Hauv kev lag luam crane, xaiv nruab nrab ntawm aKuj tsis paub meej zaus lub cev muaj zogthiab aOb-lub cev muaj zogTsis yog hais txog yuav ua li cas meej txog kev ua haujlwm yog-nws ncaj qha khi rau cov tsis zoo li crane lub peev nyiaj thiab hoist qhov siab. Cia peb tsoo nws nrog cov xwm txheej tiag tiag.
Ua ntej, xav txog kev nqa lub peev xwm. Feem ntau, rau cov cranes me me nyob rau hauv 5 tons-zoo li cov siv hauv kev nqa khoom pwm lossis hauv cov tsev muag khoom los hloov cov thawv-ob-lub zog ua kom nrawm dua. Vim li cas? Cov cav tov no coj lub teeb lub teeb, thiab lawv tsuas yog xav tau ob txoj haujlwm: ib ncig ntawm 5 metre (ib ncig 15 metres ib feeb) kom txav mus ua tiav txoj haujlwm sai dua. Lub "ob lub zog" ntawm ob-nrawm lub cev muaj zog haum no, thiab lawv tsis tas yuav muaj ib nrab ntawm ib feem ntau zaus ua haujlwm teeb tsa, yog li tsis tas yuav tsum tau saib xyuas cov khoom me me.
Tab sis thaum nws los txog rau nruab nrab thiab loj cranes tshaj 10 tons, tshwj xeeb tshaj yog 20 tons thiab saum toj,Cov Hluav Taws Xob Ntau Cov Motorsfeem ntau yog yuav tsum. Nqa cov chaw nres nkoj cranes (feem ntau 30-50 tons) lossis kev tsim kho cranes nqa cov qauv hlau (25+ tons), piv txwv. Cov cav tov coj hnyav, muaj txiaj ntsig, thiab txawm tias lub viav vias me me tuaj yeem ua teeb meem. Cov khoom siv sib txawv zaus muaj peev xwm kho tau nrawm nrawm los ntawm 1 meter ib feeb mus rau 20 meters ib feeb. Thaum nqa ib lub taub ntim, piv txwv li, lawv tuaj yeem qeeb maj los ntawm 15 metres ib feeb mus rau 2 metres ib feeb thaum lawv mus rau hauv lub hom phiaj, kom nres lub hom phiaj. Ib lub cev muaj zog ob lub cev muaj zog, hloov kom sai ntawm qhov siab kom ceev nrog lub nra hnyav nrog lub nra hnyav, yuav ua rau viav vias zoo.
Tom ntej no, hoisting qhov siab tseem ceeb heev. Rau qhov siab nyob rau hauv 10 metres-li rhiav rhiav cranes, qhov twg qhov kev ncua deb ntawm ob lub zog tsis yog qhov teeb meem loj me me tsis yog qhov teeb meem loj, yog li lawv ua haujlwm zoo. Tab sis rau cov cuab yeej xws li chaw nres nkoj gantry cranes (nrog hoisting qhov siab tshaj 40 meters) lossis kuv cov hoists (nrog qhov siab ncav ntau pua ntawm cov meters),Cov Hluav Taws Xob Ntau Cov Motorsyog qhov tseem ceeb. Ntawm qhov siab siab, lub viav vias ntawm lub nra muaj tau nthuav tawm. Ib ob-nrawm lub cev muaj zog "iav-dhia" nrawm hloov tuaj yeem ua viav vias ntau metres, uas yog qhov pheej hmoo ntau dhau. Cov khoom siv sib txawv zaus cov motors, ntawm qhov tod tes, kev tswj hwm los ntawm 40 metres siab ntawm tsuas yog 0.5 metres ib feeb, khaws nws khov kho tag nrho lub sijhawm.
Lwm qhov kev ntsuas tseem ceeb yog lub luag haujlwm ntawm chav kawm. Cranes tau ntsuas los ntawm A1 rau A8, muaj cov chav kawm siab dua ntau dua (A6 thiab saum toj, ua haujlwm tsis tu ncua rau}}} teev ib hnub). Rau cov kev ua haujlwm siab-zoo li cranes hauv hlau mills Lifting Hlau (A7 chav kawm) -Txhua yog tias muaj peev xwm loj heev (hais 15 tons),Cov Hluav Taws Xob Ntau Cov Motorsyog qhov tsim nyog. Ob-lub zog ceev, nrog lawv cov iav ua haujlwm nquag, zoo li muaj ntau dua thiab muaj hnub nyoog sab hauv cov coils sai sai, ua rau kev kho kom nquag. Ntau zaus zaus lub cev muaj zog, txawm li cas los xij, tsis tshua muaj cua sov ua haujlwm tau yooj yim-lawv lub neej feem ntau yog ob npaug ntawm ob-ceev cov motors.
Hauv ntej: rau cov peev xwm me me (qis dua 5 tons), qis dua (hauv qab), thiab qis dua), ob-ceev cov motors muaj tus nqi zoo tshaj plaws. Rau cov muaj peev xwm loj (ntau dua 10 tons), siab siab (ntau tshaj 20 metres ua haujlwm, lossis txhawb kev tsim nyog / hnyav thauj khoom,Cov Hluav Taws Xob Ntau Cov Motorsmuaj kev ntseeg siab, kom muaj kev nyab xeeb thiab kev ua tau zoo.
