Abstract: To solve the issue of sway during the operation of traditional rubber-tyred container gantry crane(RTG),based on the anti-sway principle of the eight-ropes winding system,the upgrading and renovation methods are proposed to improve the loading and unloading eficiency of traditional RTGs by changing the deflection angle of pulley group on lifting device and the lifting point position. The RTG model is built in the 3D modeling software,and then it is imported into Adams to complete the rope and pulley group modeling,and to set constraints and drives.The traditional RTG pulley group is deflected by , ,and respectively,and the lifting processes of full load,no load,and off load conditions are simulated under the same driving condition. The results show that the deflection pulley group has a certain anti-sway ability,and the pulley group with a deflection of has the best anti-sway effect; compared with the original model,while the pulley group is deflected by ,the swing attenuation of full load is 95.75% ,the swing attenuation of empty load is 78.32% ,and the swing attenuation of unbalanced load is 83.51% ,and the anti-sway effect is significantly improved.
