In addition, it is uneconomical because it is equipped with a decelerating detection device that detects the necessary and normal deceleration of the elevators.
- a pressure vessel filled with fluid is provided instead of the elastic member, and the pressure in the pressure vessel and the viscosity of the fluid are adjusted to adjust the pressure vessel. Since the pressure is adjusted, fluid pressure is constantly applied to the pressure vessel, and management of fluid pressure leakage, etc. is required.

- the purpose is to obtain an elevator emergency stop device that does not damage the lifting body or counterweight.
- the deceleration during the braking operation is alleviated, causing the passenger to feel uncomfortable or damaging the lifting body or the counterweight.
- the purpose is to obtain an elevator emergency stop device.
