The carriage is operatively configured to move longitudinally along the first and second guide tracks and to move laterally between the first and second guide tracks. The ladder is pivotally mounted to the overhead track system. A lateral carriage brake is provided which prevents lateral movement of the ladder, and a longitudinal carriage brake is provided to prevent longitudinal movement of the ladder. The latch is operatively configured to affix the ladder to the carriage.
