Tests were conducted in direct tension, total of 97 tests, and in a shear direction, total of 8 tests. This paper shows various reinforcement combinations and how they influence the ultimate capacities of plate style edgelift anchor. Based on recent research, the capacity of a lifting insert is influenced by the capability of supplementary reinforcement to distribute stresses when anchor loads are applied. Ultimate capacity information for lifting inserts, and its associated supplementary reinforcement, used in lifting concrete thin walled element are summarised in this paper.
