Your Partner<br />

in Safe Lifting<br />

The Gunnebo<br />

BKLK Ball<br />

Bearing Swivel<br />

Safety Hook<br />

Think Gunnebo when selecting<br />

lifting chain and components. Lifting<br />

is our business. Gunnebo has<br />

become known for quality, down<br />

to the smallest component, as a<br />

result of over 200 years experience,<br />

combined with systematic<br />

quality control and our own<br />

research and development<br />

laboratories.<br />

Chain and components<br />

are made from quenched and<br />

tempered alloy steel. A guarantee<br />

for very high strength, low weight,<br />

high wear resistance and long life. All Gunnebo G8<br />

components are uniformly marked with equivalent chain<br />

size, grade and manufacturer’s designation for positive identification.<br />

Quality to International Standards<br />

Swivel hook<br />

built with ball<br />

bearings. Full<br />

swivel action<br />

under load<br />

Rear trigger release<br />

provides easy to<br />

work protection<br />

Heat number<br />

identification<br />

allows full product<br />

traceability


All chain and every single component is<br />

proof-loaded to a level that corresponds to 62% of<br />

the minimum breaking load. Individual inspection<br />

before delivery from our factories ensures high and<br />

consistent quality.<br />

Chain and components are tested to<br />

destruction on a random sample basis from every<br />

production batch. Minimum breaking force =<br />

Maximum working load limit x Design Factor.<br />

Full test data is documented. The prescribed<br />

elongation for Gunnebo Grade 80 Alloy chain is<br />

minimum 20%.<br />

Additionally, finished products are subjected to<br />

testing to ensure the correct hardness levels. Cyclical<br />

loading tests are also carried out to simulate the fatigue<br />

effects that would be expected over many years of use.<br />

Chain and components carry identification marks<br />

for full traceability back to the steel supplier for raw<br />

material analysis.<br />

Safety Put to the Test.<br />

Quality to<br />

International<br />

Standards<br />

We work closely with our steel suppliers to<br />

ensure that the raw material meets our stringent<br />

specification.<br />

We also work closely with our world<br />

markets and have official approval by the main<br />

national and international authorities, including; MOD,<br />

NATO, BG, and many others.<br />

All Gunnebo Grade 80 Alloy Chain is<br />

manufactured and tested to the requirements of ISO<br />

1834 & 3076, 1984, and BS 4942, Parts 1 & 5, 1984.<br />

ASTM, A391 and A906, and NACM 90. Gunnebo<br />

Grade 80 Alloy Chain is randomly subjected to bend<br />

testing across the weld to check material ductility and<br />

weld integrity. The link bend test is accomplished in<br />

the finished condition and meets test requirements of<br />

the EN 818 Standard. All components are matched<br />

to the Working Load Limits of the relevant chain size.<br />

All Gunnebo Grade 80 Alloy Chain and Alloy<br />

components meet or exceed the safety standards as<br />

prescribed by AISI B30-9 and OSHA 1910-184 for<br />

slings.<br />

Our Ramnas factory is approved by Lloyd’s<br />

(LRQA) for quality assurance to ISO 9001. Our<br />

quality management covers all aspects of<br />

production from raw material to delivered product.<br />

LRQA approval for our system includes design,<br />

development, manufacturing, marketing, and<br />

distribution of lifting chains and associated<br />

components.<br />

Tips for Chain Sling Assembly<br />

1. Single Leg Sling:<br />

If the required measurement falls in the middle of a link, the next link is cut.<br />

2. Double Leg Sling<br />

(when assembling a clevis system sling)<br />

Cut chain to length and count the links. You must have an even number of links so hooks hang in the<br />

correct plane. (Hooks should always point out, as shown in diagram.)<br />

3. Triple or Quadruple Leg Sling<br />

(when assembling a clevis system sling)<br />

Cut chain to length and count the links. You must have an odd number of links so hooks hang in the<br />

correct plane. (Hooks should always point out, as shown in diagram.) If the measurement falls in the<br />

middle of a link, the next link is cut.<br />

4. A metal I.D. Tag must always be attached to a chain sling, showing serial number, size, reach, rated capacity<br />

at angle of lift and manufacturer.<br />

5. The reach of the sling is the length measured from the load bearing surface of the master link to the load<br />

bearing surface of the hook or lower terminal ( as shown in illustration).<br />

6. Each sling manufactured shall have a completed certificate of test provided to user.<br />

Alloy Steel Chain Sling Warnings and Use Limitations<br />

This document contains warnings and use limitation information applicable to Gunnebo G80 Alloy Steel Chain Slings and<br />

components, and is furnished with all Gunnebo Johnson shipments. Component distributors and lift system manufacturers<br />

must pass on this information in their Warnings and Use Limitation literature where Gunnebo components are involved.<br />

