The plastic dowel in sleeper manufacturer tells you that the railway line is composed of a variety of railway accessories, and different railway accessories, installed in different parts, play different roles. As a railway accessories factory, our company provides various types of railway accessories, such as rails, sleepers, connecting parts, track beds, anti-climbing equipment, rail supports and turnouts. The plastic dowel in sleeper manufacturer tells you that in order to let everyone know more about railway accessories, they will briefly introduce the types and functions of railway accessories.
Plastic dowel in sleeper manufacturers tell you that rails are railway equipment and important railway equipment, and steel rails are the main symbol of railway equipment. In order to effectively resist the lateral force of the wheel and rail, a component installed on the outside of the rail. The plastic dowel in sleeper manufacturer tells you that rail supports are generally installed on the outside of the outer strands of the small-radius curved track to prevent excessive lateral force from causing excessive lateral displacement of the track when the train passes the curve, and even causing the rail to overturn. The manufacturer of Plastic dowel in sleeper tells you that general rail supports are used for wooden sleeper rails. In most of the switch point rails, rail braces are also installed on the outside of the basic rails to improve the lateral rigidity of the rails, and the rail braces have more shapes.
The plastic dowel in sleeper manufacturer tells you that when a train is running, it often produces a longitudinal force acting on the rail, which causes the rail to move longitudinally, and sometimes even drives the sleepers to move together. This longitudinal movement is called crawling. Plastic dowel in sleeper manufacturers tell you that crawling generally occurs on the main line of the double-track railway, the heavy vehicle direction of the single-track railway, the braking range on the long downhill and when entering the station. The plastic dowel in sleeper manufacturer tells you that sleepers must not only support the rails, but also maintain the position of the rails, and transfer the huge pressure from the rails to the track bed. It must have a certain degree of flexibility and elasticity. When the train passes, it can be deformed appropriately to cushion the pressure, but after the train passes, it must be restored as much as possible. Sleepers include wooden sleepers and concrete sleepers.
