Mapangidwe mwamakonda akuyambitsa gantry crane kuti amange mlatho

Kireni yoyambira girder gantry, makina onyamulira amphamvu komanso osunthika, yakhala chida chofunikira kwambiri pantchito yomanga.Cholinga chake chachikulu ndikuthandizira pakumanga ndikukhazikitsa milatho, ma viaducts, ndi misewu yayikulu.Crane iyi imagwira ntchito yofunika kwambiri pakukweza mosamala zida zolemetsa, monga zomangira za konkriti, ndikuziyika m'malo omwe asankhidwa.

Tsopano, tiyeni tiwone momwe zimapangidwira zomwe zimapangitsa kuti girder gantry crane ikhale yodziwika bwino padziko lonse lapansi yomanga.Pakatikati pa crane iyi pali chimango cholimba chomwe chimapereka bata ndi chithandizo panthawi yokweza.Chimangochi nthawi zambiri chimapangidwa ndi zitsulo zamtengo wapatali, zomwe zimatsimikizira kuti zimakhala ndi mphamvu zambiri komanso zimakhala zolimba.Zimapangidwa ndi mizati yowongoka, zomangira zopingasa, ndi zomangira zozungulira, zonse zidapangidwa mwaluso kuti zithe kupirira katundu wolemetsa komanso kukhala okhazikika pakagwa zovuta.

Chimodzi mwazinthu zodziwika bwino pakuyambitsa girder gantry crane ndi mayendedwe ake osinthika.Njirazi, zomwe zili mbali zonse za crane, zimalola kuyenda mosavuta pafupi ndi malo omanga.Ndi kutha kukulitsa kapena kubweza, crane imatha kutengera mipata yosiyanasiyana ya mlatho, kuwonetsetsa kuti ili bwino panthawi yokweza.Kusintha kumeneku ndikofunikira makamaka popanga ma projekiti ovuta omanga okhala ndi ma geometries osiyanasiyana.

Pofuna kuthandizira kukweza, crane imagwiritsa ntchito njira zingapo zonyamulira.Njira yayikulu yonyamulira nthawi zambiri imakhala hydraulic jack system, yomwe imapereka mphamvu yofunikira kukweza zinthu zolemetsa.Ma jacks awa amayikidwa bwino m'mbali mwa chotchinga chachikulu, zomwe zimalola kugawa katundu wofanana pakukweza.Kuphatikiza apo, crane ili ndi zida zothandizira monga zotuluka ndi zokhazikika, zomwe zimapangitsa kukhazikika ndikuchepetsa kugwedezeka kulikonse kapena kupendekeka komwe kungachitike panthawi yokweza.

Chitetezo ndichofunikira kwambiri pantchito iliyonse yomanga, ndipo crane yoyambira girder gantry ndi chimodzimodzi.Chifukwa chake, ili ndi zida zingapo zotetezera.Izi zikuphatikizapo zosinthira malire, mabatani oyimitsa mwadzidzidzi, ndi machitidwe oteteza mochulukira.Njirazi zimawonetsetsa kuti crane imagwira ntchito molingana ndi momwe ilili ndikupewa ngozi zilizonse zomwe zingachitike kapena kuwonongeka chifukwa chakuchulukirachulukira.Kuphatikiza apo, crane idapangidwa kuti ikhale ndi zida zotsutsana ndi nsonga komanso masensa othamanga amphepo kuti athe kuthana ndi nyengo yoyipa, kuonetsetsa chitetezo cha onse ogwira ntchito komanso malo omanga.