24<br />

ALLOY STEEL CHAIN SLINGS<br />

WARNING<br />

CHAIN SLING FAILURE CAN CAUSE<br />

DEATH OR INJURY.<br />

SLING FAILURE RESULTS FROM<br />

MISUSE, DAMAGE, AND<br />

EXCESSIVE WEAR<br />

Protect yourself and others:<br />

• Never use a sling without training.<br />

• Always inform yourself…Ask your employer for the<br />

manufacturer’s sling use limitations.<br />

• Always comply with applicable Federal and local<br />

regulations.<br />

• Always know load weight.<br />

• Never use a sling without a legible rated load tag.<br />

• Never overload a sling.<br />

• Never ride on sling or load.<br />

• Never use an improper sling configuration.<br />

• Never use a worn-out or damaged sling.<br />

• Never use a sling in extreme temperatures.<br />

• Never use a sling in acidic conditions.<br />

• Never use a sling without training…OSHA regulation<br />

requires responsible work practice.<br />

“The employer shall permit only those employees qualified by<br />

training or experience to operate equipment or machinery” –<br />

OSHA 1926.20 (a)(4).<br />

Employee training should include information given in OSHA<br />

training literature, ASME B30.9 – 1996 “Slings” and ASME B30.10a<br />

– 1996 “Hooks” Safety Standards, and this document.<br />

• Always inform yourself… Ask your employer for chain sling<br />

safe use instruction.<br />

“The employer shall instruct each employee in the recognition<br />

and avoidance of unsafe conditions, and the regulations<br />

applicable to his work environment to control or eliminate any<br />

hazards or other exposure to injury” – OSHA 1926.21 (b)(2).<br />

Always comply with applicable Federal and local regulations<br />

…Federal and local regulations govern work site activity.<br />

Understand all governing laws and safety standards before use<br />

of chain slings. OSHA 1910.184 regulates chain sling safe<br />

operating practices, product identification, inspection<br />

requirements, and use limitations. ASME B30.9-1996 “Sling”<br />

Safety Standard provides additional recommendations for chain<br />

sling use.<br />

“If a particular standard is specifically applicable to a condition,<br />

practice, means, method, operation, or process, it shall prevail<br />

over any different general standard…” – OSHA 1910.5(c)(1).<br />

Call OSHA at (202) 523-3517 and ASME at (212) 705-7722 for<br />

reference assistance.<br />

• Always know load weight…Avoid sling failure.<br />

“The weight of the load shall be within the rated load of the<br />

sling.” – ASME B30.9-1.9(b).<br />

Weight of the load to be lifted must be known for determination<br />

of proper sling configuration and working load limit.<br />

• Never use a sling without a legible identification tag…<br />

Sling Identification is required to ensure proper sling application.<br />

“Alloy steel chain slings shall have permanently affixed durable<br />

identification stating size, grade, rated capacity, and reach.” -<br />

OSHA 1910.184 (e) (1)<br />

“Hooks, rings…or other attachments shall have a rated capacity<br />

equal to the alloy steel chain with which they are used or the<br />

sling shall not be used in excess of the rated capacity of the<br />

weakest component…” – OSHA 1910.184(e)(2)(1)


