The hoisting machinery is a space transportation device whose main function is to complete the displacement of heavy objects. It can reduce labor intensity and increase labor productivity. Hoisting machinery is an indispensable part of modern production. Some lifting machinery can also carry out some special process operations in the production process to make the production process mechanized and automated.
Hoisting machinery helps humans to realize the lifting and moving of large objects that could not be realized in the past, such as the segmentation of heavy ships, the overall lifting of chemical reaction towers, and the overall lifting of stadium steel roof trusses. Wait.
The use of lifting machinery has huge market demand and good economy. In recent years, the lifting machinery manufacturing industry has developed rapidly, with an average annual growth of about 20%. Because the transportation of materials from the raw materials to the products is often several times or even hundreds of times the weight of the products. According to statistics, for every ton of products produced in the machining industry, 50 tons of materials should be handled and handled during the processing, and 80 tons of materials should be handled during the casting process. In the metallurgical industry, for every ton of steel smelted, 9 tons of raw materials need to be transported. The transfer volume between the workshops is 63 tons, and the internal transfer volume of the workshop is 160 tons. Lifting and transportation costs also account for a high proportion in the traditional industry. For example, the cost of lifting and transporting for machinery manufacturing accounts for 15 to 30% of the total production cost, and the cost of lifting and transportation for metallurgical industry accounts for 35% of total production costs. ~45%, loading and unloading of goods in the transportation industry depends on lifting and transporting machinery. According to statistics, the loading and unloading costs of shipping costs account for 30-60% of the total freight.
