Abstract (en)

[origin: EP2308788A1] In an elevator hoisting machine braking apparatus, a brake shoe and a movable core are coupled by a coupling member. The movable core is forced by a forcing body in a direction in which the brake shoe contacts a rotating body. The movable core displaces the brake shoe away from the rotating body in opposition to the force from the forcing body by electric power being supplied to an electromagnet. A holding helical portion is disposed on either one of the brake shoe or the movable core. An adjusting helical portion that can be screwed together with the holding helical portion is disposed on the coupling member. A position of the adjusting helical portion relative to the holding helical portion is fixed by a fixing means. The fixing means fixes the position of the adjusting helical portion relative to the holding helical portion by pressing the adjusting helical portion against the holding helical portion in a direction in which the brake shoe and the movable core approach each other.
