Hardware accessories industry market development prospects

Although the development of construction machinery is good, but China's machinery parts are dependent on imports, in order to meet the needs of China's machinery parts. At present, China's construction machinery industry is at a high stage of operation, construction machinery enterprises have shown a prosperous situation, however, the matching parts like a rope covering the neck of the company, so that it is difficult to eat. Recently, he visited the General Secretary of China Construction Machinery Industry Association's Engineering Machinery Components Sub-committee Ma Chuanwei and asked him to talk about the current problems in China's construction machinery parts industry and analyze the development prospects. Reliance on matching parts Currently, China's construction machinery, especially small construction machinery, has a broad market prospect, and the market for small digging is very clear. It is expected that by the end of the 11th five-year plan, the market demand for small digging may reach 50,000 units. In addition, the small-scale construction machinery market, such as boom-lift forklifts, skid-steer loaders, and busy-slots, will also undergo greater development during the cultivation process. But so far, the pumps, valves, hydraulic parts and other accessories required by small-scale construction machinery are all basically dependent on imports. The foreign partner companies must first meet the needs of their domestic companies, the second must satisfy the needs of foreign companies in China, and the third must take into account the needs of local Chinese companies. This situation will become more and more obvious to China's construction machinery manufacturers. This year, China's construction machinery companies have paid for foreign companies for up to a year and a half. They are still unable to get goods, such as Hefei Zhenyu; anything is installed, waiting for a valve, but the Japanese companies are late. Late supply, such as Yuchai Machinery; last year's Xu excavation machinery, orders to Japanese companies at the beginning of the year, the results did not give goods by the end of the year, leading to zero output of the excavator.

Not only can the delivery period not be guaranteed, but at the same time, the price of a full range of hydraulic systems purchased from foreign countries generally has no room for negotiation. In addition, factors such as pre-sales and after-sales services are not in place, which greatly restricts the development of domestic construction machinery enterprises. Choosing breakthroughs In view of the overall level of development of China's construction machinery and the current specific conditions, Ma Chuanwei suggested that small digging and other small construction machinery parts should be used as breakthroughs to promote the overall development of China's construction machinery parts industry. At the annual meeting of China Construction Machinery Fittings Industry, Ma Chuanwei and the relevant person in charge of the accessory branch recommended that manufacturers pay attention to focusing on small-sized digging parts and guiding them to take into account other small-sized construction machinery components, and use small digging parts as a breakthrough. , driving the full development of other small construction machinery parts. To realize the all-round development of small construction machinery accessories, including small digging, achieving its static pressure transmission is an important link. At present, the hydraulic components required for small-scale construction machinery, such as small wheel loaders, backhoe loaders (two busy), skid steer loaders, telehandlers, and small-tonnage forklift trucks, etc. Partly imported. Internationally, loaders under 3.0 tonnage in advanced countries have mostly achieved hydrostatic transmission, and almost 100 million loaders in China are hydraulic transmissions. At present, only Shandong Longtai, which is the only company capable of producing static pressure transmission parts, can produce hydrostatic transmission loaders below 3.0 tons. However, it is only still in production, and it is still immature and the production is still complete. In addition to the constraints of key technologies, Ma Chuanwei believes that another important aspect of the gap between China's construction machinery parts and foreign products lies in its reliability.

The production of ten or eight pieces in small batches is reliable, and if the quantity is more than one, it is not reliable. Product reliability is related to management, process equipment, and process routes. In general, the main factors affecting the reliability of China's fittings are raw materials, especially the quality of steel products. Domestic construction machinery enterprises are generally not large in size and require special purchases from steel mills. Others ignore them. There is also a gap between technology and equipment and foreign countries. There are flexible production lines abroad and each procedure has strict controls. There are also problems with heat treatment. The reliability of the kits produced in this way is not good, which leads to the inability of the host to improve its quality. If the construction machinery products produced by foreign companies are generally the first failure in 1000 hours, our products will only have 400, 500 hours. Reliability problems are not solved. Even if they are sold cheaper, users will not buy it. If we do this, the status quo of mechanical parts that I have passed will be greatly improved, the demand for imports will gradually decrease, and the rapid economic development of our country will be promoted.
