| Abstract: | Aiming at the influence of cargo load on dynamic load of luffing mechanism in the luffing process of four-bar portal crane, a dynamic model of four-bar portal crane’s cargo load is established. By solving and analyzing the model, the dynamic load generated by cargo load on four-bar portal crane in the luffing process is obtained. In this paper, taking a four-bar portal crane in Qinhuangdao as an example, its horizontal dynamic load is calculated, and the results can provide guidance for fatigue analysis and dynamic design of the four-bar portal crane. |
