Above the Vevey arena are critical cable installations for a “Spidercam” and for the performance iconic “Libellule” (dragonfly).
In green on the plan above are the cables supporting and guiding the movement of the dragonfly. The “trolley” is seen in the third photo below, and travels above the level of the Spidercam cables. However, it theoretically would still be possible for an accident to occur if the dragonfly were to be lowered at the wrong place and wrong time. The Steadicam is of course fully motorized and remote controlled (see the four separate cable drum towers), while control of the dragonfly is done by hand – two gloved technicians pulling the horizontal and vertical position control cables, receiving information from an observer in the arena and verifying their actions on separate video monitors.
Their operation is on the ground at the north end, at public entrances H&G, while the take-off and landing point for the Libellule is above them, at the rear of the upper stage – behind the large video screens located there.
