The anchor selection, together with additional reinforcement, and rigging arrangements is influenced by: - The dead weight of the element - The number of anchors in the element and the configuration of the anchor - Capacity of the anchor at the specific concrete compressive strengths at time of lift - The dynamic loads applied during lifting ...

In this case, concrete base material might be undamaged. Pull-out: the anchor is pulled out from the drilled hole partially damaging the surrounding concrete. When the concrete is damaged the failure is also indicated as pull-through. Concrete cone: after reaching the load-bearing capacity a cone shape is formed.
