[0003] When the traditional machine room-less elevator suddenly encounters a power failure, the general emergency rescue method is to release the brake of the drive device, and use the unbalanced weight of the elevator car and counterweight to make the elevator car move up or down. If the car is heavy at this time, the car will move downward; if the counterweight is heavy at this time, the car will move upward. When the car runs near the leveling area, the people trapped in the car can be rescued. However, if the car and the counterweight are basically in a balanced state, even if the brake of the driving device is released, the car will not move up and down, and the rescue function cannot be realized.
