Konke mayelana nojekhi bezimoto nezitendi
Okuqukethwe
Cishe wonke umuntu useshintshe isondo okungenani kanye empilweni yakhe. Nakuba isondo eliyisipele libhekwa njengesidingo, ithuluzi lesibili elibaluleke kakhulu lomsebenzi ujeke. Ngaphandle kwayo, akunakwenzeka ukuphakamisa imoto phansi.
Ojeke nojeke akuzona nje ezokushintsha amathayi. Bangakwazi futhi ukuguqula noma iyiphi indawo ibe ishabhu yezimoto ngokushesha, okuvumela abasebenzisi (noomakhenikha) ukuthi benze ukunakekelwa kwemoto kanye nokulungisa khona kanye endleleni yokungena.
Ojeke nezitendi kuphephe kakhulu futhi kuthembekile uma kusetshenziswe ngendlela efanele, kanti ujeke nesitendi kusetshenziswa ngokwesisindo semoto.
Incazelo yojeke nezitendi
AmaJacks
Ujeke wemoto usebenzisa amandla adonsa amanzi ukuze uphakamise ingxenye yemoto, unikeze umsebenzisi amandla okushintsha isondo noma ukulungisa noma ukulungisa. Amajack afika ngezinhlobo ezahlukene nezigaba zesisindo. Ukukhetha uhlobo olufanele lukajekhi ngomsebenzi osuwenzile akubalulekile nje kuphela ekuphepheni komakhenikha, kodwa nasemotweni.
Cishe yonke imoto entsha edayiswayo iphuma nojeke njengethuluzi elijwayelekile lokushintsha isondo. Nakuba lawa majekhi ekulungele ukuphakamisa imoto ngamasentimitha ambalwa ukusuka phansi ukuze ushintshe isondo, umsebenzi ojulile udinga ujeke wesibili noma izitendi zikajeke.
Kuhlale kuwukuhlakanipha ukuqaphela lapho usebenzisa ujeke. Uma imoto ezophakanyiswa inesisindo esingamathani ama-2, sebenzisa ujeke okalwe okungenani amathani angu-2.5. Ungalokothi usebenzise ujeke emotweni lapho umthamo wayo wokuphakamisa ungaphezu komthamo wayo olinganiselwe.
UJack Uyama
Izitendi zikajack zibumbeke njengombhoshongo noma i-tripod futhi zenzelwe ukusekela isisindo semoto ephakanyisiwe. Kufanele zibekwe ngaphansi kwe-ekseli noma uhlaka lwemoto ukuze zinikeze ukwesekwa okwengeziwe emotweni ephakanyisiwe.
Ngemuva kokuthi imoto iboshwe, izitendi ziyabekwa bese imoto yehliselwa kuzo. Izitendi zikajeke zineziqongo zezihlalo eziklanyelwe ukusekela i-asi yemoto. Izitendi kufanele zisetshenziswe kuphela ezindaweni eziqinile nezisezingeni futhi kuphela ezimotweni ezinesisindo esingaphansi komthamo wezitendi.
Izitendi zamaJack zitholakala ngezinhlobo ezahlukene futhi zihlukaniswa ngokuya ngobude bazo obukhulu nomthamo womthwalo. Ezimweni eziningi, ukuphakama kwe-jack kuvezwa ngamasentimitha, futhi umthamo wokuphakamisa uvezwa ngamathani.
Izitendi zikaJack zivame ukuthengiswa ngababili futhi zivame ukusetshenziswa namajekhi aphansi. Ubude besitendi ngokuvamile busukela kumayintshi angu-13 kuye kwangu-25, kodwa bungaba ngamafidi angu-6. Umthamo wokulayisha ungahluka kusuka kumathani ama-2 kuye kwamathani angama-25.
Izitendi zikaJack zisetshenziselwa kakhulu ukulungisa noma ukulungisa, ngokuvamile azisetshenziselwa ukushintsha isondo.
Izinhlobo ezihlukahlukene zojeke
UPaul Jack
Ujeke waphansi uwuhlobo olujwayeleke kakhulu lukajekhi olusetshenziselwa ukulungisa nokulungisa. Kulula ukuwahambisa futhi abeke endaweni efanele ukuphakanyiswa. Ujeke waphansi uqukethe iyunithi ekhwezwe kancane enamasondo amane nesibambo eside umsebenzisi asicindezelayo ukuze asebenzise ingxenye yejekhi ephakamisa amanzi. Isihlalo sikajeke yidiski eliyindilinga elixhumene nemoto.
Iphrofayili ephansi yeyunithi yenza kube lula ukuyilawula. Isibambo kufanele siphendulwe ngokwewashi ukuvala ivalvu ngaphambi kokucindezela isibambo ukuphakamisa ujeke. Isibambo siphendulwa ngokuphambene newashi ukuze uvule i-valve bese wehlisa isihlalo sikajeke.
Ojeke bangamahhashi omsebenzi womphakathi ontshontshayo futhi bawusizo kakhulu emisebenzini edinga umakhenikha ukungena ngaphansi kwemoto.
ujeke wesikele
Ujeke wesikele wuhlobo lukajeke abantu abaningi abanalo esiqwini semoto yabo. Isebenzisa i-screw mechanism ukwenza i-lift. Inzuzo eyinhloko yalolu hlobo lwejack ubukhulu bayo obuncane nokuphatheka.
