The advantage of the sliding door is first and foremost that of drastically reducing the costs and times required for cleaning the booth’s gratings, because their disappearance during the paint application phase means there is no risk of them becoming dirty as a result of the paint. The upshot is a simple system that does not require any special maintenance.
The gratings on the floor of the application booth consist of two horizontal pedestrian “shutters” located on the sides of the booth. During the application phase the gratings wrap themselves around the counter pulleys located on the outside of the booth, causing the normal walkway to disappear. However, during cleaning or maintenance the gratings return to their original position, allowing operators to access the booth.
