A i-portal boom crane, eyaziwa ngokuba yi-portal crane okanye i-gantry crane, luhlobo lwe-crane oluqulathe indlela yokuphakamisa efakwe kwisakhiwo esijikeleze indawo yokusebenza. Esi sakhiwo sidla ngokuba nemilenze emibini ethe nkqo exhasa umqadi othe tye (i-boom) apho indlela yokuphakamisa ixhonywe khona. Olu yilo luvumela i-crane ukuba ihambise imithwalo ngokuthe tye nangokuthe nkqo ngaphakathi kwendawo echaziweyo, nto leyo eyenza ukuba ifaneleke kwizicelo ezahlukeneyo, njengakwiindawo zokuthumela impahla, kwiindawo zokugcina impahla, nakwizakhiwo zokwenza izinto.
Iimpawu eziphambili zee-portal boom cranes ziquka:
Ukuhambahamba:Iikhreyini ezininzi zesango zenzelwe ukuhamba ngeendlela, nto leyo evumela ukuba zigubungele iindawo ezinkulu kwaye ziphathe izinto ngokufanelekileyo.
Umthamo woMthwalo:Ziyakwazi ukuthwala imithwalo enzima, nto leyo ezenza zifaneleke ukuphakamisa nokuthutha izinto ezinkulu, ezifana nezikhongozeli zokuthutha okanye oomatshini abanzima.
Ukuguquguquka:Iikhreyini zePortal zingasetyenziswa kumashishini ahlukeneyo, kuquka ukwakha, ukuthunyelwa kwempahla, kunye nokuvelisa, kwimisebenzi efana nokulayisha nokukhupha izinto, ukuhlanganisa, kunye nokulungisa.
Uzinzo:Uyilo lwe-crane lubonelela ngozinzo, oluvumela ukuba ikwazi ukuphakamisa imithwalo enzima ngaphandle kokujika.
