1 the axle beam is adopted 20Mn seamless pipe .
2 Adopting one-piece press forging and special heat-treatment to ensure the great loading capacity .
3 the axle spindle is processed by solid forging and heat-treatment , in this way ,the spindle has strong strength
4 Adopting the Submerged -arc welding to make the whole beam more reliale .
5 to testing the axle quality ,we use the solid and crack detection technology .
