Master Links uye Master Link Assemblies zvinhu zvakakosha zvekugadziramakumbo akawanda ekusimudza slings.Kunyange zvazvo ichinyanya kugadzirwa secheni chipfuramabwe chinoshandiswa kune ese marudzi ezvipfuramabwe zvinosanganisira waya tambo slings uye webbing slings.
Kusarudza kwakaringana uye kunoenderana master links hakuna kutwasuka zvakadaro. Kune akasiyana akanaka emhando dzechetani dzezvipfuramabwe dzatingade kubatanidza nepo zviyero nemaitiro zvichisiyana zvakanaka - saka zvinobatsira kukurukura dzimwe nyaya uye zvinongedzo.
Chii chinonzi Master Link?
Master Links uye Master Link Assemblies anozivikanwawo nemamwe mazita anosanganisira oblong links, zvindori zvemusoro, multi-master link assemblies etc. Ndiyo imwe yemhando dzekare dzekare dzekusimudza tackle uye dzinogara pamusoro pemakumbo akawanda ekusimudza slings.
Multiple-leg lifting slings inogona kuve yakakosha pakugovera masimba ekusimudza uye kuwana kugadzikana uye kutonga kwemubhadharo watinoda kusimudza. Dambudziko guru nderekutizvipfuramabweuye zvikamu zvechipfuramabwe zvinonyanya kugadzirirwa nzvimbo imwechete yekubatanidza kutakura mutoro. Kana isu tiine makumbo maviri, matatu kana mana kune yedu chipfuramabwe, saka rimwe nerimwe remakumbo iwayo rinoda chimwe chinhu chinoachinjisa kuti aenderane nenzvimbo yekunamatira (senge crane hook) kana imwe yekukodzera inogamuchira gumbo rimwe chete panguva.

Nzira iyo master links inosvika pakubatana yakakosha.
Kune makumbo maviri sling izvi zviri nyore nyore, Master Link yakatemerwa kusvika kune maviri echipfuramabwe akabatana pazasi kwayo:
Kune ina yegumbo sling, izvi zvakare zviri nyore nyore. Kubatanidza makumbo mana akaremerwa kusvika kumagumo emaster link kunorambidzwa, asi tichishandisa Master Link Assembly (Multi-Master Link) tinogona kuwanza maviri maviri kuti tiwane makumbo mana:
Makumbo matatu ari tricker. Mamwe magwaro ekare anogona kuratidza makumbo matatu muchinhu chimwe chete, zvisinei, izvi zvave kurambidzwa. Nzira yakakodzera ndeyokushandisa nzira imwechete segadziriro yemakumbo mana uye kushandisa sling imwe chete pane imwe yepakati.

Working Load Limit
Tinogona kutarisa pamifananidzo iri pamusoro tofunga kuti hupenyu huri nyore - asi kwete nekukurumidza!
Ndeipi Working Load Limit (WLL) yatinofanira kutsvaga?
Zvichida iyi ndiyo yekutanga yematambudziko mazhinji atichasangana nawo.
Nechipfuramabwe chemakumbo akawanda tinofanira kuona kuti makumbo ose echipfuramabwe uye Master Link ane WLL yakakwana yebasa racho. Tinogona kusarudza zvikamu mune imwe yenzira mbiri - tinogona kusarudza makumbo atinoda kutanga, tozosarudza Master Link kuti ienderane - kana isu tinogona kusarudza Master Link kutanga, tozowana makumbo echipfuramabwe ane akaringana akayerwa masimba.
Kuti tiite karukuro iyi tinofanira kutanga taziva kona yechipfuramabwe.
MuAustralia iyi ichava kona inosanganisirwa pakati pemakumbo echipfuramabwe, uye iyo yakawanda WLL yatinogona kugovera ichaverengerwa pa60 madhigirii.
Australian Standard Sling Angle yekuverenga iyo yakanyanya WLL.
Kuve ne 60 ° rating inowanikwa kwatiri inogona kubatsira zvakanyanya nekuti inobatsira kukwidziridza kugona kugona uye kubatsira kwezvipfuramabwe zvedu.
Pane kubata zvakadaro - uye ndiyo yakajairika yeEuropean standard (EN standard) .

Zvakare, mitemo yeEurope inosiyana. Zvavanobvumira ndezvekuyera makumbo mana emakumbo pamakumbo matatu. Chokwadi chipfuramabwe chemakumbo mana hachigone kuzvitsigira pamakumbo matatu - inzira inovakirwa panhamba chete.
Ichi ndicho chimwe chezvinhu izvo dzimwe nguva zvinoshanda uye dzimwe nguva hazvishande. Muzviitiko apo mitoro yakaoma uye pane dzimwe nguva apo zvikamu zvechipfuramabwe zvinoswedera pedyo nechimiro chechokwadi chepiramidhi chikamu chemutoro pakati pemakumbo chinogona kuva chisina kunaka uye chipfuramabwe chinofanira kuderedzwa kuti chiverengere makumbo akarembera.
Zvazvinoreva pakusarudzwa kweMaster Link magungano zvakadaro ndezvekuti kana master link WLL ichitorwa sechinhu chimwe chete chakakosha mhiri kwemakungwa - izvi zvinogona kureva kuti ma link haana kusimba zvakakwana.
A European Master Link inoshanda seizvi:
Izvi zvinoshanda neEN sling zviyero, asi hazvisi zvechisikigo zvinoenderana neAustralian Standards. Zvakakosha, hazvina kupusa kumushandisi - ndiko kuti, kunze kwekunge sarudzo yechigadzirwa yaitwa nemazvo kuti ienderane nemitemo yeAS3775.
European Standard Master Link Assemblies ingangoda kuderedzwa kuitira kuti epakati malink akasimba zvakakwana.
Kuisa Crane Hook
Vazhinji vashandisi vezvipfuramabwe vanotarisana nenyaya yekuita kuti slings ishande nema crane hooks. Pamwe iyo crane hook idiki zvakanyanya kune yekusimudza tackle - kana yekusimudza tackle idiki zvakanyanya kune crane hoko.
Kuti ugadzirise masterlink kune crane hook, yambiro yakakosha inokurudzirwa pamwe nemisanganiswa inokwana.
Ese makoko ecrane anogadzirwa kuti ave akasimba mukukotama mundege imwe. Kuti vawedzere kushanda kwesimba vanoshandisa chikamu chemuchinjikwa chakadzika kupfuura chakafara, uye chakakora mukati kupfuura kunze.
Kuongorora kukwana kweMasterlink uye hoko.
Kuzarisa
Tinoda kuti malinks edu ave akareba zvakakwana kuti akwane zvinhu zvakaita sezvikorekedzo zvecrane kumusoro kwadzo pamwe nekuisa pazasi - asi sezvatinoona pamusoro, kazhinji dzinofanirwa kunge dzakafara zvakakwana zvakare.
Izvi hazvisi chete zvinodiwa kune crane hook. Icho chinodiwa kune sling leg interfaces.
Kana zvikamu zvekukwirana zvisingagone kugara mune chinongedzo uye kutakura mitoro nenzira kwayo zvinongedzo zvakawandisa. Izvi zvinosimbisa zvikamu nenzira dzisina kujairika uye hazvibvumirwi.
