Abstract
A movable platform having a fall prevention device is arranged in a shaft of an elevator system and is operated by a corresponding method for securing the movable platform. The movable platform includes a complete machine room used in an expandable elevator for a building under construction. The movable platform can be moved vertically along guide rails. In order to secure the movable platform during movement, the fall prevention device includes at least one arresting device that is arranged on the movable platform and which can be brought into engagement with the guide rail if necessary. A locking element arranged on the movable platform interacts with a safety component arranged along the movement path, and can, if necessary, actuate the arresting device together with an arresting braking system of an elevator car attached to the movable platform, the locking element thus blocking a possible downward motion.
