TESTING AND INSPECTING SLINGS AND FITTINGS 1.0 Purpose p.

The purpose of this section instruction letter is to specify the procedure and acceptance criteria for testing and inspecting slings, i

e

~

fit tings and lif ting devices'. ---- - ------ - -- - ~

f 2.0 Aoplicability This pr.,cedure is applicable when required by the maintenance super-

{

visor to Last and/or inspect any sling or fitting which needs certification that it is capable of lifting a specific load, 3.0 References

3.1 ANSI B30.9 - 1971

['

4.0 Definitions 4.1.

nele of Loading--Inclination of a leg or branch of a sling measured from either the horizontal or vertical plane. When angle of loading is less than 5 degrees from the vertical the

-load may be considered a vertical load.

L 4.2 Bridle Wire Rope Sling--A sling composed of multiple legs with the top ends gathered in a fitting that goes over the lifting hook.

- f' 4.3 Hand Tucked--The rope ends are hand tucked into the body thus forming the core. Four tucks are required and no sleeres are used.

4.4 Hitch. Basket--Loading with sling passed under the load with both ends, end attachments, eyes, or handles on the hook or a single master link.

4.5 Hitch. Choker--Loading with sling passed through one end attachment, g-eye or handle and suspended by the other.

4.6 Hitch, Vertical--Loading with the sling vertical. Load suspended.

on a single part or leg.

4.7.2 Single leg slings with end fittings - Measured from pull of

-J 2/29/80 4.7.3 Multiple leg slings - Same as 4.7.2 except that the master or similar fitting is not included in the length dimension.

-F 4.8 Link, Master (Cathering Ring)--Forged or welded steel link used to support all members (legs) of a wire rope sling.

a 4.9 Proof Load--The specific load applied in the performance of the proof test.

4.10 Proof Test--A nonde,structive _ tension test made by the sling manufacturer to verify construction and workmanship of the individual sling.

J l

4.11 Rated Capacity (Working Load Limit)--The maxinum allowable working load established by the sling manufacturer.

y 4.12 Safety Factor--Ratio between nominal or minimum breaking strength and rated capacity of the sling (minimum of 5).

4.13 Sline Manufacturer--A person or company assembling sling ccmponents

..g I

into their final form for actual use.

The sling manufacturer and

-o the manufacturer of the sling material may or may not be identical.

[

4.14 Strand Laid Rone--A wire rope made with strands (usually 6 or 8)'

formed around a fiber corn, wire strand core, or independent wire rope core (IWRC).

-l 4.15 Streneth. Minimum Breaking-Minimum load at which the sling will braak when loaded to destruction in direct tension.

1:

4.16 Strencth. Nominal Breaking--Load at which the sling could-be expected to break when loaded to destruction in direct tension.

{

4.17 Taeline--A restraining line to control position of the load.

5.0 Resnonsibilities E

The maintenance supervisor is responsible for implementation of this

~

procedure.

Craft foremen are responsible for performing the testing and g

inspection outlined in this procedure and the recording of all required t.

data.

Craft foremen are also responsible for ensuring slings are cleaned, straightened, not abused and returned to their proper storage location as listed in Appendix D.

CSSC slings and shackles will be cheched out by p

dompleting an Appendix B check out log form.

6.0 Proof Testing and Sline Insoection and Replacement

.6.1 Proof Testing--All slings and fittings used for lifting CSSC equipment shall be proof tested. When new slings are purchased from an outside e-4 vendor proof testing certifications shall be requested. An appendix

' [

A prooftesting data sheet shall be completed for each CSSC sling and fitting.

from Appendix C or from the sling manufacturer and a.

record on data sheet.

E l" 6.1.1.2 Calculate the proof load range for each. Proof load range = (1.5 x rated capacity) to (2.0 x rated capacity).

m -'

"- --- whose weight is known by calculations, drawings, manuals,

-,A etc., and is in the proof load range calculated in

.I step 6.1.1.2 or use a load cell to determine the test weight. Record. description of weight or test equipment on data sheet.

T-6.1.1.4 Attach the sling to the test weight and lift the test weight until it clears the floor and hold sufficiently

}-

to visually examine the sling for physical damage. Record on data sheet the sling test results.

'5 Acceptance Criteria--If the sling lifts the test weight l

and holds it for the duration of the test without any apparent physical damage, the sling is acceptable.

}-

6.1.1.5 Release the sling from the weight and complete and attach a tag similar to the one in Appendix B to the sling.

6.1.2 L.

Alternate Method for Prooftesting Multiple Leg Bridle Slings 6.1.2.1 The prooftesting of the multiple leg bridle slings shall

guidelines)

Conditions such as the following are sufficient reason

.T to reject a sling or fitting 6.2.2.1.Six randomly distrubuted broken wires in one rope lay or three broken wires in one

_ strand in one rope lay.

[l 6.2.2.2 Wear or scraping of one-third the original diameter of outside individual wires.

6.2.2.3 Kinking, crushing, bird caging or any other

'T d** age resulting in distortion of the rope structure.

6.2.2.4 Evidence of heat damage, w

6.2.2.5 End attachments that are< cracked, deformed, or worn.

s 3

6.2.2.6 Hooks that have been opened more than 15 percent of the normal throat onaning measured at the narrowast point or twisted more than 10 degrees from the plane of the unbent hook.

6.2.2.7 Corrosion of the rope or end attachments.

L_.

6.2.2.8 Fitting Defective, Pin Damaged or Lost.

'f 6.3 Replacement 6.3.1 When the aceptance criteria of step 6.2.2 are not 6

met the slint shall be destroyed and a new sling P'

ordered to replace the defective one. The new sling shall be assigned the defective sling's number followed ~

-j by a sequential letter of the alphabet. For example

,b if the "C-S-000" sling is destroyed the new sling number will be "C-S-000A".

7.1.13 Do not pull a sling from under a lond when the loed is resting r'.

on the cling. Block the load up to remove.

L*:.

~

7.1.14 Do not shorten a sling by knotting, by wire rope clips, or by e.ny other means.

y?

L.

7.1.15 Do not inspect a sling by pessing bare hands over the body.

Broken wires, if present, may puncture the hends.
