Underhung overhead crane with complete runways are mainly used for the transportation of materials in indoor machinery manufacturing and processing workshops, assembly workshops, warehouses, material yards, for lifting fixed maintenance equipment such as power plants, and other occasions. They can also be used in metallurgy and casting workshops as auxiliary lifting equipment. Besides, it is not suitable for flammable, explosive, combustible gas, dust and corrosive gas environments. However, it is not suitable for nuclear radiation environment and toxic gas environment.

Underhung cranes are lifting equipment that are placed horizontally over workshops, warehouses and stockyards for lifting materials. Because the two ends of the bridge's underhung cranes are located on tall cement columns or metal supports, and are shaped like a bridge, they are commonly known as "overhung cranes" and "driving cranes." It is a kind of lifting machinery with wide range of use and large quantity.

After understanding the basic parameters of underhung cranes, we must also understand the metal structure frame structure of the bridge crane in detail. Let’s share it with you. The metal structure of underhung cranes is the skeleton of the crane, on which all mechanical and electrical equipment are distributed. It is the load-bearing structure of the crane and makes the crane form a whole mechanical equipment.
