Covob chav girder overhead craneyog lub luag haujlwm hnyav nqa kev daws teeb meem feem ntau siv hauv kev lag luam uas yuav tsum tau muaj zog, muaj peev xwm tuav cov khoom siv. Hom crane no muaj ob qho tib si girders hla qhov dav ntawm qhov chaw ua haujlwm, muab kev ruaj ntseg ntau dua thiab muaj peev xwm thauj khoom ntau dua li ib leeg-girder cranes. Cov nyiaj siv ua haujlwm cranes no zoo tagnrho rau cov ntawv thov xws li kev tsim steel, tsheb sib dhos, nkoj tsim, thiab lwm qhov chaw xav tau siab uas qhov precision thiab durability yog qhov tseem ceeb.
Thaum xav txog cov kev daws teeb meem hnyav hnyav, nkag siab txog qhovob girderua eot crane nqiNws yog ib qho tseem ceeb rau kev siv nyiaj txiag loj hauv kev lag luam.
Tus qauv ntawm aob chav girder overhead cranefeem ntau suav nrog:
Ob chav Girders: Ob lub ntsiab girders uas ris lub nra, muab lub crane muaj peev xwm nqa cov khoom hnyav.
End Trucks: Nyob rau ntawm qhov kawg ntawm cov girders, cov no pab txhawb kev txav mus los ntawm ob chav girder eot crane txoj kev khiav, ua rau txoj kab rov tav mus ncig ntawm qhov chaw ua haujlwm.
Hoist thiab Trolley: Muab tso rau nruab nrab ntawm ob lub girders, lub hoist thiab trolley txav raws qhov ntev ntawm lub girders, ua kom muaj kev txav ntsug thiab kab rov tav.
Electric Tsav thiab Tswj System: Lubob chav girder eot cranetxav, hoisting, thiab lwm yam haujlwm yog tswj los ntawm lub tshuab hluav taws xob, feem ntau nrog cov chaw taws teeb lossis xov tooj cua tswj kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Covob girderua eot crane nqituaj yeem sib txawv nyob ntawm qhov tshwj xeeb xws li lub peev xwm thauj khoom, ncua, thiab kev xaiv kev xaiv.
Kev saib xyuas tsis tu ncua ntawm crane cov khoom—xws li lub hoist, tswj systems, thiab structural moj khaum—yog qhov tseem ceeb rau kev nyab xeeb thiab ua haujlwm tau zoo. Lub sijhawm tu yuav tsum suav nrog kev tshuaj xyuas lub cev muaj zog, lub tshuab nres, thiab cov khoom siv thauj khoom kom ntseeg tau tias muaj kev ntseeg siab thiab tiv thaiv kom tsis txhob poob siab.
