Okwangoku, kukho iindidi ezimbini zeesemi{0}}itreyila ekhenkcezisiweyo.
Uhlobo lokuqala, itreyila edityanisiweyo, ibhekiselele kwinqwelo erhuqwayo ekumgangatho ophakathi efriji -enomzimba kunye nesakhelo esingenokwahlulwa. Ezi nqwelwana -ezirhuqwayo ziwela phantsi kodidi lwelori ezifakwe efrijini, ezinomphakamo ongekho ngaphezulu kwe-4 yeemitha, ubude obuyi-13.6 yeemitha, kunye nobubanzi obuziimitha ezi-2.6.
Udidi lwesibini, itreyila eyahlulahlulayo, ibhekisa kwisikhongozeli sesemi{0}}esikhenkcezisi esinesiqingatha esinomzimba kunye nesakhelo. Ezi ngokuqhelekileyo ziza kwiindidi ezimbini: enye yinqwelwana ye-45-foot skeletal (i-13.95 yeemitha) edonsa isikhongozelo esiqhelekileyo esisefrijini, esiziimitha ezingama-45 ubude kunye neemitha ezi-2.55 ububanzi.
Olunye uhlobo yitreyila engama-45-yeenyawo yamathambo etsala umkhongozeli oguqulweyo ukusuka kwisikhongozelo saselwandle esisetyenzisiweyo, esiziimitha ezingama-45 okanye ezingama-48 ubude kunye neemitha eziyi-2.438 ububanzi. Olu hlobo lwesikhongozeli semi-trailer esikhenkcezisiweyo sisongamela imakethi{6} iitreyila zamathambo onyawo azisavumelekanga eChina.
