Abstract

A mobile storage system includes an anti-roll safety brake for preventing undesired rolling of a movable carriage. The anti-roll brake is engaged continuously so that a portion of the power required to move a carriage is expended in overcoming the friction force of the brake. Upon removal of the power source, such as de-energizing an electric drive motor, the anti-roll brake prevents all unpowered rolling of the carriage, and it continues to hold the carriage in place until the drive motor is again energized. The anti-roll brake is particularly useful in mobile storage systems in which the guide rails cannot be installed in a level attitude.
