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 />

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 />

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 />
