BASE ISOLATION APPARATUS, LIFTING APPARATUS, AND BASE ISOLATION UNIT
A structure having limited supportable portions has been difficult to isolate from vibration in the direction in which a load is applied. A base isolation apparatus includes a Z-axis base isolation unit, an X-axis base isolation unit, and a Y-axis base isolation unit. The base isolation unit includes a vibration-source connector, an isolated-object connector, a lock device disposed between the isolated-object connector and the vibration-source connector for switching between a state of fixing the isolated-object connector and a state of making it movable, a distance recovery device for generating a force to cause an amount of change in distance to approach zero, depending on the amount of change, and a vibration damper for generating a force in an orientation of hindering the change, depending on the rate of change in distance.
