Double Girder Overhead Traveling Crane for Sale

Double girder bridge cranes can be designed in top running or under running style to meet different work needs. Top running overhead traveling cranes can offer more overhead room and greater lifting height than under running crane units. Since the top running cranes travel on the runways to lift materials, they require more on the building’s foundation and support structure. For some facility, more than one overhead cranes are installed and travel on the same runways.

Compared with single beam overhead traveling crane, the double girder crane is more suitable for heavy loads lifting, lowing and moving work, and can be applied to more frequent work occasions. The double beam overhead cranes can be used both indoors and outdoors for material handling, like used in production line, installation and maintenance engineering, shipping port, mining area, steel mills and so on.
