摘要： A lifting system for a concrete component comprises a void former incorporated into the component during casting and which provides within the component a void which receives a locking pin of a lifting anchor assembly which is locked within the void by rotation of a locking pin. The lifting anchor assembly has a visual indicator to indicate when the pin is in its locked condition within the void, and a pivotal lifting shackle of the assembly is prevented from movement into a position in which lifting can take place until the pin is in its locked condition. Preferably a base of the void former is configured to retain components of a jacking system by which a concrete slab used for road repair can be jacked into a level configuration with the remainder of the roadway when it has been positioned by use of the lifting system.

摘要： 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.
