Makina opangira njerwa a Hercules, ukadaulo womwe umagwiritsidwa ntchito pazida izi ndiukadaulo wotsogola ku China. Zomwe zidadziwika bwino pazidazi ndizomwe zimapangidwira komanso zowoneka bwino. Zinyalala zomanga ndi zida zina zopangira zinyalala zolimba kuti zikwaniritse zokha zokha, kudyetsa basi, kuphwanya ndi kuwunika kodziwikiratu kupanga koyimitsa kamodzi; Chida chopangira malo ochezeka komanso chodziwikiratu chimazindikira kugwedezeka kolowera, ndipo ma brake osinthika pafupipafupi amatha kuthetseratu kugwiritsa ntchito mphamvu popanda kugawa kwamanja, zomwe zimachepetsa kwambiri kuchuluka kwa ntchito. Kupanikizika mmwamba ndi pansi, kugwedezeka kwamphamvu, makamaka koyenera kupanga midadada yamphamvu kwambiri, yomwe imatha kuikidwa pambuyo popanga.

Makina amodzi ali ndi zolinga zambiri ndipo amatha kupanga midadada yamitundu yosiyanasiyana yokhala ndi nkhungu zosiyanasiyana. Thupi la makinawo limapangidwa ndi kuponyedwa kwapamwamba kwambiri komanso mwamphamvu kwambiri komanso ukadaulo wapadera wowotcherera ndi zida, zolimba bwino, kukana kugwedezeka, moyo wautali wautumiki, kapangidwe kake ka katundu wapamwamba, kuchitapo kanthu koyengedwa, kutsekedwa mokakamiza komanso phokoso lochepa. Makinawa amatengera njira zoyendetsera zokakamiza, zomwe zimapangitsa makinawo kukhala ndi mawonekedwe ogwiritsira ntchito zida zambiri, kugawa mwachangu komanso kofananira, zokolola zambiri komanso kutsogolera ntchito zoteteza zachilengedwe pakati pamitundu yakunyumba. Ukadaulo wa kuphatikiza kwamakina, magetsi ndi ma hydraulic amatengedwa kuti apangitse njira iliyonse yoyendetsera zida kuti ikhale yogwirizana, kotero kukhazikika kwa zinthu zopangidwa ndipamwamba komanso kutsika kwamitengo kumakhala kochepa. Makina amodzi ali ndi zolinga zambiri. Posintha nkhungu, imatha kupanga zinthu za simenti monga njerwa za porous, chipika chopanda kanthu, kerb, njerwa zapanjira, njerwa zamtengo wa udzu, njerwa zoteteza malo otsetsereka ndi zina zotero. Ndi chipangizo cha nsalu, imatha kupanga utoto wamsewu wamtundu ndi zinthu zina.
