Ngaba unomdla wokwazi ukuba ingahamba kangakanani na i-semi-lori? Abantu abaninzi banjalo, ngakumbi ngelixa beqhuba ecaleni komnye kuhola wendlela. Ngelixa isantya se-semi-lori sihluka ngokuxhomekeke kubunzima kunye nobukhulu bomthwalo ewuthweleyo, kunye nezinye izinto, akukho santya siphezulu esisemthethweni kwezi zithuthi. Nangona kunjalo, iilori ezininzi zinesantya esiphezulu se-55 kunye ne-85 yeemayile ngeyure. Umda othile uxhomekeke kwimeko apho ilori iqhuba khona. Umzekelo, iCalifornia inomlinganiselo wesantya esiphezulu seemayile ezingama-55 ngeyure kwiilori.
Xa kuthelekiswa, iTexas ineendlela ezithile ezinesantya esiphezulu somda welori oziikhilomitha ezingama-85 ngeyure. Ukwahluka kukuba urhulumente ngamnye ubeka imilinganiselo yesantya esekelwe kwizinto ezifana neemeko zendlela kunye nokuxinana kwezithuthi. Nangona kunjalo, nokuba zikweyiphi na imeko, zonke iilori kufuneka zilandele isantya esibekiweyo ukuze zigcine ukhuseleko ezindleleni. Ke ukuba ukhe waphuma endleleni evulekileyo kwaye ubone i-rig enkulu iza ngendlela yakho, zilungiselele ukuphuma endleleni.

Ngaba i-semi ukuya 100 mph?
Bambalwa abanokulinganisa ubukhulu kunye namandla e-semi-lori xa kuziwa kwizithuthi ezihamba phantsi. Iyakwazi ukurhuqa imithwalo emikhulu kwimigama emide, ezi behemoth zikahola wendlela zezinye zezona matshini zinomtsalane endleleni. Kodwa banokuhamba ngokukhawuleza kangakanani? Ngelixa i-semi-lori ephakathi inesantya esiphezulu esimalunga nama-55 mph, ezinye iimodeli zinokufikelela kwisantya esingaphezulu kwe-100 mph. Enye ilori yokulahla i-Peterbilt 379 yavalwa, ihamba i-113 mph kuhola wendlela yaseFlorida ngo-2014. Ngoko ngelixa ungafuni ukucela umngeni kwi-semi kugqatso nangaliphi na ixesha kungekudala, kucacile ukuba ezi lori ziyakwazi ukufikelela kwizantya ezinzulu.
Ingaba isiqingatha singaya kude kangakanani kwitanki egcweleyo?
Ngokutsho kolunye uqikelelo, ii-semi-lori zinokuhamba umgama omde kwitanki enye yamafutha - ukuya kuthi ga kwiikhilomitha ezingama-2,100. Kungenxa yokuba ezi zithuthi zikhulu zihlala zineetanki zamafutha ezigcina malunga neelitha ezingama-300 zedizili. Ngaphezu koko, bakholisa ukuba nokusebenza kakuhle kwepetroli, umndilili omalunga neekhilomitha ezisi-7 ngegaloni nganye. Kakade ke, bonke abaqhubi belori kufuneka bazi ubungakanani betanki yamafutha kunye nelori yabo esebenza ngokufanelekileyo.
Zingaphi iigiya enazo isemi-lori?
