The buffer is the last protective device in the elevator pit. When the elevator hits the buffer, the buffer absorbs or consumes the kinetic energy and potential energy of the elevator, so that the elevator or the counterweight safely decelerates until it stops.
Generally, the buffer is located in the pit, and some elevators are located on the top of the car or the bottom of the counterweight. The setting of the buffer on the upper part of the car should be satisfied. Only when the counterweight is completely pressed on the buffer, the buffer installed on the car can be activated.
