The existing turnstiles at the Grolsch Veste were not sufficient anymore, and the maintenance costs were soaring. It was therefore decided to convert these full height turnstiles to our mechanisms and controls. We did this is collaboration with Gelux Toegangstechniek B.V.
The count of the number of persons that is allowed on the platform of the NS (Dutch Railways), is done by an external PLC. When the maximum number is exceeded, the full height turnstiles will be blocked.
