Kev kho dua tshiab ntawm lub choj crane yog qhov tseem ceeb rau kev ua kom nws ua haujlwm tau zoo thiab muaj kev nyab xeeb. Nws suav nrog kev tshuaj xyuas thiab kev saib xyuas cov khoom siv kho tshuab, hluav taws xob, thiab cov qauv. Nov yog cov ntsiab lus ntawm kev kho dua tshiab suav nrog:
1. Kev Kho Dua Tshiab
Cov khoom siv kho tshuab raug rhuav tshem tag nrho, suav nrog lub reducer, couplings, nruas sib dhos, log pawg, thiab cov khoom siv nqa. Cov khoom siv uas puas lawm lossis puas lawm raug hloov, thiab tom qab ntxuav kom huv si, lawv raug sib sau ua ke thiab muab roj nplua nyeem. Cov hlua hlau thiab nres kuj raug hloov thaum lub sijhawm no.
2. Kev Kho Dua Hluav Taws Xob
Lub tshuab hluav taws xob raug tshuaj xyuas tag nrho, nrog rau cov cav uas raug rhuav tshem, ziab, rov sib dhos, thiab muab roj nplua nyeem. Cov cav uas puas lawm raug hloov, nrog rau cov actuators nres thiab cov maub los uas tawg. Lub txee tiv thaiv raug kho lossis hloov pauv, thiab txhua qhov kev sib txuas xov hlau raug kuaj xyuas. Cov vaj huam sib luag tswj hwm teeb pom kev zoo thiab teeb liab kuj raug hloov pauv yog tias tsim nyog.
3. Kev Kho Dua Tshiab
Cov qauv hlau ntawm lub crane raug tshuaj xyuas thiab ntxuav. Lub beam tseem ceeb raug kuaj xyuas seb puas muaj qhov sagging lossis khoov. Yog tias pom muaj teeb meem, lub beam raug ncaj thiab txhawb nqa. Tom qab kho dua tshiab, tag nrho lub crane raug ntxuav kom huv si, thiab muaj ob txheej txheej tiv thaiv xeb.
Cov Txheej Txheem Scrapping rau Main Beam
Lub nqaj tseem ceeb ntawm lub crane muaj lub neej luv luv. Tom qab kho ntau zaus, yog tias lub nqaj qhia txog qhov poob qis lossis tawg, nws qhia txog qhov kawg ntawm nws lub neej ua haujlwm zoo. Lub chaw haujlwm kev nyab xeeb thiab cov tub ceev xwm yuav soj ntsuam qhov puas tsuaj, thiab lub crane yuav raug tshem tawm. Kev puas tsuaj los ntawm kev qaug zog, ua los ntawm kev ntxhov siab thiab kev hloov pauv ntau zaus dhau sijhawm, ua rau lub nqaj tsis ua haujlwm. Lub neej ua haujlwm ntawm lub crane sib txawv nyob ntawm nws hom thiab cov xwm txheej siv:
Cov cranes hnyav (piv txwv li, clamshell, grab cranes, thiab electromagnetic cranes) feem ntau kav ntev li 20 xyoo.
Cov cranes thauj khoom thiabtuav cov craneskav ntev li ntawm 25 xyoo.
Forging thiab casting cranes tuaj yeem kav ntev dua 30 xyoo.
Cov choj cranes dav dav tuaj yeem muaj lub neej ua haujlwm ntawm 40-50 xyoo, nyob ntawm seb muaj kev siv li cas.
Kev kho dua tshiab tsis tu ncua ua kom lub crane tseem muaj kev nyab xeeb thiab ua haujlwm tau zoo, ua rau nws lub neej ua haujlwm ntev dua thaum txo qis kev pheej hmoo cuam tshuam nrog cov khoom siv uas puas lawm.
