The wedge-shaped design of the sector plate can flexibly match curved tracks of different radii, solving the problem of poor adaptability of traditional straight pads in curves and reducing rail side wear and sleeper stress concentration.
The wedge-shaped structure distributes the longitudinal and lateral
forces generated by the passing train to a larger area of the sleeper,
reducing local pressure, sleeper cracks and ballast pulverization.
