Comprehensive inspection of the KBB revolving door system
During the KBB revolving door maintenance at Capella Hanoi Hotel, Sonha Auto’s technical team carried out a comprehensive inspection of the entire door system to evaluate its operating condition and identify any signs of wear before they could develop into unexpected failures.
The maintenance work included:
- Inspection of the motor, gearbox, and drive system.
- Inspection of the controller, safety sensors, and related control devices.
- Inspection of the drive mechanism, guide rail, and mechanical components.
- Adjustment of the revolving speed, operating modes, and technical parameters according to the manufacturer’s specifications.
- Cleaning of equipment, inspection of fastening points, and tightening of mechanical connections to ensure stable system operation.
Regular automatic door maintenance not only helps detect operational abnormalities at an early stage but also minimizes the risk of unexpected breakdowns. This enables building owners to significantly reduce repair costs while maintaining uninterrupted building operations, especially during periods of increased guest traffic.

KBB revolving door at Capella Hanoi Hotel continues to operate reliably after more than five years of service
The KBB revolving door at Capella Hanoi Hotel was supplied, installed, and commissioned by Sonha Auto in 2019. After more than five years of continuous operation at the hotel’s main entrance, the system continues to deliver reliable performance, smooth revolving motion, and fully meets the hotel’s daily operational requirements.
This is not only a testament to the quality and durability of the KBB revolving door system but also demonstrates the effectiveness of scheduled maintenance performed at the appropriate intervals and in accordance with established technical procedures. Routine inspections help keep mechanical components, control systems, and safety sensors operating at their optimum condition, extending equipment service life while minimizing the risk of operational interruptions.
For facilities with exceptionally high service standards, such as five-star hotels, maintaining a revolving door system in optimal operating condition is essential not only for ensuring safety but also for delivering an outstanding guest experience from the very first moment visitors enter the building.
