Why did the elevator suddenly fall?

1, the problem of holding the brake may be that the brake is improperly adjusted and there is a problem, or the brake shoe of the brake is seriously worn, causing the elevator to fall. 2. The elevator falls due to the imbalance between the car and the counterweight, but this usually happens in the process of installation and debugging, and it will not happen in the elevator that has been put into use after acceptance. 3. The rope groove of the traction sheave is seriously worn, causing the elevator to fall.

Many people are worried that the elevator will suddenly fall during operation, but in fact, "elevator falling" is not a real fall. There are generally two situations of "elevator falling": emergency stop during the operation of the elevator: the safety loop or door lock loop is disconnected during the operation, which causes the elevator to stop, and passengers may feel numb in their legs, which is actually caused by the emergency stop of the elevator.

When the elevator breaks down in operation, it will automatically return to the base station to reset: this is also the misunderstanding of "the elevator has fallen" by most people, and the probability of this happening is similar to the probability of buying a lottery ticket of 5 million. In fact, it is often an illusion for passengers to feel that the elevator is descending rapidly, because the elevator itself has many safety protection systems and devices, which can cope with various emergencies and protect passengers.
