Who can tell me about the rotation principle of Feng Shui Ball?

Feng shui ball safety clamp system is an essential safety device for elevators. When the elevator is speeding, running out of control or the suspension device is broken, the safety clamp system of the balloon will quickly stop the elevator car on the guide rail to keep it in a static state, thus avoiding casualties and equipment damage accidents. Feng Shui ball and safety clamp should meet the performance requirements after inspection in the elevator production process, but the safety technical performance of the elevator depends not only on the design and manufacturing quality, but also on the installation and debugging quality to a great extent. Especially after the elevator is used for a period of time, the parameters of the balloon and the safety clamp device will change, or their functions will be weakened or lost due to wear, corrosion and fatigue. I hope my answer can help you.
