In 80 AD, ancient Greece developed a lifting device that was operated with ropes and pulleys, and the winch and lever were used to wind the lifting on the bobbin. Therefore, the hydraulic lifting platform is now a multifunctional lifting and loading and unloading mechanical device whose lifting system is hydraulically driven, so it is called a hydraulic lifting platform. It can be used for high-altitude operations and maintenance of factories, automatic warehouses, parking lots, municipalities, terminals, buildings, etc.
Hydraulic lifting platforms can be divided into several types. In China, the lifting platform occupies a considerable proportion in mechanical products. According to the statistics of industrial developed countries, the output value of the lifting platform is a combination of compressors, fans and pumps. It accounts for about 5% of the total output value of the machinery industry. At the same time, as an important part of major technical equipment, especially in power, petrochemical, metallurgy, urban water supply and drainage systems, the lifting platform plays a key role, and the amount of action is very large.
In recent years, the world's engineering lift industry has undergone great changes, with the rapid development of off-road tire lifts and all-terrain lift products. Breaking the original product and market structure, under the impact of economic development and fierce market competition, the world engineering elevator market has become more integrated. The world's engineering lift sales have reached $7.5 billion. The main producing countries are the United States, Japan, Germany, France and so on.
Since the 1970s, Japan has become a major producer of engineering lifts. The quality and quantity of its products have increased rapidly. It has already exported to the European and American markets, with the annual total output ranking first in the world. However, at present, the turnover of the annual lifting platform market in China is as high as 50 billion yuan, but the market with more than 10 billion yuan is occupied by foreign lifting platform enterprises. Therefore, the development of China's lifting platform is very important.
