Umgomo wokusebenza womshini wokunyathelisa we-hydraulic uyindlela yokudlulisa esebenzisa umfutho we-liquid ukudlulisa amandla nokulawula.Idivayisi ye-hydraulic yenziwe ngamaphampu we-hydraulic, ama-cylinders we-hydraulic, ama-valve okulawula ama-hydraulic kanye nezingxenye ezisizayo ze-hydraulic.I-hydraulic transmission system yomshini wokucindezela we-hydraulic wekholomu emine iqukethe indlela yamandla, indlela yokulawula, i-executive mechanism, i-auxiliary mechanism kanye ne-work medium.Indlela yamandla ngokuvamile isebenzisa iphampu kawoyela njengendlela yamandla, esetshenziswa kakhulu ekukhipheni, ekugobeni, ekudwebeni okujulile kwamapuleti ensimbi engenasici kanye nokucindezelwa okubandayo kwezingxenye zensimbi.
