Abstract
Official abstract text for this publication.
A braking apparatus main body has: a movable body; and an electromagnetic actuator that displaces the movable body in a direction of contact with and separation from a rotating body that is rotated relative to a hoisting machine main body. An adjusting collar is screwed into an adjusting threaded aperture disposed on the electromagnetic actuator. The adjusting collar is disposed between the hoisting machine main body and the electromagnetic actuator. The electromagnetic actuator is mounted to the hoisting machine main body by a mounting device in a state in which the hoisting machine main body bears the adjusting collar. A position of the braking apparatus main body relative to the hoisting machine main body is adjusted in a direction in which a distance between the electromagnetic actuator and the rotating body changes by adjusting an amount of thread engagement of the adjusting collar in the adjusting threaded aperture.
