1.3 CHECKS BEFORE USE

 Thesechecksshouldbecarriedoutduringinstallationandonafrequentandregularbasisthereafter.Ifthehoistisuseddailythenitis 

 recommendedthattheyarecarriedoutdailyasthecheckstakeonlyminutestocompleteandnotonlyhelpavoidrepairbillsbutsignicantly 

 reducethepossibilityofanaccidentordangerousoccurrence.Thoroughlyexaminetheequipmentpriortoinstallationtoensurethatno 

 damagehasoccurredduringtransit.HoistsandtrolleysshouldnotbealteredinanywaywithoutcontactingRedRoosterforclearance,asthis

 maya󰀨ectthecerticationoftheunit.

AIR SUPPLY CHECKS:

 ▪ Inletpressure:5to6bar(therewillbepressurelossesacrosstheairsetandonlonghoses)Thesupplypressureshouldnot 

  exceed7barasthismaya󰀨ecttheloadlimiter.

 ▪ Airow:Checkairowrequirementandminimumhosediameteralsocheckthatsmallborettingsarenotstranglingtheairow.

 ▪ Keepthelubricatortoppedupwithalightturbineoil(ISOVG3256).

 ▪ Theltershouldbecheckedregularlyandmanualunitsdrainedofwaterasrequired.

 ▪ THE AIR HOSE SHOULD BE SUPPORTED SO THAT THE WEIGHT OF HOSE IS NOT HANGING FROM THE AIR SET AND

`FITTINGS. THE AIR SET IS NOT DESIGNED TO SUPPORT THE WEIGHT OF THE HOSE. SEE PAGES 7 AND 12 IF A HOSE

SUPPORT BRACKET AND MANIFOLD IS FITTED TO THE HOIST.

 ▪ Theairsupplyshouldbecleanandrelativelydry.Wherethecompressorproducesalotofwateractionshouldbetakentoremove 

  theexcesswater.

 ▪ Checkairconnectionsizeandtypearecompatible.

 ▪ Checksecurityofairhoseconnection.

AIR SUPPLY CONNECTION:

 Everyinstallationisdi󰀨erent,sothecorrectmethodofsupportingtheairhoseshouldbereviewedwhileinstallingthehoist.Thisneedsto 

 takeintoaccounttheweightandsizeofthehose,obstructionsbothatdeckandhoistlevel,connections,operatingconditionsandanylikely 

movement of the hoist and air hose.

 Thettingsandlterlubricatorarenotdesignedtotaketheweightofthehose.

 Iftheairsupplyhoselengthisover10metresthehoseIDshouldbeincreasedtothenextsize.

AIR SUPPLY:

 Vanetypeairmotorsaredesignedtofunctionusingclean,dry,lubricatedair.Theinstallationofan‘inline’airserviceunitalthoughessential 

cannot in itself compensate for serious contamination in the air supply. When operating the compressor in moist (humid) or dusty atmospheres

 seektheadviceofyourcompressorsupplierwithregardtothettingofadryerandlter.

AIR PRESSURE:

 Thehoistisdesignedtooperatebestinthepressurerangeof5to6bar(72to90p.s.i).Thespeedsquotedonthemanufacturer’sliterature 

 areobtainableonlyat6bar(90p.s.i)inletpressure.Thehoistwilloperateatmuchreducedspeedatpressuresbelowthisgure.

AIR FLOW:

 Refertothehoistdatasheet,toselectthehosediameterwhichensuresadequateairow.Failuretoprovideadequateairowwillresultina 

 pressuredropinthesupplylineandcausethehoisttostallandthebraketoapplyuntilthepressureincreases.Inaddition,thebrakewillnot 

 releasecleanlyandwilloverheat.(Althoughnotinitselfahazard[thebrakefailssafe]itmayprovefrustratingtotheoperatorandahazard 

 mayariseasaconsequence.)

HOSE SUPPORT BRACKET:

 Whereahosesupportbracketandmanifoldhavebeenttedtothehoisttotaketheweightofanairsupplyhose,severalchecksmustbedone.

 ▪ Checkthehosehangsfreelyanddoesnotinterferewiththehoistchain.

