摘要

The brake has a stirrup (1) with a movable cap (2) containing the stop mechanisms for braking and release. The braking action is effected by a toothed link (10-12) on a chain (3) which drives a toothed pinion (4) on which the release assembly is mounted. The release assembly has a centrifugal or inertial actuator which is independent of the braking system. Release is initiated by exceeding a given speed. The chain (3) for braking (3) is vertically tensioned inside or outside of the guide rail for the door.
