A method of operating an elevator system is provided and includes: identifying that a brake of an elevator car fails to fall upon removal of a braking force; temporarily hovering the elevator car in place to allow the elevator car to be emptied; controllably moving the elevator car to the top or bottom of a hoistway in an unbalanced direction defined as a function of the relative weight of the elevator car and counterweight and a torque applied to the elevator car for driving the elevator car upward or downward; and confirming that the brake fails to fall or provides sufficient holding torque.
提供了一种操作电梯系统的方法,并且所述方法包括:识别电梯轿厢的制动器在移除制动力时未能落下;使所述电梯轿厢暂时悬停在适当位置,以允许所述电梯轿厢被清空;在不平衡的方向上可控地将所述电梯轿厢移动到井道的顶部或底部,所述不平衡的方向根据所述电梯轿厢和配重的相对重量以及施加到所述电梯轿厢以用于向上或向下驱动所述电梯轿厢的转矩来限定;以及确认所述制动器未能落下或提供足够的保持转矩。
