Covob chav girder overhead craneyog cov khoom siv nqa hnyav uas siv dav hauv kev tsim khoom, tsim rau kev siv siab, nquag siv ua haujlwm. Nws tau txais kev txhawb nqa los ntawm ob lub ntsiab nqaj thiab tuaj yeem nqa qhov hnyav hnyav.
Covob chav girder overhead cranemuaj lub peev xwm thauj khoom muaj zog thiab feem ntau tuaj yeem ua cov ntaub ntawv xws li 10 tons txog 500 tons thiab siab dua. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hnyav thiab cov khoom siv loj hauv kev tsim khoom. Piv nrog rau ib leeg-girder nyiaj siv ua haujlwm cranes, ob-girder cranes tuaj yeem txhawb nqa loj dua thiab siab dua nqa qhov siab, yoog rau ntau qhov chaw ua haujlwm nyuaj.
Qhov ob girderua eot crane tus qauv ob-beam muab kev ruaj ntseg dua, tshwj xeeb tshaj yog thaum nqa cov khoom hnyav los yog cov khoom tsis zoo. Nyob rau tib lub sijhawm, nws tau nruab nrog lub siab-precision tswj system uas tuaj yeem ua tiav kev ua haujlwm ntawm crane kom ntseeg tau tias kev tuav cov khoom zoo thiab ruaj ntseg.
Tus tsim ntawm lubob girderua eot cranetuaj yeem hloov kho raws li kev thov tshwj xeeb, suav nrog kev nqa qhov siab, ncua sij hawm, muaj peev xwm thauj khoom thiab taug kev taug kev. Cov neeg siv tuaj yeem xaiv cov cuab yeej tsim nyog tshaj plaws raws li qhov xwm txheej tiag tiag ntawm lawv qhov chaw ua haujlwm, txhawm rau ua kom muaj txiaj ntsig ntau lawm.
Ob chav girder choj cranefeem ntau yog nruab nrog ntau yam kev nyab xeeb, xws li kev tiv thaiv overload, tiv thaiv kev sib tsoo thiab cov khoom siv thaum muaj xwm ceev. Cov cuab yeej siv kev nyab xeeb no tuaj yeem txo qis kev pheej hmoo ua haujlwm thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv. Ob chav girder choj crane yog ntsia rau sab saum toj ntawm lub rhiav lossis lub Hoobkas tsim, uas tsis nyob hauv av, zoo heev txhim kho kev siv tus nqi ntawm qhov chaw ua haujlwm. Qhov kev tsim no ua rau nws tshwj xeeb tshaj yog haum rau cov chaw ua haujlwm uas xav tau thaj chaw loj hauv av.
Ob chav girder overhead cranetuaj yeem ua tau raws li qhov xav tau ntawm cov chaw ua haujlwm sib txawv thiab muab cov lag luam nrog cov khoom siv tau zoo thiab nyab xeeb los ntawm kev tsim kho. Nrog rau kev loj hlob tsis tu ncua ntawm kev lag luam xav tau, ob chav girder choj cranes yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv lub neej yav tom ntej los txhawb kev tsim khoom lag luam hauv ntau yam lag luam.
