Description

FIG. 3 shows one of the brake structures suitable for the elevator according to FIG. The elevator includes means 10, 20 for starting braking of the brakes 11, 21, and this brake corresponds, for example, to the guide rails 12, 22 of the elevator. In this case, the brake is disposed so as to decelerate the force required to reduce the speed of the car / counterweight from the guide rail. The means 10 and 20 are of the following types. That is, using these means, when the tension of the hoisting rope is decreased, braking of the brake provided in the elevator car and / or the brake provided in the counterweight is started. Thus, by using these means 10, 20, the brakes provided on the counterweight are easy to brake when the elevator car suddenly stops or at least slows down. Similarly, the brake provided in the elevator car is configured to brake when the counterweight suddenly stops or at least its speed decreases. This suppresses or at least significantly reduces the continued movement of the elevator car or counterweight that moves in the opposite direction of the elevator car or counterweight described above after the elevator car or counterweight suddenly decreases in speed. it can. Preferably, if the brake 11 is an elevator car brake, this brake is a safety device corresponding to the guide rail, preferably also connected to the elevator overspeed prevention device (eg the rope of the overspeed prevention device). Safety device.
