Crane ya Gantry ni ikiraro cyubwoko bwikiraro ikiraro cyacyo gishyigikirwa kumurongo wubutaka binyuze mumashanyarazi kumpande zombi. Mu buryo bwubaka, igizwe na mast, uburyo bwo gukora trolley, trolley yo guterura nibice byamashanyarazi. Crane zimwe za gantry zifite outriggers kuruhande rumwe, kurundi ruhande rushyigikiwe ninyubako yinganda cyangwa trestle, bita aigice cya gantry. Crane ya gantry igizwe nurwego rwo hejuru rwikiraro (harimo urumuri nyamukuru nigiti cyanyuma), outriggers, ibiti byo hepfo nibindi bice. Kugirango wagure ibikorwa bya crane ikora, urumuri nyamukuru rushobora kwaguka kurenga kuri outriggers kugera kumpande imwe cyangwa zombi kugirango zikore kantileveri. Trolley yo guterura hamwe na boom irashobora kandi gukoreshwa mugukwirakwiza ibikorwa bya crane ikoresheje mukuzunguruka no kuzunguruka.
1. Gushira mu byiciro
GantryBirashobora gushyirwa mubice ukurikije imiterere yikadiri yumuryango, imiterere yigitereko nyamukuru, imiterere yibiti nyamukuru, nuburyo bwo gukoresha.
a. Imiterere y'urugi
1. Crane yuzuye ya gantry: urumuri nyamukuru ntirurenga, kandi trolley igenda mumwanya munini;
2. Semi-gantry crane: Abasohoka bafite itandukaniro ryuburebure, bushobora kugenwa hakurikijwe ibyangombwa byubwubatsi bwa site.
b. Cantilever gantry crane
1. Kantilever ebyiri ya gantry crane: Imiterere ikunze kugaragara, guhangayikishwa nuburyo no gukoresha neza ikibanza birumvikana.
2. Kantilever imwe ya gantry crane: Iyi fomu yuburyo ikunze gutoranywa kubera kubuza urubuga.
c. Ifishi nyamukuru
1.Ibiti by'ingenzi
Imashini imwe nyamukuru ya girder gantry crane ifite imiterere yoroshye, yoroshye kuyikora no kuyishiraho, kandi ifite misa nto. Umukandara nyamukuru ahanini ni agasanduku k'imiterere. Ugereranije na bibiri bya girder gantry crane, gukomera muri rusange ni ntege. Kubwibyo, iyi fomu irashobora gukoreshwa mugihe ubushobozi bwo guterura Q≤50t hamwe na S≤35m. Umukandara umwe wa gantry crane amaguru arahari muburyo bwa L na C-bwoko. Ubwoko bwa L bworoshye gukora no gushiraho, bufite imbaraga zo guhangana ningutu, kandi bufite misa nto. Ariko, umwanya wo guterura ibicuruzwa kunyura mumaguru ni muto. Amaguru ya C akozwe muburyo bugoramye cyangwa bugoramye kugirango habeho umwanya munini kuruhande kugirango ibicuruzwa bishobore kunyura mumaguru neza.

Double main girder gantry crane ifite imbaraga zikomeye zo kwikorera imitwaro, umwanya munini, umutekano mwiza muri rusange, nubwoko bwinshi. Ariko, ugereranije numurongo umwe wingenzi wa girder gantry crane ifite ubushobozi bumwe bwo guterura, ubwinshi bwabo ni bunini kandi ikiguzi ni kinini. Ukurikije ibyingenzi bitandukanye byubatswe, birashobora kugabanwa muburyo bubiri: agasanduku kameza na truss. Mubisanzwe, agasanduku kameze nkibikoresho bikoreshwa.
d. Imiterere nyamukuru
1.Truss beam
Imiterere yubatswe yasizwe nicyuma cyangwa I-beam ifite ibyiza byo kugiciro gito, uburemere bworoshye hamwe no guhangana numuyaga mwiza. Nyamara, kubera umubare munini wogusudira hamwe nubusembwa bwa truss ubwayo, urumuri rwa truss narwo rufite inenge nko gutandukana kwinshi, gukomera guke, kwizerwa gake, no gukenera gutahura kenshi aho gusudira. Irakwiriye kurubuga rufite umutekano muke hamwe nubushobozi buke bwo guterura.