Iilori eziqhelekileyo zineegiya ezilishumi. Ezi zixhobo ziyimfuneko ukuze ucuthe kwaye ukhawuleze xa urhuqa ubunzima obunzima kwiindlela ezahlukeneyo kunye neendawo. Iilori ezineegiya ezininzi zinokuhamba ngokukhawuleza kwaye zirhuqe ubunzima obuninzi, kodwa kubiza kakhulu ukuzigcina. Xa ilori ineegiya ezininzi, igiya nganye kufuneka ikwazi ukumelana nobunzima obuninzi, nto leyo ethetha ukuba injini kunye nokuhanjiswa kufuneka komelele. Ngenxa yoko, iilori ze-13-, 15- kunye ne-18-speed-speed zikholisa ukufunyanwa kuphela kwizicelo zohambo olude. Olunye uhlobo lwelori, ebizwa ngokuba yiSuper 18, inezantya ezili-18, kodwa ukuhanjiswa kumiswe ngokwahlukileyo kancinci. Le lori isetyenziswa kakhulu kwizicelo ezingaphandle kwendlela, njengokugawulwa kwemithi kunye nemigodi. Ezinye iinkampani ezisebenza ngolu hlobo lwelori ziphuhlise uthumelo lomnini ngezixhobo ezingakumbi; nangona kunjalo, ezi azikho umgangatho kushishino lwelori.
Ingaba isantya esinamavili angama-18 sihamba kangakanani?
Izithuthi zorhwebo ezifana ne-18-wheelers zakhelwe isantya kunye nokusebenza kakuhle. Abaqhubi bezi lori zikhulu baqeqeshelwa ukuziqhuba kwiimeko ezahlukeneyo. Ngenxa yoko, banokuhamba ngokuzithemba koohola bendlela kunye ne-interstates ngesantya esiphezulu. Iilori ezimfutshane ziyakwazi ukuhamba ngesantya esingaphezu kweemayile ezili-100 ngeyure, kwaye abanye abaqhubi bade bafikelela kwisantya seemayile ezingama-125 ngeyure. Ukongeza, i-18-wheelers inokukhawulezisa ukusuka kwi-0-60 yeemayile ngeyure ngemizuzwana eyi-15 ukuba akukho trailer encanyathiselwe kubo. Ngelixa umqhubi oqhelekileyo usenokungaze afune ukufikelela kwezi zintya, kuyakhuthaza ukwazi ukuba ezi nqwelo-mafutha zikhulu ziyilelwe ukuba ziziphathe ngokulula.
Ngaba iilori eziziisiqingatha ziyazenzekela?
Kangangeminyaka, uthumelo lwezandla lwaluyinto eqhelekileyo kwiitrayila ezizii-semi-trektara. Nangona kunjalo, oko kuyatshintsha. Baya besanda abavelisi belori abancinci banikezela ngeelori ezizihambelayo (AMTs). Ii-AMTs ziyafana nokuhanjiswa kwezandla zemveli, kodwa zinekhompyuter eyenza ukutshintshwa kweegiya. Oku kunokubonelela ngeenzuzo ezininzi kubaqhubi belori, kubandakanywa uqoqosho oluphuculweyo lwamafutha kunye nokuncipha kokuguga kunye nokukrazula kuthumelo. Ukongeza, ii-AMTs zinokwenza kube lula ukuba abaqhubi bagcine isantya esingaguqukiyo, esinokubaluleka ekuhlangabezaneni nemihla yokugqibela yokuhanjiswa. Njengoko uqoqosho luqina, iinkampani zelori ziya kutshintshela kwii-AMTs ukuphucula umgca wabo osezantsi.
Uninzi lwabantu lucinga ukuba umqhubi welori kufuneka akhathazeke kuphela ngesantya xa exinzelela kuhola wendlela, ezama ukwenza ixesha elifanelekileyo. Nangona kunjalo, isantya sibaluleke kakhulu xa ilori iqhobosha kwaye idala umsantsa omncinci phakathi kwayo kunye nesithuthi esingaphambili. Ukuba ilori ihamba ngokukhawuleza, kuya kuthatha ixesha elide ukuyeka, ukwandisa umngcipheko wokuphelisa imoto ngaphambili okanye i-jackknifing. Yiyo loo nto kubalulekile ukuba abaqhubi belori bathobele isantya esibekiweyo, naxa bengekho kuhola wendlela. Ngokunciphisa isantya sabo, banokunceda ekuthinteleni iingozi kwaye bagcine wonke umntu osendleleni ekhuselekile.
