Uma kukhulunywa ngezinto ezihambayo endaweni yokugcina impahla noma endaweni yezimboni, ama-jib cranes angamathuluzi abalulekile. Kunezinhlobo ezimbili eziyinhloko zama-jib crane, okuhlanganisa ama-jib cranes afakwe phansi esisekelo kanye nama-cranes aphansi angenasisekelo. Zombili zinezinzuzo nezingozi zazo, futhi ukukhetha ekugcineni kuncike ezidingweni ezithile zephrojekthi.
Okhrayini be-jib abagibele isisekelo baklanyelwe ukugxunyekwa phansi. Anesisekelo esiqinile esifakwe ihange phansi futhi singasetshenziswa ukuphakamisa nokuhambisa izinto endaweni. Lawa ma-cranes aziwa ngokuhlala kwawo kanye nokuzinza, okuwenza abe yinketho edumile yezinhlelo zokusebenza ezisindayo. Isitezi sesisekelo sifakweama-cranes ama-jibingasetshenziswa ukuhambisa izinto ngokunyakaza okuyindilinga, okuzenza zilungele izindawo ezinendawo elinganiselwe.
Ngakolunye uhlangothi, ama-jib cranes aphansi angenasisekelo aklanyelwe ukuthi aphatheke. Lama-cranes awagxiliwe phansi, okusho ukuthi angahanjiswa ezindaweni ezahlukene njengoba kudingeka. Zivame ukusetshenziselwa izinhlelo zokusebenza ezilula futhi zinganyakaziswa kalula endaweni. Ama-cranes angenasisekelo aphansi ngokuvamile abiza kancane kunama-cranes afakwe phansi esisekelo, okuwenza abe yinketho edumile kumabhizinisi amancane noma lawo anesabelomali esiqinile.
Zombili izinhlobo zama-cranes zinezinzuzo zazo kanye nezinkinga zazo. Ama-cranes afakwe phansi esisekelo anikeza ukuzinza nokuqina, okuwenza abe ukukhetha okuhle ezinhlelweni zokusebenza ezinzima. Kodwa-ke, aziphatheki njengama-cranes aphansi angenasisekelo. Ngakolunye uhlangothi, ama-jib cranes angenasisekelo aphansi, ayaphatheka futhi ayavumelana nezimo, okuwenza abe ukukhetha okuhle kwezicelo zomsebenzi wokukhanya noma kumabhizinisi anesabelomali.
Sengiphetha, ukukhetha phakathi kwama-jib cranes afakwe phansi esisekelo kanye nama-cranes e-jib angenasisekelo ancike ezidingweni ezithile zephrojekthi. Zombili izinhlobo zama-cranes zinezinzuzo zazo ezihlukile, futhi kubalulekile ukucabangela lezi zici ngaphambi kokuthatha isinqumo.
