Kuphuculo lweshaft ejikeleziswayo kwindawo ebifudula iyisibambi esetyenziswa kwinkqubo yokwenziwa kweemveliso zelatex eziditshiweyo apho ishafti idityaniswe neyunithi edityanisiweyo kwikhonkco lokuhambisa kunye nebhodi eqengqelekayo ehlala yangaphambili.umntu owayefudula ephethe uquka iqumrhu eliqengqelekayo elinesiqingatha sokuphumla esisembindini (15) ukulungiselela owayesakuba;i-shaft ye-cross-section shaft efakwe kwaye ikhuselekile kumzimba we-roller kwaye;ukutshixa kuthetha ukubamba nokutshixa eyokuqala.iqumrhu eliqengqelekayo lomnini wangaphambili onesikhokelo sangaphambili esibekwe kwindawo esembindini kwindawo yekhefu kwaye sidibana ngokudibana nokuvuleka komlomo kowokuqala.ishafti enecandelo elinqamlezileyo elimilo engu-d kwelinye icala elikhuselweyo ngokutshixwa lithetha ukuba libunjwe ngokubonakalayo kwi-engile yasekunene kwisikhokhelo sangaphambili;esinye isiphelo se-shaft sidityaniswe kwiyunithi yokudibanisa ehambelana nekhonkco lokuhambisa.indlela yokutshixa iyashenxiswa ecaleni komgca ohamba ecaleni weshafti ngendlela ecalanye yesibambi iseti kwaye ivulwe ngesenzo sentlakohlaza yendlela ecalanye yokukhusela nokutshixa yangaphambili ngokuqinileyo.

Ulungiselelo kunye nendlela yokudibanisa abanini bangaphambili” idiza ilungiselelo kunye nendlela yokuhlanganisa abo babefudula bengabanini-ndawo endaweni yesiqhelo yalowo wayekade ephethe indlela yokwandisa ubuninzi kunye nemveliso kwimveliso yeeglavu.Indlela yokudibanisa abo babefudula bengabanini kwimveliso yeeglavu yopapasho olubhengeziweyo ibandakanya isikhonkwane esincanyathiselwe ekupheleni kweshafti nganye ekhankanyiweyo esuka kwitsheyini ekhankanyiweyo;iihenjisi ezimbini ezincanyathiselwe kwiphini nganye ithwala isibambi esincamatheleyo, okuthetha ukuba ababini ababefudula bangabanini babelana ngolwandiso lweshafti enye, apho iperi yeehenjisi kulwandiso lweshafti enye iya kuba nenye phezu kwenye ngexesha lemveliso yeglavu kunye nesibini sabaphathi bangaphambili. Ekupheleni kweshafti zolwandiso ngalunye ezikhankanyiweyo zahlulwe ngesibini sabanini bangaphambili sithambethekile ngamadigri angama-90 ukusuka kwindawo ebekuyo ngexesha leenkqubo ezinjengokushicilela kunye nokuhlutywa kweglavu.Nangona kunjalo impumelelo yokuhluthwa kolu lungiselelo lungentla lwabanini bangaphambili ayikafikeleli kwinqanaba elifunekayo.Ngaphezu koko, ngolu lungiselelo lungasentla kukho amathuba okudlula iiglavu ngexesha lenkqubo yokuhlutha, ephinda inciphise ukusebenza kakuhle kwenkqubo yokuvelisa iiglavu.
