Txhua Qhov Kev Ntsuas Kev Ntsuas:Hoisting, trolley, thiab gantry taug kev hauv txhua qhov kev qhia thiab nrawm.

Kev ua haujlwm ntawm Outrigger:Kev ntsuas lub voj voog ntawm hydraulic stabilizers.

Load Test:

Static Load Test:Hoist 125% ntawm lub peev xwm ntsuas, tuav rau 10+ feeb. Tshawb xyuas kom ruaj khov deformation.Outriggers yuav tsum tau siv.

Dynamic Load Test:Ua haujlwm txhua qhov kev taw qhia ntawm 110% rated peev.

Kev Ntsuam Xyuas Kev Nyab Xeeb:

LMI / RCL Calibration:Txheeb xyuas qhov tseeb thiab tsis siv neeg ua haujlwm ntawm ntau lub radii.

Anti-Kev Sib tsoo System Test.

Emergency Stop & Limit Switch Verification.

Tilt Tswb Test(simulating av tsis ruaj khov).

 

Theem 8: Dismantling, Preservation & Shipping

Lub crane yog systematically dismantled rau hauv loj modules:Girders, Ob txhais ceg (nrog bogies txuas), Trolley, Fais Fab Pob, thiab Tswj Vaj Huam Sib Luag.

Tag nrho cov chaw nres nkoj hydraulic thiab machined nto raug kaw thiab khaws cia.

Cheebtsam yog tshwj xeeb crated los yog mounted rau thauj thav duab rau dej hiav txwv los yog hnyav thauj khoom thauj.

 

Theem 9: Qhov Chaw Tsim Kho & Kev Tso Cai (Post-Kev xa khoom)

Kev Tshawb Fawb Foundation:Kev txheeb xyuas ntawm cov kabmob hauv av muaj peev xwm thiab theem ntawm qhov chaw ua haujlwm.

Mechanical Re- sib dhos:Cov Cheebtsam tau txuas dua tshiab siv lub siab - lub zog bolts.

System Re-kev sib txuas:Cov kab hluav taws xob thiab hydraulic tau txuas dua -.

Qhov Chaw Xeem Kawg:Re- kuaj cov haujlwm,steering calibration ntawm qhov tseeb nto, thiab kawgLMI calibrationnrog cov ntawv pov thawj ntsuas qhov hnyav.

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%.
