Parameterization and structure optimization is the core of rapidly light-weight design system of complex structure, which is also the key to promote the application of cranes' light-weight technology in company. However, nearly all existing rapid design systems, which are difficult to realize structure's auto-optimization, are focusing on parameterization design. Moreover, most of the published optimization methods use continuous-variables, which make it difficult to find application in industry. In order to develop the rapidly lightweight design system, which including functions like parameterization design, lightweight optimization and so on, the parameterized models, with a loading model that different parts loaded in different environment, of a series cranes have been built, and a twice-optimization method which is composed of zero-order optimization, parameters' rounding and re-optimization is used. Based on the proposed method, a rapid light-weight design system of box-type portal has been realized with software. The application results show that the proposed system significantly shortens the design periods and reduces a lot of designers' work on calculations and design. Also, the total mass of the portal has been reduced 10.5% after optimization, though portals' stain and stress have increased within allowable range.
