Abstract
An edge lift anchor for embedment into a concrete panel, the anchor having a head of generally plate-like form for releasable attachment with lifting equipment, and at least one leg extending from the head, for locking into the surrounding concrete, the head having an eye for receiving a locking bolt of a lifting clutch in the form of a ring clutch, the head having an upper edge engageable by the body of the ring clutch when the clutch body is inclined at the commencement of lifting a cast panel from the horizontal configuration in which it is cast to a generally vertical configuration, wherein the width of the head is such that engagement between the clutch body and the edge of the head at the commencement of lifting from a horizontal configuration is at a sufficient distance from the end of the head that any deformation of the edge of the head caused by engagement with the clutch body under the applied lifting load will be wholly contained within the width of the head.
