Iyini ukusebenza kwenethi yocingo lwe-aluminium kanye nenethi yokuphepha? Ingabe zinhle kakhulu ngempela?
Inethi yokuvikela i-aluminium, eyaziwa nangokuthi inethi yokuphepha, isetshenziswa kakhulu ezindongeni ezahlukahlukene, ophahleni lwezimo eziphuthumayo zezokwelapha, ophahleni lwebhizinisi nezindawo zokuvakasha kanye nophahla lwezakhiwo ezahlukahlukene eziphakeme. Uma ubuso be-helipad yophahla buphakeme ngaphezu kwama-75cm (noma ama-0.75m) kunemvelo ezungezile, futhi kuzoba nezingozi zokuphepha ezenzweni zabasebenzi, inethi yokuphepha kufanele ifakwe ku-helipad. Akukho ukugcizelela okukhulu ekufakweni kwamanethi okuphepha kwezinye izindawo. Izici nezinzuzo zenethi yokuphepha:
Inethi yokuphepha yenziwe ngezinto eziqinile ze-aluminium alloy, ezingathwala amandla amakhulu okushaya futhi zingathwala isisindo esingama-300kg. Ukuze kubhekane nezingozi zomlilo ezingaba khona, inethi yokuphepha ngokwayo isebenza kahle ekuvimbeleni umlilo. Indawo ye-apron iyinkimbinkimbi futhi iyashintshashintsha, kanti inethi yokuphepha inokumelana okuhle nesimo sezulu kanye nokumelana nokugqwala ukuze ibhekane nezimo zezulu ezinzima njengokushisa okuphezulu, izinga lokushisa eliphansi, imvula kanye neqhwa.
Ukufakwa kwenethi yokuphepha kufanele kulandele isiqondiso sochwepheshe ukuqinisekisa ukufakwa okuqinile nokuzinzile. Ngesikhathi esifanayo, kuyadingeka futhi ukucabangela ukuhlanganiswa phakathi kwenethi yokuphepha nendawo ezungezile (njengezakhiwo nemishini). Kubalulekile ukuhlola nokugcina inethi yokuphepha njalo. Okuqukethwe kokuhlola kufaka phakathi kodwa akukhawulelwe ekuthembekeni kwenethi yokuphepha, umthamo wokuthwala, ukuthi iphuzu eliqinile likhululekile, njll. Uma kutholakala noma yimuphi umonakalo noma ukungajwayelekile, kufanele kulungiswe noma kushintshwe ngesikhathi.
