  • Publication number: 20220380176
    Abstract: An elevator device having a safety gear is disclosed that makes it possible to prevent a braking state detecting switch from being turned on in case of power interruption, while becoming activated by an electrically operated actuator. This elevator device includes a safety gear which is provided onto an elevator car and an electrically operated actuator which activates the safety gear and has a braking state detecting switch (6) to detect a braking state of the safety gear. The braking state detecting switch (6) is actuated by a mechanism (10, 82, 83) which is mobilized by a braking element (51) of the safety gear. Displacement of the braking element (51) when power supply is lost keeps the braking state detecting switch (6) in an off state. Displacement of the braking element (51) in a braking by the safety gear turns on the braking state detecting switch (6).
