Crane yapansi yoyendetsedwa ndi magetsi imayendetsedwa ndi mota yamagetsi yogwira bwino ntchito, kupangitsa kuti ikhale yosavuta kugwira ntchito. Imathandizira kusuntha kwachangu komanso kosalala kwa katundu ndikukweza zinthu, kuchepetsa mphamvu ya anthu, nthawi, ndi kuyesetsa. Chokhala ndi zinthu zachitetezo monga chitetezo chochulukirachulukira, mabuleki odziwikiratu, ndi zowongolera zolondola, crane yapansi iyi imathandizira chitetezo cha ogwira ntchito ndi zida.

Ili ndi mkono wowonera magawo atatu womwe umalola kunyamula katundu mosavuta mpaka 2.5 metres. Chigawo chilichonse cha mkono wa telescopic chimakhala ndi kutalika kwake komanso mphamvu yonyamula katundu. Pamene mkono ukukwera, mphamvu yake yolemetsa imachepa. Akatalikitsidwa mokwanira, mphamvu yolemetsa imatsika kuchokera pa 1,200 kg mpaka 300 kg. Chifukwa chake, musanagule crane yapansi panthaka, ndikofunikira kupempha chojambulira chonyamula katundu kuchokera kwa wogulitsa kuti muwonetsetse kuti ntchito yoyenera ndi yotetezeka.

Kaya amagwiritsidwa ntchito m'malo osungiramo zinthu, malo opangira zinthu, malo omanga, kapena mafakitale ena, makina athu amagetsi amathandizira kuti magwiridwe antchito azigwira ntchito bwino komanso azigwira ntchito bwino.
