The electric hoist commonly used in construction has also experienced a buffer period after undergoing a high-speed development. Therefore, it is an important point for crane manufacturers to increase their scientific investment during this buffer period. At present, most enterprises know that the current engineering climbing frame electric hoist market also needs a buffer period to adjust, which not only benefits the sustainable development of the host company, but also creates competition for domestic and foreign accessory parts. A relatively balanced environment. There are three reasons. First of all, the international construction machinery industry is now entering a low-speed development stage. The construction machinery industry is closely related to the economy, and is greatly affected by the macroeconomic operating situation. Moreover, the growth rate of the construction hoist electric hoist is much lower than the average level of the machinery industry, and the characteristics of entering the low-speed development stage are obvious. Secondly, the construction market and manufacturing pattern of electric climbing hoists are relatively stable. The global construction machinery market is mainly concentrated in North America, Western Europe, China and Japan, and these four major markets account for about 70% of the world. At present, a number of emerging construction machinery markets have also begun to rise in recent years. For example, Russia, India and other countries have shown great market potential. Global construction machinery manufacturing is mainly concentrated in the four regions of the United States, Japan, Western Europe and China, with total output accounting for more than 80% of the world. There are also developed countries such as the United States, Japan, Germany and other industrial developed countries. The construction hoist electric hoist is mainly exported, while my country's construction machinery is mainly domestic. European construction machinery exports account for about 55%, Japan is about 70%, the United States is about 50%, and my country is about 18%. To break through this deadlock, manufacturers now have to carry out technological innovation and progress, high-speed work, high-quality assurance, and low prices have become one of the main trends in the development of climbing frame electric hoist. At present, the price of the electric hoist in the market is not expected to fluctuate too much, because the steel price of its production principle has not declined, and the cost from the production of the product to the sale of the enterprise, including raw materials, labor, advertising costs, etc.
