These guidelines are intended to give recommendations for safely working on and around Gimbals/Motion Bases. Gimbals/Motion Bases are generally one-of-a-kind, purpose-built devices designed to simulate real-world movement. Challenging environments, such as an airplane in flight, a ship in a storm, and many others may be simulated through the use of a gimbal. Gimbals/ Motion Bases are typically used to move cast, crew, and sets through a number of programmed or choreographed motions, and can range in complexity from small-scale, seesaw-type devices moved by simple leverage to complex, multi-axis powered motion bases controlled by a computer.
