Fire protection device, has gate fields including closing planes that are spaced at distance relative to each other in parallel, and cooperating with lifting device, which includes winding shaft for safety belts of gate fields

摘要

The device has a lifting gate (1) including two gate fields (2, 3), which are vertically movable in a region before a through hole (9). The door fields are displaceable from an upper opening position into a vertically-offset, lower closing position by a lifting device (T) including safety belts (4, 5). The gate fields include closing planes (E, E'), which are spaced at a distance relative to each other in parallel. The gate fields cooperate with the lifting device, which includes a winding shaft (8) for the belts of the gate fields.
