Abstract (en)
In an elevator safety system, an engagement disc with a small diameter, which is rotated integrally with a rotary body, is provided coaxially with the rotary body. The engagement disc is rotatable relative to the rotary body. However, the engagement disc is rotated integrally with the rotary body under normal conditions. The rotation of the engagement disc is mechanically stopped by an engagement-disc stopping mechanism. The engagement-disc stopping mechanism is operated by an actuator. When the rotation of the engagement disc is stopped by the engagement-disc stopping mechanism, the rotation of the rotary body relative to the engagement disc is transmitted to a rotary-body stopping mechanism by an interlocking mechanism. Then, the rotary body is stopped by the rotary-body stopping mechanism.
