Underhung overhead cranes, tseem hu ua under-running or underslung cranes, yog ib hom kev siv nyiaj siv ua haujlwm crane uas raug tshem tawm ntawm lub tsev qauv saum toj no. Lawv feem ntau siv nyob rau hauv kev lag luam chaw qhov chaw hauv pem teb yog txwv los yog qhov chaw muaj teeb meem nyob rau hauv pem teb uas yuav cuam tshuam rau kev ua hauj lwm ntawm ib txwm overhead cranes. Nov yog qee yam ntawm cov khoom lag luam thiab cov yam ntxwv ntawm underhung overhead cranes:
Tsim thiab Kev Tsim Kho: Underhung overhead cranes feem ntau tsim nrog ib qho kev teeb tsa ib leeg, txawm hais tias ob chav girder tsim kuj muaj. Lub crane raug tshem tawm los ntawm lub tsev qauv siv cov tsheb thauj khoom kawg uas khiav ntawm txoj kab ciav hlau txuas nrog lub tsev txhawb nqa. Lub crane taug kev raws txoj kab ciav hlau khiav, tso cai rau kab rov tav txav ntawm lub nra.
Load Capacity: Underhung overhead cranes muaj nyob rau hauv ntau lub peev xwm thauj khoom kom haum rau kev thov sib txawv. Lub peev xwm thauj khoom tuaj yeem nyob ntawm ob peb puas kilograms mus rau ob peb tons, nyob ntawm seb tus qauv tshwj xeeb thiab tsim.
Span thiab Runway Length: Qhov ntev ntawm lub underhung crane hais txog qhov kev ncua deb ntawm cov kab ciav hlau khiav, thiab nws tuaj yeem sib txawv nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov. Ib yam li ntawd, qhov ntev ntawm txoj kev khiav yog txiav txim siab los ntawm qhov chaw muaj thiab thaj chaw uas xav tau.
Underhung nyiaj siv ua haujlwm cranes tau siv dav hauv ntau daim ntawv thov kev lag luam uas siv cov khoom siv tau zoo thiab qhov chaw optimization yog qhov tseem ceeb. Qee qhov kev siv rau underhung overhead cranes suav nrog:
Kev Tsim Khoom Siv: Cov cranes feem ntau yog siv rau hauv cov chaw tsim khoom rau kev ua haujlwm xws li txav cov khoom siv raw, cov khoom, thiab cov khoom tiav raws li cov kab sib dhos. Lawv kuj tuaj yeem siv rau kev thauj khoom thiab tshem tawm cov cav tov, hloov khoom nruab nrab ntawm cov chaw ua haujlwm, thiab ua kom yooj yim rau kev tuav cov khoom siv hauv qhov chaw.
Warehouses and Distribution Centers: Underhung cranes yog qhov zoo rau kev lag luam thiab chaw xa khoom. Lawv tuaj yeem txav tau zoo thiab tso cov khoom hauv qhov chaw, suav nrog kev thauj khoom thiab tshem tawm cov tsheb thauj khoom thiab cov thawv ntim khoom, npaj cov khoom muag, thiab thauj cov khoom mus rau thiab los ntawm cov chaw cia khoom.
Automotive Industry: Underhung cranes pom kev siv dav hauv kev lag luam tsheb, qhov chaw uas lawv tau ua haujlwm nyob rau hauv cov kab sib dhos, lub khw muag khoom, thiab cov rooj zaum pleev xim. Lawv pab hauv kev txav ntawm lub cev ntawm lub tsheb, qhov chaw, thiab cov khoom siv, txhim kho kev tsim khoom thiab ua kom cov txheej txheem ntau lawm.
Load Capacity thiab Overload Protection: Nws yog ib qho tseem ceeb los xyuas kom meej tias lub underhung crane tsis overloaded tshaj nws cov peev txheej. Overloading tuaj yeem ua rau kev ua haujlwm tsis zoo lossis crane tsis ruaj khov. Ib txwm ua raws li cov kev txwv lub peev xwm uas tau teev tseg los ntawm cov chaw tsim khoom. Tsis tas li ntawd, underhung cranes yuav tsum tau nruab nrog kev tiv thaiv overload, xws li load limiters lossis load cells, kom tsis txhob overloading.
Kev cob qhia kom raug thiab ntawv pov thawj: Tsuas yog cov neeg ua haujlwm tau txais kev cob qhia thiab muaj ntawv pov thawj yuav tsum tau ua haujlwm hauv cranes. Cov neeg ua haujlwm yuav tsum paub txog cov qauv crane tshwj xeeb, nws cov kev tswj hwm, thiab cov txheej txheem kev nyab xeeb. Kev cob qhia kom zoo pab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm, kev tuav pov hwm, thiab kev paub txog kev phom sij.
Kev tshuaj xyuas thiab kev tu: Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm underhung cranes yog qhov tseem ceeb rau kev txheeb xyuas thiab daws txhua yam teeb meem kev siv tshuab lossis kev hnav thiab tsim kua muag. Kev tshuaj xyuas yuav tsum suav nrog kev tshuaj xyuas qhov xwm txheej ntawm cov kab hluav taws xob khiav, cov tsheb thauj khoom kawg, lub tshuab hoist, cov tshuab hluav taws xob, thiab cov yam ntxwv ntawm kev nyab xeeb. Txhua yam tsis xws luag lossis qhov txawv txav yuav tsum tau kho tam sim lossis daws los ntawm cov neeg ua haujlwm tsim nyog.
