FIELD: construction.
SUBSTANCE: high-speed industrial louver gate comprises wing guided into side guides and drive arranged with the possibility of action at wing for its displacement from open position into closed position and vice versa. In open position wing is arranged without contact on spiral section of side guides arranged in area of gate link. Louvre gate is arranged with balancing device. Drive is arranged with two cantilevers that are hingedly joined to wing end on the side of link and are installed at the distance from each other along gate width with the possibility of synchronous rotation around rotation axis in central zone of spiral section. Distance between areas of cantilever joint to wing and axis of cantilever rotation may vary.
EFFECT: prevention of wing locking element damage in case the latter collides with a foreign object.
