Ukutshintsha kufakwe kwi-cab, kwaye i-pin yokhuseleko inokufakwa ngokucofa nje iqhosha lokutshintsha kwi-cab.Ngoko ke, inkathazo yokuphuma kwi-cab igcinwe.Itekhnoloji entsha yokuvula kunye nokuvala ipini yokhuseleko ifezekiswa ngokusetyenziswa kwenkqubo yombane yomqhubi we-excavator, kunokuba inkqubo ye-hydraulic.Ngoko ke, uxinzelelo lweoli oluphezulu lutshintshwa ngumbane, ogcina iindleko kwimveliso.Kwi-cab, isandi esizenzekelayo sesigodlo singasetyenziselwa ukugqiba ukuba idibaniswe.Kwimeko yocingo oluphukileyo, ukhuseleko lokuguqulwa kwencwadana lunokuqinisekiswa.
