Waukulu mbali ya20 matani pamwamba pa cranendi mphamvu yake yonyamula katundu, yomwe imatha kunyamula matani 20, komanso imakhala yokhazikika komanso yotetezeka. Ili ndi mawonekedwe osavuta komanso osavuta kugwiritsa ntchito, ndipo imatha kuyendetsedwa ndi remote control kapena pamanja. Kuphatikiza apo, imakhala ndi mphamvu zambiri komanso kusinthasintha ndipo imatha kugwira ntchito m'malo osiyanasiyana ogwira ntchito.TheMtengo wa crane wokwera matani 20 ndiwotsika mtengo kwambiri.
20 matani mlatho craneali ndi ntchito zosiyanasiyana ndipo angagwiritsidwe ntchito kukweza osiyanasiyana olemera makina ndi zipangizo, zipangizo zitsulo, mapaipi, muli ndi zinthu zina. Pakupanga mafakitale, angagwiritsidwe ntchito potengera zinthu, kutsitsa ndi kutsitsa katundu pamzere wopanga, etc. M'madoko, malo osungiramo katundu ndi malo ena, angagwiritsidwe ntchito pokweza ndi kutsitsa katundu, kuyika ndi ntchito zina.
Pamene ntchitondi20 matani mlatho crane, ogwira ntchito ayenera kumvetsera nkhani zachitetezo. Ogwira ntchito ayenera kuphunzitsidwa bwino, luso logwira ntchito, ndikutsata ndondomeko zoyendetsera ntchito. Pa nthawi yomweyo, kuyendera nthawi zonse ndi kukonzamlathocrane ndiyofunikira kuti iwonetsetse kuti ikugwira ntchito bwino. Pakukweza ntchito, chidwi chiyenera kuperekedwa pakatikati pa mphamvu yokoka ndi kukhazikika kwa katundu kuti katundu asagwedezeke kapena kutsetsereka, zomwe zimayambitsa ngozi zachitetezo.
Mwachidule, a 20 matani pamwamba pa cranendi zida zonyamulira wamba zomwe zimakhala ndi mphamvu zonyamulira mwamphamvu, kukhazikika kwakukulu komanso kugwira ntchito kosavuta. Iwo amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana.
