Abstract
A cable failure device for a cable-operated door operated by a tensioned cable, the cable-operated door having a movement guided along a fixed structure, such as a guide rail. The cable failure device is configured for cooperating with the tensioned cable so as to immobilize the cable-operated door with respect to the fixed structure in the event of a loss of tension in the cable. The cable failure device included a support bracket for mounting the cable failure device onto the door, a guiding assembly operatively mounted for guiding the movement of the door along the fixed structure, and a braking assembly operatively mounted onto the support bracket, and operable between a rest position where the guiding assembly is allowed to guide the door along the fixed structure, and an operable position triggered by a given loss of tension detected in the tension cable where the braking assembly engages a portion of the fixed structure for braking movement of the cable-operated door with respect to the fixed structure. The cable failure device also includes a safety arm operatively connected to the braking assembly and cooperating with the tensioned cable so as to detect the given loss of t…
