Crane's position in the national economy analysis

Material Handling in the entire national economy has a very important position. Improve production efficiency  bridge gantry crane  to ensure safe reliability, reduce material handling cost is important.
According to statistics, in the United States, per 100 yuan of industrial finished products, and material handling costs from $ 20-25 to account for the U.S. factory production process used in material handling work for 80% of total production cycle.
United Kingdom each year for plant and site material handling cost up to one billion pounds' bow when the right foot national wage expenditures ninth.

Thus seen as an important component of material handling equipment steel crane s requirement is very impressive, lifting machinery industry has a broad prospect.
