Gantry cranes yog cov chaw ua haujlwm zoo tshaj plaws rau ntau qhov kev lag luam thiab kev siv. Kab lus no tsom mus rau gantry cranes hauv qeb ib-tuj mus rau tsib-tuj. Cov neeg siv khoom xav txog kev yuav lub gantry crane yuav tsum paub cov lus teb rau qee cov lus nug thaum lub sijhawm yuav khoom txhawm rau txhawm rau txhim kho lub crane kom zoo. Kab lus no muab cov lus teb rau cov lus nug no.
Qhov siab thiab qhov dav yog ob qho tseem ceeb uas yuav tsum tau xav txog.
Qhov siab xav txog:
Kev cuam tshuam qis tshaj plaws ntawm thaj chaw ua haujlwm - Dab tsi yog qhov khoom qis tshaj plaws hauv thaj chaw ua haujlwm uas yuav siv thiab / lossis txav los ntawm lub gantry crane? Koj yuav tsum xyuas kom meej tias lub crane tuaj yeem muab tso rau hauv thiab txav mus (yog tias tsim nyog), nws tuaj yeem nkag mus thiab tawm ntawm qhov chaw ua haujlwm, thiab nws tuaj yeem ntsia tau rau hauv qab ntawm qhov khoom qis tshaj ncaj qha saum chaw ua haujlwm. Qhov kev cuam tshuam qis tshaj ntawm lub taub hau tuaj yeem yog lub qab nthab, cov kab hluav taws xob txhawb nqa, cov twj tso kua mis, ib feem ntawm HVAC system, kav dej, railings, thiab lwm yam.
Zuag qhia tag nrho qhov siab:Tag nrho qhov siab ntawm lub gantry crane feem ntau suav nrog qhov kev ncua deb ntawm av (xws li casters) mus rau sab saum toj ntawm I-beam. Yog hais tias lub crane yog ib qhov siab adjustable qauv nrog ib qhov siab ntawm 7'6' mus rau 14'0' hauv qab ntawm I-beam, tag nrho qhov siab nrog rau casters yog qhov ntau ntawm kev ntsuas (tsawg mus rau siab) ntxiv rau qhov siab. ntawm I-beam.
Qhov siab hauv qab beam:Qhov siab nyob rau hauv lub beam yog ntsuas los ntawm hauv av mus rau hauv qab ntawm lub I-beam. Ntxiv dua thiab, rho tawm qhov siab ntawm I-beam los ntawm tag nrho qhov siab sib npaug ntawm qhov siab hauv qab I-beam.
Hook Height Requirement: Qhov no yog kab tias qhov tseem ceeb tshaj qhov siab xav tau. Nws yog qhov ntsuas los ntawm hauv av mus rau qhov siab tshaj plaws nyob rau sab hauv qab ntawm tus nuv thaum lub load yog ruaj rau tus nuv. Nco ntsoov xav txog qhov slackness ntawm cov saw, slings, thiab lwm yam siv los nqa lub load.
Lifting qhov siab:Lub laub thiab nqa khoom sib txawv ntawm qhov loj thiab qhov siab. Yog tias qhov kev txwv qhov siab tag nrho yog nruj, koj yuav tsum tau nrhiav lub trolley thiab nqa kev sib xyaw ua ke uas ua tau raws li koj qhov kev xav tau 'lift height'. Tag nrho qhov siab ntawm lub laub thiab nqa mus rau sab hauv ntawm tus nuv hauv qab ntawm lub nqa yog hu ua 'qhov siab ntshiab'. Qhov siab ntshiab yog ntsuas los ntawm lub hauv qab ntawm lub trolley rollers mus rau sab hauv ntawm lub hauv qab nuv ntawm lub nqa (thaum txuas rau lub trolley). Yog tias koj xav tau qhov tseeb, koj tuaj yeem ntxiv qhov tuab ntawm flange thickness ntawm I-nqaj uas lub trolley rollers zaum. Yog tias koj xav txo qhov siab, nrhiav lub laub / nqa nrog 'qhov muag mount'. Hom trolley thiab nqa no yog mounted rau saum ib leeg, txo qhov chaw lawv coj mus rau hauv ib qho kev teeb tsa gantry.
