Modification of  the ride “Tonnerre 2 Zeus” [Zeus’ Thunder]

Client expectation 

Within the context of the attraction’s renovation, the Astérix amusement park wanted to invest in a new track, as well as a new train for its most popular ride, Zeus’ Thunder.

The park was therefore looking for an integrator capable of linking the new elements to the existing automatism, while responding to new improvement requirements:

– modernisation of the maintenance track

– improvement in the lift’s grip speed

– modernisation of the braking system

– modernisation of the control voltage


DV GROUP solutions 

In order to understand the project correctly and reach the objectives, we proposed a two-phase management:

Phase 1: Pre-design

We carried out onsite surveys of the electrical cabinet installation and the various captors and actuators which would be modified or integrated into the track and on the doubling of the maintenance track. We then modelled the robot program in the design office. Lastly, we organised an onsite visit in partnership with TÜV. These steps allowed us to draft the operational specifications file related to the train modifications (track and doubling of the maintenance track), which we presented to our client.


Phase 2: Implementation of the project following validation

  • Replacement of the robot’s CPU, with an increase in memory size in order to increase reactivity.
  • Addition of an on/off switch at technical room level in the station and the maintenance track
  • Integration of Flip Flop management for the second maintenance track in the technical room
  • Replacement of the tyre casings allowing the train to brake before arriving in the station
  • Cabling of the various actuators and captors allowing the ride to be driven correctly
  • Exchanges with the SYSTEMA security, monitoring and validation bodies
  • Replacement of the lift cupboards and station management cabinets
  • Modification of the cycle times allowing a faster train grip speed
  • Connection of the lift drive
  • Addition of an operator detection mat in order to validate presence during the ride operating phases
