摘要：
The present invention relates to a seat for the movable point in a cradle of a crossing frog incorporated in long welded rails and the process for production of such a seat. The seat is characterized in that the connection between the movable point (1) and the element (2") of the cradle constituted by two rails (3 and 4) is effected by an essentially mechanical assembly. The invention is more particularly applicable to the field of the construction of railway equipment, particularly, crossing frogs.
