During normal operation, it restrains through a trigger to suppress unnecessary vibrations and deformations.
We handle the "Ship Unloader Seismic Isolation Device" developed in collaboration with Kawakami Core Tech Co., Ltd. By conducting vibration tests using a 1/4 scale model of a 600t/h ship unloader, we have demonstrated the effectiveness of its seismic isolation function. Please feel free to contact us if you have any inquiries. 【Features】 ■ During earthquakes of a certain magnitude or greater, the trigger breaks, activating the seismic isolation device. ■ The damping mechanism incorporated in this device reduces damage from lifting due to rocking and to the legs and crane body structure. ■ Composed of mostly maintenance-free parts, daily inspections can be easily performed, such as checking the trigger and rust prevention. *For more details, please download the PDF or feel free to contact us.
