Is there a protective measure for the elevator bottom and the top of the lift?

The buffer is a protection device provided for this purpose. This protection device is composed of spring type and hydraulic type, depending on the speed of the elevator. When the car is lying on the buffer, it is called the bottom. At this moment, the buffer will relieve the impact force of the elevator car and will not cause serious injury to the passengers in the elevator.
