Cov khoom siv ua haujlwm yog cov khoom siv tseem ceeb rau kev nqa cov khoom hnyav los tiv thaiv cov khoom siv hluav taws xob hnyav los tiv thaiv kev ua haujlwm ntawm cov nyiaj siv ua haujlwm ntawm cov neeg siv nyiaj ua ntej (}}
Lub peev xwm muaj peev xwm ntawm kev siv nyiaj ua haujlwm li cas?
Lub peev xwm thauj tau ntawm overhead crane yog feem ntau ua haujlwm txhawb nqa thiab muaj peev xwm txiav tawm los ntawm ob peb tons .
Qhov tseem ceeb ntawm kev nkag siab siv nyiaj ua ntej crane load muaj peev xwm
Paub lub peev xwm ntawm cov neeg ua haujlwm ua haujlwm yog qhov tseem ceeb tuaj yeem ua rau lub crane kom ua rau cov neeg ua haujlwm puas tuaj yeem ua rau muaj peev xwm ua rau cov neeg ua haujlwm puas tuaj yeem ua rau muaj kev phom sij, thiab muaj peev xwm qeeb, thiab muaj peev xwm qeeb ntxiv .
Tsis tas li ntawd, kev paub cov peev txheej ntawm ETO Crane pab txiav txim siab cov haujlwm uas tsis muaj txiaj ntsig, thiab cov kev nyab xeeb thiab kev nyab xeeb thiab poob nyiaj .
Muab xam los ntawm cov thauj khoom-muaj peev xwm muaj peev xwm ntawm choj Cranes
Txhawm rau laij cov peev txheej ntawm cov nyiaj siv ua haujlwm CRANE, koj yuav tsum paub plaub qhov tseem ceeb:
1,Crane span: CRANE SPAN yog qhov kev ncua deb ntawm cov chaw ntawm ob lub Trolleys txhawb tus choj . nws yog ntsuas los ntawm kev tsheb nqaj hlau rau kev tsheb nqaj hlau .
2,Choj qhov hnyav (suav nrog trolley thiab hoist):Qhov hnyav ntawm cov neeg siv nyiaj ua haujlwm suav nrog qhov hnyav ntawm cov nqaj, trolley thiab ho nrhiav tau cov ntaub ntawv no hauv crane {.
3,Ntau tshaj Log Load: Lub log ntau tshaj plaws thauj tau yog qhov hnyav tshaj plaws uas txhua lub log tau txhawb nqa hauv lub crane tus nqi no txhais tes {}}
4,Deflect: Deflection yog tus nqi ntawm khoov uas tshwm sim hauv cov qauv crane uas muaj nyob rau hauv lub chaw ntim khoom thaum nws tau txwv rau 1/600 ntawm kev ncua {}}
Thaum koj muaj cov txiaj ntsig zoo, koj tuaj yeem suav cov peev xwm ntawm koj cov nyiaj siv ua haujlwm siv cov qauv hauv qab no:
Thauj muaj peev xwm=(ntau tshaj log load x tus log) + qhov hnyav hnyav / (SPAN / 800) - DEFLECTION
Piv Txwv Kev Xam
Xav tias koj EOT Crane muaj cov lus qhia tshwj xeeb hauv qab no:
Crane Chaport: 25 Taw
Choj qhov hnyav (suav nrog trolley thiab crane): 12, {{1} patt
Lub log siab tshaj plaws thauj khoom: 10, {{1} phaus
Deflection: 0.04 nti
Siv cov qauv saum toj no, peb tuaj yeem suav nws lub peev xwm thauj khoom raws li hauv qab no:
Ter muaj peev xwm=(10, {lbs {lbs}}} lbs} lbs} lbs}}}}} 04 hauv.
Thauj muaj peev xwm=80, {l lbs} lbs} lbs} lbs} lbs} 03125 ft) - 0.04 hauv.
Muaj peev xwm=2, 560, 000 lbs - 12, {} lbs / 0}} 03125 ft.
Thauj khoom muaj peev xwm=2, 560, 000 lbs - 384, {lbs} lbs
Thauj muaj peev xwm=2, 176, 000 lbs
Yog li, lub peev xwm muaj peev xwm ntawm cov nyiaj siv ua ntej no yog 2,176, {{lbs} lbs.
Yam cuam tshuam rau lub nra ntawm choj Cranes
Crane span
Ib qho tseem ceeb tshaj plaws cuam tshuam rau cov khoom siv thauj khoom ntawm cov kab crane yog txhais tau tias cov neeg siv nyiaj ntau dua ntawm cov neeg siv nyiaj ntau tshaj plaws yog txiav txim siab los ntawm cov tsis muaj zog tivthaiv System .
Nuv qhov siab
Ib qho tseem ceeb tshaj plaws uas cuam tshuam rau lub peev xwm thauj khoom ntawm cov nyiaj siv ua haujlwm hauv qab ntawm lub zog hauv qab ntawm cov hwv kom deb li, nws yog qhov tseem ceeb hauv qab ntawm tus nuv thaum xaiv lub peev xwm hauv qab rau ib qho tshwj xeeb Daim ntawv thov .
Lub Luag Haujlwm Ncig Ua Si
The duty cycle of an overhead crane refers to the ratio of the time it is used to lift loads to the time it is idle. Cranes with higher duty cycles are designed for continuous lifting and moving, while cranes with lower duty cycles are intended for intermittent use. Selecting a crane with the proper duty cycle is critical to ensuring it can handle the demands of the job at hand without ua ntej hnav lossis tsis ua hauj lwm .
Tsim thiab Siv Cranes
Qhov loj me thiab cov duab ntawm lub crane, raws li nws cov khoom siv tshuab, txiav txim siab} Tus qauv tsim nyog qhia kom meej txog kev ua lag luam ntau tshaj plaws lossis ua rau muaj kev cuam tshuam rau kev ua haujlwm .
huab cua
Ib puag ncig uas ib qho kev siv nyiaj ua ntej yog siv kuj tuaj yeem pab kom muaj kev ua kom tau kub thiab txo cov khoom muaj zog thiab muaj peev xwm ua kom muaj kev nyab xeeb thiab ua haujlwm kom muaj kev nyab xeeb thiab ua haujlwm kom zoo rau lub sijhawm ntev .
