AREMA Standard Rail Joint Bars Specifications
Txhua lub teb chaws ua raws li cov qauv tshwj xeeb hais txog kev tsheb ciav hlau qhov ntev, yuav tsum tau xaiv cov kev tsheb ciav hlau sib koom ua ke raws li cov qauv no. GNEE tsim cov kab sib koom ua ke raws li ntau yam qauv, suav nrog DIN, GB, AS, AREMA, thiab BS cov qauv. Qhov tseem ceeb, rail sib koom ua ke npaj rau kev xa tawm mus rau Tebchaws Meskas ua raws li AREMA tus qauv.
Hauv qab no yog cov diameters ntawm kev tsheb nqaj hlau sib koom ua ke rau kev lag luam Asmeskas:
