Kev kuaj ua haujlwm:Txhua qhov kev txav mus los yog kuaj yam tsis muaj kev thauj khoom. Kev mus ncig, nqa, thiab kev ua haujlwm qis yog kuaj xyuas kev taw qhia thiab smoothness.

Kev kuaj hluav taws xob:Rwb thaiv tsev tsis kam, grounding, thiab functionality ntawm tag nrho cov kev ruaj ntseg circuits (tso txwv switches, thaum muaj xwm ceev nres) raug txheeb xyuas.

Partial Load Test:Yog tias qhov chaw siab tso cai, ib qho kev sim nrog ib nrab load (xws li, 50-75T) tuaj yeem ua.

Theem 7: Dismantling, ntim & Shipping

Lub crane yog dismantled rau hauv kev thauj mus los modules.

Dismantling:Cov qauv ua tib zoo sib cais rau hauv cov khoom: lub ntsiab girders (feem ntau faib ua ob), ob txhais ceg, trolley, hoist, thiab hluav taws xob panels.

Ntim:Cheebtsam yog ntim rau ntawm cov ntoo crates thiab thav duab los tiv thaiv kev puas tsuaj thaum caij tsheb npav. Cov khoom tsis zoo xws li lub cev muaj zog thiab cov khoom siv hluav taws xob yog huab cua- pov thawj.

Theem 8: Ntawm -Site Erection & Commissioning

Qhov kawg thiab tseem ceeb theem ntawm tus neeg siv khoom qhov chaw.

Kev npaj qhov chaw:Lub hauv paus thiab cov ntsia hlau yuav tsum tau muab ntsia thiab txheeb xyuas rau qib thiab kev sib raug zoo los ntawm tus neeg siv khoom ua ntej.

Erection:Siv mobile cranes, cov khoom sib sau ua ke hauv qhov tseeb: cov tsheb thauj khoom kawg tau muab tso rau ntawm cov ntsia hlau, cov girders tseem ceeb tau nqa thiab txuas nrog, ua raws li cov tsheb thauj khoom thiab cov hoist.

Kev sib txuas zaum kawg:Kev sib txuas tshuab thiab hluav taws xob tau ua tiav ntawm -site.

Commissioning & Load Testing:Qhov no yog qhov kawg validation.

Tsis muaj -Load Test:Tag nrho cov haujlwm crane tau sim dua.

Static Load Test:Kuaj nrog125% ntawm Rated Peev Xwm (250 Tons). Lub load yog lifted tawm hauv av thiab tuav rau ib lub sij hawm los xyuas txog cov qauv deflection thiab kev ncaj ncees. Kev ntsuas raug coj mus.

Dynamic Load Test:Kuaj nrog110% ntawm Rated Peev Xwm (220 Tons). Lub load yog nqa thiab txav mus los ntawm txhua qhov kev ua haujlwm (hoisting, trolley mus ncig, gantry mus txawv tebchaws) los xyuas qhov kev ua tau zoo nyob rau hauv cov xwm txheej zoo.

Daim ntawv pov thawj & Kev Them Nyiaj:Tom qab kev sim ua tiav, tus thib peb - cov neeg soj ntsuam lossis cov koom haum tswj hwm tau muab daim ntawv pov thawj ua raws. Lub crane raug xa mus rau tus neeg siv khoom nrog tag nrho cov ntaub ntawv (phau ntawv, kos duab, ntawv xeem, ntawv pov thawj).

Rhiav saib:

Lub tuam txhab tau teeb tsa cov cuab yeej ntse tswj kev tswj hwm lub platform, thiab tau teeb tsa 310 teeb (teev) ntawm kev tuav thiab vuam robots. Tom qab ua tiav ntawm txoj kev npaj, yuav muaj ntau tshaj 500 teeb (sets), thiab cov khoom siv sib txuas sib txuas yuav ncav cuag 95% . 32 cov kab vuam tau muab tso rau hauv kev siv, 50 tau npaj los nruab, thiab automation tus nqi ntawm tag nrho cov khoom kab tau mus txog 85%.
