Abstract
The tension on the moving handrail drive and/or step chain of a passenger conveyor such as an escalator or moving walkway is automatically released when the conveyor is shut down; and is automatically reapplied when the conveyor is started up again. Undesirable compression and localized flattening of the elastomeric components of the conveyor are thus avoided.
