Lub crane twg siv rau kev tso girder?

Hauv kev tsim kho thiab kev tsim kho vaj tse, kev siv cov khoom hnyav kom zoo thiab muaj kev nyab xeeb yog qhov tseem ceeb heev. Ib qho ntawm cov haujlwm tseem ceeb tshaj plaws hauv kev tsim kho choj thiab cov haujlwm loj hauv kev tsim kho vaj tse yog kev tso cov girders. Rau lub hom phiaj no, ib daim khoom siv tshwj xeeb hu ua launcher girder crane raug siv.

Ib lub launcher girder craneyog tsim tshwj xeeb los tsa thiab tso cov girders loj, uas yog cov khoom tseem ceeb hauv kev tsim cov choj thiab cov overpasses. Cov cranes no tau tsim los daws cov teeb meem tshwj xeeb cuam tshuam nrog girder launching, suav nrog qhov xav tau rau qhov chaw meej thiab lub peev xwm ua haujlwm hauv qhov chaw kaw. Kev tsim ntawm lub launcher girder crane feem ntau muaj qhov ncav cuag ntev thiab lub peev xwm nqa tau zoo, tso cai rau nws los tswj cov girders hnyav rau hauv qhov chaw yooj yim.

Kev ua haujlwm ntawm lub launcher girder crane muaj ntau kauj ruam tseem ceeb. Ua ntej, lub crane tau muab tso rau ntawm qhov chaw tsim kho, feem ntau ntawm lub platform ib ntus lossis txoj kev. Thaum nyob hauv qhov chaw, lub crane lub tshuab hoisting siv los tsa lub girder ntawm nws qhov chaw thauj mus los. Tus neeg ua haujlwm crane yuav tsum ua tib zoo tswj kev txav ntawm lub girder kom ntseeg tau tias nws tau sib phim nrog cov qauv txhawb nqa. Qhov no yuav tsum muaj kev txawj ntse thiab kev sib koom tes siab, vim tias txhua qhov tsis sib xws tuaj yeem ua rau muaj kev ncua sijhawm thiab kev phom sij rau kev nyab xeeb.

Ntxiv rau cov cranes uas siv cov girder launcher ib txwm muaj, kuj muaj cov kev hloov pauv xws li cantilever launcher, uas yog qhov tshwj xeeb tshaj yog rau kev tso girders hla cov qauv lossis cov teeb meem uas twb muaj lawm. Cov cranes no tau nruab nrog cov thev naus laus zis siab heev, suav nrog cov chaw taws teeb tswj thiab cov yam ntxwv tsis siv neeg, los txhim kho kev nyab xeeb thiab kev ua haujlwm zoo thaum lub sijhawm tso tawm.

Xaus lus, lub launcher girder crane yog ib qho cuab yeej tseem ceeb hauv kev lag luam kev tsim kho, tsim tshwj xeeb rau kev nyab xeeb thiab ua haujlwm tau zoo ntawm girders. Nws cov yam ntxwv tshwj xeeb thiab peev xwm ua rau nws yog qhov kev xaiv mus-rau rau cov engineers thiab cov neeg cog lus koom nrog hauv cov haujlwm loj hauv kev tsim kho vaj tse.
