Ngenxa yokuthi ukwakheka kwe-crane kuyinkimbinkimbi kakhulu futhi kukhulu, kuzokwandisa ukwenzeka kwengozi ye-crane ngezinga elithile, okuzobeka usongo olukhulu ekuphepheni kwabasebenzi. Ngakho-ke, ukuqinisekisa ukusebenza okuphephile kwemishini yokuphakamisa sekuyinto ebaluleke kakhulu ekuphathweni kwemishini ekhethekile yamanje. Lesi sihloko sizohlaziya izingozi ezifihliwe zokuphepha kuwo wonke umuntu ukuze agweme izingozi ngesikhathi.
Okokuqala, izingozi zokuphepha ezifihliwe kanye nokukhubazeka zikhona emshinini wokuphakamisa ngokwawo. Ngenxa yokuthi amayunithi amaningi okusebenza okwakha awakunaki ngokwanele ukusebenza kwemishini yokuphakamisa, lokhu kuye kwabangela ukuntuleka kokunakekelwa nokuphathwa kwemishini yokuphakamisa. Ngaphezu kwalokho, inkinga yokwehluleka kwemishini yokuphakamisa yenzeke. Njengenkinga yokuvuza kwamafutha emshinini wokunciphisa, ukudlidliza noma umsindo kwenzeka ngesikhathi sokusetshenziswa. Ngokuhamba kwesikhathi, kuzoletha izingozi zokuphepha nakanjani. Isihluthulelo sale nkinga ukuthi umqhubi wokwakha akanakho ukunakwa okwanele ekuphakamiseni imishini futhi akazange asungule itafula lokuphakamisa eliphelele lokulungisa imishini.
Okwesibili, izingozi zokuphepha kanye nokukhubazeka kwemishini kagesi yokuphakamisa imishini. Izingxenye zikagesi ziyingxenye ebalulekile yezinto zikagesi. Kodwa-ke, okwamanje, izembozo eziningi zokuvikela zangempela ziye zanqamula izinkinga ngesikhathi sokwakhiwa kwemishini yokuphakamisa, ukuze izingxenye ze-elekthronikhi ziye zabhekana nokugqoka okunzima, okuye kwabangela uchungechunge lwezingozi zokuphepha.
Okwesithathu, izingozi zokuphepha kanye nokukhubazeka kwezingxenye eziyinhloko zemishini yokuphakamisa. Izingxenye eziyinhloko zemishini yokuphakamisa zihlukaniswe zibe izinhlobo ezintathu: enye i-hook, enye intambo yocingo, futhi ekugcineni i-pulley. Lezi zingxenye ezintathu zinomthelela obalulekile ekusebenzeni okuphephile nokuzinzile kwemishini yokuphakamisa. Umsebenzi oyinhloko wehuku ukulenga izinto ezinzima. Ngakho-ke, phakathi nesikhathi eside sokusetshenziswa, i-hook ijwayele kakhulu ukuphumula kokukhathala. Futhi uma ihhuku isisemahlombe ngenani elikhulu lezinto ezisindayo, kuzoba nenkinga enkulu yengozi yokuphepha. Intambo yocingo ingenye ingxenye yomshini wokuphakamisa ophakamisa izinto ezisindayo. Futhi ngenxa yokusetshenziswa isikhathi eside nokuguga, nakanjani kuzoba nenkinga yokuguquguquka, futhi izingozi zenzeke kalula endabeni yokulayisha ngokweqile. Okufanayo kuyiqiniso ngama-pulleys. Ngenxa yokushelela kwesikhathi eside, i-pulley izokwenzeka nakanjani emifantwini nasekulimaleni. Uma kwenzeka iphutha ngesikhathi sokwakha, izingozi ezinkulu zokuphepha zizokwenzeka nakanjani.
Okwesine, izinkinga ezikhona ekusetshenzisweni kwemishini yokuphakamisa. Umsebenzisi womshini ophakamisayo akajwayelene nolwazi oluhlobene nokusebenza kokuphepha kwe-crane. Ukusebenza okungalungile kwemishini yokuphakamisa kuzodala umonakalo omkhulu emishinini yokuphakamisa kanye nabaqhubi ngokwabo.
