Are the cables or chains used to suspend loads or platforms required to be designed as lifting equipment? In other words, do you have to use chain or cable that is designated "for lifting" or can you use chain or cable that is "not for lifting" but is used within the chain's or cable's published working load limit? Is there a code or rule for this? For instance, 1/2" Grade 70 transport chain is "not for overhead lifting" but it has a working load limit of 11,300 pounds in the NACM manual. Can it be used to suspend a platform that is walked on and under during construction or maintenance?
