Walibi Holland secures the newest attraction with trapped key interlocks
The trapped key interlocks from Fortress Interlocks are widely used on machines and processes in various industries, but is it possible to secure a roller coaster with a trapped key system? Definitely! Since last year, the newest roller coaster “UNTAMED” in Walibi Holland has been secured with the trapped key system from Fortress Interlocks.

The increasing safety requirements for new attractions require a robust and reliable security system. By applying the Trapped key interlock system it is made impossible for Walibi Holland maintenance personnel to enter the danger zone when the attraction hasn’t been secured in advance.
At the invitation of Wiebe Damstra (Project Manager Walibi Holland) Unique Safety Products has implemented the solution to realize the safety of this roller coaster.
The solution is very accessible but extremely reliable, says Wiebe Damstra: “The Fortress Interlocks trapped key system has proven itself. We will therefore use these products more often for future attractions ”.
The application works as follows:
Figure A: Key switch
By turning the green key the attraction will be shut off.
Figure B: Key exchange unit
When the green key is placed in the key exchange unit, the blue keys can be extracted. The green key stays trapped.
Figure C: Mechanical door lock
The mechanical door interlocks can be opened with the blue keys. The yellow key, which is released from the door interlock, is taken into the danger zone by the maintenance personnel as a personal safety key. After the yellow key is released, the blue key remains trapped.
