We propose a new regular position stopper mechanism of the running wagons being capable of the wide application about the weighty matter storing system. It is composed from the magnetic brake and the spring system installed on the wagon. The wagon decelerates in the preselected speed level by the magnetic brake. The brake mechanism installed in the wagon collides against the stopper and comes to a stop at the regular position suppressing the shock by the action of the spring system. It gives the distinction that the wagon is without using the feed-back control system and makes the rapid stopping action. About making up the 1.5ton wagon running test equipment, we made a clear for the fundamental design methods, analyzing the action modes, and stopping about the error 1mm.
