A fire protection door in an open position is present above a traveling path of a transport vehicle. The fire protection door is capable of moving downward from the open position to a closed position along a door trajectory. The transport vehicle includes: a control portion; an area detection portion that detects an interference area, which is an area in which a portion of the transport vehicle in the traveling path overlaps the door trajectory; and a descent detection portion that detects a descent of the fire protection door. The control portion performs a retraction control such that the transport vehicle travels to the outside of the interference area when the descent detection portion has detected a descent of the fire protection door in a state in which the transport vehicle is located in the interference area.

A transport facility includes a guide rail which is disposed along a travel path extending in a travel direction through an opening of a wall and which is configured to guide traveling of a transport vehicle, and a fire door configured to open and close the opening. The fire door is configured to, in closing the opening, move toward a first side in an arrangement direction from an open position to a closed position. The fire door includes a notch penetrating the fire door in the travel direction and open on the first side to prevent the fire door from coming into contact with the first rail body and the second rail body while the fire door is moving from the open position to the closed position.

A fire damper for a ventilating fan includes a shutter and a frame provided with a flange. An opening is defined through the flange. The frame is further provided with a movable component for opening or closing the preformed opening.

An autonomous grid storage system (1) arranged in a warehouse space (12). The autonomous grid storage system is divided within the warehouse space, for example on a single floor of said space, into a plurality of sub grids (10a/10b) separated by fire walls (18). One or more bridges (14) pass through openings in the fire wall to allow bin handling vehicles (210/301) to traverse between the sub grids. The openings (20) are provided with closable fire door (22).

The invention relates to a device (100) for providing a crossover point between a first region (1) and a second region (2) hermetically delimited from the first region (1) by means of a wall (10), wherein the device comprises:a lock chamber (12), which can be inserted into an opening (11) provided in the wall and which has a first opening (13) forming a crossover point between the first region and the lock chamber and which has a second opening (14) forming a crossover point between the second region and the lock chamber;at least one peripherally circulating element (15), which has at least one passage opening (15.1; 19.1; 15.2; 19.2) and can be moved in relation to the first and the second opening of the lock chamber so that at least a first state, in which the at least one passage opening is substantially aligned with the first opening of the lock chamber and enables access from the first region into the lock chamber and the peripherally circulating element covers the second opening of the lock chamber substantially completely, and a second state, in which the at least one passage opening is substantially aligned with the second opening of the lock chamber and enables access from the second region into the lock chamber and the peripherally circulating element covers the first opening of the lock chamber substantially completely, can be selectively effected.

A transport device and a transport method is provided for a container treatment plant. The transport device comprises at least one transporter for transporting containers to or away from a treatment station of the container treatment plant, wherein at least one transporter is positioned displaceable in relation to another one of the transporters to provide a closeable spatial separation between the at least one displaceable transporter and the other transporter.
