摘　　要：在对国内外桥式起重机主梁结构现状调研分析及对GB/T 3811—2008《起重机设计规范》分析的基础上,针对国内桥式起重机主梁偏重、耗材多等缺点,通过优化主梁结构形式及几个主要设计参数的选取,例如主梁高跨比、静刚度控制指标等,达到桥式起重机主梁的轻量化设计,从而推动起重机向轻量化、节能型方向发展。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.
