Railway Track Joint

The Railway Track Joint is a crucial part of the railway track structure, which allows the track to have a certain amount of room for expansion and contraction while ensuring the smooth operation of the train.

It is a device that connects two sections of rail, which allows the track to produce a certain deformation when subjected to external factors such as temperature changes and train loads, so as to maintain the continuity and stability of the track.

feature

Adapt to deformation

allow the track to produce a certain deformation when the heat expands and cold shrinks, to avoid damage to the track due to excessive stress.

Maintain continuity

Ensure that the track can maintain good continuity after deformation to maintain the smooth operation of the train.

Transfer load

Effectively transfer the train load to the subgrade and track bed below the track to ensure the overall stability of the track structure.

Other Products

Connection technique

Thermal composite welding (thermal shear welding)

Two sections of rail are joined together by preheating the end of the track and using molten metal filler material to form a strong and lasting connection.

Friction welding (non-continuous welding)

Using high pressure and rotary friction to heat the two ends of the rail to join them together. This method is often used to connect long distance rails, providing a strong connection strength.

Mechanical connection

The two sections of rail are connected together by bolts, splints and other fasteners, which is relatively simple and easy to maintain.
