To improve the braking work of the swing arrestor used at the end of the marshalling yard,the mechanical property,the stroke of cylinder and the braking work is discussed.

It is worthiness that we attention and research which application retarder to adjust speed of over loading vehicle and use arrester to prevent wagon runaway,for example prevention wagon runaway on U.

Basis on locale operation actuality and track condition of receiving and departure yard of jining station,it point to install model TDJGST-202 retarder for double critical speed to solve train runaway in receiving and departure tracks,pass the operation and practice for one year,it introduces the experience and method of overhaul and maintain of arrester.

TDJ-GST-1 stop retarder of high speed locking is a continuous anti-running equipment for stopping cars,which creat from china,beside prossessing the function of common stop retarder in retardation,stopping wheels,anti-running,it also resolve key technical problems on automatic judging speed,hight speeding locking,locking speed can be adjusted according to actual need.

The Clasp TDK retarders are applied in the master retarder area and group retarder area ,controlled retarders are applied in the tangent retarder area ,common retarders are applied in the classification,stop retarders are applied at the tail of hump of the mechanized hump in the Yuci station.

This paper introduces the determination of amount of retarder layout of stop retarder ,position and method of retarder layout and effect in application after stop retarders are installed.
