It is of utmost importance that anyone using this publication read and understand all warnings and other information listed below and/or adjacent to the product description. All products are sold with the express understanding that the purchaser is thoroughly familiar with the correct application and safe use. Use all products properly, in a safe manner and for the application for which they were intended. CHARLESTON’S/CAROLINA’S RIGGING assumes no responsibility for the use or misapplication of any product sold by this firm. Responsibility for design and use decisions rests with the user.

IMPORTANT WARNINGSREMEMBER: ANY PRODUCT WILL BREAK IF ABUSED, MISUSED OR OVERUSED. Any well-designed and well-built product can become hazardous in the hands of a careless user. THEREFORE:

It would be impossible in the scope of this publication to list all possible dangers and misapplications associated with the use of all products contained herein. However, in order to promote safe rigging habits, the most common hazards associated with the use of these products are outlined.

Rigging manuals or other, more specific, literature should be consulted for more detailed information and cautions.

exceed the Work Load Limit (WLL) or Rated Capacity. The Work Load Limit is the maximum load which should ever be applied to the product, even when the product is new and when the load is uniformly applied - straight line pull only. All catalog ratings are based upon usual environmental conditions, and consideration must be given to unusual conditions such as extreme high or low temperatures, chemical solutions or vapors, prolonged immersion in salt water, etc. Such conditions or high-risk applications may necessitate reducing the Work Load Limit..

- Components must match. Make certain that components such as hooks, links or shackles, etc. used with wire rope (or chain or cordage) are of suitable material and strength to provide adequate safety protection. Attachments must be properly installed and must have a Work Load Limit at least equal to the product with which they are used.REMEMBER: Any chain is only as strong as its weakest link.- Keep out from under a raised load. Take notice of the recommendation from the National Safety Council Accident Prevention Manual concerning all lifting operations:

“All employees working with cranes or hoists or assisting in hooking or arranging a load should be instructed to . From a safety standpoint, one factor is paramount: Conduct all lifting operations in such a manner that, if there were an equipment failure, no personnel would be injured. This means

- Avoid impact jerking or swinging of load - Work Load Limit will not apply. A shock load is generally significantly greater than the static load. - Inspect products regularly for visible damage, cracks, wear elongations, rust, etc. Protect all products from corrosion. The need for periodic inspections cannot be overemphasized. No product can keep operating at its rated capacity indefinitely. Periodic inspections help determine when to replace a product and reduce rigging hazards. Keep inspection records to help pinpoint problems and to ensure periodic inspection intervals.

Due to the diversity of the products involved and uses to which they can be put, it would be counterproductive to make blanket recommendations for inspection procedures and frequency. Best results will be achieved when qualified personnel base their decisions on information from rigging and engineering manuals and on from actual use in the field.

Frequency of inspection will depend on environmental conditions, application, storage or product prior to use, frequency of use, whether or not life, limb or valuable property are at

risk, etc. When in doubt, inspect products prior to each use. Carefully check each item to be inspected for wear, deformation, cracks or elongation - a sure sign of imminent failure. Immediately withdraw such items from service.

Rust damage is another potential hazard. When in doubt about the extent of corrosion or other damage, withdraw the items from service.

Destroy, rather than discard, items that have been judged defective. They might be used again by someone not aware of the hazard of the defect.

DEFINITIONS

WORK LOAD LIMIT (WLL) - The Work Load Limit is the maximum load which should never be applied to the product, even when the product is new and when the load is uniformly applied - straight line pull only.Avoid side loading. Never exceed the Working Load Limit.

PROOF TEST LOAD (PROOF LOAD) - The term “Proof Test” designates a quality control test applied to the product for the sole purpose of detecting defects in material or manufacture. The Proof Test Load (usually twice the Work Load Limit ) is the load which the product withstood without deformation when new and under laboratory test conditions. A constantly increasing force is applied in direct line to the product at a uniform rate of speed on a standard pull testing machine.

BREAKING STRENGTH/ULTIMATE STRENGTH - Do not use breaking strengths as criterion for service or design purpose. Refer to the Work Load Limit instead.

