Isikrini sokukhusela yinkqubo yokhuseleko ekwakhiweni kwezakhiwo eziphakamileyo. Le nkqubo inee-rails kunye nenkqubo yokuphakamisa i-hydraulic kwaye iyakwazi ukunyuka yodwa ngaphandle kwe-crane. Isikrini sokukhusela sinendawo yonke yokugalela evaliweyo, igubungela imigangatho emithathu ngaxeshanye, enokuthi iphephe iingozi zokuwa komoya ophezulu kwaye iqinisekise ukhuseleko lwendawo yokwakha. Le nkqubo inokuxhotyiswa ngamaqonga okukhupha imithwalo. Iqonga lokukhupha imithwalo lilungele ukuhambisa iifomwork kunye nezinye izinto ukuya kumgangatho ophezulu ngaphandle kokuziqhekeza. Emva kokuthulula i-slab, ifomwork kunye ne-scaffolding zinokuthuthwa ziye kwiqonga lokukhupha imithwalo, kwaye emva koko ziphakanyiswe yi-tower crane ukuya kumgangatho ophezulu ukuze kusebenze inyathelo elilandelayo, ukuze igcine kakhulu abasebenzi kunye nezixhobo zezinto kwaye iphucule isantya sokwakha.
Le nkqubo inenkqubo ye-hydraulic njengesixhobo sayo samandla, ngoko ke inokunyuka yodwa. Ii-cranes azifuneki ngexesha lokunyuka. Iqonga lokukhulula izinto lilungele ukuhambisa iifomwork nezinye izinto ukuya kumgangatho ophezulu ngaphandle kokuziqhaqha.
Isikrini sokukhusela sisixhobo esiphucukileyo nesisemgangathweni esihambelana neemfuno zokhuseleko nempucuko kwindawo leyo, kwaye ngokwenene sisetyenziswe kakhulu ekwakheni iinqaba eziphakamileyo.
Ngaphezu koko, ipleyiti yezixhobo zokuzikhusela yangaphandle yibhodi yentengiso elungileyo yokwazisa umntu oza kuyisebenzisa.
