2, light rail: nominal weight per meter is less than or equal to 30kg rail. The quality requirements of the proportion of light rail track is low, only requires to test its chemical composition, tensile strength, hardness and drop hammer test. Main purposes: mainly used for light rail forest, mining, factories and construction sites, etc. laying temporary transportation routes and light lines and light locomotive cranes carts and trolley tracks.
