China Construction Machinery Industry Development Trend

Construction machinery gradually began to pick up in 2016, but uncertainties affecting the economic operation of the industry still exist. Experts predict that the machinery industry will still be severely tested. With the gradual implementation of the country's macroeconomic control policies, the macroeconomic situation has gradually improved, and the downward trend of the machinery industry will gradually stabilize. In addition, positive factors for the development of the industry will continue to accumulate, and some enterprises, industries, and regions with earlier structural adjustments will Accelerate recovery; technology leads the future, innovation drives development; the future of construction machinery industry will present the following mainstream technology trends:

Modular design and virtual manufacturing

Modular design includes what was previously referred to as generalization of componentization and software modularization in the design process. Modularity of the design software enables various different systems or components to be assembled and changed parameters on the computer, thereby greatly speeding up the design and development of new products. Information technology and the globalization of the global economy have created conditions for the virtual manufacturing of machine manufacturing. Among the major multinational companies in construction machinery, a clear trend is for manufacturers to concentrate their efforts on development research and equipment assembly, and no longer manufacture parts, and instead push it to parts suppliers. Product host manufacturers and component suppliers and scientific research and development organizations collaborate with each other to bring into play the spirit of the initiative of all parties and jointly develop and produce products that are marketable.

Personalization and multi-function coexistence

The development of engineering categories, materials, and scale, and the differences in construction environments have brought about a demand for personalized and versatile construction machinery, while the development of modern design technologies and flexible manufacturing technologies has created conditions for product individuation and multi-functional realization. . Personalized products appear to adapt to a specific working condition. The use of multiple machines is another direction for the development of construction machinery. This will undoubtedly increase the utilization of equipment.

Environmental protection requirements are increasing

For the sustainable development of human society and economy, the world’s public has made increasingly stringent demands on environmental protection. Whether or not construction machinery has good environmental performance will become one of the important indicators for participating in the competition in the international market, and now it has become many industries. The "market access permits" of developed countries. Therefore, all countries in the United States, Europe, and Japan have actually developed engineering machinery that is "friendly to people and the environment."

Faster upgrading

With the development of modern core technologies, the technological development and innovation of the world's engineering machinery products have been more rapid, the cycle of replacement has become shorter and shorter, product groups have been broadened, and product lines have become more and more sophisticated. Major companies in the United States, Europe, and Japan have successively introduced products. The second generation, the third generation until the fifth generation of construction machinery new products.

Small and large scale development

Large and medium-sized construction machinery is still the mainstream of construction machinery in the world, with annual sales of about 70 billion US dollars. However, the trend toward miniaturization and large-scale expansion of construction machinery is obvious. The countries of the United States, Europe, and Japan are major consumer markets for construction machinery. The large-scale infrastructure construction projects are declining. Repair and protection and urban minor projects are increasing. In order to save on manpower cost and improve work efficiency, various types of small, Microengineering machinery has come out one after another. These mechanical equipment can be used for construction work in narrow areas or in residential homes and small projects.

Industrial design concept runs through product design

Industrial design is the product's design, also called the product's artistic form. The shape design of the construction machinery can make the shape of the machine unify with its structure, function and use requirements, and it is in harmony with human physiological and psychological. This design should include appropriate proportions of various departments, smooth body, color coordination, beautiful layout of the instrument, as well as easy intuitive operation and a striking trademark symbol. At present, major companies in the world have attached great importance to the industrial design of products and have appeared specialized research and design institutions.

Robot assists construction machinery manufacturing

The principle of ergonomics has received attention Since the 1980s, many of the world's largest construction machinery manufacturing companies have invested a lot of manpower and capital in researching modern design methodologies and applying ergonomics to promote people-oriented design concepts, focusing on machines. Coordination with people. The application of electronic technology to construction machinery has greatly simplified the driver's operating procedures and improved the technical performance of the machine. The use of electronic control can automatically select the operating mode of the machine; the use of electronic monitoring can promptly find and eliminate the failure of the machine system; the use of electronic sensors processed by the microcomputer can automatically detect the machine's job quality.

In the transition process of emerging industries and traditional industries, robots all play a "catalyst" role. In the construction machinery industry, robots often perform spot welding, arc welding, painting, and assembly on the production line, which can not only ensure the stability of product quality, improve labor productivity, but also improve workers' working conditions and labor intensity. In recent years, China's construction machinery industry has ushered in rapid development and it is urgently needed to upgrade and transform. In order to compete for greater market share in the fierce competition and get rid of the homogenization of products, we must strengthen the automation level of the production line and vigorously introduce robots. Or missing.

In addition, the performance and price of construction machinery products largely depend on these parts, such as transmission components, control components, diesel engines and key hydraulic components, and other high-tech, high-value-added core components. The main supporting parts of the mechanical core also depend on imports. This situation has seriously hampered the further development and growth of China's construction machinery enterprises. Because the foreign companies that control the core spare parts usually adopt the method of starvation, only a certain amount of accessories products are produced each year, so as to achieve the purpose of guaranteeing price control. As an emerging industry that is nurturing and growing, China's smart manufacturing equipment industry still has outstanding problems, mainly manifested in: weak technological innovation capabilities, new sensing, advanced control and other core technologies are restricted by people; industry is small, industrial organization structure is small, scattered , Weak, lack of backbone enterprises with international competitiveness; weak industrial base, high-end and special sensors, intelligent instrumentation, automatic control systems, high-end numerical control systems, robots market share of less than 5%.

Working principle through and breakthrough

Principles of innovation and breakthrough in operation, construction machinery operating principles include cutting, crushing, backfilling of earth and stone, screening, mixing and heating of geotechnical materials, paving, leveling, and compaction of the mixture. The theory of these operations was originally based on bionics and Newtonian mechanics, and the development of modern science laid the foundation for the new operating principles of engineering machinery. For example, the application of mechanical vibration, pulse, jet, photoelectric effect, and thermophysics has created the conditions for the construction machinery to save resources, improve project quality, increase production efficiency, work reliability, driving comfort and automation.

Hydraulic transmission

In the 1960s, it began to be applied to road rollers. It has been popularized and popularized only for more than a decade. The existing road rollers' walking, vibration, steering brake and other systems have realized full hydraulic transmission. The hydraulic transmission greatly simplifies the design of the roller driving and operating system. The smooth operation of the hydraulic transmission is convenient and labor-saving, and the stepless speed regulation and automatic control are easily realized, which generally improves the production efficiency and compaction quality of the roller.

Telecom Integration and Intelligent Process

Modern engineering machinery should be humanized and spiritual. Spiritual engineering machinery is an integrated telematics system with mind-mind (micro-computer) sensory organs (sensors), neural networks (electronic transmissions), internal organs (power), and hand-foot bones (working mechanism and walking device). The combination of electronic technology and sensors and mechanical devices has enabled the automatic monitoring and automatic control of construction machinery. The electronic sensor is the sensory organ of the machine and telecommunication. It is the medium between the machine and its operating object. The electronic technology based on the microcomputer is the brain and central nervous system of the telecommunications. It accepts various information sent by the sensor and performs calculations. After processing, instructions are issued on the execution part of the machine.
