Kusankhidwa kwa Jack kumatha kukhudza kwambiri chitetezo komanso kuchita bwino pokweza ndikuthandizira magalimoto. Mwa mitundu yosiyanasiyana ya ma jacks, ma jacks a chubu ndi ma jacks wamba amawonekera ngati zosankha zotchuka. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi kungakuthandizeni kupanga chisankho choyenera malinga ndi zosowa zanu zenizeni.
Kodi chubu jack ndi chiyani?
Ma tube Jacks, yomwe nthawi zambiri imatchedwa "majekete a ngolo" kapena "mabokosi apansi," amapangidwa ndi thupi lalitali la cylindrical lomwe limalola kuyenda mosavuta ndi kukweza. Ma chubu jacks nthawi zambiri amakhala ndi makina a hydraulic omwe amawalola kukweza zinthu zolemetsa mosavutikira. Mapangidwe awo nthawi zambiri amakhala ndi maziko okhazikika okhazikika komanso chogwirira chachitali chothandizira, kuwapangitsa kukhala oyenera kunyamula magalimoto mu garaja kapena malo ochitirako misonkhano.
Jack wachikhalidwe ndi chiyani?
Komabe, ma jacks achikhalidwe ndi achikhalidwe kwambiri pamapangidwe. Zitha kukhala zamakina kapena ma hydraulic, koma nthawi zambiri zimadziwika ndi zomangamanga zosavuta. Ma jacks awa nthawi zambiri amatenga mawonekedwe a scissor jack kapena jack botolo. Sikasi amagwiritsa ntchito makina opangira crank kukweza galimotoyo, pomwe jack ya botolo imagwiritsa ntchito ma hydraulic system koma nthawi zambiri imakhala yaying'ono komanso yosunthika.
Kusiyana kwakukulu
- Kukweza mphamvu: Ma chubu jacks nthawi zambiri amakhala ndi mphamvu yokweza kwambiri kuposa ma jacks achikhalidwe. Izi zimawapangitsa kukhala abwino kwa magalimoto akuluakulu omwe amafunikira chithandizo champhamvu, monga magalimoto ndi ma SUV. Ma Jack achikhalidwe, ngakhale amathandizira pamagalimoto ang'onoang'ono, amatha kulimbana ndi katundu wolemera.
- Zosavuta kugwiritsa ntchito: The chubu jack idapangidwa kuti ikhale yosavuta kugwiritsa ntchito, kulola wogwiritsa ntchito kukweza galimotoyo mwachangu ndi mphamvu zochepa zolimbitsa thupi. Makina opangira ma hydraulic amapereka njira yokweza bwino, ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito, makamaka kwa iwo omwe mwina alibe zambiri zamakina. Ma jacks achikhalidwe, makamaka ma scissor jacks, angafunike kulimbikira komanso nthawi yogwira ntchito.
- Kukhazikika: Maziko ambiri a chubu jack amawonjezera kukhazikika ndikuchepetsa chiwopsezo chakuyenda kapena kutsetsereka pokweza galimoto. Izi ndizofunikira makamaka pogwira ntchito pansi pagalimoto, pomwe chitetezo ndichofunika kwambiri. Ma jacks achikhalidwe, makamaka ang'onoang'ono, sangapereke mlingo womwewo wa kukhazikika, zomwe zingakhale zodetsa nkhawa kwa ogwiritsa ntchito.
- Kunyamula: Ma Jack achikhalidwe, makamaka ma scissor Jacks ndi ma jacks a mabotolo, nthawi zambiri amakhala ophatikizika komanso opepuka, zomwe zimapangitsa kuti zikhale zosavuta kusunga ndi kunyamula. Ma tube jacks, akadali osunthika, amatha kukhala ochulukirapo chifukwa cha kapangidwe kake ndi zida zama hydraulic. Ngati mukufuna jack pakagwa mwadzidzidzi pamsewu, jack yachikhalidwe ikhoza kukhala yabwino.
- Mtengo: Nthawi zambiri, ma jacks a chubu amakhala okwera mtengo kuposa ma jacks achikhalidwe chifukwa cha makina awo apamwamba kwambiri a hydraulic komanso kuthekera kokweza kwambiri. Ngati bajeti ndiyodetsa nkhawa, ma jacks azikhalidwe amatha kupereka njira yotsika mtengo, makamaka kwa ogwiritsa ntchito wamba omwe amafunikira jack nthawi zina.
Pomaliza
Mwachidule, kusankha pakati pa achubu jackndipo jack yachikhalidwe zimatengera zosowa zanu komanso momwe zinthu zilili. Ngati nthawi zambiri mumagwira ntchito pamagalimoto akuluakulu kapena mukufuna jack yosavuta kugwiritsa ntchito komanso yokhazikika, jack chubu ikhoza kukhala yabwinoko. Komabe, ngati kusuntha ndi mtengo ndizolinga zanu zazikulu, jack yachikhalidwe imatha kukuthandizani bwino. Pamapeto pake, kumvetsetsa zabwino ndi zoyipa zamtundu uliwonse kudzakuthandizani kusankha bwino pazosowa zanu zokweza.
