Kev txhim kho tus choj crane yog qhov tseem ceeb rau kev ua kom nws ruaj ntseg thiab ua haujlwm tau zoo. Nws suav nrog kev tshuaj xyuas kom ntxaws thiab kev saib xyuas cov khoom siv kho tshuab, hluav taws xob, thiab cov khoom siv. Nov yog cov ntsiab lus ntawm qhov kev kho dua tshiab suav nrog:
1. Mechanical Overhaul
Cov khoom siv tshuab yog disassembled tag nrho, nrog rau cov reducer, couplings, nruas sib dhos, pawg log, thiab cov cuab yeej nqa. Cov khoom uas puas los yog puas yog hloov, thiab tom qab kev tu kom huv si, lawv tau rov ua dua thiab lubricated. Cov hlau hlua hlau thiab cov brakes kuj tau hloov thaum lub sijhawm ua haujlwm no.
2. Hluav taws xob overhaul
Lub tshuab hluav taws xob tau ua tiav kev tshuaj xyuas, nrog cov motors disassembled, qhuav, reassembled, thiab lubricated. Txhua lub cev muaj zog raug hloov pauv, nrog rau cov nres nres nres thiab cov tswj hwm. Lub txee tiv thaiv yog kho los yog hloov, thiab tag nrho cov kev sib txuas txuas tau raug kuaj xyuas. Lub teeb pom kev zoo thiab teeb pom kev zoo tswj vaj huam sib luag kuj tseem hloov yog tias tsim nyog.
3. Kev kho dua tshiab
Cov qauv hlau ntawm lub crane raug tshuaj xyuas thiab ntxuav. Lub ntsiab nqaj yog kuaj xyuas seb puas muaj sagging lossis dabtsi yog khoov. Yog tias pom muaj teeb meem, lub nqaj yog straightened thiab ntxiv dag zog. Tom qab lub overhaul, tag nrho cov crane yog huv si, thiab ib tug tiv thaiv xeb txheej yog siv nyob rau hauv ob txheej.
Scraping Standards rau Main Beam
Lub ntsiab nqaj ntawm lub crane muaj lub neej ntev. Tom qab ntau qhov kev kho dua tshiab, yog tias lub teeb pom kev zoo sagging lossis tawg, nws qhia txog qhov kawg ntawm nws lub neej ua haujlwm nyab xeeb. Lub chaw saib xyuas kev nyab xeeb thiab cov kws tshaj lij yuav tshuaj xyuas qhov kev puas tsuaj, thiab lub crane yuav raug tshem tawm. Kev puas tsuaj los ntawm kev qaug zog, tshwm sim los ntawm kev ntxhov siab thiab deformation dhau sijhawm, ua rau lub teeb pom kev tsis zoo. Lub neej kev pab cuam ntawm lub crane txawv nyob ntawm seb nws hom thiab kev siv tej yam kev mob:
Cov cranes hnyav (piv txwv li, clamshell, grab cranes, thiab electromagnetic cranes) feem ntau kav 20 xyoo.
Loading cranes thiabnqa craneskav ib ncig ntawm 25 xyoo.
Forging thiab casting cranes tuaj yeem kav ntev dua 30 xyoo.
General choj cranes tuaj yeem muaj kev pab cuam lub neej ntawm 40-50 xyoo, nyob ntawm qhov kev siv.
Kev kho dua tshiab kom ntseeg tau tias lub crane tseem muaj kev nyab xeeb thiab ua haujlwm tau zoo, txuas ntxiv nws lub neej ua haujlwm thaum txo qis kev pheej hmoo cuam tshuam nrog cov khoom siv hnav.
