5. Flat Panel Riggging ALERT Note: When a rigging is selected where four (4) sling lines are attached to four (4) anchors or to a ring or hook on that line: When four fixed length slings are used, generally at least one sling (or chain) is slightly shorter than the other three. This will cause two anchors to carry the total load and the other two anchors (with the one longer sling) to do no more than keep the slab balanced.

19. NOTE: The information supplied in this presentation represents the minimum recommendations for safe installation of precast products. It is the responsibility of the installer/contractor to evaluate the field conditions in order to prevent sources of additional load (ie. Adhesion of the precast product to mud or ice; jerking of the crane or loader during lifting; bouncing of the precast product AFTER it has been lifted; unbalanced loads prying forces on the cast and lift anchor; etc.). NEVER, under any circumstances, should you allow anyone to stand under or in close proximity to a lifted concrete product. Taglines and push sticks should always be used to guide lifted precast elements. It is the responsibility of the installer/contractor to inspect all lifting hardware and prevent the use of damaged product. Please refer to OSHA part 1910, 1920, and ANSI 10.9 for additional information.
