The development status of cranes is discussed from four aspects.

Hoisting machinery refers to mechanical equipment that lifts, lowers or lifts and transports heavy objects through lifting hooks or other spreaders in an intermittent and repetitive manner. In the catalog of special equipment revised by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China in 2014 and approved by the State Council, the definition of hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement, and its scope is specified as rated lifting capacity Lifts greater than or equal to 0.5 t; rated lifting capacity greater than or equal to 3 t (or tower cranes with a rated lifting moment greater than or equal to 40 t m, or loading and unloading bridges with a productivity greater than or equal to 300 t/h), and the lifting height Cranes greater than or equal to 2 m; mechanical parking equipment with floors greater than or equal to 2.

With the country's high-speed infrastructure construction, the domestic hoisting machinery market is expanding rapidly, and the development trend of hoisting machinery is changing to the large-scale of key products, the lightweight of general-purpose products, and the generalization of parts and components.

Facing the good momentum of the development of my country's hoisting machinery industry, we should pay attention to the design and manufacturing technology of hoisting machinery equipment, research and propose countermeasures for the sustainable development of hoisting machinery equipment. In the domestic market, although the hoisting machinery products manufactured in China have entered the forefront of the industry, there are still certain limitations in the awareness of independent innovation and establishing its own brand. The key to promoting the high-quality development of the domestic hoisting machinery industry lies in technological innovation, combined with existing advanced manufacturing technology, and gradually developing towards intelligence.

1. Development history of hoisting machinery The application of hoisting machinery in our country has a long history, and the tangerine used for irrigation in ancient times is the prototype of boom-type lifting equipment. In modern society, with the continuous development of science and technology, hoisting machinery has experienced more than 200 years of development. Its main manufacturing countries are developed countries, such as Germany, Finland, Japan, etc., and its main sales areas are concentrated in North America, Europe and the United States. Asia.

The development of hoisting machinery in our country has also experienced continuous innovation. In recent years, with the continuous improvement of social productivity and the rapid development of transportation, metallurgy, construction and other industries, the demand for lifting machinery and equipment has shown an increasing trend. In some special use environments, higher requirements are put forward for the performance of lifting machinery and equipment.

2. The development status of domestic hoisting machinery my country's hoisting machinery industry has developed under the environment of continuous accumulation and full competition. Since the launch of the first generation of truck cranes in the 1960s, it has gone through a history of more than 50 years, and has made great progress in equipment research and development and manufacturing technology. At present, my country's hoisting machinery is entering the ranks of international competition at an unprecedented speed. The increasing demand for hoisting machinery has promoted the growth of my country's hoisting machinery manufacturing level, and has also improved the technical content of hoisting machinery products. Tonnage polarization and product intelligence are the main trends in the future development of my country's hoisting machinery industry, that is, to large-scale and miniaturized development. Based on the characteristics of products used by users, the demand changes in the lifting machinery industry in recent years are concentrated in: modularization, standardization, combination and practicality of series products; light weight, miniaturization and diversification of general products; product performance automation, Intelligent and integrated; computerized, precise and fast product design; new, beautiful and comprehensive product structure; large-scale, high-speed, durable and specialized key products; fast, professional and fast after-sales service Humanize.

Faced with the diversity of user needs and the impact of fierce competition in the current market, manufacturers of lifting machinery and equipment began to consider accelerating transformation and upgrading, accelerating the integration of industrialization and industrialization, and increasing innovation so that products can keep up with the pace of development of the times.

The "Industry 4.0" concept launched by Germany is the fourth industrial revolution led by intelligent manufacturing, or a revolutionary production method. The strategy aims to transform the manufacturing industry into an intelligent one by making full use of information and communication technologies and cyberspace virtual systems, that is, the combination of information technology and physical systems.

Hoisting equipment is an indispensable part of the manufacturing process of enterprises. In the process of transforming the manufacturing industry to intelligence, the hoisting machinery industry will experience unprecedented challenges, but also opportunities. Facing the intricate market environment, only Keeping up with the pace of the times can promote the high-quality development of my country's hoisting machinery industry.

3. Restricting factors for the development of domestic hoisting machinery Although in the current hoisting machinery industry, my country has become the world's largest hoisting machinery manufacturer and exporter of small-tonnage hoisting machinery products, but in the case of super-large tonnage and intelligent hoisting machinery In the current market competition, the technical competitiveness of domestic enterprises is still insufficient, and the development of new materials and new processes is still an obstacle to the development of the industry. Technological breakthroughs related to super-large tonnage are still more hoped for domestic large-scale enterprises with strong technical strength, while small and medium-sized enterprises may lack technical accumulation and financial support.

Only from the perspective of the growth rate of the output value of the hoisting machinery industry, my country has achieved an increase in output value, export volume and product quality. However, there is still a certain gap between the overall technical strength and developed countries, and there are still two major constraints in policy and market.

 3.1 The tightening of industrial policies In recent years, the country has vigorously advocated energy conservation and environmental protection, and the policies on construction machinery are relatively strict. Under the constraints of my country's existing laws on environmental protection and energy conservation, coupled with the stricter environmental protection policies in some regions, the requirements for design and manufacturing technology in key areas of lifting machinery have increased, and the production cost of lifting machinery has increased significantly, which in turn intensifies market competition. .

 3.2 Market competition is increasingly fierce At present, the domestic manufacturing industry is facing very severe global competition. As an important part of the manufacturing industry, the field of lifting machinery is also deeply impacted by internationalization. For a long time before, some domestic lifting machinery products in my country occupied a very large market share in the domestic market, but later with the continuous addition of some international brands, a fierce competition environment between international and domestic brands has been formed. However, there are still many immature places in the design of domestic cranes, especially in the development of some new products, new materials and new technologies, many foreign products have taken the lead.

4.Conclusion The hoisting machinery industry, as an important support for the economic development of my country's manufacturing industry, will face huge opportunities and challenges. It is necessary for the manufacturing entities to recognize the current development situation, understand their own advantages and differences, introduce, absorb and improve them in time, and strengthen them. Make great efforts in innovation, work hard on the automation, intelligence, digitalization and flexibility of product performance, become the user and beneficiary of the new generation of intelligent production technology, and also become the creator and supplier of advanced industrial production technology.
