Problems in the use of dowty retarder

When the dowty retarder is used in marshalling stations, it must also adapt to the characteristics of the dowty retarder and meet its technical requirements. We have seen at some marshalling stations that although the station operation rules have also been formulated, it is difficult to implement and fully implement it. There are objective factors There are also subjective reasons. Give examples to illustrate.

The station expressly stipulates that in the installation section of the dowty retarder, there is a dowty retarder on one side of the rail. Iron shoes cannot be placed on the other side of the rail, but due to improper control of three parts, the personnel in the shunting area saw that the car was going to speed, picked up the iron shoes and placed them on the rail. As a result, the wheels on the other side crashed some of the dowty retarder, almost It did not cause the vehicle to disconnect. The allowable speed of the locomotive passing through the marshalling station (the allowable speed of the structure) is 25km/h, but when the locomotive is in the whole field or when the car is picked up, the peak speed is very fast. , The speed can reach more than 30km/h. Ask the driver why he is driving so fast. He said that it is too hot to drive fast to keep it cool. When the programmed train changes from the rear or leaves. It is also the old speeding. Especially when the second half of the train reaches the end of the marshalling line. The speed can reach 40km/h. When there is a caboose, the caboose "jumps" on the retarder, which not only affects the life of the dowty retarder, It is also easy to cause the caboose or light car to disconnect. There have been accidents of caboose and light cars falling off the tail at the marshalling station, which is mainly caused by this reason. Therefore, there are also problems of one kind or another in the use of deceleration roofs at stations.
