Usually Jet-fans are hung from a ceiling of a road tunnel using supporting devices in Japan. Since many vehicles pass under the Jet-fans, falling of any parts or components of the Jet-fans should be avoided to ensure comfortable driving without accidents. Therefore, it is very important to monitor the supporting condition of the Jet-fans for the maintenance. We developed a new monitoring system using load cell that detects the loading condition of supporting devices. This new system uses the load cell to monitor the Jet-fan total operating condition, such as slack of supporting devices, vibration caused by unbalance of the fan blades. Therefore, this system can be applied to maintain the safety operation by continuous monitoring remotely for the suitable maintenance. This paper shows an experimental work that is simulating actual condition of a Jet-fan in a road tunnel and also shows the result of the effect of changes of loading condition. Furthermore, as a diagnostic criterion for the result of monitored condition, we adopted statistical diagnostic method.
