Products Description
Rails play a very important role in China's railway transportation. There are three types of tracks: heavy rails, light rails, and lifting rails. The difference between heavy rails and light rails is that the weight of the rails per unit length is different. Rails with a weight of more than 24kg per meter are called heavy rails; rails with a weight of less than 24kg per meter are called light rails. Heavy rails can be divided into general starting heavy rails and starting heavy rails according to their uses. General starting heavy rails are mainly used on railway tracks, and starting heavy rails are mainly used on the guide rails of cranes.

Rails with a weight of more than 24kg per meter are called heavy rails; rails with a weight of less than 24kg per meter are called light rails. Heavy rails can be divided into general starting heavy rails and starting heavy rails according to their uses. General lifting rails are mainly used on railway tracks, and lifting rails are mainly used on the guide rails of cranes. From the cross-section of the rails, the shapes of the two are slightly different. The start heavy rail is shorter in height, wider and thicker in waist, while the start heavy rail is the opposite.
Heavy rails are different from light rails. They are the tracks for heavy vehicles, not the weight of the rails themselves, but they are indeed important: because the tracks for heavy vehicles are thicker and therefore heavier, the specifications of the rails are higher. Rail weight Rail specifications are expressed in kilograms of net weight per meter.
Heavy rails refer to rails with a weight greater than 60 kg per meter. Heavy rails can be divided into general rails and crane rails. Ordinary rails refer to rails used for laying railway trunk lines, dedicated lines, curves and tunnels. Among them, the standard rail length is 25m and the 50m or 500m high-speed rail length is continuously welded, and the curved rails are laid. The slightly shorter lengths are 24.96m, 50.92m, etc. The specifications of ordinary rails for 500m high-speed railways are, 60.75.100 (kg/m).
Heavy rail has a larger cross-section than light rail and can withstand greater forces. The early railway trunk lines used 78 kg rails, but now use 60 kg and 75 kg rails.The application scope of heavy rails includes regional railways, intercity railways, urban railways, urban rapid railways, and subways.
