In the field of rail applications, the 15KG GB light rail plays an important role in many scenarios with its specific specifications and dimensions. Understanding its specifications and dimensions is of great significance for reasonable selection and ensuring the stable operation of the rail system.
The rail height of the 15KG GB light rail is 79.37mm. This height design takes into account the stability of vehicle driving and the bearing capacity of the rail structure. In practical applications, such a rail height can provide good guidance for the vehicle, so that the vehicle remains stable during operation and reduces bumps and shaking.
The head width of the light rail is 42.86mm. The reasonable head width ensures good contact between the wheel and the rail head, effectively disperses the vehicle load, reduces rail wear, and extends the service life of the rail. When the vehicle is running, the wheel and the rail head are in uniform contact, the pressure is evenly distributed, and the local stress concentration is reduced.
The waist thickness is 8.33mm, which plays a key role in the strength of the light rail. Sufficient waist thickness can enhance the bending resistance of the light rail, so that it can maintain good structural integrity when bearing vehicle pressure and dynamic loads, and is not easy to deform or break.
The theoretical weight of the P15 GB light rail is 15.2kg/m, which not only meets certain load-bearing requirements, but also ensures the convenience of track laying and maintenance. During the construction process, such a weight is convenient for workers to carry and install, reduce labor intensity, and improve construction efficiency.
The 15KG GB light rail mostly uses Q235B/55Q as a material. This type of material has good strength and toughness and can adapt to complex use environments. In a humid or corrosive environment, this material can maintain stable performance and ensure long-term reliable operation of the track. Its specifications and dimensions are closely designed around actual use needs. From rail height, head width to waist thickness, each parameter has been carefully considered, laying a solid foundation for the wide application of light rail in various industries.
