Eminyakeni embalwa edlule ngezwa ukuthi uchwepheshe wayefuna ukulungisa izinga lomkhiqizo "ezikalini ze-crane ezinamandla", kodwa ngesizathu esithile akuzange kwethulwe.Eqinisweni, ngokusetshenziswa kwesikali se-crane sizobekwa nje njengesikali esingesona esizenzakalelayo, kunezinkinga eziningi ezisebenzayo ezingeke zichazwe ngokucacile.
A ashukumisayoisikali se-cranekufanele kube isikali se-crane esikala ngenkathi umthwalo uphakamisa futhi uhamba ngesikhathi esifanayo phakathi nenqubo yokuphakamisa.Kunzima ukuhlukanisa phakathi kwesisindo esiguquguqukayo kanye nesisindo esimile uma zichazwa nje kanjalo.Ngoba “isisindo esishintshashintshayo” sisho: umthwalo okalwayo kanye nesithwali sesikali kukhona ukunyakaza okuhambisanayo, kuyilapho isikali se-crane sokukala phakathi kwalokhu okubili akukho ukunyakaza okuhlobene, kuphela ezikhathini eziningi zokusebenzisa isikali se-crane, ngenxa yezinto ezilengayo ze-crane. okwangempela.Njengoba into ezokalwa ingavamile ukuphumula isikhathi esifushane, ngisho noma inani lifundwa, lisahluke kancane kunani ekuphumuleni.
Izikali ze-crane zihlanganisa izikali ze-hook, izikali ze-crane zohlobo lwe-crane, izikali ze-crane ze-gantry (ibhuloho).Futhi izikali ze-crane zohlobo lwe-crane cishe zilinganisa uhlobo lwe-trolley, uhlobo lwesisindo se-reel yentambo, uhlobo lwesisindo se-pulley olumisiwe njalonjalo.Isikali se-hook head crane iseli lomthwalo elifakwe ngqo ekhanda lehhuku lemishini yokuphakamisa, leli fomu lesakhiwo lesikali se-crane, iningi lenhlanganisela yezinhlobonhlobo zamaseli omthwalo.I-Gantry (ibhuloho) izikali ze-crane, eziningi zazo eziwuhlobo lwesisindo se-reel yezintambo.
Uma sibheka umkhiqizo wesikali njengesikali se-crane sisodwa, singachazwa ngokuphelele ngokuthi "isikali esingesona esizenzakalelayo".Kodwa-ke, uma sibheka lonke uhlelo lokuphakamisa, kungakhathaliseki ukuthi i-crane yebhuloho lasogwini noma i-gantry system echwebeni, noma isistimu ye-crane ephezulu ebhizinisini lezimboni noma lezimayini, zonke azihlukaniseki kusukela ekuxhumekeni kwezintambo zezintambo ezinde, futhi bonke babheka izinto ezikaliwe ngesikhathi sokuphakamisa nokuhambisa inani lesisindo senqubo.Kungenxa yale ndlela yokukala kanye nentambo yocingo ukuthi lokhu kudala izinkinga ezimbili zokusetshenziswa kwezikali ze-crane:
(1) Enqubweni yokuphakamisa, ngaphansi kwesenzo samandla okuphakamisa okokusebenza kanye namandla adonsela phansi ezimpahla, intambo yocingo emisa isikali se-crane nakanjani izokwelula futhi ifinyeze ukunyakaza, futhi ngezinye izikhathi okokusebenza kokuphakamisa okumisa isikali se-crane nakho ukuthuthumela.Kukulo mphumela wokunwebeka, isikali se-crane asikwazi ukufinyelela umphumela wenani lokukala ngesikhathi esifanele.
(2) Ngokuvamile, isikali se-crane sisetshenziswa ngaphandle, sizothintwa imvelo, ikakhulukazi isikali se-crane esisetshenziswa esikhumulweni sechweba, ngomoya sizokhiqiza ukuzulazula kwesikali se-crane kuyoba ngaphezulu ukukhuthaza ukuthuthumela kocingo. intambo, kodwa futhi kuthinte umthelela wokungabi nesikhathi sokuthola imiphumela yokukala yezinto.
