ABSTRACT:
An aerial support platform is supported to extend below, and intermediate of, a pair of parallel cables mounted along respective opposite walls of a studio. A carriage rides on each of the parallel cables, and another pair of cables extends to connect the pair of carriages. A third carriage sits on the other pair of cables, and a series of further cables extend vertically from that carriage to the platform. The pair of carriages positioned on the opposite walls of the studio are controlled to move in tandem, and the third carriage has controlled movement between those carriages. The platform may be raised or lowered relative to the third carriage, and thus has three linear axes of motion. The platform has two additional axes of motion, both rotational. One is around a vertical axis and another is around an axis normal to the vertical axis. Cinematographic equipment may be fixed to the platform, which can then be oriented using a computer at a remote location.
