• yakaderera-kukwira kureba uye yakakura zvakakwana yakakura yekusimudza kureba inoita mudziyo wakadaro wakakodzera kune akawanda emota modhi;
• mutengo wakaderera.

Iyo jack-yakaita sedhaimani ine zvakare yakaringana yakashata:

• zvishoma kutakura mutoro;
• nzvimbo diki yerutsigiro uye, semhedzisiro, isiri yakanaka kugadzikana, saka zviri nani kuwedzera inshuwarisi mutoro wakasimudzwa nemaprops;
• haisi nyore kwazvo screw rotation mechanism;
• kudiwa kwekugara uchichenesa nekuzora.

Pakutengesa kune zvakare akareruka uye compact lever-screw zvishandiso.



Jacks dzakadaro dzakachipa zvikuru, asi zviri nani kurega kuzvitenga, nokuti vane matambudziko makuru nekugadzikana, kunyanya pavhu risina kuenzana. Kudonha kwemotokari hakuzomuiti zvakanaka, asi chinhu chikuru ndechekukuvadza kwakakomba kumunhu.

, inozivikanwawo sehijack (yakakwirira-jack) kana yakakwirira-inosimudza (yakakwirira-kusimudza), inosiyaniswa nehupamhi hwepikicha yakaderera, kukwirira kukuru kwekusimudzira - kusvika kune imwe nehafu yemamita - uye nyore kudzora. Iyo yekusimudza chikuva iri muchikamu chepamusoro chenjanji, ine huwandu hwemakomba e latch pamwe nehurefu hwayo hwose. Kufambisa njanji nepuratifomu kunoitwa uchishandisa lever. Iyo yekukwira uye yekudzika modhi inochinjirwa nekupuruzira yekukiya lever.

Kune zvakare rack uye pinion mhando jacks. Vanoshandisa giya rehonye rine ratchet, uye rinofambiswa nekutenderera kwemubato.



Hijack ine saizi yakakura uye uremu. Midziyo yakadaro inonyanya kufarirwa pakati pevaridzi veSUVs, pamwe neavo vanoshandisa michina yekurima. Rack jack inobatsira kudhonza nzira yakafanana kubva mumatope. Uye kune varidzi vemotokari dzakajairwa, iyi haisi sarudzo yakanaka.

Rack uye pinion jack inoda hwaro hwakasimba. Kana zvisina kudaro, zvinodikanwa kutsiva nzvimbo yakakosha, kana zvisina kudaro chitsitsinho chejack chichanyura muvhu rakapfava. Inofanira kuiswa zvakasimba, uye kukwira uye kudzika kunofanira kuitwa zvakanaka, kuve nechokwadi kuti hapana kukanganisa.

Rack jack haisi nzvimbo yakagadzikana nekuti ine diki tsoka. Nokudaro, mutoro wakasimudzwa unofanira kuchengetedzwa, somuenzaniso, negigi kana zvidhinha. Uye pasina mhaka usakwira pasi pemotokari! Pamhando dzose dzejeki, rack uye pinion ndiyo inonyanya kushungurudza.

Hijack haikurudzirwi kuti iomerwe, sezvo tsvina inonamatira kumafuta, izvo zvinogona kuita kuti michina iite jam.

inoshanda hydraulically. Iyo pombi yekutyaira inogadzira kudzvanywa kwemafuta muhumburumbira inoshanda, iyo inoshanda pane plunger, inosundira tsvimbo kumusoro. Tsvimbo ine chikuva chakakosha muchikamu chepamusoro chinotsikirira pamutoro, uchiusimudza. Kuvapo kwevhavha kunodzivirira mafuta kubva pakuyerera kumashure. Kuti udzivirire jack kubva pakukanganisa mukugadzira, pane kazhinji kune imwezve bypass valve inovhura kana mutoro unobvumirwa ukapfuura.

Pamusoro petsvimbo imwe chete, kune akawanda telescopic modhi ane maviri, uye dzimwe nguva ane matanda matatu anowedzera imwe kubva kune imwe sezvikamu zve telescopic antenna. Izvi zvinokutendera kuti uwedzere kureba kwekusimudza kusvika kusvika 400…500 mm. Varidzi vemotokari dzine nzvimbo yakakwirira yemvumo vanofanira kuteerera, somuenzaniso, kune 6-ton rori.

Kureba kwepikicha yemidziyo yakadaro kunotanga kubva 90 mm (somuenzaniso, modhi), uye simba rekutakura rinogona kusvika matani makumi mashanu kana kupfuura.

