Patent number: 11015335Abstract: 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.Type: GrantFiled: August 24, 2020Date of Patent: May 25, 2021Assignee: Illinois Tool Works Inc.Inventors: Robert Urquhart Connell, Andrew Saul Barraclough, Alexander Charles Knott
