Umsebenzi wokuqala wokwakha lapho ukhiqiza izindandatho ezingenamthungoukuqamba izikhala zendandatho. Imigqa egoqayo ishintsha lezi zibe izandulela zokuthwala amagobolondo, amagiya omqhele, ama-flange, amadiski ophephela ezinjini zejethi nezinto ezihlukahlukene zesakhiwo esigcizelelwe kakhulu.
Imishini yokunyathelisa ye-hydraulic ifaneleka kakhuluukuqamba izikhala zendandatho: Amandla aphezulu, imivimbo emide kanye nomthamo olinganiselwe onganqunyelwe yizici ezidingekayo ukuze kufoshwe iringi engenalutho esebenzayo. Kusetshenziswa imigqa eguquguquka kakhulu noma izinqubo zeziteshi eziningi ezinokuphuma okuthuthukisiwe zisetshenziswa, kuye ngokujula kwebanga lomkhiqizo kanye / noma izinga lokuphumayo elidingekayo. Imishini yokubeka maphakathi nendawo, izingalo eziphendukayo, amarobhothi nama-manipulators aqinisekisa izingxenye ezifanele nokubamba ukufa.
