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)

Alloy Steel Chain Sling Warnings and Use LimitationsThis document contains warnings and use limitation information applicable to Gunnebo Lifting Grade 80 & Grade 100 Alloy Steel Chain Slings and components and is furnished with all Gunnebo Johnson Corp. shipments. Component distributors and lift system manufacturers must pass on this information in their warnings and use limitation literature where Gunnebo Lifting components are involved.

“Hooks, rings…or other attachments shall have

a rated capacity at least equal to that of the alloy

steel chain with which they are used or the sling

shall not be used in excess of the rated capacity

of the weakest component…” – OSHA 1910.184

(e) (2) (i)

“Makeshift links or fasteners…shall not be used.”

– OSHA 1910.184 (e) (2) (ii)

Gunnebo Johnson Corp. provides a blank identification

tag, attached by a coupler, to be stamped with sling

WLL, minimum working range angle, serial number,

chain size, grade, reach, type and manufacturer. Order

547303 for replacement.

Grade of component with the lowest breaking

strength shall be specified on the identification tag.

Nonstandard grades shall be designated by “NS.”

Working Load Limit (WLL) is the maximum working

load for a specified working range. Sling working

range includes sling leg angles from 90° to a specified

minimum. The specified minimum working range

angle is given on the identification tag.

Working load is to be applied vertically to a sling

assembly having symmetric leg angles. WLL applies

to loads lifted vertically and does not include torsional,

binding, shock or non-symmetrical load effects.

Gunnebo Lifting Grade 80 & Grade 100 Alloy Steel

Chain Straight Leg and Basket Sling Working Load

Limits for selected working ranges of symmetric sling

leg angles are listed in pounds and given in TABLE 1A

& 1B. No chain sling shall be rigged with a leg angle

less than 30° from the horizontal.

“Slings containing any Grade 80 components shall be

rated at Grade 80 WLL’s.” ASTM A906/A 906M –02-

9.2.

Double Leg and Single Basket Sling WLL for an

alternate working range of symmetric sling leg angles

equals (=) 2 x TABLE 1A or 1B single leg WLL x sine

of the minimum working range angle.

Triple and Quadruple leg and Double Basket Sling

WLL for an alternate working range of symmetric sling

leg angles equals (=) 3 x TABLE 1A or 1B single leg

WLL x sine of the minumum working range angle.

TABLE 2 lists for convenience sine values for selected

sling leg angles.

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.
