Thaum kawg, koj yuav paub meej tias yuav ua li cas kom nce qhov siab qhov siab yam tsis muaj kev txhim kho koj qhov chaw lossis crane system.
Nyiaj siv ua haujlwm crane, qis headroom overhead cranes
Yam Tseem Ceeb Uas Ncaj Ncees Lifting Qhov siab
Qhov siab tshaj qhov nqa qhov siab ntawm lub overhead crane tsis yog hais txog kev yuav lub crane loj dua. Ob peb yam ua tau los txiav txim siab npaum li cas koj tuaj yeem nqa tau zoo thiab ua tau zoo. Paub lawv yuav pab koj xaiv cov kev xaiv ntse yam tsis tas yuav siv nyiaj lossis poob sijhawm.
Clear Qhov siab muaj
Qhov siab ntshiab yog qhov ntsug nrug nruab nrab ntawm hauv pem teb thiab thawj qhov kev cuam tshuam ntawm lub taub hau. Qhov no tuaj yeem yog lub qab nthab, lub teeb pom kev zoo, HVAC duct, lossis txawm tias lub qhov rooj qhov rooj. Nws yog thawj qhov kev txwv uas koj yuav tsum xav txog vim yog tias tsis muaj chaw txaus, tsis muaj dab tsi ntxiv tuaj yeem them rov qab.
Tshawb xyuas cov teeb meem xws li cov kab teeb ci qab nthab, cov kav dej, cov kav dej, lossis cov lem uas tuaj yeem txav los yog hloov kho.
Txawm tias qhov kev hloov me me, xws li tsa lub qhov rooj khiav los yog cov kav dej rov qab, tuaj yeem ntxiv qhov muaj peev xwm nqa tau zoo.
Ib txwm ntsuas los ntawm hauv av mus rau qhov qis tshaj qhov thaiv, tsis yog saum lub crane xwb.
Cov tswv yim tswv yim: Qee lub sij hawm qhov kev hloov me me tuaj yeem muab rau koj ob peb centimeters ntxiv ntawm kev nqa qhov siab, uas tuaj yeem ua rau muaj qhov sib txawv loj rau qhov siab lossis qhov hnyav.
Hom Nyiaj Siv Ua Haujlwm Crane
Hom crane hnyav hnyav rau kev nqa qhov siab vim li cas lub hoist txav mus rau lub girder.
Ib leeg-girder cranes: Lub hoist taug kev nyob rau hauv lub beam, uas txo qhov siab tshaj plaws nuv.
Ob chav girder cranes: Hoist txav saum lub girders, muab lub peev xwm nqa siab tshaj plaws. Cov khoom loj tuaj yeem xav tau cov khoom siv ntxiv, txawm li cas los xij.
