Rail Gap Adjuster for Sale
A rail gap adjuster is a type of railway maintenance machinery used to adjust the gap between rails. The rails are affected by temperature, which causes the gap between the rails to become larger or smaller. The rail gap can be kept within the allowable range through a rail gap adjuster. To ensure the safety and stability of the train. Unlike rail tensor, Rail tensor is used for seamless rails, and rail gap adjuster is used for gapped rails. It adjusts the rail gap locally by hydraulic means without changing the overall stress state of the rail. The rail gap adjuster is important in railway maintenance. Timely adjustment of the track gap can significantly reduce the risk of derailment, while also reducing wheel-rail impact and lowering maintenance costs. AGICO’s rail gap adjuster can complete the track gap adjustment work of 50kg/m, 60kg/m, and 75kg/m rails.

Advantages of Rail Gap Adjuster
High Accuracy
Rail gap adjuster can achieve high-precision rail gap adjustment of ±1mm level through the hydraulic system. Reduce the error of manual adjustment and reduce the risk of derailment by more than 60%.
High Efficiency
Compared with manual adjustment, the rail gap adjuster reduces the single adjustment operation time to 3-5 minutes. Moreover, it is easy to operate, reduces line blocking time, and improves efficiency by 5-8 times.
Strong Adaptability
The rail gap adjuster is equipped with rail devices of different specifications and is suitable for various types of crane rails. The compact structure can be used in a variety of environments.
Reasonable Design
The rail gap adjuster has an ergonomic foldable handle design with an operating force of no more than 50N. The non-slip rubber base and magnetic fixings ensure stable positioning of the device on the rails.
Rail Gap Adjuster Structure and Working Principle
Taking the YTF 400 II Hydraulic Rail Gap Adjuster as an example, let’s show you the structure and working principle of the rail gap adjuster:
- 1. Front clamp
- 2. Piston rod
- 3. Oil cylinder
- 4. Oil return valve (the other side is a spare oil return valve)
- 5. Middle clamp
- 6. Pull rod
- 7. Slant iron (6 pieces)
- 8. Rear clamp
- 9. Large safety pin
- 10. Wrench
- 11. Outer rocker arm
- 12. Oil tank
- 13. Return spring
- 14. Small safety pin (2 pieces)
Working principle of push rail: First, use the front and middle clamps to clamp the rail gap adjuster firmly onto the two rails. The hydraulic oil is pressurized by the hydraulic pump and delivered to the hydraulic cylinder, and the piston in the cylinder extends outward under the action of the hydraulic pressure. When the piston extends, it applies an axial thrust to the clamped rail through the clamp or internal structure. This increases the gap between the rails.
Working principle of pull rail: First, use the middle and rear clamps to clamp the rail gap adjuster firmly onto the two rails. The hydraulic oil is pressurized by the hydraulic pump and delivered to the hydraulic cylinder. The piston in the cylinder retracts inward under the action of the hydraulic pressure. When the piston rod retracts, an axial tensile force is applied to the clamped rail through the clamp or internal structure. This reduces the gap between the rails.
Application Scenarios of Rail Gap Adjuster
Rail welding construction
When welding rails, the two sections of rails need to be precisely aligned and a welding gap must be reserved. The rail gap adjuster can move rails into position while they are waiting to be welded.
Broken rail processing
When the tensile stress of the rail is too large and brittle fracture occurs, The rail gap adjuster can push the broken rail to close the fracture or reserve a gap for welding.
Rail expansion treatment
When the temperature is high in summer, the rails will expand, causing them to bend and deform. The rail gap adjuster can open the rail gap, release the pressure and make the rail return to a straight line.
Special line maintenance
In special areas such as bridges and tunnels, the rail gap adjuster can finely manage and control the track gaps in these areas.
