Dywidag - Strand Anchor System
DYWIDAG Strand Anchor Systems offer increased flexibility and higher capacities compared with traditional bar anchor systems. Higher capacities can be achieved simply by adding additional strands to the tendon bundle. Strand anchors are particularly suited to areas with low headroom or restricted access where flexible bending of the tendon is required. Large multi-strand jacks are available for stressing high-capacity anchors.
