Isikrini sokuvikela siwuhlelo lokuphepha ekwakhiweni kwezakhiwo eziphakeme. Uhlelo luqukethe ama-rails kanye ne-hydraulic lifting system futhi iyakwazi ukuzikhuphukela ngokwayo ngaphandle kwe-crane. Isikrini sokuvikela sinendawo yonke yokuthela evalekile, evala izitezi ezintathu ngesikhathi esisodwa, okungagwema ngempumelelo izingozi zokuwa komoya okuphezulu futhi kuqinisekise ukuphepha kwendawo yokwakha. Uhlelo lungahlonyiswa ngezinkundla zokuthulula. Isiteji sokuthulula silungele ukuhambisa i-formwork nezinye izinto ezitezi ezingaphezulu ngaphandle kokuhlakazeka.Ngemva kokuthulula i-slab, i-formwork kanye ne-scaffolding ingathuthelwa endaweni yesikhulumi sokuthulula, bese iphakanyiswa nge-tower crane ukuya ezingeni eliphezulu ukuze isinyathelo esilandelayo sisebenze, ngakho-ke. ukuthi isindisa kakhulu abasebenzi kanye nezinsizakusebenza futhi ithuthukise isivinini sokwakha.
Isistimu ine-hydraulic system njengamandla alo, ngakho-ke ingakwazi ukukhuphuka ngokwayo. Ama-cranes awadingeki ngesikhathi sokukhuphuka. Ipulatifomu yokuthulula ilungele ukuhambisa i-formwork nezinye izinto ezitezi ezingaphezulu ngaphandle kokuhlakazeka.
Isikrini sokuvikela siyisistimu ethuthukisiwe, esezingeni eliphezulu evumelana nesidingo sokuphepha nempucuko esizeni, futhi ngempela sisetshenziswe kabanzi ekwakhiweni kombhoshongo osezingeni eliphezulu.
Ngaphezu kwalokho, i-armor plate yangaphandle yesikrini sokuvikela iyibhodi lokukhangisa elihle elizosakazwa ngusonkontileka.
