附 录 Present situation of access working vehicles industry and its development stratagem in ChinaOur work in the machinery production in the late 1970s, rapid development, started the current production management enterprise with several rapidly increased to over 40, and foreign joint ventures or cooperative enterprises have five production. According to 2004 and 2005the Chinese mechanical engineering yearbook，2003 annual aloft working machinery industrial output for 32139 million yuan, the production of various kinds of aerial work platform 1906, aerial work platform car 7.4, In 2004, aloft working machinery industrial output for 36340 million yuan, the production of various kinds of aerial work platform 2500, car 800 sets. In recent years, through several backbone enterprise industry technical transformation, the production scale expands unceasingly, formed the respective characteristics of the products can meet the domestic market # aerial work machinery need, its main economic index of enterprise economic benefits are rising gradually, increasing.1 Aloft working machinery industry development present situation 1.1 To improve product performanceOur aloft working machinery industry backbone enterprises of some use their equipment and technology advantages, through the study, the introduction and digest its own technology and equipment, through the study, introduce advanced foreign technology and developed many new products, the products of the technical level and product quality is improving, and close to the international similar product level # promoted aloft working machinery industry in the domestic market and technological progress in competitive and market demand, the yield increased rapidly. If Beijing hoisting machine factory developed self-traveling shear fork platform, the spider type folding boom platform, aluminum mast section of the box. One box type aluminum mast section of the largest single mast operation platform will reach the height of 16.5 m, Hangzhou and engineering machines more mast 22m reached alloy platform, hangzhou aichi engineering vehicles Co., LTD develop full hydraulic driving type self-traveling aerial work platform, the maximum height of 26.7 m homework. The above products fill the blank, domestic products have reached the international advanced level. In addition, in the car factory products, fushun crane, jinzhou heavy machinery Co., LTD, xuzhou construction machinery group and chongqing dajiang industrial (group) Co., LTD has developed over 30 aloft work, broken fire only depending on the imported products of domestic situation of the weak.1.2 Product category and quantity increasingOur work with the mechanical product demand of national economy and the development of urban construction increased year by year, all kinds of new products increased rapidly in recent years. If Beijing hoisting machine factory in just a few short years time successively developed car scissor platform, shear fork self-traveling platform, folding boom type platform, single mast aluminum alloy platform and double mast section aluminum box platform, aluminum mast platform, manual mast platform for nearly 10 varieties of products to more than 30 specifications. Hangzhous engineering machine developed in recent years has single mast aluminum alloy platform, mast platform and aluminum mast platform, aluminum mast completed 10m platform and 12m 14m 16m 18m, and seven kinds of specifications 22m were developed. Hangzhou aichi engineering vehicles Co., LTD has developed the self-traveling hydraulic drive aerial work platform for domestic shipping building, building, airport and mining enterprise of installation and maintenance, provides the new project. PuYuan group Co., LTD. Has developed 12m 16m, 30, and 20m 25m, car and QKH8-19-8 lifting and car. Jinzhou heavy machinery Co., LTD. In recent years has completed 22m, high altitude 32m 50m, big JiuYuanChe fire, xuzhou heavy machinery finished high altitude JiuYuanChe 67m big fire19.2 Aloft working machinery industry problems（1）Part of enterprise technology innovation ability is poorPart of the enterprise value product update and new product development, product decades of consistent, specifications, single market business enterprise product yield, narrow range declined year by year, industry benefits. In recent years, the work of mechanical products into the domestic, such as Finland, the United States JLG, Bronto company is well-established and Genin, Up Skyjack Snorkel, such as Britain, Italy, Denmark, some famous companies in China were successively established offices, and in the large and special products of high product main domestic markets, still holds such as aerial insulation car, spiders type high operation platform, self-traveling aerial work platform, etc. These imported products performance is good, beautiful appearance, price and domestic products, strong comp
