(b) Definitions. Angle of loading is the
inclination of a leg or branch of a sling
measured from the horizontal or
vertical plane as shown in Fig. N–184–5;
provided that an angle of loading of
five degrees or less from the vertical
may be considered a vertical angle of
loading.

whereby the sling is passed under the
load and has both ends, end attachments, eyes or handles on the hook or
a single master link.
Braided wire rope is a wire rope
formed by plaiting component wire
ropes.

joint is a wire rope sling made endless
by joining the ends of a single length of
cable laid rope with one or more metallic fittings.
Cable laid grommet-hand tucked is an
endless wire rope sling made from one
length of rope wrapped six times
around a core formed by hand tucking
the ends of the rope inside the six
wraps.
Cable laid rope is a wire rope composed of six wire ropes wrapped around
a fiber or wire rope core.
Cable laid rope sling-mechanical joint is
a wire rope sling made from a cable
laid rope with eyes fabricated by pressing or swaging one or more metal

HT = Hand Tucked Splice. For hidden tuck splice (IWRC) use Table I values in HT column.
MS = Mechanical Splice.
S = Swaged or Zinc Poured Socket.
1 These values only apply when the D/d ratio for HT slings is 10 or greater, and for MS and S Slings is 20 or greater where:
D=Diameter of curvature around which the body of the sling is bent; d=Diameter of rope.

(vi) Hooks that have been opened
more than 15 percent of the normal
throat opening measured at the narrowest point or twisted more than 10
degrees from the plane of the unbent
hook.
(vii) Corrosion of the rope or end attachments.
(g) Metal mesh slings—(1) Sling marking. Each metal mesh sling shall have
permanently affixed to it a durable
marking that states the rated capacity
for vertical basket hitch and choker
hitch loadings.
(2) Handles. Handles shall have a
rated capacity at least equal to the
metal fabric and exhibit no deformation after proof testing.
(3) Attachments of handles to fabric.
The fabric and handles shall be joined
so that:
(i) The rated capacity of the sling is
not reduced.
(ii) The load is evenly distributed
across the width of the fabric.
(iii) Sharp edges will not damage the
fabric.
(4) Sling coatings. Coatings which diminish the rated capacity of a sling
shall not be applied.
(5) Sling testing. All new and repaired
metal mesh slings, including handles,
shall not be used unless proof tested by
the manufacturer or equivalent entity
at a minimum of 11⁄2 times their rated
capacity.
Elastomer
impregnated
slings shall be proof tested before coating.
(6) Proper use of metal mesh slings.
Metal mesh slings shall not be used to
lift loads in excess of their rated capacities as prescribed in Table N–184–15.
Slings not included in this table shall
be used only in accordance with the
manufacturer’s recommendations.
(7) Safe operating temperatures. Metal
mesh slings which are not impregnated
with elastomers may be used in a temperature range from minus 20 °F to
plus 550 °F without decreasing the
working load limit. Metal mesh slings
impregnated with polyvinyl chloride or
neoprene may be used only in a temperature range from zero degrees to
plus 200 °F. For operations outside
these temperature ranges or for metal
mesh slings impregnated with other
materials, the sling manufacturer’s
recommendations shall be followed.
(8) Repairs. (i) Metal mesh slings
which are repaired shall not be used
unless repaired by a metal mesh sling
manufacturer or an equivalent entity.
(ii) Once repaired, each sling shall be
permanently marked or tagged, or a
written record maintained, to indicate
the date and nature of the repairs and
the person or organization that performed the repairs. Records of repairs
shall be made available for examination.
(9) Removal from service. Metal mesh
slings shall be immediately removed
from service if any of the following
conditions are present:
(i) A broken weld or broken brazed
joint along the sling edge.
(ii) Reduction in wire diameter of 25
per cent due to abrasion or 15 per cent
due to corrosion.
(iii) Lack of flexibility due to distortion of the fabric.

