1. Overview of lifting machinery
Hoisting machinery is a widely used machinery and equipment, covering many aspects of manufacturing. According to the structure of machinery, lifting machinery can be divided into four categories: light and small lifting equipment, lifts, cranes, and overhead monorail systems. Among them, light and small lifting equipment is more portable and suitable for occasions with low work intensity requirements. A lift is a lifting machine with a vertical stroke, and its lifting route is relatively fixed. Crane refers to a multi-action hoisting machinery that vertically lifts and transports materials horizontally within a certain range. The overhead monorail system refers to the hoisting machinery that the crane trolley runs along the composite line composed of the suspended monorail.
my country's lifting machinery industry started in the 1950s and has experienced more than 60 years of development from its birth to the present. It can be roughly divided into four development stages: the initial period (50s-70s) and the development period (20 1980s-90s), downturn period (late 1990s), rapid development period (21st century to present).
Second, the development status of the crane industry
According to data, the total output value of China's lifting machinery industry has increased from 337.34 billion yuan in 2013 to 422.23 billion yuan in 2017, with a compound annual growth rate of 5.8%. In the context of favorable national policies and good macroeconomic development, all regions of China are accelerating the advancement of infrastructure projects that have been included in the planning priorities, providing for the development of products, equipment, and services related to the lifting machinery industry This creates a larger market space. In the future, the total industrial output value of China's lifting machinery industry will continue to expand and is expected to reach 534.5 billion yuan in 2021. The future development prospects of the lifting machinery industry are broad.
Truck cranes are the most widely used hoisting machinery in my country, accounting for 61% of the market in 2017. Mainly because truck cranes can travel on roads due to their good mobility and wide lifting range, and have the characteristics of rapid transfer. Therefore, truck cranes are mostly adapted to the needs of infrastructure construction such as bridges, railways and ports, and have become the crane market The main application products.
3. Development status of subdivided products in the crane industry
The sales of truck-mounted cranes in China have shown a downward trend since 2013. According to data from the China Engineering Association, the sales volume of truck-mounted cranes in China in 2013 was 63,684 units, and in 2019 it dropped to 15,462 units, a decrease of 75.7%. Mainly because the demand for cranes in the construction industry has become saturated, the sales of truck-mounted cranes will remain at about 15,000 in the future.
Driven by China's stable economic growth and strong construction demand, China's tower crane service market has achieved rapid development in the past few years. The revenue of China's tower crane service market has increased from about 70.2 billion yuan in 2015 to 101.6 billion yuan in 2019, an increase of 44.7%.
Fourth, the future development trend of the crane industry
1. The crane industry is developing towards intelligence
In the context of "Internet +" and intelligent manufacturing, leading companies in the lifting machinery industry use Internet thinking to introduce concepts such as intelligence, informationization, and big data into the design, development, construction, and operation management of the motor unit of lifting machinery. Each link. In addition, lifting machinery companies are actively promoting the construction of the industrial Internet. For example, Zoomlion released the cloud valley industrial Internet platform ZValleyOS based on the equipment application and management of the Internet of Things technology. The platform can assist lifting machinery companies in their digital transformation. Through remote intelligent monitoring of equipment failures, it can realize equipment data collection, platform centralized monitoring and equipment failure early warning functions, and provide industrial equipment for equipment manufacturers, equipment users, maintenance service providers, etc. The demand for multi-level industrial Internet value services such as interconnection platforms and big data analysis.
In the future, as the Internet and big data are gradually applied to the crane industry, the operating costs of the industry will be greatly reduced, and the profits of crane manufacturers are expected to further increase. Therefore, the lifting machinery industry will continue to carry out technological upgrading and innovation, and the intelligentization of the lifting machinery industry will become one of the future development trends.
2. Technical improvement of parts and components of domestic cranes
In order to strengthen China's independent innovation capabilities in the field of lifting machinery parts, relevant companies in the lifting machinery industry should focus on parts technology research and development and product innovation, and enhance local supporting capabilities. In November 2018, a high-end construction machinery and core component industry technological innovation strategic alliance jointly initiated by Xugong Machinery and Zhejiang University with 54 companies and research institutes was established, laying the foundation for the technological development of the construction machinery industry.
In addition, enterprises in the industry have introduced foreign component manufacturers to settle in, integrate industry resources, and enhance the overall strength of the industry through active investment promotion and other methods. At the same time, some hoisting machinery companies are trying to use resource merger or acquisition strategies to extend to upstream parts or deepen the field of midstream equipment to achieve the linkage effect of the industry chain and improve the parts technology of related equipment in the industry. In the future, thanks to China's industrial transformation and greater opening up to the outside world, midstream companies in the lifting machinery industry will further integrate resources, give play to their synergistic advantages, and improve the technology of domestic lifting machinery parts.
3. Modularization of crane products
Hoisting machinery is a series of products in batches. Modular design is used to replace the traditional hoisting machinery design. The components and parts of the hoisting machinery with basically the same function can be made into multifunctional and universal standard modules. By combining different module parts and accessories, different types and specifications of lifting machinery can be formed. Compared with traditional hoisting machinery manufacturing, modularization is of substantial significance to hoisting machinery manufacturing enterprises, which can reduce the cost of each production link of hoisting machinery, improve the degree of generalization, and realize the efficiency and economy of production. In the future, the rapid development of large-scale and intelligent hoisting machinery and the maturity of hoisting equipment technology will accelerate the trend of hoisting machinery manufacturers to modular applications.
