This deviator slides along with the cable in the axial direction to prevent the scratches of the cable by friction caused while post-tensioning work, etc.

Anchorage of the external cable

Stress the cable and fix it with nuts by using outer screw of the sockets that are attached to the cable at the both ends. Material of sockets and nuts is stainless steel.
In this bridge, load cells are attached to each cable for monitoring changes in tension.
