Lifting gate with plate armouring in guide tracks

摘要

The armouring (12) comprises a number of plates (14) which are rigid, cover the width of the gate aperture, and can be angled in relation to one another. Two guide tracks (2) are arranged, one on either side of the gate aperture. The guide tracks issue in the entry (8) of the lifting gate in an inwardly running spiral section (10) in which the armouring (12) can be moved in the open position of the gate, so that the plates (14) are positioned in a spiral-form path and contact-free in relation to one another. The spiral section (10) of the guide tracks has a horizontally running, separately insertable extension section (62).
