Ingabe ufuna ukwazi ukuthi i-semi-loli ingahamba ngesivinini esingakanani? Abantu abaningi banjalo, ikakhulukazi ngenkathi beshayela eduze nomunye kuthelawayeka. Nakuba ijubane le-semi-truck liyahlukahluka kuye ngesisindo nobukhulu bomthwalo eliwuthwele, kanye nezinye izici, asikho isivinini esiphezulu esisemthethweni salezi zimoto. Kodwa-ke, ama-semi-truck amaningi anomkhawulo wejubane elikhulu lamamayela angama-55 no-85 ngehora. Umkhawulo othize uncike esimweni lapho iloli lishayela khona. Isibonelo, iCalifornia inomkhawulo wesivinini esingamamayela angu-55 ngehora emalolini.
Uma kuqhathaniswa, iTexas inemigwaqo ethile enesivinini esiphezulu somkhawulo weloli wamamayela angu-85 ngehora. Okuhlukile ukuthi umbuso ngamunye ubeka imikhawulo yejubane ngokusekelwe ezicini ezifana nezimo zomgwaqo nokuminyana kwezimoto. Kodwa-ke, kungakhathalekile ukuthi akusiphi isimo, wonke amaloli kufanele ahambisane nesivinini esibekiwe ukuze agcine ukuphepha emgwaqeni. Ngakho-ke uma uke waphuma emgwaqeni ovulekile futhi ubona isikhonkwane esikhulu esiza endleleni yakho, zilungiselele ukuphuma endleleni.
Okuqukethwe
Ingabe i-semi ingakwazi ukuhamba u-100 mph?
Bambalwa abangakwazi ukufanisa ubukhulu namandla e-semi-truck uma kuziwa ezimotweni ezihlala phansi. Ikwazi ukudonsa imithwalo emikhulu ebangeni elide, la mabhemu omgwaqo onguthelawayeka angeminye yemishini ehlaba umxhwele kakhulu emgwaqeni. Kodwa bangahamba ngesivinini esingakanani? Ngenkathi iloli eliphakathi nendawo linesivinini esiphezulu esingaba ngu-55 mph, amanye amamodeli angafinyelela isivinini esingaphezulu kuka-100 mph. Iloli elilodwa lokulahla i-Peterbilt 379 lavalwa, lihamba ibanga elingu-113 mph kuthelawayeka waseFlorida ngo-2014. Ngakho-ke nakuba ungase ungafuni ukubekela inselelo ingxenye yomjaho noma nini maduze, kuyacaca ukuthi lamaloli ayakwazi ukufinyelela isivinini esithile esibucayi.
Ingxenye ingahamba ibanga elingakanani kuthangi eligcwele?
Ngokwezinye izilinganiso, ama-semi-loli angahamba ibanga elide ethangini elilodwa likaphethiloli - afinyelele kumamayela angu-2,100. Lokhu kungenxa yokuthi lezi zimoto ezinkulu zivame ukuba namathangi kaphethiloli abamba cishe amalitha angama-300 kadizili. Ngaphezu kwalokho, zivame ukusebenza kahle kakhulu kuphethiloli, isilinganiso esingamamayela angu-7 ilitha ngalinye. Kunjalo, bonke abashayeli bamaloli angama-semi-truck badinga ukwazi ubukhulu bethangi labo likaphethiloli kanye nesilinganiso sokusebenza kahle kwamafutha eloli labo.
I-semi-truck inamagiya amangaki?
