Kwimveliso, ulwakhiwo, kunye nothutho, iikhreyini ezithwala imithwalo enzima zibalulekile ekuphatheni imithwalo enzima ngendlela ekhuselekileyo nefanelekileyo. Ezi khreyini zisebenza ngoomatshini zilungelelanisa imisebenzi kwiindawo ezahlukeneyo zoshishino.
Zithini iiKranes eziPhezulu?
Iikhreyini eziphezu komhlaba (okanye iibhulorho) zizixhobo zokuphakamisa kwiindlela eziphakamileyo, eziquka izakhiwo ezifana neefektri kunye neendawo zokugcina impahla. Isakhiwo sebhulorho sihamba kwiindlela ezihamba ngaxeshanye, kunye ne-hoist kunye netroli yokuhamba komthwalo othe tye. Ngokungafaniyo neekhreyini ezihambayo, zizinzile kwindawo ethile, nto leyo evumela ukuthuthwa kwezinto ezinzima rhoqo, okulawulwayo.
Zisebenza ngombane, zibonelela ngolawulo oluchanekileyo lokuphakamisa, ukwehlisa, kunye nokuhamba—zilungele imithwalo ebuthathaka okanye emikhulu, zinciphisa umonakalo kwaye ziphucula ukhuseleko.
Iintlobo zeeKreni eziPhezulu
Iikhrayini ze-Overhead ze-Girder enye
Ngomqadi omnye oxhasayo, ezi zilula, zisebenza kakuhle, zithwala iitoni ezili-1–20. Zifanelekile kwiindawo ezincinci ukuya kweziphakathi ezinesithuba esincinci, nto leyo enceda kakhulu ekusetyenzisweni kwendawo ephezu komhlaba.
IiKreni eziPhezulu zeGirder ezimbini
Zinee-girders ezimbini ezihambelanayo, zithwala iitoni ezimalunga ne-5–500+, zibonelela ngozinzo kumsebenzi onzima kwimizi-mveliso yentsimbi, yokwakha iinqanawa, kunye neemoto. Zingalungiselelwa ngeentlobo ezahlukeneyo zokuphakamisa.
Ukusetyenziswa kweeKreni eziPhezulu
Ukuvelisa
Hambisa izinto eziluhlaza, izinto ezisetyenzisiweyo, kunye neemveliso ezigqityiweyo ngokweemigca zemveliso. Kwizityalo eziziimoto, ziphakamisa iindawo zeenjini kunye neefreyimu; kwimizi-mveliso yentsimbi, ziphatha ii-ingots ezishushu kakhulu, nto leyo ephucula ukusebenza kakuhle komsebenzi.
Indawo yokugcina impahla kunye noLawulo
Beka/fumana iipalethi ezinzima kunye nezikhongozeli, uphucule indawo yokugcina izinto ngokuthe nkqo. Khawulezisa ukulayisha/ukukhulula izinto kwiindawo zokuthutha, uqinisekise ukuba zithunyelwa ngexesha elifanelekileyo.
Ulwakhiwo
Iikhrayini ze-gantry ziphakamisa imiqadi yentsimbi, iiphaneli zekhonkrithi, kunye noomatshini, nto leyo evumela ukuba izakhiwo, iibhulorho kunye neziseko zophuhliso zibe kwindawo ephakamileyo.
Imigodi kunye neeShishini eziNzima
Phatha izixhobo kunye ne-ore kwiindawo zemigodi ezinzima, unyamezele uthuli kunye namaqondo obushushu aphezulu. Kwiindawo zokwenziwa kwezinto, hambisa isinyithi esinyibilikisiweyo ngokukhuselekileyo.
Ulawulo lweNkunkuma
Susa iibhini zenkunkuma, hlela izinto, kwaye ulayishe izinto ezinokuphinda zisetyenziswe, ulungelelanise ukucutshungulwa kwazo ukuze zihlale ixesha elide.
