The Orbital Stage is used to move two to three scenery items which are constructed on its platform. The desirable scenery appears at the appropriate moment with MANUAL or AUTO rotational movement of the mechanism.
This mechanism is based on the principle of circular platform rotation. Three electrical gearboxes, placed inaposition1200onefrom another, rotate a metal coil system of about 6-9m diameter, upon which the platform is based. The vertical load is received by the wheels of the mechanism. The motion of engines is absolutely controlled and coordinated through rotational movement sensors. The position of the platform is displayed on the control panel in real time. Motion takes place with constant control of acceleration and deceleration rates. It has at least three programs for position selection: three programs to change position by 1200and two programs to change position by 1800.
