The elevator buffer is the core component of the elevator safety system. As the ultimate safety guarantee, it is installed at the bottom of the elevator shaft to prevent roof or floor accidents caused by the loss of control of the car or counterweight.
Elevator buffers convert the kinetic energy of uncontrolled falls into elastic potential energy (spring type) or into thermal energy through fluid damping (hydraulic type), achieving controllable deceleration and parking. They are an indispensable safety guarantee device in modern vertical transportation.
