Cable Stay

Amsteele Systems offer both DYWIDAG Systems International and Redaelli Tecna S.p.A. cable stay systems; application dependent.

DYWIDAG’s DYNA Grip Stay Cable System is suitable for heavy road and rail bridges.

The DYNA Grip Stressing Anchorage consists of an anchor block in which the strands are anchored by high fatigue 3 part-wedges. A ring nut is threaded onto the anchor block to transmit the cable force into the structure via the bearing plate. A steel pipe that incorporates bending and sealing provisions for the strands is part of the anchor block. A non-adjustable anchorage with the same provisions for bending and sealing of the strands can be placed at the dead-end side.
