Development of Seismic Isolation Device for Container Crane

The Great Hanshin Awaji Earthquake

• Almost all of the quays were unavailable.
• All of the 55 container cranes were unavailable.
• Breakdown of cargo handling functions (2 years to recover)
• Decrease in economic activities and international competitiveness

Conventional Seismic Isolation Method

• The conventional method aims to decrease the response acceleration spectrum using seismic isolation rubber etc.

New Seismic Isolation Device (Friction Seismic Isolation Method)

Model Experiment (three-dimensional trembling board)

Institutions available for experimental device set up
