Cov tsheb ntiag tug uas nce ntxiv hauv cov nroog tau ua rau qhov sib txawv ntawm kev muab chaw nres tsheb thiab kev xav tau chaw nres tsheb tob zuj zus. Cov chaw nyob qub ntsib qhov chaw nres tsheb tsis txaus, cov chaw lag luam qeeb qeeb, thiab cov chaw ntiag tug tsis muaj chaw rau ntau lub tsheb. Kev nres tsheb ib txwm tsis tuaj yeem ua tau raws li cov kev xav tau niaj hnub no, ua rau muaj kev cuam tshuam rau kev txhim kho tsheb khiav hauv nroog. Txhawm rau daws cov teeb meem no, ib tiam tshiab ntawm "plaub-ncej yooj yim hydraulic chaw nres tsheb" tau tso tawm, ua ke kev tsim kho zoo, kev ua haujlwm hydraulic ruaj khov, cov yam ntxwv kev nyab xeeb tag nrho, thiab kev teeb tsa yooj yim ua qhov kev xaiv zoo tshaj plaws rau kev hloov kho chaw nres tsheb hauv tsev, lag luam, thiab pej xeem.
Tsim los ntawm kev siv thev naus laus zis uas tau ua pov thawj lawm, lub kaw lus no siv "lub tshuab tsav hydraulic-wire rope", tshem tawm cov khoom siv nyuaj. Nws ua haujlwm tau zoo nrog kev pib thiab nres maj mam, kev co tsawg, thiab kev ua haujlwm ntsiag to. Siv hluav taws xob tsawg thiab tsis tas yuav saib xyuas ntau, nws ua tau zoo dua li cov khoom siv nres tsheb loj. Nws tus qauv me me plaub-ncej txuag qhov chaw yam tsis thaiv kev taug kev. Kev teeb tsa tsis tas yuav ua haujlwm loj, ua rau kev teeb tsa thiab kev ua haujlwm sai sai. Hauv lub sijhawm luv luv, qhov chaw nres tsheb tuaj yeem nce ob npaug, sib npaug ntawm kev siv tau thiab kev hloov pauv ntawm qhov chaw.
Ua raws li cov qauv zoo nruj, lub cev tseem ceeb thiab cov khoom siv thauj khoom siv cov hlau zoo. Cov phaj tseem ceeb yog tuab thiab ua kom raug rau kev tiv thaiv zoo heev rau kev hloov pauv, kev laus, thiab kev xeb. Txawm tias muaj ntau zaus nqa, cov qauv tseem ruaj khov thiab siv tau ntev. Cov platform tiv thaiv kev plam tiv thaiv lub tsheb swb thaum nres tsheb thiab nqa. Tsim los rau cov tsheb thauj neeg txhua qhov loj me, nws ua kom muaj kev nyab xeeb thiab ruaj khov nkag mus rau hauv lub tsheb txhua lub sijhawm.
Kev nyab xeeb yog qhov tseem ceeb ntawm kev tsim qauv. Lub kaw lus no muaj "kev tiv thaiv kev nyab xeeb ntau txheej": cov khoom siv tiv thaiv kev poob, cov khoom nres siab tshaj plaws, cov khoom nres thaum muaj xwm txheej ceev, cov khoom siv sib txuas kev nyab xeeb, thiab cov khoom nres log. Cov no ua haujlwm ua ke los xauv lub kaw lus tam sim ntawd yog tias muaj qhov tsis zoo, tiv thaiv kev sib tsoo. Cov khoom siv hluav taws xob zoo ua kom muaj kev tswj hwm zoo nrog kev ua haujlwm hloov pauv yooj yim. Tsis tas yuav muaj kev cob qhia - cov neeg ua haujlwm hauv tsev thiab cov neeg siv ntiag tug tuaj yeem siv nws yooj yim rau kev nres tsheb sai thiab tsis muaj kev txhawj xeeb.
Muaj ntau yam siv tau, lub kaw lus no haum rau yuav luag txhua qhov xwm txheej. Hauv cov zej zog qub, nws ntxiv qhov chaw nres tsheb yam tsis muaj av ntxiv, txo qhov kev sib tsoo thiab kev tsis sib haum xeeb. Hauv cov chaw ua haujlwm, cov khw loj, thiab cov chaw ua lag luam, nws ua kom qhov chaw siv tau zoo tshaj plaws thiab txhim kho kev paub ntawm tus neeg siv. Hauv cov vaj thiab cov tsev so ntiag tug, nws tuaj yeem tso ntau lub tsheb thaum teeb tsa thaj chaw kom zoo. Nws kuj tseem haum rau kev hloov kho qhov chaw nres tsheb me me thiab kev teeb tsa tus qauv chaw nres tsheb ib ntus, hloov kho rau ntau qhov chaw nrog kev siv sai thiab kev siv nyiaj tsawg.
Cov qauv kev lag luam qhia tau hais tias cov tshuab nres tsheb uas tsis hnyav, pheej yig, yooj yim rau nruab, thiab muaj kev nyab xeeb yog qhov tseem ceeb rau kev daws teeb meem nres tsheb hauv nroog. Lub tshuab nres tsheb hydraulic plaub-ncej tshiab no ua tau raws li qhov xav tau ntawm kev ua lag luam, muab "kev siv tau qhov chaw siab, kev teeb tsa yooj yim, kev nyab xeeb ruaj khov, kev saib xyuas tsawg, thiab kev siv tau dav". Mus tom ntej, nws yuav txuas ntxiv hloov pauv, txhawb nqa kev hloov kho chaw nres tsheb ntse, siv zog ntau. Nrog kev ua tau zoo txhim khu kev qha, nws daws cov teeb meem tseem ceeb ntawm kev nres tsheb thiab txhawb nqa kev nyob hauv nroog thiab kev pabcuam thauj mus los.