Breaking strength is the average force at which the product, in the condition it would leave the factory, has been found by representative testing to break when a constantly increasing force is applied in direct line to the product at a uniform rate of speed on a standard pull testing machine.

REMEMBER: Breaking strengths, when published, were obtained under controlled laboratory conditions that are almost always impossible to duplicate in actual use.

DESIGN FACTOR - (sometimes referred to as safety factor) - An industry term denoting theoretical reserve capability. Usually computed by dividing the catalog Breaking Strength by the catalog Work Load Limit and generally expressed as a ratio. For example: 5 to 1.

SHOCK LOAD - A load resulting from the rapid change of movement, such as impacting, jerking or swinging of a static load. Sudden release of tension is another form of shock loading. Shock loads are generally significantly greater than static loads. Any shock loading must be considered when selecting the item for use in a system. AVOID SHOCK LOADS.

IMPORTANT: READ WARNINGS BEFORE USING THIS PUBLICATION

EFFECTS OF ANGLES ON SLING CAPACITIES

WIRE ROPE SLING REJECTION CRITERIA

1. For strand laid and single part slings, ten (10) randomly distributed broken wires in one rope lay, or five (5) broken wires in one strand in one rope lay.

2. For cable laid and braided slings of less than 8 parts, twenty (20) randomly distributed broken wires in one lay or braid, or on (1) broken strand per sling.

3. For braided slings of 8 parts or more, forty (40) randomly distributed broken wires in one braid, or two (2) broken strands per sling.

4. Severe localized abrasion or scraping.5. Kinking, crushing, birdcaging or any other damage

resulting in distortion of the wire rope structure.

6. Evidence of heat damage or if a wire rope sling having a fiber core is exposed to temperatures in excess of 200° F. or if a wire rope sling having a steel core is used at temperatures above 400° F or below minus 60° F.

7. End attachments that are cracked, deformed, or worn.

8. Deformation–any visibly apparent bend or twist from the plane of the unbent hook. Throat opening–any distortion causing an increase in throat opening of 5% not to exceed 1/4in. (6mm) (or as recommended by the manufacturer)

9. Corrosion of the rope or end attachments.10. Unlaying or opening up of a tucked splice.

Conditions such as the following should be sufficient reason for consideration of sling replacement:

The rated capacity of a multiple leg sling is directly affected by the angle of the sling leg with the vertical. As this angle increases, the stress on each leg increases with the same load. If the sling angle is known, the capacity can be readily determined by multiplying the sling’s vertical capacity by the appropriate load angle factor from the table at right.

Example:A multiple leg sling with a rated capacity of 2000lb. will have a reduced capacity of 1000lb. (2000 x .500) when sling legs are at an angle of 60° with vertical.

how to inspect web slings.All of our synthetic web products are designed for long life under punishing conditions, but they will eventually wear out after extended use. The key is knowing when to replace them, and that’s why it’s very important to inspect your slings on a regular basis.

We’ve developed an inspection program based on the procedure outlined in ANSI B30.9 that will make the most of your investment. It’s based on four sound beliefs:

• The importance of following regular and uniform inspections.• A respect for the capabilities and limitations of synthetic web

slings.• The need to keep complete, permanent records.• Perhaps most importantly, a lot of common sense.

how often to inspect slingsThe frequency of inspection depends on three important factors:

1. Slingusage–themoreyouuseasling,themoreyouneedtoinspectit.

2. Theworkingenvironment–theharshertheconditions,themoreoftenyouneedtoinspect.

3. Slingservicelife–basedonyourexperienceinusingslings.

It’s a good idea for the person handling the slings to visually inspect all slings before each lift. Additional inspections should be performed at least annually by a qualified designated person and permanent records kept.

OSHA specifies, “Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a competent person designated by the employer. Additional inspections shall be performed during sling use, where service conditions warrant.” In other words, you should visually inspect your sling before each lift.

when to replace slingsRemove all slings, including Flexi-Grip® round slings, from service if you see damage such as the following, and return to service only when approved by a designated person. These are removal criteria established by ANSI B30.9:

1. Acidorcausticburns.2. Meltingorcharringofanypartofthesling.3. Holes,tears,cutsorsnags.4. Brokenorwornstitchinginload-bearingsplices.5. Excessiveabrasivewear.6. Knotsinanypartofthesling.7. Excessivepittingorcorrosion,orcracked,distortedor

brokenfittings.8. Othervisibledamagethatcausesdoubtastothestrengthof

thesling.9. Missingorillegibleslingidentification.

