AUTOMATICALLY ADJUSTING ESCALATOR HANDRAIL SYSTEM

摘要

A passenger conveyor system includes a handrail adjustment mechanism that automatically adjusts the tension imposed on the handrail. A first tension device is positioned on a first side of the handrail drive mechanism. A second tension device is positioned on a second side of the handrail drive mechanism. Depending on the direction of handrail movement, one of the two tension devices imposes an automatically adjustable amount of tension on the handrail to maintain a desired effective length of the handrail.
