Abstract
A mobile storage system includes a safety brake for smoothly stopping a moving carriage. The brake is operated from readily assessible positions in the aisles between carriages, thus minimizing the risk of injury to persons in the aisles if another person starts a carriage. The brake includes a notched plate which normally rotates with a carriage axle. Upon actuation of a safety switch, a toothed lever mounted to the carriage frame engages the plate, thereby preventing it from rotating. Friction discs on either side of the plate dissipate the carriage kinetic energy into heat and thereby stop the carriage. The control circuit includes a timer so that the person may safely leave the aisle before the carriage can again be moved.
