Specifications and dimensions of 18KG GB light rail

Jun 24, 2025 Leave a message

In the rail transportation system, 18KG GB light rail has become the preferred solution for many light rail scenarios with its precise specifications and dimensions. Its specification design not only meets the load-bearing requirements, but also takes into account the convenience of installation and maintenance. ​

 

The rail height of 18KG GB light rail is 80mm. This height enables the rail to have good vertical support capacity, effectively disperse the vehicle load, and ensure the smooth running of the train. The matching height of the rail surface and the wheel can reduce the impact force during operation, improve ride comfort and rail durability. ​

 

The head width of the light rail is 40mm. The reasonable head width ensures the close fit between the wheel and the rail, making the vehicle more directional during driving. The uniform force distribution greatly reduces the wear rate of the rail, extends the service life of the rail, and reduces maintenance costs. ​

The waist thickness is 10mm, and the thicker waist design significantly enhances the bending resistance of the light rail. When bearing heavy loads or dynamic loads, the 18KG light rail can maintain a good structural form, avoid deformation or fracture caused by stress concentration, and provide protection for the safe operation of the rail system. ​

 

The theoretical weight of the P18 GB light rail is 18kg/m. This weight ensures the strength of the track while facilitating the construction workers to carry and lay it. In scenarios such as industrial and mining enterprises and forest transportation, a moderate weight can improve construction efficiency and reduce labor costs. ​

In terms of materials, the 18KG GB light rail often uses 55Q high-quality carbon steel, which has high strength and good toughness and can adapt to complex environments. Whether it is a humid and rainy area or an area with a large temperature difference, this material can maintain stable performance and ensure long-term and reliable operation of the track. These carefully designed specifications and dimensions make the 18KG GB light rail play an indispensable role in various light rail projects.
