With the increasing demand for large-tonnage cranes in nuclear power and other industries, the research for cranes superlift is increasingly urgent. Taking 3500t crawler crane for instance, a new kind of hydraulic drive linkage system superlift mechanism is designed and a new design method for size parameters of linkage superlift mechanism based on genetic algorithm is proposed in this paper. Take minimum length of the luffing rod for the optimization target when superlift counterweight achieves the limitation position, according to the theory of linkage mechanism and crane structure and performance requirements, the constraints of linkage mechanism is established. By using design method which has been proposed to acquire length of luffing rods, MATLAB is applied to stimulate motion gesture of linkage superlift mechanism. The results show that size parameters of the luffing rods are reasonable, there is no dead spots in motion, and it can meet all design requirements. This paper provides a theoretical foundation and a new design approach for superlift mechanism of crane.
