The bridge crane is often disturbed by various factors, such as air resistance, wind load impact, system self-damping, track change, and friction during exercise, these uncertainties factors often have an inevitable impact on load swing. Establishing an accuracy model for the crane is the basis for studying the electronic anti-shake control strategy of bridge cranes. The model research started from the four components of the bridge crane, a homework cycle of a crane and the force of the large-catching car operation were analyzed, which included wind load, hoisting quality, and additional resistance caused by rail defects. A bridge crane-load-three-dimensional kinematical model was established and the simulation results were analyzed based on MATLAB. The results show that: the driving force size, the wind load and the load quality can promote the oscillating of the load at different degrees, and when these factors remain unchanged, the swing angle growth decreases.
