DYNA Grip ^® Anchorages

Because the DYNA Grip ^® Anchorage is without bond, load monitoring at any time is easy and individual strands in any cable can be replaced when and if necessary.

The Principle:

The DYNA Grip ^® Anchorage without bond consists of an anchor block in which the strands are individually anchored by 3 part-wedges that are designed to provide high dynamic performance. A ring nut is threaded on the anchor block to transmit the cable force via the bearing plate into the structure.

A steel pipe which incorporates centering and sealing provisions for the strands is welded to the anchor block. An elastomeric bearing is installed at a certain distance away from the anchor block to reduce the bending stresses in the strands caused by cable rotation.

Characteristics:

• Fatigue tests with 2 million cycles have proven a stress range of up to 200 N/mm² for the DYNA Grip ^® Anchorage
• Reliable corrosion protection by maintaining the PE sheathing on the strands all the way up to the wedges
• Thanks to a patented procedure, the PE-sheathing does not have to be pre cut exactly to the length of the strands
• Fast and reliable supply according to our principle
