Kwiminyaka embalwa edlulileyo ndeva ukuba ingcali yayifuna ukulungiselela umgangatho wemveliso "kwimilinganiselo ye-crane eguquguqukayo", kodwa ngenxa yesizathu esithile ayizange ifakwe.Ngapha koko, ngokusetyenziswa kwesikali se-crane siya kubekwa ngokulula njengesikali esingeyonyani, zininzi iingxaki ezisebenzayo ezingenakuchazwa ngokucacileyo.
A dynamicisikali secranekufuneka ibe sisikali se-crane esinobunzima ngelixa umthwalo uphakamisa kwaye uhamba ngexesha elifanayo ngexesha lokunyusa.Kunzima ukwahlula phakathi kobunzima obuguquguqukayo kunye nobunzima obumileyo ukuba zichazwe nje ngolo hlobo.Kuba “ubunzima obuguquguqukayo” buthetha: umthwalo olinganiswayo kunye nomthwali wesikali kukho intshukumo ehambelanayo, ngelixa isikali secrane sokulinganisa phakathi kwezi zimbini akukho ntshukumo ihambelanayo, kuphela kwizihlandlo ezininzi zokusetyenziswa kwesikali secrane, ngenxa yezixhobo ezijingayo zecrane. eyakho yoqobo.Kuba into eza kulinganiswa ayifane iphumle ixeshana elifutshane, nokuba ixabiso lifundiwe, lisahluke kancinane kwixabiso ekuphumleni.
Izikali ze-Crane ziquka izikali ze-hook, i-crane-type crane scales, i-gantry (ibhulorho) izikali ze-crane.Kwaye izikali zohlobo lwecrane zilingana nobunzima bohlobo lwetroli, uhlobo lokukala intambo yentambo yocingo, uhlobo olusisigxina lwepulley enobunzima njalo njalo.I-Hook intloko ye-crane isikali yiseli yomthwalo efakwe ngokuthe ngqo kwi-hook ye-hook yesixhobo sokuphakamisa, le fomu yesakhiwo somlinganiselo we-crane, uninzi lwendibaniselwano yeentlobo zeeseli zomthwalo.I-Gantry (ibhulorho) izikali ze-crane, ezininzi zazo ziyi-reel ye-reel yocingo.
Xa sijonga imveliso yesikali esifana nesikali se-crane sodwa, sinokuchazwa ngokupheleleyo “njengesikali esingeyonto ezenzekelayo”.Nangona kunjalo, ukuba sijonga yonke inkqubo yokuphakamisa, nokuba yi-crane yebhulorho yaselunxwemeni okanye i-gantry system kwi-harbor, okanye inkqubo ye-crane ephezulu kwishishini okanye kwishishini lemigodi, zonke azinakwahlulwa kuqhagamshelo lwentambo yocingo olude, kwaye bonke bajonga izinto ezilinganisiweyo ngexesha lokunyuswa kunye nokuhamba kwexabiso lenkqubo yobunzima.Kungenxa yale ndlela yokulinganisa kunye nentambo yocingo ukuba oku kudala iingxaki ezimbini zokusetyenziswa kwezikali zecrane:
(1) Kwinkqubo yokuphakamisa, phantsi kwesenzo sesixhobo sokuphakamisa amandla kunye nobunzima bempahla, intambo yocingo exhoma isikali se-crane ngokuqinisekileyo iya kuzolula kunye nokucutheka kwentshukumo, kwaye ngamanye amaxesha izixhobo zokunyusa ezimisa isikali se-crane nazo. ukungcangcazela.Kukule mpembelelo ye-elastic, isikali se-crane asikwazi ukufikelela kwisiphumo sexabiso lokulinganisa ngexesha elifanelekileyo.
(2) Ngokubanzi, isikali se-crane sisetyenziswa ngaphandle, siya kuchaphazeleka kokusingqongileyo, ngakumbi isikali se-crane esisetyenziswe kwi-terminal ye-port, ngomoya uya kuvelisa i-oscillation yesikali se-crane iya kuba ngakumbi ukukhuthaza ukungcangcazela kocingo. intambo, kodwa ichaphazela nefuthe lokungabi ngexesha lokufumana iziphumo zokulinganisa izinto.
