Single Girder Box Type Eot Crane

A single girder crane is used for light duty weight and short period work. It has 20 tons lifting capacity normally and can work maximum for 6 hours. Actually, it is most suitable for 1 to 20 ton lifting capacity. Single girder EOT crane is useful for short time operation and low duty load.Depending on the live load capacity and crane configuration design, a girder is selected to meet or exceed the structural requirements according to CMAA. Box girders (which, as the name implies, are shaped like a box) are used when a crane's capacity or span exceed the acceptable limit for a profile girder.Single Girder Overhead Bridge Cranes. On a single girder crane, the bridge consists of one girder beam supported on each side by an end truck. The trolley and hoist are most commonly underhung—meaning they run on the bottom flange of the bridge. The bridge itself can either be top running or under running in design.
