FIELD: elevator mechanics.
SUBSTANCE: invention relates to methods of ensuring safe operation of elevators. Invention implies mechanical interlocking, in which any movement of elevator cabin with open cabin doors becomes impossible. Locking is performed by automatic fixation of movable part of catcher mechanism relative to guides at opening of doors, that, in its turn, implies "landing" of cabin on catchers (that is rigid fixation of cabin on guides) in case of cabin start with open cabin doors.
EFFECT: technical result of present invention is significant increase in elevator operation safety.
