Kev ua haujlwm ntawm kev nqa nqa yog txiav txim siab los ntawm crawler cranes, uas ua haujlwm nyob rau hauv cov xwm txheej hnyav uas muaj cov khoom ntxhib, cov ntaub ntawv abrasive, thiab cov khoom hnyav. Yog li, cov khau taug qab yuav tsum tau hloov ntau zaus kom ntseeg tau tias kev ua haujlwm zoo ntawm crawler cranes.
Qhov tseem ceeb ntawm Kev Hloov Cov Khaub Ncaws Ntawm Crawler Cranes
Crawler crane taug qab nkawm khau, lossis cov ntaub qhwv, grousers, yog lub luag haujlwm nqa tag nrho qhov hnyav ntawm lub tshuab thiab muab kev sib cuag hauv av. Cov teeb meem tseem ceeb ntawm cov ntu no suav nrog:
Tshaj - hnav ntawm cov kab grouser
Kev tawg los yog khoov los ntawm kev cuam tshuam
Bolt qhov loj
Cov khau xoob vim poob ntawm qhov nro nro
Tsis saib xyuas qhov no yuav ua rau derailment, misalignment, thiab txawm tias kim kho cov saw txuas thiab sprockets.
Cov Cuab Yeej & Yam Koj Yuav Xav Tau
Ua ntej pib txheej txheem, nws yuav tsum muaj cov khoom hauv qab no:
Hloov cov khau khau (cov khoom qub lossis cov khoom siv sib xws)
Impact wrench/torque wrench
Qhov (socket) thiab breaker bar
Hydraulic khiav jack lossis crane txhawb nqa
Anti- txeeb teb chaws
Siab - lub zog bolts thiab ceev (qib 10.9 lossis siab dua)
PPE: hnab looj tes, steel- khau looj plab hlaub, looj tsom iav dub
Hloov cov khau ntawm Crane
Kauj Ruam 1: Kev Npaj Kev Nyab Xeeb
Nres lub crane rau ntawm qhov chaw tiaj tus thiab nyuaj.
Txuas tag nrho cov xauv kev nyab xeeb thiab tso tag nrho cov ntawv txuas rau hauv av.
Kaw lub cav thiab depressurize hydraulic kua.
Txhawb lwm txoj kev nrog cov blocks thiab cribbing lub crane lub cev.
Kauj Ruam 2: Nqa Txoj Kev
Siv lub hydraulic jack los tsa tus khiav kom nws cov khau raug tshem tawm hauv av. Xyuas kom meej tias cov chaw txhawb nqa tau teeb tsa kom zoo hauv qab tus ncej.
Kauj Ruam 3: Tshem Tawm Cov Khaub Ncaws Qub
Tshem cov bolts qub thiab cov txiv ntseej los ntawm kev cuam tshuam wrenches. Cov roj nkag tuaj yeem pab tshem tawm cov bolts tawv.
Xaub cov khau siv los ntawm cov saw txuas.
Kev tshuaj xyuas cov saw bushings, saw pins, thiab txuas txuas yuav tsum tau ua ua ntej txhim kho cov khau tshiab.
Kauj Ruam 4: Npaj cov khau tshiab
Kev siv cov tshuaj tiv thaiv- txeeb cov khoom sib xyaw rau cov bolts pab tiv thaiv kev sib tsoo rau yav tom ntej.
Xyuas kom meej tias cov khau qhov sib raug zoo nrog cov ntaub ntawv txuas.
Kauj ruam 5: Installation & Torquing
Mount cov bolts thiab ceev ntawm cov khau tshiab.
Tightening yuav tsum maj mam hla ntawm ib leeg nyob rau hauv ib qho kev sib tshuam.
Tus nqi torque yuav tsum tau kuaj xyuas siv lub torque wrench (500-800 Nm).
Kauj Ruam 6: Kev Tshawb Fawb Kawg
Rov ua dua rau txhua nkawm khau ntawm txoj kev ntawd.
Txo lub crane thiab tshem tawm cov kev txhawb nqa.
Kuaj txoj kev los ntawm kev maj mam tig mus rau pem hauv ntej thiab rov qab, mloog rau lub suab txawv txawv lossis tsis zoo.
Re-torque tag nrho cov bolts tom qab 1-2 teev ua haujlwm.
Tswv yim rau Extended Track Shoe Life
Sib pauv nkawm khau thaum siv abrasive (xws li xuab zeb thiab gravel).
Tshawb xyuas cov bolts xoob los ntawm kev sim torque txhua lub lim tiam - qhov no ua rau kom hnav.
Khaws cov ciav hlau kom huv si kom tshem tawm cov khib nyiab abrasive.
Ib txwm hloov nkawm khau hauv khub rau kev sib npaug.