 ▪ Checkthehoseisclearoftheloadtobelifted.

 ▪ Checkthependanthoseisnotobstructedbytheairsupplyhose.

 ▪ Checktheairhoseissupportedbythehoseclamp/former/festoonsystem.

 ▪ DOuseexclusivelycorrectlyratedandcertiedpneumatichosesandttingsintheairsupplyline.

 ▪ DOsupporttheairlineuptothehoist,asthettingandlter/lubricatorarenotdesignedtotakealoadandmaynotsupportthe 

weight of the hose.

 ▪ DOmaintaintheinternaldiameter(asperthetablethroughoutthesupplylength)orreducefromthelargerdiametertothe 

smaller diameter in the direction of the hoist.

 ▪ DON’Tusehydraulicttings.Theseoftenhaveareducedoricesizeresultinginadownlinedropinairpressure.

 ▪ DON’Tincreasefromsmallertolargerdiameterorinsertalengthofsmallerdiameterhoseinthesupplylineasthiswillresultin 

 reducedowandpressure.

 ▪ DON’Tcreatelowpointsintheairsupplylinewherewatermaybetrapped(orifunavoidableinstalladraintap).

 ▪ DON’Trelyonpneumaticttingstosupportairlines;theyarenotdesignedforthispurpose.

 ▪ DON’Tshortenthependantbyformingalooporacoil.Thiswillpreventthestrainerwirefromsupportingthependantandwill 

 causethehosestobecomedetachedorkinked.

 ▪ Wherelongcontrolsarefittedtoahoisttheyarecolourcodedforre-connectiononsite.

 ▪ Whenliftingintopositioneitherusetheliftingpointsonthehoistorhoistandtrolley,ifthehoistdoesnothaveliftingpointsfitted 

  securelyfitslingstothebodyofthehoistorusethetophookifpossible.Donotliftbythecontrols,valves,ortheairset.

MOUNTING THE HOIST

 TheairhoistisdesignedasaLIFTINGMACHINEandassuchisdesignedexclusivelyfortheliftingloadsvertically.Nonverticalliftingwill 

result in premature wear of the chain and chain guide and may result in damage to the limit arms or a failure of the limit arms to operate.

 ▪ Sitethehoistimmediatelyabovetheloadwhichistobelifted.

 ▪ Ensurethatthepointfromwhichthehoistissuspendedhasbeendesignedandtestedtoatleastthesamesafeworkingloadas 

the hoist itself.

 ▪ Ensurethatthesuspensionpointorshackletssnuglyintothebowlofthehoisttophookandthatthesafetycatchclosesto

prevent escape.

 ▪ UseonlycertiedliftinggearwithaSWLinexcessoftheloadtobeliftedtoconnecttotheloaditself.

 ▪ Ensurethattheliftinggeartssnuglyintothebowlofthehoistbottomhookandthatthesafetycatchclosestopreventescape.

 ▪ Ensurethatthecontrollength(pendantorcords)isadequatetoallowtheoperatortostandawayfromtheload,inasafeand 

secure position with the cords or pendant at waist height.

CLOSE HEADROOM WORKING

The lower hook of the TMH hoist includes a swivel arrangement. This allows the load to turn without twisting the chain. However, when

 repeatedlyhandlingloadswiththebottomhookclosetothehoist,especiallywhenrotationoftheloadisprevented,thereistendencyforthe 

 chaintoattempttoentertheguideatanangle.Thisisparticularlypronouncedontwofallunits.Ifthisproblemisnoticedwhendoingatriallift,

 ahighqualityballbearingswivelshouldbemountedbelowthebottomhookofthehoist.

CHAIN COLLECTORS

 Ifthehoisthasbeensuppliedwithachainbucket,andthechainhasbeenstoredwithinitduringshipment,removeallthechainfromthecollector

 byhand,andremoveanyknotsortwists.

 Inallcasescarefullyfeedthechainovertheloadwheelallowingittollthecollectorwithoutanyinterferenceasitemergesfromthewheel. 

 Thiswaythecollectorwillllnormally.Ifthechainwithinthecollectorisdisturbedgreatcaremustbetakenthenexttimethatthechainisfed 
