The application of permanent magnet synchronous technology in the field of elevators has made the traction structure of anti-rope sheaves an indispensable moving part of elevators. The elevator anti-rope assembly raises the elevator car while generating low frequency vibration transmission, which causes noise impact on the adjacent indoor environment.

The Shenri team has developed an elevator anti-rope damping system with ultra-low vibration and noise through long-term practical research and experiments. In many domestic elevator noise complaint cases, Shenri applied the system's noise reduction technology to the original elevator's anti-rope wheel vibration damping structure to reform the test, which proved that the product can effectively reduce the impact of low-frequency vibration of the elevator operation, and the noise reduction effect is significant.
