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 national macro-control policies, the macroeconomic situation has gradually improved, and the downturn in 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 early structural adjustments will Accelerated recovery. Technology leads the future and innovation drives development. So, what are the major technological trends in the construction machinery industry?

    First, 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 on the computer and change parameters, 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, but 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 marketable products.

    Second, personalized and multi-function coexist

    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 rate of the equipment.

    Third, 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 international market competition, and it has become a lot of industries. The "Market Access Permit" 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."

    Fourth, speed up the upgrading

    With the development of modern know-how, 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 the product line has become more and more sophisticated. The major companies in the United States, Europe, and Japan have all launched cameras. The second generation, the third generation until the fifth generation of construction machinery new products.

    Fifth, small and large specifications with the development of

    Large and medium-sized construction machinery is still the mainstream of global construction machinery, with annual sales reaching about US$70 billion, but the trend of construction machinery extending towards miniaturization and enlargement is obvious. The countries of the United States, Europe, and Japan are major consumer markets for construction machinery. The large-scale infrastructure construction projects have been declining. Repair and protection and urban mini-projects have been increasing. In order to save on higher labor costs and improve work efficiency, various 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.

    Sixth, the industrial design concept runs through the product design

    Industrial design is the product's design, also known as 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.
Seventh, robots help the 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 to conduct research on the modern design methodology and applied ergonomics to advocate 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 depends to a large extent on these spare parts, such as transmission components, control components, diesel engines and key hydraulic components, and other high-tech, high-value-added core components. The main parts of the machinery core also depend on imports. This situation has seriously hampered the further development and growth of China's construction machinery companies. 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 a newly 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 technologies such as sensing, advanced control, etc. are controlled by people; small industrial scale, small industrial organization structure, scattered , Weak, lack of backbone enterprises with international competitiveness; weak industrial foundation, high-end and special sensors, intelligent instrumentation, automatic control systems, high-end numerical control systems, robot market share of less than 5%.

    Eight, operating principle through the heart 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 stunned science laid the foundation for the new operating principles of engineering machinery. For example: the application of mechanical vibration, pulse, jet, photoelectric effect and thermal physics has created conditions for the realization of the construction machinery to save resources, improve the quality of the project, increase production efficiency, work reliability, driving comfort and automation.

    Nine, 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 achieved. The overall production efficiency and compaction quality of the roller are improved.

    Ten, telecommunications and intelligent processes

    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 work 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.
