【Abstract】 This article presents a mathematic model for optimal design of the rigid four bar composite boom weight balancing system of the portal crane. The minimum unbalanced moment and minimum counter weight are considered as the objective function, and the model is solved by the SUMT method. The practical example shows, that the application of optimal design cuts down the power consumption of luffing mechanism thus improving the design.更多还原
