Ikhabethe lawula ukwakhiwa ngaphansi kwezimboni zezimboni ze-gantry crane

Ngokuya ngezidingo zomsebenzi othize, ama-cantry wezimboni zezimboni angahlelwa ngama-girders amakhulu kakhulu, ama-gibeli embonini. Amandla okulayisha max we-geam Gantry Crane angaba ngamathani angama-600, i-span ingamamitha angama-40, futhi ukuphakama okuphezulu kufinyelela kumamitha angama-20. Ngokusekelwe kuhlobo lwedizayini, ama-gantry ama-cranes angaba ne-girder eyodwa noma ephindwe kabili. I-Double-Bridds uhlobo olunzima lwe-gantry cranes, ngamakhono aphezulu aphezulu uma kuqhathaniswa nama-cranes we-girner-girder. Lolu hlobo lwe-crane lusetshenziselwa ukusebenza ngezinto ezinkulu zokwakha, ezengeziwe ezisebenzayo.

Izimboni ze-Gantry Crane zivumela ukuphakanyiswa nokuphathwa kwezinto, imikhiqizo eqediwe, kanye nezinto zokwakha okujwayelekile. Ama-gantry ama-gantry wezimboni aphakamisa izinto ezisindayo, futhi angahamba ngohlelo lonke lokulawula lapho alayishwa. Iphinde isetshenziselwe ukugcinwa kwezitshalo nasezinhlelweni zokulungiswa kwezimoto lapho imishini idinga ukuhanjiswa futhi ithathelwe indawo. Ama-cranes asebenza kanzima e-gantry ashesha futhi kulula ukusetha futhi adilize phansi, abenze baphelele izikhungo zokuqasha noma ezindaweni eziningi zokusebenza.
