Zida zonyamulira mafakitale ogwiritsira ntchito swivel 3 ton jib crane ndi mtundu wa zida zonyamulira zida zopepuka, zomwe zimapulumutsa mphamvu komanso zothandiza. Itha kugwiritsidwa ntchito kwambiri m'mafakitale, migodi, malo ogwirira ntchito, mizere yopanga, mizere yophatikizira, kutsitsa ndi kutsitsa zida zamakina, malo osungiramo zinthu, ma docks ndi zochitika zina zamkati ndi zakunja kukweza katundu.
Makina ogwiritsira ntchito swivel jib crane ali ndi ubwino wa masanjidwe oyenera, msonkhano wosavuta, ntchito yabwino, kasinthasintha wosinthika komanso malo akulu ogwirira ntchito.
Zigawo zazikulu za pillar jib crane ndizokhazikika pansi pa konkriti, cantilever yomwe imazungulira madigiri a 360, chokwera chomwe chimayendetsa katundu mmbuyo ndi mtsogolo pa cantilever, ndi zina zotero.
Chokwezera magetsi ndi njira yokwezera makina opangira ma 3 ton jib crane. Posankha crane ya cantilever, wogwiritsa ntchito amatha kusankha chokweza pamanja kapena chokweza chamagetsi (chokweza chingwe kapena chingwe chokweza) molingana ndi kulemera kwa katundu woti anyamule. Pakati pawo, ogwiritsa ntchito ambiri amasankha ma hoist chain chain.
Mukamagwiritsa ntchito pillar jib crane m'nyumba monga mzere wopanga ma workshop, nthawi zambiri amagwiritsidwa ntchito limodzi ndi crane ya mlatho. Crane ya mlatho imayenda cham'mbuyo ndi mtsogolo panjira yomwe idayikidwa pamwamba pa msonkhano kuti igwire ntchito yokweza, ndipo malo ake ogwirira ntchito ndi rectangle. Chogwirira ntchito cha swivel jib crane chimakhazikika pansi, ndipo malo ake ogwirira ntchito ndi malo ozungulira okhazikika omwe ali pakatikati. Imayang'anira kwambiri ntchito zonyamulira malo ogwirira ntchito mtunda waufupi.
Pillar jib crane ndi zida zonyamulira zotsika mtengo, zotsika mtengo, zosinthika, zolimba komanso zolimba. Ili ndi dongosolo lasayansi komanso lololera, ndi losavuta komanso losavuta kugwiritsa ntchito, limachepetsa kwambiri kupanikizika kwa ntchito zamayendedwe ochita kupanga, ndipo limathandizira kwambiri magwiridwe antchito amakampani osiyanasiyana.
