Volume B30.9 includes provisions that apply to thefabrication, attachment, use, inspection, and mainte-nance of slings used for lifting purposes, used in con-junction with equipment described in other volumes ofthe B30 Standard,except as restricted in B30.12 and
B30.23.Slings fabricated from alloy steel chain,wirerope, metal mesh, synthetic fiber rope, synthetic web-
bing , and synthetic fiber yarns in a protective cover(s)are addressed. Slings fabricated from other materials orconstructions other than those detailed in this Volumeshall be used only in accordance with the recommenda-tions of the sling manufacturer or a qualified person.
abnormal operating conditions: environmental conditionsthat are unfavorable, harmful, or detrimental to or forthe operation of a sling, such as excessively high or lowambient temperatures;exposure to weather; corrosivefumes; dust-laden or moisture-laden atmospheres; andhazardous locations.
abrasion: the mechanical wearing of a surface resultingfrom frictional contact with other materials or objects.angle of choke: angle formed in a sling body as it passesthrough the choking eye or fittings.
angle of loading: the acute angle between horizontal andthe leg of the rigging, often referred to as horizontalangle.
assenbly: a synonym for sling.See sling.
authorized: approved by a duly constituted administra-tive or regulatory authority.
body (sling): that part of a sling between the eyes, endfittings, or loop eyes.
braided woire rope: a rope formed by plaiting componentwire ropes.
braided wwire rope sling: a sling made from braided rope.bridle sling: a sling composed of multiple legs with thetop ends gathered in a fitting that goes over the lift-ing hook.
cable-laid rope: a cable composed of six wire ropes laidas strands around a wire rope core.
cable-laid rope sling,mechanical joint: a wire rope slingmade from a cable-laid wire rope with eyes fabricatedby swaging one of more metal sleeves over the ropejunction.
component: see fitting.
cross rod: a wire used to join spirals of metal mesh toform the complete fabric.
D/d ratio: the ratio between the curvature taken by thesling, D, and the diameter of the component rope, d.design factor: ratio between nominal or minimum break-ing strength and rated load of the sling.
designated person: selected or assigned by the employeror employer’s representative as being competent to per-form specific duties.
end fitting: terminal hardware on the end of a sling.See sling.
endless and grommet coire rope slings
cable-laid endless sling , mechanical joint: a wire rope slingmade endless from one continuous length of cable laidrope with the ends joined by one or more metallicfittings.
cable-laid grommet,hand-tucked: an endless wire ropesling made from one continuous length of rope formedto make a body composed of six ropes around a ropecore.The rope ends are tucked into the body, thus form-ing the core. No sleeves are used.
strand-laid endless sling , mechanical joint: a wire ropesling from one continuous length of wire rope with theends joined by one or more metallic fittings.
strand-laid grommet , hand-tucked: an endless wire ropesling made from one continuous length of strand formedto make a six-strand rope with a strand core. The strandends are hand tucked into the body. No sleeves are used.eye opening: the opening in the end of a sling for theattachment of the hook, shackle, or other lifting deviceor the load itself.
