Cov cranes saum toj kawg nkausyog cov khoom siv tseem ceeb hauv kev tsim khoom lag luam, kev xa khoom, thiab kev tsim kho, nrog rau kev tsim qauv ib-girder thiab ob-girder yog ob hom feem ntau. Kev xaiv qhov yog cuam tshuam ncaj qha rau kev ua haujlwm zoo, kev nyab xeeb, thiab kev siv nyiaj mus sij hawm ntev.
1. Cov Kev Cai Rau Qhov Muaj Peev Xwm Thauj Khoom
Lub peev xwm thauj khoom yog qhov tseem ceeb tshaj plaws rau kev xaiv crane.
Cov Cranes Ib Leeg Girder Overhead: Feem ntau tsim los rau cov khoom thauj me me mus rau nruab nrab, feem ntau yog txij li 0.5 tons txog 20 tons. Lawv cov qauv yooj yim txwv tsis pub muaj peev xwm thauj khoom, ua rau lawv tsis haum rau kev ua haujlwm hnyav.
Ob Chav Girder Overhead Cranes: Zoo heev rau cov xwm txheej hnyav, nrog rau lub peev xwm feem ntau yog 5 tons txog ntau dua 500 tons. Lub qauv ob chav girder faib qhov hnyav sib npaug ntau dua, muab kev ruaj khov dua thiab muaj peev xwm thauj khoom rau kev tsim khoom hnyav lossis kev thauj khoom hauv chaw nres nkoj.
2. Kev Nyuaj Siab ntawm Cov Qauv thiab Qhov Chaw Xav Tau
Qhov sib txawv ntawm cov qauv cuam tshuam rau kev teeb tsa, kev saib xyuas, thiab kev siv qhov chaw.
Cov Cranes Ib Leeg: Muaj ib lub nqaj loj uas txhawb nqa los ntawm cov tsheb thauj khoom kawg. Lawv muaj tus qauv tsim me me, xav tau qhov chaw tsawg dua (qhov chaw ntsug) thiab qhov dav dav, thiab yooj yim dua rau kev teeb tsa thiab tswj. Cov qauv yooj yim kuj txo qhov xav tau kev txhawb nqa lub hauv paus nyuaj.
Ob Chav Girder Cranes: Muaj ob lub beams loj sib luag, nrog rau lub hoist (lub tshuab nqa) feem ntau khiav ntawm cov girders. Tus qauv tsim no xav tau ntau chav taub hau thiab qhov chaw kab rov tav. Kev teeb tsa cuam tshuam nrog kev sib dhos nyuaj dua ntawm ob lub girders, thiab kev saib xyuas yuav xav tau kev nkag mus rau thaj chaw ntawm cov beams, ua rau kev ua haujlwm nyuaj dua.
3. Cov Xwm Txheej Thov thiab Lub Voj Voog Ua Haujlwm
Qhov kev siv thiab zaus ua haujlwm (lub voj voog ua haujlwm) txiav txim siab seb hom crane twg haum tshaj plaws.
Cov Cranes Ib Leeg: Zoo tagnrho rau cov voj voog ua haujlwm qis mus rau nruab nrab (piv txwv li, cov chav kawm ua haujlwm A3-A5 raws li cov qauv ISO). Cov ntawv thov feem ntau suav nrog cov chaw ua haujlwm me me, cov tsev rau khoom, thiab cov kab sib dhos rau cov haujlwm xws li tsa cov khoom me me, ntim khoom, lossis sib dhos sib dhos - qhov twg cov khoom thauj sib dua thiab kev ua haujlwm tsis txuas ntxiv.
Cov Cranes Ob Chav Girder: Haum rau cov voj voog ua haujlwm siab (chav kawm ua haujlwm A6-A8) thiab thaj chaw nyuaj. Lawv siv dav hauv cov chaw tsim hlau (rau kev tsa cov hlau yaj), kev tsim tshuab hnyav (rau kev sib sau ua ke cov khoom siv loj), thiab cov chaw nres nkoj thawv (rau kev thauj khoom/tso cov thawv hnyav). Lawv cov qauv ruaj khov tiv taus kev siv ntau zaus, txuas ntxiv mus thiab cov xwm txheej hnyav xws li kub siab lossis hmoov av.
4. Kev Xav Txog Tus Nqi
Tus nqi suav nrog kev nqis peev thawj zaug, kev ua haujlwm, thiab kev saib xyuas.
Cov Cranes Ib Leeg: Muaj cov nqi yuav khoom thiab kev teeb tsa qis dua vim lawv cov qauv yooj yim. Cov nqi kho kuj qis dua, vim tias tsawg dua cov khoom yuav tsum tau kuaj xyuas lossis hloov. Lawv yog qhov kev xaiv pheej yig rau cov lag luam uas muaj peev nyiaj tsawg thiab cov kev xav tau me me.
Ob Chav Girder Cranes: Yuav tsum muaj cov nqi pib siab dua, suav nrog kev tsim khoom, kev teeb tsa, thiab kev txhawb nqa lub hauv paus. Txawm li cas los xij, lawv lub zog thiab lub peev xwm thauj khoom siab txo lub sijhawm tsis ua haujlwm hauv kev ua haujlwm hnyav, ua rau muaj kev rov qab los ntawm kev nqis peev (ROI) mus sij hawm ntev rau cov lag luam uas muaj kev thov thauj khoom hnyav tas mus li. Cov nqi txij nkawm siab dua tab sis raug cai los ntawm lawv lub neej ua haujlwm ntev thiab kev ntseeg siab.
5. Cov Lus Qhia Txog Cov Kauj Ruam Xaiv
Txhais Cov Kev Cai Rau Kev Thauj Khoom: Paub meej tias qhov thauj khoom siab tshaj plaws, qhov nruab nrab ntawm qhov thauj khoom, thiab qhov siab uas xav tau—qhov no yuav txiav txim siab seb puas siv tau ib lub girder (≤20 tons) lossis ob lub girder (>20 tons).
Soj Ntsuam Ib Puag Ncig Ua Haujlwm thiab Lub Voj Voog Ua Haujlwm: Yog tias kev ua haujlwm tas mus li, hnyav, lossis nyob rau hauv qhov xwm txheej hnyav, ob lub crane-girder yog qhov zoo dua; rau kev siv me me, tsis tu ncua, ib lub crane-girder txaus.
Tshuaj Xyuas Qhov Chaw Txwv: Xyuas seb puas muaj qhov chaw dav thiab qhov dav uas siv tau—cov cranes ib lub girder zoo dua rau qhov chaw nqaim, thaum cov cranes ob lub girder xav tau chaw ntau dua.
Tshuaj Xyuas Tus Nqi piv rau ROI: Rau lub sijhawm luv luv, kev xav tau siv me me, xaiv lub crane ib-girder kom txuag tau cov nqi; rau lub sijhawm ntev, kev ua haujlwm hnyav, nqis peev rau hauv ob-girder crane kom ntseeg tau zoo dua thiab ROI.
Xaus lus, tsis muaj ib txoj kev daws teeb meem uas "ib qho loj-haum-txhua tus". Kev xaiv nyob ntawm kev ntsuam xyuas tag nrho ntawm qhov hnyav, qhov chaw, kev siv, thiab tus nqi. Kev sab laj nrog cov tuam txhab tsim crane lossis cov engineers los ua qhov kev tshuaj xyuas tshwj xeeb ntawm qhov chaw tuaj yeem ua kom ntseeg tau tias lub crane xaiv tau ua raws li cov kev xav tau ua haujlwm thiab cov qauv kev nyab xeeb.