In addition, we recommend three other important reasons to remove slings from service:

1. AnytimeyouseeourRed-Guard®warningyarns.

2. Distortionofthesling.

3. Anytimeaslingisloadedbeyonditsratedcapacityforwhateverreason.

While most of these standards are very specific regarding reasons for removal, others require your good judgment. The critical areas to watch are wear to the sling body, the selvage edge of webbing and the condition of the sling eyes.

Repair guidelinesIt’s never enough to give slings temporary repairs. Always follow these guidelines:

1. Damagedslingsshouldberepairedonlybyaslingmanufacturer.Ifthatisn’tpossible,therepairmanshouldcertifyinwritingthesling’sratedcapacity.

2. Slingsrepairedbyamanufacturermustbeproof-testedtotwicethedesignatedratedcapacityonthetagbeforereturningittoservice—andbackitupwithacertificateoftheproof-testing.

3. Inspectionrecordsforindividualslingsthathavebeenrepairedshouldbeupdatedwithalltherelevantinformationsuchasthecircumstancesinvolvedandproof-testing.

our synthetic web products measure up.Our synthetic web products don’t merely meet our own strict standards for workmanship and performance. They also meet or exceed these military and federal specifications:

1. ANSI Standard Z1.8 – specifications of general requirements for a quality program.

2. MIL-Standard-105 – sampling procedures and tables for inspection by attributes.

3. MIL-W-4088F – military specification for textile webbing —woven nylon.

4. MIL-W-23223A – military specification for slotted nylon webbing.

5. Fed. Spec. VT-285-E – federal specification for polyester thread.

6. Fed. Spec. VT-295-E – federal specification for nylon thread.

In addition, all work conforms to standards established by the following national safety institutions and their respective regulations:

• American National Standards Institute (ANSI) B30.9 Safety Standards for Cranes, Derricks, Hoists, Hooks, Jacks and Slings.

• Occupational Safety and Health Administration (OSHA) 1910.184 Standards for Slings.

Synthetic Web Handbook

Identifying wear and abuse.These are some of the most common types of web sling damage

caused by abuse and misuse. When you see any of these

problems during your regular inspection, stop. Replace the sling

immediately because the damage is done. Never attempt to

mend the sling yourself and, more so, never attempt to lift with

these slings.

Whether a sling is damaged from improper use or normal wear,

the same rule applies in all cases: Always cut the sling eyes and

discard the sling right away when you see damage. Only with

properly working slings can you take a load off your mind.

Tensile break

The distinguishing sign of a tensile break is a frayed appearance

close to the point of failure or damage. This usually happens when

a sling is loaded beyond its existing strength. The photo shows an

example of a sling pulled to destruction on a testing machine. You

can avoid tensile breaks by never overloading your sling.

Cut

You can easily see a cut in your sling when you see a clean break

in the webbing structure or fibers. This usually results when a sling

contacts a sharp object or unprotected edge of a load. This can

happen anywhere on the sling body or eyes. Many slings feature

Red-Guard warning yarns to alert you of serious cuts. One way

you can avoid cuts from contacting sharp corners is to use wear

pads on the sling to protect the fabric. See page 7 for details.

Cut and tensile damage

A good example is the photo shown here. It shows what can

happen when you use a sling that’s already been cut by a sharp

object along one edge of the sling body. The cut dramatically

reduces lifting capacity, and continued use will ultimately lead to

sling failure, usually at a load far below the sling’s rated capacity.

The solution, obviously, is to never use a sling after it’s been cut.

Abrasion damage

Anytime you see frayed fibers on the surface exposing the

“picks,” or cross fibers, of the webbing that hold the load-

bearing (lengthwise) fibers in place, it’s abrasion damage.