Izinto ezibalulekileyo xa ukhetha i-Overhead Crane
Amandla okuphakamisa
Khetha ikreyini edlula umthwalo wakho ophezulu ukuze uphephe ukusilela kunye neengozi. Vavanya imithwalo eqhelekileyo kunye neemfuno zexesha elizayo ukuze ulungele ixesha elide.
Isithuba kunye nokugubungela
Qinisekisa ukuba ububanzi bekreyini buhambelana nobukhulu besakhiwo, bufikelela kuzo zonke iindawo. Izakhiwo ezinkulu ziyaxhamla kwiikreyini ze-gantry eziphindwe kabini okanye iikreyini ze-gantry ezinde.
Isantya kunye noLawulo
Imisebenzi ifuna isantya esahlukileyo: ukuchaneka okucothayo kwizinto ezibuthathaka, intshukumo ekhawulezayo kwimigca ephezulu. Iikhreyini zanamhlanje zibonelela ngolawulo lwesantya esiguquguqukayo.
Iimpawu zoKhuseleko
Beka phambili ukhuseleko lokugqithisela izinto, ukumisa izinto ngexesha likaxakeka, iiswitshi zokunciphisa, kunye neenkqubo zokulwa nokungqubana. Zidibanise nolondolozo oluqhelekileyo ukuze usebenze ngokukhuselekileyo.
Iimeko zeNdalo
Ukusetyenziswa ngaphakathi kungadinga iikhreyini eziqhelekileyo; iindawo zangaphandle/ezinzima zifuna ukufakelwa izinto ezikhuselayo kunye nezinto ezimelana nemozulu.
Iingcebiso Zokulungisa IiKreyini Ezingaphezulu
Ukugcinwa kakuhle kuqinisekisa ukuhlala ixesha elide, ukhuseleko, kunye nokuthembeka, kuthintela ukonakala kunye neendleko eziphezulu zokulungisa.
Uhlolo lwemihla ngemihla
Jonga umonakalo (imifantu, iindawo ezikhululekileyo) kwibhulorho, kwindawo yokukhwelisa, nakwindlela yokubaleka. Hlola iintambo zentambo ukuba azigugi, iihoko azinaziphene, kunye neendlela zokulawula ukuba zisebenza kakuhle na. Yeka ukuyisebenzisa ukuba kuvela iingxaki.
Uhlolo oluQhelekileyo loBugcisa
Ukuhlolwa kobuchwephesha kwekota/kwesiqingatha sonyaka/konyaka kuchaphazela ukuguguleka koomatshini, ukusebenza kwenkqubo yombane, kunye nokusebenza kwezixhobo zokhuseleko. Iingcali zibona imiba efihlakeleyo.
Ukuthambisa
Landela izikhokelo zomenzi ukuze uthambise iigiya, amavili, kunye neendawo ezijikelezayo, unciphise ukungqubana. Coca i-lubricant engaphezulu ukuze uphephe ukuqokelelana kwenkunkuma.
Ukucoca
Coca imiphezulu rhoqo ukuze uthintele ukuqokelelwa kokungcola, nto leyo enceda ekufumaneni umonakalo ngexesha lokuhlolwa.
Ukhathalelo lwentambo kunye netyathanga
Jonga iintambo ukuba azigugi/zitshatyalalisiwe na kwaye amatyathanga azoluliwe; tshintsha njengoko kufuneka. Qinisekisa ukuba uqhagamshelo oluqinileyo kwiihoko.
Ukugcinwa kwenkqubo yombane
Gcina izinto zomile/zicocekile ukuze zinganxibi iibhulukhwe ezimfutshane. Hlola iintambo kunye neenjini ukuze ubone ukuba azinamonakalo okanye umsebenzi ongaqhelekanga.
Ukugcina iiRekhodi
Ukulandelela uhlolo, ukulungiswa, kunye nokutshintshwa kwezixhobo ukuze kujongwe imbali, kuchongwe iipateni, kwaye kulandelwe imigangatho yokhuseleko.
