摘要：Stress analysis is performed on the lifting mechanism of the lightweight bridge crane using the kinetic theory to calculate the bearing reaction of tri-point support of the lifting mechanism and apply it in the loading process of the trolley model,which can shorten the model solution time. The load borne by the low-speed shaft end of the reducer shall be calcu-lated and compared with the simulated result to verify whether the simulation results are correct,develop the trolley rigid-flexible coupling dynamic simulation model,study the dynamic characteristics of the system during the hoisting process, and analyze the load-bearing condition. The paper also puts forward important design links and weak points of the light-weight hoisting mechanism. The study on the mechanical design basis of the lifting mechanism is significant for mastering the design method of the lifting mechanism of the lightweight bridge crane.
