Analysis of the Position of Cranes in the National Economy

Material handling has a very important position in the entire national economy. It is very important to improve the crane's production efficiency, ensure the safety and reliability of operation, and reduce the material handling costs.

According to statistics, in the United States, material handling costs account for 20 to 25 US dollars per 100 yuan of finished industrial products, and 80% of the total production cycle is used for material handling in a U.S. factory production process.

In the UK, the annual cost of material handling for factories and construction sites amounts to 1 billion pounds, which is one-ninth of the country's national wage expenditure. In 1974, the Committee on Material Handling Costs of the Ministry of Industry of the United Kingdom conducted a survey of 30 companies and pointed out: "The cost of material handling between processes accounts for more than 12% of the processing fee, if we add handling costs within and outside the factory. Estimated to reach 20%-25% of the cost.

The German company Demag also conducted a detailed investigation and confirmed that material handling expenses accounted for 45% of production costs (30% for material handling in the process, and 15% for material handling in the process).

China's Dongfeng Automobile Factory also made statistics. The processing time of auto parts in the factory accounted for only 5%, and the other 95% of working hours were used in handling and storage. To produce 1t products, the materials have to be raised 50t times, and the production of 1t castings has to be carried out 80t times. The production capacity of Dongfeng Automobile Factory is originally set at 100,000, and the material handling equipment accounts for a large part of the total equipment.

It can be seen from this that the demand for cranes as an important component of material handling equipment is considerable, and the crane machinery industry has broad prospects.