The most common abrasion damage occurs either when the

sling slips while in contact with a load during a lift or when

the sling is pulled from under a load. When you see the Red-

Guard warning yarns exposed, it’s your signal that serious

damage — and loss of lifting capacity — has occurred. We

recommend that slings with any damage to load-bearing fibers

be discarded. Wear pads are one way to avoid this damage.

Acid damage

It’s true nylon and polyester webbing are stable when exposed

to many common chemicals, but they should never be exposed

to any strong acids or corrosive liquids whenever possible. The

same is true for metal fittings on slings.

Example 1 (top photo). This is what happens when sulfuric

acid, like car battery acid, is heated to the boiling point and

dropped on nylon webbing. The charring on the surface fibers

deteriorates the sling and will continue to get worse, severely

affecting the webbing strength.

Example 2 (bottom photo). This is what happens when nylon

webbing is immersed in sulfuric acid at room temperature

for three weeks, resulting in major damage. Note the fibers

are softened and swollen, and the entire fabric is grossly

distorted, virtually destroying the webbing. You can help

prevent this damage by never storing slings in areas where

they may be exposed to acid or acid fumes, which are as

destructive as liquid.

The life and strength of Grade 80/100 chain slings depend on proper inspection, maintenance and use. For additional information, refer to ANSI B30.9 and OSHA 1910.184.CAREChain requires careful storage and regular maintenance.

• Store chains on an A frame in a clean, dry place.• To avoid corrosion, oil chains before prolonged storage.• Do not heat Alloy lifting chains; this will alter its thermal treatment.• Do not plate or change surface finish of chain. Contact us for special requirements.

USETo protect both operators and materials, observe these precautions when using chain slings:

• Before use, inspect chain and attachments following the instructions under “INSPECTION” below.• Do not exceed working load limit. Any of the factors listed here can reduce the load the chain will hold:

○ Acceleration in rate of load application – can produce dangerous overloading.○ Variation in the angle of the load to the sling – as the angle decreases, the working load of the sling will increase.○ Twisting, knotting or kinking – subjects links to unusual loading, decreasing the working load of the sling.○ Use for purposes other than those for which slings are intended – can reduce the working load of the sling.○ Free chain of all twists, knots and kinks.○ Center load in hook(s); hook latches must not support load.○ Avoid sudden jerks when lifting and lowering.○ Balance all loads; avoid tipping of loads.○ Use pads around sharp corners.○ Do not drop load on chains.○ Match the size and working load limit of attachments such as hooks or rings to the size and working load limit of the chain.○ For overhead lifting, use only alloy chain and attachments (Grade 80/100).

INSPECTIONIt is important both to inspect chain slings regularly and to keep a record of all chain inspections. Follow this guide for such an inspection system.

• Before inspecting, clean chains with a non-acid/non-caustic solvent so that marks, nicks, wear and other defects are visible.• Inspect each link for these conditions to remove from service:

○ Twists or bends.○ Nicks or gouges.○ Excessive wear at bearing points.○ Stretch.○ Distorted or damaged master links, coupling links or attachments especially spread in throat opening of hooks.

• Mark plainly with paint each link or attachment showing any of the conditions listed here to indicate rejection; remove from service until properly repaired.

* * Working load limit: The working load limit is the maximum load in pounds which should never be applied to chain, even when chain is new, and when load is uniformly applied in di-rect tension to a straight length of chain. * *

GENERAL CHAIN WORKING LOAD LIMITSBelow is a chart of the working load limits of Grade 30 through Grade 100 chain.

CHAIN SELECTION & WORKING LOAD LIMITSUnderstanding the working load limit of chain and chain slings is critical when choosing the best option for your application. This section details the working load limits of chain and chain slings, as well as explains how the working load limit is affected by temperature and lifting angles.

CHAIN & SLING GENERAL INSPECTION

It is important to inspect chain and chain slings regularly and to keep a record of all chain inspections. Follow the steps below when developing your inspection requirements and tracking system.

Before inspection, clean the chain so that marks, nicks, wear and other defects can be seen. Use a non-acid/ non-caustic solvent. Each chain link and sling component should be individually inspected for the conditions noted below.

