Analysis of the scale of the elevator industry
Elevators refer to equipment used for vertical transportation of personnel, items, or vehicles, which achieves up and down movement through electric drive systems, hydraulic systems, or mechanical transmission systems. It is widely used in the fields of architecture, industry, commerce, and residential areas, providing people with fast, safe, and convenient vertical transportation.
The current development status of the elevator industry shows that the global elevator market is expected to reach around 30 billion US dollars in 2021, and is expected to gradually increase at a stable growth rate in the coming years. The Asia Pacific region (mainly including China, India, and Southeast Asian countries) is the largest region in the global elevator market, occupying a considerable proportion of the global market share. Europe, North America, and the Middle East also hold significant positions in the elevator market.
The current development status of the elevator industry shows that the domestic elevator market reached approximately 250 billion yuan (about 37 billion US dollars) in 2019. The domestic elevator market is showing a steady growth trend. With the acceleration of urbanization, the increase in construction projects, and the growing demand for vertical transportation, the market demand for elevators is also constantly expanding. The domestic elevator market demand is relatively concentrated in first and second tier cities, especially in economically developed areas. However, with the economic development and urbanization process in the central and western regions, the demand for elevators in these areas is gradually increasing.
Elevator industry demand
Demand in the field of architecture: With the continuous increase of high-rise buildings and public facilities, such as office buildings, hotels, hospitals, airports, subways, etc., elevators have become one of the necessary equipment for vertical transportation. In addition, residential communities often use elevators to meet the entry and exit needs of the elderly and disabled, attracting homebuyers.
Industrial demand: The current development status of the elevator industry indicates that in manufacturing, logistics, and other fields, there are many situations that require lifting items or equipment from one height to another, such as car maintenance, warehouse stacking, and production line material lifting. This requires the use of elevators to improve work efficiency.
Requirements in the commercial field: Shopping malls, supermarkets, exhibition halls, office buildings, and other places have a large flow of people. Elevators can provide fast, safe, convenient, and comfortable vertical transportation services to meet people's travel needs.
Special requirements: Due to the increasing demand for the performance and appearance of elevators, some special places have higher requirements for performance and design, such as elevators with unique appearance design, elevators with special requirements for fire resistance, explosion prevention, etc., elevators that meet environmental protection requirements such as low noise and low vibration.
History of the Elevator Industry
Early development (late 19th century to early 20th century): Elevators originated in the late 19th century and were first used in the industrial sector. At that time, the design of elevators was simple, mostly consisting of steam driven hydraulic systems or traditional winches, used to lift heavy objects.
The innovation of electric drive (early to mid-20th century): In the early 20th century, with the development of electric technology, electric elevators began to emerge. Electric powered elevators use electric motors as power sources, which improve the efficiency and safety of elevators and are widely used in construction, industrial, and commercial fields.
Further development of high speed, efficiency, and safety (mid-20th century present): With the continuous advancement of technology, the elevator industry has made significant breakthroughs in control systems, safety devices, and automation. Hydraulic and mechanical transmission elevators have been replaced by more advanced and efficient hydraulic, elevator, and traction driven elevators. Modern elevators have higher load-bearing capacity, faster speed, more precise positioning, and safer equipment protection mechanisms.
Modernization and intelligent development (21st century present): With the rapid development of information technology and intelligent control technology, the elevator industry has entered a more intelligent and automated era. Modern elevators adopt advanced technologies such as digital control systems, sensors, and human-machine interfaces, which can achieve functions such as elevator group control, remote monitoring, and fault warning, providing more convenient, safe, and comfortable lifting services.
Overall, the elevator industry has gone through a development process from simple mechanical equipment to electric drive, high-speed and efficient. The application of modern and intelligent technology has further promoted the development of the elevator industry and met the needs of different fields for safe, efficient and intelligent lifting equipment.
