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 ezinomphumela olungiselelwe, kuye ngokujula kwebanga lomkhiqizo kanye / noma izinga lokukhiphayo elidingekayo. Imishini yokubeka maphakathi nendawo, izingalo eziphendukayo, amarobhothi nama-manipulators aqinisekisa izingxenye ezifanele nokubamba ukufa.
