Type G Buffer Chain for Bridge Collapse Prevention Structure
A chain type that allows for shock absorption! There are cases where it has prevented loss due to tsunamis in installed bridges.
The "G type" is a bridge anti-fall device that can mitigate shocks even under repeated loading. By using a shockless chain coated with rubber, it can reliably absorb shocks during an earthquake. If there is no deformation after the earthquake load is applied, it can be reused without replacement. The rubber material is a vulcanizate made from a mixture of natural rubber and synthetic rubber. The surface treatment of the steel materials is done with hot-dip galvanizing HDZ 55 (JIS H 8641) to ensure durability. 【Features】 ■ Reliable shock absorption during earthquakes due to the use of a rubber-coated shockless chain ■ Installation position can be changed according to the situation of interfering objects ■ The size of the installation bracket can be reduced ■ Even if the bridge has an angle, it can be accommodated by changing the number of links and the installation angle *For more details, please download the PDF or feel free to contact us.