(2) Safe operating temperatures. Natural and synthetic fiber rope slings, except for wet frozen slings, may be used
in a temperature range from minus 20
°F to plus 180 °F without decreasing the
working load limit. For operations outside this temperature range and for wet
frozen slings, the sling manufacturer’s
recommendations shall be followed.
(3) Splicing. Spliced fiber rope slings
shall not be used unless they have been
spliced in accordance with the following minimum requirements and in
accordance with any additional recommendations of the manufacturer:
(i) In manila rope, eye splices shall
consist of at least three full tucks, and
short splices shall consist of at least
six full tucks, three on each side of the
splice center line.
(ii) In synthetic fiber rope, eye
splices shall consist of at least four full
tucks, and short splices shall consist of
at least eight full tucks, four on each
side of the center line.
(iii) Strand end tails shall not be
trimmed flush with the surface of the
rope immediately adjacent to the full
tucks. This applies to all types of fiber
rope and both eye and short splices.
For fiber rope under one inch in diameter, the tail shall project at least six
rope diameters beyond the last full
tuck. For fiber rope one inch in diameter and larger, the tail shall project at
least six inches beyond the last full
tuck. Where a projecting tail interferes
with the use of the sling, the tail shall
be tapered and spliced into the body of
the rope using at least two additional
tucks (which will require a tail length
of approximately six rope diameters
beyond the last full tuck).
(iv) Fiber rope slings shall have a
minimum clear length of rope between
eye splices equal to 10 times the rope
diameter.
(v) Knots shall not be used in lieu of
splices.
(vi) Clamps not designed specifically
for fiber ropes shall not be used for
splicing.
(vii) For all eye splices, the eye shall
be of such size to provide an included
angle of not greater than 60 degrees at
the splice when the eye is placed over
the load or support.
(4) End attachments. Fiber rope slings
shall not be used if end attachments in
§ 1910.184
contact with the rope have sharp edges
or projections.
(5) Removal from service. Natural and
synthetic fiber rope slings shall be immediately removed from service if any
of the following conditions are present:
(i) Abnormal wear.
(ii) Powdered fiber between strands.
(iii) Broken or cut fibers.
(iv) Variations in the size or roundness of strands.
(v) Discoloration or rotting.
(vi) Distortion of hardware in the
sling.
(6) Repairs. Only fiber rope slings
made from new rope shall be used. Use
of repaired or reconditioned fiber rope
slings is prohibited.
(i) Synthetic web slings—(1) Sling identification. Each sling shall be marked or
coded to show the rated capacities for
each type of hitch and type of synthetic web material.
(2) Webbing. Synthetic webbing shall
be of uniform thickness and width and
selvage edges shall not be split from
the webbing’s width.
(3) Fittings. Fittings shall be:
(i) Of a minimum breaking strength
equal to that of the sling; and
(ii) Free of all sharp edges that could
in any way damage the webbing.
(4) Attachment of end fittings to webbing and formation of eyes. Stitching
shall be the only method used to attach end fittings to webbing and to
form eyes. The thread shall be in an
even pattern and contain a sufficient
number of stitches to develop the full
breaking strength of the sling.
(5) Sling use. Synthetic web slings illustrated in Fig. N–184–6 shall not be
used with loads in excess of the rated
capacities specified in Tables N–184–20
through N–184–22. Slings not included
in these tables shall be used only in accordance with the manufacturer’s recommendations.
(6) Environmental conditions. When
synthetic web slings are used, the following precautions shall be taken:
(i) Nylon web slings shall not be used
where fumes, vapors, sprays, mists or
liquids of acids or phenolics are
present.
(ii) Polyester and polypropylene web
slings shall not be used where fumes,
vapors, sprays, mists or liquids of
caustics are present.

(8) Repairs. (i) Synthetic web slings
which are repaired shall not be used
unless repaired by a sling manufacturer or an equivalent entity.
(ii) Each repaired sling shall be proof
tested by the manufacturer or equivalent entity to twice the rated capacity
prior to its return to service. The employer shall retain a certificate of the
proof test and make it available for examination.
(iii) Slings, including webbing and
fittings, which have been repaired in a
temporary manner shall not be used.
(9) Removal from service. Synthetic
