- the basket moves up and down.
- the hoisting machine is provided with a brake, and when an abnormality is detected, such as when the elevator is accelerated abnormally, the hoisting machine brake operates and the car can be stopped safely.
- An emergency stop device is provided on the car for holding the guide rail and decelerating the car.
- a governor rope In order to drive this emergency stop, a governor rope is installed in a loop shape by two pulleys on the upper and lower sides in parallel with the main rope in the hoistway, and is connected to the car via the emergency stop. Then, it moves up and down in conjunction with the car.
- the pulley at the top of the governor rope is a governor, and the governor is equipped with a mechanism that restricts the movement of the governor rope when it rotates at an abnormal speed.
- the pit at the lower end of the hoistway is equipped with a shock absorber, which is designed to decelerate the car when it cannot be decelerated by an emergency stop, but a normal governor depends on the position of the car. Since it operates by detecting a constant speed, there is a problem that the assumed collision speed of the shock absorber increases according to the rated speed, the shock absorber becomes large, and the pit of the hoistway becomes long.
- the inertial force of the governor rope itself increases in proportion to the acceleration of the car.
- the emergency stop is activated regardless of the car speed.
- the shock absorber can be downsized and the pits can be shortened.
- the emergency stop that is operated using the rotational inertia of the governor has a problem that the inertial force fluctuates due to vibration of the governor rope.
- this effect becomes significant, and there are some conditions in which it is difficult to shorten the shock absorber.
- Another system uses a structure (slack type) that detects the breakage of the main rope not by dropping the car but by changing the tension at the connecting portion of the car and the main rope and operates an emergency stop (see Patent Document 2). ).

- the present invention has been made in view of the above, and can suppress an increase in the time until the emergency stop operates while having two types of urging mechanisms that drive the emergency stop brake element.
- An object is to provide an elevator apparatus.
- the elevator apparatus of the present invention has a wedge-shaped brake for gripping the guide rail on the lifting body, and a governor rope is installed in the hoistway in parallel with the suspension body of the lifting body.
