Chains

Alloy steel chain slings shall have permanently affixed durable identification stating size, manufacture's gauge, rated load and angle upon which the rating is based, reach, number of legs, and sling manufacturer.  Rated loads for alloy steel chain sling shall conform to ASME SP.B30.9 Standards on Alloy Steel Chain Slings, Section ASME B30.9c-2000.  Hooks, rings, oblong links, pear-shaped links, welded or mechanical coupling links or other attachments shall have a rated load at least equal to that of alloy steel chain with which they are used.  In those special cases where particular usage makes this impractical, the sling shall be marked with a rated load consistent with the least working load rating of any component.
