Abstract
An escalator system includes a moving step including a plurality of grooves and drivable in a travel direction. A combplate is located at at least a downstream end of the moving step relative to the travel direction at a step-combplate interface. A retraction device is configured to move the combplate along the travel direction from a normal position toward a retracted position when an entrapment of an object is detected at the step-combplate interface.
