WARNINGS
ANY REPLACEMENT FASTENER (BOLTS, NUTS, CAP SCREWS, MACHINE SCREWS, ETC.) USED
DURING MAINTENANCE OR OVERHAUL MUST BE GRADE 8 OR EQUIVALENT UNLESS OTHERWISE
SPECIFIED.
WHEN RE-ASSEMBLING LOAD-BEARING DEVICES (CHAIN SLINGS, RIGID SLINGS, BACKUP LEGS,
ETC.) NOTE THAT THE ASSOCIATED FASTENERS MUST BE TIGHTENED TO THE CORRECT TORQUE
SPECIFIED FOR THAT SIZE OF FASTENER (SEE SECTION 3 - OVERHAUL). ANY THREADED FASTENER
IN A LOAD-BEARING DEVICE MUST BE SECURED WITH RED OR BLUE LOCTITE™.
A “LOAD-BEARING DEVICE” IS A CHAIN SLING, RIGID SLING, SPREADER BAR ASSEMBLY, FRAME, OR
ANY OTHER DEVICE THAT BEARS THE PARTIAL OR TOTAL WEIGHT OF THE EQUIPMENT FOR WHICH
THIS MANUAL HAS BEEN PRODUCED
THE LOAD-BEARING DEVICE SUPPLIED BY MCCOY DRILLING & COMPLETIONS IS DESIGNED TO SUP-
PORT THE EQUIPMENT DESCRIBED IN THIS MANUAL. MCCOY DRILLING & COMPLETIONS WILL NOT
GUARANTEE THE ABILITY OF THE LOAD-BEARING DEVICE TO SUPPORT ANY OTHER PART, ASSEM-
BLY OR COMBINATION OF PARTS AND ASSEMBLIES. MCCOY DRILLING & COMPLETIONS WILL NOT
GUARANTEE THE ABILITY OF THE LOAD-BEARING DEVICE TO LIFT OR SUPPORT THE EQUIPMENT
DESCRIBED IN THIS MANUAL IF THERE ARE ANY MODIFICATIONS TO THE LOAD-BEARING DEVICE,

1. Inspection Of Slings
McCoy Drilling & Completions strongly recommends the following practices:
Acompleteinspectionofnewload-bearingdevicesandattachmentsshallbeperformedbyaqualified,designatedpersonpriorto
initialuse.Eachlinkandcomponentshallbeexaminedindividually,takingcaretoexposeandexamineallsurfacesincludingtheinner
linksurface.Theslingshallbeexaminedforconditionssuchasthoselistedintheremovalcriteriabelow.Inaddition,dailyinspection
ofslings,fasteningsandattachmentsshallbeperformedbyadesignatedperson.Ifdamageordefectsarefoundateitherinspection,
thedamagedordefectivecomponentshallbequarantinedfromserviceuntilitcanbeproperlyrepairedorreplaced.
RemovalCriteria:
Aload-bearingdeviceshallberemovedfromserviceifconditionssuchasthefollowingarepresent:
• Missingorillegibleslingidentification.
• Cracksorbreaks
• Evidenceoftamperingisseen-slingtaghasbeenmodifiedorobscured,ortamper-proofnutsaremissing.
• Signsofimpactonload-bearingcomponents,includingspreaderbars,liftinglugs,rigidslings&rigidslingweldments,andlegs&
legmounts.
• Brokenordamagedwelds.
• Excessivewear,nicks,orgouges.Refertothechartbelowtoensureminimumthicknessonchainlinkssuppliedisnotbebelow
thevalueslisted:
• Stretched,bent,twisted,ordeformedchainlinksorcomponents.
• Evidenceofheatdamage.
• Excessivepittingorcorrosion.
• Lackofabilityofchainorcomponentstohinge(articulate)freely.
• Weldsplatter.
• Forhooks,removalcriteriaasstatedinASMEB30.10
• Otherconditions,includingvisibledamage,thatcausedoubtastothecontinueduseofthesling.
Inspectalllugsandfixingpointsforsignsofelongationand/orbending,orformaterialbuild-uparoundthehole.Repairorreplace
componentsthatappeardistorted.Ensureall hardwareistightandingoodcondition. Replacemissinghardwareifnecessary.All
hardwaremustbefreeofrustandcorrosion.
Additionalinspectionsshallbeperformedduringslingusewhereserviceconditionswarrant.Periodicinspectionintervalsshallnot
exceedoneyear.Thefrequencyofperiodicinspectionsshouldbebasedon:
• Frequencyofuseoftheload-bearingdevice.
• Severityofserviceconditions
• Natureofliftsbeingmade
• Experiencegainedontheservicelifeofload-bearingdevicesusedinsimilarcircumstances.
Guidelinesfortheintervalare:
• NormalService-yearly
• SevereService-monthlytoquarterly
• SpecialService-asrecommendedbyaqualifiedperson

Writtenrecordsofthemostrecentperiodicinspectionshallbemaintained,andshallincludetheconditionofthesling.
2. Proper Use Of Load-Bearing Devices
Wheneveranyload-bearingdeviceisused,thefollowingpracticesshallbeobserved.
• Load-bearingdevicesthataredamagedordefectiveshallnotbeused.
• Slingsshallnotbeshortenedwithknotsorboltsorothermakeshiftdevices.
• Slinglegsshallnotbekinked.
• Load-bearingdevicesshallnotbeloadedinexcessoftheirratedcapacities.
• Slingsshallbesecurelyattachedtotheirload.
• Load-bearingdevicesshallbeprotectedfromsnagging,andshallnotbefurtherobstructedbyanyobject.
• Suspendedloadsshallbekeptclearofallobstruction.
• Allemployeesshallbekeptclearofloadsabouttobeliftedandofsuspendedloads.
• Handsorfingersshallnotbeplacedbetweentheslinganditsloadwhiletheslingisbeingtightenedaroundtheload.
• Shockloadingisprohibited.
• Donotstanddirectlyunderaloadduringlifting.
3. Storage Of Load-Bearing Devices
Properstorageofout-of-serviceloadbearingdevicesisimportanttoensurefullintegrityofthedeviceonceitisreturnedtoservice.
Farr®recommendsobservingthefollowingpractices:
• Wipeoffallexcessgrease.Useasolvent-basedcleaneronragstowipeallexternalsurfacestoremoveresidualgreaseorhydraulic
fluid.Oncetheoutsidesurfaceshavebeende-greased,wipeallexternalsurfaceswithcleanwatertoremoveresidualsolvent.
• McCoyrecommendsthatananti-corrosiveagentsuchasTectyl®506beappliedtoallexternalsurfaces.Refertomanufacturer
datasheetsforproperapplicationandsafetyinformation.Allowtheanti-corrosivecoatingampletimetodry-refertomanufacturer
datasheetsfordryingtimesatroomtemperature.
• Storeinaclean,drylocation.Whenreturningtoservice,notethatafullinspectionofthedevicemustbeperformed.
UnitsdesignedandmanufacturedinaccordancewithEN12079andDNV2.7-1shouldbetestedandexaminedinaccordancewith
thefollowingscheduleofexaminationandtest.Theuseroftheload-bearingdeviceshallplaceapermanentplacardorplateupon
whichthetypeanddateofthelasttestshallberecorded.Toavoidconfusion,theplateshallnotcarrythedateofthenexttestor
examination,onlythemostrecent.
