Rail xub pwg tau dav thov hauv kev tsheb ciav hlau tsim kho thiab kho cov haujlwm, tshwj xeeb tshaj yog cov ntxaij vab tshaus nrog cov tshuab tsheb ciav hlau thiab kev kub ceev (50KG, 85KG, 90 / 91LB, 115RE / 136RE, UIC54 & UIC60 Rail). Los ntawm kev siv cov tsheb ciav hlau, qhov ruaj ntseg ntawm txoj kev tsheb ciav hlau tau txhim kho, thiab kev pabcuam lub neej ntawm txoj kev sib tw. Nws txoj haujlwm tseem ceeb nyob hauv qab no.

 

• Txhawb kev sib tw:Muab kev txhawb nqa ruaj khov los tiv thaiv cov ciav hlau los ntawm kev hloov chaw.

 

• Hloov Chaw:Lub cev hnyav thov ntawm txoj kev tsheb ciav hlau yog tus neeg sib tw tau faib rau lub txaj ballast kom tiv thaiv tau ntau dhau los.

 

• Deformation tiv:Txo cov kev ntxhov siab tshwm sim los ntawm ib puag ncig cov kev ntxhov siab xws li kub thiab av kom tiv thaiv txoj kev los ntawm deformation, pob txha lov, thiab lwm yam teeb meem.

 

 

Gnee RailMuaj cov kev sib txawv ntawm cov tsheb ciav hlau sib txawv kom tau raws li cov neeg yuav tsum tau ua, cov ntses yas, cov duab sib tw ntawm cov qhua tuaj ua si, peb yuav khoom siv cov khoom tsim nyog raws li cov khoom lag luam.
