The demand for hydraulic control systems in the construction machinery industry will not decrease in the short term, and will still maintain an important position in specific areas in the future, but the demand structure may undergo some changes, which are reflected in the following aspects:

1.In the short term, demand is stable and necessary:

Performance advantages meet the needs of the industry: the hydraulic control system has the advantages of high power density, stepless speed regulation, fast response speed, and can withstand large loads, etc. These characteristics are highly compatible with the operation needs of construction machinery. For example, in large construction machinery such as excavators and cranes, powerful power and accurate control are needed to complete complex tasks, and the hydraulic control system can well meet these requirements. In the short term, it is difficult for other technologies to completely replace its advantages in these aspects.

Maintenance and upgrading of the stock market: there are a large number of construction machinery equipped with hydraulic control systems on the market, which need to be maintained, repaired and upgraded during use, which will continue to generate demand for hydraulic control system related parts and technical services.

2.Medium and long term demand structure changes:

Continued demand for high-end, large-scale equipment: With the continuous advancement of large-scale infrastructure construction, energy development and other projects, the demand for large-scale, high-end construction machinery will continue to grow. This type of equipment often has higher requirements for power and handling performance, and the application of hydraulic control systems in these large and high-end equipment is still irreplaceable. For example, large shield machine, super large crane, etc., hydraulic control system is its core power and control system.

3.Integration and development of new technologies: 

The hydraulic control system will continue to integrate with electronic technology and intelligent control technology to form a more intelligent and efficient hydraulic control solution. For example, through the use of electro-hydraulic proportional control, digital hydraulic technology, etc., improve the control accuracy and response speed of the hydraulic system to meet the growing intelligent operation needs of construction machinery.

Some areas may face certain challenges:

The impact of the development of new energy equipment: In the context of increasing environmental protection requirements, electrification, hybrid and other new energy construction machinery has developed rapidly. In some small or environmentally demanding construction machinery fields, electric drive systems may gradually dominate, thereby reducing the need for hydraulic control systems to a certain extent. However, in the construction machinery of medium and large scale and heavy duty operation, the hydraulic system still has advantages.

Alternative possibilities brought by technological upgrading: With the continuous progress of science and technology, some new transmission and control technologies, such as magnetorheological technology, new pneumatic technology, etc., may continue to develop and mature, and may form a certain competition for hydraulic control systems in some specific application scenarios, but it will take a long time and technological breakthroughs to completely replace hydraulic control systems.
