Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a)
Sling Use. Wire rope slings shall not be used with loads in excess of the rated
capacities shown in Tables S-3 through S-14. Slings not included in these
Orders shall be used only in accordance with the manufacturer's
recommendations.
(b) Minimum Sling
Lengths.
(1) Cable laid and 6 x 19 and 6 x 37
slings shall have a minimum clear length of wire rope 10 times the component
rope diameter between splices, sleeves or end fittings.
(2) Braided slings shall have a minimum clear
length of wire rope 40 times the component rope diameter between the loops or
end fittings.
(3) Cable laid
grommets, strand laid grommets and endless slings shall have a minimum
circumferential length of 96 times their body diameter.
(c) Safe Operating Temperatures. Fiber core
wire rope slings of all grades shall be permanently removed from service if
they are exposed to temperatures in excess of 200° F. When nonfiber core
wire rope slings of any grade are used at temperatures above 400° F, or
below minus 60° F, the sling manufacturer's recommendations shall be
followed.
(d) End Attachments.
(1) Welding of end attachments, except covers
to thimbles, shall be performed prior to the assembly of the sling.
(2) A prototype of each welded end attachment
shall be proof tested by the manufacturer or equivalent entity to check the
design and welding method at twice the rated capacity before production is
started. Subsequent tests of random samples shall be made. The manufacturer or
equivalent entity shall provide a certificate of such tests which the employer
shall retain and make available for examination by the Division upon
request.
(3) Where rope clip
attachments are used, they shall be made with U-bolts on the dead or short end
of the rope and the saddle on the live end. The minimum number of clips for end
attachments shall be not less than indicated in manufacturer's tables, but in
no case shall be less than three for any permanent installation. Clips shall be
drop-forged steel. The clips shall be spaced at a distance equal to at least
six times the diameter of the rope. All clip or clamp bolts shall be kept tight
after tightening while rope is under tension.
(e) Removal from Service.
Wire rope slings shall be immediately removed from
service if any of the following conditions are present:
(1) Six randomly distributed broken wires in
one rope lay, or 3 broken wires in one strand in one rope lay.
(2) Wear or scraping of one-third the
original diameter of outside individual wires.
(3) Kinking, crushing, bird caging or any
other damage resulting in distortion of the wire rope structure.
(4) Evidence of heat damage.
(5) End attachments that are cracked,
deformed or worn to the point where the rated capacity is reduced.
(6) 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.
(7) Corrosion that is of such severity or
extent as to reduce the rated load capacity of the rope or end
attachment.
(8) One or more broken
wires within one rope lay of the end attachments.
(f) Knots. Eyes in wire rope slings shall not
be formed by using knots.
(g)
Employers must ensure that wire rope and wire-rope slings:
(1) Have permanently affixed and legible
identification markings as prescribed by the manufacturer, and that indicate
the recommended safe working load for the type(s) of hitch(es) used, the angle
upon which it is based, and the number of legs if more than one; and
(2) Not be used without affixed and legible
identification markings as required by subsection (g)(1) of this
section.
