R11SP Erection head anchor with shear plate
The R11SP Erection Head Anchor with Plate is designed and used in the same way as the R11 Erection Head Anchor, but it adds an additional shear plate to give more shear capabilities and avoid the need for a shear bar. It is intended to avoid concrete spalling during the lifting process by controlling the rotation of the ring clutch.