Chain poob: Hoists muaj nyob nrog cov saw ntev sib txawv. Chain poob yog tus nqi ntawm cov saw hlau uas muaj rau kev nqa. Yog hais tias cov saw poob yog 15 ko taw, tom qab tag nrho txuas ntxiv muaj 15 feet ntawm cov saw siv tau los ntawm lub hoist mus rau tus nuv. Nco ntsoov ntsuas qhov siab ntawm qab nthab thiab qhov yuav tsum tau mus qis dua qib thaum txiav txim siab cov kev xav tau ntawm cov hlua khi. Piv txwv li, hais tias koj muaj qhov xav tau qhov siab ntawm 10' thiab 2 '6' clearance rau lub trolley thiab hoist. Ua ntej, lub gantry crane yuav tsum tau ntsib lossis tshaj 12 '6' hauv qab qhov siab I-beam (10' nuv qhov siab. + 2 '6" tshem tawm). Yog tias peb xaiv tus qauv crane nrog qhov siab ntawm 14' hauv qab ntawm I-nqaj, dab tsi yog qhov yuav tsum tau cov saw hlau poob kom ncav cuag qhov taw tes 2' saum toj no? Teb: 14' rho tawm 2 '6 "qhov siab sib npaug sib npaug qhov siab ntawm 11 '6" (uas tshaj li 10' hooks qhov siab xav tau). Txhawm rau kom ncav cuag qhov hnyav 2 "siab dua hauv pem teb. Muab cov kev xaiv nrov, cov saw hlau poob ntawm 3" tuaj yeem raug xaiv. Yog li txawm tias qhov siab hauv qab I-beam yog 14', koj tsuas yog xav tau tus qauv 10' saw poob rau ncav cuag ib tug nuv taw tes 2' saum toj no hauv pem teb.
Kev kho qhov siab: Rau qhov siab-hloov qauv, tej zaum koj yuav xav xav txog cov khoom siv kho qhov siab kom koj tuaj yeem kho qhov siab ntawm cov nqaj tau yooj yim. Rau cov qauv steel, lub nqaj tuaj yeem hnyav heev, suav txog li ib feem peb ntawm tag nrho qhov hnyav ntawm crane. Txhawm rau hloov qhov siab yooj yim dua, xav txog aluminium crane, uas yog kim dua tab sis tsawg dua? ntawm tag nrho qhov hnyav ntawm steel crane.
Safety clearance xav txog:
Muaj ob qhov kev ntsuas kom ceeb toom rau qhov dav, lossis qhov dav, ntawm lub gantry crane. Thawj qhov yog qhov dav dav, uas tsuas yog qhov ntev ntawm sab nrauv mus rau sab nrauv ntawm kab teeb thiab ob txhais ceg. Gantry cranes muaj qhov kawg nres los tiv thaiv lub trolley los ntawm dov tawm ntawm lub nqaj thiab / lossis lub hauv paus phaj (siv thaum ob txhais ceg thiab nqaj yog haum ua ke thiab thaum lawv tau welded), uas txhais tau hais tias lub trolley yuav tsis yob tag nrho ntev ntawm lub nqaj. , thiab qhov no yuav tsum tau coj mus rau hauv tus account thaum txiav txim siab qhov yuav tsum tau beam dav. Usable width' ntsuas qhov kev ncua deb ntawm qhov kawg cov ntsiab lus uas lub trolley nres ntawm ob sab. Qhov dav siv tau yog kwv yees li 2.6 ntiv tes tsawg dua qhov dav dav dav.
Capacity:Nco ntsoov tias lub peev xwm ntawm lub hoist tsis pub dhau lub peev xwm ntawm crane lossis trolley. Qhov zoo tshaj plaws crane, trolley thiab pallet yuav tsum muaj tib lub peev xwm. Los ntawm sab saum toj mus rau hauv qab, lub peev xwm ntawm lub gantry yuav tsum sib npaug los yog ntau tshaj qhov muaj peev xwm ntawm lub trolley, thiab lub peev xwm ntawm lub trolley yuav tsum sib npaug los yog ntau dua li lub peev xwm ntawm lub hoist. Tag nrho cov khoom ntawm lub gantry system yuav tsum sib npaug los yog tshaj qhov siab tshaj qhov hnyav - txawm li cas los xij, qhov no yuav tsum tsis txhob dhau ntau dhau. Xaiv lub peev xwm uas ze tshaj plaws rau lub nra uas yuav ua tiav txoj haujlwm. Cov nyiaj siv ua haujlwm cranes feem ntau raug sim ntawm 125% ntawm lawv cov peev txheej ntsuas, yog li tsis tas yuav ua rau nws dhau.
Armed nrog cov kev paub no, koj tam sim no npaj txhij yuav ib lub gantry crane.
