China's aerial work machinery manufacturers started in the 1970s and have a history of more than 30 years. So far, domestic high-altitude machinery manufacturers have grown from more than 100 at the time to more than 100, of which 4 are joint ventures or cooperative production with foreign countries. Through the technical transformation in recent years, several key enterprises in the industry have continuously expanded their production scales, and they have formed a series of unique products. The main economic indicators of the company have gradually increased, and the economic benefits have been improved year by year, which can basically meet the domestic market. The needs of large, medium and small aerial work machinery, and some products are exported. According to the preliminary statistics of the member units of the association, the output of China's aerial work platform in 2005 was 1,734 units and 150 units were exported; in 2006, it was 1,890 units and 290 units were exported. In 2005, the output of aerial work vehicles was 672 units and 20 units were exported; in 2006, it was 778 units and exported 69 units. The preliminary statistics of the total output value of the aerial work machinery industry was 268.22 million yuan in 2005 and 326 million yuan in 2006. In the first half of 2007, the output value and export volume were close to the full year of 2006. Although domestic high-altitude machinery has developed rapidly in recent years, the development of enterprises is very uneven, and there is a big gap between enterprises. Therefore, it is of great significance to analyze and discuss the status quo of the industry and the development of products.

In recent years, the development of China's aerial work machinery is mainly reflected in the following aspects:

(1) The number of varieties is increasing.

Ten years ago, China's aerial work platform products were mainly scissor-type, sleeve-cylinder and other products, and the shift of products was mostly based on hand-push. With the development of the national economy and urban construction, the demand has increased year by year, and new products of various specifications have increased rapidly in recent years. For example, Beijing Jingcheng Heavy Industry Group has developed single-column aluminum alloy platform and double-column aluminum alloy platform, vehicle scissor platform, scissor self-propelled platform, boom platform and box-shaped aluminum alloy in just a few years. Nearly 10 varieties and more than 30 specifications of products such as mast platform and spider aerial work platform. Hangzhou Saiqi Aerial Work Machinery Co., Ltd. has developed single-column aluminum alloy platform, double-column aluminum alloy platform and multi-column aluminum alloy platform in recent years. The multi-column aluminum alloy platform has completed 10m, 12m and 14m. The development of 7 kinds of specifications such as 16m, 18m, 20m and 22m has completed the development of the vehicle-mounted aluminum alloy platform and the development of the self-propelled aluminum alloy platform and the explosion-proof aluminum alloy platform. Zhejiang Dingli Machinery Co., Ltd. has completed the development of self-propelled single-column and self-propelled double-column aluminum platform and scissor self-propelled platform. Hangzhou Aizhi Engineering Vehicle Co., Ltd. has developed a self-propelled aerial work platform driven by a full hydraulic chassis, providing new products for domestic ship repair, construction, airport and industrial and mining enterprises, and in just a few years. More than 10 series of aerial work vehicles have been developed, and insulated high-altitude work vehicles have been completed. Jinzhou Heavy Machinery Co., Ltd. has completed the development of high-altitude fire rescue vehicles of 22m, 32m and 50m in recent years. Xuzhou Heavy Machinery Co., Ltd. has completed the development of 22m, 24m, 32m, 40m, 53m and 68m high altitude high-altitude fire rescue vehicles. The above products were quickly put on the market to replace imported products.

(2) Product performance has been greatly improved.

China's aerial work machinery products have developed many new products through learning, introducing and digesting foreign advanced technologies. The technical level and product quality of their products are constantly improving, reaching and close to the level of similar international products, and they are highly competitive in the domestic market. The market is selling well and the output is increasing rapidly. For example, Beijing Jingcheng Heavy Industry Group has developed a scissor self-propelled platform and a box-section aluminum alloy mast platform. The maximum working height of the box-section aluminum alloy mast platform single mast is 16.5m; 22m, 25m and 30m are developed. Spider-type aerial work platform. Hangzhou Saiqi Aerial Work Machinery Co., Ltd. has reached 22m multi-column aluminum alloy platform, and developed an explosion-proof aluminum column platform and a self-propelled aluminum alloy platform. It has taken the lead in obtaining CE certification in domestic counterparts. The fully hydraulic chassis-driven self-propelled aerial work platform developed by Hangzhou Aizhi Engineering Vehicle Co., Ltd. has a maximum working height of 26.7m. The insulated high-altitude working vehicle has been developed, and the working bucket of the product has a withstand voltage of 20kV/5min. The inner lining withstand voltage is 50kV/5min, and the insulation arm withstand voltage can reach 100kV/1min. The above products have filled the blank of this type of products in China and reached the international advanced level. In addition, in the aerial work vehicle products, Hangzhou Aizhi Engineering Vehicle Co., Ltd., Jinzhou Heavy Machinery Co., Ltd., Xuzhou Heavy Machinery Co., Ltd. and Chongqing Dajiang Industry (Group) Co., Ltd. have developed high-altitude fire-fighting vehicles of more than 30m. Among them, Jinzhou Heavy Machinery Co., Ltd. completed the development of a 50m high-altitude fire rescue vehicle. Xuzhou Heavy Machinery Co., Ltd. completed the development of 53m and 68m high-altitude fire rescue vehicles, completely breaking the domestic situation that products above 30m can only rely on imports. .

(3) The market share has further expanded.

Some enterprises use their own advantages to continuously increase the development of new products based on the increase of domestic chassis types and the updating of some basic components on the basis of the original products, and take the comprehensive development road of horizontal integration of diversified operations. The company's own production and sales have entered a virtuous cycle, and it has also driven the sales of affiliated companies and domestic related companies. For example, Hangzhou Garden Machinery Factory has officially established a joint venture with Japan Aichi Co., Ltd. since the end of 1995. On the one hand, it has increased the upgrading of domestic products, and on the other hand, it has continuously developed products suitable for domestic users with the advanced technology and management experience of Japan. In the past few years, more than 10 new products have appeared and have a large market share in small and medium-sized work vehicles, and some products are exported. Xuzhou Heavy-duty and Jinzhou Heavy Machinery Co., Ltd. have developed a high-altitude fire-fighting operation vehicle of more than 30m for the weak situation of domestic large-scale fire rescue operation vehicles. It has been well received by domestic users and has achieved good economic benefits and society. benefit. Hangzhou Saiqi Aerial Work Machinery Co., Ltd. and Zhejiang Dingli Machinery Co., Ltd. have passed the European standard CE certification, and the performance and quality of the products have been continuously improved. In recent years, the export volume of products has been increasing. It can be said that the development of various products of the above-mentioned backbone enterprises can basically meet the needs of the domestic market, occupy a large share in the domestic market, and also have a place in the international market.

(4) Complementary advantages have promoted technological progress in the industry.

Some large and medium-sized enterprises in the domestic truck crane industry have developed many products in this industry in recent years by utilizing their own technological advantages and equipment advantages. For example, in 1996, Jinzhou Heavy Machinery Plant developed the highest altitude fire rescue vehicle with a height of 50m in China. Xuzhou Heavy Duty also developed 53m and 68m aerial work rescue vehicles. Beijing Jingcheng Heavy Industry Group has developed aluminum alloy mast series aerial work platform, self-propelled scissor platform and spider folding arm platform. The development of these enterprise products has promoted the development of technological progress in the industry.
