Retractable tribunes for sports, culture and education buildings
COS engineers, manufactures and installs telescopic tribunes for multipurpose culture halls, education buildings and sports buildings. The propulsion for opening and closing is created by the innovative rigid chain system.
COS tribunes are engineered in co-creation with architect, client and end user and apply to the European standards and national regulations.
The rigid chain system is an electrical propulsion system to push the tribune platforms forward and pull them backwards. This propulsion system is - in contrary of drum engines - completely independent of the floor.
Not only a perfect opening and closing of the tribune is guaranteed, also the operation of the chairs can be automated within the same system.
