UJack ungukukhanya okuvamile kanye nemishini encane yokuphakamisa enezinhlobonhlobo zezinhlelo zokusebenza.Akulona kuphela ithuluzi eliyinhloko lokuphakamisa elidingekayo ekunakekeleni nasekulungiseni imoto, kodwa futhi linenhlobonhlobo yezinhlelo zokusebenza zokwakha, izitimela, amabhuloho, nokuhlenga izimo eziphuthumayo.Ngokuthuthuka komnotho wezwe lami kanye nemboni yezimoto, izimoto sezingene emakhaya abantu abajwayelekile, kanti nokukhiqizwa kwezimoto zabagibeli kuye kwanda unyaka nonyaka.Ukwenyuka kwesibalo sezimoto kwenze kwanda isidingo sojeke.
Ubuchwepheshe beJack ezweni lakithi buqale sekwephuzile.Ngawo-1970, kancane kancane sahlangana nobuchwepheshe bamajekhi angaphandle, kodwa izinga nobuchwepheshe babakhiqizi basekhaya ngaleso sikhathi kwakungalingani futhi kungenalo uhlelo oluhlangene.Ngemuva kwemizuliswano eminingana yomklamo ohlanganyelwe kazwelonke, ukusungulwa kwamazinga embonini kanye namazinga kazwelonke, ukumisa, ukukhiqizwa kwe-serialization kanye nokukhiqizwa okujwayelekile kokukhiqizwa kwamajack ekhaya sekuqaliwe.Thatha ujeke we-hydraulic omile njengesibonelo.Ngokuvumelana nezindinganiso zikazwelonke, izingxenye ezivamile zenjongo evamile ngokuyisisekelo zakhiqizwa ngokomsebenzi, okukhiphayo kuye kwanda, futhi izindleko zomkhiqizo zincishisiwe.
Ngokusetshenziswa kobuchwepheshe obunjengokuphakamisa ngokushesha kanye nokubuya kukawoyela kancane, imikhiqizo kajeke yezwe lami ithuthukiswe kakhulu ngokwamandla okuthwala, impilo yesevisi, ukusebenza kokuphepha, ukulawula izindleko, njll., futhi ikhwalithi yomkhiqizo iye yasondela kancane kancane futhi yedlula iningi. imikhiqizo yangaphandle efanayo.Imikhiqizo, futhi uvule izimakethe zaseYurophu nezaseMelika.
Njengamanje, uchungechunge lwamajack oluthunyelwa ezweni lethu luphelele ngezigaba nokucaciswa, nokusebenza komkhiqizo okuzinzile kanye nokuncintisana okuqinile kwamanye amazwe.
“Isimiso sikajeke ithuluzi lokuphakamisa elilula nelincane eliphusha izinto ezisindayo phakathi kwe-stroke encane yabakaki abangaphezulu noma uzipho olungezansi.Izinhlobo ezahlukene zojeke zinezimiso ezahlukene.Ama-jacks ajwayelekile we-hydraulic asebenzisa umthetho kaPascal, futhi Okusho ukuthi, ukucindezela koketshezi kuyavumelana kulo lonke, ukuze i-piston igcinwe inganyakazi.I-screw jack isebenzisa isibambo esiphindaphindayo ukuze iphushe igebe le-ratchet ukuze lizungezise, ​​futhi igiya liyazungeza ukuze liphakamise futhi lihlise umkhono ukuze kuzuzwe umsebenzi wokuphakamisa nokudonsa amandla.
