[Case Study] Maintenance and Repair Work for Smoke Exhaust Windows

Proper inspection and maintenance protect the owners and managers.

We would like to introduce a case study of maintenance work on smoke exhaust windows carried out by Operator Construction Co., Ltd. The first smoke exhaust window could not be opened or closed from the control box, and the window was temporarily closed with a wire rope. Damage was also observed in the control box. The other two smoke exhaust windows did not fully open, and there was an abnormal heaviness in the handle during operation. Damage was also noted in the handle box. [Case Study] ■ Project Name: September 16, 2018, Toyonaka City, a certain condominium 1st Floor Entrance Smoke Operator Repair Work ■ Cause: The wire rope of the first smoke exhaust window was broken. It is believed that the flexibility of the wire rope decreased due to aging, leading to hardening of the piping and poor sliding. The other two locations did not have broken wire ropes, but it is also believed that the flexibility of the wire ropes decreased due to aging, resulting in hardening of the piping and poor sliding. *For more details, please refer to the external link or feel free to contact us.
