Emva kokuba ipleyiti ifakwe kwipleyiti, indlela yoyilo I-Engela kunye nokusuka kwayo I-Engela yesithuthi ayizukuchaphazeleka.
Ipleyiti yepleyiti engaphambili efakwe kwi-bumper engaphambili yesithuthi 2. Ipleyiti yepleyiti efakwe kwipleyiti yepleyiti engaphambili mayibe yi-engile okanye iphantse ibe yi-engile kwi-longitudinal plane yolingano lwesithuthi, umbindi wepleyiti engaphambili akufuneki ube kwicala lasekhohlo le-longitudinal plane yolingano lwesithuthi, kwaye ipleyiti engaphambili kunye ne-plate bracket akufuneki zidlule kumda osekunene wesiphelo esingaphambili sesithuthi.
Ipleyiti efakwe kwipleyiti engaphambili mayibe ngqo kwicala elithe tye, kwaye ipleyiti engaphambili ayifanele ivunyelwe ukuba ithambekele ngasemva ngaphezu koko.
Ipleyiti yelayisensi engasemva eyi-15° kufuneka ibekwe ngasemva kwesithuthi. Ipleyiti yelayisensi efakwe kwipleyiti yelayisensi engasemva mayibe yicala elithe nkqo okanye iphantse ibe yicala elithe nkqo kumgca wokulinganisa ubude besithuthi kwaye mayibe kwicala lasekunene lomgca wokulinganisa ubude besithuthi. Ipleyiti yelayisensi engasemva kunye nesibiyeli sepleyiti yelayisensi akufuneki idlule umda wasekhohlo wesiphelo sangaphambili sesithuthi. Xa ukuphakama komphetho ophezulu wepleyiti engasemva ngaphezu komhlaba kungaphezulu kwe-1.2m, ukuphakama komphetho wangaphambili wepleyiti engasemva ngaphantsi komhlaba kungaphezulu kwe-30°
15 °
