In recent years, among many construction machinery products, excavators have become one of the fastest growing varieties. Industry insiders generally believe that while domestic construction machinery manufacturers have increased investment, they should also take note of the high technical content of the excavator itself, especially the key components and parts with higher technical content. This requires the construction machinery manufacturers to increase While investing in the excavator market, we must pay attention to breaking the bottleneck in technology.
Among the key components of excavators, the development process of key components such as engines, hydraulic systems and components, and transmission components is costly, labor-intensive and time-consuming. The risks involved are large, and sometimes huge amounts of money are invested in them. micro.
Even at present, several famous domestic construction machinery manufacturers such as Sany Heavy Industry, Liugong, and Zoomlion can only choose to use foreign key components to assemble products.
Even after the development of the key components, the original components in the application to the excavator also require a long time to verify the reliability in terms of performance and stability.
For example, Xugong Group, the leading enterprise in the construction machinery industry in China, tried to use the domestically-manufactured parts to assemble excavators in the early years. However, the results were not satisfactory. There were problems such as short engine durability, high oil temperature and water temperature, and poor heat dissipation performance; Excavators made with hydraulic parts are also a lot of problems. They are inconsistent in operation and soft, and have a very negative impact on the whole machine.
At the same time, the technical problems existing in the matching parts of China's excavator industry do not lie in capital and management but in the industrial base. In our country, the industrial base for the manufacture of accessory parts is still very weak, and it is still difficult to change in the short term.
According to related reports, the underdevelopment of China's supporting parts industry has restricted the development of China's excavator industry. For a long time, the country has problems of heavy hosting, light support, and focusing on results and light infrastructure, resulting in an imbalance in the development of the industry. The quality and quantity increase rapidly, and the kits progress slowly.
