The steel structure crane beam, as the name implies, is the beam structure used to support the operation of the crane. To meet various production needs in industrial plants, it is generally necessary to add cranes. For this reason, crane beams are considered in the design of steel workshop buildings with cranes.

The Crane girder system is composed of a crane beam (also can be a crane truss), brake structure (brake plate, brake truss), auxiliary truss and bracing (horizontal and vertical bracing), etc. Indeed, when the span of the crane girder and the load of the crane carried are small, the braking structure can also be canceled.
