Njengengcezu yesisetshenziswa esibalulekile sezokuthutha ezibandayo, ukukhethwa kwe-semi{0}}trailer eqandisiwe kubalulekile. Lapho ukhetha i-trailer, cabangela izici ezintathu ezibalulekile: i-trailer chassis, umzimba ovalelwe, kanye neyunithi yesiqandisi.
Ukubaluleka Kokukhethwa Kwe-Chassis
I-chassis ithinta umthamo wemoto othwalayo, ukusetshenziswa kukaphethiloli, namazinga okukhishwa kwegesi. Khetha i-chassis ethembeke kakhulu futhi iletha ngokushesha ukuze uvimbele ukungasebenzi kahle okungadala ukonakala kwempahla. Okokuqala, ukukhetha chassis kubalulekile. Ithinta ngokuqondile umthamo wemoto yokuphatha, ukusetshenziswa kukaphethiloli, namazinga okukhishwa kwegesi. Ngaphezu kwalokho, njengoba ama-trailer afakwe esiqandisini{4}}ejwayele ukuthutha impahla ngokushesha futhi awakwazi ukugcinwa isikhathi eside, ukwethembeka kwe-chassis kubaluleke kakhulu ukuvimbela ukungasebenzi kahle okungabangela ukuwohloka kwempahla.
Imibandela Yokukhetha Umzimba
Okwesibili, umzimba kufanele ube nezimpawu ezinhle kakhulu zokuvala kanye nezindawo zokushisa ezishisayo. Izinto ezisetshenziswayo kufanele zibe nokumunca amanzi aphansi, ziphefumule, futhi zingagqwali{1}}zimelane nezinhlobo ezahlukene zempahla. Umzimba udinga ukubekwa uphawu okuhle kakhulu kanye nokufakwa kwe-thermal ukuqinisekisa izinga lokushisa elizinzile lempahla ngesikhathi sokuthutha. Lapho ukhetha umzimba, cabangela ukumuncwa kwamanzi okubalulekile, ukuphefumula, ukuqhutshwa kwe-thermal, nokumelana nokugqwala. Ngaphezu kwalokho, izinhlobo ezahlukene zempahla zizoba nezidingo ezihlukene ze-trailer, ngakho ukukhetha kufanele kuncike ezidingweni zangempela.
Ukukhethwa kweyunithi yesiqandisi
Ekugcineni, amayunithi esiqandisi ahlukaniswe abe izinhlobo ezizimele nezincikile. Lapho ukhetha iyunithi yesiqandisi, kubalulekile ukulinganisa izidingo zokuhamba ukuze ugweme izindleko eziphezulu. Ukukhethwa kweyunithi yesiqandisi nakho kuyisici esibalulekile ekunqumeni ukusebenza kwe-semi{2}}trailer yesiqandisi. Amayunithi esiqandisi ahlukaniswa njengezizimele futhi ancike. Amayunithi azimele anomthombo wawo wamandla, kuyilapho amayunithi ancikile athembele emandleni ka-chassis wemoto. Lapho ukhetha iyunithi yesiqandisi, kubalulekile ukulinganisa izidingo zokuhamba ukuze ugweme izindleko zokuthutha ezingadingekile.
