The main stage ramp is an integral part of the 800m2 LED floor which can be raised and lowered to allow entry of performers from “below ground”; the most memorable scene is of 200 soldiers of the ‘Cent-suisses’ regiment marching up in formation. See the main project page for a short video taken during the show, and how we have integrated the ramp model into our videos.
Our model is of the 800m2 LED floor – at a scale of 1:30 the model as viewed above is 150 cm x 60 cm. The full main stage is more than 1000m2
The ramp is seen only as a completed model in our videos, so no attempt has been made to replicate the original construction ‘below the surface’. Thus, we have used readily-available ‘meccano’ parts such as girders, gears, and pulleys. The scale of the pit and ramp structure is correct, with the motor and mechanism being contained within it.
After the long-awaited completion of the arena ramp model, our reward was to begin integrating it into our documentary. First trial view here from the north end of the LED floor, towards the south. ⬇
Our model fits perfectly into any view of the arena floor – even if shooting from quite a distance is required to get the correct angle for some shots.
⬇ One cool clip to develop a few more seconds of our documentary – we begin with a high angle shot and switch to an almost flat stage level shot, and angles in between. Jazz group is from our live recording of ‘Quantact‘.
Re-Vamping the Ramp.
The initial ramp model was our first experience in modeling. With lessons learned from the stairway model, there are now improvements in progress — so “re-vamping the ramp” !
Firstly we have reduced friction and enabled a smoother rise without recourse to video editing. Secondly, there was an inevitable gap between entry pathway and the ramp due to our flawed design in placing of the raising pulleys which are now moved backwards under the ramp itself.
Modified pulley mechanism — contiguous walkway-ramp — smooth raising.
Our ramp girders descend “below ground”. In reality the ramp is raised and lowered by pneumatic pistons, in the model we have used a single cord drum which pulls two separate double pulley reduction systems. Enjoy the ride!
