ABSTRACT OF THE DISCLOSURE An arrester device, e.g. for an elevator cage or counterweight, has a wedge housing, an active wedge acting on one side of an elevator guide and activated by a separate transmission member, such as a rope, and a counterwedge acting on the elevator guide from the opposite side. The movements of the wedges and the counter wedge are directed to pass along inclined guide surfaces, the distance between the top margins of the guide surfaces being equal to or larger than the distance between their lower margins. The angle of inclination of the guide surfaces equals the wedge angles of the wedge and the counterwedge, respectively. Furthermore, the wedge housing comprises a force member, such as a spring, which exerts on the counterwedge a force substantially parallel to the respective guide surface.
