Based on survey analysis for current girder structure of the bridge crane at home and abroad,and analysis for GB/T 3811-2008 Design rules for cranes,in terms of some disadvantages of the girder of domestic bridge cranes such as much heaviness and many consumables,the structure type of the girder is optimized and some major parameters are se-lected like depth-span ratio of the girder,static and stiffness control indexes,etc.,in order to realize lightweight design of the girder of bridge cranes,to push forward the crane to develop in the lightweight and energy-saving direction.
