Product Description

Main uses
1. Adjust the height of the rails
Correct the height deviation of the rails caused by the subsidence of sleepers, the settlement of ballast or the deformation of the foundation, and restore the designed elevation of the tracks.
2. Compensate for track settlement
In soft soil subgrades, bridge transition sections or freeze-thaw zones, prevent uneven settlement from causing uneven track smoothness.
3. Enhance orbital stability
Improve the force distribution of rails and sleepers and reduce the geometric deformation of the tracks.
4. Extend the maintenance cycle
Adjust the track height temporarily or for a long time to reduce frequent track lifting and tamping operations and lower maintenance costs.

 

Typical usage scenarios
Maintenance of existing lines
Sleeper sinking repair: In concrete sleeper or wooden sleeper sections, add heightening boards to restore the rail surface elevation.
Track bed settlement treatment: It is applicable to local track settlement caused by dirty and compacted ballast.
2. New line construction and track adjustment
Fine-tune the geometric state of the track: When laying high-speed railways and heavy-haul railways, slightly adjust the height of the rails to meet the requirements of smoothness.
Bridge and subgrade transition section: Alleviate the uneven settlement of the track caused by stiffness differences.
3. Special geological sections
In areas affected by frost heaving: After the steel rails are raised due to frost heaving in winter, they will be restored to their original positions by raising the plates when they melt in spring.
Soft soil subgrade: Dynamic adjustment for continuous settlement caused by soil consolidation.
4. Turnouts and curve sections
Switch zone height adjustment: Keep the switch and flush with the surface of the base rail.
Curve overheight correction: In conjunction with the outer rail overheight setting, ensure the balance when the train passes through.

 

The types of height-adjustable plates
1. Metal height adjustment plate
Material: cast iron, steel plate or stainless steel, with strong wear resistance, suitable for heavy-haul railways.
Features: Reusable, but requires anti-rust treatment.
2. Composite material height adjustment plate
Material: Nylon, rubber or polyurethane, good elasticity, shock absorption and noise reduction.
Features: Insulating and corrosion-resistant, but it may age under long-term load.
3. Adjustable pad
Equipped with bolts or wedge-shaped structure, supporting stepless height adjustment.

 

The railway rail lowering height plate is a key component in track maintenance, used to quickly correct the height deviation of the steel rail and ensure the safety and comfort of train operation. Its flexibility and economy make it widely used in line maintenance, fine adjustment of new lines and special geological sections, and it is an indispensable part of the modern track maintenance system.
