Dab tsi yog Cables Txuas Nrog Ob Chav Girder Choj Cranes?

Dab tsi Cables tau nruab nrog Ob Chav Girder Choj Cranes?

Ob chav-girder choj crane yog tsim los ntawm choj ncej, trolley kev khiav hauj lwm mechanism, trolley, khoom siv hluav taws xob, thiab lwm yam raws li qhov zaus ntawm kev siv, nws muab faib ua peb theem ua haujlwm: A5, A6 thiab A7. Tag nrho cov kev txav thiab kev tswj ntawm lubhook overhead craneua tiav nyob rau hauv lub rooj tsav tsheb. Lub ntsiab tsis tseem ceeb ntawm ob chav girder choj crane:

1. Lifting peev: 5-10 tons, 16/3.2 txog 50/10 tons, 75/20 txog 100/20 tons, 100/32 tons, 125/30 txog 250/50 tons, 300/40 tons, 350/75 400/80 tons, 600/150 tons

2. Ntev: 10.5 ~ 31.5 meters, 13 ~ 31 meters.

3. Lifting qhov siab: 6 ~ 22 meters.

Cable ib feem ntawm tus choj crane ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv choj crane. Qhov zoo ntawm kev ua haujlwm cable ncaj qha cuam tshuam seb lub crane tuaj yeem ua haujlwm li cas. Lub trolley mechanism thiab lifting mechanism yog ob qho tib si siv los ntawm kev xa xov hluav taws xob, yog li lub cable plays lub luag haujlwm raws li qhov txuas hauv kev ua haujlwm ntawm crane. Yog tias koj siv cable ntau dhau, koj yuav nkim nyiaj. Yog tias lub cable raug hlawv, nws tuaj yeem ua rau muaj kev nyab xeeb. Yog li yuav ua li cas xaiv txoj cai cable?

Lub cable loj ntawm ob-girder choj crane yog txiav txim los ntawm qhov tam sim no, uas muaj feem xyuam rau qhov voltage thiab tag nrho lub zog ntawm ob-girder choj crane. Piv txwv li, lub ntsiab fais fab mov ntawm ib tug 5-tuj ob-girder choj crane yog tsim los ntawm ob lub crane motors, ib tug trolley lub cev muaj zog thiab ib tug nqa lub cev muaj zog. Tag nrho lub zog ntawm lub tshuab ob-girder choj tuaj yeem suav ua 9.9kw. Qhov hluav taws xob siv yog 380V, yog li qhov tam sim no ntawm lub cable tuaj yeem suav ua 26 amps raws li cov qauv: lub zog=voltage * tam sim no. Qhov tam sim no uas ib square tooj liab tub ntxhais cable tuaj yeem kis tau li ntawm 7 amps, yog li 4 square cables yuav txaus siab 26 amps. Nws tuaj yeem pom tau tias peb yuav tsum nkag siab txog lub zog, qhov hluav taws xob, lub peev xwm nqa tam sim no ntawm cov kab hluav taws xob thiab qhov ceev ntawm ob lub cev muaj zog ob-girder choj crane.

Tsis tas li ntawd, kev xaiv cov cables yuav tsum xav txog cov npe loj ntawm kev ua lag luam. Qee lub tsev me me txiav cov ces kaum thaum tsim cov cables, uas qhia tau hais tias tsis muaj 4 square meters ntawm cable hauv 4 square meters. Cov tub ntxhais tooj liab ntawm qhov tsim nyog tooj liab hlau yuav tsum yog xim liab-liab, ci iab thiab mos. Txawm li cas los xij, cov xov hlau tsis zoo thiab tsis zoo yog xim liab-dub, lub teeb daj lossis xim dawb, muaj ntau yam impurities, tsis muaj zog txhua yam thiab tsis muaj zog. Lawv yuav tawg nrog me ntsis quab yuam, thiab cov xov hlau feem ntau tawg. Txhawm rau kuaj xyuas, tsuas yog tev tawm 2 centimeters ntawm ib kawg ntawm cov hlau thiab rub ib daim ntawv dawb ntawm cov tub ntxhais tooj liab. Yog tias muaj cov khoom dub rau ntawm daim ntawv dawb, nws txhais tau hais tias muaj cov impurities ntau dua hauv cov tub ntxhais tooj liab. Tsis tas li ntawd, txheej txheej rwb thaiv tsev ntawm cov xov hlau cuav zoo li tuab heev. Qhov tseeb, lawv feem ntau yog ua los ntawm cov yas rov ua dua tshiab. Nyob rau tib lub sijhawm, lub rwb thaiv tsev yuav muaj hnub nyoog thiab xau hluav taws xob.

Yog tiasfais fab mov cablentawm ob-girder choj crane yog xaiv tsis raug, nws yuav ua rau muaj kev nyab xeeb. Ib lub cable yuav me me, tab sis nws muaj lub luag haujlwm loj. Ntau qhov hluav taws kub yog tshwm sim los ntawm kev laus hluav taws xob thaiv hluav taws xob, cov khoom siv tsis raug, lossis cov xaim tsis zoo. Yog li ntawd, cov neeg siv yuav tsum ua kom pom tseeb thiab txheeb xyuas kom zoo thaum xaiv, txhawm rau txhawm rau teeb meem hauv pob.
