What are the advantages of dowty retarder as a continuous speed regulating device for peak load regulation

In recent ten years, the operation practice of marshalling stations at home and abroad has fully proved that the dowty retarder, as a continuous speed control equipment for hump, has the following four advantages:

1. Only when the gradient of the hump shunting yard is properly designed, the use of the dowty retarder can make the rolling stock basically reach the coupling of the coupler and the ditch, thus reducing the time for the shunting machine to go down the hump, making full use of the effective length of the shunting line, shortening the marshalling operation time, improving the capacity of the hump disintegration, the capacity of the shunting yard line storage and the capacity of the rear marshalling of the shunting yard.

2. If the arrangement of dowty retarder is reasonable, the rolling speed of vehicles can be kept balanced to avoid high-speed collision, so as to reduce the damage rate of vehicles and goods to the minimum.

3. Since the dowty retarder can automatically control the rolling speed of the vehicle without external energy and control device, it is impossible to interrupt the operation due to the failure of the existing control device. Even if a few dowty retarder are accompanied, the whole system is stable and reliable, and the operation can still be carried out without interruption.

4. The cost of dowty retarder is low and the installation is simple. The indoor maintenance period of the dowty retarder installed in the shunting line is 3-4 years, and the components are light and small, so it is convenient to repair and replace.
