Digital rail cant device for track inclination measuring

rail cant device known as superelevation, cross level, or cross fall, refers to the difference in height between the outer and inner rails on a curved section of track. Here's a breakdown:
Function:
When a train travels around a curve, centrifugal force pushes the train outwards. Cant counteracts this force by tilting the track inwards, essentially banking the curve.
This inward tilt helps the train navigate the curve safely by:
Distributing the weight of the train more evenly across both rails.
Reducing the lateral force on the rails, minimizing wear and tear.
Preventing the wheels from putting excessive pressure on the outer rail and potentially derailing.
Measurement: Cant is typically measured as the difference in elevation between the top surfaces (heads) of the outer and inner rails.
Proper cant is crucial for safe and comfortable train travel on curves.
The cant of railway specified in China is 1:40. If the track bottom slope is not set correctly, it will have a certain impact on the locomotives and vehicles when the train passes.
If the cant of railway is too large on one side and too small on the other side, although the track gauge, track distance, and level are all within the limit, when the EMU with lighter axle weight passes, the pressure of the wheel tread will leave the center of the rail and shift to the center of the track. It is slightly inclined to the outside, causing the car body to sway. In particular, if the cant of track is too large on a section of rail on one track, and the track bottom slope is insufficient on a section of rail, forming an S-shaped track, the impact on the EMU will be greater, and it is easier to generate horizontal acceleration here and cause swaying.
