| Abstract: | The paper builds the models at different stages of lifting operation on the basis of analysis of loads influencing crane structure fatigue.It also solves the differential and the transcendental equations of dynamics model with central differential and Newton iteration methods.Calculation of a double-girder overhead traveling crane shows that the method mentioned in this paper is feasible. |