Mabhodhoro jacks ane akawanda mabhenefiti akaita kuti ashandiswe zvakanyanya. Pakati pavo:

• kukwirira kwakakura kwekutakura;
• kumhanya zvakanaka;
• kumisa urefu hwakarurama;
• autofix;
• mari shoma yebasa;
• diki diki uye uremu zvinokubvumira kuti utakure muhunde.

Izvo zvakanyanya zvisingabatsiri ndezvidiki zvekusimudza kureba, kuderera kwekukurumidza, matambudziko nekudzikisa kureba kwekururama.

Kuchengetedza uye kutakura kwe hydraulic jacks kunofanirwa kuitwa chete munzvimbo yakatwasuka kudzivirira kubuda kwemvura inoshanda.

inoshandawo kune hydraulic lifting devices. Nheyo yekushanda kwayo haina kunyanya kusiyana nebhodhoro. Mubhadharo wakafanana. Kureba kwepikicha kunonyanya 130 ... 140 mm, asi dzimwe nguva isingasviki 90 mm. Kusimudza kureba 300…500 mm.

Ese mabhenefiti emabhodhoro jacks, akanyorwa pamusoro, akajairwa ekutenderedza hydraulic lifts. Kunze kwezviyero uye uremu. Midziyo yekutenderedza, ine zvisingawanzo siyana, yakakurisa uye inorema kutakurwa zvachose mumotokari inotakura vanhu.

Zvimwe zvakanakira zvemhando iyi yejeki zvinosanganisira kugadzikana kwakanyanya, kunaka, kuchengeteka uye nyore kushandisa. Iyo rolling lift ine chikuva chine mavhiri, nekuda kweiyo inotyaira pasi payo mukusimudza mutoro. Panguva imwecheteyo, kusiyana nemamwe marudzi ose ejeki, kutsauka kwechigadzirwa kubva kune vertical hakubatanidzwi.

Zvisinei, kushandiswa kwemajeko ekukungurusa kunoda nhanho uye nzvimbo yakasimba isina matombo uye zvimwe zvinhu zvekunze. Iwo akanakira zvitoro zvematai uye maworkshop. Kune yega garaji, zvine musoro kutenga mudziyo wakadaro kana iwe kazhinji uchifanirwa kushandura mavhiri (iwe pachako, hama, shamwari) kana kuita kumwe kugadzirisa. Kana jack ichishandiswa nguva nenguva, zviri nani kutenga bhodhoro rakachipa kana jack yedhaimani.

Izvo zvinodikanwawo kufunga nezvehukuru hwegaraji, bhokisi rakamanikana rinogona kunge rakanyanya kutetepa kuti risimudze. Nezvemamiriro ezvinhu akadaro, iwe unofanirwa kusarudza modhi neruwoko runotenderera kuitira kuti ishande yakaenzana nemota uye madziro. Imwezve nyore inogona kunge iri tsoka pedal, iyo inomhanyisa nzira yekusimudza mutoro.

chokwadi, iyo inflatable pillow yakagadzirwa nepamusoro-simba polymer zvinhu, iyo inoiswa pasi pemuviri wemotokari. Iyo hose yakabatana nepombi yekupedza, uye magasi emhepo anozadza mhepo jack chamber, iyo inoputika uye inosimudza motokari. Kuvepo kwevharuvhu yecheki hakusanganisi kuvhuvhuta zvisina tsarukano kubva papiro. Iwe unogona zvakare kuzadza kamuri necompressor kana silinda yemhepo yakamanikidzwa. Kuti udzikise kudzvinyirira, kune vharafu inovhura nekudzvanya yakakosha lever.

Kuzadza kunoitika nekukurumidza, uye kushanda nesimba hazvidiwi, saka vakadzi vanozokoshesa jack iyi.

Chitsiko chakakura chinobvumira kushandiswa kwejeki yemhepo kudhonza muchina kubva mumadhaka, chando kana jecha. Iyo diki pikicha kureba - inenge 150 mm - inoita kuti zvikwanise kushandisa mudziyo wemotokari dzine pasi pevhu.

Mazhinji emhando dzepneumatic jacks akashongedzerwa nechigadzirwa chinotenderedza chine mavhiri, icho, chekutanga, chinowedzera kukwirira kwepikicha, uye chechipiri, haina kunyatsoita muchando kana jecha. Izvi zvinofanira kufungwa nezvazvo pakusarudza imwe muenzaniso.

