ASME B30.9 pdf download Slings Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings
fabric (metal mesh): the flexible portion of the sling exclusive of end fittings consisting of a series of transverstspirals and cross rods.
fabric length (mefal mesh): the distance of metal meshbetween the end fittings.
fabric thickness (mefal mesh): the nominal overall thicknessof the spirals.
fabrication efficienci: the sling assembly strength, as apercentage of the material strength prior to fabrication.fitting: hardware on the end of a sling
grontmiet sling: a variety of an endless slinghitch, basket: a method of rigging a sling in which thesling is passed around the load and both loop eyes orend fittings are attached to the lifting device.
hitch, choker: a method of rigging a sling in which thesling is passed around the load, then through one loopeye, end fitting, or other device, with the other loop eyeor end fitting attached to the lifting device. This hitchcan be done with a sliding choker hook or similar device.hitch (hitched): a method of rigging (attaching) a slingtemporarily to a load or object for the purpose of liftinghitch, verfical: a method of rigging a sling in which theload is attached to the loop eye or end fitting at oneend of the sling and the loop eye or end fitting at theother end is attached to the lifting device. Any hitchless than 5 deg from the vertical may be considered avertical hitch.
horizonfal angle: the acute angle between the horizontalplane and the leg of the rigging, also known as the angleof loading.
length, sling; the distance between the extreme bearingpoints of the sling.
multiple-leg wire rope slings: same as sling length aboveexcept the gathering ring, master link, or similar fittingis not included in the length dimension.
single-leg slings with end fittings: measured from pullto pull of end fittings or eyes.
single-leg slings wwithout end fittings: measured from pullto pull or from bearing to bearing of eyes
link, masfer: forged or welded steel link used to supportall members (legs) of an alloy steel chain or wire ropesling
link, master coupling: alloy steel welded coupling linkused as an intermediate link to join alloy steel chain tomaster links.
link, mechanical coupling (alloy steel chain): a nonwelded.mechanically closed link used primarily to attach fittingsto allov steel chain.
loop eve (web sling): a length of webbing that has beenfolded back upon itself, forming an opening, and joinedto the sling body to form a bearing surface.
