| 摘要 |
The invention relates to a method for operating a lift installation (1), and to one such lift installation (1). The lift doors (4,6) are actuated by a door drive (22) according to a displacement curve. At least one sensor unit (10-12) detects pressure ratios and/or air flows. An evaluation unit (13) determines a displacement curve, from a plurality of displacement curves, which is optimum in terms of the detected pressure ratios and/or air flows. |