Ama-semi-truck ajwayelekile anamagiya ayishumi. Lawa magiya ayadingeka ukuze wehlise ijubane futhi usheshise lapho udonsa isisindo esindayo ezindaweni ezihlukene kanye nezindawo. Ama-semi-truck anamagiya amaningi angahamba ngokushesha futhi adonse isisindo esiningi, kodwa futhi kubiza kakhulu ukuzinakekela. Uma iloli linamagiya engeziwe, igiya ngalinye kufanele likwazi ukumelana nesisindo esiningi, okusho ukuthi injini namagiya kufanele kuqine. Ngakho-ke, amaloli angu-13-, 15- kanye ne-18-speed ngokuvamile atholakala kuphela ezicelweni zokudonsa isikhathi eside. Olunye uhlobo lweloli, olubizwa ngeSuper 18, lunamajubane angu-18, kodwa ukudluliselwa kwalo kuhlelwe ngokuhlukile. Leli loli lisetshenziselwa kakhulu izicelo ezingekho emgwaqeni, njengokugawulwa kwemithi nezimayini. Ezinye izinkampani ezingochwepheshe kulezi zinhlobo zamaloli zenze ukuthunyelwa kobunikazi ngamagiya engeziwe; Nokho, lezi akuzona standard embonini yamaloli.
Ihamba ngokushesha kangakanani i-18-wheeler?
Izimoto zezentengiselwano ezifana namasondo angu-18 zenzelwe isivinini nokusebenza kahle. Abashayeli balamaloli amakhulu baqeqeshelwe ukuwasebenzisa ezimeni ezihlukahlukene. Ngenxa yalokho, angakwazi ukuzulazula emigwaqweni emikhulu ngokuzethemba nasezimpambanweni zezifunda ngesivinini esikhulu. Ama-semi-truck angahamba ngesivinini esingaphezu kwamamayela ayi-100 ngehora, kanti abanye abashayeli sebeze bafinyelela isivinini samamayela ayi-125 ngehora. Ngaphezu kwalokho, amasondo angu-18 angakwazi ukusheshisa ukusuka kumakhilomitha angu-0-60 ngehora ngemizuzwana engu-15 uma ingekho i-trailer enamathiselwe kuwo. Nakuba umshayeli ovamile engase angalokothi adinge ukufinyelela kulezi zivinini, kuyasiduduza ukwazi ukuthi lezi zimoto ezinkulu zenzelwe ukuzibamba kalula.
Ingabe ama-semi-trucks ayazenzakalela?
Iminyaka eminingi, ukuhanjiswa okwenziwa ngesandla kwakuyinto evamile kuma-semi-tractor-trailer. Nokho, lokho kuyashintsha. Bayanda abakhiqizi bamaloli amancane banikezela ngamaloli asebenza ngokuzenzakalelayo (AMTs). Ama-AMT ayafana namagiya ajwayelekile, kodwa anekhompyutha eshintshashintsha amagiya. Lokhu kunganikeza izinzuzo ezimbalwa kubashayeli bamaloli, okuhlanganisa ukonga uphethiloli okuthuthukisiwe kanye nokuncipha kokuguga nokuguga ekudluliseni. Ngaphezu kwalokho, ama-AMT angenza kube lula kubashayeli ukuthi balondoloze isivinini esingaguquguquki, okungabaluleka ukuze kuhlangatshezwane neminqamulajuqu yokulethwa. Njengoba umnotho uqina, izinkampani zamaloli cishe zizoshintshela kuma-AMT ukuze zithuthukise umugqa wazo.
Iningi labantu licabanga ukuthi umshayeli weloli udinga kuphela ukukhathazeka ngesivinini lapho eshaya emgwaqeni omkhulu, ezama ukwenza isikhathi esihle. Nokho, isivinini sibaluleke ngendlela efanayo lapho iloli libhuleka futhi lidala igebe elincane phakathi kwalo nemoto engaphambili. Uma iloli lihamba ngesivinini esikhulu, kuzothatha isikhathi eside ukuthi lime, okwandisa ingozi yokumisa imoto ngaphambili noma i-jackknifing. Yingakho kubaluleke kakhulu ukuthi abashayeli bamaloli bahloniphe isivinini esibekiwe, ngisho nalapho bengekho emgwaqweni onguthelawayeka. Ngokunciphisa ijubane labo, bangasiza ekuvimbeleni izingozi futhi bagcine wonke umuntu osendleleni ephephile.
