Revolving Door refurbishment For Cambridge University Research Facility

We were initially called to site as the door had become difficult to push manually and was making a noise whilst rotating. We provided a quotation to refurbish the door and replace the bearings at the most convenient time to the customer.

As we purchase parts from this particular manufacturer, we were able to order the parts prior to dismantling the door. Due to the many different bearings used by different manufacturers it is important to change them like for like.

With all of the system removed we cleaned the mat well, drum wall and ceiling as this would be easier with the doors removed. Each glass door leaf was placed upon trestles and the patch fittings removed to allow us to replace the gaskets.

Also, we replaced any worn brush seals as these are used to seal from the environment. Generally, the ones at the bottom of the door and at the outer edge wear as they constantly rub when the door is operated.

The other important item is the bottom locks which due to their location will always contract dirt and water. Each time they are used the pin goes into a hole in the floor ring and then retract back into the lock case. We removed all of the locks, cleaned and lubricated them to ensure a smooth and easy operation.
