Hinged-leg type continuous unloaders in which each leg on the sea side is fixed by a pin to the main body are often used for bulk handling in sea ports. For such type of unloaders, we proposed an antiseismic device using linear ball bearing and laminated rubber bearing installed between the traveling gears and the fixed-legs on the land side. Vibration experiments using 1/15 scale model of an actual unloader, and transient response analysis were conducted to evaluate the analysis method and the performance of proposed antiseismic device. From experiments under the El-Centro, Hachinohe and Port Island seismic waves excitation, with using the antiseismic device, the response acceleration was as low as 5 to 12% compared with the case without the device.
