SYSTEM FOR ARRESTING THE MOVEMENT OF OBJECTS TRAVELING ALONG A DEFINED PATH

摘要

An emergency system for arresting the movement of a traveling object such as an elevator car wherein the momentum of the object is absorbed by the physical extension of elongated metal members engaged by the moving object. Two or more of the elongated metal members are provided on each side of the path of the object with one end of such members being restrained against movement in at least one direction and the other end being engaged by a projection provided for that purpose on the object and free to move with the object and impart extension to the metal members.
