Kuyambira kubadwa kwa makina opangira chipika, dzikolo lapereka chidwi kwambiri pakukula kwa nyumba yobiriwira. Pakali pano, ndi gawo lokha la nyumba za m'mizinda ikuluikulu zomwe zingathe kukwaniritsa miyezo ya dziko. Zomwe zili pachimake panyumba yobiriwira ndizomwe zingagwiritsidwe ntchito kupulumutsa mtengo wa nyumbayo. Kumbali ina, tingateteze bwanji chilengedwe, ndikuzindikira chitukuko chenicheni cha chuma ndi chilengedwe pamodzi Chitukuko chokhazikika. Makina opangira chipika wokha ndi mtundu wa makina omwe amatha kuzindikira kugwiritsanso ntchito zinthu ndikupulumutsa mphamvu. Ndi mtundu watsopano wamakina a njerwa ku China. Lili ndi makhalidwe ambiri omwe makina a njerwa zadongo alibe. Makina opangira njerwa apangidwa kuchokera ku makina oyambira njerwa kupita kumitundu yosiyanasiyana yamakina a njerwa monga makina opangira njerwa, makina a njerwa za simenti, makina a njerwa opanda kanthu, ndi zina zambiri. Makina atsopano opangira njerwa ali ndi mawonekedwe ophatikizika, mphamvu yayikulu yolimbikitsira, kulimba kwamphamvu ndi ntchito yosavuta Single, kutulutsa kwakukulu, kulimba ndi zina, kusintha kwa liwiro la makina osinthira, kuzungulira kwa disk ndi magawo ena ogwiritsira ntchito, kuwongolera kwamphamvu, kutsika kwamphamvu kwamphamvu, kutsika kwamphamvu kwapang'onopang'ono. Malinga ndi zofunikira za nyumba zamakono, makina opangira chipika amatha kupulumutsa mphamvu. Nyumba yomangidwa ndi zida zatsopano zamakhoma imatha kupulumutsa pafupifupi 32 zida. Kunja kwa nyumbayo kumalimbikitsidwa ndi mfundo yomanga botolo losungira kutentha. Ukadaulo wosungika bwino wosunga kutentha ndi kusungunula umatengedwa kuti upange gawo lotchingira kutentha kuchokera mkati kupita kunja ndi njira zolekanitsa ndi zomangira, zomwe zingathandize kwambiri kuteteza mphamvu. Makina a njerwa amasiku ano akwanitsa kupulumutsa mphamvu zomanga ndikuwongolera chilengedwe, zomwe zikuwonetsa kuti zida zamakina anjerwa ku China zikukula pang'onopang'ono.
