Hauv kev siv txhua hnub, choj cranes yuav tsum tau soj ntsuam kev phom sij tsis tu ncua kom ntseeg tau tias cov khoom siv ua haujlwm nyab xeeb. Hauv qab no yog cov lus qhia ntxaws ntxaws rau kev txheeb xyuas qhov muaj peev xwm txaus ntshai hauv choj cranes:
1. Kev tshuaj xyuas txhua hnub
1.1 Cov cuab yeej zoo li
Tshawb xyuas tag nrho cov tsos ntawm crane kom paub tseeb tias tsis muaj kev puas tsuaj lossis deformation.
Tshawb xyuas cov khoom siv (xws li cov kab teeb tseem ceeb, cov kab hluav taws xob kawg, cov kab txhawb nqa, thiab lwm yam) rau cov kab nrib pleb, corrosion, lossis weld tawg.
1.2 Lifting Appliances thiab Hlau Ropes
Txheeb xyuas qhov hnav ntawm cov hooks thiab cov cuab yeej nqa kom ntseeg tau tias tsis muaj kev hnav ntau dhau lossis deformation.
Txheeb xyuas qhov hnav, tawg, thiab lubrication ntawm cov hlua hlau steel kom paub tseeb tias tsis muaj qhov hnyav hnyav lossis tawg.
1.3 Khiav khiav
Txheeb xyuas qhov ncaj thiab kho ntawm txoj kab kom paub tseeb tias nws tsis xoob, deformed, lossis hnyav hnyav.
Ntxuav cov khib nyiab ntawm txoj kev taug thiab xyuas kom tsis muaj kev cuam tshuam ntawm txoj kev.
2. Mechanical system soj ntsuam
2.1 Lifting mechanism
Xyuas cov nres, winch, thiab pulley pab pawg ntawm lub lifting mechanism kom paub meej tias lawv ua hauj lwm ib txwm thiab lubricated zoo.
Txheeb xyuas qhov hnav ntawm tus nres kom paub meej tias nws ua haujlwm tau zoo.
2.2 Transmission system
Xyuas cov iav, chains, thiab siv nyob rau hauv lub kis tau tus mob system kom paub tseeb tias tsis muaj ntau dhau hnav los yog looseness.
Xyuas kom meej tias lub kaw lus kis tau zoo lubricated thiab tsis muaj suab nrov lossis kev vibrations.
2.3 Trolley thiab Choj
Tshawb xyuas kev ua haujlwm ntawm kev nqa lub trolley thiab tus choj kom ntseeg tau tias kev txav mus los thiab tsis muaj kev cuam tshuam.
Txheeb xyuas qhov hnav ntawm cov log tsheb thiab cov lem ntawm lub tsheb thiab tus choj kom paub tseeb tias tsis muaj qhov hnyav hnyav.
3. Kev tshuaj xyuas hluav taws xob
3.1 Cov khoom siv hluav taws xob
Tshawb xyuas cov khoom siv hluav taws xob xws li cov txee tswj, lub cev muaj zog, thiab cov tshuab hloov zaus kom ntseeg tau tias lawv ua haujlwm zoo yam tsis muaj cua sov lossis tsw ntxhiab.
Xyuas cov cable thiab xaim kom paub tseeb tias lub cable tsis puas, laus, lossis xoob.
3.2 Tswj system
Ntsuam xyuas ntau yam kev ua haujlwm ntawm kev tswj xyuas kom ntseeg tau tias kev nqa, lateral, thiab longitudinal ua haujlwmnyiaj siv ua haujlwm craneyog li qub.
Tshawb xyuas cov kev txwv hloov pauv thiab cov cuab yeej nres thaum muaj xwm ceev kom paub tseeb tias lawv ua haujlwm zoo.
4. Kev tshuaj xyuas cov cuab yeej kev nyab xeeb
4.1 Kev tiv thaiv overload
Xyuas cov khoom tiv thaiv overload kom ntseeg tau tias nws tuaj yeem ua haujlwm tau zoo thiab teeb tsa lub tswb thaum overloaded.
4.2 Anti kev sib tsoo ntaus ntawv
Xyuas cov cuab yeej tiv thaiv kev sib tsoo thiab txwv cov cuab yeej kom ntseeg tau tias lawv tuaj yeem tiv thaiv kev sib tsoo crane thiab overstepping.
4.3 Thaum muaj xwm ceev braking
Ntsuam xyuas lub kaw lus thaum muaj xwm ceev los xyuas kom meej tias nws tuaj yeem nres kev ua haujlwm ntawm crane sai sai thaum muaj xwm txheej ceev.
