Lub launching girder gantry crane, lub tshuab nqa muaj zog thiab ntau yam, tau dhau los ua cov cuab yeej tseem ceeb hauv kev tsim kho kev lag luam.Nws lub hom phiaj tseem ceeb yog los pab kev tsim kho thiabinstallation ntawm cov choj, viaducts, thiab elevated highways.Lub crane no ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb nqa cov khoom hnyav, xws li cov pob zeb ua ntej, thiab muab tso rau hauv lawv txoj haujlwm.
Tam sim no, cia peb delve rau hauv cov yam ntxwv yam ntxwv uas ua rau lub launching girder gantry crane ib tug standout nyob rau hauv lub ntiaj teb no ntawm kev tsim kho.Ntawm lub hauv paus ntawm lub crane no yog lub hauv paus muaj zog uas muab kev ruaj ntseg thiab kev txhawb nqa thaum lub sijhawm nqa kev ua haujlwm.Lub moj khaum no feem ntau yog ua los ntawm cov hlau zoo, ua kom lub zog siab tshaj plaws thiab kav ntev.Nws muaj cov kab ntsug, kab rov tav girders, thiab kab pheeb ces kaum bracing, tag nrho cov kev tsim kho kom zoo los tiv thaiv cov khoom hnyav thiab tswj kev ruaj ntseg hauv cov xwm txheej tsis zoo.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm lub launching girder gantry crane yog nws cov lem adjustable.Cov lem no, nyob rau ntawm ob sab ntawm lub crane, tso cai rau yooj yim txav raws qhov chaw tsim kho.Nrog lub peev xwm los txuas ntxiv lossis thim rov qab, lub crane tuaj yeem hloov kho rau ntau yam kev sib txuas, kom ntseeg tau qhov chaw zoo thaum lub sijhawm nqa.Qhov kev hloov kho no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua tiav cov phiaj xwm kev tsim kho nyuaj nrog cov geometry sib txawv.
Txhawm rau txhawb nqa kev ua haujlwm, lub crane siv ntau lub tshuab nqa nqa.Lub ntsiab lifting mechanism feem ntau yog hydraulic jack system, uas muab lub zog xav tau los txhawb nqa cov khoom hnyav precast.Cov jacks no tau muab tso rau hauv lub ntsiab girder, uas tso cai rau kev thauj khoom tsis sib xws thaum nqa.Tsis tas li ntawd, lub crane tau nruab nrog cov cuab yeej pab cuam xws li outriggers thiab stabilizers, uas txhim khu kev ruaj ntseg thiab txo qis kev swaying lossis tilting uas tuaj yeem tshwm sim thaum lub sijhawm nqa.
Kev nyab xeeb yog qhov tseem ceeb tshaj plaws nyob rau hauv txhua qhov kev tsim kho, thiab kev xa tawm girder gantry crane tsis muaj qhov tshwj xeeb.Yog li, nws yog txawm peem rau nrog ib tug array ntawm kev ruaj ntseg nta.Cov no suav nrog kev txwv kev hloov pauv, khawm nres thaum muaj xwm txheej ceev, thiab lub tshuab tiv thaiv overload.Cov kev ntsuas no xyuas kom meej tias lub crane ua haujlwm nyob rau hauv nws lub peev xwm tshwj xeeb thiab tiv thaiv kev sib tsoo lossis kev puas tsuaj vim yog overload.Tsis tas li ntawd, lub crane yog tsim los nrog cov khoom siv los tiv thaiv tipping thiab cua ceev sensors los tswj cov huab cua phem, ntxiv kom muaj kev nyab xeeb ntawm ob tus neeg ua haujlwm thiab qhov chaw tsim kho.
