Quality toInternational
StandardsWe work closely with our steel suppliers to ensure that the raw material meets our stringent specification.
We also work closely with our world markets and have official approval by the main national and international authorities, including; MOD, NATO, BG, and many others. All Gunnebo Lifting G80 and G100 Alloy Chains are manufactured and tested to the requirements of ISO 1834 & 3076, 1984, and BS 4942, Parts 1 & 5, 1984. ASTM, A391 and A906, and NACM 90. Gunnebo Lifting G80 and G100 Alloy Chains are randomly subjected to bend testing across the weld to check material ductility and weld integrity. The link bend test is accomplished in the finished condition and meets test requirements of the EN 818 Standard. All components are matched to the Working Load Limits of the relevant chain size.
All G80 and G100 Alloy Chains, and Alloy components meet or exceed the safety standards as prescribed by AISI B30-9 and OSHA 1910-184 for slings. Our Ramnas factory is approved by Lloyd’s (LRQA) for quality assurance to ISO 9001. Our quality management covers all aspects of production from raw material to delivered product. L R Q A approval for our system includes design, development, manufacturing, marketing, and distribution of lifting chains and associated components.
Full Test Certification is supplied on request.

Safety Put to the Test.
All chain and every single component is proof-
loaded to a level that corresponds to 2 1/2 times
WLL. Individual inspection before delivery from our
factories ensures high and consistent quality.
Chain and components are tested to destruction on a
random sample basis from every production batch. Minimum breaking force = Maximum working load limit x Design Factor. Full test data is
documented. The prescribed elongation for Gunnebo
Lifting G80 and G100 Alloy chains is minimum 20%.
Additionally, finished products are subjected to testing to
ensure the correct hardness levels. Cyclical loading tests are
also carried out to simulate the fatigue effects that would be
expected over many years of use.
Chain and components carry identification marks for full
traceability back to the steel supplier for raw material analysis.

Basic chain sling configurations are often described using a code. Naming conventions have many exceptions and may vary among manufactures. 1. First Letter often designates the number of legs or branches: S Single leg with one branch D Double leg with two branches T Triple leg with three branches Q Quadruple leg sling with four branches 2. Second letter normally designates the fitting at the top of the sling: O Oblong shaped master link S Sling hook G Grab hook B Basket with oblong master sling
3. Third letter or group of letters normally designates the fitting at the bottom of each branch. A few of the many possibilities are listed below. S Sling hook G Grab hook LK Sliding choker BK Self Locking F Foundry hookIf A precedes the group of letters, then a device to adjust the length has been added. Adjusters can be either of two styles, Type A or Type B. Both are pictured.
Example: ADOS describes an Adjustable, Double Leg Sling with Oblong master link on top and a Sling hook at the bottom of each leg or branch.

