When the emergency happens, the elevator will often fall which causes huge damages. An airpad system is installed into the elevator as the similar function to the airbag in the vehicles. When an unexpected situation is detected, the airpad in profile will explode against the wall before the safety gear starts in order to slow down the falling speed by enhancing friction. There are also airpads underneath the bottom of the elevator playing a role in absorb impact.
