If the balance state of the car and the counterweight weight is destroyed after one rescue is finished, the trapped people are rescued by releasing the brake and sliding the car; if after the rescue is carried out by pushing once, the car is pushed for a certain distance due to the limited pushing stroke of the pushing device, and the balance state can not be damaged, the process is repeated until the balance state of the car and the counterweight is damaged, and then the trapped people are rescued by releasing the brake and sliding the car.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications, changes and variations may be made by those skilled in the art. Any modification, replacement, or improvement made without departing from the spirit and principle of the present invention shall fall within the protection scope of the present invention.
