[QUOTE="Matthew Haber, post: 31874, member: 190"] Re: required chain grade for overhead suspension But this is concert production not industry... Tim, as you know, grade 70 is not rated for overhead lifting. If something were to happen you would be in deep shit as would anyone who told you over an internet forum that it is okay to misuse it. Rules in rigging are not meant to be broken, they are meant to be followed to the letter. You can use properly rated and terminated aircraft cable for suspending the motors. That will be a boatload cheaper than grade 80 chain and it will actually be a safe/approved use if done properly. That said, if you have to ask, you should be consulting a qualified local rigger.
