problems and development prospects of China's construction machinery accessories industry

China's construction machinery information

Guide: at present, China's construction machinery industry is in a high-level operation stage, and construction machinery enterprises show a thriving situation. However, accessories are like a rope around the neck of enterprises, making it difficult for them to sleep and eat. Recently, I visited Ma Chuanwei, Secretary General of the construction machinery accessories Branch of China Construction Machinery Industry Association

at present, China's construction machinery industry is in a high-level operation stage, and construction machinery enterprises have shown a thriving situation. However, supporting parts are like a rope around the neck of enterprises, making it difficult for them to sleep and eat. Recently, I visited Ma Chuanwei, Secretary General of the construction machinery accessories Branch of China Construction Machinery Industry Association, and asked him to talk about the current problems in China's construction machinery accessories industry and analyze its development prospects

At present, China's construction machinery, especially small construction machinery, has broad market prospects. The market for small excavation is very clear. It is expected that by the end of the eleventh five year plan, the market demand for small excavation may reach 50000 units. In addition, small construction machinery markets such as lift and retract arm forklifts, skid steer loaders, and two busy are also in the process of cultivation and will have great development. But so far, the pumps, valves, hydraulic parts and other supporting parts required by small construction machinery basically rely on imports. Foreign accessory enterprises should first meet the needs of their domestic enterprises, second meet the needs of foreign-funded enterprises in China, and third consider the needs of domestic enterprises. This situation will have a more and more obvious restrictive effect on China's construction machinery production enterprises. This year, China's construction machinery enterprises, such as Hefei Zhenyu, failed to take delivery of goods after paying money to foreign accessory enterprises for up to one and a half years; If everything is installed, just wait for a valve, but Japanese enterprises are unable to supply it, such as Yuchai Machinery; Last year, Xu dug machinery ordered from Japanese enterprises at the beginning of the year, but it was still not delivered at the end of the year, resulting in zero output of excavators. Not only the delivery period cannot be guaranteed, but also the price of a full set of hydraulic systems purchased from abroad is generally not negotiable; In addition, factors such as inadequate pre-sales and after-sales services have greatly restricted the development of domestic construction machinery enterprises

choose a breakthrough

in view of the overall development level of China's construction machinery and the current specific situation, Ma Chuanwei suggested that small excavation and other small construction machinery accessories should be taken as a breakthrough to promote the overall development of China's construction machinery accessories industry

at the just concluded 2007 Ningbo China Construction machinery accessories industry annual meeting, Ma Chuanwei and the relevant person in charge of the accessories Branch suggested that manufacturers should pay attention to other small construction machinery accessories instead of just focusing on small excavation accessories, and take small excavation accessories as a breakthrough to drive the all-round development of other small construction machinery accessories

in order to realize the all-round development of small construction machinery accessories, including small excavation, the realization of its hydrostatic transmission is an important link. At present, the hydraulic pressure parts required for supporting small construction machinery, such as small wheel loaders, backhoe loaders (200 plastic bags are used per capita in the two EU Member States every year), sliding steering loaders, telescopic boom fork loaders, and small tonnage forklifts with hydrostatic transmission, are mostly imported. Internationally, the loaders of less than 3.0 tons in advanced countries are large, so in the process of purchase, they will give priority to some brands with relatively high prices to realize hydrostatic transmission, while the loaders with an annual output of more than 100000 units in China are almost all hydraulic transmission. At present, Shandong Longtai is the only domestic enterprise that can produce hydrostatic transmission accessories with the new construction or expansion of biodegradable plastic projects. This private enterprise can produce hydrostatic transmission loaders with a capacity of less than 3.0 tons, but it is only beginning production, which is not mature, and the production is still complete

in addition to the restrictive factor of key technology, Ma Chuanwei believes that another important aspect of the gap between Chinese construction machinery accessories and foreign products lies in their reliability. Small batch production of ten or eight pieces is reliable, but a large quantity is unreliable. The reliability of products is related to management, process equipment and process route. In general, at present, the main factors affecting the reliability of accessories in China are the quality of raw materials, especially steel. Domestic construction machinery enterprises are generally not large-scale, and they ask for special purchases from steel mills, which others ignore. There is also a gap in technology and equipment with foreign countries. Foreign countries have flexible production lines, and each procedure is strictly controlled. There are also problems in heat treatment. In this way, the reliability of the produced accessories is not good, which leads to the inability to improve the quality of the host. For example, the construction machinery products produced by foreign enterprises generally fail for the first time in 1000 hours, while our products only have 400 or 500 hours. If the reliability problem is not solved, even if it is sold cheaply, users will not buy it
