To prevent the digression accidents caused by locomotive s bandage relaxation, Zhengzhou train station put forward the scheme of wheel-set equipped with buckle.

On-line system of monitoring locomotive tyre loose is designed by means of techniques of infrared radiation measurement and Hall sensor measurement.

Tyre loose results in serious security accidents of locomotive digression, so it is significant to monitor the condition of tyre loose for safe driving on railway.

Many locomotive units make great and active efforts in the field of preventing it, but they often pay more research on one aspect that produces tyre relaxation.