1. Excessive wear and corrosion at chain and attachmentbearing points. Refer to page 16, “Wear Allowance chartfor Alloy grade 80 and 100 chain”. The table should alsobe used as a guide when inspecting coupling links.

2. Nicks or gouges

3. Stretch or link elongation

4. Twists or bends

5. Distorted or damaged links, master links, coupling linksor attachments, especially spread in throat openingof hooks. (Refer to other sections in this catalog forinspection guidelines regarding distortion and wearof hooks, master links and Hammerloks® .)

When inspecting chain slings specifically, it’s important to note that damage is most likely to occur in the lower portion of a sling. Therefore, particular attention should be given to those sections.

Each link or component having any condition listed above is to be marked with paint to clearly indicate rejection. Since any of the above noted conditions can affect chain performance and/or reduce the chain strength, chains and chain slings containing any of the conditions should be removed from service. A qualified person should examine the chain, assess the damage, and make a decision on whether or not repair is necessary before returning it to service. Extensively damaged chain should be scrapped.

Because of its use in critical lifting applications, repair of alloy chain should only be done by an authorized chain sling repair station. Nicks and gouges can be removed from the chain by a qualified person as instructed in the “Nicks and Gouges” section on this page.

CHAIN & SLING IN-DEPTH INSPECTION

Since Grade 80 and 100 chains are used for overhead lifting, and used frequently as part of a sling component, a more detailed and in-depth inspection in necessary.

TWISTING & BENDINGTwisted and bent links are relatively easy to recognize and affect chain performance significantly. Twisting and bending of links results from use of slings around sharp corners without padding, use of links with grab hooks under certain adverse conditions, and from loading of chain that is twisted, knotted, or kinked. (Refer to Hook Section for a more information on grab hooks.)

Consider that chain is evaluated by applying loads in a pure tensile link end-to-link-end fashion and rated accordingly. Bent or twisted links alter this normal loading pattern significantly and thus alter inner link stresses accordingly. For this reason all chain containing twisted or bent links must be removed from service.

NICKS & GOUGESThe outsides of links are exposed to contact with foreign objects that can cause damage. Nicks and gouges frequently occur on the sides. Therefore, they usually are located on surfaces under compressive stress and their potentially harmful effects are reduced.

The unique geometry of a chain link tends to protect tensile stress areas against damage from external causes. Figure 1 shows that these tensile stress areas are on the outside of the link body at the link ends where they are shielded against most damage by the presence of interconnected links. Tensile stress areas are located also on the insides of the straight barrels, but these surfaces are similarly sheltered by their location. However, gouges cause localized increases in the link stress. They can be harmful if they are located in areas of tensile stress and particularly so if they are perpendicular to the direction of stress. Refer to Figure 1.

Figure 2 shows nicks of varying degrees of severity. Reading clockwise, at three o’clock there is a longitudinal mark in a compressive stress area. Since it is longitudinal and located in a compressive stress area, its effect is mitigated, but good workmanship calls for it to be ground out. At about five o’clock there is a deep

will dictate their severity.

CHAIN & SLING INSPECTION GUIDETo ensure long life and continued strength of chain, it is important that the product is properly used, inspected and maintained. This section provides details on chain and chain sling inspection methods as well as the proper use and care of chain or slings. Following these guidelines will ensure safe and long use of products.

In addition to what is provided in this section, ASME and OSHA have specific regulations related to chain and chain sling use. For detailed information, refer to ASME B30.9 and OSHA 1910.184

transverse nick in an area of high shear stress. A similar nick is located at six o’clock in the zone of maximum tensile stress. Both of these can create a potentially dangerous escalation of the local stress and must be filed out. A nick that was located at eight o’clock has been filed out properly. Although the final cross section is smaller, the link is stronger because the stress riser effect of the notch has been removed. The remaining cross section can now be evaluated for acceptability by measuring it and applying the criterion for worn chain. See “Wear Allowances Table” below.

