There are many factors affecting the development of the construction machinery parts industry, mainly raw materials, especially the quality of steel. In foreign countries, many construction machinery and equipment have developed into unimaginable huge sizes. At present, China's construction machinery industry is in a high-level operation stage, and construction machinery enterprises have shown a thriving situation. However, the matching parts are like a rope that covers the neck of the company, making it difficult for them to sleep.
Let's analyze the current problems and potential development prospects of the construction machinery parts industry. Construction machinery parts include power components, transmission components, hydraulic components and electrical components. In front of the engineering machinery power components basically use internal combustion diesel planning machine; transmission sub-mechanical transmission, hydraulic mechanical transmission, hydrostatic transmission, electric transmission and so on. However, the most widely used and most commonly used engineering machinery is hydraulic mechanical transmission and hydrostatic transmission. The entire transmission system also includes the drive shaft, drive axle and so on. Hydrostatic transmissions are available in a variety of structural formats, some with drive shafts, drive axles, and some, depending on the situation; hydraulic components require cylinders, pumps, valves, seals, and hydraulic accessories. Hydrostatic components of pumps, motors, and corresponding reducers; electrical components used to immerse the construction machinery is not large, the earliest engineering machinery parts mechanical electrical system, the start circuit and lighting circuit, system and components are very Simple, the start can be started by dragging, and there is no need to illuminate during the day. Therefore, if the two circuit systems fail, they can barely keep working.
However, the development of engineering machinery to today, electrical systems and electrical components has become a very important part of engineering machinery, it can be said that most of today's engineering machinery, electrical system failure can not work, and some even difficult to move, equal to one Pile of scrap steel. Therefore, the electrical system and electrical components are also one of the most important components of engineering machinery. In addition to the traditional components, there are various sensors, various components and micro-processors.
The market prospects are constrained by the formation of supporting parts. 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 digging may reach 50,000 units. In addition, the market for small construction machinery such as the forklift truck, the skid steer loader, and the two busy machines are also in the process of cultivating, and there will be great development. But so far, the pumps, valves, hydraulic parts and other supporting parts required for small construction machinery are basically all imported. The foreign supporting parts enterprises must first meet the needs of their domestic enterprises, the second must meet the needs of foreign-invested enterprises in China, and the third should consider the needs of local enterprises in China.
This situation will become more and more obvious for China's construction machinery manufacturers. In 2009, China's construction machinery enterprises have to pay foreign supporting parts enterprises. After a year and a half of money, I still can't get the goods; if everything is installed, I will wait for a valve, but the Japanese company will not be able to supply it; for example, a machinery company orders goods from Japanese companies at the beginning of the year. As a result, it was not delivered at the end of the year, resulting in zero output of the excavator. Not only the delivery period can not be guaranteed, at the same time, the price of a full set of hydraulic systems purchased from abroad generally has no room for negotiation; plus the pre-sales and after-sales service are not in place, which greatly restricts the development of domestic construction machinery enterprises.
