[QUOTE="Charlie Zureki, post: 31879, member: 153"] Re: required chain grade for overhead suspension Hello, As someone pointed out...if you have to ask in regards to rigging....you'd best HIRE a rigger. If a chain motor's chain is too short...get longer chain (to it's spec'd length limit, and approved by the chain motor manufacturer), or within easy reach.....add a piece of rigging steel on the down end (easier for the riggers to handle). Use only the type of chain motors designed for the entertainment industry. Use only rated pear-rings, d-rings, shackles (clevises to some), wire rope, and well maintained spansets. Use steel safeties and burlap where necessary. A rigger will know these things above and have proper rigging gear...harness, fall arrest, ropes, shivs (sheaves) etc... Hire a rigger, get proper rigging gear, rig the hangs properly.... and everybody goes home a bit safer. Hammer ps. gotta be a big gauge of chain to get a shackle through [/QUOTE]
