The 2011 off the pacific coast of Tohoku earthquake and the 2016 Kumamoto earthquake shook many automated storage and retrieval systems and caused palletized goods to fall down from the storage racks. The authors have developed a seismic isolation system in the direction of rack opening for automatic warehouse to prevent goods falling. In this study, shaking table tests were conducted to evaluate a seismic isolation system using inclined rail bearings. As a result, it has been demonstrated that the newly developed seismic isolation system is effective in preventing stored goods from falling down from rack shelves.