“Makeshift links or fasteners…shall not be used.” –<br />

OSHA 1910.184(e)(2)(ii)<br />

Gunnebo-Johnson provides a blank identification tag,<br />

attached by a coupler, to be stamped with sling WLL,<br />

minimum working range angle, serial number, chain<br />

size, grade, reach, type and manufacturer. Order<br />

547303 for replacement.<br />

Grade of component with the lowest breaking<br />

strength shall be specified on the identification tag.<br />

Nonstandard grades shall be designated by “NS.”<br />

Working Load Limit (WLL) is the maximum working<br />

load for a specified working range. Sling working<br />

range includes sling leg angles from 90° to a specified<br />

minimum. The specified minimum working range<br />

angle is given on the identification tag.<br />

Working load is to be applied vertically to a sling<br />

assembly having symmetric leg angles. WLL applies to<br />

loads lifted vertically and does not include torsional,<br />

binding, shock or non-symmetrical load effects.<br />

Gunnebo Grade 80 Alloy Steel Chain Sling Working<br />

Load Limits for selected working ranges of symmetric<br />

sling leg angles are listed in pounds and given in<br />

TABLE 1. No chain sling shall be rigged with a leg<br />

angle less than 30° from the horizontal.<br />

Double Leg Sling WLL for an alternate working range<br />

of symmetric sling leg angles equals (=) 2 * TABLE 1<br />

single leg WLL * sine of the minimum working range<br />

angle.<br />

Triple and Quadruple Leg Sling WLL for an alternate<br />

working range of symmetric sling leg angles equals<br />

(=) 3 * TABLE 1 single leg WLL * sine of the minimum<br />

working range angle.<br />

• Never overload a sling…Understand Working<br />

Load Limits.<br />

“Slings shall not be loaded in excess of their rated<br />

capacities.” – OSHA 1910.184 (c)(4).<br />

26<br />

“Rated loads for alloy steel chain slings shall be based<br />

on a minimum design factor of 4.” – ASME B30.9-1.2<br />

Standard Gunnebo Working Load Limits (WLL) are<br />

based on a 4 design factor. Lift dynamics, duty cycle<br />

and hitch type may require an increased design factor,<br />

hence a reduced WLL. Inattention to required design<br />

factor can result in sling overload. Contact Gunnebo-<br />

Johnson Service Department for assistance at (800)<br />

331-5460.<br />

Sling WLL depends on sling leg angle. The WLL for a<br />

sling is reduced as the sling leg angle with the<br />

horizontal gets smaller. This fact applies to all multi-leg<br />

slings and must not be ignored.<br />

The following diagram illustrates the effect of sling leg<br />

angle on the WLL for a 2-leg sling.<br />

The WLL of a sling with a 30° leg angle is 50% of the<br />

WLL for the same sling with a 90° leg angle.<br />

Inattention to the effect of sling leg angle can result in<br />

sling overload.<br />

• Never ride on sling or load…Avoid death or injury.<br />

Sling use regulation requires: “All employees shall be<br />

kept clear of loads about to be lifted and of<br />

suspended loads.” - OSHA 1910.184 (c) (9).<br />

General work site regulations require “No hoisting,<br />

lowering, swinging or traveling shall be done while<br />

anyone is on the load or hook assembly.” - OSHA<br />

1910.180 (h) (3) (v).<br />

Construction work site regulation stipulates: “The use<br />

of a crane or derrick to hoist employees on a<br />

personnel platform is prohibited. Except, when the<br />

erection, use, and dismantling of conventional means<br />

of reaching the work site, such as a personnel hoist,<br />

ladder, stairway, aerial lift, elevating work platform or<br />

scaffold, would be more hazardous or is not possible<br />

because of structural design or work site conditions.”<br />

- OSHA 1926.550 (g) (2).<br />

Alloy steel chain slings shall not be used to rig personnel<br />

platforms.<br />

• Never rig a sling to a load improperly…Avoid<br />

dropped loads and sling damage.<br />

“Safe operating practices…” – OSHA 1910.184 (c)<br />

“Operating practices…” – ASME B30.9 1.9.<br />

• Sling leg angle shall not be less than 30° from the<br />

horizontal.<br />

• Slings shall be shortened with a shortening hook<br />

only, and not with knots or bolts or other makeshift<br />

devices.<br />

• Sling legs shall not be kinked or twisted.<br />

• Sling hooks shall not be point loaded.<br />

• Sling hook latch may be mandatory by regulation,<br />

safety codes, or insurance.<br />

• Slings used in a basket hitch shall have the loads<br />

balanced to prevent slipping.<br />

• Slings shall be securely attached to their loads.<br />

• Slings shall be padded or protected from the sharp<br />

edges of their loads.<br />

• Never use a worn-out or damaged sling.<br />

“Each day before being used, the sling and all fastenings<br />

and attachments shall be inspected for damage<br />

or defects by a competent person designated<br />

by the employer. Additional inspections shall be<br />

performed during sling use where service conditions<br />

warrant. Damaged or defective slings shall be immediately<br />

removed from service” - OSHA 1910.184 (d).<br />

“In addition to the inspection required by paragraph<br />

1910.184(d), a thorough periodic inspection shall be<br />

made on a regular basis, to be determined on the basis<br />

of (A) frequency of sling use; (B) severity of service<br />

conditions; (C) nature of lifts being made; and (D)<br />

experience gained on the service life of slings used in<br />

similar circumstances. Such inspections shall in no event<br />

be at intervals greater than once every 12 months.” -<br />

OSHA 1910.184(e)(3)(i).<br />

“The thorough inspection of alloy steel chain slings<br />

shall be performed by a competent person designated<br />

by the employer, and shall include a thorough inspection<br />

for wear, defective welds, deformation and<br />

increase in length. Where such defects or deterioration<br />

are present, the sling shall be immediately removed<br />

from service.” – OSHA 1910.184(e)(3)(iii).
