Thepurposeofthismanualistoprovidethecalibrationtechnicianwiththeprocedures
essentialforthepromotionofpropermachineoperationforitsintendedpurpose.The
importanceofproperusagecannotbeoverstressed.
Thecalibrationtechnicianshouldhaveread,andbefamiliarwith,theinstruction
manualsuppliedwiththesystem.
Allinformationinthismanualshouldbereadandunderstoodbeforeanyattemptis
madetocalibratethemachine.

Sincethemanufacturerhasnodirectcontrolovermachineapplicationandoperation,
conformancewithgoodsafetypracticeinthisareaistheresponsibilityoftheuserand
hisoperatingpersonnel.

Allprocedureshereinarebasedontheuseofthesystemunderproperoperating
conditions,withnodeviationsfromtheoriginaldesign.Alterationand/ormodification
oftheequipmentarestrictlyforbiddenwithoutwrittenapprovalfromRaycoWylie
Systems.

Thei4500RaycoWylieSystemsRatedCapacityIndicator(RCI)istoberegardedonlyas
anaidtotheoperator.Whentheparametersaresetcorrectly,theindicatorwillwarn
thecraneoperatorofanapproachingoverloadconditionthatcouldcausedamageto
equipment,property,and/orinjurytotheoperatororsiteworkersinthevicinityofthe
craneanditsload.Priortothecalibrationbeingcompletedthesystemwillnotprovide
correctwarningsanditisessentialthatothermeansareusedtoestablishsafeuseof
themachine.

Thissystemmustneverbeused,underanycircumstances,asasubstituteforthegood
judgmentofacraneoperatorwhencarryingoutapprovedcrane‐operatingprocedures.
Responsibilityforthesafeoperationofthecranelieswiththecraneoperator.The
indicatorequipmentwillnotnecessarilypreventcranedamageduetooverloadingand
relatedcausesifnotsetproperly.

BeforeoperatingacraneequippedwithaRaycoWyliesystemRCI,theoperatormust
carefullyreadtheinformationinthei4500operatormanualandthecranemanufacturer
operator’smanual.Hemustalsobeawareofallthefederal,stateandlocalsafety
standardandregulationsapplicabletohisjob.Correctfunctioningofthesystem
dependsuponroutinedailyinspection.

Anysuspectedfaultsorapparentdamageshouldbeimmediatelyreportedtothe
responsibleauthoritybeforeusingthecrane.

1INTRODUCTION

Thismanualcontainscalibrationinformationforthei4500system.Whenperforming
calibrationofthei4500system,alwaysobservethesafetyrulesandregulations
applicableinthecountryofoperationtoreducetheriskofpersonalinjuryordamageto
theequipment.Eachsafetyinstructionthroughoutthismanualmustbetakeninto
considerationwhenusingthei4500system.Theinformationcontainedinthismanual
willenablequalifiedpersonneltoproperlyoperateandefficientlyperformcalibration.

1.1Personnelqualificationandscopeofthismanual

Installationofthei4500systemshallbeperformedbyaqualifiedtechnician.
Furthermore,calibrationofthei4500systemmustbeperformedbyaRaycoWylie
trainedtechnician.TheRaycoWylietechnicianwillperformacompleteandstructured
verificationofthewholesystembeforebeginningthesystem’scalibration.
Failuretocalibratethesystemproperlycanresultinoverloadingofthecranerisking
machinebreakageortippingthatcouldresultinseriousinjuryordeath.Alwaysreferto
aRaycoWylietrainedtechniciantocalibrateyoursystem.
