*Whenusing3hoistsormoreonaplatform,consultSpiderproductsupportat+1(206)394-5319forpropergensetratings.
Theserecommendedgensetratingsaretheminimumrecommendedbasedonintermittentplatformmovement(lessthan10
minutesofcontinuousupwardtravel)andstandardambientconditions.
Usingalargercapacitygeneratorisalwaysacceptable,andisadvisedifanyofthefollowingarepresent:
 • Ambienttemperatureover100°F
 • Relativehumidityover50%
 • Siteelevationabovethan5000feet
 • Cordlengthover250feet,wheretransformerisnotused.
 • Runningthehoistscontinuouslyformorethantenminutes
IMPORTANT:Verifythevoltageoperatingrangeofthehoistbeforepluggingitintothegenerator.Voltagethatistoohighortoo
lowwilldamageahoist,causingworkdelaysandexpensiverepairs.Consultthehoistoperator’smanualbeforeyoustart.Use
abuckorboosttransformertoadjustoutputvoltageofthegeneratortomeetthehoist’sspeciedvoltage.Verifythatthetrans-
formeriswiredforthedesiredbuckorboostfunction.
Key Term What you need to know:
Portable Engine- Anengine-drivengeneratoror‘genset’.Engineconvertsfuelintomechanicalpower;
Generator set generatorconvertsmechanicalpowerintoelectricalpower.
Fuel   Eitherdieseloil,gasoline,naturalgasorpropanevapor.

Voltage Regulator Controlstheoutputvoltageastheloadchanges.Usuallynotadjustableonportableunits.
Frequency (Hz) ThenumberoftimespersecondtheACvoltageandcurrentgofrommaximumtominimum
   andbacktomaximum.

   varyingloads.
!! Increased air temperature, humidity and elevation reduces the engine power output,

Generator Size Recommendations
& Operations Overview
Inverters  AnelectronicdevicethatconvertsDCelectricalpowerintoACelectricalpower.
   InvertergeneratorsuseaDCgeneratorconnectedtoaninvertercreatingACpower.
   Typicallyquieter,weighless,uselessfuel.
   Limitedpoweroutputandeasilydamagedbysuddenloadsurges.
3-Phase Power Electricalpowerprovidedbythegridin3phases,orseparatelines.Usedforequipmentwithhigh
startup loads
Single-Phase PowerUsedformosttoolsanddevices.Oneofthethreecircuitscomingfromthegrid.
Startup/Run Factor Powerrequiredwhenanelectricalmotorisstartedwithaloadalreadyappliedtoit
   (suchasahoistsupportingaplatform).

TROUBLESHOOTING POOR HOIST PERFORMANCE AND DAMAGE DUE TO:
.
Low Engine Speed/ Outputfrequencymeasuredwithamulti-meteratthepoweroutletorendofthepowercordmust
Output Frequency measurebetween58and62Hz.Ifyougetadifferentreading,consulttheoperator’smanualor
   contactthegenset’sauthorizedserviceprovider
   Checktoseeifthegensetissetin“energysaver”mode.Thismodeidlestheengineuntilaloadis
   appliedtoit.Thehighstartuploadsofahoistmotorcandamagethegensetwheninthismode,
   andalsothehoistmotor.Keepthegensetinfullrunmode.
Incorrect Voltage Ifoutputvoltageatthegensetgaugepanelormeasuredwithamulti-meteratthegensetoutletis
   lessthantheratedhoistvoltagewithnoload,donotusethegensettopowerthehoist.Checkthe
   gensetoperator’smanualforhowtoadjusttheoutputvoltageorcontactthegen-set’sauthorized
   serviceprovider.
   Ifthevoltageattheoppositeendofthecordislessthantheratedhoistvoltageornovoltageis
   measured,checkforincorrectsocket/plugalignmentinthecord,plugandsocket.
   Orientationofconnectorpinsandsockets(xtox,ytoy,etc)oneachwiremustbecorrectorthevoltage
   and/orphasewillbeincorrect
Low Fuel Level Lowfuelsupplyaffectsthegen-setspeed,causingvoltageandpowersurgesthatcandamagethehoist.
   Consultthegensetoperator’smanualsforfuelconsumptionratesandmakesureenoughfuelis
   availablefortheoperatingshift.
   Consultthegensetoperator’smanualsafetyconsiderationsduringrefuelingandonre-startingafter
refueling
Intake, Exhaust and Restrictingthegensetairintake,exhaustorcoolingsystemswillresultinlowpoweroutput,overheating
Cooling System anddamage.Thegensetmustbeinanopenspacewithplentyofroomaroundittodrawinairandlet
Blockage exhaustgasesleavethearea.
AlwaysfollowOperator’sManualsinstructions,dailyoperationstests,andtroubleshootingsteps.
