Iziqwire ezikhanyisiweyo zokwenziwa zineziko elikhulu kakhulu, zenza iizithuthi neziqhumatha zilandelelanayo kwaye zinzuzile ngokokwenyani xa bathetha ngazo. (Iziqwire eziphezulu zokwenziwa zingakunceda iizithuthi neziqhumatha zilandelelanayo kwaye zinzuzile ngokokwenyani xa bathetha ngazo.) Ke noku masithi ngakumbi ngokusebenzisa iistel wire ukwenza iizithuthi neziqhumatha ziyinto ephakamileyo.

Izithuthi/ziqhumatha neziko elikhanyisiweyo (kwiistel wire):

Iziqwire zokwenziwa zifana neziqwire ezikhanyisiweyo ezingasemgangathweni zisebenziswa ukwenza iizithuthi neziqhumatha zinzuzileyo. Ngenkqubo yokuqala iistel wire kwiinkqubo zokubhala kwaye kwezinye izinto zokwenziwa, ubukhosi beqondo elipheleleyo buphuculwa. Le nto ngoko ke iizithuthi neziqhumatha zinokuthetha ngokuphezulu - kwaye zilindelele ngokuphezulu kwezixhobo, njengomoya kwaye nezithuthi - ngaphandle kokuchithwa. Iziqwire zokwenziwa zisebenzisa nezinye izinto ukwenza umqamleli ophakamileyo kwaye onzuzileyo osebenziswe nguMntu.

Ukusebenza ngokweqile kweziqwire zokwenziwa kwiinkqubo yokukhanyisa:

“Yinto enkulu yokuba yindlela esebenzisa ngokwemininingwano yokwenza iibridge neentlango zikhstrongke,” Andithi uMichael Stevens, umathisi wokwenza iibridge kwiColorado Department of Transportation. Zinokubandakanywa kwiingcubungu ezikhstronge ezingezinto eziphindwa ngazo ukuze zikhankanye. Iindlela zokwehla zokwehla zinokubulwa ukuze zenze iindlela, ezo ke zisetyenziswa ukuze isetha iibridge neentlango. Ukuhlala koku kubonelela abathisi ukufumana iindlela ezintsha zokusebenzisa amakhawuti nokwenza umthombo ophakeme kwaye ulunge ngempela.

Ukukhululeka okuningi kunye nokwehla okuphezulu ngokusebenzisa iindlela zokwehla zokukhankanya:

Iintaba kunye neetuneli enamacala amabili ayanqaniselwa kwaye zinezinto ezingasemntu apho okanye zokugqitywa. Lokhu kubangela ukuba zivele ngemva kwezikhathi ezininzi kwaye zenze ngokulawulwa ngokulawulwa kwezikhathi. Le macala amabili ayakhuselela umda wokwenza amacala kwaye ayakhuselela umda kwiindlela ezingasemntu zokulawulwa okanye zenza ukuba umda uphucule. Ukwakhiwa kwezintaba kunye neetuneli ngamacala amabili kuya kuvumela ukuba zibe yimali abantu bakusebenzisa ngemva kwezikhathi ezininzi.

Iindlela ezintsha zokusebenzisa macala amabili ngokukhuthaza okukhulu:

Kunye nakwe ndlela entsha kunye nekhuthaza apho abasebenzisi bethu bathola indlela yokusebenzisa amakhawuti ukuthutha ubunzima obukhulu bekhona okanye ityhubhu. Abasebenzisa amaweyiri edolomithi efanisekileyo ukuthumela amandla wokuthutha ubunzima apho akudingekayo futhu kuthulas ukuba yini ubunzima obudingekayo ukuthuthwa ngokuphelele. Lokhu kuthibela ukuthiwa kakhulu kuthuthwe ubunzima, ngakho ke kunceda abantu abaphakathi. Imisebenzi yamaweyiri edolomithi yezintsha iyavuleka futhu kuthuthwe kwekhona neityhubhu.
