Kunezinhlobo ezintathu zesithupha se-hydraulic: i-weld ekhuphukayo ohlotsheni, uhlobo lwephini eliyinhloko, nohlobo lwesixhumanisi esiqhubekayo.Isithupha sohlobo lwesixhumanisi esiqhubekayo sinobubanzi bokusebenza obusebenza kangcono kunohlobo lwephinikhodi eyinhloko, kuyilapho uhlobo lwephinikhodi eyinhloko lungcono kune-weld efakwayo ohlotsheni.Ngokusebenza kwezindleko, uhlobo lwephinikhodi eyinhloko kanye ne-weld ekhulayo ohlotsheni lungcono kakhulu, okubenza badume kakhulu emakethe.Kwa-Crafts, ububanzi nenani lezinombolo zesithupha lingenziwa ngendlela oyifisayo ngokuya ngesidingo sakho.
