Abstract
The invention provides an elevator having a car movable along guide rails mounted in a shaft. The elevator comprises an inspection control station mounted on top of the car and accessible via a movable control station cover, blocking means for selectively preventing movement of the car into a safety space within the shaft and actuation means for actuating the blocking means. The actuation means is configured for concurrent movement with the control station cover. Accordingly, a temporary safety space is automatically created within the shaft as the maintenance technician opens the control station cover to move the car using the inspection control station.