Izvo zvakakoshawo kutarisisa kuvepo kweakakosha grooves pachikuva chekusimudza chejack, icho chinodzivirira muchina kubva pakutsvedza panguva yekusimudza kana kudzikisa. iyo inofanirwawo kuva nesimbi yesimbi pasi pepiro kubva pasi, izvi zvichawedzera kugadzikana kwese kwechimiro.

Upenyu hwebasa rejaki yepneumatic inotarirwa kunyanya nenguva yekukwegura kwezvinhu zvekamuri, saka hutano hwayo hunofanira kupiwa kunyanya.

Izvo zvisingabatsiri zvinosanganisira kusanyanya kugadzikana uye kuoma kwekuchengetedza kukwirira kwakagadziriswa kwekusimudza mutoro, sezvo nekuda kwekumanikidzwa kwegasi, kudzvinyirira munzvimbo dzakasiyana dzekamuri kunogona kusiyana. Pane zvakare njodzi yekuti kamera ichakuvadzwa nezvinhu zvakapinza panguva yekushandisa kana kuchengetedza.

Asi, pamwe, iyo huru drawback yerudzi urwu rwechigadzirwa mutengo wakakwira, ndosaka vazhinji vachizosarudza zvakachipa sarudzo.

Kana motokari iine pombi mbiri dzekupedza, airbag haizoputi. Iwe unozofanirwa kushandisa dzimwe nzira dzekupomba.

Iwe unogona kusarudza jack zvinoenderana neyakasiyana maitiro, asi matatu makuru ehunyanzvi paramita akakosha, ayo anogara achiratidzwa pane muviri uye kurongedza kwejack. Aya ndiwo masimba ekutakura, kureba kwepikicha (hook) uye kureba kwekusimudza.

1. Huremu hwekutakura ndiyo huremu hwepamusoro iyo jack yakagadzirirwa kusimudza pasina njodzi yekuremara. Kazhinji inotaurwa mumatani. Izvo zvinofanirwa kutakurwa mupfungwa kuti huwandu hwese hwemotokari mushure mekunge yavharwa inogoverwa pamusoro pemavhiri matatu uye jack. Kuti uve nemuganhu wekuchengeteka, zviri nani kusarudza chigadziro chinogona kumira zvishoma nehafu yehuremu hwemotokari yakatakura. Kuwedzeresa mutoro wemutoro hauzokanganisa kushanda, asi mutengo unogona kunge wakakwira. Iwe haufanirwe kutakurwa nekuchengetedza zvakare - zvishandiso zvakadaro hazvifanirwe kushandirwa pamuganho wekugona kwavo.
   
   Kurema kwepasipoti yemotokari haawanzopfuura tani nehafu, maSUV anogona kuyera 2 ... 3 matani.
2. Pickup urefu. Iyi ndiyo idiki inogoneka chinhambwe pakati pechigadziko kubva pazasi uye jack rutsigiro chikuva kubva kumusoro. Iyi parameter inosarudza kana zvichizogoneka kutsvedza jack pasi peimwe mota ine imwe clearance. Muchiitiko ichi, zvakakosha kufunga nezvemamiriro ezvinhu anogoneka nevhiri rakaputika, apo nzvimbo chaiyo yepasi pasi pasi pepasipoti. Nyatsorega mhepo ibude kunze kwetai uye kuyera mhedzisiro inobuda - kureba kwejeki kunofanirwa kukwana mune yakawanikwa kukosha. Yakawandisa stock haina basa pano, sezvo iyi parameter ine hukama nehupamhi hwekusimudza hurefu hunofanirwa kukwana kuti vhiri ribude pasi.
   
   Kana iwe uine mota ine yakaderera pasi clearance, iwe unofanirwa kubhadhara kune iyo inonzi. hook models. Vane pikicha yakakwirira ye20 ... 40 mm.
3. Iyo yakanyanya kusimudza kureba chinhambwe kubva pajacking point iyo mota inogona kusimudzwa. Inofanira kukwana kurembera vhiri.
4. Kurema uye zviyero. Izvo zvakakosha kune chigadziri chichagara chiri mumotokari.
5. Simba rinodiwa kuiswa kune lever kana mubato wekushanda. Mune mamwe mazwi, ingani iwe uchafanira kudikitira kuti usimudze mutoro.
6. Kuvapo kwerubha gasket kunodiwa kana muchina usina nzvimbo dzakakosha dzekuisa kusimudza.

Watenga jack, usamhanye kuiisa muhunde. Zviri nani kuti uiedze ipapo uye uve nechokwadi chekuti inoshanda, yakavimbika uye haizokuregi iwe kana paine chinodiwa chekushandisa kwayo.
