In the Great East Japan Earthquake 2011, a number of automated warehouse’s functions were suspended for a long time because stacker cranes were prevented from working by loads fallen into the aisles.

After examining the target specifications, the developed control slider is reported. Finally, the results of a shaking table test are presented.
