Ifom ye-precast girder formwork ineenzuzo zokuchaneka okuphezulu, isakhiwo esilula, i-retractile, i-demoulding elula kunye nokusebenza okulula. Inokunyuswa okanye irhuqelwe kwindawo yokuphosa ngokudibeneyo, kwaye idilizwe ngokudibeneyo okanye iqhekeza emva kokuba ikhonkrithi iphumelele amandla, emva koko ikhuphe ukungunda kwangaphakathi kwi-girder. Kuluncedo ukufakela kunye nokulungiswa kweempazamo, ukuqina kwabasebenzi abaphantsi, kunye nokusebenza okuphezulu.
