Title: ELEVATOR DEVICE
Abstract:
Provided is an elevator device that includes a wedge-shaped braking element for gripping a guide rail on a lifting body. A speed governor rope is installed in a hoistway in parallel with a suspension body of the lifting body. The elevator device is provided with a first biasing part for biasing the braking element upward by gripping the speed governor rope in the speed governor in the case where the lifting body has abnormally accelerated, and a second biasing part for biasing the braking element upward by utilizing the motion generated by the falling of the lifting body at the time of breakage of the suspension body. At least one of the first biasing part and the second biasing part is separated from the braking element.