WEAR & CORROSIONCorrosion results in a reduction of link cross-section and can be detected using the same criteria as that for wear. Wear can occur in any portion of a link that is subject to rubbing contact with another surface. The natural shape of chain confines wear, for practical considerations, to only 2 areas. These are, in order of importance, (a) at the bearing points of interlink contact, and (b) on the out-sides of the straight side barrels which may be abraded from dragging chains along hard surfaces or from under loads. Figure 3 illustrates the condition of interlink wear and shows how to inspect for it. Notice how easily such wear can be detected by collapsing the chain to separate each link from its neighbors.

When wear is observed, the next step is to determine how severe the damage is and if the chain can still be safely used. To determine this, make a caliper measurement across the worn section of chain and compare it to the minimum allowable dimension for that chain. See the chart below for minimum section dimensions or wear allowances for Grade 80 and 100 Chain.

CHAIN INSPECTIONThe strength of welded link chain is relatively unaffected by a mod-erate degree of wear. The reason for this will be understood better if we take a brief look at the pattern of stress distribution in a chain link supporting an axial tension load.

Figure 4 shows in exaggerated manner the change in shape that takes place under such loading conditions. Note that the ends move farther apart while the side barrels move closer together. If the link were in a neutral stress condition to start with, the loaded link shown in broken outline would contain stresses of compression and tension. This is clearly illustrated in Figure 5 showing an inflated inner tube which is sustaining a load in the manner of a chain link. The wrinkled sections clearly indicate the areas of compression.

Figure 1 on the previous page shows the location of these stresses in a chain link. Tensile stresses are represented by arrows pointing away from each other, and compression stresses are depicted by arrows pointing toward each other. Notice that the bending, which occurs when link elongation takes place, induces compressive stresses at the interlink bearing surfaces and on the outside surfaces of the side barrels. Therefore, we see that these surfaces, which are the potential wear areas, play a lesser role in supporting the tensile load on the chain. For that reason, some amount of interlink or side barrel wear can occur before chain tensile strength decreases significantly.

Corrosion will generally be exhibited in the form of rusting and pitting. Rusted chain with a smooth unpitted surface finish can remain in service provided that the minimal section dimensions or wear allowances published by the chain manufacturer are complied with. However, visually discernible pitting should be carefully inspected using the technique outlined for “Nicks and Gouges”, paying particular attention to areas of tensile stress.

Alloy steel sling chain typically exhibits well over 20% elongation before rupture. The combination of elongation and high strength provides energy absorption capacity. However, high elonga-tion or stretch, by itself, is not an adequate indicator of shock resistance or general chain quality and should not be relied upon by riggers to provide advance warning of serious overloading and impending failure. Overloading must be prevented before it happens by selection of the proper type and size of slings.

STRETCH & CHAIN ELONGATION A visual link-by-link inspection is the best way to detect dangerously stretched links. The smallest sign of binding or loss of clearance at the juncture points of a link indicates a collapse in the links’ sides due to stretch. Any amount of stretch indicates overloading, and the chain should be removed from service.

Note that a significant degree of stretch in a few individual links may be hidden by the apparent acceptable length gage of the overall chain. This highlights the importance of link-by-link inspection.

There is no short-cut method that will disclose all types of chain damage. Safety can only be achieved through proper inspection procedures. There is no adequate substitute for careful link-by-link scrutiny.

Proper use of Wire Rope Clips1. Refer to the chart above in following these instructions. Turn back specified amount of rope from

thimble or loop. Apply first clip one base width from dead end of rope. Apply U-bolt over dead end of wire rope - live end rests in saddle. Tighten nuts evenly, alternate from one nut to the other until reaching the recommended torque.

2. When two clips are required, apply the second clip as near the thimble or loop as possible. Tighten nuts evenly, alternating until reaching the recommended torque. When more than two clips are required, apply the second clip as near the loop or thimble as possible, turn nuts on second clip firmly, but do not tighten. Proceed to Step 3.

3. When three or more clips are required, space additional clips equally between the first two - take up rope slack - tighten nuts on each U-bolt evenly, alternating from one nut to the other until reaching the recommended torque.

4. Apply an initial load equal to loads expected in use. Inspect for proper orientation and spacing of clips and retighten the nuts to recommended torque.

WARNINGImproper installation and use of

wire rope clips can result in injury. To avoid injury:

Install and use only as instructed herein.
