摘要： A seismic isolation apparatus for loading/unloading a machine is provided to perform a seismic isolation function by using a shear pin as a trigger unit for the seismic isolation. A seismic isolation apparatus for loading/unloading a machine includes a cross linear bearing(54), a rubber laminate(56), and a shear pin(58). The cross linear bearing includes linear bearings(60,62). The linear bearings are crossed in an X-direction and a Y-direction for moving the cross linear bearing in two orthogonal directions. The X-direction is orthogonal to the moving direction of an unloader. The Y-direction is the same with the moving direction of the unloader. The rubber laminate is a structure that a plurality of rubber sheets and a steel plate are laminated between a lower flange and an upper flange. The shear pin sustains the steel structure of a travelling part(30) and a leg part(20) during usual unloading operation. The shear pin is constructed to initiate the seismic isolation when a predetermined amount of weight is applied by the vibration with more than a certain seismic intensity.
