Minneapolis, MN (PRWEB) January 9, 2008
The theatrical industry has had issues with using chain for the last several decades: on one hand, the industry has embraced grade 30 and 43 chains because the link accepts standard hardware used in this industry, but on the other hand, all of the literature for these chains is clearly labeled "Not for Overhead Lifting". Some have tried to solve this issue by using a grade 80 chain, which is labeled for "Overhead Lifting," but standard hardware will not attach to the chain unless it is at an end link. This is not conducive to the easy adjustment often required in a theatrical environment.
SECOA has developed a chain that solves these issues for the theatrical industry. The SECOA Theatrical Chain (STC™) is an alloy chain rated for "Overhead Lifting" for the theatrical industry, but has the link size of a 1/4" grade 30 chain. This means that all of the standard rigging hardware used in this industry with 1/4" chain will be usable with the STC™ chain.
The STC™ chain has many important safety features. It is strong with a 3,250 working load limit based on a 4:1 design factor. Each link is proof tested to twice the working load limit as a part of the manufacturing process. The chain is lot traceable with every tenth link embossed with a coded date stamp. The chain is easily identifiable with every link embossed with "STC" and the chain has a gold iridescent finish. The American- made STC™ chain meets the stringent requirements of OSHA CFR 1910.184 Slings.
SECOA will be offering this revolutionary chain to the theatrical industry at a cost of under $3.00 per foot, which is much less expensive than using turnbuckles and pipe clamps for trimming battens. When compared to grade 30 or 43 chain, adding the STC™ chain to a project will typically add only a few hundred dollars to the overall cost of a project- a small price to pay to meet the requirements of OSHA CFR 1910.184 Slings.
