Chifukwa chakukula kwa msika wazinthu zamapulasitiki, kukweza kwa zida zamakina omangira jekeseni kukukulanso mwachangu.Makina omangira jekeseni oyambilira onse anali a hydraulic, ndipo m'zaka zaposachedwa pakhala pali makina omangira jekeseni olondola kwambiri amagetsi.
China italowa m'bungwe la World Trade Organisation (WTO), makampani opanga makina akunja adapititsa patsogolo kusamutsidwa kwawo ku China.Makampani ena odziwika bwino opangira jekeseni padziko lonse lapansi, monga Germany Demark, Krupp, Badenfeld, ndi Sumitomo Heavy Industries, adakhazikika motsatizana ku "China, ena akhazikitsanso malo aukadaulo.Kulowa kwa opanga makina opangira jekeseni akunja kwabweretsa nyonga kumakampani opanga makina ojambulira aku China, ndipo nthawi yomweyo, kwadzaza mwayi ndi zovuta kwa opanga makina opangira jakisoni aku China.
Pakadali pano, makina opangira jakisoni aku China amakhala makamaka pazida zazing'ono komanso zapakatikati.M'zaka za m'ma 1980 ndi 1990, kuperekedwa kwa zinthu zotsika kunaposa zomwe zinkafunidwa, mphamvu zopangira zidali zambiri, ndipo mphamvu za kampaniyo zidatsika.Mitundu ina, makamaka yamtengo wapatali kwambiri, imakhalabe yopanda kanthu ndipo iyenera kutumizidwa kunja.Malinga ndi ziwerengero mchaka cha 2001, China idatengera makina opangira jekeseni omwe amagwiritsa ntchito ndalama zakunja zokwana madola 1.12 biliyoni aku US, pomwe makina opangira jekeseni otumiza kunja adangopeza ndalama zokwana madola 130 miliyoni aku US, ndipo zogulitsa kunja ndizokulirapo kuposa zotumiza kunja.
Makina opangira ma jakisoni amtundu wa hydraulic ali ndi zabwino zambiri zapadera pakumangirira bwino komanso mawonekedwe ovuta.Zasintha kuchokera kumtundu wamtundu umodzi wamadzimadzi odzaza madzi ndi ma cylinder ambiri kupita kumtundu wapampando wapawiri wapawiri, momwe mbale ziwiri zimapanikizidwa mwachindunji.Woyimilira kwambiri, koma ukadaulo wowongolera ndizovuta, kulondola kwa makina ndikokwera, ndipo ukadaulo wa hydraulic ndizovuta kudziwa.
Makina opangira jekeseni wamagetsi onse ali ndi maubwino angapo, makamaka pankhani yachitetezo cha chilengedwe komanso kupulumutsa mphamvu.Chifukwa cha kulondola kwamphamvu kwa jekeseni wa servo motor, kuthamanga kwa kuzungulira kumakhalanso kokhazikika, ndipo kumatha kusinthidwa magawo angapo.Komabe, makina opangira jekeseni wamagetsi onse sakhala olimba ngati makina opangira jekeseni wa hydraulic, pamene makina opangira jekeseni wa hydraulic full-hydraulic ayenera kugwiritsa ntchito ma valve a servo omwe ali ndi mphamvu zotsekedwa kuti atsimikizire kulondola, ndipo ma valve a servo ndi okwera mtengo komanso okwera mtengo.
Makina opangira jakisoni amagetsi-hydraulic ndi makina atsopano opangira jakisoni ophatikiza ma hydraulic ndi magetsi.Zimaphatikiza zabwino zogwira ntchito kwambiri komanso zopulumutsa mphamvu zamagetsi zonse zamakina opangira jekeseni wa hydraulic.Makina opangira jekeseni amagetsi-hydraulic awa Akhala njira yopangira ukadaulo wamakina opangira jakisoni.Makampani opangira jekeseni akukumana ndi mwayi wofulumira.Komabe, pamtengo wazinthu zopangira jekeseni, mtengo wamagetsi umakhala wokwera kwambiri.Malinga ndi zomwe zimafunikira pakupangira zida zamakina opangira jakisoni, jekeseni wamafuta pampu yamoto amagwiritsa ntchito gawo lalikulu la zida zonse zomwe zimagwiritsidwa ntchito.50% -65%, kotero ili ndi kuthekera kwakukulu kopulumutsa mphamvu.Kupanga ndi kupanga mbadwo watsopano wa makina opangira jekeseni "wopulumutsa mphamvu" wakhala kufunikira kofulumira kumvetsera ndi kuthetsa mavuto.
