Bridge-fall prevention system KANSHO-CHAIN

Main Features and Impact Experiments

Main features  

  • ・The use of a shockless chain coated with rubber ensures that the impact during an earthquake is mitigated.
  • ・The mounting position can be changed depending on the situation of interfering items.
  • ・The size of the mounting bracket can be made smaller.
  • ・Even if there is a bevel angle on the bridge, it is possible to respond by changing the number of links and the mounting angle.

ブラケットの取付位置は、干渉物の状況により容易に変更できます。

Shock absorbing confirmation experiment (impact test)

experimental results

Repeat loading performance 

We confirmed the residual performance of the KANSHO-CHAIN under a load equivalent to the permissible load during an earthquake on an actual bridge.
There is no significant change in the load peak or response time and no decrease in shock response performance was observed (KANSHO-CHAIN).
