In this paper, three-dimensional model of the flexible steel wire rope was established by using CABLE software in CATIA software. After defining the physical parameters of the steel wire rope, the dynamics analysis model of wire rope was established in motion workbench. Further fully model was assembled and simulated including cranes, tower, ground in motion workbench. Finally, we obtained hoisting structure of the trajectory curve, dynamic response, eccentric structure, flipping, etc., as well as interference with the surrounding objects.