Ujeke ubekwa ngaphansi kwendawo okumele iphakanyiswe futhi isikulufu siphendulwa ngesibambo ukuze siphakamise noma sehlise imoto. Ezimweni eziningi, isibambo sizoba i-pry bar eza nemoto.
Ezimweni eziningi, ujeke ohlinzekwa ngemoto uklanyelwe ukufakwa ezindaweni ezithile zokugqekeza imoto. Uma kudingeka enye indawo, qiniseka ukuthi ilingana nemoto futhi inomthamo ofanele wokulayisha.
I-Hydraulic Bottle Jack
Lo jeki omise okwebhodlela usebenzisa i-hydraulic pressure ukuphakamisa izimoto ezisindayo nezinye izinto zokusebenza ezinkulu. Lawa ojeke anamandla okuphakamisa aphezulu futhi kufanele asetshenziswe endaweni eqinile nesezingeni. I-lever iyafakwa futhi ifakwe umoya ukuze iphakamise imoto.
Nakuba ojeke bamabhodlela benomthamo omkhulu wokulayisha futhi baphatheka kahle, abanakho ukuhamba kukajeke waphansi futhi abaqinile ngokwanele ukuba basetshenziswe eceleni komgwaqo, okubenza babe ngaphansi kokulungele izinguquko zamasondo.
Njengabo bonke ojeke, hlola umthamo wejekhi yebhodlela ngesisindo semoto ngaphambi kokuwusebenzisa.
Hi-Lift Jack
Lona ujeke okhethekile osetshenziswa nezimoto eziphakeme noma ezingekho emgwaqeni. Lawa ojeke asetshenziswa kakhulu ezindaweni ezingekho emgwaqeni noma lapho izindawo ezimbi zikhawulela ukusetshenziswa kwezinye izinhlobo zojeke.
Ojeke be-Hi-Lift bavame ukuba nomthamo omkhulu olinganiselwa kumakhilogremu angu-7,000 futhi bangaphakamisa imoto ifike ezinyaweni ezinhlanu. Ngokuvamile zingamafidi angu-3 kuya kwangu-5 ubude futhi zingaba nesisindo esingafika kumakhilogremu angu-30, okuzenza zingakufanelekeli ukuthuthwa ngemoto evamile.
Izinhlobo ezihlukahlukene zojeke
Izinto zokuma
Izimo zikaJack azihlukani kakhulu, kodwa izinto ezenziwe ngazo zingenza umehluko omkhulu.
Ama-coasters amancane futhi alula ngokuvamile enziwe nge-aluminium noma insimbi elula. UJack umele izimoto ezisindayo kumele zenziwe ngensimbi noma ngensimbi.
ukuphakama okungashintshi
Lezi zitendi zinokuphakama okungaguquki, okuzinikeza inzuzo yokungabi nezingxenye ezihambayo ezingahluleka. Kodwa-ke, azikwazi ukulungiswa, ngakho aziguquguquki noma aziphatheki kahle kakhulu. Lawa ma-rack athembekile kakhulu futhi aqinile futhi uma esetshenziswa endaweni eyodwa kuphela ngemoto efanayo, ayisinqumo esihle kakhulu.
Ubude obulungisekayo
Izitendi zikajack ezilungisekayo zikuvumela ukuthi ulungise ubude. Uhlobo oluvame kakhulu yisitendi se-tripod esimaphakathi esinenotshi yokulungiswa kobude. Ubude bungalungiseka nge-ratchet efakiwe.
Izitendi ezilungisekayo ezisindayo ngokuvamile zisebenzisa iphinikhodi yensimbi engena emigodini ephakathi nendawo. Ama-coasters ekhwalithi ephezulu afika nephinikhodi yesibili yokuphepha.
Uhlobo lokugcina lwesitendi esingalungiseka ngobude lubizwa ngokuthi yi-swivel stand futhi umsebenzisi kufanele azungezisa indawo yokuma emaphakathi ngokwewashi ukuze aphakamise ubude nangokuphikisana newashi ukuze ehlise.
Amathiphu Okuphepha
Ojeke nezitendi kuphephe kakhulu uma kusetshenziswe ngendlela efanele, kodwa kukhona amathiphu ambalwa okuphepha okufanele uwalandele:
Bheka imanuwali yomnikazi ukuze uthole amaphuzu anconyiwe okuphakamisa kanye nokusekela emotweni.
Ijekhi kufanele isetshenziselwe kuphela ukuphakamisa imoto isuke phansi. Izitendi zikaJack kufanele zisetshenziselwe ukuyibamba endaweni.
Sebenzisa ojeke lapho usebenza ngaphansi kwemoto, ungalokothi ungene ngaphansi kwemoto esekelwa ujeke kuphela.
Vimba amasondo njalo ngaphambi kokuphakamisa imoto. Lokhu kuzoyigcina ingagingqiki. Izitini, amasondo amasondo noma amaweji okhuni azokwenza.
Ijekhi namajekhi kufanele kusetshenziswe kuphela endaweni esezingeni.
Imoto kumele ibe sepaki futhi kufakwe ibhuleki ngaphambi kokuba imoto iboshwe.
Nyakazisa imoto kancane ngenkathi iphezu kojeke ukuze uqiniseke ukuthi ivikelekile ngaphambi kokutshuza ngaphansi kwemoto.
