The construction labor is intensive, and most of the employees in the first-line operations are of low cultural quality. In addition to the complicated working environment, there are many open-air high-altitude operations, especially the high-altitude operations. With the increase in altitude, the difficulty of operations increases and the vertical transportation time increases. The efficiency of the formation of manual operations has decreased, and the industry risks have increased. According to statistical data, the injury accidents in the construction industry have ranked third in the country and jumped to the second place in the industry, second only to mines. In the booming countries in Europe and America, the high-altitude truck industry has experienced long-term development, and both technology and markets have matured. The booming countries and regions of Europe and the United States and other countries started to work on high-altitude vehicles. Since the beginning of the 1920s, it has been developed for nearly a hundred years. High product technology, wide operating range, complete specifications. Rich structure and versatile functions. Overall. Both technology and markets are mature. In Europe and the United States, high-altitude vehicles are a highly prosperous industry with a market size exceeding 50 billion yuan: In the booming countries of Europe and America, the high-altitude truck industry has experienced long-term development, and both technology and markets have matured. Upstream Consumers: The market is mature and highly concentrated. The sales of the top five manufacturers in the world account for more than 70% of the world's top 20 high-altitude machines, and the annual revenue of the top professional high-end car manufacturers such as Terex (Gene) and JLG. Both exceeded 10 billion yuan (all of them are unicorns in the market segment). The European and American markets have been quite mature. The world’s giants have been optimistic about China’s emerging markets and are rushing to plan in China. Middle-stream distribution/leasing companies: The boom in the leasing market is the center of the booming market for high-altitude vehicles. The heightening of the US leasing market is an important guarantee for the advancement of high-altitude vehicles. Compared with the United States, China’s high-altitude trucks have a small lease and a rapid growth rate. Downstream users: The scope of application is extended from time to time by construction, and legislation to safeguard safe consumption accelerates the industry. The use of high-altitude vehicles in China is still relatively narrow, and there are many departments that mainly use electricity, street lamps, traffic, and gardens. Most domestic users are concentrated in stations, subways, shops, factories, power supply, and street lamps. The use of aerial vehicles by other markets is far behind the market itself. In the United States, the progress of aerial vehicles is mainly due to the highly prosperous guarantee of the rental market in the United States. 80% of construction machinery in the United States is in the leasing market, and 10% of construction machinery leasing companies have completed listing. Leasing companies cover a wide range of areas, and effectively promote the progress of the application of aerial vehicles and industry development. At the same time, it also makes the leasing company’s equipment procurement an important source of demand for high-altitude truck manufacturers in the European and American markets.
