Advanced Elevator Maintenance Network during a Major Seismic Disaster

摘要

The prompt restoring at the time of an earthquake is an important work for elevator maintenance companies in Japan. To meet this mission, we have built up the powerful maintenance network systems which support the restoring work of the damaged elevators. Our maintenance network functioned well against the Great East Japan Earthquake which occurred at 2:46pm on 11th March, 2011. However, new problems appeared at the same time. Especially, avoidance of entrapment in a car resulting from the planned rolling blackout due to the shortage of electric power is important. The current situation and future work of our elevator maintenance network system are presented.
