Isikrini sokuvikela siyisistimu yokuphepha ekhethekile eyenzelwe ukwakhiwa kwesakhiwo esiphakeme. Sakhiwe ngojantshi kanye nohlelo lokuphakamisa amanzi, sinamandla okukhuphuka ngokuzimela aqeda isidingo sosizo lwe-crane ngesikhathi sokuphakama. Lolu hlelo luhlanganisa ngokuphelele indawo yonke yokuthulula futhi lungamboza izitezi ezintathu ngesikhathi esisodwa, okunciphisa ngempumelelo izingozi zokuwa eziphakeme futhi kuqinisekise ukuphepha kwendawo yokwakha iyonke.
Ngaphezu kwalokho, ingalungiswa ngamapulatifomu okukhipha imithwalo, okwenza kube lula ukuthuthwa kwefomu nezinye izinto eziya phansi phezulu ngaphandle kokudinga ukuhlukaniswa kusengaphambili. Ngemva kokuthululwa kwe-slab, i-formwork kanye ne-scaffolding kungathuthelwa epulatifomu yokukhipha imithwalo bese kuphakanyiswa ezingeni elilandelayo nge-tower crane ukuze kwakhiwe okulandelayo—le nqubo inciphisa kakhulu izindleko zabasebenzi kanye nezinto zokwakha ngenkathi isheshisa inqubekela phambili yokwakha iyonke.
Isebenza ngohlelo olukhethekile lwe-hydraulic, isikrini sokuvikela sifinyelela ekukhuphukeni ngokwaso ngaphandle kokuthembela kuma-crane. Ipulatifomu yokulayisha ehlanganisiwe yenza kube lula ukudluliselwa kwezinto ngokuvumela ukuthuthwa kwefomu kanye nezinto ezihlobene nazo ezitezi eziphezulu okungadilizwanga.
Njengesixazululo sokuphepha esithuthukisiwe nesisezingeni eliphezulu, isikrini sokuvikela sihambisana nezidingo zokuphepha kanye nokwakhiwa okujwayelekile, ngakho-ke samukelwe kabanzi kumaphrojekthi okwakha imibhoshongo emide. Ngaphezu kwalokho, ipuleti lezikhali langaphandle lesikrini sokuvikela lingasebenza njengendawo enhle kakhulu yokukhangisa yokukhangisa komkhiqizo womkontileka wokwakha.