1. Single Leg Sling: If the required measurement falls in the middle of a link, the next link is cut.
2. Double Leg Sling (when assembling a clevis system sling) Cut chain to length and count the links. You must have an even number of links so hooks hang in the correct plane. (Hooks should always point out, as shown in diagram.)
3. Triple or Quadruple Leg Sling (when assembling a clevis system sling) Cut chain to length and count the links. You must have an odd number of links so hooks hang in the correct plane. (Hooks should always point out, as shown in diagram.) If the measurement falls in the middle of a link, the next link is cut.
4. A metal I.D. Tag must always be attached to a chain sling, showing serial number, size, reach, rated capacity at angle of lift and manufacturer.
5. The reach of the sling is the length measured from the load bearing surface of the master link to the load bearing surface of the hook or lower terminal (as shown in illustration).
6. Each sling manufactured shall have a completed certificate of test provided to user.
Tips for Chain Sling Assembly
INFORM A RIGGER - PASS THE WORD
30
• Never use a sling without training…OSHA regulation
requires responsible work practice.
“The employer shall permit only those employees
qualified by training or experience to operate equipment or
machinery” – OSHA 1926.20 (b)(4).
Employee training should include information given in
OSHA training literature, ASME B30.9 – 2003 “Slings” and
ASME B30.10 – 2005 “Hooks” Safety Standards, and this
document.
• Always inform yourself… Ask your employer for chain
sling safe use instruction.
“The employer shall instruct each employee in the
recognition and avoidance of unsafe conditions and the
regulations applicable to his work environment to control or
eliminate any hazards or other exposure to illness or injury”
– OSHA 1926.21 (b)(2).
• Always comply with applicable Federal and local
regulations …Federal and local regulations govern worksite
activity.
Understand all governing laws and safety standards before
use of chain slings. OSHA 1910.184 regulates chain sling
safe operating practices, product identification, inspection
requirements, and use limitations. ASME B 30.9-2003
“Sling” safety standard provides additional recommendations
for chain sling use.
“If a particular standard is specifically applicable to a
condition, practice, means, method, operation, or process, it
shall prevail over any different general standard…” – OSHA
1910.5(c)(1).
Contact OSHA at (800) 321-6742, or www.OSHA.gov and
ASME at (800) 843-2763, www.ASME.org for reference
assistance.
• Always know load weight… Avoid sling failure.
“The rated load of the sling shall not be exceeded.” – ASME
B30.9-1.10.1 (c).
Weight of the load to be lifted must be known for
determination of proper sling configuration and working
load limit.
• Never use a sling without a legible identification tag…Sling
Identification is required to ensure proper sling application.
“Alloy steel chain slings shall have permanently affixed
durable identification stating size, grade, rated capacity, and
reach.” - OSHA 1910.184 (e) (1)

Standard Gunnebo Lifting Working Load Limits
(WLL) are based on a 4 design factor. Lift
dynamics, duty cycle and hitch type may require
an increased design factor, hence a reduced WLL.
Inattention to required design factor can result
in sling overload. Contact Gunnebo Johnson
Corp. Service Department for assistance at
(800) 331-5460.
Sling WLL depends on sling leg angle. The WLL
for a sling is reduced as the sling leg angle with
the horizontal gets smaller. This fact applies to
all multi-leg and basket slings and must not be
ignored.
The following diagram illustrates the effect of sling
leg angle on the WLL for a single basket and 2-leg
sling.
The WLL of a sling with a 30° leg angle is 50%
of the WLL for the same sling with a 90° leg
angle. Inattention to the effect of sling leg angle
can result in sling overload.
Chain sling WLL is to be reduced in accordance
with TABLE 5 when chain is rigged over an
edge radius (R) less than two (2) x the chain rod
diameter (d).
Reduced WLL equals chain sling WLL from
identification tag x reduction factor.
• Never ride on sling or load ... Avoid death or
injury.
Sling use regulation requires: “All employees shall
be kept clear of loads about to be lifted and of
suspended loads.” - OSHA 1910.184 (c) (9).
General worksite regulations require “No hoisting,
lowering, swinging or traveling shall be done while
anyone is on the load or hook assembly.” - OSHA
1910.180 (h) (3) (v).
Construction worksite regulation stipulates: “The
use of a crane or derrick to hoist employees on a
personnel platform is prohibited except when the
erection, use, and dismantling, of conventional
means of reaching the worksite, such as a personnel
hoist, ladder, stairway, aerial lift, elevating work
platform or scaffold, would be more hazardous
or is not possible because of structural design or
worksite conditions.” - OSHA 1926.550 (g) (2).
Alloy steel chain slings shall not be used to rig
personnel platforms.
• Never rig a sling to a load improperly ... Avoid
dropped loads and sling damage.

For more than 200 years, satisfied customers have counted on the Gunnebo Lifting name – and the attributesthat go with it. Innovation. Durability. Reliability. Quality. Value. The Gunnebo Lifting name represents a tradition of manufacturing excellence and an unequaled commitment to research, testing, and rigorous safety assurance. The bottom line is: when you specify Gunnebo Lifting chain and components, you get the best you can buy. Until recently, you could easily identify the renowned Gunnebo Lifting brand of lifting components by the distinctive bright yellow coating. Now other brands have begun to paint their products yellow. However, as one of our customers said: “just because it’s yellow doesn’t mean it’s Gunnebo Lifting.” For the highest quality chain, hooks, links, and other lifting components, ask for the original. Gunnebo Lifting.
