What’s steel rail?

Steel rails are the load-bearing and guiding elements in a railway or crane track. The train rail profile is an asymmetrical I-beam with a wide flat bottom that fits on the railroad track. Steel rail profiles consist of a head at the top. The web supports the head and is comparatively thinner. At the base of the component is the foot that rests on the track.

Wheels rest on top of the rail, with wheel flanges extending downwards on the insides of the rails. The devices are produced in fixed lengths with end-to-end joints creating a continuous surface. One method of linking the sections is bolting them together using fish plates.

2. Application

Steel rails are employed in a broad spectrum of transportation functions, outlined by the following categories:

Mass transit—passenger railways, underground rail, trams.

Freight and logistics—bulk material transport.

Cranes, fixed track lifting equipment, for short haul and high load transport.

3. Types

There is light rail and heavy rail. Light rail and heavy rail are classified by the weight per meter of rail. The light rail weighs below 30kg/m, while the heavy rail above 30kg/m. Light rail usually include 8kg, 15kg, 18kg, 22kg, etc. Heavy rail includes 38kg, 43kg, and so on.

What is the crane rail? As its name suggested, the crane rail is used in the crane railway. The crane rail has its own material, dimensions, standard, and sizes. Normally, crane rail with a thicker web.

4. Specification

Different countries have different demands for the profiles and materials of steel rail, like DIN, EN, YB GB, JIS, ASTM, etc.

5. Material

The steel rail is made of steel alloy, which contains various chemical components. Why? The iron is not stable enough to sustain the train or crane. The addition of chemical components, like Mn, improves the chemical or physical performance of the final products.

Principle of rail clamp design

Principle of rail clamp design rail clamp design The rail clamp design has several functional features: 1. Adjustability: The adjustable length is 15mm, and its adjustability functions include: (1) The rail presser is easy to install, saves time, and has high precision (2) The track can be adjusted if the structure of the support beam is slightly changed. 2. Anti-loosening: Under the action of the lateral force of the track, through the force analysis of the welding RTYB, a part of these lateral forces are transmitted to the bottom seat through the upper cover plate as the pressure of the bottom edge to seat on the upper cover plate. The other part is the lateral friction between the base and the upper cover. Since the wedge-shaped action between the base and the upper cover plate is converted into the tightening force of the bolts, it has an anti-loosening effect. 3. Self-locking: The three pieces are self-locking together through the interaction of the upper cover, the base, and the

What is rail creep

What is rail creep rail creep Rail creep is also known as line crawl. The creeping phenomenon of the rail along the longitudinal direction of the line. With the increase in railway transportation tasks, the impact of the wheels on the rails when the train is running accelerates the creep of the rails. Rail creep can cause many diseases of the line. In order to prevent the occurrence of track creep diseases, it is necessary to find out the real cause of creeping in order to effectively eliminate the problem. There are two different manifestations: the rails move along the soft sleeper surface due to insufficient fastening pressure of the fasteners; the longitudinal movement of the row is caused by insufficient ballast bed resistance. The reason for this is the longitudinal force of the rail caused by the wheel rolling and longitudinal slip, train braking, the change of rail temperature, and the creep caused by the deflection and deformation of the rail under the action of the wheel load
