What function does a buffer serve in an elevator system?

• A. To control the movement of the cab
• B. To absorb shock at the limits of travel
• C. To ensure proper door function
• D. To connect the motor and cab

Answer: (B)

In an elevator system, a buffer plays a crucial role by absorbing shock at the limits of travel. When an elevator reaches the end of its travel—either at the top or bottom of its shaft—there can be a sudden stop that may generate significant forces. Buffers are designed to dampen these forces, preventing potential damage to the elevator components and enhancing passenger safety. They provide a cushioning effect that absorbs the kinetic energy generated during this sudden halt, which helps to protect both the elevator and its passengers from harsh impacts. Understanding the purpose of buffers highlights the focus on safety and reliability in elevator design, ensuring that even in extreme situations, the elevator operates within safe limits.
