For old houses, shrines, and temples! We utilize traditional construction methods with effective earthquake measures.
In traditional construction methods, the α Damper ExII is useful for earthquake measures that take advantage of the characteristics of wooden frameworks. One of the reinforcement methods for traditional construction is the installation of damping devices. Enhancing the "damping performance," which gradually reduces vibrations, is a way to increase safety without compromising the characteristics of traditional construction. The α Damper ExII, which specializes in damping force performance, can reduce the response deformation during an earthquake without impairing the deformation capacity of traditional construction, allowing for earthquake measures without damaging the framework of traditional construction. [Features] - Can reduce response deformation during an earthquake without compromising the deformation capacity of traditional construction. - Allows for earthquake measures without damaging the framework of traditional construction. *For more details, please download the PDF or feel free to contact us.

Company information
Tokiwa System Co., Ltd. is a company that develops, manufactures, and sells the seismic control device αDamperExII. It is a pioneer in seismic control devices using hydraulic dampers. The αDamperExII has received the number one track record and trust in the Tokai and Tonankai earthquake warning areas, and it will soon be adopted in 10,000 buildings. The αDamperExII is a hydraulic seismic control device that reduces building deformation caused by earthquake shaking by approximately half.
