Manufacturer Of Electric Double Girder Overhead Traveling Crane 20ton
Double girder overhead bridge crane can be constructed with either structural steel beams (W flange beams) or welded steel plates, commonly known as box girders. Most bridge cranes up to 35meters span are constructed of structural steel.
The type of bridge girder is determined by considering both the span and capacity of the application. Box girder cranes have a very light weight to span ratio and in many cases can reduce the size of the runway and building structure required to support them as well as reduce the cost of the crane itself. The KIWICRANE engineering team can determine which design is right for your application.
