It is attached.

When the elevator basket reaches a predetermined floor and the basket is temporarily stopped, the spring 44 brakes the brake piece module 42 when the attraction of the brake piece module 42 is released by the electromagnet module 41 of the plate type brake 4. By pushing toward the wheel 51, the brake piece module 42 is pressed against the brake wheel 51, the turning of the brake wheel 51 is stopped, and the elevator basket can be stopped at a desired floor.
When the drive of the brake wheel 51 is restored, the electromagnet module 41 attracts the brake piece module 42, the brake piece module 42 is released from the pressure of the brake wheel 51, and the operation of the brake wheel 51 is restored. When the brake piece module 42 is repositioned, the damping pad 45 provides a cushioning function to reduce noise.

When the plate type brake 4 is not used for a certain period of time, the damping pad 45 is worn and thinned, the air gap becomes large, and the distance between the electromagnet module 41 and the brake piece module 42 is reduced in the conventional method. , The noise of the damping pad 45 was reduced. When adjusting the distance between the electromagnet module 41 and the brake piece module 42, the lock members 43 at the four corners of the electromagnet module 41 and the brake piece module 42 are adjusted, but the adjustment amounts of the plurality of lock members 43 are actually matched. It wasn't easy to get it done. Therefore, the work of adjusting the distance between the electromagnet module 41 of the conventional plate type brake 4 and the brake piece module 42 takes a lot of time and is inefficient.
