1. Isilungiselelo sobude obuzenzakalelayo somshini wokubuyisela emuva itheyiphu: isibali sobude esinezinyathelo ezimbili sinikeza isilawuli esinembile sokubuyisela emuva ubude.Uma ubude besethi bufinyelelwe, i-servo motor iyamukelwa ukuze ama-shafts azoshintsha ngokushesha nangokuzenzakalelayo, aqinisekise ukusebenza okulula nokusebenza kahle.
2. Isilawuli esihlelekayo somshini wokubuyisela emuva itheyiphu: isilawuli esihlelekayo sokusebenza okuphezulu sinikeza ukulawula okulula kwawo wonke umsebenzi wokubuyisela emuva.Kokubili ubude nokuqina kuboniswa ngokunembile ngokufundwa kwe-LCD.
3. Umnyombo wephepha lomshini wokubuyisela itheyiphu ugxiliswe ku-pneumatic shaft.kalula, ukulayisha okusheshayo nokuthulula, kuthuthukisa kakhulu ukusebenza kahle.
4. Umshini wokubuyisela emuva itheyiphu idivayisi yokushelela okuzenzakalelayo (ongakukhetha): le divayisi yokusula iyiqeda ngokugcwele inkinga yokushwabana namabhamuza omoya emkhiqizweni ngemva kokuhlehlisa.Le divayisi iqinisekisa futhi ukushelela komkhiqizo.
