UJack kukukhanya okuqhelekileyo kunye nezixhobo ezincinci zokuphakamisa ezinoluhlu olubanzi lwezicelo.Ayisosona sixhobo sokuphakamisa kuphela esiyimfuneko ekugcinweni nasekulungisweni kwemoto, kodwa inoluhlu olubanzi lwezicelo kulwakhiwo, oololiwe, iibhulorho kunye nokuhlangulwa ngokukhawuleza.Ngophuhliso loqoqosho lwelizwe lam kunye noshishino lweemoto, iimoto ziye zangena ngokubanzi kwimizi yabantu abaqhelekileyo, kwaye imveliso yeemoto zabahambi iye yanda unyaka nonyaka.Ukwanda kwenani leemoto kwenze ukuba imfuno yeejack yande.
Itekhnoloji yeJack kwilizwe lethu yaqala kade.Malunga noo-1970, ngokuthe ngcembe sadibana nobuchwepheshe be-jack yangaphandle, kodwa inqanaba kunye nobuchwepheshe babavelisi basekhaya ngelo xesha lalingalingani kwaye lingenalo isicwangciso esimanyeneyo.Emva kwemijikelo emininzi yoyilo oludityanisiweyo lwesizwe, ukusekwa kwemigangatho yoshishino kunye nemigangatho yelizwe, ukumiselwa, ukulandelelana kunye nokwenziwa ngokubanzi kwemveliso yejack yasekhaya iphunyeziwe.Thatha ijekhi yehydraulic ethe nkqo njengomzekelo.Ngokwemigangatho yelizwe, iinxalenye eziqhelekileyo zenjongo ngokubanzi ziye zaveliswa ngokusesikweni, imveliso iye yanda, kwaye ixabiso lemveliso liye lancitshiswa.
Ngokusetyenziswa kweetekhnoloji ezifana nokuphakamisa ngokukhawuleza kunye nokubuya okucothayo kweoli, iimveliso zejack yelizwe lam ziphuculwe kakhulu ngokwamandla okuthwala, ubomi benkonzo, ukusebenza kokhuseleko, ulawulo lweendleko, njl., kwaye umgangatho wemveliso uye wasondela ngokuthe ngcembe kwaye wodlula uninzi. iimveliso zangaphandle ezifanayo.Iimveliso, kwaye uvule ngakumbi iimarike zaseYurophu nezaseMelika.
Okwangoku, uchungechunge lwe-jack ezithunyelwa ngaphandle lilizwe lethu ziphelele kwiindidi kunye neenkcukacha, kunye nokusebenza kwemveliso okuzinzileyo kunye nokhuphiswano oluqinileyo lwamazwe ngamazwe.
“Umgaqo wejekhi sisixhobo esikhaphukhaphu esikhaphukhaphu nesincinci esityhala izinto ezinzima ngaphakathi kwisibiyeli esingaphezulu okanye uzipho olusezantsi.Iindidi ezahlukeneyo zeejack zinemigaqo eyahlukileyo.Iijacks eziqhelekileyo ze-hydraulic zisebenzisa umthetho wePascal, kwaye oko kukuthi, uxinzelelo lolwelo luhambelana kuyo yonke into, ukuze ipiston igcinwe.I-screw jack isebenzisa i-reciprocating handle ukutyhala i-gap ye-ratchet ukuze ijikeleze, kwaye i-gear ijikeleza ukuphakamisa kunye nokunciphisa umkhono ukufezekisa umsebenzi wokuphakamisa kunye nokutsala amandla.
