Ma cranes a pansi ndi zida zazing'ono zogwirira ntchito zonyamulira kapena kunyamula katundu. Nthawi zambiri, mphamvu zonyamulira zimakhala kuyambira 300kg mpaka 500kg. Khalidwe lalikulu ndilakuti mphamvu zake zonyamulira zimakhala zosinthasintha, zomwe zikutanthauza kuti pamene mkono wa telescopic ukukwera ndikukwera, mphamvu zonyamulira zimachepa. Mkono wa telescopic ukabwezedwa, mphamvu zonyamulira zimatha kufika pafupifupi 1200kg, zomwe zimapangitsa kuti zikhale zoyenera ntchito zosavuta zonyamulira katundu, zomwe zimapulumutsa ntchito komanso zosavuta. Pamene kutalika kukukwera, mphamvu zonyamulira zimatha kuchepa kufika 800kg, 500kg, ndi zina zotero. Chifukwa chake, ma cranes amagetsi onyamulika ndi oyenera kwambiri kugwiritsidwa ntchito m'ma workshop. Kulemera kwa zida zamagalimoto sikolemera kwambiri, koma n'kovuta kuti anthu azinyamule pamanja. Mothandizidwa ndi crane yaying'ono, zida zolemera monga injini zimatha kunyamulidwa mosavuta.

Ponena za mitundu yopangira yomwe ilipo pano, tili ndi mitundu 6 yokhazikika, yogawidwa malinga ndi kapangidwe ka zida zosiyanasiyana. Pa crane yathu yoyenda ya hydraulic, mtengo wake umakhala pakati pa USD 5000 ndi USD 10000, kusiyanasiyana malinga ndi mphamvu yonyamula katundu yomwe kasitomala amafunikira komanso kapangidwe ka zida. Ponena za kapangidwe konyamula katundu, katundu wokwera kwambiri nthawi zambiri amakhala matani awiri, koma apa ndi pamene mkono wa telescopic uli m'malo obwerera m'mbuyo. Chifukwa chake, ngati mukufuna crane yaying'ono yosinthasintha komanso yosavuta, mutha kuganizira crane yathu yaying'ono yogulitsira pansi.
