant foreign private car or with a certain gap, reason, in addition to a late start, an important reason is the existence of special vehicle manufacturing plant scattered, chaotic, poor, the domestic private car Most plants are purchased chassis modifications for the production of small plants, low level of mechanization, workshop-style hand many products of varying quality; in the production technology and equipment, due to the lack of scale transformation, artistic workers low, limiting the products to improve the quality and grade, which restricts the development of a dedicated vehicle. Most of the foreign substance is a special automobile plant assembly plant. According to the structure of its products division or organization of production specialization and cooperation, such as trailer axles, fifth wheel, support Tim, suspension, etc., tank truck, construction vehicles, special equipment etc key focus by professional plant production. Such as Japan, Kato Seisakusho Ibaraki Plant assume only two design and assembly work, all parts by 32 professional-processing available. Kato only 500 employees, annual output of lifting vehicles up to 3000 3500. East of God 230 company employees, annual output of the charter, special vehicles 12,000. Foreign (especially Japanese) manufacturers strict division of labor, specialization of each component requires to ensure the quality of each component and high-tech, and domestic manufacturers, most parts are their own production, quality and science and technology can not be compared with other countries. Although the product has some advantages on cost, but definitely not a single low-cost dedicated car industrys future development of the weapon and to improve the technological content of products is the only way, otherwise we can only wasted resources, and produce a small amount of added value . Made in China can not become synonymous with low quality. In addition there are special car production market confusion, poor supervision of the problem, some of the qualifications of small factories do not produce, the price advantage of using the modified car with the big manufacturers undercut the national special vehicle led to the current market, there is a strange phenomenon, a number of qualified enterprises to hungry or not a job, such as semi-trailer production in Shanxi province with less than 10 qualified companies, but companies are manufacturing semi-trailer are around in the seventies and eighties; Shandong, a special vehicle production base, with 126 vehicles, tuning, less than 20 procedures for legitimate businesses. These qualifications do not produce small plants, on the one hand, there are many products produced by the defect, a securitys risk, but also disrupt the normal market, the impact of the development of special vehicles. These non-standard vehicles to enter the market will lead to serious consequences, the light of the high cost of repairs to customers and inviting, a major brewing severe accident.This lesson is not sensational. Chinas aerial vehicles (also including other special-purpose vehicles) in the general direction of development is good, both technically and development environment, we all hope he is a growing industry, the technical level to follow up even more than abroad, go abroad, accounting for foreign markets.In addition to our own research and development to focus on technology, but also create a good business environment. Not to the immediate interests of vicious competition. Government should take measures to come out and ban those who are not qualified small business, not a place for the so-called performance and deregulation. 附录B 发展中的高空作业车高空作业车在我国于70年代未开始发展起来,起步较晚，较国外比起来整整晚 了30多年，经过30余年，我国高空作业专用汽车发展很快，已成为经济建设中的重要运输 与作业装备，广泛用于电力、路灯、市政、园林、通信、机场、造（修）船、交通、广告、 摄影等高空作业领域。就目前而言国内只能生产6米、10米、14米、16米、18米、22米、 25米、30米等高度的高空作业车、日前，徐州专用车辆股份有限公司自主研发的33米混合 臂高空作业车第一台样机问世。该车达到了国产高空作业
