Surely mitigate the impact during an earthquake! A cushioning chain suitable for seismic reinforcement and bridge collapse prevention structures.
The "Buffer Chain (Type G)" is a chain-type bridge anti-fall device that can absorb shocks even under repeated loading. By using a shockless chain coated with rubber, it can reliably mitigate the impact during an earthquake. Even if the bridge has an angle, adjustments can be made by changing the number of links and the installation angle. Applications for skewed bridges can be discussed individually. 【Features】 ■ Reliable shock absorption during earthquakes ■ Installation position can be adjusted according to the situation of interfering objects ■ The size of the installation bracket can be reduced ■ Adjustments can be made by changing the number of links and the installation angle, even for bridges with angles *For more details, please refer to the PDF document or feel free to contact us.