2.Box beam
Isahani yicyuma isudira mumasanduku yububiko, ifite ibiranga umutekano muke no gukomera. Mubisanzwe bikoreshwa kuri tonnage nini na ultra-nini-tonnage gantry crane. Nkuko bigaragara ku ishusho iburyo, MGhz1200 ifite ubushobozi bwo guterura toni 1200. Nicyo kinini kinini cya gantry mu Bushinwa. Igiti nyamukuru gifata agasanduku kegeranye. Agasanduku k'ibisanduku kandi gafite ingaruka mbi zihenze cyane, uburemere buremereye, hamwe n’umuyaga muke.
3.Ibiti by'ubuki
Mubisanzwe byitwa "isosceles triangle triangle" Ibiti by'ubuki bikurura ibiranga ibiti bya truss n'ibiti by'agasanduku. Ugereranije n'ibiti bya truss, bifite gukomera gukomeye, gutandukana bito, no kwizerwa cyane. Ariko, kubera gukoresha ibyuma byo gusudira ibyuma, uburemere-bwikiguzi hamwe nigiciro kiri hejuru gato ugereranije nibiti bya truss. Irakwiriye kurubuga cyangwa kumurongo wibikoresho bikoreshwa kenshi cyangwa ubushobozi bwo guterura biremereye. Kubera ko ubu bwoko bwibiti ari ibicuruzwa byemewe, hari ababikora bake.
Ifishi yo gukoresha
1. Gantry isanzwe
2.Hidropower station gantry crane
Ikoreshwa cyane cyane mu guterura, gufungura no gufunga amarembo, kandi irashobora no gukoreshwa mubikorwa byo kwishyiriraho. Ubushobozi bwo guterura bugera kuri toni 80 kugeza kuri 500, uburebure ni buto, metero 8 kugeza kuri 16, kandi umuvuduko wo guterura uri hasi, metero 1 kugeza kuri 5 / min. Nubwo ubu bwoko bwa kane butaterurwa kenshi, akazi kararemereye cyane iyo kamaze gukoreshwa, bityo urwego rwakazi rugomba kongerwa muburyo bukwiye.
3. Ubwubatsi bwa gantry crane
Byakoreshejwe guteranya hull kumurongo, inzira ebyiri zo guterura ziraboneka burigihe: imwe ifite ibyuma bibiri byingenzi, biruka kumuhanda kumurongo wo hejuru wikiraro; ikindi gifite icyuma gikuru hamwe nigikoresho gifasha, kumurongo wo hepfo wikiraro. Koresha kumurongo kugirango uhindure kandi uzamure ibice binini bya hull. Ubushobozi bwo guterura muri rusange ni toni 100 kugeza 1500; uburebure bugera kuri metero 185; umuvuduko wo guterura ni metero 2 kugeza kuri 15 / min, kandi hariho umuvuduko wa micro ya 0.1 kugeza 0.5 metero / min.
3. Urwego rw'akazi
Gantry crane nayo ni urwego rwakazi A ya gantry crane: irerekana ibiranga akazi ka kane mubijyanye numutwaro no gukoresha cyane.
Igabana ryurwego rwakazi rugenwa nurwego rwo gukoresha urwego rwa U hamwe nuburyo umutwaro Q. Bagabanijwe mubice umunani kuva A1 kugeza A8.
Urwego rwakazi rwa crane, ni ukuvuga urwego rwakazi rwimiterere yicyuma, rugenwa ukurikije uburyo bwo guterura kandi rugabanijwe murwego A1-A8. Niba ugereranije nubwoko bukora bwa crane zerekanwe mubushinwa, birasa hafi na: A1-A4-urumuri; A5-A6- Hagati; A7-iremereye, A8-iremereye.
