Anchors and Lifting Eyes

There are two categories of lifting anchor:

  1. Facelift anchor – also named Foot Anchor
  2. Edgelift anchor – including Eye Anchor, Thin Panel Eye Anchor & Edge Lift Anchor

Facelift anchor
Face Anchors are cast into the face of the element with a recess former used to form the hollow into which the Clutch is placed to engage the head of the Anchor.
The foot of the Anchor holds into concrete by developing a pull out cone in the concrete. The diameter of the cone at the face of the concrete is about 6 times the depth of the Anchor.

Edgelift anchor
Edgelift Anchors are cast into the side of the element with a recess former used to form the hollow into which the Clutch is placed to engage the head of the Anchor.
The foot of the Shear Bar stops the lifter pulling out when tilting up the panel. Correct installation of the shear bar is critical for it to work.

Anchor Identification

The NZ Code of Practice states, “All lifting inserts embedded in concrete shall be clearly marked to enable their length and type to be identified after they have been cast into the element.”

Reid™ Eye Anchors use additional reinforcing Hanger Bars to achieve tensile lift capacities in thin sections or low strength concrete.
Please refer to Technical Guide for more details. There is no length stamp on an Eye Anchor because of the need for the Hanger Bar, which can vary in length.

Edgelift Anchors use Hanger Bars to achieve the rated lift capacities in tension.
