Pamwamba CraneChotengera Chipangizo
Chipangizo chojambulira ndi chipangizo chomwe chimagwirizanitsa zinthu ndi crane kudzera pa mbedza. Gwiritsani ntchito mitundu yosiyanasiyana ya zida zojambulira kutengera mtundu, mawonekedwe, ndi kukula kwa chinthu choyimitsidwa. Zida zoyenera zimatha kuchepetsa kuchuluka kwa ogwira ntchito ndikuwongolera kwambiri magwiridwe antchito.

Nthawi zambiri, makina onyamulira amagwira ntchito yochotsa zinthu, kunyamula, ndi kutsitsa motsatizana, ndi njira zofananira zimagwira ntchito pafupipafupi. Makina onyamulira amagwiritsidwa ntchito makamaka posamalira zinthu zamtundu umodzi. Yokhala ndi zidebe zonyamula, imatha kunyamula zinthu zotayirira monga malasha, ore, ndi tirigu. Zokhala ndi zidebe, zimatha kukweza zinthu zamadzimadzi monga zitsulo. Makina ena onyamulira, monga ma elevator, amathanso kugwiritsidwa ntchito kunyamula anthu. Nthawi zina, zida zonyamulira ndiyenso makina ogwiritsira ntchito, monga kutsitsa ndi kutsitsa zida pamadoko ndi masiteshoni.
