Ib tug ib leeg girder gantry crane yog ib hom crane uas muaj ib tug choj girder txhawb los ntawm ob tug A-ncej ceg ntawm ob sab. Nws yog feem ntau siv rau kev nqa thiab txav cov khoom hnyav hauv qhov chaw sab nraum zoov, xws li chaw xa khoom, chaw tsim khoom, warehouses, thiab chaw tsim khoom.
Nov yog qee qhov tseem ceeb thiab cov yam ntxwv ntawmib leeg girder gantry cranes:
Choj Girder: Tus choj girder yog kab rov tav kab uas hla qhov sib txawv ntawm ob txhais ceg ntawm lub gantry crane. Nws txhawb nqa lub tshuab nqa thiab nqa lub nra thaum ua haujlwm. Ib leeg-girder gantry cranes muaj ib tus choj girder, uas ua rau lawv sib zog thiab siv nyiaj ntau dua piv rau ob chav girder gantry cranes.
Ob txhais ceg thiab kev txhawb nqa: Cov ceg A-ncej muab kev ruaj ntseg thiab kev txhawb nqa rau cov qauv crane. Cov ceg no feem ntau yog ua los ntawm cov hlau thiab txuas nrog hauv av los ntawm kev taw lossis lub log rau kev txav mus los. Qhov siab thiab dav ntawm ob txhais ceg tuaj yeem sib txawv nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov.
Lifting Mechanism: Ib leeg girder gantry cranes tau nruab nrog lub tshuab nqa, xws li hluav taws xob hoist lossis lub trolley, uas txav raws qhov ntev ntawm lub girder. Lub lifting mechanism yog siv los tsa, txo qis, thiab thauj khoom vertically. Lub peev xwm nqa ntawm lub crane nyob ntawm qhov specifications ntawm lub hoist lossis trolley siv.
Span thiab Qhov siab: Qhov ntev ntawm ib leeg girder gantry crane hais txog qhov kev ncua deb ntawm qhov chaw ntawm ob txhais ceg. Qhov siab ntawm lub crane yog txiav txim los ntawm qhov yuav tsum tau nqa qhov siab thiab clearance xav tau rau lub load. Cov qhov ntev no tuaj yeem hloov kho raws li kev thov tshwj xeeb thiab qhov chaw txwv.
Mobility: Ib leeg girder gantry cranes tuaj yeem tsim nrog cov teeb tsa ruaj khov lossis txawb. Tsau gantry cranes raug ntsia mus tas li nyob rau hauv ib qho chaw tshwj xeeb, thaum mobile gantry cranes tau nruab nrog lub log lossis lem, tso cai rau lawv txav mus rau hauv thaj chaw uas tau hais tseg.
Tswj System: Ib leeg girder gantry cranes yog ua los ntawm kev tswj hwm uas muaj xws li laub-khawm pendant tswj lossis chaw taws teeb tswj. Cov tshuab no ua rau cov neeg ua haujlwm tswj hwm lub crane txav, suav nrog kev nqa, txo qis, thiab hla lub nra.
Ib leeg girder gantry cranes paub txog lawv txoj kev siv ntau yam, yooj yim ntawm kev teeb tsa, thiab kev siv nyiaj zoo. Lawv haum rau ntau yam kev siv uas nruab nrab mus rau hnyav loads yuav tsum tau nqa thiab thauj horizontally. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xav txog yam xws li lub peev xwm thauj khoom, lub voj voog lub luag haujlwm, thiab ib puag ncig ib puag ncig thaum xaiv thiab ua haujlwm ib leeg girder gantry crane kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Tsis tas li ntawd, cov kev tswj xyuas siv nyob rau hauv ib leeg girder gantry cranes ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm crane. Nov yog qee qhov tseem ceeb ntawm cov kev tswj hwm no:
- Pendant Controls: Pendant tswj yog ib qho kev tswj kev xaiv rau ib leeg girder gantry cranes. Lawv muaj xws li ib tug handheld pendant chaw nres tsheb txuas nrog lub crane los ntawm ib tug cable. Qhov chaw nres tsheb pendant feem ntau suav nrog cov nyees khawm lossis cov keyboards uas tso cai rau tus neeg teb xov tooj los tswj ntau yam crane txav, xws li nqa, txo qis, trolley traverse, thiab choj mus ncig. Pendant tswj muab qhov yooj yim thiab intuitive interface rau tus neeg teb xov tooj los tswj lub crane txav.
- Xov tooj cua tswj chaw taws teeb: Xov tooj cua chaw taws teeb tswj tau nrov zuj zus nyob rau hauv niaj hnub crane tswj systems. Lawv muab qhov zoo ntawm kev tso cai rau tus neeg teb xov tooj los tswj lub crane txav ntawm qhov chaw nyab xeeb, muab kev pom zoo dua thiab yooj yim. Xov tooj cua tej thaj chaw deb tswj muaj ib tug handheld transmitter uas xa cov teeb liab wirelessly mus rau lub crane lub receiver unit. Lub transmitter yog nruab nrog cov nyees khawm lossis joysticks uas rov ua dua cov haujlwm muaj nyob ntawm pendant tswj.
- Cabin Controls: Hauv qee qhov kev siv, ib leeg girder gantry cranes yuav nruab nrog tus neeg tsav tsheb alarm. Lub alarm muab ib puag ncig kev ua haujlwm rau tus neeg tsav tsheb crane, tiv thaiv lawv los ntawm cov khoom sab nraud thiab muab kev pom zoo dua. Lub kaw lus tswj nyob rau hauv lub alarm feem ntau muaj xws li ib tug tswj vaj huam sib luag nrog cov nyees khawm, keyboards, thiab joysticks khiav lub crane txav.
- Variable Frequency Drives (VFD): Variable zaus drives feem ntau siv nyob rau hauv kev tswj ntawm ib leeg girder gantry cranes. VFDs tso cai rau kev tswj kom du thiab meej ntawm crane lub cev muaj zog ceev, ua kom nrawm nrawm thiab txo qis. Cov yam ntxwv no txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm lub crane txav, txo qhov hnav thiab tsim kua muag ntawm cov khoom thiab txhim kho kev tswj hwm.
- Kev Nyab Xeeb Nta: Tswj cov tshuab rau ib leeg girder gantry cranes suav nrog ntau yam kev nyab xeeb. Cov no tuaj yeem suav nrog cov khawm nres thaum muaj xwm txheej ceev, lub tshuab tiv thaiv overload, txwv cov keyboards kom tiv thaiv kev hla dhau, thiab kev tiv thaiv kev sib tsoo kom tsis txhob muaj kev sib tsoo nrog cov teeb meem lossis lwm yam cranes. Cov yam ntxwv kev nyab xeeb no yog tsim los tiv thaiv ob tus neeg tsav tsheb crane thiab ib puag ncig ib puag ncig.
- Automation thiab Programmability: Kev tswj hwm qib siab rau ib leeg girder gantry cranes tuaj yeem muab cov peev txheej automation thiab programmability. Qhov no tso cai rau cov creation ntawm pre-set lifting sequences, meej load positioning, thiab kev koom ua ke nrog rau lwm yam systems los yog txheej txheem.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev tswj xyuas tshwj xeeb siv nyob rau hauv ib qho girdergantry cranetuaj yeem sib txawv nyob ntawm qhov chaw tsim khoom, qauv, thiab kev xaiv kho kom haum. Lub kaw lus tswj yuav tsum raug xaiv raws li cov kev xav tau ntawm kev ua haujlwm, kev xav txog kev nyab xeeb, thiab kev nyiam ntawm tus neeg tsav tsheb crane.
