Jack ni urumuri rusanzwe nibikoresho bito byo guterura hamwe nurwego runini rwa porogaramu.Ntabwo ari igikoresho nyamukuru cyo guterura gusa ningirakamaro mu gufata neza imodoka no kuyisana, ariko kandi ifite uburyo butandukanye bwo kubaka, gari ya moshi, ibiraro, no gutabara byihutirwa.Iterambere ry’ubukungu bw’igihugu cyanjye n’inganda z’imodoka, muri rusange imodoka zinjiye mu ngo z’abantu basanzwe, kandi umusaruro w’imodoka zitwara abagenzi wiyongereye uko umwaka utashye.Ubwiyongere bwimibare yimodoka bwatumye ibyifuzo bya jack byiyongera.
Tekinoroji ya Jack mugihugu cyacu yatangiye itinze.Ahagana mu myaka ya za 70, twagiye buhoro buhoro duhura n’ikoranabuhanga rya jack ry’amahanga, ariko urwego n’ikoranabuhanga by’abakora mu gihugu icyo gihe ntibyari bihwanye kandi nta gahunda ihuriweho.Nyuma yuburyo butandukanye bwo guhuriza hamwe igihugu, gushyiraho amahame yinganda n’ibipimo by’igihugu, gushyira mu bikorwa, gutondekanya no kumenyekanisha umusaruro wa jack wo mu gihugu byashyizwe mu bikorwa.Fata urugero rwa hydraulic jack nkurugero.Ukurikije ibipimo byigihugu, ibice rusange-bigamije rusange byakozwe muburyo bwumwuga, umusaruro wagiye wiyongera, nigiciro cyibicuruzwa cyaragabanutse.
Hamwe nogukoresha tekinoloji nko guterura vuba no gutinda kwa peteroli gahoro, ibicuruzwa bya jack byigihugu cyanjye byateye imbere cyane mubijyanye no gutwara imbaraga, ubuzima bwa serivisi, imikorere yumutekano, kugenzura ibiciro, nibindi, kandi ubwiza bwibicuruzwa bwagiye bwegera buhoro buhoro burenga benshi. ibicuruzwa bisa n’amahanga.Ibicuruzwa, no kurushaho gufungura amasoko yu Burayi na Amerika.
Kugeza ubu, urutonde rwa jack rwoherejwe n’igihugu cyacu rwuzuye mu byiciro no mu bisobanuro, hamwe n’ibicuruzwa bihamye kandi bihanganye ku rwego mpuzamahanga.
Ati: “Ihame rya jack nigikoresho cyoroheje kandi gito cyo guterura gisunika ibintu biremereye mumutwe muto wumutwe wo hejuru cyangwa ku nsi yo hepfo.Ubwoko butandukanye bwa jack bufite amahame atandukanye.Amazi ya hydraulic asanzwe akoresha amategeko ya Pascal, kandi ni ukuvuga ko umuvuduko wamazi uhoraho mugihe cyose, kugirango piston ikomeze kuguma.Jack ya screw ikoresha ikiganza cyo kwisubiraho kugirango isunike icyuho cya ratchet kuzunguruka, kandi ibikoresho bizunguruka kugirango bizamure kandi bimanure amaboko kugirango bigere kumurimo wo guterura no gukurura imbaraga.
