Ukubaluleka kunye nenjongo yeeKreyini zeZibuko kuShishino loThutho
Iikhreyini zezibuko, ezaziwa ngokuba ziikhreyini zeekhonteyina, ziyinxalenye ebalulekileyo kushishino lokuthumela impahla. Zidlala indima ebalulekileyo ekuqinisekiseni ukulayisha nokukhulula impahla kwiinqanawa ngokukhuselekileyo nangokufanelekileyo. Injongo ephambili yeekhreyini zezibuko kukuhambisa impahla ekwikhonteyina ukusuka enqanaweni ukuya edokini, kwaye ngokuchaseneyo. Ezi kreyini zinamandla kwaye zinokuthwala impahla enobunzima beetoni ezininzi.
I-port crane yinxalenye ebalulekileyo kwikhonkco lezothutho, kwaye ishishini lokuthumela lixhomekeke kuyo ukuhambisa malunga ne-90% yeempahla zorhwebo zehlabathi. Ngaphandle kwe-port crane, icandelo lokuthumela ngenqanawa belingenakukwazi ukusebenza ngokufanelekileyo. Ukukwazi kwe-crane ukuphatha imithwalo ngokufanelekileyo yikona okwenza ibe yimpahla exabisekileyo kwishishini lokuthumela ngenqanawa. Ii-port crane zenzelwe ukuphatha izikhongozeli zokuthumela ngenqanawa ezinobukhulu obahlukeneyo, ukusuka kwizikhongozeli ezincinci ezingama-20-foot ukuya kwizikhongozeli ezinkulu ezingama-40-foot.
Isantya nokusebenza kakuhle kwekreyini yezibuko kuncedisa kakhulu ekusebenzeni kakuhle kwesakhiwo sezibuko. Ukukwazi kwekreyini ukuphatha imithwalo ngexesha elifutshane kuthetha ukuba iinqanawa zinokuchitha ixesha elincinci kwizibuko, kunciphisa ukuxinana kwezibuko kwaye kwandise ukuhamba kwemithwalo. Ukongeza, iikreyini zezibuko zinceda ukuphucula ukhuseleko ngokunciphisa iingozi zokwenzakala kubasebenzi kunye nomonakalo kwimithwalo. Zikwabalulekile ngamaxesha eengxaki, njengeentlekele zemvelo kunye nobhubhane, apho amazibuko edlala indima ebalulekileyo ekuqinisekiseni ukuba iimpahla ezibalulekileyo ziyafikelela kwindawo eziya kuyo.
Ukuqukumbela, injongo yekreyini yezibuko kukwenza kube lula ukuhamba kwempahla ukusuka enqanaweni ukuya edokini kube lula kwaye ngendlela echanekileyo. Ezi kreyini zibaluleke kakhulu kushishino lokuthumela impahla kwaye ziqinisekisa ukuhanjiswa kweempahla ngexesha elifanelekileyo kwihlabathi liphela. Ukukwazi kwazo ukuhambisa impahla ngokukhuselekileyo, ngokukhawuleza, nangokufanelekileyo, kuzenza zibe yimfuneko kushishino lokuthumela impahla. Ukubaluleka kwekreyini yezibuko kudlula ngaphaya komsebenzi; zidlala indima ebalulekileyo kuqoqosho lwehlabathi, ukwenza kube lula urhwebo lwamazwe ngamazwe, kunye nokuqinisekisa ukuba iimpahla ezibalulekileyo zifikelela kwindawo eziya kuyo, nto leyo eyenza zibe yinto ebalulekileyo kwihlabathi esiphila kulo namhlanje.
