Safeguarding a rollercoaster

Machine safety in the theme park industry

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.

As the green isolation key is
released, the energy of the
roller coaster is isolated.

Entering the green key
releases the blue keys

Blue access keys are entered
to release the yellow security keys
and open the door
The employee keeps the yellow key
with him to prevent entrapment.
The blue access key is stuck until
the yellow safety key is returned.
Green power isolation key is stuck
in the key switch until all blue
access keys are returned.

Increasing safety requirements
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 ”.

Products used in this application:

Key Switch

Safety isolate installations

Door interlock

For the safe opening of doors and hatches

Key exchange unit

For isolating multiple energy sources of accessing multiple doors
