The container crane of the harbor received the enormous damage in the Hanshin Awaji great earthquake. After that, the container crane with seismic vibration isolation system has been developed and operated in practical use. We proposed the rocking type of vibration isolation system (RVIS) for the container crane instead of the horizontal type of vibration isolation system that is used in bridges and buildings. In this paper, we propose the application of a semiactive control system to the RVIS mechanism to improve the isolation performance. The Kalman filter is used to estimate the system state values. The results of the isolation controlled by the semiactive system are better seismic isolation in performance than the passive RVIS.
