This is a model based on the sunroof cassette. The end of the track is level with the stage deck while the other end is lifted up with a set of levers.

Like the patents, this design uses the the same force that moves it forward to prop the arms up and change the angel  of the platform when it reaches the end of its track.

I still want to find a way to have a physical lock that can be done and undone by the same cylinder that move the platform. I want to have a structure that can remain safe should the pneumatic or hydraulic cylinder loses pressure.
