Indima yefasitela lokubuka emnyango wegumbi elihlanzekile ngokuyinhloko ukusiza abantu babone isimo esijwayelekile ngaphakathi komnyango ngaphandle kokuvula umnyango, futhi baqonde ngokushesha ulwazi oluthile oluyisisekelo.Inciphisa isikhathi sokusebenza sabasebenzi futhi ayidingi ukuvula umnyango njalo ukuhlola isimo ngaphakathi.Iwindi lokubuka livame ukuklanywa ngengilazi epholile enezendlalelo ezimbili.I-ejenti yokuvikela umswakama noma ukucubungula okomile okugcwele i-nitrogen kungafakwa efasiteleni lokubuka.Ngemva kwesikhathi eside, endaweni enomswakama ngokuqhathaniswa, ukuhwamuka okubangelwa umswakama kuzobangela ukuba amaconsi amanzi abambelele.Engilazini nhlangothi zombili.
Ngenxa yokuthi wonke umuntu unobuhle obuhlukene, ngaphezu kwemibala eminingi yomnyango ohlanzekile, ukuma kwefasitela lokubuka kungabuye kukhethwe ngokuvumelana nesimo sangempela endaweni.Izimo ezivamile zefasitela lokubuka zingunxande, ziyindilinga, njll. Ukucubungula kwe-radian ye-15-degree emagumbini amane efasitela lokubuka kunezinzuzo eziningi ngaphezu kokubukeka kwayo okuhle.Uma amakhona amane engama-engeli angakwesokudla, kuzonikeza abantu umuzwa obukhali, onembile, kanye nokucophelela.Ngokuphambene, i-arc yenza abantu bazizwe bezinzile, bemnene, bechachambile futhi bengeneka.Ukusetshenziswa kweminyango ehlanzekile ezibhedlela kanye nefasitela lokubuka i-arc enamakona amane kwenza kube lula ukudala indawo ekhululekile nenethezekile yeziguli futhi zizisize zilulame ngokushesha.
Iwindi lokubuka Uma kubhekwa umphumela wangempela wokubhekwa, umphumela wokubheka oqondile wefasitela lokubuka elingunxande mubi kakhulu kunalowo wesikwele nesiyingi, futhi umphumela wangempela wokubhekwa okuvundlile awumuhle njengendilinga nesikwele, kodwa ukuphakama kwabasebenzi akuphakeme.Umthelela wokubuka wamafasitela ayisiyingi kanye nesikwele anobubanzi obufanayo uyafana, futhi indawo yesiyingi incane kunaleyo yesikwele.Ububanzi bokudlulisa ukukhanya kwewindi lokubuka eliyindilinga lobubanzi obufanayo bungaphansi kwewindi lokubuka lesikwele, ngakho-ke kungcono kakhulu ukukhetha iwindi lokubuka eliyisikwele.
