A ukuphakamisa uchungechungeiyithuluzi lomshini elisebenzisa uchungechunge ukuphakamisa nokwehlisa umthwalo. Lisekelwe esimisweni esilula kodwa esisebenzayo esihlanganisa inzuzo yomshini kanye ne-leverage. Ukuqonda izimiso zokuphakamisa uchungechunge kubalulekile kunoma ubani ohilelekile emisebenzini yokuphakamisa embonini yokwakha, yokukhiqiza noma yokugcina impahla.
Ingaphakathi le-chain hoist liqukethe uchungechunge, uhlelo lwe-pulley kanye nendlela yokuphakamisa. Uchungechunge luzungezwe uchungechunge lwama-pulley afakwe kufreyimu. Lapho opharetha edonsa kolunye uhlangothi lochungechunge, kukhiqizwa amandla adluliselwa ngama-pulley, okwandisa ngempumelelo amandla okuphakamisa. Le nzuzo yomshini yenza umuntu oyedwa akwazi ukuphakamisa umthwalo obekungenakwenzeka ukuwuhambisa ngesandla.
Isimiso sokuphakamisa iketanga sisekelwe emibonweni ye-torque kanye nokusatshalaliswa komthwalo. Lapho opharetha edonsa iketanga, amandla asatshalaliswa kuwo wonke ama-pulley, okunciphisa amandla adingekayo ekuphakamiseni. Uma ama-pulley amaningi ohlelweni, kuba lula ukuphakamisa into esindayo. Ngakho-ke, ama-chain hoist avame ukuhlonyiswa ngama-pulley amaningi ukuze kwandiswe amandla okuphakamisa.
Ngaphezu kwalokho, ama-chain hoist angasetshenziswa ngesandla noma aqhutshwe uhlelo lukagesi noma lomoya. Nakuba ama-chain hoist asetshenziswa ngesandla edinga amandla angokomzimba kumqhubi, ama-chain hoist kagesi enza inqubo yokuphakamisa ibe lula, okwenza isheshe futhi isebenze kahle.
