Hydraulic Vibration Control Device for Wooden Houses 'α Damper ExII' *Pamphlet included

Over 10,000 installations. Absorbs shocks and protects wooden houses from earthquakes. Easy to install and maintenance-free.

The "α Damper ExII" is a hydraulic damping device that can be easily installed in wooden houses to suppress the reduction of seismic resistance caused by repeated earthquake shaking. It has been installed in over 10,000 buildings and comes with a 20-year product warranty. We are currently distributing a booklet titled "Building Homes That Resist Earthquakes," which includes the features and test data of the "α Damper ExII"! *Please view it from the download button. 【Overview of the Booklet】 ◎ Features and installation photos of the "α Damper ExII" ◎ Guidelines for the number of units to be installed and examples of installation arrangements ◎ Dynamic loading tests (shear resistance measurement) conducted at the Gifu Prefectural Forest Culture Academy ◎ Performance tests on actual buildings using a "shaker" (measurement of deformation under seismic intensity equivalent to level 7) ◎ High-speed horizontal loading tests (measurement of energy absorption rate) conducted at Shizuoka University ◎ Steady-state vibration tests (measurement of absorbed energy) conducted at Toyota Technological Institute
