Dynamic Load Test:Ib qho kev ntsuas ntawm 110% ntawm lub peev xwm ntsuas yog nqa thiab muab tso rau hauv txhua qhov kev txav: mus ncig, trolleying, thiab hoisting. Qhov no kuaj cov kev ua haujlwm thiab kev nyab xeeb hauv kev ntxhov siab.

Dimensional soj ntsuam:Qhov loj me (span, nqa qhov siab, thiab lwm yam) raug txheeb xyuas qhov kev txiav txim.

Cov ntaub ntawv:Tag nrho cov qhabnias xeem, daim ntawv pov thawj rau cov ntaub ntawv thiab welds, thiab cov khoom siv phau ntawv tau muab tso ua ke rau hauv ib daim ntawv xa tuaj zaum kawg rau cov neeg siv khoom.

 

Theem 8: Dismantling, ntim & Shipping

Dismantling:Lub crane tau ua tib zoo disassembled rau hauv cov laj thawj, shippable Cheebtsam (xws li, ob lub ntsiab girders, ob lub tsheb kawg, trolley unit, hoist, hluav taws xob panels, runway rails).

Ntim:Cov khoom xyaw yog ntim los tiv thaiv kev puas tsuaj thaum lub sij hawm thauj dej hiav txwv lossis av. Cov khoom siv feem ntau yog ntim rau ntawm cov ntoo crates. Cov khoom siv hluav taws xob yog ntim thiab khaws cia rau hauv rooj ntoo.

Shipping:Txhua qhov chaw raug cim rau kev txheeb xyuas yooj yim thiab qhov chaw reassembly. Tom qab ntawd lawv raug xa mus rau cov neeg siv khoom qhov chaw rau kev teeb tsa los ntawm cov chaw tsim khoom cov kws tshaj lij lossis cov neeg siv khoom tus kheej.

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%.
