This second truss, in the form of an arc, or arch, was to be suspended below, which would rotate on the rails through 360 degrees. The arc also had rails on which the unit supporting the feed would move for the feed's elevational positioning. A counterweight would move symmetrically opposite to the feed for stability and, if a hurricane struck, the whole feed could be raised and lowered.
This architectural element, shaped like an arch or curve, was intended to be suspended below, facilitating rotation on rails through 360 degrees. The curved structure also featured rails for precise vertical positioning of the unit supporting the feed. A counterweight ensured stability, enabling the entire feed system to be raised and lowered in response to severe weather conditions.
