Safe exposition world thanks to DICTATOR back checks
The hall doors of the Messe Munich, which open to the outside, are extremely frequented during expositions. And they are often exposed to gusts of wind, air draughts and carelessness. In the past, this resulted in heavily damaged doors again and again: broken glass, damaged door closers and hinges, etc. Beside the repair costs this could also affect the stream of visitors during fairs by doors being out of use.
DICTATOR provided adjustable back checks. The back checks control the complete opening of the door and limit its opening angle. But this implies not a higher effort for the user as the damping only starts when the opening speed of the door becomes too fast, e.g. by a gust of wind or by handling it too roughly, an important advantage, especially on doors as frequented as those at the Messe Munich.
