Cranes have a wide range of applications in industry. In order to eliminate the swing caused by the operation and improve the loading efficiency, it is necessary to propose a crane anti-swing control method suitable for the industrial environment. At first, we built a dynamic model of crane load swing. Secondly, we proposed a series of crane anti-swing method based on input shaping with pulse input. We superposed different amplitude impulse responses at different moments. The swing angle returned to zero in 1/2,2/3,3/4,??????, （n-1）/n period of system oscillation, when the input was two, three, four,???n impulses . Thus，we can control the angle of the crane load based on POSICAST control theory. Finally, we used MATLAB as the simulation platform and set up the model of anti-swing control of overhead cranes. Numerical and experimental results indicated that the proposed shaper can effectively reduce residual vibrations of cranes.
